+# -------------- CodeIgniter Testing (4/20/2011) -------------- #
+
+
+# Introduction:
+
+This is the preliminary CodeIgniter testing documentation. It
+will cover both internal as well as external APIs and the reasoning
+behind their implemenation, where appropriate. As with all CodeIgniter
+documentation, this file should maintain a mostly human readable
+format to facilitate clean api design. [see http://arrenbrecht.ch/testing/]
+
+*FIRST PUBLIC DRAFT: EVERYTHING IS SUBJECT TO CHANGE*
+
+# Test Suites:
+
+CodeIgniter bootstraps a request very directly, with very flat class
+hierarchy. As a result, there is no main CodeIgniter class until the
+controller is instantiated.
+
+This has forced the core classes to be relatively decoupled, which is
+a good thing. However, it makes that portion of code relatively hard
+to test.
+
+Right now that means we'll probably have two core test suites, along
+with a base for application and package tests. That gives us:
+
+1. Bootstrap Test	- test common.php and sanity check codeigniter.php		[in planning]
+2. System Test		- test core components in relative isolation			[in development]
+3. Application Test	- bootstrapping for application/tests					[not started]
+4. Package Test		- bootstrapping for <package>/tests						[not started]
+
+
+## 1. Bootstrap Test
+
+Testing common.php should be pretty simple. Include the file, and test the
+functions. May require some tweaking so that we can grab the statics from all
+methods (see is_loaded()). Testing the actual CodeIgniter.php file will most
+likely be an output test for the default view, with some object checking after
+the file runs. Needs consideration.
+
+
+## 2. System Test
+
+Testing the core system relies on being able to isolate the core components
+as much as possible. A few of them access other core classes as globals. These
+should be mocked up and easy to manipulate.
+
+All functions in common.php should be a minimal implementation, or and mapped
+to a method in the test's parent class to gives us full control of their output.
+
+
+### CodeIgniterTestCase Documentation
+
+
+Test cases should extend CodeIgniterTestCase. This internally
+extends PHPUnit_Framework_TestCase, so you have access to all
+of your usual PHPUnit methods.
+
+We need to provide a simple way to modify the globals and the
+common function output. We also need to be able to mock up
+the super object as we please.
+
+Current API is *not stable*. Names and implementations will change.
+
+$this->ci_instance($obj)
+	set the object to use as the "super object", in a lot
+	of cases this will be a simple stdClass with the attributes
+	you need it to have.
+
+$this->ci_set_instance_var($name, $val)
+	add an attribute to the super object. This is useful if you
+	set up a simple instance in setUp and then need to add different
+	class mockups to your super object.
+
+$this->ci_core_class($name)
+	Get the _class name_ of a core class, so that you can instantiate
+	it. The variable is returned by reference and is tied to the correct
+	$GLOBALS key. For example:
+	$cfg =& $this->ci_core_class('cfg'); // returns 'CI_Config'
+	$cfg = new $cfg;					// instantiates config and overwrites the CFG global
+
+$this->ci_set_core_class($name, $obj);
+	An alternative way to set one of the core globals.
+
+
+## 3. Application Test:
+
+Not sure yet, needs to handle:
+- Libraries
+- Helpers
+- Models
+- MY_* files
+- Controllers (uh...?)
+- Views? (watir, selenium, cucumber?)
+
+- Database Testing
+
+
+## 4. Package Test:
+
+I don't have a clue how this will work.
+
+Needs to be able to handle packages
+that are used multiple times within the application (i.e. EE/Pyro modules)
+as well as packages that are used by multiple applications (library distributions)

+# CodeIgniter Unit Tests #
+
+*Do not merge to default until these issues have been addressed*
+
+- Clean up naming conventions
+- Figure out config stuff
+- Figure out database testing
+
+### Introduction:
+
+This is the preliminary CodeIgniter testing documentation. It
+will cover both internal as well as external APIs and the reasoning
+behind their implemenation, where appropriate. As with all CodeIgniter
+documentation, this file should maintain a mostly human readable
+format to facilitate clean api design. [see http://arrenbrecht.ch/testing/]
+
+*First public draft: everything is subject to change*
+
+### Requirements
+
+PHP Unit >= 3.5.6
+
+	pear channel-discover pear.phpunit.de
+	pear install phpunit/PHPUnit
+
+vfsStream
+
+	pear channel-discover pear.php-tools.net
+	pear install pat/vfsStream-alpha
+
+#### Installation of PEAR and PHPUnit on Ubuntu
+
+  Installation on Ubuntu requires a few steps. Depending on your setup you may
+  need to use 'sudo' to install these. Mileage may vary but these steps are a
+  good start.
+
+	# Install the PEAR package
+	sudo apt-get install php-pear
+
+	# Add a few sources to PEAR
+	pear channel-discover pear.phpunit.de
+	pear channel-discover pear.symfony-project.com
+	pear channel-discover components.ez.no
+	pear channel-discover pear.symfony-project.com
+
+	# Finally install PHPUnit and vfsStream (including dependencies)
+	pear install --alldeps phpunit/PHPUnit
+	pear install --alldeps pat/vfsStream-alpha
+
+	# Finally, run 'phpunit' from within the ./tests directory
+	# and you should be on your way!
+
+## Test Suites:
+
+CodeIgniter bootstraps a request very directly, with very flat class
+hierarchy. As a result, there is no main CodeIgniter class until the
+controller is instantiated.
+
+This has forced the core classes to be relatively decoupled, which is
+a good thing. However, it makes that portion of code relatively hard
+to test.
+
+Right now that means we'll probably have two core test suites, along
+with a base for application and package tests. That gives us:
+
+1. Bootstrap Test	- test common.php and sanity check codeigniter.php [in planning]
+2. System Test		- test core components in relative isolation [in development]
+3. Application Test	- bootstrapping for application/tests [not started]
+4. Package Test		- bootstrapping for <package>/tests [not started]
+
+### CI_TestCase Documentation
+
+Test cases should extend CI_TestCase. This internally extends
+PHPUnit\_Framework\_TestCase, so you have access to all of your
+usual PHPUnit methods.
+
+We need to provide a simple way to modify the globals and the
+common function output. We also need to be able to mock up
+the super object as we please.
+
+Current API is *not stable*. Names and implementations will change.
+
+    $this->ci_set_config($key, $val)
+
+Set the global config variables. If key is an array, it will
+replace the entire config array. They are _not_ merged.
+
+    $this->ci_instance($obj)
+
+Set the object to use as the "super object", in a lot
+of cases this will be a simple stdClass with the attributes
+you need it to have. If no parameter, will return the instance.
+
+	$this->ci_instance_var($name, $val)
+
+Add an attribute to the super object. This is useful if you
+set up a simple instance in setUp and then need to add different
+class mockups to your super object.
+
+	$this->ci_core_class($name)
+
+Get the _class name_ of a core class, so that you can instantiate
+it. The variable is returned by reference and is tied to the correct
+$GLOBALS key. For example:
+    
+	$cfg =& $this->ci_core_class('cfg'); // returns 'CI_Config'
+    $cfg = new $cfg; // instantiates config and overwrites the CFG global
+
+	$this->ci_set_core_class($name, $obj)
+	
+An alternative way to set one of the core globals.
+
+	$this->ci_get_config()  __internal__
+	
+Returns the global config array. Internal as you shouldn't need to
+call this (you're setting it, after all). Used internally to make
+CI's get_config() work.
+
+	CI_TestCase::instance()  __internal__
+
+Returns an instance of the current test case. We force phpunit to
+run with backup-globals enabled, so this will always be the instance
+of the currently running test class.
+
+### Going forward
+
+#### 1. Bootstrap Test
+
+Testing common.php should be pretty simple. Include the file, and test the
+functions. May require some tweaking so that we can grab the statics from all
+methods (see is_loaded()). Testing the actual CodeIgniter.php file will most
+likely be an output test for the default view, with some object checking after
+the file runs. Needs consideration.
+
+#### 2. System Test
+
+Testing the core system relies on being able to isolate the core components
+as much as possible. A few of them access other core classes as globals. These
+should be mocked up and easy to manipulate.
+
+All functions in common.php should be a minimal implementation, or and mapped
+to a method in the test's parent class to gives us full control of their output.
+
+#### 3. Application Test:
+
+Not sure yet, needs to handle:
+
+- Libraries
+- Helpers
+- Models
+- MY_* files
+- Controllers (uh...?)
+- Views? (watir, selenium, cucumber?)
+- Database Testing
+
+#### 4. Package Test:
+
+I don't have a clue how this will work.
+
+Needs to be able to handle packages
+that are used multiple times within the application (i.e. EE/Pyro modules)
+as well as packages that are used by multiple applications (library distributions)

+/**
+ * Session Class
+ *
+ * The user interface defined by EllisLabs, now with puggable drivers to manage different storage mechanisms.
+ * By default, the Native PHP session driver will load, but the 'sess_driver' config/param item (see above) can be
+ * used to specify the 'Cookie' driver, or any other you might create.
+ * Once loaded, this driver setup is a drop-in replacement for the former CI_Session library, taking its place as the
+ * 'session' member of the global controller framework (e.g.: $CI->session or $this->session).
+ * In keeping with the CI_Driver methodology, multiple drivers may be loaded, although this might be a bit confusing.
+ * The Session library class keeps track of the most recently loaded driver as "current" to call for driver methods.
+ * Ideally, one driver is loaded and all calls go directly through the main library interface. However, any methods
+ * called through the specific driver will switch the "current" driver to itself before invoking the library method
+ * (which will then call back into the driver for low-level operations). So, alternation between two drivers can be
+ * achieved by specifying which driver to use for each call (e.g.: $this->session->native->set_userdata('foo', 'bar');
+ * $this->session->cookie->userdata('foo'); $this->session->native->unset_userdata('foo');). Notice in the previous
+ * example that the _native_ userdata value 'foo' would be set to 'bar', which would NOT be returned by the call for
+ * the _cookie_ userdata 'foo', nor would the _cookie_ value be unset by the call to unset the _native_ 'foo' value.

+/**
+ * SessionDriver Class
+ *
+ * Extend this class to make a new Session driver.
+ * A Session driver basically manages an array of name/value pairs with some sort of storage mechanism.
+ * To make a new driver, derive from (extend) SessionDriver. Overload the initialize method and read or create
+ * session data. Then implement a save handler to write changed data to storage (sess_save), a destroy handler
+ * to remove deleted data (sess_destroy), and an access handler to expose the data (get_userdata).
+ * Put your driver in the libraries/Session/drivers folder anywhere in the loader paths. This includes the application
+ * directory, the system directory, or any path you add with $CI->load->add_package_path().
+ * Your driver must be named Session_<name>, where <name> is capitalized, and your filename must be Session_<name>.EXT,
+ * preferably also capitalized. (e.g.: Session_Foo in libraries/Session/drivers/Session_Foo.php)
+ * Then specify the driver by setting 'sess_driver' in your config file or as a parameter when loading the Session
+ * object. (e.g.: $config['sess_driver'] = 'foo'; OR $CI->load->driver('session', array('sess_driver' => 'foo')); )
+ * Already provided are the Native driver, which manages the native PHP $_SESSION array, and
+ * the Cookie driver, which manages the data in a browser cookie, with optional extra storage in a database table.

Subject: [PATCH 0055/5397] Fixed int typecasting of limit parameter in
 DB_active_rec.php

If an empty string was passed, the typecast was changing it to 0. This
produced "LIMIT 0" which returned no results. This must be a bug and not
a feature because there are other params after limit in both
$this->db->limit and $this->db->get.

-<h2>Version 2.0.3</h2>
-<p>Release Date: August 20, 2011</p>
-
-<ul>
-	<li>Security
-		<ul>
-			<li>An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.  <p>An incompatibility in PHP versions &lt; 5.2.3 and MySQL &lt; 5.0.7 with <em>mysql_set_charset()</em> creates a situation where using multi-byte  character sets on these environments may potentially expose a SQL injection attack vector.  Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.</p>  <p class="critical">If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.</p></li>

-<h2>Version 2.0.0</h2>
-<p>Release Date: January 28, 2011<br />
-Hg Tag: v2.0.0</p>
-
-<ul>
-	<li>General changes
-		<ul>
-			<li>PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.</li>
-			<li>Scaffolding, having been deprecated for a number of versions, has been removed.</li>
-			<li>Plugins have been removed, in favor of Helpers.  The CAPTCHA plugin has been converted to a Helper and <a href="./helpers/captcha_helper.html">documented</a>.  The JavaScript calendar plugin was removed due to the ready availability of great JavaScript calendars, particularly with jQuery.</li>
-			<li>Added new special Library type: <a href="./general/drivers.html">Drivers</a>.</li>
-			<li class="reactor">Added full query-string support.  See the config file for details.</li>
-			<li>Moved the application folder outside of the system folder.</li>
-			<li>Moved system/cache and system/logs directories to the application directory.</li>
-			<li>Added routing overrides to the main index.php file, enabling the normal routing to be overridden on a per "index" file basis.</li>
-			<li>Added the ability to set config values (or override config values) directly from data set in the main index.php file.  This allows a single application to be used with multiple front controllers, each having its own config values.</li>
-			<li>Added <kbd>$config['directory_trigger']</kbd> to the config file so that a controller sub-directory can be specified when running _GET strings instead of URI segments.</li>
-			<li>Added ability to set "Package" paths - specific paths where the Loader and Config classes should try to look first for a requested file.  This allows distribution of sub-applications with their own libraries, models, config files, etc. in a single "package" directory.  See the <a href="libraries/loader.html">Loader class</a> documentation for more details.</li>
-			<li>In-development code is now hosted at <a href="http://bitbucket.org/ellislab/codeigniter-reactor/">BitBucket</a>.</li>

-			<li>Added CI_ Prefix to all core classes.</li>
-			<li class="reactor">Package paths can now be set in application/config/autoload.php.</li>
-			<li class="reactor"><a href="libraries/file_uploading.html">Upload library</a> file_name can now be set without an extension, the extension will be taken from the uploaded file instead of the given name.</li>
-			<li class="reactor">In <a href="database/forge.html">Database Forge</a> the name can be omitted from $this->dbforge->modify_column()'s 2nd param if you aren't changing the name.</li>
-			<li class="reactor"><kbd>$config['base_url']</kbd> is now empty by default and will guess what it should be.</li>

-<ul>
-	<li>Libraries
-		<ul>
-			<li>Added a new <a href="libraries/form_validation.html">Form Validation Class</a>.  It simplifies setting rules and field names, supports arrays as field names, allows groups of validation rules to be saved in a config file, and adds some helper functions for use in view files.  <strong>Please note that the old Validation class is now deprecated</strong>. We will leave it in the library folder for some time so that existing applications that use it will not break, but you are encouraged to migrate to the new version.</li>
-			<li>Updated the <a href="libraries/sessions.html">Sessions class</a> so that any custom data being saved gets stored to a database rather than the session cookie (assuming you are using a database to store session data), permitting much more data to be saved.</li>
-			<li>Added the ability to store libraries in subdirectories within either the main "libraries" or the local application "libraries" folder. Please see the <a href="libraries/loader.html">Loader class</a> for more info.</li>

-			<li>Improved the "auto typography" feature and moved it out of the helper into its own <a href="libraries/typography.html">Typography Class</a>.</li>
-			<li>Improved performance and accuracy of <kbd>xss_clean()</kbd>, including reduction of false positives on image/file tests.</li>
-			<li>Improved <a href="./libraries/parser.html">Parser class</a> to allow multiple calls to the parse() function.  The output of each is appended in the output.</li>
-			<li>Added <dfn>max_filename</dfn> option to set a file name length limit in the  <a href="libraries/file_uploading.html">File Upload Class</a>.</li>
-			<li>Added <dfn>set_status_header()</dfn> function to <a href="libraries/output.html">Output class</a>.</li>
-			<li>Modified <a href="libraries/pagination.html">Pagination</a> class to only output the "First" link when the link for page one would not be shown.</li>
-			<li>Added support for mb_strlen in the <a href="libraries/form_validation.html">Form Validation</a> class so that multi-byte languages will calculate string lengths properly.</li>
-		</ul>
-	</li>
-	<li>Database
-		<ul>
-			<li>Improved Active Record class to allow full path column and table names:  hostname.database.table.column.  Also improved the alias handling.</li>
-			<li>Improved how table and column names are escaped and prefixed.  It now honors full path names when adding prefixes and escaping.</li>
-			<li>Added Active Record caching feature to "update" and "delete" functions.</li>
-			<li>Added removal of non-printing control characters in <kbd>escape_str()</kbd> of DB drivers that do not have native PHP escaping mechanisms (mssql, oci8, odbc), to avoid potential SQL errors, and possible sources of SQL injection.</li>
-			<li>Added port support to MySQL, MySQLi, and MS SQL database drivers.</li>

-<li>Added support for a function named <dfn>_output()</dfn>, which when used in your controllers will received the final rendered output from the output class.  More info in the <a href="controllers.html">Controllers</a> page.</li>
-<li>Added several new functions in the <a href="./libraries/uri.html">URI Class</a> to let you retrieve and manipulate URI segments that have been re-routed using the <a href="routing.html">URI Routing</a> feature.

-<li>Deprecated the <dfn>$autoload['core']</dfn> item from the <kbd>autoload.php</kbd> file.  Instead, please now use: <kbd>$autoload['libraries']</kbd></li>

-<ul>
-<li>Added support for <a href="models.html">Models</a>.</li>
-<li>Redesigned the database libraries to support additional RDBMs (Postgres, MySQLi, etc.).</li>
-<li>Redesigned the <a href="./database/active_record.html">Active Record class</a> to enable more varied types of queries with simpler syntax, and advanced features like JOINs.</li>
-<li>Added a feature to the database class that lets you run <a href="./database/call_function.html">custom function calls</a>.</li>
-<li>Added support for <a href="controllers.html">private functions</a> in your controllers.  Any controller function name that starts with an underscore will not be served by a URI request.</li>

-all controller methods are prefixed with <dfn>_ci</dfn> to avoid controller collisions. A list of reserved function names can be <a href="controllers.html">found here</a>.</li>
-<li>Redesigned how the "CI" super object is referenced, depending on whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful way to manage objects that utilizes a bit less resources.</li>

Subject: [PATCH 0074/5397] Changed form_open() to compare $action against
 base_url()

Checking for strpos($action, $CI->config->site_url()) === FALSE causes
CSRF token to not be added in form_open() output. When site_url()'s
first parameter ($uri) is empty, site_url's return value is the base
URL plus the $CI->config->item('index_page') value. form_open() and
CodeIgniter's URI routing do not require index.php to be in the URL, so
any call to form_open() in which the $action parameter does not have
index.php will always return false for the strpos() call.

- *
- * This class is a fallback for servers that are not running PHP greater than

- *
- * This class is based on two scripts:
- *
- * Marcus Campbell's PHP implementation (GNU license)
- * http://www.tecknik.net/sha-1/
- *
- * ...which is based on Paul Johnston's JavaScript version
- * (BSD license). http://pajhome.org.uk/

+#############################
+Upgrading from 2.1.0 to 3.0.0
+#############################
+
+.. note:: These upgrade notes are for a version that is yet to be released.
+
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace all files and directories in your "system" folder and replace
+your index.php file. If any modifications were made to your index.php
+they will need to be made fresh in this new one.
+
+Step 2: Change References to the SHA Library
+============================================
+
+The previously deprecated SHA library has been removed in CodeIgniter 3.0.
+Alter your code to use the native `sha1()` PHP function to generate a sha1 hash.
+
+Additionally, the `sha1()` method in the :doc:`Encryption Library <libraries/encryption>` library has been removed.
+
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.

Subject: [PATCH 0179/5397] added query grouping to Active Record

this is a feature that has been lacking for a very long time. lots of people complained
about it over the years, but it never got added so you'd have to resort to handcrafted
queries when you needed this feature.

This is a port of code from DataMapper, in use since CI 1.6.

+Query grouping
+**************
+
+Query grouping allows you to create groups of WHERE clauses by enclosing them in parentheses. This will allow
+you to create queries with complex WHERE clauses. Nested groups are supported. Example:
+
+	$this->db->select('*')->from('my_table')
+		->group_start()
+			->where('a', 'a')
+			->or_group_start()
+				->where('b', 'b')
+				->where('c', 'c')
+			->group_end()
+		->group_end()
+		->where('d', 'd')
+	->get();
+
+	// Generates:
+	// SELECT * FROM (`my_table`) WHERE ( `a` = 'a' OR ( `b` = 'b' AND `c` = 'c' ) ) AND `d` = 'd'
+
+.. note:: groups need to be balanced, make sure every group_start() is matched by a group_end().
+
+$this->db->group_start()
+========================
+
+Starts a new group by adding an opening parenthesis to the WHERE clause of the query.
+
+$this->db->or_group_start()
+===========================

 complaining this was effecting their performance and having it on by default
 can potentially cause issues with people who don't understand what it does.
 Having it off by default means people are only effected if they want to be,
 which is safer.

 	 -  Added support for 3-length hex color values for wm_font_color and wm_shadow_color properties, as well as validation for them.
 	 -  Class properties wm_font_color, wm_shadow_color and wm_use_drop_shadow are now protected, to avoid breaking the text_watermark() method
 	    if they are set manually after initialization.
+	 -  If property maintain_ratio is set to TRUE, image_reproportion() now doesn't need both width and height to be specified.
    -  Minor speed optimizations and method & property visibility declarations in the Calendar Library.
    -  Removed SHA1 function in the :doc:`Encryption Library <libraries/encryption>`.
    -  Added $config['csrf_regeneration'] to the CSRF protection in the :doc:`Security library <libraries/security>`, which makes token regeneration optional.

Subject: [PATCH 0282/5397] It appears the Security class has been added to the
 system/core folder and is loaded automatically as well. Using
 $this->load->library('security'); in controllers currently returns FALSE, yet
 you might not notice because the Security class is already loaded. I
 discovered this because of a custom Loader class I was using returned an
 error when loading the Security class.

Subject: [PATCH 0510/5397] Added support for Wincache when running CI on
 Windows boxes

Wincache is directly analogous to APC, except with less problems on a Windows environment. Performance wise they are almost identical (for user mode caching at least).

Need to have the Wincache PHP module downloaded from http://www.iis.net/download/wincacheforphp.

 	 -  Added _optimize_table() support for the :doc:`Database Utility Class <database/utilities>` (rebuilds table indexes).
    -  Added a constructor to the DB_result class and moved all driver-specific properties and logic out of the base DB_driver class to allow better abstraction.
    -  Removed limit() and order_by() support for UPDATE and DELETE queries in PostgreSQL driver. Postgres does not support those features.
+   -  Removed protect_identifiers() and renamed _protect_identifiers() to it instead - it was just an alias.

 I know PHP 5.4 just came out, and yes I know PHP 5.3 has lovely features, but
 there are plenty of corporate systems running on CodeIgniter and PHP 5.3
 still is not widely supported enough. CodeIgniter is great for distributed
 applications, and this is the highest we can reasonably go without breaking
 support. PHP 5.3 will most likely happen in another year or so. Fingers
 crossed on that one anyway...

Subject: [PATCH 0609/5397] Fix test errors in Loader_test.php and URI_test.php

Change exceptions from Exception to RuntimeException since PHPUnit 3.6
doesn't like you to expect generic exceptions. The error it gives is:

InvalidArgumentException: You must not expect the generic exception class
travis-ci.org/#!/tiyowan/CodeIgniter/builds/832518

This issue addressed by using exceptions that are more specific.

       get_compiled_insert(), get_compiled_update(), get_compiled_delete().
    -  Taking care of LIKE condition when used with MySQL UPDATE statement.
    -  Adding $escape parameter to the order_by function, this enables ordering by custom fields.
-   -  MySQLi driver now uses mysqli_get_server_info() for server version checking.
-   -  MySQLi driver now supports persistent connections when running on PHP >= 5.3.
+   -  Improved support for the MySQLi driver, including:
+	 -  OOP style of the PHP extension is now used, instead of the procedural aliases.
+	 -  Server version checking is now done via ``mysqli::$server_info`` instead of running an SQL query.
+	 -  Added persistent connections support for PHP >= 5.3.
    -  Added dsn if the group connections in the config use PDO or any driver which need DSN.
    -  Improved PDO database support.
    -  Added Interbase/Firebird database support via the "interbase" driver

 -  Fixed a bug in the :doc:`Session Library <libraries/sessions>` where a PHP E_NOTICE error was triggered by _unserialize() due to results from databases such as MSSQL and Oracle being space-padded on the right.
 -  Fixed a bug (#501) - set_rules() to check if the request method is not 'POST' before aborting, instead of depending on count($_POST) in the :doc:`Form Validation Library <libraries/form_validation>`.
 -  Fixed a bug (#940) - csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.
+-  Fixed a bug in PostgreSQL's escape_str() where it didn't properly escape LIKE wild characters.

 -  Fixed a bug (#940) - csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.

 -  Fixed a bug (#11, #183, #863) - CI_Form_validation::_execute() silently continued to the next rule, if a rule method/function is not found.
 -  Fixed a bug (#1242) - read_dir() in the :doc:`Zip Library <libraries/zip>` wasn't compatible with Windows.
 -  Fixed a bug (#306) - ODBC driver didn't have an _insert_batch() method, which resulted in fatal error being triggered when insert_batch() is used with it.
+-  Fixed a bug in MSSQL and SQLSrv's _truncate() where the TABLE keyword was missing.

 -  Fixed a bug (#1242) - read_dir() in the :doc:`Zip Library <libraries/zip>` wasn't compatible with Windows.
 -  Fixed a bug (#306) - ODBC driver didn't have an _insert_batch() method, which resulted in fatal error being triggered when insert_batch() is used with it.
 -  Fixed a bug in MSSQL and SQLSrv's _truncate() where the TABLE keyword was missing.

Subject: [PATCH 0918/5397] Multiple DB Forge improvements  - Replaced driver
 methods _create_database(), _drop_database(), _drop_table() and
 _rename_table() with properties  - Added defaults for the above mentioned
 platform-specific queries, so that not all drivers need to define them  -
 Improved support for the SQLite, ODBC and PDO drivers

From b457a4001ce2380e97f36b0a983b477c3e31de69 Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@bofh.bg>
Date: Mon, 9 Apr 2012 16:11:56 +0300
Subject: [PATCH 0920/5397] DB Utility improvements  - Replaced driver methods
 _list_databases(), _optimize_table() and _repair_table() with properties  -
 Added defaults for optimize_table() and repair_table() SQL strings (FALSE, as
 those are mostly MySQL-specific)  - Added MSSQL/SQLSRV support for
 optimize_table() (actually rebuilds table indexes)  - Switched public driver
 methods to protected  - Improved CUBRID support for list_databases() as it
 used to only return the currently used database  - Minor speed improvements

 Use of the `$autoload['core']` config array has been deprecated as of CodeIgniter 1.4.1 and is now removed.
 Move any entries that you might have listed there to `$autoload['libraries']` instead.
+
+Step 4: Update your config/database.php
+=======================================
+
+Due to 3.0.0's renaming of Active Record to Query Builder, inside your _config/database.php_, you will
+need to rename the `$active_record` variable to `$query_builder`.
+
+    $active_group = 'default';
+    // $active_record = TRUE;
+    $query_builder = TRUE;

 -  Fixed a bug (#23, #1238) - delete_all() in the `Database Caching Library <database/caching>` used to delete .htaccess and index.html files, which is a potential security risk.
 -  Fixed a bug in :doc:`Trackback Library <libraries/trackback>` method validate_url() where it didn't actually do anything, due to input not being passed by reference.
 -  Fixed a bug (#11, #183, #863) - CI_Form_validation::_execute() silently continued to the next rule, if a rule method/function is not found.
-<<<<<<< HEAD
 -  Fixed a bug (#122) Where routed uri string was being reported incorrectly in sub-directories
 -  Fixed a bug (#1242) - read_dir() in the :doc:`Zip Library <libraries/zip>` wasn't compatible with Windows.
 -  Fixed a bug (#306) - ODBC driver didn't have an _insert_batch() method, which resulted in fatal error being triggered when insert_batch() is used with it.

Subject: [PATCH 1016/5397] Generate better conditions statement on boolean
 field type. Actually boolean field type need TRUE or FALSE value. Common DBMS
 (e.g., MySQL) can substite this value with 1 or 0, but it can't be
 implemented on PostgreSQL. So, its better to use TRUE or FALSE value for
 boolean field type.

Subject: [PATCH 1038/5397] fix backtrace filtering

The backtrace was filtered to remove CI system files,
but the filter was buggy.  It would also filter out
application files which happened to contain the string "system"...
or ALL files, if the application directory is under /system/
(Perhaps the latter comes as a surprise, but it's explicitly
 mentioned in index.php and <http://codeigniter.com/wiki/mod_rewrite>).

Instead, we should test whether the file is underneath BASEPATH
(using realpath() to make sure we have the same sort of slashes).

    -  Added a constructor to the DB_result class and moved all driver-specific properties and logic out of the base DB_driver class to allow better abstraction.
    -  Removed limit() and order_by() support for UPDATE and DELETE queries in PostgreSQL driver. Postgres does not support those features.

Subject: [PATCH 1142/5397] Added support for $_SERVER['CI_ENV'] in index.php
 Remember this is entirely optional, nothing will change if you do not which
 to use Multiple Environments just like right now. If you DO set CI_ENV you
 can manipulate the switch that controls error reporting, etc, so set it to
 "production" on your live site to hide errors from users. If you don't
 require this logic you can remove it, or change it entirely to check
 HTTP_HOST for environment subdomains, or check IP address, etc.

Subject: [PATCH 1152/5397] Direct return from mimes config, instead of using
 global $mimes; Global variables are generally a terrible idea, especially for
 something as simple as this. The mimes.php now returns an array instead of
 just injecting a variable name into the global namespace.

Subject: [PATCH 1155/5397] Added get_mimes() function to
 system/core/Commons.php.The MIMEs array from config/mimes.php is used by
 multiple core classes, libraries and helpers and each of them has implemented
 an own way of getting it, which is not needed and is hard to maintain. This
 also fixes issue #1411

+It returns whatever the database drivers' "execute" function returns.
+That typically is TRUE/FALSE on success or failure for write type queries
+such as INSERT, DELETE or UPDATE statements (which is what it really
+should be used for) and a resource/object on success for queries with
+fetchable results.
+
+::
+

+	{
+		echo "Success!";
+	}
+	else
+	{
+		echo "Query failed!";
+	}
+

+	success, even for write type queries. So take that in mind if
+	you're looking for a boolean value.

Subject: [PATCH 1302/5397] Documentation: remaining PHP "var" declarations
 changed to "public"

Since PHP 4 isn't supported anymore, let's clean up these few
PHP "var" declarations which were remaining in the documentation.

+######################
+Welcome to CodeIgniter
+######################
+
+CodeIgniter is an Application Development Framework - a toolkit - for
+people who build web sites using PHP. Its goal is to enable you to
+develop projects much faster than you could if you were writing code
+from scratch, by providing a rich set of libraries for commonly needed
+tasks, as well as a simple interface and logical structure to access
+these libraries. CodeIgniter lets you creatively focus on your project
+by minimizing the amount of code needed for a given task.
+
+***********************
+Who is CodeIgniter For?
+***********************
+
+CodeIgniter is right for you if:
+
+-  You want a framework with a small footprint.
+-  You need exceptional performance.
+-  You need broad compatibility with standard hosting accounts that run
+   a variety of PHP versions and configurations.
+-  You want a framework that requires nearly zero configuration.
+-  You want a framework that does not require you to use the command
+   line.
+-  You want a framework that does not require you to adhere to
+   restrictive coding rules.

-Welcome to CodeIgniter
-======================
-
-CodeIgniter is an Application Development Framework - a toolkit - for
-people who build web sites using PHP. Its goal is to enable you to
-develop projects much faster than you could if you were writing code
-from scratch, by providing a rich set of libraries for commonly needed
-tasks, as well as a simple interface and logical structure to access
-these libraries. CodeIgniter lets you creatively focus on your project
-by minimizing the amount of code needed for a given task.
-
-Who is CodeIgniter For?
-=======================
-
-CodeIgniter is right for you if:
-
--  You want a framework with a small footprint.
--  You need exceptional performance.
--  You need broad compatibility with standard hosting accounts that run
-   a variety of PHP versions and configurations.
--  You want a framework that requires nearly zero configuration.
--  You want a framework that does not require you to use the command
-   line.
--  You want a framework that does not require you to adhere to
-   restrictive coding rules.
--  You are not interested in large-scale monolithic libraries like PEAR.
--  You do not want to be forced to learn a templating language (although
-   a template parser is optionally available if you desire one).
--  You eschew complexity, favoring simple solutions.
--  You need clear, thorough documentation.

--  Fixed a bug (#697) - A wrong array key was used in the Upload library to check for mime-types.
--  Fixed a bug - form_open() compared $action against site_url() instead of base_url().
--  Fixed a bug - CI_Upload::_file_mime_type() could've failed if mime_content_type() is used for the detection and returns FALSE.

 -  Fixed a bug (#538) - Windows paths were ignored when using the :doc:`Image Manipulation Library <libraries/image_lib>` to create a new file.
 -  Fixed a bug - When database caching was enabled, $this->db->query() checked the cache before binding variables which resulted in cached queries never being found.
 -  Fixed a bug - CSRF cookie value was allowed to be any (non-empty) string before being written to the output, making code injection a risk.
 -  Fixed a bug (#726) - PDO put a 'dbname' argument in it's connection string regardless of the database platform in use, which made it impossible to use SQLite.
--  Fixed a bug - CI_DB_pdo_driver::num_rows() was not returning properly value with SELECT queries, cause it was relying on PDOStatement::rowCount().
--  Fixed a bug (#1059) - CI_Image_lib::clear() was not correctly clearing all necessary object properties, namely width and height.

+###########################
+Contributing to CodeIgniter
+###########################
+
+CodeIgniter is a community driven project and accepts contributions of code
+and documentation from the community. These contributions are made in the form
+of Issues or `Pull Requests <http://help.github.com/send-pull-requests/>`_ on
+the `EllisLab CodeIgniter repository
+<https://github.com/EllisLab/CodeIgniter>`_ on GitHub.
+
+Issues are a quick way to point out a bug. If you find a bug or documentation
+error in CodeIgniter then please check a few things first:
+
+- There is not already an open Issue
+- The issue has already been fixed (check the develop branch, or look for
+  closed Issues)
+- Is it something really obvious that you fix it yourself?
+
+Reporting issues is helpful but an even better approach is to send a Pull
+Request, which is done by "Forking" the main repository and committing to your
+own copy. This will require you to use the version control system called Git.
+
+**********
+Guidelines
+**********
+
+Before we look into how, here are the guidelines. If your Pull Requests fail
+to pass these guidelines it will be declined and you will need to re-submit
+when you’ve made the changes. This might sound a bit tough, but it is required
+for us to maintain quality of the code-base.
+
+PHP Style
+=========
+
+All code must meet the `Style Guide
+<http://codeigniter.com/user_guide/general/styleguide.html>`_, which is
+essentially the `Allman indent style
+<http://en.wikipedia.org/wiki/Indent_style#Allman_style>`_, underscores and
+readable operators. This makes certain that all code is the same format as the
+existing code and means it will be as readable as possible.
+
+Documentation
+=============
+
+If you change anything that requires a change to documentation then you will
+need to add it. New classes, methods, parameters, changing default values, etc
+are all things that will require a change to documentation. The change-log
+must also be updated for every change. Also PHPDoc blocks must be maintained.
+
+Compatibility
+=============
+
+CodeIgniter is compatible with PHP 5.2.4 so all code supplied must stick to
+this requirement. If PHP 5.3 or 5.4 functions or features are used then there
+must be a fallback for PHP 5.2.4.
+
+Branching
+=========
+
+CodeIgniter uses the `Git-Flow
+<http://nvie.com/posts/a-successful-git-branching-model/>`_ branching model
+which requires all pull requests to be sent to the "develop" branch. This is
+where the next planned version will be developed. The "master" branch will
+always contain the latest stable version and is kept clean so a "hotfix" (e.g:
+an emergency security patch) can be applied to master to create a new version,
+without worrying about other features holding it up. For this reason all
+commits need to be made to "develop" and any sent to "master" will be closed
+automatically. If you have multiple changes to submit, please place all
+changes into their own branch on your fork.
+
+One thing at a time: A pull request should only contain one change. That does
+not mean only one commit, but one change - however many commits it took. The
+reason for this is that if you change X and Y but send a pull request for both
+at the same time, we might really want X but disagree with Y, meaning we
+cannot merge the request. Using the Git-Flow branching model you can create
+new branches for both of these features and send two requests.
+
+Signing
+=======
+You must sign your work, certifying that you either wrote the work or
+otherwise have the right to pass it on to an open source project. git makes
+this trivial as you merely have to use `--signoff` on your commits to your
+CodeIgniter fork.
+
+.. code-block:: bash
+
+	git commit --signoff
+
+or simply
+
+.. code-block:: bash
+
+	git commit -s
+
+This will sign your commits with the information setup in your git config, e.g.
+
+	Signed-off-by: John Q Public <john.public@example.com>
+
+If you are using Tower there is a "Sign-Off" checkbox in the commit window. You 
+could even alias git commit to use the -s flag so you don’t have to think about 
+it.
+
+By signing your work in this manner, you certify to a "Developer's Certificate 
+or Origin". The current version of this certificate is in the :doc:`/DCO` file
+in the root of this documentation.

+***************************************************************
+Step 7: Remove usage of (previously) deprecated functionalities
+***************************************************************
+
+In addition to the ``$autoload['core']`` configuration setting, there's a number of other functionalities
+that have been removed in CodeIgniter 3.0.0:
+
+The SHA1 library
+================
+
+The previously deprecated SHA1 library has been removed, alter your code to use PHP's native
+``sha1()`` function to generate a SHA1 hash.
+
+Additionally, the ``sha1()`` method in the :doc:`Encryption Library <../libraries/encryption>` has been removed.
+
+The EXT constant
+================
+
+Usage of the ``EXT`` constant has been deprecated since dropping support for PHP 4. There's no
+longer a need to maintain different filename extensions and in this new CodeIgniter version,
+the ``EXT`` constant has been removed. Use just '.php' instead.
+
+Smiley helper js_insert_smiley()
+================================
+
+:doc:`Smiley Helper <../helpers/smiley_helper>` function ``js_insert_smiley()`` has been deprecated
+since CodeIgniter 1.7.2 and is now removed. You'll need to switch to ``smiley_js()`` instead.
+
+Security helper do_hash()
+=========================
+
+:doc:`Security Helper <../helpers/security_helper>` function ``do_hash()`` is now just an alias for
+PHP's native ``hash()`` function. It is deprecated and scheduled for removal in CodeIgniter 3.1+.
+
+.. note:: This function is still available, but you're strongly encouraged to remove it's usage sooner
+	rather than later.
+
+File helper read_file()
+=======================
+
+:doc:`File Helper <../helpers/file_helper>` function ``read_file()`` is now just an alias for
+PHP's native ``file_get_contents()`` function. It is deprecated and scheduled for removal in
+CodeIgniter 3.1+.
+
+.. note:: This function is still available, but you're strongly encouraged to remove it's usage sooner
+	rather than later.
+
+Pagination library 'anchor_class' setting
+=========================================
+
+The :doc:`Pagination Library <../libraries/pagination>` now supports adding pretty much any HTML
+attribute to your anchors via the 'attributes' configuration setting. This includes passing the
+'class' attribute and using the separate 'anchor_class' setting no longer makes sense.
+As a result of that, the 'anchor_class' setting is now deprecated and scheduled for removal in
+CodeIgniter 3.1+.
+
+.. note:: This setting is still available, but you're strongly encouraged to remove it's usage sooner
+	rather than later.

 	 - Added support for backup() in :doc:`Database Utilities <database/utilities>`.
    -  Added 'dsn' configuration setting for drivers that support DSN strings (PDO, PostgreSQL, Oracle, ODBC, CUBRID).
    -  Improved PDO database support.
-   -  Added Interbase/Firebird database support via the "interbase" driver.
+   -  Added Interbase/Firebird database support via the 'ibase' driver.
    -  Added an optional database name parameter to db_select().
    -  Replaced the _error_message() and _error_number() methods with error(), that returns an array containing the last database error code and message.
    -  Improved version() implementation so that drivers that have a native function to get the version number don't have to be defined in the core DB_driver class.

 	 - Added support for drop_table() in :doc:`Database Forge <database/forge>`.
 	 - Added support for list_databases() in :doc:`Database Utilities <database/utilities>`.
 	 - Generally improved for speed and cleaned up all of its components.
-	 - *Row* result methods now really only fetch only the needed number of rows, instead of depending entirely on result().
 	 - num_rows() is now only called explicitly by the developer and no longer re-executes statements.
    -  Improved support of the SQLite driver, including:
 	 - Added support for replace() in :doc:`Query Builder <database/query_builder>`.

 	 -  Removed method is_numeric() as it exists as a native PHP function and _execute() will find and use that (the 'is_numeric' rule itself is deprecated since 1.6.1).
 	 -  Native PHP functions used as rules can now accept an additional parameter, other than the data itself.
 	 -  Updated set_rules() to accept an array of rules as well as a string.
+	 -  Fields that have empty rules set no longer run through validation (and therefore are not considered erroneous).
    -  Changed the :doc:`Session Library <libraries/sessions>` to select only one row when using database sessions.
    -  Added all_flashdata() method to session class. Returns an associative array of only flashdata.

Subject: [PATCH 1539/5397] Logging should obey error_reporting() setting

If the php error level is not included in the current
error_reporting() setting, we should not log it.

Also, the log_threshold check is redundant, it's
already taken care of by the write_log() method.

+=========

+If you are using PHP >= 5.3 you can use callbacks in place of the normal routing
+rules to process the back-references. Example::

+Session Drivers
+===============
+
+By default, the `Cookie Driver`_ is loaded when a session is initialized.
+However, any valid driver may be selected with the $config['sess_driver']
+line in your config.php file.
+
+The session driver library comes with the cookie and native drivers
+installed, and `Custom Drivers`_ may also be installed by the user.
+
+Typically, only one driver will be used at a time, but CodeIgniter does
+support loading multiple drivers. If a specific valid driver is called, it
+will be automatically loaded. Or, an additional driver may be explicitly
+loaded by calling load_driver()::
+
+	$this->session->load_driver('native');
+
+The Session library keeps track of the most recently selected driver to call
+for driver methods. Normally, session class methods are called directly on
+the parent class, as illustrated above. However, any methods called through
+a specific driver will select that driver before invoking the parent method.
+
+So, alternation between multiple drivers can be achieved by specifying which
+driver to use for each call::
+
+	$this->session->native->set_userdata('foo', 'bar');
+
+	$this->session->cookie->userdata('foo');
+
+	$this->session->native->unset_userdata('foo');
+
+Notice in the previous example that the *native* userdata value 'foo'
+would be set to 'bar', which would NOT be returned by the call for
+the *cookie* userdata 'foo', nor would the *cookie* value be unset by
+the call to unset the *native* 'foo' value. The drivers maintain independent
+sets of values, regardless of key names.
+
+A specific driver may also be explicitly selected for use by pursuant
+methods with the select_driver() call::
+
+	$this->session->select_driver('native');
+
+	$this->session->userdata('item');	// Uses the native driver
+
+Cookie Driver
+-------------
+
+The Cookie driver stores session information for each user as serialized
+(and optionally encrypted) data in a cookie. It can also store the session
+data in a database table for added security, as this permits the session ID
+in the user's cookie to be matched against the stored session ID. By default
+only the cookie is saved. If you choose to use the database option you'll
+need to create the session table as indicated below.
+
+If you have the encryption option enabled, the serialized array will be
+encrypted before being stored in the cookie, making the data highly
+secure and impervious to being read or altered by someone. More info
+regarding encryption can be :doc:`found here <encryption>`, although
+the Session class will take care of initializing and encrypting the data
+automatically.
+
+.. note:: Even if you are not using encrypted sessions, you must set
+	an :doc:`encryption key <./encryption>` in your config file which is used
+	to aid in preventing session data manipulation.
+
+.. note:: Cookies can only hold 4KB of data, so be careful not to exceed
+	the capacity. The encryption process in particular produces a longer
+	data string than the original so keep careful track of how much data you
+	are storing.

-Destroying a Session
-====================
+Native Driver
+-------------
 
-To clear the current session::
+The Native driver relies on native PHP sessions to store data in the
+$_SESSION superglobal array. All stored values continue to be available
+through $_SESSION, but flash- and temp- data items carry special prefixes.
 
-	$this->session->sess_destroy();
+Custom Drivers
+--------------
 
-.. note:: This function should be the last one called, and even flash
-	variables will no longer be available. If you only want some items
-	destroyed and not all, use unset_userdata().
+You may also :doc:`create your own <../general/creating_drivers>` custom
+session drivers. A session driver basically manages an array of name/value
+pairs with some sort of storage mechanism.
 
-Session Preferences
-===================
+To make a new driver, extend CI_Session_driver. Overload the initialize
+method and read or create session data. Then implement a save handler to
+write changed data to storage (sess_save), a destroy handler to remove
+deleted data (sess_destroy), a regenerate handler to make a new session ID,
+and an access handler to expose the data (get_userdata). Your initial class
+might look like::
 
-You'll find the following Session related preferences in your
-application/config/config.php file:
+	class CI_Session_custom extends CI_Session_driver {
+		protected function initialize()
+		{
+			// Read existing session data or create a new one
+		}
+
+		public function sess_save()
+		{
+			// Save current data to storage
+		}
+
+		public function sess_destroy()
+		{
+			// Destroy the current session and clean up storage
+		}
+
+		public function sess_regenerate()
+		{
+			// Create new session ID
+		}
+
+		public function &get_userdata()
+		{
+			// Return a reference to your userdata array
+		}
+	}
+
+Notice that get_userdata() returns a reference so the parent library is
+accessing the same array the driver object is using. This saves memory
+and avoids synchronization issues during usage.
+
+Put your driver in the libraries/Session/drivers folder anywhere in your
+package paths. This includes the application directory, the system directory,
+or any path you add with $CI->load->add_package_path(). Your driver must be
+named CI_Session_<name>, and your filename must be Session_<name>.php,
+preferably also capitalized, such as::
+
+	CI_Session_foo in libraries/Session/drivers/Session_foo.php
+
+Then specify the driver by setting 'sess_driver' in your config.php file or as a
+parameter when loading the CI_Session object::
+
+	$config['sess_driver'] = 'foo';
+
+OR::
+
+	$CI->load->driver('session', array('sess_driver' => 'foo'));
+
+The driver specified by 'sess_driver' is automatically included as a valid
+driver. However, if you want to make a custom driver available as an option
+without making it the initially loaded driver, set 'sess_valid_drivers' in
+your config.php file to an array including your driver name::
+
+	$config['sess_valid_drivers'] = array('sess_driver');

+Step 4: Add new session driver items to your config/config.php
+**************************************************************
+
+With the change from a single Session Library to the new Session Driver, two new config items have been added:
+
+   -  ``$config['sess_driver']`` selects which driver to initially load. Options are:
+       -  'cookie' (the default) for classic CodeIgniter cookie-based sessions
+       -  'native' for native PHP Session support
+       -  the name of a custom driver you have provided (see :doc:`Session Driver <../libraries/sessions>` for more info)
+   -  ``$config['sess_valid_drivers']`` provides an array of additional custom drivers to make available for loading
+
+As the new Session Driver library loads the classic Cookie driver by default and always makes 'cookie' and 'native'
+available as valid drivers, neither of these configuration items are required. However, it is recommended that you
+add them for clarity and ease of configuration in the future.

+structured and organized manner. You could edit fragments of SQL by hand 
+but you would then be responsible for telling other developers that they 
+need to go and run them. You would also have to keep track of which changes 
+need to be run against the production machines next time you deploy.
+
+The database table **migration** tracks which migrations have already been 
+run so all you have to do is update your application files and 
+call **$this->migrate->current()** to work out which migrations should be run. 
+The current version is found in **config/migration.php**.
+
+******************
+Create a Migration
+******************
+
+.. note:: Each Migration is run in numerical order forward or backwards 
+	depending on the method taken. Use a prefix of 3 numbers followed by an 
+	underscore for the filename of your migration.
+	
+This will be the first migration for a new site which has a blog. All 
+migrations go in the folder **application/migrations/** and have names such 
+as: **001_add_blog.php**.::
+
+	defined('BASEPATH') OR exit('No direct script access allowed');
+
+	class Migration_Add_blog extends CI_Migration {
+
+		public function up()
+		{
+			$this->dbforge->add_field(array(
+				'blog_id' => array(
+					'type' => 'INT',
+					'constraint' => 5,
+					'unsigned' => TRUE,
+					'auto_increment' => TRUE
+				),
+				'blog_title' => array(
+					'type' => 'VARCHAR',
+					'constraint' => '100',
+				),
+				'blog_description' => array(
+					'type' => 'TEXT',
+					'null' => TRUE,
+				),
+			));
+			
+			$this->dbforge->create_table('blog');
+		}
+
+		public function down()
+		{
+			$this->dbforge->drop_table('blog');
+		}
+
+Then in **application/config/migration.php** set **$config['migration_version'] = 1;**.
+
+*************
+Usage Example
+*************
+
+In this example some simple code is placed in **application/controllers/migrate.php** 
+to update the schema.::
+
+	$this->load->library('migration');
+
+	if ( ! $this->migration->current())
+	{
+		show_error($this->migration->error_string());
+	}
+
+******************
+Function Reference
+******************
+
+There are five available methods for the Migration class:
+
+-  $this->migration->current();
+-  $this->migration->error_string();
+-  $this->migration->find_migrations();
+-  $this->migration->latest();
+-  $this->migration->version();
+
+$this->migration->current()
+============================
+
+The current migration is whatever is set for **$config['migration_version']** in 
+**application/config/migration.php**.
+
+$this->migration->error_string()
+=================================
+
+This returns a string of errors while performing a migration.
+
+$this->migration->find_migrations()
+====================================
+
+An array of migration filenames are returned that are found in the **migration_path** 
+property.
+
+$this->migration->latest()
+===========================
+
+This works much the same way as current() but instead of looking for 
+the **$config['migration_version']** the Migration class will use the very 
+newest migration found in the filesystem.
+
+$this->migration->version()
+============================
+
+Version can be used to roll back changes or step forwards programmatically to 
+specific versions. It works just like current but ignores **$config['migration_version']**.::
+
+	$this->load->library('migration');
+
+	$this->migration->version(5);
+
+*********************
+Migration Preferences
+*********************
+
+The following is a table of all the config options for migrations.
+
+========================== ====================== ============= =============================================
+Preference                 Default                Options       Description
+========================== ====================== ============= =============================================
+**migration_enabled**      FALSE                  TRUE / FALSE  Enable or disable migrations.
+**migration_path**         APPPATH.'migrations/'  None          The path to your migrations folder.
+**migration_version**      0                      None          The current version your database should use.
+**migration_table**        migrations             None          The table name for storing the shema
+                                                                version number.
+**migration_auto_latest**  FALSE                  TRUE / FALSE  Enable or disable automatically 
+                                                                running migrations.

Subject: [PATCH 1607/5397] Better server test in redirect() of URL helper

"Location" header bugs are specific to IIS; previous test was matching
all HTTP servers under Windows.

This test isn't perfect yet ($_SERVER['SERVER_SOFTWARE'], which
corresponds to the "Server" header of HTTP response, might be missing),
but there is no perfect test.

"Refresh" method makes the window blank for quite a noticeable time,
so let's not affect other servers because of IIS.

+###########################
+Contributing to CodeIgniter
+###########################
+
+CodeIgniter is a community driven project and accepts contributions of code
+and documentation from the community. These contributions are made in the form
+of Issues or `Pull Requests <http://help.github.com/send-pull-requests/>`_ on
+the `EllisLab CodeIgniter repository
+<https://github.com/EllisLab/CodeIgniter>`_ on GitHub.
+
+Issues are a quick way to point out a bug. If you find a bug or documentation
+error in CodeIgniter then please check a few things first:
+
+- There is not already an open Issue
+- The issue has already been fixed (check the develop branch, or look for
+  closed Issues)
+- Is it something really obvious that you fix it yourself?
+
+Reporting issues is helpful but an even better approach is to send a Pull
+Request, which is done by "Forking" the main repository and committing to your
+own copy. This will require you to use the version control system called Git.
+
+**********
+Guidelines
+**********
+
+Before we look into how, here are the guidelines. If your Pull Requests fail
+to pass these guidelines it will be declined and you will need to re-submit
+when you’ve made the changes. This might sound a bit tough, but it is required
+for us to maintain quality of the code-base.
+
+PHP Style
+=========
+
+All code must meet the `Style Guide
+<http://codeigniter.com/user_guide/general/styleguide.html>`_, which is
+essentially the `Allman indent style
+<http://en.wikipedia.org/wiki/Indent_style#Allman_style>`_, underscores and
+readable operators. This makes certain that all code is the same format as the
+existing code and means it will be as readable as possible.
+
+Documentation
+=============
+
+If you change anything that requires a change to documentation then you will
+need to add it. New classes, methods, parameters, changing default values, etc
+are all things that will require a change to documentation. The change-log
+must also be updated for every change. Also PHPDoc blocks must be maintained.
+
+Compatibility
+=============
+
+CodeIgniter is compatible with PHP 5.2.4 so all code supplied must stick to
+this requirement. If PHP 5.3 or 5.4 functions or features are used then there
+must be a fallback for PHP 5.2.4.
+
+Branching
+=========
+
+CodeIgniter uses the `Git-Flow
+<http://nvie.com/posts/a-successful-git-branching-model/>`_ branching model
+which requires all pull requests to be sent to the "develop" branch. This is
+where the next planned version will be developed. The "master" branch will
+always contain the latest stable version and is kept clean so a "hotfix" (e.g:
+an emergency security patch) can be applied to master to create a new version,
+without worrying about other features holding it up. For this reason all
+commits need to be made to "develop" and any sent to "master" will be closed
+automatically. If you have multiple changes to submit, please place all
+changes into their own branch on your fork.
+
+One thing at a time: A pull request should only contain one change. That does
+not mean only one commit, but one change - however many commits it took. The
+reason for this is that if you change X and Y but send a pull request for both
+at the same time, we might really want X but disagree with Y, meaning we
+cannot merge the request. Using the Git-Flow branching model you can create
+new branches for both of these features and send two requests.
+
+Signing
+=======
+You must sign your work, certifying that you either wrote the work or
+otherwise have the right to pass it on to an open source project. git makes
+this trivial as you merely have to use `--signoff` on your commits to your
+CodeIgniter fork.
+
+::
+
+	git commit --signoff
+
+or simply::
+
+	git commit -s
+
+This will sign your commits with the information setup in your git config, e.g.
+
+	Signed-off-by: John Q Public <john.public@example.com>
+
+If you are using Tower there is a "Sign-Off" checkbox in the commit window. You 
+could even alias git commit to use the -s flag so you don’t have to think about 
+it.
+
+By signing your work in this manner, you certify to a "Developer's Certificate 
+or Origin". The current version of this certificate is in the `DCO.txt` file
+in the root of this repository.
+
+
+************
+How-to Guide
+************
+
+There are two ways to make changes, the easy way and the hard way. Either way
+you will need to `create a GitHub account <https://github.com/signup/free>`_.
+
+Easy way GitHub allows in-line editing of files for making simple typo changes
+and quick-fixes. This is not the best way as you are unable to test the code
+works. If you do this you could be introducing syntax errors, etc, but for a
+Git-phobic user this is good for a quick-fix.
+
+Hard way The best way to contribute is to "clone" your fork of CodeIgniter to
+your development area. That sounds like some jargon, but "forking" on GitHub
+means "making a copy of that repo to your account" and "cloning" means
+"copying that code to your environment so you can work on it".
+
+#. Set up Git (Windows, Mac & Linux)
+#. Go to the CodeIgniter repo
+#. Fork it
+#. Clone your CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git
+#. Checkout the "develop" branch At this point you are ready to start making
+   changes. 
+#. Fix existing bugs on the Issue tracker after taking a look to see nobody
+   else is working on them.
+#. Commit the files
+#. Push your develop branch to your fork
+#. Send a pull request http://help.github.com/send-pull-requests/
+
+The Reactor Engineers will now be alerted about the change and at least one of
+the team will respond. If your change fails to meet the guidelines it will be
+bounced, or feedback will be provided to help you improve it.
+
+Once the Reactor Engineer handling your pull request is happy with it they
+will post it to the internal EllisLab discussion area to be double checked by
+the other Engineers and EllisLab developers. If nobody has a problem with the
+change then it will be merged into develop and will be part of the next
+release. Keeping your fork up-to-date
+
+Unlike systems like Subversion, Git can have multiple remotes. A remote is the
+name for a URL of a Git repository. By default your fork will have a remote
+named "origin" which points to your fork, but you can add another remote named
+"codeigniter" which points to git://github.com/EllisLab/CodeIgniter.git. This
+is a read-only remote but you can pull from this develop branch to update your
+own.
+
+If you are using command-line you can do the following:
+
+#. git remote add codeigniter git://github.com/EllisLab/CodeIgniter.git
+#. git pull codeigniter develop
+#. git push origin develop
+
+Now your fork is up to date. This should be done regularly, or before you send
+a pull request at least.

+The Reactor Engineers will now be alerted about the change and at least one of the team will respond. If your change fails to meet the guidelines it will be bounced, or feedback will be provided to help you improve it.
+
+Once the Reactor Engineer handling your pull request is happy with it they will post it to the internal EllisLab discussion area to be double checked by the other Engineers and EllisLab developers. If nobody has a problem with the change then it will be merged into develop and will be part of the next release. Keeping your fork up-to-date
+
+Unlike systems like Subversion, Git can have multiple remotes. A remote is the name for a URL of a Git repository. By default your fork will have a remote named "origin" which points to your fork, but you can add another remote named "codeigniter" which points to `git://github.com/EllisLab/CodeIgniter.git`. This is a read-only remote but you can pull from this develop branch to update your own.
+
+If you are using command-line you can do the following:
+
+1. `git remote add codeigniter git://github.com/EllisLab/CodeIgniter.git`
+2. `git pull codeigniter develop`
+3. `git push origin develop`
+
+Now your fork is up to date. This should be done regularly, or before you send a pull request at least.

    -  :doc:`Query Builder <database/query_builder>` changes include:
 	 - Renamed the Active Record class to Query Builder to remove confusion with the Active Record design pattern.
-	 - Added the ability to insert objects with insert_batch().
-	 - Added new methods that return the SQL string of queries without executing them: get_compiled_select(), get_compiled_insert(), get_compiled_update(), get_compiled_delete().
-	 - Added an optional parameter that allows to disable escaping (useful for custom fields) for methods join(), order_by(), where_in(), or_where_in(), where_not_in(), or_where_not_in().
-	 - Added support for join() with multiple conditions.
-	 - Added support for USING in join().
-	 - Changed limit() to ignore NULL values instead of always casting to integer.
-	 - Changed offset() to ignore empty values instead of always casting to integer.
+	 - Added the ability to insert objects with ``insert_batch()``.

+	 - Changed ``limit()`` to ignore NULL values instead of always casting to integer.
+	 - Changed ``offset()`` to ignore empty values instead of always casting to integer.
    -  Improved support for the MySQLi driver, including:
 	 - OOP style of the PHP extension is now used, instead of the procedural aliases.

+### Test Environment:
+
+The test/Bootstrap.php file establishes global constants such as BASEPATH,
+APPPATH, and VIEWPATH, initializing them to point to VFS locations. The
+test case class employs vfsStream to make a clean virtual filesystem with
+the necessary paths for every individual test.
+
+Within each test case, VFS directory objects are available to use as arguments
+to the VFS convenience functions (see below):
+
+- ci_vfs_root: VFS filesystem root
+- ci_app_root: Application directory
+- ci_base_root: System directory
+- ci_view_root: Views directory
+
+Classes being instantiated for testing are read from the actual filesystem
+by the unit test autoloader, as are mockups created in tests/mocks. If you
+need access to the real system directory, the SYSTEM_PATH constant always
+points to it.
+
+Any other resources which need to be read from the path constants must be
+created or cloned within your test. Functions for doing so are outlined
+below.

+$this->db->replace()
+====================
+
+This method executes a REPLACE statement, which is basically the SQL
+standard for (optional) DELETE + INSERT, using *PRIMARY* and *UNIQUE*
+keys as the determining factor.
+In our case, it will save you from the need to implement complex
+logics with different combinations of  ``select()``, ``update()``,
+``delete()`` and ``insert()`` calls.
+
+Example::
+
+	$data = array(
+		'title' => 'My title',
+		'name'  => 'My Name',
+		'date'  => 'My date'
+	);
+
+	$this->db->replace('table', $data);
+
+	// Executes: REPLACE INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
+
+In the above example, if we assume that the *title* field is our primary
+key, then if a row containing 'My title' as the *title* value, that row
+will be deleted with our new row data replacing it.
+
+Usage of the ``set()`` method is also allowed and all fields are
+automatically escaped, just like with ``insert()``.

From 74ffd17ab06327ca62ddfe28a186cae7ba6bd459 Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@bofh.bg>
Date: Sat, 27 Oct 2012 00:41:03 +0300
Subject: [PATCH 1770/5397] Deprecated form helper function form_prep().

This function has been broken for YEARS and it's value-caching
logic has only introduced various problems. We have html_escape()
since CI 2.1.0 which is a perfect replacement, so it should be
used instead.

Fixes #228 & #1630

Subject: [PATCH 1779/5397] Docblock improvements to the Config library and
 remove CI_Config::_assign_to_config()

Existance of _assign_to_config() is pointless as this method
consists just of a foreach calling CI_Config::set_item() and
is only called by CodeIgniter.php - moved that foreach() in
there instead.

+
+Historically, CodeIgniter has always provided the **:any** wildcard in routing,

+
+However, the **:any** wildcard is actually just an alias for a regular expression
+and used to be executed in that manner as **.+**. This is considered a bug, as it
+also matches the / (forward slash) character, which is the URI segment delimiter
+and that was never the intention. In CodeIgniter 3, the **:any** wildcard will now
+represent **[^/]+**, so that it will not match a forward slash.
+
+There are certainly many developers that have utilized this bug as an actual feature.
+If you're one of them and want to match a forward slash, please use the **.+**

+forward slash ('/'), which would usually represent the delimiter between
+multiple segments.
+For example, if a user accesses a password protected area of your web
+application and you wish to be able to redirect them back to the same
+page after they log in, you may find this example useful::
+
+	$route['login/(.+)'] = 'auth/login/$1';
+
+That will call the auth controller class and its ``login()`` method,
+passing everything contained in the URI after *login/* as a parameter.
+
+For those of you who don't know regular expressions and want to learn
+more about them, `regular-expressions.info <http://www.regular-expressions.info/>`
+might be a good starting point.
 
-You can also mix and match wildcards with regular expressions.

+
+Historically, CodeIgniter has always provided the **:any** wildcard in routing,

+
+However, the **:any** wildcard is actually just an alias for a regular expression
+and used to be executed in that manner as **.+**. This is considered a bug, as it
+also matches the / (forward slash) character, which is the URI segment delimiter
+and that was never the intention. In CodeIgniter 3, the **:any** wildcard will now
+represent **[^/]+**, so that it will not match a forward slash.
+
+There are certainly many developers that have utilized this bug as an actual feature.
+If you're one of them and want to match a forward slash, please use the **.+**
+regular expression::
+
+	(.+)	// matches ANYTHING

For HTTP/1.1 compliance, RFC2616 specifies that both relative
and absolute URI formats must be accepted:

- http://localhost/path/ (absolute)
- /path/ (relative)

Subject: [PATCH 1808/5397] Multiple improvements to the URI class

(thanks to @sourcejedi, PR #1326 for most of the ideas)

 - Renamed _detect_uri() and _parse_cli_args() to _parse_request_uri() and _parse_argv() respectively.
 - Added _parse_query_string() which allows us to detect the URI path from QUERY_STRING much like it is done in _parse_request_uri().

(the above changes also allow for a simpler logic in the case where the *uri_protocol* setting is not set to 'AUTO')

 - Updated application/config/config.php with a better list of the *uri_protocol* options.
 - Added _reset_query_string() to aid in re-processing  from the QUERY_STRING (utilized in _parse_request_uri() and _parse_query_string()).

+********************
+Migration file names
+********************
+
+Each Migration is run in numeric order forward or backwards depending on the

+
+* **Sequential:** each migration is numbered in sequence, starting with **001**.
+  Each number must be three digits, and there must not be any gaps in the
+  sequence. (This was the numbering scheme prior to CodeIgniter 3.0.)
+* **Timestamp:** each migration is numbered using the timestamp when the migration
+  was created, in **YYYYMMDDHHIISS** format (e.g. **20121031100537**). This
+  helps prevent numbering conflicts when working in a team environment, and is
+  the preferred scheme in CodeIgniter 3.0 and later.
+
+The desired style may be selected using the **$config['migration_style']**
+setting in your **migration.php** config file.
+
+Regardless of which numbering style you choose to use, prefix your migration
+files with the migration number followed by an underscore and a descriptive
+name for the migration. For example:

+* **001_add_blog.php** (sequential numbering)

Subject: [PATCH 1816/5397] Changed URI auto-detection to try PATH_INFO first

(thanks to @sourcejedi, PR #1326)

Up until PHP 5.2.4 (which is our new lowest requirement),
there was a bug related to PATH_INFO which made REQUEST_URI
a more reliable choice. This is now no longer the case,
see https://bugs.php.net/bug.php?id=31892 for more details.

Also removed ORIG_PATH_INFO from the suggested alternatives
for uri_protocol in application/config/config.php as it will
not exist in most of PHP's recent versions and is pointless
when you can use PATH_INFO anyway.

Subject: [PATCH 1842/5397] Removed CI_Loader::initialize() and moved its logic
 to the constructor.

That method used to be called by the CI_Controller constructor
and was required because of the possibility to instantiate the
Controller class twice due to 404_override, and so some properties
needed to be reset.

Following the last commit - this is no longer the case.

Subject: [PATCH 1846/5397] Refactored Unit_test in order to remove redundant
 code.

The Unit_test::run method was adding another dimension to the
Unit_test::$results array. For example:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [test_name] => first_test
                    [test_datatype] => integer
                    [res_datatype] => integer
                    [result] => passed
                    [file] => ########################################
                    [line] => 60
                    [notes] => Im expecting this test to pass!
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [test_name] => second_test
                    [test_datatype] => integer
                    [res_datatype] => boolean
                    [result] => failed
                    [file] => #######################################
                    [line] => 65
                    [notes] => Im expecting this to fail.
                )

        )

)

The above unneeded dimension created a need to loop through an array in the
Unit_test::result method if the method was looping through all results.

+or protected and it will not be served via a URL request. For example,
+if you were to have a method like this::
 
 	private function _utility()
 	{
-	  // some code
+		// some code
 	}
 
 Trying to access it via the URL, like this, will not work::
 
 	example.com/index.php/blog/_utility/
 
+.. note:: Prefixing method names with an underscore will also prevent
+	them from being called. This is a legacy feature that is left
+	for backwards-compatibility.

Subject: [PATCH 1854/5397] Refactored DB Forge

- PDO subdrivers are isolated from each other now.
- Added compatibility for pretty much all of the features, for every DB platform.
- Unified the way that stuff works in general.
- Fixes issue #1005.

+============================

+If you want to utilize the PUT, DELETE, PATCH or other exotic request
+methods, they can only be accessed via a special input stream, that
+can only be read once. This isn't as easy as just reading from e.g.
+the ``$_POST`` array, because it will always exist and you can try
+and access multiple variables without caring that you might only have
+one shot at all of the POST data.
+
+CodeIgniter will take care of that for you, and you can access data
+from the **php://input** stream at any time, just by calling the
+``input_stream()`` method::
+
+	$this->input->input_stream('key');
+
+Similar to the methods above, if the requested data is not found, it
+will return NULL and you can also decide whether to run the data
+through ``xss_clean()`` by passing a boolean value as the second
+parameter::
+
+	$this->input->input_stream('key', TRUE); // XSS Clean

Subject: [PATCH 1870/5397] Added function_usable() to common functions

It is now used to check whether dangerous functions like eval() and exec() are available.
It appears that the Suhosin extension (which is becoming popular) terminates script
execution instead of returning e.g. FALSE when it has a function blacklisted.
function_exists() checks are insufficient and our only option is to check the ini
settings here.

Filed an issue here: https://github.com/stefanesser/suhosin/issues/18
... hopefully we'll be able to deal with this in a more elegant way in the future.

(this commit supersedes PR #1809)

 **\'production\'** will turn off these errors. In development mode, it is
 recommended that a value of 'development' is used. More information

Subject: [PATCH 1887/5397] Bring back the AFTER clause for DB Forge
 add_column()

(it was temporarily removed due to multiple inconsistencies with other drivers)

This commit also fixes issue #1988.
Also added support for the FIRST clause (again, MySQL and CUBRID only).

mysql and postgre are started on boot (and therefore don't need manual a start), while
we all know that sqlite is not a service and doesn't need that either.

with "CI_". This is a nity grity change, however it keeps with the

Subject: [PATCH 1967/5397] config->site_url() optimizations

- direct access to config array, instead of item() calls
- the string cast is just in case 'url_suffix' would be set to false or null; the function produces the same results without this cast, but it leads to a robuster code, as false and null are sanitized and skip the suffix insertion code
- altered conditional structure: if no suffix, skip the appending of an empty string to $uri

Subject: [PATCH 1975/5397] Remove CI_DB_oci8_result::data_seek()

It can only call oci_execute() in order to reset the pointer to 0,
the oci8 driver doesn't support setting the pointer.

Due to the result_object(), result_array() and custom_result_object()
calling data_seek() every time prior to fetching the result set, this
only causes the query to be executed twice. All of the three methods
now cast from existing result_object and/or result_array sets, so the
probability to ever need to really fetch the result set again is
practically zero and so this method doesn't bring any benefit.

Subject: [PATCH 1976/5397] Bug fix for relative directory removal

This fixes two bugs:
- for segments that ends with ".." e.g. /user/username../details, this should not be replaced
- current solution only replace double slashes, this solutions removes the infinite number of recurring slashes

Subject: [PATCH 1982/5397] While most of CodeIgniter supports
 protocol-relative URLs, a few URL helpers do not.

Most notably, redirect('//www.facebook.com/aaronadams') led my browser to https://aaronadams.ca/index.php/www.facebook.com/aaronadams.

In this commit, I have fixed the header() helper, along with the anchor() and anchor_popup() helpers, to be compatible with protocol-relative URLs.

Subject: [PATCH 1991/5397] Fix issue #539

Form validation language line keys were not prefixed. They are
now prefixed with 'form_validation_' in order to avoid collisions.
The old keys will still work if a prefixed match is not found, but
are DEPRECATED and will be removed in the next major version.

Also added upgrade notes and changelog entries for the new error
message format from PR #961.

Subject: [PATCH 1994/5397] doc: xss_clean() method is in Security, not Input

The Input doc does talk about xss filtering, but they refer you to Security for details, which is where the function is actually defined.  It gives more detail about what the function is supposed to do, and avoids some irrelevance.

It's probably not a big deal; it just looks wrong.  It _might_ have been responsible for [confusion](http://stackoverflow.com/questions/13570522/this-input-xss-cleandata-giving-fatal-error-with-codeigniter) sometimes.

 modifying `_uri_assoc()` to (1) not force a specific list of valid options
 for `$which`, and (2) build the `$segment_array` and `$total_segments`
 dynamically regardless of the contents of `$which`.

Subject: [PATCH 2019/5397] Fixed normalization of headers under Apache

The existing header normalization routine converts headers provided by Apache (that is, with `-` in the name instead of `_`)
to all lowercase, with the exception of the first character.  This is different from the expected result, wherein each word
of the header is capitalized.  For example, `CONTENT-LENGTH` would normalize to `Content-length` instead of the expected
`Content-Length`.  The reason for this is that the existing code is only converting underscores to spaces, and leaving hyphens
untouched.  The fix is to replace hyphens with spaces as well before passing the result through `ucwords()`.

That fix is included here.

Subject: [PATCH 2030/5397] Slight performance improvement by moving some class
 property initialization to the class property declarations rather than
 setting them in the constructor. Subclasses can always override in their own
 constructor if they wish to. Is there a reason why it was done the way it was
 done? A policy that I am not aware of?

    -  ``db_set_charset()`` now only requires one parameter (collation was only needed due to legacy support for MySQL versions prior to 5.1).
+   -  ``db_select()`` will now always (if required by the driver) be called by ``db_connect()`` / ``db_pconnect()`` instead of only when initializing.
    -  Replaced the ``_error_message()`` and ``_error_number()`` methods with ``error()``, which returns an array containing the last database error code and message.
    -  Improved ``version()`` implementation so that drivers that have a native function to get the version number don't have to be defined in the core ``DB_driver`` class.

Subject: [PATCH 2059/5397] Updated all cases of exit() to return a valid code

Specific codes are as follows, but can easily be changed if a different order/breakdown makes more sense:

- 0: Success; everything executed as planned
- 1: Configuration Error; something is wrong with/in the configuration file(s)
- 2: Class Not Found; what it says
- 3: Driver Method Unsupported; the method you're trying to use on a Driver doesn't exist
- 4: File Not Found; 404 error
- 5: Database Error; something is broken in the database somewhere
- 6: Invalid Input; the user attempted to submit a request with invlaid characters in 1+ key names
7 through 26 are reserved for future use
- 27: Generic Error; generated by show_error() when the status code is >= 100
28 through 127 are errors generated by user applications, normally by using show_error() with a status code below 100
128 through 254 should not be used by applications, as they are reserved by system-level functions
- 255: PHP Fatal Error; automatically generated by PHP for fatal errors, and therefore not allowed for our use

Status codes below 100 are shifted up by 28 to place them in the user error range.  It may make more sense to have these codes
left alone and instead shift the CI errors into the 101 through 127 space, but that's not what I opted for here.

It would probably also be a good idea to replace the hard-coded numbers with constants or some such, but I was in a bit of a
hurry when I made these changes, so I didn't look around for the best place to do this.  With proper guidance, I could
easily amend this commit with another that uses such constant values.

Subject: [PATCH 2068/5397] Fix auto_link() for the Nth time

 - anchor() is for local links and breaks ones that don't have a protocol prefix
 - Allow :// links (no actual protocol specified)
 - Further simplified the URL regular expression

For example: If you clear this string "%%3f3f" according to the $bad array will fail. The result will be "%3f"
Because str_replace() replaces left to right.

+(meaning that the first letter of the class name must be a capital). For example,
+if you have the following library file:

On the first list_fields call, the field pointer is moved to the end
of the list of fields. This change ensures that the pointer is
positioned at the start of the field list before grabbing the names.

MIME-Version: 1.0

Updated Log.php so that a developer can extend it and change the log file extension.

It makes sense to default to .php when logs are in the public web folder.  It would be nice if a developer moves the log file path we have the option to use a standard extension like .log

 Bug fixes for 3.0
 ------------------
 
+-  Fixed a bug (#2255, #2256) where ``smtp_timeout`` was not being applied to read and writes for the socket.
 -  Fixed a bug where ``unlink()`` raised an error if cache file did not exist when you try to delete it.
 -  Fixed a bug (#181) where a mis-spelling was in the form validation language file.
 -  Fixed a bug (#159, #163) that mishandled Query Builder nested transactions because _trans_depth was not getting incremented.

Subject: [PATCH 2165/5397] Updated exit codes as constant values

Re-allocated exit status codes according to three references, which follow:

BSD sysexits.h:http://www.gsp.com/cgi-bin/man.cgi?section=3&topic=sysexits
GNU recomendations:http://www.gnu.org/software/libc/manual/html_node/Exit-Status.html
Bash scripting:http://tldp.org/LDP/abs/html/exitcodes.html

The GNU recommendations stem from and expand upon the standard C/C++ library (stdlibc)
definitions, while also suggesting some best-practice conventions which happen to prevent
exit status code collisions with bash, and probably other shells.

The re-allocated codes are now mapped to constant values, set in *application/config/constants.php*,
and used throughout the CodeIgniter core.  They would additionally be used in *index.php*,
but the constants file hasn't been loaded at that point, so the integer values are used
instead, and a comment follows each such use with amplifying information on why that
particular value was selected.

Finally, the errors documentation has been updated accordingly.

-code contains an alternative method when the function is not available,
-or you implicitly document that your add-on requires said PHP libraries.
-
-Class and File Names using Common Words
-=======================================
-
-When your class or filename is a common word, or might quite likely be
-identically named in another PHP script, provide a unique prefix to help
-prevent collision. Always realize that your end users may be running
-other add-ons or third party PHP scripts. Choose a prefix that is unique

-	class Pre_xml		ext.pre_xml.php
-	class Pre_import	mod.pre_import.php
-
-Database Table Names
-====================
-
-Any tables that your add-on might use must use the 'exp\_' prefix,
-followed by a prefix uniquely identifying you as the developer or
-company, and then a short descriptive table name. You do not need to be
-concerned about the database prefix being used on the user's
-installation, as CodeIgniter's database class will automatically convert
-'exp\_' to what is actually being used.
-
-**INCORRECT**::
-

-	exp_email_addresses	// missing unique prefix
-

-
-	exp_pre_email_addresses
+CodeIgniter requires a minimum PHP version of 5.2.4. Your code must either
+be compatible with this minimum requirement, provide a suitable fallback,
+or be an optional feature that dies quietly without affecting a user's
+application.
 
-.. note:: Be mindful that MySQL has a limit of 64 characters for table
-	names. This should not be an issue as table names that would exceed this
-	would likely have unreasonable names. For instance, the following table
-	name exceeds this limitation by one character. Silly, no?

+to be installed unless your code contains an alternative method when the
+function is not available.

From 50dfe0175df02fe4aa243757bdf1b42fb9fc3169 Mon Sep 17 00:00:00 2001
From: Daniel Hunsaker <danhunsaker@gmail.com>
Date: Mon, 4 Mar 2013 02:05:20 -0700
Subject: [PATCH 2176/5397] Updated in accordance with feedback from @narfbg

- Removed commented lists of constants from the three reference conventions,
  replacing each with the URLs at which more information can be found.
- Renamed a few constants to more closely reflect CodeIgniter conventions.
- Modified a couple of lines which were in violation of the CI Style Guide.

       - Added support (auto-detection) for HTTP/1.1 response code 303 in :php:func:`redirect()`.
       - Changed :php:func:`redirect()` to only choose the **refresh** method only on IIS servers, instead of all servers on Windows (when **auto** is used).
       - Changed :php:func:`anchor()`, :php:func:`anchor_popup()`, and :php:func:`redirect()` to support protocol-relative URLs (e.g. *//ellislab.com/codeigniter*).
+      - Added an optional second parameter to both :php:func:`base_url()` and :php:func:`site_url()` that allows enforcing of a protocol different than the one in the *base_url* configuration setting.

+**************************************
+Step 2: Update your classes file names
+**************************************
+
+Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers
+and models) must be named in a Ucfirst-like manner or in other words - they must
+start with a capital letter.
+
+For example, if you have the following library file:
+
+	application/libraries/mylibrary.php
+
+... then you'll have to rename it to:
+
+	application/libraries/Mylibrary.php
+
+The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
+own libraries and core classes.
+
+	application/libraries/MY_email.php
+	application/core/MY_log.php
+
+The above files should respectively be renamed to the following:
+
+	application/libraries/MY_Email.php
+	application/core/MY_Log.php
+
+Controllers:
+
+	application/controllers/welcome.php	->	application/controllers/Welcome.php
+
+Models:
+
+	application/models/misc_model.php	->	application/models/Misc_model.php
+
+Please note that this DOES NOT affect directories, configuration files, views,
+helpers, hooks and anything else - it is only applied to classes.
+
+You must now follow just one simple rule - class names in Ucfirst and everything else
+in lowercase.

+======================================
+
+The ``is_loaded()`` method allows you to check if a class has already
+been loaded or not.
+
+.. note:: The word "class" here refers to libraries and drivers.
+
+If the requested class has been loaded, the method returns its assigned
+name in the CI Super-object and FALSE if it's not::
+
+	$this->load->library('form_validation');
+	$this->load->is_loaded('Form_validation');	// returns 'form_validation'
+
+	$this->load->is_loaded('Nonexistent_library');	// returns FALSE
+
+.. important:: If you have more than one instance of a class (assigned to
+	different properties), then the first one will be returned.

Subject: [PATCH 2399/5397] Cache Driver - Backup Never Loaded The condition
 that checks to see if the backup driver input is valid was prefixing the
 input with "cache_". Since the valid driver values don't have this prefix,
 the condition was always returning FALSE and the backup drivers were never
 being loaded. I've removed the prefix in the condition and added a debug log
 message for when the backup driver is used.

+Overriding Word Wrapping
+========================
 
-$this->email->from()
---------------------
+If you have word wrapping enabled (recommended to comply with RFC 822)
+and you have a very long link in your email it can get wrapped too,
+causing it to become un-clickable by the person receiving it.
+CodeIgniter lets you manually override word wrapping within part of your
+message like this::
 
-Sets the email address and name of the person sending the email::
+	The text of your email that
+	gets wrapped normally.
 
-	$this->email->from('you@example.com', 'Your Name');
+	{unwrap}http://example.com/a_long_link_that_should_not_be_wrapped.html{/unwrap}
 
-You can also set a Return-Path, to help redirect undelivered mail::
+	More text that will be
+	wrapped normally.
 
-	$this->email->from('you@example.com', 'Your Name', 'returned_emails@example.com');
-	
-.. note:: Return-Path can't be used if you've configured
-	'smtp' as your protocol.
 
-$this->email->reply_to()
-------------------------
+Place the item you do not want word-wrapped between: {unwrap} {/unwrap}
 
-Sets the reply-to address. If the information is not provided the
-information in the "from" method is used. Example::
+***************
+Class Reference
+***************
 
-	$this->email->reply_to('you@example.com', 'Your Name');
+.. class:: CI_Email
 
-$this->email->to()
-------------------
+	.. method:: from($from[, $name = ''[, $return_path = NULL]])
 
-Sets the email address(s) of the recipient(s). Can be a single email, a
-comma-delimited list or an array::
+		:param string $from: "From" email address
+		:param string $name: "From" display name
+		:param string $return_path: optional email address to redirect undelivered email
+		:returns: CI_Email object for method chaining
 
-	$this->email->to('someone@example.com');
+		Sets the email address and name of the person sending the email::
 
-::
+			$this->email->from('you@example.com', 'Your Name');
 
-	$this->email->to('one@example.com, two@example.com, three@example.com');
+		You can also set a Return-Path, to help redirect undelivered mail::
 
-::
+			$this->email->from('you@example.com', 'Your Name', 'returned_emails@example.com');
 
-	$list = array('one@example.com', 'two@example.com', 'three@example.com');

+		:param string $name: display name for reply email address
+		:returns: CI_Email object for method chaining
 
-$this->email->bcc()
--------------------
+		Sets the reply-to address. If the information is not provided the
+		information in the :meth:from method is used. Example::
 
-Sets the BCC email address(s). Just like the "to", can be a single
-email, a comma-delimited list or an array.
+			$this->email->reply_to('you@example.com', 'Your Name');

-This is an optional message string which can be used if you send HTML
-formatted email. It lets you specify an alternative message with no HTML

-$this->email->clear()
----------------------
+		Sets the CC email address(s). Just like the "to", can be a single
+		email, a comma-delimited list or an array.
 
-Initializes all the email variables to an empty state. This method is
-intended for use if you run the email sending method in a loop,

-$this->email->attach()
-----------------------
+		:param string $body: email body
+		:returns: CI_Email object for method chaining
 
-Enables you to send an attachment. Put the file path/name in the first
-parameter. Note: Use a file path, not a URL. For multiple attachments
-use the method multiple times. For example::
+		Sets the email message body::
 
-	$this->email->attach('/path/to/photo1.jpg');
-	$this->email->attach('/path/to/photo2.jpg');
-	$this->email->attach('/path/to/photo3.jpg');
+			$this->email->message('This is my message');
 
-To use the default disposition (attachment), leave the second parameter blank,
-otherwise use a custom disposition::
 
-	$this->email->attach('image.jpg', 'inline');
+	.. method:: set_alt_message([$str = ''])
 
-If you'd like to use a custom file name, you can use the third paramater::
+		:param string $str: alternate email body
+		:returns: CI_Email object for method chaining
 
-	$this->email->attach('filename.pdf', 'attachment', 'report.pdf');
+		Sets the alternative email message body::
 
-If you need to use a buffer string instead of a real - physical - file you can
-use the first parameter as buffer, the third parameter as file name and the fourth
-parameter as mime-type::
+			$this->email->set_alt_message('This is the alternative message');
 
-	$this->email->attach($buffer, 'attachment', 'report.pdf', 'application/pdf');
+		This is an optional message string which can be used if you send
+		HTML formatted email. It lets you specify an alternative message
+		with no HTML formatting which is added to the header string for
+		people who do not accept HTML email. If you do not set your own
+		message CodeIgniter will extract the message from your HTML email
+		and strip the tags.
 
-$this->email->print_debugger()
-------------------------------
 
-Returns a string containing any server messages, the email headers, and
-the email messsage. Useful for debugging.
+	.. method:: set_header($header, $value)
 
-You can optionally specify which parts of the message should be printed.
-Valid options are: **headers**, **subject**, **body**.
+		:param string $header: header name
+		:param string $value: header value
+		:returns: void
 
-Example::
+		Appends additional headers to the e-mail::
 
-	// You need to pass FALSE while sending in order for the email data
-	// to not be cleared - if that happens, print_debugger() would have
-	// nothing to output.
-	$this->email->send(FALSE);
+			$this->email->set_header('Header1', 'Value1');
+			$this->email->set_header('Header2', 'Value2');
 
-	// Will only print the email headers, excluding the message subject and body
-	$this->email->print_debugger(array('headers'));
 
-.. note:: By default, all of the raw data will be printed.
+	.. method:: clear([$clear_attachments = FALSE])
 
-Overriding Word Wrapping
-========================
+		:param bool $clear_attachments: whether or not to clear attachments
 
-If you have word wrapping enabled (recommended to comply with RFC 822)
-and you have a very long link in your email it can get wrapped too,
-causing it to become un-clickable by the person receiving it.
-CodeIgniter lets you manually override word wrapping within part of your
-message like this::
+		Initializes all the email variables to an empty state. This method
+		is intended for use if you run the email sending method in a loop,
+		permitting the data to be reset between cycles.
 
-	The text of your email that
-	gets wrapped normally.
+		::
 
-	{unwrap}http://example.com/a_long_link_that_should_not_be_wrapped.html{/unwrap}
+			foreach ($list as $name => $address)
+			{
+				$this->email->clear();
 
-	More text that will be
-	wrapped normally.
-	
+				$this->email->to($address);
+				$this->email->from('your@example.com');
+				$this->email->subject('Here is your info '.$name);
+				$this->email->message('Hi '.$name.' Here is the info you requested.');
+				$this->email->send();
+			}
+
+		If you set the parameter to TRUE any attachments will be cleared as
+		well::
+
+			$this->email->clear(TRUE);
+
+
+	.. method:: send([$auto_clear = TRUE])
+
+		:param bool $auto_clear: Whether to :meth:clear automatically
+		:returns: bool
+
+		The Email sending method. Returns boolean TRUE or FALSE based on
+		success or failure, enabling it to be used conditionally::
+
+			if ( ! $this->email->send())
+			{
+				// Generate error
+			}
+
+		This method will automatically clear all parameters if the request was
+		successful. To stop this behaviour pass FALSE::
+
+		 	if ($this->email->send(FALSE))
+		 	{
+		 		// Parameters won't be cleared
+		 	}
+
+		.. note:: In order to use the ``print_debugger()`` method, you need
+			to avoid clearing the email parameters.
+
+
+	.. method:: attach($filename[, $disposition = ''[, $newname = NULL[, $mime = '']]])
+
+		:param string $filename: name of the file
+		:param string $disposition: 'disposition' of the attachment. Most
+			email clients make their own decision regardless of the MIME
+			specification used here. https://www.iana.org/assignments/cont-disp/cont-disp.xhtml
+		:param string $newname: custom name to use for the file in the email
+		:param string $mime: MIME type to use (useful for buffered data)
+		:returns: CI_Email object for method chaining
+
+		Enables you to send an attachment. Put the file path/name in the first
+		parameter. Note: Use a file path, not a URL. For multiple attachments
+		use the method multiple times. For example::
+
+			$this->email->attach('/path/to/photo1.jpg');
+			$this->email->attach('/path/to/photo2.jpg');
+			$this->email->attach('/path/to/photo3.jpg');
+
+		To use the default disposition (attachment), leave the second parameter blank,
+		otherwise use a custom disposition::
+
+			$this->email->attach('image.jpg', 'inline');
+
+		If you'd like to use a custom file name, you can use the third paramater::
+
+			$this->email->attach('filename.pdf', 'attachment', 'report.pdf');
+
+		If you need to use a buffer string instead of a real - physical - file you can
+		use the first parameter as buffer, the third parameter as file name and the fourth
+		parameter as mime-type::
+
+			$this->email->attach($buffer, 'attachment', 'report.pdf', 'application/pdf');
+
+
+	.. method:: print_debugger([$include = array('headers', 'subject', 'body')])
+
+		:param array $include: Which parts of the message to print out
+		:returns: string
+
+		Returns a string containing any server messages, the email headers, and
+		the email messsage. Useful for debugging.
+
+		You can optionally specify which parts of the message should be printed.
+		Valid options are: **headers**, **subject**, **body**.
+
+		Example::
+
+			// You need to pass FALSE while sending in order for the email data
+			// to not be cleared - if that happens, print_debugger() would have
+			// nothing to output.
+			$this->email->send(FALSE);
+
+			// Will only print the email headers, excluding the message subject and body
+			$this->email->print_debugger(array('headers'));

Subject: [PATCH 2432/5397] Add a changelog entry for PR #2590 and further
 optimize log_message()

CI_Log::write_log() already checks the log threshold, so there's no point in doing it in log_message() as well.

-$this->zip->add_data()
-=======================
+.. class:: CI_Zip
 
-Permits you to add data to the Zip archive. The first parameter must
-contain the name you would like given to the file, the second parameter
-must contain the file data as a string::
+	.. method:: add_data($filepath[, $data = NULL])
 
-	$name = 'my_bio.txt';
-	$data = 'I was born in an elevator...';
+		:param mixed $filepath: a single file path or an array of file => data pairs
+		:param array $data: single file contents
+		:returns: void
 
-	$this->zip->add_data($name, $data);
+		Adds data to the Zip archive. Can work both in single and multiple files mode.
 
-You are allowed multiple calls to this function in order to add several
-files to your archive. Example::
+		When adding a single file, the first parameter must contain the name you would like given to the file and the second must contain the file contents::
 
-	$name = 'mydata1.txt';
-	$data = 'A Data String!';
-	$this->zip->add_data($name, $data);
+			$name = 'mydata1.txt';
+			$data = 'A Data String!';
+			$this->zip->add_data($name, $data);
 
-	$name = 'mydata2.txt';
-	$data = 'Another Data String!';
-	$this->zip->add_data($name, $data);
+			$name = 'mydata2.txt';
+			$data = 'Another Data String!';
+			$this->zip->add_data($name, $data);
+			
+		When adding multiple files, the first parameter must contain *file => contents* pairs and the second parameter is ignored::
 
-Or you can pass multiple files using an array::
+			$data = array(
+				'mydata1.txt' => 'A Data String!',
+				'mydata2.txt' => 'Another Data String!'
+			);
 
-	$data = array(
-	                'mydata1.txt' => 'A Data String!',
-	                'mydata2.txt' => 'Another Data String!'
-	            );
+			$this->zip->add_data($data);
 
-	$this->zip->add_data($data);
+		If you would like your compressed data organized into sub-directories, simply include the path as part of the filename(s)::
 
-	$this->zip->download('my_backup.zip');
+			$name = 'personal/my_bio.txt';
+			$data = 'I was born in an elevator...';

-$this->zip->read_dir()
-=======================
+	.. method:: read_dir($path[, $preserve_filepath = TRUE[, $root_path = NULL]])
 
-Permits you to compress a folder (and its contents) that already exists
-somewhere on your server. Supply a file path to the directory and the
-zip class will recursively read it and recreate it as a Zip archive. All
-files contained within the supplied path will be encoded, as will any
-sub-folders contained within it. Example::
+		:param string $path: path to directory
+		:param bool $preserve_filepath: whether to maintain the original path
+		:param string $root_path: part of the path to exclude from the archive directory

-	$path = '/path/to/your/directory/';
+		Permits you to compress a directory (and its contents) that already exists somewhere on your server.
+		Supply a path to the directory and the zip class will recursively read and recreate it as a Zip archive.
+		All files contained within the supplied path will be encoded, as will any sub-directories contained within it. Example::
 
-	$this->zip->read_dir($path); 
+			$path = '/path/to/your/directory/';
 
-	// Download the file to your desktop. Name it "my_backup.zip"
-	$this->zip->download('my_backup.zip');
+			$this->zip->read_dir($path); 
 
-By default the Zip archive will place all directories listed in the
-first parameter inside the zip. If you want the tree preceding the
-target folder to be ignored you can pass FALSE (boolean) in the second
-parameter. Example::
+			// Download the file to your desktop. Name it "my_backup.zip"
+			$this->zip->download('my_backup.zip');
 
-	$path = '/path/to/your/directory/';
+		By default the Zip archive will place all directories listed in the first parameter inside the zip.
+		If you want the tree preceding the target directory to be ignored you can pass FALSE (boolean) in the second parameter. Example::
 
-	$this->zip->read_dir($path, FALSE);
+			$path = '/path/to/your/directory/';
 
-This will create a ZIP with the folder "directory" inside, then all
-sub-folders stored correctly inside that, but will not include the
-folders /path/to/your.
+			$this->zip->read_dir($path, FALSE);
 
-$this->zip->archive()
-=====================
+		This will create a ZIP with a directory named "directory" inside, then all sub-directories stored correctly inside that, but will not include the
+		*/path/to/your* part of the path.
 
-Writes the Zip-encoded file to a directory on your server. Submit a
-valid server path ending in the file name. Make sure the directory is
-writable (666 or 777 is usually OK). Example::
+	.. method:: archive($filepath)
 
-	$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip
+		:param string $filepath: path to target zip archive
+		:returns: bool
 
-$this->zip->download()
-======================
+		Writes the Zip-encoded file to a directory on your server. Submit a valid server path ending in the file name.
+		Make sure the directory is writable (660 or 666 is usually OK). Example::
 
-Causes the Zip file to be downloaded from your server. The function must
-be passed the name you would like the zip file called. Example::
+			$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip
 
-	$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"
+	.. method:: download($filename = 'backup.zip')
 
-.. note:: Do not display any data in the controller in which you call
-	this function since it sends various server headers that cause the
-	download to happen and the file to be treated as binary.
+		:param string $filename: the archive file name
+		:returns: void
 
-$this->zip->get_zip()
-======================
+		Causes the Zip file to be downloaded from your server. You must pass the name you would like the zip file called. Example::
 
-Returns the Zip-compressed file data. Generally you will not need this
-function unless you want to do something unique with the data. Example::
+			$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"
 
-	$name = 'my_bio.txt';
-	$data = 'I was born in an elevator...';
+		.. note:: Do not display any data in the controller in which you call
+			this method since it sends various server headers that cause the
+			download to happen and the file to be treated as binary.
 
-	$this->zip->add_data($name, $data);
+	.. method:: get_zip()
 
-	$zip_file = $this->zip->get_zip();
+		:returns: string
 
-$this->zip->clear_data()
-=========================
+		Returns the Zip-compressed file data. Generally you will not need this method unless you want to do something unique with the data. Example::
 
-The Zip class caches your zip data so that it doesn't need to recompile
-the Zip archive for each function you use above. If, however, you need
-to create multiple Zips, each with different data, you can clear the
-cache between calls. Example::
+			$name = 'my_bio.txt';
+			$data = 'I was born in an elevator...';
 
-	$name = 'my_bio.txt';
-	$data = 'I was born in an elevator...';
+			$this->zip->add_data($name, $data);
 
-	$this->zip->add_data($name, $data);
-	$zip_file = $this->zip->get_zip();
+			$zip_file = $this->zip->get_zip();
+
+	.. method:: clear_data()
+
+		:returns: void
+

--  Surrounds paragraphs within <p></p> (looks for double line breaks to
-   identify paragraphs).
--  Single line breaks are converted to <br />, except those that appear
-   within <pre> tags.
--  Block level elements, like <div> tags, are not wrapped within
-   paragraphs, but their contained text is if it contains paragraphs.
--  Quotes are converted to correctly facing curly quote entities, except
-   those that appear within tags.
--  Apostrophes are converted to curly apostrophe entities.
--  Double dashes (either like -- this or like--this) are converted to
-   em—dashes.
--  Three consecutive periods either preceding or following a word are
-   converted to ellipsis…
--  Double spaces following sentences are converted to non-breaking
-   spaces to mimic double spacing.
+.. class:: CI_Typography
 
-Usage example::
+	.. attribute:: $protect_braced_quotes = FALSE
 
-	$string = $this->typography->auto_typography($string);
+		When using the Typography library in conjunction with the :doc:`Template Parser library <../parser>`
+		it can often be desirable to protect single and double quotes within curly braces.
+		To enable this, set the ``protect_braced_quotes`` class property to TRUE.
 
-Parameters
-----------
+		Usage example::
 
-There is one optional parameters that determines whether the parser
-should reduce more then two consecutive line breaks down to two. Use
-boolean TRUE or FALSE.
+			$this->load->library('typography');
+			$this->typography->protect_braced_quotes = TRUE;
 
-By default the parser does not reduce line breaks. In other words, if no
-parameters are submitted, it is the same as doing this::
+	.. method auto_typography($str[, $reduce_linebreaks = FALSE])
 
-	$string = $this->typography->auto_typography($string, FALSE);
+		:param string $str: input string
+		:param bool $reduce_linebreaks: whether to reduce consequitive linebreaks
+		:returns: string
 
-.. note:: Typographic formatting can be processor intensive,
-	particularly if you have a lot of content being formatted. If you choose
-	to use this function you may want to consider :doc:`caching <../general/caching>`
-	your pages.

+		 -  Three consecutive periods either preceding or following a word are converted to ellipsis (…).
+		 -  Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.
 
-This function is similar to the auto_typography function above, except
-that it only does character conversion:

--  Quotes are converted to correctly facing curly quote entities, except
-   those that appear within tags.
--  Apostrophes are converted to curly apostrophe entities.

+			$string = $this->typography->auto_typography($string);
 
-Usage example::
+		There is one optional parameter that determines whether the parser should reduce more then two consecutive line breaks down to two.
+		Pass boolean TRUE to enable reducing line breaks::

Subject: [PATCH 2525/5397] Removed extra from $name, since it does not follow
 the format of other form_ helpers. Form helpers use $extra as a string. On
 the form_input for example, the $extra is a string but placing extra in the
 first parameter results in an attribute on the resulting element called
 'extra', whereas the drop down it does not. $extra is now passed along as
 works just as all other form_ methods do.

       -  Changed ``site_url()`` method  to accept an array as well.
       -  Removed internal method ``_assign_to_config()`` and moved its implementation to *CodeIgniter.php* instead.
       -  ``item()`` now returns NULL instead of FALSE when the required config item doesn't exist.
+      -  Added an optional second parameter to both ``base_url()`` and ``site_url()`` that allows enforcing of a protocol different than the one in the *base_url* configuration setting.

 Redis Caching
 =============
 
+Redis is an in-memory key-value store which can operate in LRU cache mode. 
+To use it, you need Redis server and any Redis PHP extension, e.g. this one
+`https://github.com/nicolasff/phpredis <https://github.com/nicolasff/phpredis>`_.
+
+Config options to connect to redis server must be stored in the application/config/redis.php file.
+Available options are::
+	
+	$config['socket_type'] = 'tcp'; //`tcp` or `unix`
+	$config['socket'] = '/var/run/redis.sock'; // in case of `unix` socket type
+	$config['host'] = '127.0.0.1';
+	$config['password'] = NULL;
+	$config['port'] = 6379;
+	$config['timeout'] = 0;
+
 All of the methods listed above can be accessed without passing a
 specific adapter to the driver loader as follows::
 
 	$this->load->driver('cache');
 	$this->cache->redis->save('foo', 'bar', 10);
 
-.. important:: Redis may require one or more of the following options:
-	**host**, **post**, **timeout**, **password**.
-
-The Redis PHP extension repository is located at
-`https://github.com/nicolasff/phpredis <https://github.com/nicolasff/phpredis>`_.
+For more information on Redis, please see
+`http://redis.io <http://redis.io>`_.

Subject: [PATCH 2552/5397] Enable HTTP Verb in Routing

Using array for HTTP Verb

e.g:
$route['(:any)']['POST'] = "controller/post_method";
$route['path']['GET'] = "controller/path_get_method";
$route['path']['(:any)'] = "controller/path_any_method";

Using (:any) or not will make same result
e.g: $route['path']['(:any)'] == $route['path']

So it won't break existing route

+Using HTTP Verb in Routes
+=========================
+
+If you prefer you can use HTTP Verb (or method) to define your routing rules.
+This is particularly useful when building RESTful application. You can use standard HTTP
+Verb (GET, PUT, POST, DELETE) or custom HTTP Verb (e.g: PURGE). HTTP Verb rule is case 
+insensitive. All you need to do is add array index using HTTP Verb rule. Example::
+
+	$route['products']['put'] = 'product/insert';
+
+In the above example, a PUT request to URI "products" would call the "product" controller
+class and "insert" method
+
+::
+
+	$route['products/(:num)']['DELETE'] = 'product/delete/$1';
+
+A DELETE request to URL with "products" as first segment and a number in the second will be
+remapped to the "product" class and "delete" method passing in the match as a variable to
+the method.
+
+::
+
+	$route['products/([a-z]+)/(\d+)']['get'] = 'product/$1/$2';
+
+A GET request to a URI similar to products/shirts/123 would call the "product" controller
+class and "shirt" method with number as method parameter
+
+Using HTTP Verb is optional, so if you want any HTTP Verb to be handled in one rule
+You could just write your routing rule without HTTP Verb. Example::
+
+	$route['product'] = 'product';
+
+This way, all incoming request using any HTTP method containing the word "product"
+in the first segment will be remapped to "product" class
+

-Using HTTP Verb in Routes
-=========================
+Using HTTP verbs in routes
+==========================
 
-If you prefer you can use HTTP Verb (or method) to define your routing rules.
-This is particularly useful when building RESTful application. You can use standard HTTP
-Verb (GET, PUT, POST, DELETE) or custom HTTP Verb (e.g: PURGE). HTTP Verb rule is case 
-insensitive. All you need to do is add array index using HTTP Verb rule. Example::
+It is possible to use HTTP verbs (request method) to define your routing rules.
+This is particularly useful when building RESTful applications. You can use standard HTTP
+verbs (GET, PUT, POST, DELETE, PATCH) or a custom one such (e.g. PURGE). HTTP verb rules
+are case-insensitive. All you need to do is to add the verb as an array key to your route.
+Example::
 
 	$route['products']['put'] = 'product/insert';
 
-In the above example, a PUT request to URI "products" would call the "product" controller
-class and "insert" method
+In the above example, a PUT request to URI "products" would call the ``Product::insert()``
+controller method.
 
 ::
 
 	$route['products/(:num)']['DELETE'] = 'product/delete/$1';
 
-A DELETE request to URL with "products" as first segment and a number in the second will be
-remapped to the "product" class and "delete" method passing in the match as a variable to
-the method.
-
-::
-
-	$route['products/([a-z]+)/(\d+)']['get'] = 'product/$1/$2';
-
-A GET request to a URI similar to products/shirts/123 would call the "product" controller
-class and "shirt" method with number as method parameter
-
-Using HTTP Verb is optional, so if you want any HTTP Verb to be handled in one rule
-You could just write your routing rule without HTTP Verb. Example::
-
-	$route['product'] = 'product';
+A DELETE request to URL with "products" as first the segment and a number in the second will be
+mapped to the ``Product::delete()`` method, passing the numeric value as the first parameter.
 
-This way, all incoming request using any HTTP method containing the word "product"
-in the first segment will be remapped to "product" class
+Using HTTP verbs is of course, optional.

-Step 8: Move your error templates directory
-*******************************************
+************************************
+Step 8: Replace your error templates
+************************************
 
-In version 3.0.0, the errors folder has been moved from _application/errors* to _application/views/errors*.
+In CodeIgniter 3.0, the error templates are now considered as views and have been moved to the
+_application/views/errors* directory.
+
+Furthermore, we've added support for CLI error templates in plain-text format that unlike HTML,
+is suitable for the command line. This of course requires another level of separation.
+
+It is safe to move your old templates from _application/errors* to _application/views/errors/html*,
+but you'll have to copy the new _application/views/errors/cli* directory from the CodeIgniter archive.

Subject: [PATCH 2587/5397] Remove _serialize() and _unserialize() methods

Since removing the unneeded manual escaping code, there is no-longer any reason
to have the serialization functions abstracted. This also allows us to only
suppress errors when unserializing cookie data, and only trim when we are
unserializing database data (see commit 6b8312).

-$this->output->get_header()
-===========================
+		.. important:: Make sure any non-mime string you pass to this method
+			exists in *application/config/mimes.php* or it will have no effect.
 
-Gets the requested HTTP header value, if set.
+		You can also set the character set of the document, by passing a second argument::
 
-If the header is not set, NULL will be returned.
-If an empty value is passed to the method, it will return FALSE.

-Example::
+	.. method:: get_content_type()
 
-	$this->output->set_content_type('text/plain', 'UTF-8');
-	echo $this->output->get_header('content-type');
-	// Outputs: text/plain; charset=utf-8
+		:returns: string
 
-.. note:: The header name is compared in a case-insensitive manner.
+		Returns the Content-Type HTTP header that's currently in use, excluding the character set value.

-$this->output->get_output()
-===========================
+		.. note:: If not set, the default return value is 'text/html'.
 
-Permits you to manually retrieve any output that has been sent for
-storage in the output class. Usage example::
+	.. method:: get_header($header)
 
-	$string = $this->output->get_output();
+		:param string $header: HTTP header name
+		:returns: string
 
-Note that data will only be retrievable from this function if it has
-been previously sent to the output class by one of the CodeIgniter
-functions like $this->load->view().
+		Returns the requested HTTP header value, or NULL if the requested header is not set.
+		Example::
 
-$this->output->append_output();
-================================
+			$this->output->set_content_type('text/plain', 'UTF-8');
+			echo $this->output->get_header('content-type');
+			// Outputs: text/plain; charset=utf-8
 
-Appends data onto the output string. Usage example::
+		.. note:: The header name is compared in a case-insensitive manner.
 
-	$this->output->append_output($data);
+		.. note:: Raw headers sent via PHP's native ``header()`` function are also detected.
 
-$this->output->set_header();
-=============================
+	.. method:: get_output()
 
-Permits you to manually set server headers, which the output class will
-send for you when outputting the final rendered display. Example::
+		:returns: string
 
-	$this->output->set_header("HTTP/1.0 200 OK");
-	$this->output->set_header("HTTP/1.1 200 OK");
-	$this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');

-	$this->output->set_header("Pragma: no-cache");
+		Permits you to manually retrieve any output that has been sent for
+		storage in the output class. Usage example::
 
-$this->output->set_status_header(code, 'text');
-=================================================
+			$string = $this->output->get_output();
 
-Permits you to manually set a server status header. Example::
+		Note that data will only be retrievable from this function if it has
+		been previously sent to the output class by one of the CodeIgniter
+		functions like ``$this->load->view()``.
 
-	$this->output->set_status_header('401');
-	// Sets the header as:  Unauthorized
+	.. method:: append_output($output)
 
-`See here <http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html>`_ for
-a full list of headers.

-Permits you to enable/disable the
-:doc:`Profiler <../general/profiling>`, which will display benchmark
-and other data at the bottom of your pages for debugging and
-optimization purposes.
+	.. method:: set_header($header[, $replace = TRUE])
 
-To enable the profiler place the following function anywhere within your
-:doc:`Controller <../general/controllers>` functions::
+		:param string $header: HTTP Header
+		:param bool $replace: Whether to replace the old header value, if it is already set
+		:returns: object
 
-	$this->output->enable_profiler(TRUE);
+		Permits you to manually set server headers, which the output class will
+		send for you when outputting the final rendered display. Example::
 
-When enabled a report will be generated and inserted at the bottom of
-your pages.
+			$this->output->set_header('HTTP/1.0 200 OK');

+The URI Class provides methods that help you retrieve information from
 your URI strings. If you use URI routing, you can also retrieve
 information about the re-routed segments.
 
 .. note:: This class is initialized automatically by the system so there
 	is no need to do it manually.
 
-$this->uri->segment(n)
-======================
+***************
+Class Reference
+***************
 
-Permits you to retrieve a specific segment. Where n is the segment
-number you wish to retrieve. Segments are numbered from left to right.
-For example, if your full URL is this::
+.. class:: CI_URI
 
-	http://example.com/index.php/news/local/metro/crime_is_up
+	.. method:: segment($n[, $no_result = NULL])
 
-The segment numbers would be this:
+		:param int $n: Segment index number
+		:param mixed $no_result: What to return if the searched segment is not found
+		:returns: mixed
 
-#. news
-#. local
-#. metro
-#. crime_is_up
+		Permits you to retrieve a specific segment. Where n is the segment
+		number you wish to retrieve. Segments are numbered from left to right.
+		For example, if your full URL is this::
 
-By default the function returns NULL if the segment does not
-exist. There is an optional second parameter that permits you to set
-your own default value if the segment is missing. For example, this
-would tell the function to return the number zero in the event of
-failure::
+			http://example.com/index.php/news/local/metro/crime_is_up
 
-	$product_id = $this->uri->segment(3, 0);
+		The segment numbers would be this:
 
-It helps avoid having to write code like this::
+		#. news
+		#. local
+		#. metro
+		#. crime_is_up
 
-	if ($this->uri->segment(3) === FALSE)
-	{
-	    $product_id = 0;
-	}
-	else
-	{
-	    $product_id = $this->uri->segment(3);
-	}
+		The optional second parameter defaults to NULL and allows you to set the return value
+		of this method when the requested URI segment is missing.
+		For example, this would tell the method to return the number zero in the event of failure::
 
-$this->uri->rsegment(n)
-=======================
+			$product_id = $this->uri->segment(3, 0);
 
-This function is identical to the previous one, except that it lets you
-retrieve a specific segment from your re-routed URI in the event you are
-using CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
+		It helps avoid having to write code like this::
 
-$this->uri->slash_segment(n)
-=============================
+			if ($this->uri->segment(3) === FALSE)
+			{
+				$product_id = 0;
+			}
+			else
+			{
+				$product_id = $this->uri->segment(3);
+			}
 
-This function is almost identical to $this->uri->segment(), except it
-adds a trailing and/or leading slash based on the second parameter. If

+		Returns:
 
-	index.php/user/search/name/joe/location/UK/gender/male
+		#. segment/
+		#. /segment
+		#. /segment/
 
-Using this function you can turn the URI into an associative array with
-this prototype::
+	.. method:: slash_rsegment($n[, $where = 'trailing'])
 
-	[array]
-	(
-	    'name' => 'joe'

-	)
+		:param int $n: Segment index number
+		:param string $where: Where to add the slash ('trailing' or 'leading')
+		:returns: string
 
-The first parameter of the function lets you set an offset. By default
-it is set to 3 since your URI will normally contain a
-controller/function in the first and second segments. Example::
+		This method is identical to ``slash_segment()``, except that it lets you

+		:returns: array
 
-The second parameter lets you set default key names, so that the array
-returned by the function will always contain expected indexes, even if
-missing from the URI. Example::

-Lastly, if a corresponding value is not found for a given key (if there
-is an odd number of URI segments) the value will be set to FALSE
-(boolean).
+		The first parameter lets you set an offset, which defaults to 3 since your

-This function is identical to the previous one, except that it creates
-an associative array using the re-routed URI in the event you are using
-CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
+		The second parameter lets you set default key names, so that the array
+		returned will always contain expected indexes, even if missing from the URI.
+		Example::
 
-$this->uri->assoc_to_uri()
-============================
+			$default = array('name', 'gender', 'location', 'type', 'sort');
+			$array = $this->uri->uri_to_assoc(3, $default);
 
-Takes an associative array as input and generates a URI string from it.
-The array keys will be included in the string. Example::
+		If the URI does not contain a value in your default, an array index will
+		be set to that name, with a value of NULL.
 
-	$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');
+		Lastly, if a corresponding value is not found for a given key (if there
+		is an odd number of URI segments) the value will be set to NULL.
 
-	$str = $this->uri->assoc_to_uri($array);
+	.. method:: ruri_to_assoc([$n = 3[, $default = array()]])
 
-	// Produces: product/shoes/size/large/color/red
+		:param int $n: Segment index number
+		:param array $default: Default values
+		:returns: array
 
-$this->uri->uri_string()
-=========================
+		This method is identical to ``uri_to_assoc()``, except that it creates
+		an associative array using the re-routed URI in the event you are using
+		CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
 
-Returns a string with the complete URI. For example, if this is your
-full URL::
+	.. method:: assoc_to_uri($array)
 
-	http://example.com/index.php/news/local/345
+		:param array $array: Input array of key/value pairs
+		:returns: string
 
-The function would return this::
+		Takes an associative array as input and generates a URI string from it.

-
-****************
-Helper Reference
-****************
-
-The following helper functions are available for use in the view files
-containing your forms. Note that these are procedural functions, so they
-**do not** require you to prepend them with $this->form_validation.
-
-form_error()
-============
-
-Shows an individual error message associated with the field name
-supplied to the function. Example::
+	.. method:: error_string([$prefix = ''[, $suffix = '']])
 
-	<?php echo form_error('username'); ?>
-
-The error delimiters can be optionally specified. See the
-:ref:`changing-delimiters` section above.
-
-validation_errors()
-===================
-
-Shows all error messages as a string: Example::
-
-	<?php echo validation_errors(); ?>
-
-The error delimiters can be optionally specified. See the
-:ref:`changing-delimiters` section above.
-
-set_value()
-===========
+		:param string $prefix: Error message prefix
+		:param string $suffix: Error message suffix
+		:returns: string
 
-Permits you to set the value of an input form or textarea. You must
-supply the field name via the first parameter of the function. The
-second (optional) parameter allows you to set a default value for the
-form. Example::
+		Returns all error messages (as returned from error_array()) formatted as a
+		string and separated by a newline character.
 
-	<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />
+	.. method:: error($field[, $prefix = ''[, $suffix = '']])
 
-The above form will show "0" when loaded for the first time.
+		:param string $field: Field name
+		:param string $prefix: Optional prefix
+		:param string $suffix: Optional suffix
+		:returns: string
 
-set_select()
-============
+		Returns the error message for a specific field, optionally adding a
+		prefix and/or suffix to it (usually HTML tags).
 
-If you use a <select> menu, this function permits you to display the
-menu item that was selected. The first parameter must contain the name
-of the select menu, the second parameter must contain the value of each
-item, and the third (optional) parameter lets you set an item as the
-default (use boolean TRUE/FALSE).
+	.. method:: has_rule($field)
 
-Example::
+		:param string $field: Field name
+		:returns: bool
 
-	<select name="myselect">
-	<option value="one" <?php echo set_select('myselect', 'one', TRUE); ?> >One</option>
-	<option value="two" <?php echo set_select('myselect', 'two'); ?> >Two</option>
-	<option value="three" <?php echo set_select('myselect', 'three'); ?> >Three</option>
-	</select>
+		Checks to see if there is a rule set for the specified field.
 
-set_checkbox()
-==============
-
-Permits you to display a checkbox in the state it was submitted. The
-first parameter must contain the name of the checkbox, the second
-parameter must contain its value, and the third (optional) parameter
-lets you set an item as the default (use boolean TRUE/FALSE). Example::
-
-	<input type="checkbox" name="mycheck[]" value="1" <?php echo set_checkbox('mycheck[]', '1'); ?> />
-	<input type="checkbox" name="mycheck[]" value="2" <?php echo set_checkbox('mycheck[]', '2'); ?> />
+.. _helper-functions:
 
-set_radio()
-===========
+****************
+Helper Reference
+****************
 
-Permits you to display radio buttons in the state they were submitted.
-This function is identical to the **set_checkbox()** function above.
+Please refer to the :doc:`Form Helper <../helpers/form_helper>` manual for
+the following functions:
 
-::
+-  :func:`form_error()`
+-  :func:`validation_errors()`
+-  :func:`set_value()`
+-  :func:`set_select()`
+-  :func:`set_checkbox()`
+-  :func:`set_radio()`
 
-	<input type="radio" name="myradio" value="1" <?php echo set_radio('myradio', '1', TRUE); ?> />
-	<input type="radio" name="myradio" value="2" <?php echo set_radio('myradio', '2'); ?> />
+Note that these are procedural functions, so they **do not** require you
+to prepend them with ``$this->form_validation``.

+======================
 
-For example, if you would like to send email with CodeIgniter, the first
-step is to load the email class within your controller::
+An application package allows for the easy distribution of complete sets
+of resources in a single directory, complete with its own libraries,
+models, helpers, config, and language files. It is recommended that
+these packages be placed in the application/third_party directory. Below
+is a sample map of an package directory.
 
-	$this->load->library('email');
+The following is an example of a directory for an application package
+named "Foo Bar".
 
-Once loaded, the library will be ready for use, using
-$this->email->*some_method*().

-Library files can be stored in subdirectories within the main

+	/application/third_party/foo_bar
 
-	libraries/flavors/Chocolate.php
+	config/

+	language/
+	libraries/
+	models/
 
-You will load it using::
+Whatever the purpose of the "Foo Bar" application package, it has its
+own config files, helpers, language files, libraries, and models. To use
+these resources in your controllers, you first need to tell the Loader
+that you are going to be loading resources from a package, by adding the
+package path via the ``add_package_path()`` method.
 
-	$this->load->library('flavors/chocolate');
+Package view files
+------------------
 
-You may nest the file in as many subdirectories as you want.
+By Default, package view files paths are set when ``add_package_path()``
+is called. View paths are looped through, and once a match is
+encountered that view is loaded.
 
-Additionally, multiple libraries can be loaded at the same time by
-passing an array of libraries to the load method.
+In this instance, it is possible for view naming collisions within
+packages to occur, and possibly the incorrect package being loaded. To
+ensure against this, set an optional second parameter of FALSE when
+calling ``add_package_path()``.

+				'priority' => '1'

-Setting options

-The second (optional) parameter allows you to optionally pass
-configuration settings. You will typically pass these as an array::
+		Config options can usually also be set via a config file. Each library
+		is explained in detail in its own page, so please read the information
+		regarding each one you would like to use.
 
-	$config = array(
-		'sess_driver' => 'cookie',
-		'sess_encrypt_cookie'  => true,
-		'encryption_key' => 'mysecretkey'
-	);
+		Please take note, when multiple libraries are supplied in an array for

-$this->load->view('file_name', $data, TRUE/FALSE)
-=================================================
+		This method is used to load driver libraries, acts very much like the
+		``library()`` method.
 
-This method is used to load your View files. If you haven't read the
-:doc:`Views <../general/views>` section of the user guide it is
-recommended that you do since it shows you how this method is
-typically used.
+		As an example, if you would like to use sessions with CodeIgniter, the first
+		step is to load the session driver within your controller::
 
-The first parameter is required. It is the name of the view file you
-would like to load.
+			$this->load->driver('session');
 
-.. note:: The .php file extension does not need to be specified unless
-	you use something other than .php.
+		Once loaded, the library will be ready for use, using ``$this->session``.
 
-The second **optional** parameter can take an associative array or an
-object as input, which it runs through the PHP
-`extract() <http://www.php.net/extract>`_ function to convert to variables
-that can be used in your view files. Again, read the
-:doc:`Views <../general/views>` page to learn how this might be useful.
+		Driver files must be stored in a subdirectory within the main
+		"libraries" directory, or within your personal *application/libraries*

-The third **optional** parameter lets you change the behavior of the
-method so that it returns data as a string rather than sending it to
-your browser. This can be useful if you want to process the data in some
-way. If you set the parameter to true (boolean) it will return data. The
-default behavior is false, which sends it to your browser. Remember to
-assign it to a variable if you want the data returned::
+		Additionally, multiple driver libraries can be loaded at the same time by
+		passing an array of drivers to the load method.
+		::
 
-	$string = $this->load->view('myfile', '', true);
+			$this->load->driver(array('session', 'cache'));
 
-$this->load->model('model_name');
-==================================
+		Setting options
+		---------------
 
-::
+		The second (optional) parameter allows you to optionally pass
+		configuration settings. You will typically pass these as an array::
 
-	$this->load->model('model_name');
+			$config = array(
+				'sess_driver' => 'cookie',
+				'sess_encrypt_cookie'  => true,
+				'encryption_key' => 'mysecretkey'
+			);
 
+			$this->load->driver('session', $config);
 
-If your model is located in a subdirectory, include the relative path
-from your models directory. For example, if you have a model located at
-application/models/blog/queries.php you'll load it using::
+		Config options can usually also be set via a config file. Each library
+		is explained in detail in its own page, so please read the information
+		regarding each one you would like to use.
 
-	$this->load->model('blog/queries');
+		Assigning a Driver to a different object name
+		---------------------------------------------
 
-If you would like your model assigned to a different object name you can
-specify it via the second parameter of the loading method::
+		If the third (optional) parameter is blank, the library will be assigned
+		to an object with the same name as the parent class. For example, if
+		the library is named Session, it will be assigned to a variable named
+		``$this->session``.
 
-	$this->load->model('model_name', 'fubar');
-	$this->fubar->method();
+		If you prefer to set your own class names you can pass its value to the
+		third parameter::
 
-$this->load->database('options', TRUE/FALSE)
-============================================
+			$this->load->library('session', '', 'my_session');
 
-This method lets you load the database class. The two parameters are
-**optional**. Please see the :doc:`database <../database/index>`
-section for more info.

-This method takes an associative array as input and generates
-variables using the PHP `extract <http://www.php.net/extract>`_
-method. This method produces the same result as using the second
-parameter of the ``$this->load->view()`` method above. The reason you
-might want to use this method independently is if you would like to

-$this->load->get_var($key)
-==========================
+		This method is used to load your View files. If you haven't read the
+		:doc:`Views <../general/views>` section of the user guide it is
+		recommended that you do since it shows you how this method is
+		typically used.
 
-This method checks the associative array of variables available to
-your views. This is useful if for any reason a var is set in a library
-or another controller method using ``$this->load->vars()``.
+		The first parameter is required. It is the name of the view file you
+		would like to load.
 
-$this->load->get_vars()
-=======================
+		.. note:: The .php file extension does not need to be specified unless
+			you use something other than .php.
 
-This method retrieves all variables available to your views.
+		The second **optional** parameter can take an associative array or an
+		object as input, which it runs through the PHP
+		`extract() <http://www.php.net/extract>`_ function to convert to variables
+		that can be used in your view files. Again, read the
+		:doc:`Views <../general/views>` page to learn how this might be useful.

-================================
+		The third **optional** parameter lets you change the behavior of the

+		default behavior is FALSE, which sends it to your browser. Remember to
+		assign it to a variable if you want the data returned::
 
-This method loads helper files, where file_name is the name of the
-file, without the _helper.php extension.
+			$string = $this->load->view('myfile', '', TRUE);
 
-$this->load->file('filepath/filename', TRUE/FALSE)
-==================================================
+	.. method:: vars($vars[, $val = ''])
 
-This is a generic file loading method. Supply the filepath and name in
-the first parameter and it will open and read the file. By default the
-data is sent to your browser, just like a View file, but if you set the
-second parameter to true (boolean) it will instead return the data as a
-string.
+		:param mixed $vars: An array of variables or a single variable name
+		:param mixed $val: Optional variable value

-Application "Packages"
-======================
+	.. method:: get_vars()
 
-An application package allows for the easy distribution of complete sets
-of resources in a single directory, complete with its own libraries,
-models, helpers, config, and language files. It is recommended that
-these packages be placed in the application/third_party directory. Below
-is a sample map of an package directory
+		:returns: array
 
-Sample Package "Foo Bar" Directory Map
-======================================
+		This method retrieves all variables available to your views.
 
-The following is an example of a directory for an application package
-named "Foo Bar".
+	.. method:: model($model[, $name = ''[, $db_conn = FALSE]])
 
-::
+		:param mixed $model: Model name or an array containing multiple models
+		:param string $name: Optional object name to assign the model to
+		:param string $db_conn: Optional database configuration group to load
+		:returns: void

+		::
 
-	config/
-	helpers/
-	language/
-	libraries/
-	models/
+			$this->load->model('model_name');
 
-Whatever the purpose of the "Foo Bar" application package, it has its
-own config files, helpers, language files, libraries, and models. To use
-these resources in your controllers, you first need to tell the Loader
-that you are going to be loading resources from a package, by adding the
-package path.
 
-$this->load->add_package_path()
----------------------------------
+		If your model is located in a subdirectory, include the relative path
+		from your models directory. For example, if you have a model located at
+		*application/models/blog/queries.php* you'll load it using::
 
-Adding a package path instructs the Loader class to prepend a given path
-for subsequent requests for resources. As an example, the "Foo Bar"
-application package above has a library named Foo_bar.php. In our
-controller, we'd do the following::
+			$this->load->model('blog/queries');
 
-	$this->load->add_package_path(APPPATH.'third_party/foo_bar/');
-	$this->load->library('foo_bar');
+		If you would like your model assigned to a different object name you can
+		specify it via the second parameter of the loading method::
 
-$this->load->remove_package_path()
-------------------------------------
+			$this->load->model('model_name', 'fubar');
+			$this->fubar->method();
 
-When your controller is finished using resources from an application
-package, and particularly if you have other application packages you
-want to work with, you may wish to remove the package path so the Loader
-no longer looks in that directory for resources. To remove the last path
-added, simply call the method with no parameters.
+	.. method:: database([$params = ''[, $return = FALSE[, $query_builder = NULL]]])
 
-$this->load->remove_package_path()
-------------------------------------
+		:param mixed $params: Database group name or configuration options
+		:param bool $return: Whether to return the loaded database object
+		:param bool $query_builder: Whether to load the Query Builder
+		:returns: mixed
 
-Or to remove a specific package path, specify the same path previously
-given to add_package_path() for a package.::
+		This method lets you load the database class. The two parameters are
+		**optional**. Please see the :doc:`database <../database/index>`
+		section for more info.
 
-	$this->load->remove_package_path(APPPATH.'third_party/foo_bar/');
+	.. method:: dbforge([$db = NULL[, $return = FALSE]])
 
-Package view files
-------------------
+		:param object $db: Database object
+		:param bool $return: Whether to return the Database Forge instance
+		:returns: mixed
 
-By Default, package view files paths are set when add_package_path()
-is called. View paths are looped through, and once a match is
-encountered that view is loaded.
+		Loads the :doc:`Database Forge <../database/forge>` class, please refer
+		to that manual for more info.
 
-In this instance, it is possible for view naming collisions within
-packages to occur, and possibly the incorrect package being loaded. To
-ensure against this, set an optional second parameter of FALSE when
-calling add_package_path().
+	.. method:: dbutil([$db = NULL[, $return = FALSE]])
 
-::
+		:param object $db: Database object
+		:param bool $return: Whether to return the Database Utilities instance
+		:returns: mixed

 ===========
 
@@ -162,134 +163,10 @@ Setting preferences in a config file
 If you prefer not to set preferences using the above method, you can
 instead put them into a config file. Simply create a new file called
 image_lib.php, add the $config array in that file. Then save the file
-in: config/image_lib.php and it will be used automatically. You will
-NOT need to use the $this->image_lib->initialize function if you save
+in *config/image_lib.php* and it will be used automatically. You will
+NOT need to use the ``$this->image_lib->initialize()``method if you save
 your preferences in a config file.
 
-$this->image_lib->resize()
-===========================
-
-The image resizing function lets you resize the original image, create a
-copy (with or without resizing), or create a thumbnail image.
-
-For practical purposes there is no difference between creating a copy
-and creating a thumbnail except a thumb will have the thumbnail marker
-as part of the name (ie, mypic_thumb.jpg).
-
-All preferences listed in the table above are available for this
-function except these three: rotation_angle, x_axis, and y_axis.
-
-Creating a Thumbnail
---------------------
-
-The resizing function will create a thumbnail file (and preserve the
-original) if you set this preference to TRUE::
-
-	$config['create_thumb'] = TRUE;
-
-This single preference determines whether a thumbnail is created or not.
-
-Creating a Copy
----------------
-
-The resizing function will create a copy of the image file (and preserve
-the original) if you set a path and/or a new filename using this
-preference::
-
-	$config['new_image'] = '/path/to/new_image.jpg';
-
-Notes regarding this preference:
-
--  If only the new image name is specified it will be placed in the same
-   folder as the original
--  If only the path is specified, the new image will be placed in the
-   destination with the same name as the original.
--  If both the path and image name are specified it will placed in its
-   own destination and given the new name.
-
-Resizing the Original Image
----------------------------
-
-If neither of the two preferences listed above (create_thumb, and
-new_image) are used, the resizing function will instead target the
-original image for processing.
-
-$this->image_lib->crop()
-=========================
-
-The cropping function works nearly identically to the resizing function
-except it requires that you set preferences for the X and Y axis (in
-pixels) specifying where to crop, like this::
-
-	$config['x_axis'] = '100';
-	$config['y_axis'] = '40';
-
-All preferences listed in the table above are available for this
-function except these: rotation_angle, create_thumb, new_image.
-
-Here's an example showing how you might crop an image::
-
-	$config['image_library'] = 'imagemagick';
-	$config['library_path'] = '/usr/X11R6/bin/';
-	$config['source_image']	= '/path/to/image/mypic.jpg';
-	$config['x_axis'] = '100';
-	$config['y_axis'] = '60';
-
-	$this->image_lib->initialize($config); 
-
-	if ( ! $this->image_lib->crop())
-	{
-	    echo $this->image_lib->display_errors();
-	}
-
-.. note:: Without a visual interface it is difficult to crop images, so this
-	function is not very useful unless you intend to build such an
-	interface. That's exactly what we did using for the photo gallery module
-	in ExpressionEngine, the CMS we develop. We added a JavaScript UI that
-	lets the cropping area be selected.
-
-$this->image_lib->rotate()
-===========================
-
-The image rotation function requires that the angle of rotation be set
-via its preference::
-
-	$config['rotation_angle'] = '90';
-
-There are 5 rotation options:
-
-#. 90 - rotates counter-clockwise by 90 degrees.
-#. 180 - rotates counter-clockwise by 180 degrees.
-#. 270 - rotates counter-clockwise by 270 degrees.
-#. hor - flips the image horizontally.
-#. vrt - flips the image vertically.
-
-Here's an example showing how you might rotate an image::
-
-	$config['image_library'] = 'netpbm';
-	$config['library_path'] = '/usr/bin/';
-	$config['source_image']	= '/path/to/image/mypic.jpg';
-	$config['rotation_angle'] = 'hor';
-
-	$this->image_lib->initialize($config); 
-
-	if ( ! $this->image_lib->rotate())
-	{
-	    echo $this->image_lib->display_errors();
-	}
-
-$this->image_lib->clear()
-==========================
-
-The clear function resets all of the values used when processing an
-image. You will want to call this if you are processing images in a
-loop.
-
-::
-

+Class Reference
+***************
+
+.. class:: CI_Image_lib
+
+	.. method:: initialize([$props = array()])
+
+		:param array $props: Image processing preferences
+		:returns: void
+
+		Initializes the class for processing an image.
+
+	.. method:: resize()
+
+		:returns: bool
+
+		The image resizing method lets you resize the original image, create a
+		copy (with or without resizing), or create a thumbnail image.
+
+		For practical purposes there is no difference between creating a copy
+		and creating a thumbnail except a thumb will have the thumbnail marker
+		as part of the name (i.e. mypic_thumb.jpg).
+
+		All preferences listed in the :ref:`processing-preferences` table are available for this
+		method except these three: *rotation_angle*, *x_axis* and *y_axis*.
+
+		Creating a Thumbnail
+		--------------------
+
+		The resizing method will create a thumbnail file (and preserve the
+		original) if you set this preference to TRUE::
+
+			$config['create_thumb'] = TRUE;
+
+		This single preference determines whether a thumbnail is created or not.
+
+		Creating a Copy
+		---------------
+
+		The resizing method will create a copy of the image file (and preserve
+		the original) if you set a path and/or a new filename using this
+		preference::
+
+			$config['new_image'] = '/path/to/new_image.jpg';
+
+		Notes regarding this preference:
+
+		-  If only the new image name is specified it will be placed in the same
+		   folder as the original
+		-  If only the path is specified, the new image will be placed in the
+		   destination with the same name as the original.
+		-  If both the path and image name are specified it will placed in its
+		   own destination and given the new name.
+
+		Resizing the Original Image
+		---------------------------
+
+		If neither of the two preferences listed above (create_thumb, and
+		new_image) are used, the resizing method will instead target the
+		original image for processing.
+
+	.. method:: crop()
+
+		:returns: bool
+
+		The cropping method works nearly identically to the resizing function
+		except it requires that you set preferences for the X and Y axis (in
+		pixels) specifying where to crop, like this::
+
+			$config['x_axis'] = '100';
+			$config['y_axis'] = '40';
+
+		All preferences listed in the :ref:`processing-preferences` table are available for this
+		method except these: *rotation_angle*, *create_thumb* and *new_image*.
+
+		Here's an example showing how you might crop an image::
+
+			$config['image_library'] = 'imagemagick';
+			$config['library_path'] = '/usr/X11R6/bin/';
+			$config['source_image']	= '/path/to/image/mypic.jpg';
+			$config['x_axis'] = '100';
+			$config['y_axis'] = '60';
+
+			$this->image_lib->initialize($config); 
+
+			if ( ! $this->image_lib->crop())
+			{
+				echo $this->image_lib->display_errors();
+			}
+
+		.. note:: Without a visual interface it is difficult to crop images, so this
+			method is not very useful unless you intend to build such an
+			interface. That's exactly what we did using for the photo gallery module
+			in ExpressionEngine, the CMS we develop. We added a JavaScript UI that
+			lets the cropping area be selected.
+
+	.. method:: rotate()
+
+		:returns: bool
+
+		The image rotation method requires that the angle of rotation be set
+		via its preference::
+
+			$config['rotation_angle'] = '90';
+
+		There are 5 rotation options:
+
+		#. 90 - rotates counter-clockwise by 90 degrees.
+		#. 180 - rotates counter-clockwise by 180 degrees.
+		#. 270 - rotates counter-clockwise by 270 degrees.
+		#. hor - flips the image horizontally.
+		#. vrt - flips the image vertically.
+
+		Here's an example showing how you might rotate an image::
+
+			$config['image_library'] = 'netpbm';
+			$config['library_path'] = '/usr/bin/';
+			$config['source_image']	= '/path/to/image/mypic.jpg';
+			$config['rotation_angle'] = 'hor';
+
+			$this->image_lib->initialize($config); 
+
+			if ( ! $this->image_lib->rotate())
+			{
+				echo $this->image_lib->display_errors();
+			}
+
+	.. method:: watermark()
+
+		:returns: bool
+
+		Creates a watermark over an image, please refer to the :ref:`watermarking`
+		section for more info.		
+
+	.. method:: clear()
+
+		:returns: void
+
+		The clear method resets all of the values used when processing an
+		image. You will want to call this if you are processing images in a
+		loop.
+
+		::
+
+			$this->image_lib->clear();
+
+	.. method:: display_errors([$open = '<p>[, $close = '</p>']])
+
+		:param string $open: Error message opening tag
+		:param string $close: Error message closing tag
+		:returns: string

Subject: [PATCH 2630/5397] Fix #2143

When trying to load rules from a configuration file, the Form validation library matched against
ruri_string() as opposed to 'controller/method' like described in the manual. Since ruri_string()
also makes sense, now both are being checked with ruri_string() having a higher precedence.

Supersedes PR #2224

Subject: [PATCH 2646/5397] Fix #148

CI_Input::_clean_input_data() assumed that all input data is URL-encoded while sanitizing it.
However, PHP already performs URL-decoding on it, so this is either redudant or overly
intrusive as it resulted in many, many reports of data containing '%' followed by 1 numeric
characters being essentially destroyed.

Supersedes PR #1229

Subject: [PATCH 2648/5397] Fix #346

When ['global_xss_filtering'] was turned on, the , ,  &
superglobals were automatically overwritten. This resulted in one of the following problems:

 - xss_clean() being called twice
 - Inability to retrieve the original (not filtered) value

XSS filtering is now only applied on demand by the Input class, and the default value for
the  parameter in CI_Input methods is changed to NULL. Unless a boolean value is
passed to them, whether XSS filtering is applied depends on the ['global_xss_filtering']
value.

+Step 11: Usage of XSS filtering
+*******************************
+
+Many functions in CodeIgniter allow you to use its XSS filtering feature

+parameter used to be boolean FALSE, but it is now changed to NULL and it
+will be dynamically determined by your ``$config['global_xss_filtering']``
+value.

+If you used to manually pass a boolean value for the ``$xss_filter``
+parameter or if you've always had ``$config['global_xss_filtering']`` set

+
+ - :doc:`Cookie Helper <../helpers/cookie_helper>` :func:`get_cookie()`
+

 :doc:`Smiley Helper <../helpers/smiley_helper>` function ``js_insert_smiley()`` has been deprecated

+Database drivers 'mysql', 'sqlite', 'mssql', 'pdo/dblib'
+========================================================
+
+The **mysql** driver utilizes the old 'mysql' PHP extension, known for its aging code base and
+many low-level problems. The extension is deprecated as of PHP 5.5 and CodeIgniter deprecates
+it in version 3.0, switching the default configured MySQL driver to **mysqli**.
+
+Please use either the 'mysqli' or 'pdo/mysql' drivers for MySQL. The old 'mysql' driver will be
+removed at some point in the future.
+
+The **sqlite**, **mssql** and **pdo/dblib** (also known as pdo/mssql or pdo/sybase) drivers
+all depend on PHP extensions that for different reasons no longer exist since PHP 5.3.
+
+Therefore we are now deprecating these drivers as we will have to remove them in one of the next
+CodeIgniter versions. You should use the more advanced, **sqlite3**, **sqlsrv** or **pdo/sqlsrv**
+drivers respectively.
+
+.. note:: These drivers are still available, but you're strongly encouraged to switch to other ones
+	sooner rather than later.

Subject: [PATCH 2658/5397] Remove preg_quote() call from
 CI_User_agent::_set_browser() and add another pattern for Opera

Input comes from a configuration file that is barely touched by anyone
and the default values only contain letters, so it is safe to not
quote them.

This enables us to add a more advanced pattern in config/user_agents.php
for Opera 10+, which ... quote:

  Opera/9.80 is hard coded at the beginning of the user agent string because of broken browser sniffing scripts which detect 'Opera/10' and above as Opera 1.

(reference: http://my.opera.com/community/openweb/idopera/)

Instead, latests versions of Opera append ' Version/<version number>'
to the end of the user agent string.

Fixes issue #555 (incorrect browser detection for Opera)

 -  Fixed a bug (#346) - with ``$config['global_xss_filtering']`` turned on, the ``$_GET``, ``$_POST``, ``$_COOKIE`` and ``$_SERVER`` superglobals were overwritten during initialization time, resulting in XSS filtering being either performed twice or there was no possible way to get the original data, even though options for this do exist.

Subject: [PATCH 2694/5397] Don't throw in mock autoloader

This behavior doesn't appear to be used at all.

This fixes HHVM compatibility: HHVM optimizes class_exists() to a
dedicated bytecode - as it's not a function call, it doesn't show up
in the backtrace. 100% of the tests pass with this change.

Subject: [PATCH 2698/5397] Fix incorrect checks for the fwrite() return value

! fwrite() could trigger false-positives as it is possible for it to return 0
instead of boolean FALSE. (issue #2822)

Also removed an unnecessary log level check that caused an extra space to be inserted
for the INFO level. (proposed in PR #2821)

Subject: [PATCH 2699/5397] CI_URI changes related to the 'permitted_uri_chars'
 setting

 - Initialize and cache the value in the class constructor instead of searching for it every time
 - Removed the preg_quote() call from _filter_uri() to allow more fine-tuning from configuration
 - Renamed _filter_uri() to filter_uri() - it was public anyway and using it cannot break anything

Related: issue #2799

Subject: [PATCH 2701/5397] Fix #2822: Incorrect usage of fwrite()

We only used to check (and not always) if the return value of fwrite() is boolean FALSE,
while it is possible that the otherwise returned bytecount is less than the length of
data that we're trying to write. This allowed incomplete writes over network streams
and possibly a few other edge cases.

    -  :doc:`URI Library <libraries/uri>` changes include:
 
-      -  Renamed method ``_filter_uri()`` to ``filter_uri()`` and removed the ``preg_quote()`` call from it.
+      -  Added conditional PCRE UTF-8 support to the "invalid URI characters" check and removed the ``preg_quote()`` call from it to allow more flexibility.
+      -  Renamed method ``_filter_uri()`` to ``filter_uri()``.
       -  Changed private methods to protected so that MY_URI can override them.
       -  Renamed internal method ``_parse_cli_args()`` to ``_parse_argv()``.
       -  Renamed internal method ``_detect_uri()`` to ``_parse_request_uri()``.

Subject: [PATCH 2703/5397] URI Routing overhaul

 - Allow multiple levels of controller directories (supersedes PRs #390, #2439)
 - Add support for per-directory 'defaul_controller' and '404_override' (resolves issue #2611; supersedes PR #939)
 - Fixed a bug where default_controller was called instead of triggering 404 if the current route is inside a directory
 - Removed a few calls from CI_Router to CI_URI that made a necessity for otherwise internal CI_URI methods to be public:

    - Removed CI_URI::_fetch_uri_string() and moved its logic into CI_URI::__construct()
    - Removed CI_URI::_remove_url_suffix, CI_URI::_explode_segments() and moved their logic into CI_URI::_set_uri_string()
    - Removed CI_URI::_reindex_segments() altogether ( doesn't need further manipulation, while  is
      public anyway and can be properly (and more effectively) replaced on the spot)

Subject: [PATCH 2709/5397] Minor changes related to CI_User_agent

Fixed a bug where both accept_charset() and accept_lang() improperly parsed headers
if they contained spaces between data separators (which is valid).

Also made is_referral() testable by replacing its static cache var with a class
property and added some more unit tests for the library as a whole.

Subject: [PATCH 2765/5397] More CI_Encryption improvements

 - Make OpenSSL the default driver if available (because MCrypt is stupid).
 - Require MCRYPT_DEV_URANDOM for the MCrypt availability check
   (because security; also, incidentally - it's faster that way ;)).

Subject: [PATCH 2789/5397] simplify calendar library

it seemed quite strange that we ask users to pass in a template string the we parse with REGEX, to extract key/value pairs, when we can simply ask users for an array.

the class still contains default variables for each part of the template. Users can simply pass in an array (instead of a string) when they initialize, $config['template'], which overwrites default values.

this cuts down a little on file size by removing parse_template() function.
I think arrays are much more straightforward and easy to read than 'encoded' strings.
don't have to keep a running list of all template keys like in previous parse_template() function.
gets rid of $this->temp[] property and changes it to $this->template[] which is more descriptive when generating output

Subject: [PATCH 2791/5397] CI_Input tweaks

 - Make get_post(), post_get() and server()'s  parameter mandatory.
 - Change default value of  parameter to NULL for cookie(), input_stream() and _fetch_from_array()
   (for consistency with get(), post()).
 - Delegate Array-vs-single and  parameter detection to _fetch_from_array() to overall simplify the code.

 default!
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I think its better to enable this basic security options by default.
It’s more likely that users who build a new website or application from
ground up, and use CodeIgniter can get used to this and eventually turn
this off. From a web security perspective, we can support a more secure
web, by default! Who agrees?

Use of || is discouraged as its clarity on some output devices is low
(looking like the number 11 for instance). && is preferred over AND but
either are acceptable, and a space should always precede and follow !

+##################
+Encryption Library
+##################
+
+The Encryption Library provides two-way data encryption. To do so in
+a cryptographically secure way, it utilizes PHP extensions that are
+unfortunately not always available on all systems.
+You must meet one of the following dependancies in order to use this
+library:
+
+- `OpenSSL <http://php.net/openssl>`_ (and PHP 5.3.3)
+- `MCrypt <http://php.net/mcrypt>`_ (and `MCRYPT_DEV_URANDOM` availability)
+
+If neither of the above dependancies is met, we simply cannot offer
+you a good enough implementation to meet the high standards required
+for proper cryptography.
+
+.. contents::
+  :local:
+
+.. raw:: html
+
+  <div class="custom-index container"></div>
+
+****************************
+Using the Encryption Library
+****************************
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Encryption library is
+initialized in your controller using the ``$this->load->library()``
+method::
+
+	$this->load->library('encrypt');
+
+Once loaded, the Encryption library object will be available using::
+
+	$this->encrypt
+
+Default behavior
+================
+
+By default, the Encryption Library will use the AES-128 cipher in CBC
+mode, using your configured *encryption_key* and SHA512 HMAC authentication.
+
+.. note:: AES-128 is chosen both because it is proven to be strong and
+	because of its wide availability across different cryptographic
+	software and programming languages' APIs.
+
+However, the *encryption_key* is not used as is.
+
+If you are somewhat familiar with cryptography, you should already know
+that a HMAC also requires a secret key and using the same key for both
+encryption and authentication is a bad practice.
+
+Because of that, two separate keys are derived from your already configured
+*encryption_key*: one for encryption and one for authentication. This is
+done via a technique called `HMAC-based Key Derivation Function
+<http://en.wikipedia.org/wiki/HKDF>`_ (HKDF).
+
+Setting your encryption_key
+===========================
+
+An *encryption key* is a piece of information that controls the
+cryptographic process and permits a plain-text string to be encrypted,
+and afterwards - decrypted. It is the secret "ingredient" in the whole
+process that allows you to be the only one who is able to decrypt data
+that you've decided to hide from the eyes of the public.
+After one key is used to encrypt data, that same key provides the **only**
+means to decrypt it, so not only must you chose one carefully, but you
+must not lose it or you will also use the encrypted data.
+
+It must be noted that to ensure maximum security, such key *should* not
+only be as strong as possible, but also often changed. Such behavior
+however is rarely practical or possible to implement, and that is why
+CodeIgniter gives you the ability to configure a single key that is to be
+used (almost) every time.
+
+It goes without saying that you should guard your key carefully. Should
+someone gain access to your key, the data will be easily decrypted. If
+your server is not totally under your control it's impossible to ensure
+key security so you may want to think carefully before using it for
+anything that requires high security, like storing credit card numbers.
+
+Your encryption key should be as long as the encyption algorithm in use
+allows. For AES-128, that's 128 bits or 16 bytes (charcters) long. The
+key should be as random as possible and it should **not** be a simple
+text string.
+
+You will find a table below that shows the supported key lengths of
+different ciphers.
+
+The key can be either stored in your *application/config/config.php*, or
+you can design your own storage mechanism and pass the key dynamically
+when encrypting/decrypting.
+
+To save your key to your *application/config/config.php*, open the file
+and set::
+
+	$config['encryption_key'] = 'YOUR KEY';
+
+.. _ciphers-and-modes:
+
+Supported encryption ciphers and modes
+======================================
+
+.. note:: The terms 'cipher' and 'encryption algorithm' are interchangeable.
+
+Portable ciphers
+----------------
+
+Because MCrypt and OpenSSL (also called drivers throughout this document)
+each support different sets of encryption algorithms and often implement
+them in different ways, our Encryption library is designed to use them in
+a portable fashion, or in other words - it enables you to use them
+interchangeably, at least for the ciphers supported by both drivers.
+
+It is also implemented in a way that aims to match the standard
+implementations in other programming languages and libraries.
+
+Here's a list of the so called "portable" ciphers, where
+"CodeIgniter name" is the string value that you'd have to pass to the
+Encryption library to use that cipher:
+
+======================== ================== ============================ ===============================
+Cipher name              CodeIgniter name   Key lengths (bits / bytes)   Supported modes
+======================== ================== ============================ ===============================
+AES-128 / Rijndael-128   aes-128            128 / 16                     CBC, CTR, CFB, CFB8, OFB, ECB
+AES-192                  aes-192            192 / 24                     CBC, CTR, CFB, CFB8, OFB, ECB
+AES-256                  aes-256            256 / 32                     CBC, CTR, CFB, CFB8, OFB, ECB
+DES                      des                56 / 7                       CBC, CFB, CFB8, OFB, ECB
+TripleDES                tripledes          56 / 7, 112 / 14, 168 / 21   CBC, CFB, CFB8, OFB
+Blowfish                 blowfish           128-448 / 16-56              CBC, CFB, OFB, ECB
+CAST5 / CAST-128         cast5              40-128 / 5-16                CBC, CFB, OFB, ECB
+RC4 / ARCFour            rc4                40-2048 / 5-256              Stream
+======================== ================== ============================ ===============================
+
+.. important:: Because of how MCrypt works, if you fail to provide a key
+	with the appropriate length, you might end up using a different
+	algorithm than the one configured, so be really careful with that!
+
+.. note:: In case it isn't clear from the above table, Blowfish, CAST5
+	and RC4 support variable length keys. That is, any number in the
+	shown ranges is valid, although in bit terms that only happens
+	in 8-bit increments.
+
+.. note:: Even though CAST5 supports key lengths lower than 128 bits
+	(16 bytes), in fact they will just be zero-padded to the
+	maximum length, as specified in `RFC 2144
+	<http://tools.ietf.org/rfc/rfc2144.txt>`_.
+
+.. note:: Blowfish supports key lengths as small as 32 bits (4 bytes), but
+	our tests have shown that only lengths of 128 bits (16 bytes) or
+	higher are properly supported by both MCrypt and OpenSSL. It is
+	also a bad practice to use such low-length keys anyway.
+
+Driver-specific ciphers
+-----------------------
+
+As noted above, MCrypt and OpenSSL support different sets of encryption
+ciphers. For portability reasons and because we haven't tested them
+properly, we do not advise you to use the ones that are driver-specific,
+but regardless, here's a list of most of them:
+
+

+============== ========= ============================== =========================================
+
+.. note:: If you wish to use one of those ciphers, you'd have to pass
+	its name in lower-case to the Encryption library.
+
+.. note:: You've probably noticed that all AES cipers (and Rijndael-128)
+	are also listed in the portable ciphers list. This is because
+	drivers support different modes for these ciphers. Also, it is
+	important to note that AES-128 and Rijndael-128 are actually
+	the same cipher, but **only** when used with a 128-bit key.
+
+.. note:: RC2 is listed as supported by both MCrypt and OpenSSL.
+	However, both drivers implement them differently and they
+	are not portable. It is probably worth noting that we only
+	found one obscure source confirming that it is MCrypt that
+	is not properly implementing it.
+
+.. _encryption-modes:
+
+Encryption modes
+----------------
+
+Different modes of encryption have different characteristics and serve
+for different purposes. Some are stronger than others, some are faster
+and some offer extra features.
+We are not going in depth into that here, we'll leave that to the
+cryptography experts. The table below is to provide brief informational
+reference to our more experienced users. If you are a beginner, just
+stick to the CBC mode - it is widely accepted as strong and secure for
+general purposes.
+
+=========== ================== ================= ===================================================================================================================================================
+Mode name   CodeIgniter name   Driver support    Additional info
+=========== ================== ================= ===================================================================================================================================================
+CBC         cbc                MCrypt, OpenSSL   A safe default choice
+CTR         ctr                MCrypt, OpenSSL   Considered as theoretically better than CBC, but not as widely available
+CFB         cfb                MCrypt, OpenSSL   N/A
+CFB8        cfb8               MCrypt, OpenSSL   Same as CFB, but operates in 8-bit mode (not recommended).
+OFB         ofb                MCrypt, OpenSSL   N/A
+OFB8        ofb8               MCrypt            Same as OFB, but operates in 8-bit mode (not recommended).
+ECB         ecb                MCrypt, OpenSSL   Ignores IV (not recommended).
+GCM         gcm                OpenSSL           Provides authentication and therefore doesn't need a HMAC.
+XTS         xts                OpenSSL           Usually used for encrypting random access data such as RAM or hard-disk storage.
+Stream      stream             MCrypt, OpenSSL   This is not actually a mode, it just says that a stream cipher is being used. Required because of the general cipher+mode initialization process.
+=========== ================== ================= ===================================================================================================================================================
+
+Message Length
+==============
+
+It's probably important for you to know that an encrypted string is usually
+longer than the original, plain-text string (depending on the cipher).
+
+This is influenced by the cipher algorithm itself, the IV prepended to the
+cipher-text and (unless you are using GCM mode) the HMAC authentication
+message that is also prepended. Furthermore, the encrypted message is also
+Base64-encoded so that it is safe for storage and transmission, regardless
+of a possible character set in use.
+
+Keep this information in mind when selecting your data storage mechanism.
+Cookies, for example, can only hold 4K of information.
+
+.. _configuration:
+
+Configuring the library
+=======================
+
+For usability, performance, but also historical reasons tied to our old
+:doc:`Encrypt Class <encrypt>`, the Encryption library is designed to
+use repeatedly the same driver, encryption cipher, mode and key.
+
+As noted in the "Default behavior" section above, this means using an
+auto-detected driver (OpenSSL has a higher priority), the AES-128 ciper
+in CBC mode, and your ``$config['encryption_key']`` value.
+
+If you wish to change that however, you need to use the ``initialize()``
+method. It accepts an associative array of parameters, all of which are
+optional:
+
+======== ===============================================
+Option   Possible values
+======== ===============================================
+driver   'mcrypt', 'openssl'
+cipher   Cipher name (see :ref:`ciphers-and-modes`)
+mode     Encryption mode (see :ref:`encryption-modes`)
+key      Encryption key 
+======== ===============================================
+
+For example, if you were to change the encryption algorithm and
+mode to AES-256 in CTR mode, this is what you should do::
+
+	$this->encryption->initialize(
+		array(
+			'cipher' => 'aes-256',
+			'mode' => 'ctr',
+			'key' => '<a 32-character random string>'
+		)
+	);
+
+Note that we only mentioned that you want to change the ciper and mode,
+but we also included a key in the example. As previously noted, it is
+important that you choose a key with a proper size for the used algorithm.
+
+There's also the ability to change the driver, if for some reason you
+have both, but want to use MCrypt instead of OpenSSL::
+
+	// Switch to the MCrypt driver
+	$this->encryption->initialize(array('driver' => 'mcrypt'));
+
+	// Switch back to the OpenSSL driver
+	$this->encryption->initialize(array('driver' => 'openssl'));
+
+Encrypting and decrypting data
+==============================
+
+Encrypting and decrypting data with the already configured library
+settings is simple. As simple as just passing the string to the
+``encrypt()`` and/or ``decrypt()`` methods::
+
+	$plain_text = 'This is a plain-text message!';
+	$ciphertext = $this->encryption->encrypt($plain_text);
+
+	// Outputs: This is a plain-text message!
+	echo $this->encryption->decrypt($ciphertext);
+
+And that's it! The Encryption library will do everything necessary
+for the whole process to be cryptographically secure out-of-the-box.
+You don't need to worry about it.
+
+.. important:: Both methods will return FALSE in case of an error.
+	While for ``encrypt()`` this can only mean incorrect
+	configuration, you should always check the return value
+	of ``decrypt()`` in production code.
+
+How it works
+------------
+
+If you must know how the process works, here's what happens under
+the hood:
+
+- ``$this->encryption->encrypt($plain_text)``
+
+  #. Derive an encryption key and a HMAC key from your configured
+     *encryption_key* via HKDF, using the SHA-512 digest algorithm.
+
+  #. Generate a random initialization vector (IV).
+
+  #. Encrypt the data via AES-128 in CBC mode (or another previously
+     configured cipher and mode), using the above-mentioned derived
+     encryption key and IV.
+
+  #. Prepend said IV to the resulting cipher-text.
+
+  #. Base64-encode the resulting string, so that it can be safely
+     stored or transferred without worrying about character sets.
+
+  #. Create a SHA-512 HMAC authentication message using the derived
+     HMAC key to ensure data integrity and prepend it to the Base64
+     string.
+
+- ``$this->encryption->decrypt($ciphertext)``
+
+  #. Derive an encryption key and a HMAC key from your configured
+     *encryption_key* via HKDF, using the SHA-512 digest algorithm.
+     Because your configured *encryption_key* is the same, this
+     will produce the same result as in the ``encrypt()`` method
+     above - otherwise you won't be able to decrypt it.
+
+  #. Check if the string is long enough, separate the HMAC out of
+     it and validate if it is correct (this is done in a way that
+     prevents timing attacks agains it). Return FALSE if either of
+     the checks fails.
+
+  #. Base64-decode the string.
+
+  #. Separate the IV out of the cipher-text and decrypt the said
+     cipher-text using that IV and the derived encryption key.
+
+.. _custom-parameters:
+
+Using custom parameters
+-----------------------
+
+Let's say you have to interact with another system that is out
+of your control and uses another method to encrypt data. A
+method that will most certainly not match the above-described
+sequence and probably not use all of the steps either.
+
+The Encryption library allows you to change how its encryption
+and decryption processes work, so that you can easily tailor a
+custom solution for such situations.
+
+.. note:: It is possible to use the library in this way, without
+	setting an *encryption_key* in your configuration file.
+
+All you have to do is to pass an associative array with a few
+parameters to either the ``encrypt()`` or ``decrypt()`` method.
+Here's an example::
+
+	// Assume that we have $ciphertext, $key and $hmac_key
+	// from on outside source
+
+	$message = $this->encryption->decrypt(
+		$ciphertext,
+		array(
+			'cipher' => 'blowfish',
+			'mode' => 'cbc',
+			'key' => $key,
+			'hmac_digest' => 'sha256',
+			'hmac_key' => $hmac_key
+		)
+	);
+
+In the above example, we are decrypting a message that was encrypted
+using the Blowfish cipher in CBC mode and authenticated via a SHA-256
+HMAC.
+
+.. important:: Note that both 'key' and 'hmac_key' are used in this
+	example. When using custom parameters, encryption and HMAC keys
+	are not derived like the default behavior of the library is.
+
+Below is a list of the available options.
+
+However, unless you really need to and you know what you are doing,
+we advise you to not change the encryption process as this could
+impact security, so please do so with caution.
+
+============= =============== ============================= ======================================================
+Option        Default value   Mandatory / Optional          Description
+============= =============== ============================= ======================================================
+cipher        N/A             Yes                           Encryption algorithm (see :ref:`ciphers-and-modes`).
+mode          N/A             Yes                           Encryption mode (see :ref:`encryption-modes`).
+key           N/A             Yes                           Encryption key.
+iv            N/A             No                            Initialization vector (IV).
+                                                            If not provided it will be automatically generated
+                                                            during encryption and looked for during decryption.
+hmac          TRUE            No                            Whether to use a HMAC.
+                                                            Boolean. If set to FALSE, then *hmac_digest* and
+                                                            *hmac_key* will be ignored.
+hmac_digest   sha512          No                            HMAC message digest algorithm (see :ref:`digests`).
+hmac_key      N/A             Yes, unless *hmac* is FALSE   HMAC key.
+raw_data      FALSE           No                            Whether the cipher-text should be raw.
+                                                            Boolean. If set to TRUE, then Base64 encoding and
+                                                            decoding will not be performed and HMAC will not
+                                                            be a hexadecimal string.
+============= =============== ============================= ======================================================
+
+.. important:: ``encrypt()`` and ``decrypt()`` will return FALSE if
+	a mandatory parameter is not provided or if a provided
+	value is incorrect. This includes *hmac_key*, unless *hmac*
+	is set to FALSE.
+
+.. note:: If GCM mode is used, *hmac* will always be FALSE. This is
+	because GCM mode itself provides authentication.
+
+.. _digests:
+
+Supported HMAC authentication algorithms
+----------------------------------------
+
+For HMAC message authentication, the Encryption library supports
+usage of the SHA-2 family of algorithms:
+
+=========== ==================== ============================
+Algorithm   Raw length (bytes)   Hex-encoded length (bytes)
+=========== ==================== ============================
+sha512      64                   128
+sha384      48                   96
+sha256      32                   64
+sha224      28                   56
+=========== ==================== ============================
+
+The reason for not including other popular algorithms, such as
+MD5 or SHA1 is that they are no longer considered secure enough
+and as such, we don't want to encourage their usage.
+If you absolutely need to use them, it is easy to do so via PHP's
+native `hash_hmac() <http://php.net/hash_hmac()>`_ function.
+
+Stronger algorithms of course will be added in the future as they
+appear and become widely available.

Subject: [PATCH 2836/5397] Introducing compatibility layers

 - Limited support for mbstring (mb_strlen(), mb_strpos(), mb_substr() only) via iconv.
   Falls back to regular strlen(), strpos(), substr() if iconv is not available.
 - Password hashing, dependant on CRYPT_BLOWFISH (2y version, available since PHP 5.3.7) availability.

+#######################
+Compatibility Functions
+#######################
+
+CodeIgniter provides a set of compatibility functions that enable
+you to use functions what are otherwise natively available in PHP,
+but only in higher versions or depending on a certain extension.
+
+Being custom implementations, these functions will also have some
+set of dependancies on their own, but are still useful if your
+PHP setup doesn't offer them natively.
+
+.. note:: Much like the `common functions <common_functions>`, the
+	compatibility functions are always available, as long as
+	their dependancies are met.
+
+.. contents::
+  :local:
+
+.. raw:: html
+
+  <div class="custom-index container"></div>
+
+****************
+Password Hashing
+****************
+
+This set of compatibility functions offers a "backport" of PHP's
+standard `Password Hashing extension <http://php.net/password>`_
+that is otherwise available only since PHP 5.5.
+
+Dependancies
+============
+
+- PHP 5.3.7
+- ``CRYPT_BLOWFISH`` support for ``crypt()``
+
+Constants
+=========
+
+- ``PASSWORD_BCRYPT``
+- ``PASSWORD_DEFAULT``
+
+Function reference
+==================
+
+.. function:: password_get_info($hash)
+
+	:param	string	$hash: Password hash
+	:returns:	Information about the hashed password
+	:rtype:	array
+
+	For more information, please refer to the `PHP manual for
+	password_get_info() <http://php.net/password_get_info>`_.
+
+.. function:: password_hash($password, $algo[, $options = array()])
+
+	:param	string	$password: Plain-text password
+	:param	int	$algo: Hashing algorithm
+	:param	array	$options: Hashing options
+	:returns:	Hashed password or FALSE on failure
+	:rtype:	string
+
+	For more information, please refer to the `PHP manual for
+	password_hash() <http://php.net/password_hash>`_.
+
+	.. note:: Unless you provide your own (and valid) salt, this function
+		has a further dependancy on an available CSPRNG source. Each
+		of the following would satisfy that:
+		- ``mcrypt_create_iv()`` with ``MCRYPT_DEV_URANDOM``
+		- ``openssl_random_pseudo_bytes()``
+		- /dev/arandom
+		- /dev/urandom
+
+.. function:: password_needs_rehash()
+
+	:param	string	$hash: Password hash
+	:param	int	$algo: Hashing algorithm
+	:param	array	$options: Hashing options
+	:returns:	TRUE if the hash should be rehashed to match the given algorithm and options, FALSE otherwise
+	:rtype:	bool
+
+	For more information, please refer to the `PHP manual for
+	password_needs_rehash() <http://php.net/password_needs_rehash>`_.
+
+.. function:: password_verify($password, $hash)
+
+	:param	string	$password: Plain-text password
+	:param	string	$hash: Password hash
+	:returns:	TRUE if the password matches the hash, FALSE if not
+	:rtype:	bool
+
+	For more information, please refer to the `PHP manual for
+	password_verify() <http://php.net/password_verify>`_.
+
+****************
+Multibyte String
+****************
+
+This set of compatibility functions offers limited support for PHP's
+`Multibyte String extension <http://php.net/mbstring>`_. Because of
+the limited alternative solutions, only a few functions are available.
+
+.. note:: When a character set parameter is ommited,
+	``$config['charset']`` will be used.
+
+Dependancies
+============
+
+- `iconv <http://php.net/iconv>`_ extension
+
+.. important:: This dependancy is optional and these functions will
+	always be declared. If iconv is not available, they WILL
+	fall-back to their non-mbstring versions.
+
+.. important:: Where a character set is supplied, it must be
+	supported by iconv and in a format that it recognizes.
+
+.. note:: For you own dependancy check on the actual mbstring
+	extension, use the ``MB_ENABLED`` constant.
+
+Function reference
+==================
+
+.. function:: mb_strlen($str[, $encoding = NULL])
+
+	:param	string	$str: Input string
+	:param	string	$encoding: Character set
+	:returns:	Number of characters in the input string or FALSE on failure
+	:rtype:	string
+
+	For more information, please refer to the `PHP manual for
+	mb_strlen() <http://php.net/mb_strlen>`_.
+
+.. function:: mb_strpos($haystack, $needle[, $offset = 0[, $encoding = NULL]])
+
+	:param	string	$haystack: String to search in
+	:param	string	$needle: Part of string to search for
+	:param	int	$offset: Search offset
+	:param	string	$encoding: Character set
+	:returns:	Numeric character position of where $needle was found or FALSE if not found
+	:rtype:	mixed
+
+	For more information, please refer to the `PHP manual for
+	mb_strpos() <http://php.net/mb_strpos>`_.
+
+.. function:: mb_substr($str, $start[, $length = NULL[, $encoding = NULL]])
+
+	:param	string	$str: Input string
+	:param	int	$start: Position of first character
+	:param	int	$length: Maximum number of characters
+	:param	string	$encoding: Character set
+	:returns:	Portion of $str specified by $start and $length or FALSE on failure
+	:rtype:	string
+
+	For more information, please refer to the `PHP manual for
+	mb_substr() <http://php.net/mb_substr>`_.

       -  ``UTF8_ENABLED`` now requires only one of `Multibyte String <http://php.net/mbstring>`_ or `iconv <http://php.net/iconv>`_ to be available instead of both.
       -  Changed method ``clean_string()`` to utilize ``mb_convert_encoding()`` if it is available but ``iconv()`` is not.
+      -  Renamed method ``_is_ascii()`` to ``is_ascii()`` and made it public.
 
    -  Added `compatibility layers <general/compatibility_functions>` for PHP's `mbstring <http://php.net/mbstring>`_ (limited support) and `password <http://php.net/password>`_ extensions.
    -  Removed ``CI_CORE`` boolean constant from *CodeIgniter.php* (no longer Reactor and Core versions).

This prevents a possible recursion when an error is trigerred by one of the config file.
Also since the variable is used only later in the code it makes sense to move it lower.

    -  Renamed internal method ``_escape_identifiers()`` to ``escape_identifiers()``.
    -  Updated ``escape_identifiers()`` to accept an array of fields as well as strings.
    -  MySQL and MySQLi drivers now require at least MySQL version 5.1.
+   -  Added a ``$persistent`` parameter to ``db_connect()`` and changed ``db_pconnect()`` to be an alias for ``db_connect(TRUE)``.
    -  ``db_set_charset()`` now only requires one parameter (collation was only needed due to legacy support for MySQL versions prior to 5.1).
-   -  ``db_select()`` will now always (if required by the driver) be called by ``db_connect()`` / ``db_pconnect()`` instead of only when initializing.
+   -  ``db_select()`` will now always (if required by the driver) be called by ``db_connect()`` instead of only when initializing.
    -  Replaced the ``_error_message()`` and ``_error_number()`` methods with ``error()``, which returns an array containing the last database error code and message.
    -  Improved ``version()`` implementation so that drivers that have a native function to get the version number don't have to be defined in the core ``DB_driver`` class.
    -  Added capability for packages to hold *config/database.php* config files.

+Callable: Use anything as a rule
+================================
+
+If callback rules aren't good enough for you (for example, because they are
+limited to your controller), don't get disappointed, there's one more way
+to create custom rules: anything that ``is_callable()`` would return TRUE for.
+
+Consider the following example::
+
+	$this->form_validation->set_rules(
+		'username', 'Username',
+		array(
+			'required',
+			array($this->users_model, 'valid_username')
+		)
+	);
+
+The above code would use the ``valid_username()`` method from your
+``Users_model`` object.
+
+This is just an example of course, and callbacks aren't limited to models.
+You can use any object/method that accepts the field value as its' first
+parameter. Or if you're running PHP 5.3+, you can also use an anonymous
+function:
+
+	$this->form_validation->set_rules(
+		'username', 'Username',
+		array(
+			'required',
+			function($value)
+			{
+				// Check $value and return TRUE/FALSE

This one is great because we don't have to deal with the special cases:
* in Windows, dirname('/foo/index.php') gives "/foo", but dirname('/index.php') gives "\" instead of "/"
* dirname() doesn't include the trailing slash, with the expection of "/" (root)

Subject: [PATCH 3000/5397] Add hash_equals() to ext/hash compat layer

Introduced in PHP 5.6 Beta 1 (unfortunately, still undocumented).
RFC: https://wiki.php.net/rfc/timing_attack

(Yes, I am aware that the RFC talks about hash_compare(), the function was later renamed in the implementation.)

  * CodeIgniter Session Class
  *
- * The user interface defined by EllisLabs, now with puggable drivers to manage different storage mechanisms.
- * By default, the cookie session driver will load, but the 'sess_driver' config/param item (see above) can be
- * used to specify the 'native' driver, or any other you might create.
- * Once loaded, this driver setup is a drop-in replacement for the former CI_Session library, taking its place as the
- * 'session' member of the global controller framework (e.g.: $CI->session or $this->session).
- * In keeping with the CI_Driver methodology, multiple drivers may be loaded, although this might be a bit confusing.
- * The CI_Session library class keeps track of the most recently loaded driver as "current" to call for driver methods.
- * Ideally, one driver is loaded and all calls go directly through the main library interface. However, any methods
- * called through the specific driver will switch the "current" driver to itself before invoking the library method
- * (which will then call back into the driver for low-level operations). So, alternation between two drivers can be
- * achieved by specifying which driver to use for each call (e.g.: $this->session->native->set_userdata('foo', 'bar');
- * $this->session->cookie->userdata('foo'); $this->session->native->unset_userdata('foo');). Notice in the previous
- * example that the _native_ userdata value 'foo' would be set to 'bar', which would NOT be returned by the call for
- * the _cookie_ userdata 'foo', nor would the _cookie_ value be unset by the call to unset the _native_ 'foo' value.

-/**
- * CI_Session_driver Class
- *
- * Extend this class to make a new CI_Session driver.
- * A CI_Session driver basically manages an array of name/value pairs with some sort of storage mechanism.
- * To make a new driver, derive from (extend) CI_Session_driver. Overload the initialize method and read or create
- * session data. Then implement a save handler to write changed data to storage (sess_save), a destroy handler
- * to remove deleted data (sess_destroy), and an access handler to expose the data (get_userdata).
- * Put your driver in the libraries/Session/drivers folder anywhere in the loader paths. This includes the
- * application directory, the system directory, or any path you add with $CI->load->add_package_path().
- * Your driver must be named CI_Session_<name>, and your filename must be Session_<name>.php,
- * preferably also capitalized. (e.g.: CI_Session_foo in libraries/Session/drivers/Session_foo.php)
- * Then specify the driver by setting 'sess_driver' in your config file or as a parameter when loading the CI_Session
- * object. (e.g.: $config['sess_driver'] = 'foo'; OR $CI->load->driver('session', array('sess_driver' => 'foo')); )
- * Already provided are the Native driver, which manages the native PHP $_SESSION array, and
- * the Cookie driver, which manages the data in a browser cookie, with optional extra storage in a database table.

 Encrypt Class
 #############
 
-The Encrypt Class provides two-way data encryption. It uses a scheme
-that either compiles the message using a randomly hashed bitwise XOR
-encoding scheme, or is encrypted using the Mcrypt library. If Mcrypt is
-not available on your server the encoded message will still provide a
-reasonable degree of security for encrypted sessions or other such
-"light" purposes. If Mcrypt is available, you'll be provided with a high
-degree of security appropriate for storage.
+The Encrypt Class provides two-way data encryption. It encrypted using
+the Mcrypt PHP extension, which is required for the Encrypt Class to run.
 
 .. important:: This library has been DEPRECATED and is only kept for
 	backwards compatibility. Please use the new :doc:`Encryption Library

 you can design your own storage mechanism and pass the key dynamically
 when encrypting/decrypting.

Subject: [PATCH 3064/5397] Remove GCM mode from CI_Encryption (OpenSSL)

While openssl_get_cipher_methods() lists 'aes-<keysize>-gcm' as supported,
it appears that this is only half of the story. To be more specific, only
the encryption operation of GCM is performed, and the authentication message
is completely missing, rendering the whole thing useles.

Subject: [PATCH 3067/5397] Return 403 instead of 500 if no CSRF token given

Not supplying a CSRF token shouldn't return a 500 response because it isn't a server error. The response status code should definitely be in the 400's, because it's the client's fault. And it should be a 403 because the client is forbidden from making that request without the appropriate credential (the CSRF token), though the request may be otherwise valid.

 With regular expressions, you can also catch a segment containing a
 forward slash ('/'), which would usually represent the delimiter between
 multiple segments.

 For example, if a user accesses a password protected area of your web
 application and you wish to be able to redirect them back to the same
 page after they log in, you may find this example useful::
 
 	$route['login/(.+)'] = 'auth/login/$1';

 For those of you who don't know regular expressions and want to learn
 more about them, `regular-expressions.info <http://www.regular-expressions.info/>`
 might be a good starting point.

-Open Software License ("OSL") v 3.0
-
-This Open Software License (the "License") applies to any original work of
-authorship (the "Original Work") whose owner (the "Licensor") has placed the
-following licensing notice adjacent to the copyright notice for the Original
-Work:
-
-Licensed under the Open Software License version 3.0
-
-1) Grant of Copyright License. Licensor grants You a worldwide, royalty-free,
-non-exclusive, sublicensable license, for the duration of the copyright, to do
-the following:
-
-	a) to reproduce the Original Work in copies, either alone or as part of a
-		collective work;
-
-	b) to translate, adapt, alter, transform, modify, or arrange the Original
-		Work, thereby creating derivative works ("Derivative Works") based
-		upon the Original Work;
-
-	c) to distribute or communicate copies of the Original Work and Derivative
-		Works to the public, with the proviso that copies of Original Work or
-		Derivative Works that You distribute or communicate shall be licensed
-		under this Open Software License;
-
-	d) to perform the Original Work publicly; and
-
-	e) to display the Original Work publicly.
-
-2) Grant of Patent License. Licensor grants You a worldwide, royalty-free,
-non-exclusive, sublicensable license, under patent claims owned or controlled
-by the Licensor that are embodied in the Original Work as furnished by the
-Licensor, for the duration of the patents, to make, use, sell, offer for sale,
-have made, and import the Original Work and Derivative Works.
-
-3) Grant of Source Code License. The term "Source Code" means the preferred
-form of the Original Work for making modifications to it and all available
-documentation describing how to modify the Original Work. Licensor agrees to
-provide a machine-readable copy of the Source Code of the Original Work along
-with each copy of the Original Work that Licensor distributes. Licensor
-reserves the right to satisfy this obligation by placing a machine-readable
-copy of the Source Code in an information repository reasonably calculated to
-permit inexpensive and convenient access by You for as long as Licensor
-continues to distribute the Original Work.
-
-4) Exclusions From License Grant. Neither the names of Licensor, nor the names
-of any contributors to the Original Work, nor any of their trademarks or
-service marks, may be used to endorse or promote products derived from this
-Original Work without express prior permission of the Licensor. Except as
-expressly stated herein, nothing in this License grants any license to
-Licensor's trademarks, copyrights, patents, trade secrets or any other
-intellectual property. No patent license is granted to make, use, sell, offer
-for sale, have made, or import embodiments of any patent claims other than the
-licensed claims defined in Section 2. No license is granted to the trademarks
-of Licensor even if such marks are included in the Original Work. Nothing in
-this License shall be interpreted to prohibit Licensor from licensing under
-terms different from this License any Original Work that Licensor otherwise
-would have a right to license.
-
-5) External Deployment. The term "External Deployment" means the use,
-distribution, or communication of the Original Work or Derivative Works in any
-way such that the Original Work or Derivative Works may be used by anyone
-other than You, whether those works are distributed or communicated to those
-persons or made available as an application intended for use over a network.
-As an express condition for the grants of license hereunder, You must treat
-any External Deployment by You of the Original Work or a Derivative Work as a
-distribution under section 1(c).
-
-6) Attribution Rights. You must retain, in the Source Code of any Derivative
-Works that You create, all copyright, patent, or trademark notices from the
-Source Code of the Original Work, as well as any notices of licensing and any
-descriptive text identified therein as an "Attribution Notice." You must cause
-the Source Code for any Derivative Works that You create to carry a prominent
-Attribution Notice reasonably calculated to inform recipients that You have
-modified the Original Work.
-
-7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that
-the copyright in and to the Original Work and the patent rights granted herein
-by Licensor are owned by the Licensor or are sublicensed to You under the
-terms of this License with the permission of the contributor(s) of those
-copyrights and patent rights. Except as expressly stated in the immediately
-preceding sentence, the Original Work is provided under this License on an "AS
-IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without
-limitation, the warranties of non-infringement, merchantability or fitness for
-a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK
-IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this
-License. No license to the Original Work is granted by this License except
-under this disclaimer.
-
-8) Limitation of Liability. Under no circumstances and under no legal theory,
-whether in tort (including negligence), contract, or otherwise, shall the
-Licensor be liable to anyone for any indirect, special, incidental, or
-consequential damages of any character arising as a result of this License or
-the use of the Original Work including, without limitation, damages for loss
-of goodwill, work stoppage, computer failure or malfunction, or any and all
-other commercial damages or losses. This limitation of liability shall not
-apply to the extent applicable law prohibits such limitation.
-
-9) Acceptance and Termination. If, at any time, You expressly assented to this
-License, that assent indicates your clear and irrevocable acceptance of this
-License and all of its terms and conditions. If You distribute or communicate
-copies of the Original Work or a Derivative Work, You must make a reasonable
-effort under the circumstances to obtain the express assent of recipients to
-the terms of this License. This License conditions your rights to undertake
-the activities listed in Section 1, including your right to create Derivative
-Works based upon the Original Work, and doing so without honoring these terms
-and conditions is prohibited by copyright law and international treaty.
-Nothing in this License is intended to affect copyright exceptions and
-limitations (including "fair use" or "fair dealing"). This License shall
-terminate immediately and You may no longer exercise any of the rights granted
-to You by this License upon your failure to honor the conditions in Section
-1(c).
-
-10) Termination for Patent Action. This License shall terminate automatically
-and You may no longer exercise any of the rights granted to You by this
-License as of the date You commence an action, including a cross-claim or
-counterclaim, against Licensor or any licensee alleging that the Original Work
-infringes a patent. This termination provision shall not apply for an action
-alleging patent infringement by combinations of the Original Work with other
-software or hardware.
-
-11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this
-License may be brought only in the courts of a jurisdiction wherein the
-Licensor resides or in which Licensor conducts its primary business, and under
-the laws of that jurisdiction excluding its conflict-of-law provisions. The
-application of the United Nations Convention on Contracts for the
-International Sale of Goods is expressly excluded. Any use of the Original
-Work outside the scope of this License or after its termination shall be
-subject to the requirements and penalties of copyright or patent law in the
-appropriate jurisdiction. This section shall survive the termination of this
-License.
-
-12) Attorneys' Fees. In any action to enforce the terms of this License or
-seeking damages relating thereto, the prevailing party shall be entitled to
-recover its costs and expenses, including, without limitation, reasonable
-attorneys' fees and costs incurred in connection with such action, including
-any appeal of such action. This section shall survive the termination of this
-License.
-
-13) Miscellaneous. If any provision of this License is held to be
-unenforceable, such provision shall be reformed only to the extent necessary
-to make it enforceable.
-
-14) Definition of "You" in This License. "You" throughout this License,
-whether in upper or lower case, means an individual or a legal entity
-exercising rights under, and complying with all of the terms of, this License.
-For legal entities, "You" includes any entity that controls, is controlled by,
-or is under common control with you. For purposes of this definition,
-"control" means (i) the power, direct or indirect, to cause the direction or
-management of such entity, whether by contract or otherwise, or (ii) ownership
-of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial
-ownership of such entity.
-
-15) Right to Use. You may use the Original Work in all ways not otherwise
-restricted or conditioned by this License or by law, and Licensor promises not
-to interfere with or be responsible for such uses by You.
-
-16) Modification of This License. This License is Copyright © 2005 Lawrence
-Rosen. Permission is granted to copy, distribute, or communicate this License
-without modification. Nothing in this License permits You to modify this
-License as applied to the Original Work or to Derivative Works. However, You
-may modify the text of this License and copy, distribute or communicate your
-modified version (the "Modified License") and apply it to other original works
-of authorship subject to the following conditions: (i) You may not indicate in
-any way that your Modified License is the "Open Software License" or "OSL" and
-you may not use those names in the name of your Modified License; (ii) You
-must replace the notice specified in the first paragraph above with the notice
-"Licensed under <insert your license name here>" or with a notice of your own
-that is not confusingly similar to the notice in this License; and (iii) You
-may not claim that your original works are open source software unless your
-Modified License has been approved by Open Source Initiative (OSI) and You
-comply with its license review and certification process.

-modified the Original Work.
-
-7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that
-the copyright in and to the Original Work and the patent rights granted herein
-by Licensor are owned by the Licensor or are sublicensed to You under the
-terms of this License with the permission of the contributor(s) of those
-copyrights and patent rights. Except as expressly stated in the immediately
-preceding sentence, the Original Work is provided under this License on an "AS
-IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without
-limitation, the warranties of non-infringement, merchantability or fitness for
-a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK
-IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this
-License. No license to the Original Work is granted by this License except
-under this disclaimer.
-
-8) Limitation of Liability. Under no circumstances and under no legal theory,
-whether in tort (including negligence), contract, or otherwise, shall the
-Licensor be liable to anyone for any indirect, special, incidental, or
-consequential damages of any character arising as a result of this License or
-the use of the Original Work including, without limitation, damages for loss
-of goodwill, work stoppage, computer failure or malfunction, or any and all
-other commercial damages or losses. This limitation of liability shall not
-apply to the extent applicable law prohibits such limitation.
-
-9) Acceptance and Termination. If, at any time, You expressly assented to this
-License, that assent indicates your clear and irrevocable acceptance of this
-License and all of its terms and conditions. If You distribute or communicate
-copies of the Original Work or a Derivative Work, You must make a reasonable
-effort under the circumstances to obtain the express assent of recipients to
-the terms of this License. This License conditions your rights to undertake
-the activities listed in Section 1, including your right to create Derivative
-Works based upon the Original Work, and doing so without honoring these terms
-and conditions is prohibited by copyright law and international treaty.
-Nothing in this License is intended to affect copyright exceptions and
-limitations (including "fair use" or "fair dealing"). This License shall
-terminate immediately and You may no longer exercise any of the rights granted
-to You by this License upon your failure to honor the conditions in Section
-1(c).
-
-10) Termination for Patent Action. This License shall terminate automatically
-and You may no longer exercise any of the rights granted to You by this
-License as of the date You commence an action, including a cross-claim or
-counterclaim, against Licensor or any licensee alleging that the Original Work
-infringes a patent. This termination provision shall not apply for an action
-alleging patent infringement by combinations of the Original Work with other
-software or hardware.
-
-11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this
-License may be brought only in the courts of a jurisdiction wherein the
-Licensor resides or in which Licensor conducts its primary business, and under
-the laws of that jurisdiction excluding its conflict-of-law provisions. The
-application of the United Nations Convention on Contracts for the
-International Sale of Goods is expressly excluded. Any use of the Original
-Work outside the scope of this License or after its termination shall be
-subject to the requirements and penalties of copyright or patent law in the
-appropriate jurisdiction. This section shall survive the termination of this
-License.
-
-12) Attorneys' Fees. In any action to enforce the terms of this License or
-seeking damages relating thereto, the prevailing party shall be entitled to
-recover its costs and expenses, including, without limitation, reasonable
-attorneys' fees and costs incurred in connection with such action, including
-any appeal of such action. This section shall survive the termination of this
-License.
-
-13) Miscellaneous. If any provision of this License is held to be
-unenforceable, such provision shall be reformed only to the extent necessary
-to make it enforceable.
-
-14) Definition of "You" in This License. "You" throughout this License,
-whether in upper or lower case, means an individual or a legal entity
-exercising rights under, and complying with all of the terms of, this License.
-For legal entities, "You" includes any entity that controls, is controlled by,
-or is under common control with you. For purposes of this definition,
-"control" means (i) the power, direct or indirect, to cause the direction or
-management of such entity, whether by contract or otherwise, or (ii) ownership
-of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial
-ownership of such entity.
-
-15) Right to Use. You may use the Original Work in all ways not otherwise
-restricted or conditioned by this License or by law, and Licensor promises not
-to interfere with or be responsible for such uses by You.
-
-16) Modification of This License. This License is Copyright © 2005 Lawrence
-Rosen. Permission is granted to copy, distribute, or communicate this License
-without modification. Nothing in this License permits You to modify this
-License as applied to the Original Work or to Derivative Works. However, You
-may modify the text of this License and copy, distribute or communicate your
-modified version (the "Modified License") and apply it to other original works
-of authorship subject to the following conditions: (i) You may not indicate in
-any way that your Modified License is the "Academic Free License" or "AFL" and
-you may not use those names in the name of your Modified License; (ii) You
-must replace the notice specified in the first paragraph above with the notice
-"Licensed under <insert your license name here>" or with a notice of your own
-that is not confusingly similar to the notice in this License; and (iii) You
-may not claim that your original works are open source software unless your
-Modified License has been approved by Open Source Initiative (OSI) and You
-comply with its license review and certification process.

-Open Software License ("OSL") v 3.0
-###################################
-
-This Open Software License (the "License") applies to any original work of
-authorship (the "Original Work") whose owner (the "Licensor") has placed the
-following licensing notice adjacent to the copyright notice for the Original
-Work:
-
-*Licensed under the Open Software License version 3.0*
-
-
-*****************************
-1) Grant of Copyright License
-*****************************
-
-Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
-license, for the duration of the copyright, to do the following:
-
-	*a)* to reproduce the Original Work in copies, either alone or as part of
-	a collective work;
-
-	*b)* to translate, adapt, alter, transform, modify, or arrange the
-	Original Work, thereby creating derivative works ("Derivative Works")
-	based upon the Original Work;
-
-	*c)* to distribute or communicate copies of the Original Work and
-	Derivative Works to the public, *with the proviso that copies of Original
-	Work or Derivative Works that You distribute or communicate shall be
-	licensed under this Open Software License*;
-
-	*d)* to perform the Original Work publicly; and
-
-	*e)* to display the Original Work publicly.
-
-
-**************************
-2) Grant of Patent License
-**************************
-
-Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
-license, under patent claims owned or controlled by the Licensor that are
-embodied in the Original Work as furnished by the Licensor, for the duration
-of the patents, to make, use, sell, offer for sale, have made, and import the
-Original Work and Derivative Works.
-
-
-*******************************
-3) Grant of Source Code License
-*******************************
-
-The term "Source Code" means the preferred form of the Original Work for
-making modifications to it and all available documentation describing how to
-modify the Original Work. Licensor agrees to provide a machine-readable copy
-of the Source Code of the Original Work along with each copy of the Original
-Work that Licensor distributes. Licensor reserves the right to satisfy this
-obligation by placing a machine-readable copy of the Source Code in an
-information repository reasonably calculated to permit inexpensive and
-convenient access by You for as long as Licensor continues to distribute the
-Original Work.
-
-
-********************************
-4) Exclusions From License Grant
-********************************
-
-Neither the names of Licensor, nor the names of any contributors to the
-Original Work, nor any of their trademarks or service marks, may be used to
-endorse or promote products derived from this Original Work without express
-prior permission of the Licensor. Except as expressly stated herein, nothing
-in this License grants any license to Licensor's trademarks, copyrights,
-patents, trade secrets or any other intellectual property. No patent license
-is granted to make, use, sell, offer for sale, have made, or import
-embodiments of any patent claims other than the licensed claims defined in
-Section 2) No license is granted to the trademarks of Licensor even if such
-marks are included in the Original Work. Nothing in this License shall be
-interpreted to prohibit Licensor from licensing under terms different from
-this License any Original Work that Licensor otherwise would have a right to
-license.
-
-
-**********************
-5) External Deployment
-**********************
-
-The term "External Deployment" means the use, distribution, or communication
-of the Original Work or Derivative Works in any way such that the Original
-Work or Derivative Works may be used by anyone other than You, whether those
-works are distributed or communicated to those persons or made available as an
-application intended for use over a network. As an express condition for the
-grants of license hereunder, You must treat any External Deployment by You of
-the Original Work or a Derivative Work as a distribution under section 1(c).
-
-
-*********************
-6) Attribution Rights
-*********************
-
-You must retain, in the Source Code of any Derivative Works that You create,
-all copyright, patent, or trademark notices from the Source Code of the
-Original Work, as well as any notices of licensing and any descriptive text
-identified therein as an "Attribution Notice." You must cause the Source Code
-for any Derivative Works that You create to carry a prominent Attribution
-Notice reasonably calculated to inform recipients that You have modified the
-Original Work.
-
-
-****************************************************
-7) Warranty of Provenance and Disclaimer of Warranty
-****************************************************
-
-Licensor warrants that the copyright in and to the Original Work and the
-patent rights granted herein by Licensor are owned by the Licensor or are
-sublicensed to You under the terms of this License with the permission of the
-contributor(s) of those copyrights and patent rights. Except as expressly
-stated in the immediately preceding sentence, the Original Work is provided
-under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or
-implied, including, without limitation, the warranties of non-infringement,
-merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE
-QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY
-constitutes an essential part of this License. No license to the Original Work
-is granted by this License except under this disclaimer.
-
-
-**************************
-8) Limitation of Liability
-**************************
-
-Under no circumstances and under no legal theory, whether in tort (including
-negligence), contract, or otherwise, shall the Licensor be liable to anyone
-for any indirect, special, incidental, or consequential damages of any
-character arising as a result of this License or the use of the Original Work
-including, without limitation, damages for loss of goodwill, work stoppage,
-computer failure or malfunction, or any and all other commercial damages or
-losses. This limitation of liability shall not apply to the extent applicable
-law prohibits such limitation.
-
-
-*****************************
-9) Acceptance and Termination
-*****************************
-
-If, at any time, You expressly assented to this License, that assent indicates
-your clear and irrevocable acceptance of this License and all of its terms and
-conditions. If You distribute or communicate copies of the Original Work or a
-Derivative Work, You must make a reasonable effort under the circumstances to
-obtain the express assent of recipients to the terms of this License. This
-License conditions your rights to undertake the activities listed in Section
-1, including your right to create Derivative Works based upon the Original
-Work, and doing so without honoring these terms and conditions is prohibited
-by copyright law and international treaty. Nothing in this License is intended
-to affect copyright exceptions and limitations (including "fair use" or "fair
-dealing"). This License shall terminate immediately and You may no longer
-exercise any of the rights granted to You by this License upon your failure to
-honor the conditions in Section 1(c).
-
-
-*********************************
-10) Termination for Patent Action
-*********************************
-
-This License shall terminate automatically and You may no longer exercise any
-of the rights granted to You by this License as of the date You commence an
-action, including a cross-claim or counterclaim, against Licensor or any
-licensee alleging that the Original Work infringes a patent. This termination
-provision shall not apply for an action alleging patent infringement by
-combinations of the Original Work with other software or hardware.
-
-
-*****************************************
-11) Jurisdiction, Venue and Governing Law
-*****************************************
-
-Any action or suit relating to this License may be brought only in the courts
-of a jurisdiction wherein the Licensor resides or in which Licensor conducts
-its primary business, and under the laws of that jurisdiction excluding its
-conflict-of-law provisions. The application of the United Nations Convention
-on Contracts for the International Sale of Goods is expressly excluded. Any
-use of the Original Work outside the scope of this License or after its
-termination shall be subject to the requirements and penalties of copyright or
-patent law in the appropriate jurisdiction. This section shall survive the
-termination of this License.
-
-
-*******************
-12) Attorneys' Fees
-*******************
-
-In any action to enforce the terms of this License or seeking damages relating
-thereto, the prevailing party shall be entitled to recover its costs and
-expenses, including, without limitation, reasonable attorneys' fees and costs
-incurred in connection with such action, including any appeal of such action.
-This section shall survive the termination of this License.
-
-
-*****************
-13) Miscellaneous
-*****************
-
-If any provision of this License is held to be unenforceable, such provision
-shall be reformed only to the extent necessary to make it enforceable.
-
-
-***************************************
-14) Definition of "You" in This License
-***************************************
-
-"You" throughout this License, whether in upper or lower case, means an
-individual or a legal entity exercising rights under, and complying with all
-of the terms of, this License. For legal entities, "You" includes any entity
-that controls, is controlled by, or is under common control with you. For
-purposes of this definition, "control" means (i) the power, direct or
-indirect, to cause the direction or management of such entity, whether by
-contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the
-outstanding shares, or (iii) beneficial ownership of such entity.
-
-
-****************
-15) Right to Use
-****************
-
-You may use the Original Work in all ways not otherwise restricted or
-conditioned by this License or by law, and Licensor promises not to interfere
-with or be responsible for such uses by You.
-
-
-********************************
-16) Modification of This License
-********************************
-
-This License is Copyright © 2005 Lawrence Rosen. Permission is granted to
-copy, distribute, or communicate this License without modification. Nothing in
-this License permits You to modify this License as applied to the Original
-Work or to Derivative Works. However, You may modify the text of this License
-and copy, distribute or communicate your modified version (the "Modified
-License") and apply it to other original works of authorship subject to the
-following conditions: (i) You may not indicate in any way that your Modified
-License is the "Open Software License" or "OSL" and you may not use those
-names in the name of your Modified License; (ii) You must replace the notice
-specified in the first paragraph above with the notice "Licensed under <insert
-your license name here>" or with a notice of your own that is not confusingly
-similar to the notice in this License; and (iii) You may not claim that your
-original works are open source software unless your Modified License has been
-approved by Open Source Initiative (OSI) and You comply with its license
-review and certification process.

 Bug fixes for 3.0

From f7c8ea2dafc9c007c5363ed33e323344bee18944 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3193/5397] Revert to default sphinx theme

Remove dependency on EllisLab corporate theme - that is not appropriate for us.
Reverted to default Sphinx theme, with a couple of options, which have the side-effect of adding back document tree navigation (next/previous) and collapsible menu (albeit a sidebar not a top one).

Closes #2605 and closes #2354, for now.
This is not a proper styling - that is a separate issue!

       - Added support for passing a custom database object to the loader.
       - Added support for passing custom table attributes (such as ``ENGINE`` for MySQL) to ``create_table()``.
       - Added support for usage of the *FIRST* clause in ``add_column()`` for MySQL and CUBRID.
+      - Added partial support for field columns (MySQL, PostgreSQL, Oracle).
       - Deprecated ``add_column()``'s third method. *AFTER* clause should now be added to the field definition array instead.

Subject: [PATCH 3223/5397] Better Issue report writeup

Documentation: contributing to CodeIgniter...
Added a reminder about issues vs support, and some tips for a good issue report.
This was suggested by a user on the forum, and seems like a good idea.

 Request, which is done by "Forking" the main repository and committing to your

+*******
+Support
+*******
+
+Note that GitHub is not for general support questions!
+
+If you are having trouble using a feature of CodeIgniter, ask for help on the forum.
+
+If you are wondering if you are using 
+something correctly or if you have found a bug, ask on the forum first.
+
+***************************
+Tips for a Good Issue Report
+***************************
+
+Use a descriptive subject line (eg parser library chokes on commas) rather than a vague one (eg. your code broke).
+
+Address a single issue in a report.
+
+Identify the CodeIgniter version (eg 3.0-develop) and the component if you know it (eg. parser library)
+
+Explain what you expected to happen, and what did happen.
+Include error messages and stacktrace, if any.
+
+Include short code segments if they help to explain.
+Use a pastebin or dropbox facility to include longer segments of code or screenshots - do not include them in the issue report itself.
+This means setting a reasonable expiry for those, until the issue is resolved or closed.
+
+If you know how to fix the issue, you can do so in your own fork & branch, and submit a pull request.
+The issue report information above should be part of that.
+
+If your issue report can describe the steps to reproduce the problem, that is great.
+If you can include a unit test that reproduces the problem, that is even better, as it gives whoever is fixing
+it a clearer target!

+

+Internationalization
+********************
+
+The Language class in CodeIgniter is meant to provide an easy and lightweight way to support multiple
+languages in your application. It is not meant to be a full implementation of what is commonly called
+`internationalization and localization <http://en.wikipedia.org/wiki/Internationalization_and_localization>`_.
+
+We use the term "idiom" to refer to a language using its common name, 
+rather than using any of the international standards, such as "en", "en-US", or "en-CA-x-ca" for English
+and some of its variants.
+
+.. note:: There is nothing to prevent you from using those abbreviations in your application!

Subject: [PATCH 3265/5397] User Guide update - Query Builder (fixes #2512)

1) Changed the grouping for better readability, in the query builder writeup
2) Added return value descriptors for all methods
3) Added default setting to query builder configuration writeup.

The TOC sidebar is much better than before, though still a bit messy. This will need fixing with the sphinx theme update, being done separately.

       -  Changed default value of the ``$xss_clean`` parameter to NULL for all methods that utilize it, the default value is now determined by the ``$config['global_xss_filtering']`` setting.
       -  Added method ``post_get()`` and changed ``get_post()`` to search in GET data first. Both methods' names now properly match their GET/POST data search priorities.
       -  Changed method ``_fetch_from_array()`` to parse array notation in field name.
+      -  Changed method ``_fetch_from_array()`` to allow retrieving multiple fields at once by passing $index as an array.
       -  Added an option for ``_clean_input_keys()`` to return FALSE instead of terminating the whole script.
       -  Deprecated the ``is_cli_request()`` method, it is now an alias for the new :func:`is_cli()` common function.
       -  Added an ``$xss_clean`` parameter to method ``user_agent()`` and removed the ``$user_agent`` property.

Subject: [PATCH 3325/5397] Remove output minifier

This feature has proven to be problematic and it's not nearly
as flexible as a dedicated minifier library like Minify
(http://www.minifier.org/, https://github.com/matthiasmullie/minify).

The same results in terms of saving traffic can also be achievied via
gzip compression (which should also be done on the httpd level, but we
also support anyway) and stuff like mod_pagespeed.

Reverts PR #965

Related issues as a track record proving how problematic this has been:

#2078 #1499 #2163 #2092 #2387 #2637 #2710 #2120 #2171 #2631 #2326 #2795
#2791 #2772

Additionally, the count of contributors suggesting that the only way
to fix the minifier problems is to remove it, is around the same as
the count of people suggesting the feature to be implemented in the
first place. It was experimental anyway ... the experiment failed.

+###################
+DB Driver Reference
+###################
+
+This is the platform-independent base DB implementation class.
+This class will not be called directly. Rather, the adapter
+class for the specific database will extend and instantiate it.
+
+The how-to material for this has been split over several articles.
+This article is intended to be a reference for them.
+
+.. class:: CI_DB_driver
+
+	.. method:: initialize()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Initialize Database Settings; 
+                establish a connection to the database.
+
+	.. method:: db_pconnect()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Establish a persistent database connection
+
+	.. method:: reconnect()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Keep / reestablish the db connection if no queries have been
+                sent for a length of time exceeding the server's idle timeout.
+
+                This is only available in drivers that support it.
+
+	.. method:: db_select()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Select database
+
+	.. method:: db_set_charset($charset)
+
+		:param	string	$charset: Character set name
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Set client character set
+
+	.. method:: platform()
+
+		:returns:	Platform name
+		:rtype:	string
+
+		The name of the platform in use (mysql, mssql, etc...)
+
+	.. method:: version()
+
+		:returns:	The version of the database being used.
+		:rtype:	string
+
+		Database version number
+
+	.. method:: query($sql[, $binds = FALSE[, $return_object = NULL]]])
+
+		:param	string	$sql: The SQL statement to execute
+		:param	array	$binds: An array of binding data
+		:param	bool	$return_object: Character set name
+		:returns:	True on "update" success, DB_result object on "query" success, FALSE on failure
+		:rtype:	mixed
+
+		Execute the query
+
+                Accepts an SQL string as input and returns a result object 
+                upon
+                successful execution of a "read" type query. Returns boolean 
+                TRUE
+                upon successful execution of a "write" type query. 
+                Returns boolean
+                FALSE upon failure, and if the $db_debug variable is set 
+                to TRUE
+                will raise an error.
+
+	.. method:: load_rdriver()
+
+		:returns:	The DB_result object appropriate for the driver in use
+		:rtype:	DB_result
+
+		Load the result drivers
+
+	.. method:: simple_query($sql)

+		:rtype:	mixed
+
+		Simple Query
+
+                This is a simplified version of the query() function. Internally
+                we only use it when running transaction commands since they do
+                not require all the features of the main query() function.
+
+	.. method:: trans_off()
+
+		:rtype:	void
+
+		Disable Transactions.
+
+                This permits transactions to be disabled at run-time.

+		:rtype:	void
+
+		Enable/disable Transaction Strict Mode.

+                groups of
+                transactions, if one group fails all groups will be rolled back.
+                If strict mode is disabled, each group is treated autonomously, 
+                meaning
+                a failure of one group will not affect any others.
+
+	.. method:: trans_start([$test_mode = FALSE[)
+
+		:param	boolean	$test_mode: TRUE for testing mode
+		:rtype:	void
+
+		Start Transaction.
+
+	.. method:: trans_complete()
+
+		:rtype:	void
+
+		Complete Transaction.
+
+	.. method:: trans_status()
+
+                :returns:   TRUE if the transaction succeeded, FALSE if it failed
+		:rtype:	boolean
+
+		Lets you retrieve the transaction flag to determine if it
+                has failed.
+
+	.. method:: compile_binds($sql, $binds)
+
+		:param	string	$sql: The SQL statement 
+		:param	array	$binds: An array of binding data
+		:returns:	The updated SQL statement
+		:rtype:	string
+
+		Compile Bindings
+
+	.. method:: is_write_type($sql)
+
+		:param	string	$sql: The SQL statement 
+		:returns:	TRUE if the SQL statement is a "write" type of statement
+		:rtype:	boolean
+
+		Determines if a query is a "write" type.
+
+	.. method:: elapsed_time([$decimals = 6])
+
+		:param	int	$decimals: The number of decimal places
+		:returns:	The aggregate query elapsed time, in microseconds
+		:rtype:	string
+
+		Calculate the aggregate query elapsed time.
+
+	.. method:: total_queries()
+
+		:returns:	The total number of queries
+		:rtype:	int
+
+		Returns the total number of queries.
+
+	.. method:: last_query()
+
+		:returns:	The last query executed
+		:rtype:	string
+
+		Returns the last query that was executed.
+
+	.. method:: escape($str)
+
+		:param	string	$str: The string to work with
+		:returns:	The escaped string
+		:rtype:	mixed
+
+		"Smart" Escape String.

+                a couple functions in this class.
+                It takes a column or table name (optionally with an alias) 
+                and inserts
+                the table prefix onto it. Some logic is necessary in order 
+                to deal with
+                column names that include the path. Consider a query like this::
+                
+                        SELECT * FROM hostname.database.table.column AS c FROM hostname.database.table
+                
+                Or a query with aliasing::
+                
+                        SELECT m.member_id, m.member_name FROM members AS m
+                
+                Since the column name can include up to four segments 
+                (host, DB, table, column)
+                or also have an alias prefix, we need to do a bit of work 
+                to figure this out and
+                insert the table prefix (if it exists) in the proper position, 
+                and escape only
+                the correct identifiers.

+#############################
+Upgrading from 2.1.4 to 2.2.0
+#############################
+
+.. note:: The :doc:`Encrypt Class <libraries/encrypt>` now requires the
+	Mcrypt extension. If you were previously using the Encrypt Class
+	without Mcrypt, then this is a breaking change.  You must install
+	the Mcrypt extension in order to upgrade. For information on
+	installing Mcrypt please see the PHP `documentation
+	<http://php.net/manual/en/mcrypt.setup.php>`.
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace all files and directories in your "system" folder.
+
+.. note:: If you have any custom developed files in these folders please

Subject: [PATCH 3339/5397] User Guide Tuning

Adjust the heading levels in the writeups for the input, loader, security and unit testing libraries, to match the other library writeups.
Specifically, the class reference section in each of these was appearing as a sub-level in the toctree, when it should be at the same level.

+We've made that mistake ourselves with our automatic and global XSS cleaning

+generally validates *input* data, the 'xss_clean' rule simply doesn't
+belong in it.

+If you really, really need to apply that rule, you should now also load the

+``xss_clean()`` as a regular function and therefore can be also used as

 Initializing a Session
 ======================

 To initialize the Session class manually in your controller constructor,

-	$this->load->driver('session');
+	$this->load->library('session');
 
 Once loaded, the Sessions library object will be available using::
 
 	$this->session
 
+.. important:: Because the :doc:`Loader Class <../loader>` is instantiated
+	by CodeIgniter's base controller, make sure to call
+	``parent::__construct()`` before trying to load a library from
+	inside a controller constructor.
+
 How do Sessions work?
 =====================
 
 When a page is loaded, the session class will check to see if valid
-session data exists in the user's session. If sessions data does **not**
-exist (or if it has expired) a new session will be created and saved.
-If a session does exist, its information will be updated. With each update,

+**not** exist (or if it doesn't match one stored on the server or has
+expired) a new session will be created and saved.
+
+If a valid session does exist, its information will be updated. With each
+update, the session ID may be regenerated if configured to do so.
 
 It's important for you to understand that once initialized, the Session
 class runs automatically. There is nothing you need to do to cause the

+data, but the process of reading, writing, and updating a session is
+automatic.
+
+.. note:: Under CLI, the Session library will automatically halt itself,
+	as this is a concept based entirely on the HTTP protocol.
 
 What is Session Data?
 =====================
 
-A *session*, as far as CodeIgniter is concerned, is simply an array
-containing the following information:
-
--  The user's unique Session ID (this is a statistically random string
-   with very strong entropy, hashed with MD5 for portability, and
-   regenerated (by default) every five minutes)
--  The user's IP Address
--  The user's User Agent data (the first 120 characters of the browser
-   data string)
--  The "last activity" time stamp.
-
-The above data is stored in a cookie as a serialized array with this
-prototype::
-
-	[array]
-	(
-		'session_id'    => random hash,
-		'ip_address'    => 'string - user IP address',
-		'user_agent'    => 'string - user agent data',
-		'last_activity' => timestamp
-	)
-
-.. note:: Sessions are only updated every five minutes by default to
-	reduce processor load. If you repeatedly reload a page you'll notice
-	that the "last activity" time only updates if five minutes or more has
-	passed since the last time the cookie was written. This time is
-	configurable by changing the $config['sess_time_to_update'] line in
-	your system/config/config.php file.
+Session data is simply an array associated with a particular session ID
+(cookie).
+
+If you've used sessions in PHP before, you should be familiar with PHP's
+`$_SESSION superglobal <http://php.net/manual/en/reserved.variables.session.php>`_
+(if not, please read the content on that link).
+
+CodeIgniter gives access to its session data through the same means, as it
+uses the session handlers' mechanism provided by PHP. Using session data is
+as simple as manipulating (read, set and unset values) the ``$_SESSION``
+array.
+
+In addition, CodeIgniter also provides 2 special types of session data
+that are further explained below: flashdata and tempdata.
+
+.. note:: In previous versions, regular session data in CodeIgniter was
+	referred to as 'userdata'. Have this in mind if that term is used
+	elsewhere in the manual. Most of it is written to explain how
+	the custom 'userdata' methods work.
 
 Retrieving Session Data
 =======================
 
-Any piece of information from the session array is available using the
-following function::
+Any piece of information from the session array is available through the
+``$_SESSION`` superglobal::
+
+	$_SESSION['item']
+
+Or through the magic getter::
+
+	$this->session->item
+
+And for backwards compatibility, through the ``userdata()`` method::
 
 	$this->session->userdata('item');
 
-Where item is the array index corresponding to the item you wish to
-fetch. For example, to fetch the session ID you will do this::
+Where item is the array key corresponding to the item you wish to fetch.
+For example, to assign a previously stored 'name' item to the ``$name``
+variable, you will do this::
+
+	$name = $_SESSION['name'];
+
+	// or:
 
-	$session_id = $this->session->userdata('session_id');
+	$name = $this->session->name
 
-.. note:: The function returns NULL if the item you are
-	trying to access does not exist.
+	// or:
+
+	$name = $this->session->userdata('name');
+
+.. note:: The ``userdata()`` method returns NULL if the item you are trying
+	to access does not exist.
 
 If you want to retrieve all of the existing userdata, you can simply
-omit the item key parameter::
+omit the item key (magic getter only works for properties)::
 
-	$this->session->userdata();
+	$_SESSION
 
-	/**

-Adding Custom Session Data
-==========================
+	// or:
+
+	$this->session->userdata();
 
-A useful aspect of the session array is that you can add your own data
-to it and it will be stored in the user's cookie. Why would you want to
-do this? Here's one example:
+Adding Session Data

 Let's say a particular user logs into your site. Once authenticated, you

+data globally available to you without having to run a database query when

+
+You can simply assign data to the ``$_SESSION`` array, as with any other
+variable. Or as a property of ``$this->session``.
 
-To add your data to the session array involves passing an array
-containing your new data to this function::
+Alternatively, the old method of assigning it as "userdata" is also
+available. That however passing an array containing your new data to the
+``set_userdata()`` method::
 
 	$this->session->set_userdata($array);
 
-Where $array is an associative array containing your new data. Here's an

+
+Or you can call ``has_userdata()``::
 
 	$this->session->has_userdata('some_name');
 
 Removing Session Data
 =====================
 
-Just as set_userdata() can be used to add information into a session,
-unset_userdata() can be used to remove it, by passing the session key.
-For example, if you wanted to remove 'some_name' from your session
-information::
+Just as with any other variable, unsetting a value in ``$_SESSION`` can be
+done through ``unset()``::
 
-	$this->session->unset_userdata('some_name');
+	unset($_SESSION['some_name']);
 
+	// or multiple values:
 
-This function can also be passed an associative array of items to unset.
+	unset(
+		$_SESSION['some_name'],
+		$_SESSION['another_name']
+	);
 
-::
+Also, just as ``set_userdata()`` can be used to add information to a
+session, ``unset_userdata()`` can be used to remove it, by passing the
+session key. For example, if you wanted to remove 'some_name' from your
+session data array::
+
+	$this->session->unset_userdata('some_name');
+
+This method also accepts an associative array of items to unset::
 
 	$array_items = array('username' => '', 'email' => '');
 
 	$this->session->unset_userdata($array_items);

 Flashdata
 =========
 
 CodeIgniter supports "flashdata", or session data that will only be
-available for the next server request, and are then automatically
-cleared. These can be very useful, and are typically used for
-informational or status messages (for example: "record 2 deleted").
+available for the next request, and is then automatically cleared.
+
+This can be very useful, especially for one-time informational, error or
+status messages (for example: "Record 2 deleted").
+
+It should be noted that flashdata variables are regular session vars,
+only marked in a specific way under the '__ci_vars' key (please don't touch
+that one, you've been warned).
 
-.. note:: Flash variables are prefaced with "flash\_" so avoid this prefix
-	in your own session names.
+To mark an existing item as "flashdata"::
+
+	$this->session->mark_as_flash('item');
+
+If you want to mark multiple items as flashdata, simply pass the keys as an
+array::
+
+	$this->session->mark_as_flash(array('item', 'item2'));
 
 To add flashdata::
 
-	$this->session->set_flashdata('item', 'value');
+	$_SESSION['item'] = 'value';
+	$this->session->mark_as_flash('item');
 
+Or alternatively, using the ``set_flashdata()`` method::
+
+	$this->session->set_flashdata('item', 'value');
 
 You can also pass an array to ``set_flashdata()``, in the same manner as
 ``set_userdata()``.
 
-To read a flashdata variable::
+Reading flashdata variables is the same as reading regular session data
+through ``$_SESSION``::
+
+	$_SESSION['item']
+
+.. important:: The ``userdata()`` method will NOT return flashdata items.
+
+However, if you want to be sure that you're reading "flashdata" (and not
+any other kind), you can also use the ``flashdata()`` method::
 
 	$this->session->flashdata('item');
 
-An array of all flashdata can be retrieved as follows::
+Or to get an array with all flashdata, simply omit the key parameter::
 
 	$this->session->flashdata();
 
+.. note:: The ``flashdata()`` method returns NULL if the item cannot be

+
+Accessing session metadata
+==========================
+
+In previous CodeIgniter versions, the session data array included 4 items
+by default: 'session_id', 'ip_address', 'user_agent', 'last_activity'.
+
+This was due to the specifics of how sessions worked, but is now no longer
+necessary with our new implementation. However, it may happen that your
+application relied on these values, so here are alternative methods of
+accessing them::
+
+  - session_id: ``session_id()``
+  - ip_address: ``$_SERVER['REMOTE_ADDR']``
+  - user_agent: ``$this->input->user_agent()`` (unused by sessions)
+  - last_activity: Depends on the storage, no straightforward way. Sorry!
 
 Session Preferences
 ===================
 
+CodeIgniter will usually make everything work out of the box. However,
+Sessions are a very sensitive component of any application, so some
+careful configuration must be done. Please take your time to consider
+all of the options and their effects.

 You'll find the following Session related preferences in your

 Session Drivers
 ===============
 
-By default, the `Cookie Driver`_ is loaded when a session is initialized.
-However, any valid driver may be selected with the $config['sess_driver']
-line in your config.php file.
-
-The session driver library comes with the cookie and native drivers
-installed, and `Custom Drivers`_ may also be installed by the user.
-
-Typically, only one driver will be used at a time, but CodeIgniter does
-support loading multiple drivers. If a specific valid driver is called, it
-will be automatically loaded. Or, an additional driver may be explicitly
-loaded by ``calling load_driver()``::
-
-	$this->session->load_driver('native');
-
-The Session library keeps track of the most recently selected driver to call
-for driver methods. Normally, session class methods are called directly on
-the parent class, as illustrated above. However, any methods called through
-a specific driver will select that driver before invoking the parent method.
-
-So, alternation between multiple drivers can be achieved by specifying which
-driver to use for each call::
-
-	$this->session->native->set_userdata('foo', 'bar');
-
-	$this->session->cookie->userdata('foo');
-
-	$this->session->native->unset_userdata('foo');
-
-Notice in the previous example that the *native* userdata value 'foo'
-would be set to 'bar', which would NOT be returned by the call for
-the *cookie* userdata 'foo', nor would the *cookie* value be unset by
-the call to unset the *native* 'foo' value. The drivers maintain independent
-sets of values, regardless of key names.
-
-A specific driver may also be explicitly selected for use by pursuant
-methods with the ``select_driver()`` call::
-
-	$this->session->select_driver('native');
-
-	$this->session->userdata('item');	// Uses the native driver
-
-Cookie Driver
--------------
-
-The Cookie driver stores session information for each user as serialized
-(and optionally encrypted) data in a cookie. It can also store the session
-data in a database table for added security, as this permits the session ID
-in the user's cookie to be matched against the stored session ID. By default
-only the cookie is saved. If you choose to use the database option you'll
-need to create the session table as indicated below.
-
-If you have the encryption option enabled, the serialized array will be
-encrypted before being stored in the cookie, making the data highly
-secure and impervious to being read or altered by someone. More info
-regarding encryption can be :doc:`found here <encryption>`, although
-the Session class will take care of initializing and encrypting the data
-automatically.
-
-.. note:: Even if you are not using encrypted sessions, you must set
-	an :doc:`encryption key <./encryption>` in your config file which is used
-	to aid in preventing session data manipulation.
-
-.. note:: Cookies can only hold 4KB of data, so be careful not to exceed
-	the capacity. The encryption process in particular produces a longer
-	data string than the original so keep careful track of how much data you
-	are storing.
-
-Saving Session Data to a Database
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-While the session data array stored in the user's cookie contains a
-Session ID, unless you store session data in a database there is no way
-to validate it. For some applications that require little or no
-security, session ID validation may not be needed, but if your
-application requires security, validation is mandatory. Otherwise, an
-old session could be restored by a user modifying their cookies.
-
-When session data is available in a database, every time a valid session
-is found in the user's cookie, a database query is performed to match
-it. If the session ID does not match, the session is destroyed. Session
-IDs can never be updated, they can only be generated when a new session
-is created.
-
-In order to store sessions, you must first create a database table for
-this purpose. Here is the basic prototype (for MySQL) required by the
-session class::
-
-	CREATE TABLE IF NOT EXISTS  `ci_sessions` (
-		session_id varchar(40) DEFAULT '0' NOT NULL,
-		ip_address varchar(45) DEFAULT '0' NOT NULL,
-		user_agent varchar(120) NOT NULL,
-		last_activity int(10) unsigned DEFAULT 0 NOT NULL,
-		user_data text NOT NULL,
-		PRIMARY KEY (session_id, ip_address, user_agent),
-		KEY `last_activity_idx` (`last_activity`)
+As already mentioned, the Session library comes with 4 drivers, or storage
+engines, that you can use:
+
+  - files
+  - database
+  - redis
+  - memcached
+
+By default, the `Files Driver`_ will be used when a session is initialized,
+because it is the most safe choice and is expected to work everywhere
+(virtually every environment has a file system).
+
+However, any other driver may be selected via the ``$config['sess_driver']``
+line in your **application/config/config.php** file, if you chose to do so.
+Have it in mind though, every driver has different caveats, so be sure to
+get yourself familiar with them (below) before you make that choice.
+
+In addition, you may also create and use `Custom Drivers`_, if the ones
+provided by default don't satisfy your use case.
+
+.. note:: In previous CodeIgniter versions, a different, "cookie driver"
+	was the only option and we have received negative feedback on not
+	providing that option. While we do listen to feedback from the
+	community, we want to warn you that it was dropped because it is
+	**unsafe** and we advise you NOT to try to replicate it via a
+	custom driver.
+
+Files Driver
+------------
+
+The 'files' driver uses your file system for storing session data.
+
+It can safely be said that it works exactly like PHP's own default session
+implementation, but in case this is an important detail for you, have it
+mind that it is in fact not the same code and it has some limitations
+(and advantages).
+
+To be more specific, it doesn't support PHP's `directory level and mode
+formats used in session.save_path
+<http://php.net/manual/en/session.configuration.php#ini.session.save-path>`_,
+and it has most of the options hard-coded for safety. Instead, only
+absolute paths are supported for ``$config['sess_save_path']``.
+
+Another important thing that you should know, is to make sure that you
+don't use a publicly-readable or shared directory for storing your session
+files. Make sure that *only you* have access to see the contents of your
+chosen *sess_save_path* directory. Otherwise, anybody who can do that, can
+also steal any of the current sessions (also known as "session fixation"
+attack).
+
+On UNIX-like operating systems, this is usually achieved by setting the
+0600 mode permissions on that directory via the `chmod` command, which
+allows only the directory's owner to perform read and write operations on
+it. But be careful because the system user *running* the script is usually
+not your own, but something like 'www-data' instead, so only setting those
+permissions will probable break your application.
+
+Instead, you should do something like this, depending on your environment
+::
+
+	mkdir /<path to your application directory>/sessions/
+	chmod 0600 /<path to your application directory>/sessions/
+	chown www-data /<path to your application directory>/sessions/
+
+Bonus Tip
+^^^^^^^^^
+
+Some of you will probably opt to choose another session driver because
+file storage is usually slower. This is only half true.
+
+A very basic test will probably trick you into believing that an SQL
+database is faster, but in 99% of the cases, this is only true while you
+only have a few current sessions. As the sessions count and server loads
+increase - which is the time when it matters - the file system will
+consistently outperform almost all relational database setups.
+
+In addition, if performance is your only concern, you may want to look
+into using `tmpfs <http://eddmann.com/posts/storing-php-sessions-file-caches-in-memory-using-tmpfs/>`_,
+(warning: external resource), which can make your sessions blazing fast.
+
+Database Driver
+---------------
+
+The 'database' driver uses a relational database such as MySQL or
+PostgreSQL to store sessions. This is a popular choice among many users,
+because it allows the developer easy access to the session data within
+an application - it is just another table in your database.
+
+However, there are some conditions that must be met:
+
+  - Only your **default** database connection (or the one that you access
+    as ``$this->db`` from your controllers) can be used.
+  - You can NOT use a persistent connection.
+  - You must have the :doc:`Query Builder </database/query_builder>`
+    enabled.
+
+In order to use the 'database' session driver, you must also create this
+table that we already mentioned and then set it as your
+``$config['sess_save_path']`` value.
+For example, if you would like to use 'ci_sessions' as your table name,
+you would do this:
+
+	$config['sess_driver'] = 'database';
+	$config['sess_save_path'] = 'ci_sessions';
+
+.. note:: If you've upgraded from a previous version of CodeIgniter and
+	you don't have 'sess_save_path' configured, then the Session
+	library will look for the old 'sess_table_name' setting and use
+	it instead. Please don't rely on this behavior as it will get
+	removed in the future.
+
+And then of course, create the database table ...
+
+For MySQL::
+
+	CREATE TABLE IF NOT EXISTS `ci_sessions` (
+		`session_id` varchar(40) NOT NULL,
+		`ip_address` varchar(45) NOT NULL,
+		`timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
+		`data` blob DEFAULT '' NOT NULL,
+		PRIMARY KEY (session_id, ip_address),
+		KEY `ci_sessions_timestamp` (`timestamp`)
 	);
 
-Or if you're using PostgreSQL::
+For PostgreSQL::
 
-	CREATE TABLE  ci_sessions (
-		session_id varchar(40) DEFAULT '0' NOT NULL,
-		ip_address varchar(45) DEFAULT '0' NOT NULL,
-		user_agent varchar(120) NOT NULL,
-		last_activity bigint DEFAULT 0 NOT NULL,
-		user_data text NOT NULL,
-		PRIMARY KEY (session_id)
+	CREATE TABLE "ci_sessions" (
+		"session_id" varchar(40) NOT NULL,
+		"ip_address" varchar(45) NOT NULL,
+		"timestamp" bigint DEFAULT 0 NOT NULL,
+		"data" text DEFAULT '' NOT NULL,
+		PRIMARY KEY ("session_id")
 	);
 
-	CREATE INDEX last_activity_idx ON ci_sessions(last_activity);
+	CREATE INDEX "ci_sessions_timestamp" ON "ci_sessions" ("timestamp");
+
+However, if you want to turn on the *sess_match_ip* setting, you should
+also do the following, after creating the table::
+
+	// Works both on MySQL and PostgreSQL
+	ALTER TABLE ci_sessions ADD CONSTRAINT ci_sessions_id_ip UNIQUE (session_id, ip_address);
+
+.. important:: Only MySQL and PostgreSQL databases are officially
+	supported, due to lack of locking mechanisms on other platforms.
+	Using sessions without locks can cause all sorts of problems,
+	especially with heavy usage of AJAX, and we will not support
+	such cases.
+
+Redis Driver
+------------
+
+Redis is a storage engine typically used for caching and popular because
+of its high performance, which is also probably your reason to use the
+'redis' session driver.
+
+The downside is that it is not as ubiquitous as relational databases and
+requires the `phpredis <https://github.com/nicolasff/phpredis>`_ PHP
+extension to be installed on your system, and that one doesn't come
+bundled with PHP.
+Chances are, you're only be using the 'redis' driver only if you're already
+both familiar with Redis and using it for other purposes.
+
+Just as with the 'files' and 'database' drivers, you must also configure
+the storage location for your sessions via the
+``$config['sess_save_path']`` setting.
+The format here is a bit different and complicated at the same time. It is
+best explained by the *phpredis* extension's README file, so we'll simply
+link you to it:
+
+	https://github.com/phpredis/phpredis#php-session-handler
+
+.. warning:: CodeIgniter's Session library does NOT use the actual 'redis'
+	``session.save_handler``. Take note **only** of the path format in
+	the link above.
 
-.. note:: By default the table is called ci_sessions, but you can name
-	it anything you want as long as you update the
-	*application/config/config.php* file so that it contains the name
-	you have chosen. Once you have created your database table you
-	can enable the database option in your config.php file as follows::
+For the most common case however, a simple ``host:port`` pair should be
+sufficient::
 
-		$config['sess_use_database'] = TRUE;
+	$config['sess_driver'] = 'redis';
+	$config['sess_save_path'] = 'tcp://localhost:6379';
 
-	Once enabled, the Session class will store session data in the DB.
+Memcached Driver
+----------------
 
-	Make sure you've specified the table name in your config file as well::
+The 'memcached' driver is very similar to the 'redis' one in all of its
+properties, except perhaps for availability, because PHP's `Memcached
+<http://php.net/memcached>`_ extension is distributed via PECL and some
+Linux distrubutions make it available as an easy to install package.
 
-		$config['sess_table_name'] = 'ci_sessions';
+Other than that, and without any intentional bias towards Redis, there's
+not much different to be said about Memcached - it is also a popular
+product that is usually used for caching and famed for its speed.
 
-.. note:: The Cookie driver has built-in garbage collection which clears
-	out expired sessions so you do not need to write your own routine to do
-	it.
+However, it is worth noting that the only guarantee given by Memcached
+is that setting value X to expire after Y seconds will result in it being
+deleted after Y seconds have passed (but not necessarily that it won't
+expire earlier than that time). This happens very rarely, but should be
+considered as it may result in loss of sessions.
 
-Native Driver
--------------
+The ``$config['sess_save_path']`` format is fairly straightforward here,
+being just a ``host:port`` pair::
 
-The Native driver relies on native PHP sessions to store data in the
-$_SESSION superglobal array. All stored values continue to be available
-through $_SESSION, but flash- and temp- data items carry special prefixes.
+	$config['sess_driver'] = 'memcached';
+	$config['sess_save_path'] = 'localhost:11211';
+
+Bonus Tip
+^^^^^^^^^
+
+Multi-server configuration with an optional *weight* parameter as the
+third colon-separated (``:weight``) value is also supported, but we have
+to note that we haven't tested if that is reliable.
+
+If you want to experiment with this feature (on your own risk), simply
+separate the multiple server paths with commas::
+
+	// localhost will be given higher priority (5) here,
+	// compared to 192.0.2.1 with a weight of 1.
+	$config['sess_save_path'] = 'localhost:11211:5,192.0.2.1:11211:1';
 
 Custom Drivers
 --------------
 
-You may also :doc:`create your own <../general/creating_drivers>` custom
-session drivers. A session driver basically manages an array of name/value
-pairs with some sort of storage mechanism.
+You may also create your own, custom session drivers. However, have it in
+mind that this is typically not an easy task, as it takes a lot of
+knowledge to do it properly.
+
+You need to know not only how sessions work in general, but also how they
+work specifically in PHP, how the underlying storage mechanism works, how
+to handle concurrency, avoid deadlocks (but NOT through lack of locks) and
+last but not least - how to handle the potential security issues, which
+is far from trivial.
+
+Long story short - if you don't know how to do that already in raw PHP,
+you shouldn't be trying to do it within CodeIgniter either. You've been
+warned.
+
+If you only want to add some extra functionality to your sessions, just
+extend the base Session class, which is a lot more easier. Read the
+:doc:`Creating Libraries <../general/creating_libraries>` article to
+learn how to do that.
+
+Now, to the point - there are three general rules that you must follow
+when creating a session driver for CodeIgniter:
+
+  - Put your driver's file under **application/libraries/Session/drivers/**
+    and follow the naming conventions used by the Session class.
+
+    For example, if you were to create a 'dummy' driver, you would have
+    a ``Session_dummy_driver`` class name, that is declared in
+    *application/libraries/Session/drivers/Session_dummy_driver.php*.
 
-To make a new driver, extend CI_Session_driver. Overload the ``initialize()``
-method and read or create session data. Then implement a save handler to
-write changed data to storage (sess_save), a destroy handler to remove
-deleted data (sess_destroy), a regenerate handler to make a new session ID
-(sess_regenerate), and an access handler to expose the data (get_userdata).
-Your initial class might look like::
+  - Extend the ``CI_Session_driver`` class.
 
-	class CI_Session_custom extends CI_Session_driver {
+    This is just a basic class with a few internal helper methods. It is
+    also extendable like any other library, if you really need to do that,
+    but we are not going to explain how ... if you're familiar with how
+    class extensions/overrides work in CI, then you already know how to do
+    it. If not, well, you shouldn't be doing it in the first place.
 
-		protected function initialize()
+
+  - Implement the `SessionHandlerInterface
+    <http://php.net/sessionhandlerinterface>`_ interface.
+
+    .. note:: You may notice that ``SessionHandlerInterface`` is provided
+    	by PHP since version 5.4.0. CodeIgniter will automatically declare
+    	the same interface if you're running an older PHP version.
+
+    The link will explain why and how.
+
+So, based on our 'dummy' driver example above, you'd end up with something
+like this::
+
+	// application/libraries/Session/drivers/Session_dummy_driver.php:
+
+	class CI_Session_dummy_driver extends CI_Session_driver implements SessionHandlerInterface
+	{
+
+		public function __construct(&$params)
+		{
+			// DO NOT forget this
+			parent::__construct($params);
+
+			// Configuration & other initializations
+		}
+
+		public function open($save_path, $name)
 		{
-			// Read existing session data or create a new one
+			// Initialize storage mechanism (connection)
 		}
 
-		public function sess_save()
+		public function read($session_id)
 		{
-			// Save current data to storage
+			// Read session data (if exists), acquire locks
 		}
 
-		public function sess_destroy()
+		public function write($session_id, $session_data)
 		{
-			// Destroy the current session and clean up storage
+			// Create / update session data (it might not exist!)
 		}
 
-		public function sess_regenerate()
+		public function close()
 		{
-			// Create new session ID
+			// Free locks, close connections / streams / etc.
 		}
 
-		public function &get_userdata()
+		public function destroy($session_id)
 		{
-			// Return a reference to your userdata array
+			// Call close() method & destroy data for current session (order may differ)
+		}
+
+		public function gc($maxlifetime)
+		{
+			// Erase data for expired sessions
 		}
 
 	}
 
-Notice that ``get_userdata()`` returns a reference so the parent library is
-accessing the same array the driver object is using. This saves memory
-and avoids synchronization issues during usage.
+If you've done everything properly, you can now set your *sess_driver*
+configuration value to 'dummy' and use your own driver. Congratulations!
+
+***************
+Class Reference
+***************
 
-Put your driver in the libraries/Session/drivers folder anywhere in your
-package paths. This includes the application directory, the system directory,
-or any path you add with ``$CI->load->add_package_path()``. Your driver must be
-named CI_Session_<name>, and your filename must be Session_<name>.php,
-preferably also capitalized, such as::
+.. class:: CI_Session
 
-	CI_Session_foo in libraries/Session/drivers/Session_foo.php
+	.. method:: userdata([$key = NULL])
 
-Then specify the driver by setting 'sess_driver' in your config.php file or as a
-parameter when loading the CI_Session object::
+		:param	mixed	$key: Session item key or NULL
+		:returns:	Value of the specified item key, or an array of all userdata
+		:rtype:	mixed
 
-	$config['sess_driver'] = 'foo';

-*********************************************************
-Step 6: Convert your Session usage from library to driver
-*********************************************************
+*****************************************
+Step 6: Update your Session library usage
+*****************************************
 
-When you load (or autoload) the Session library, you must now load it as a driver instead of a library. This means
-calling ``$this->load->driver('session')`` instead of ``$this->load->library('session')`` and/or listing 'session'
-in ``$autoload['drivers']`` instead of ``$autoload['libraries']``.
+The :doc:`Session Library </libraries/session>` has been completely
+re-written in CodeIgniter 3 and now comes with a bunch of new features,
+but that also means that there are changes that you should make ...
 
-With the change from a single Session Library to the new Session Driver, two new config items have been added:
+Most notably, - the library now uses separate storage drivers instead of
+always relying on (encrypted) cookies.
+In fact, cookies as storage have now been removed and you must always use
+some kind of server-side storage engine, with the file-system being the
+default option.
 
-   -  ``$config['sess_driver']`` selects which driver to initially load. Options are:
-       -  'cookie' (the default) for classic CodeIgniter cookie-based sessions
-       -  'native' for native PHP Session support
-       -  the name of a custom driver you have provided (see :doc:`Session Driver <../libraries/sessions>` for more info)
-   -  ``$config['sess_valid_drivers']`` provides an array of additional custom drivers to make available for loading
+The Session Class now utilizes PHP's own mechanisms for building custom
+session handlers, which also means that your session data is now
+accessible via the ``$_SESSION`` superglobal (though, we've kept the
+possibility to use it as "userdata", like you've done until now).
 
-As the new Session Driver library loads the classic Cookie driver by default and always makes 'cookie' and 'native'
-available as valid drivers, neither of these configuration items are required. However, it is recommended that you
-add them for clarity and ease of configuration in the future.
+A few configuration options have been removed and a few have been added.
+You should really read the whole :doc:`Session library manual
+</libraries/session>` for the details, but here's a short list of changes
+that you should make:
 
-If you have written a Session extension, you must move it into a 'Session' sub-directory of 'libraries', following the
-standard for Drivers. Also beware that some functions which are not part of the external Session API have moved into
-the drivers, so your extension may have to be broken down into separate library and driver class extensions.
+  - Set your ``$config['sess_driver']`` value
+
+    It will default to 'files', unles you've previously used
+    ``$config['sess_use_database']``, in which case it will be set to
+    'database'.
+
+  - Set a ``$config['sess_save_path']`` value
+
+    For the 'database' driver, a fallback to ``$config['sess_table_name']``
+    is in place, but otherwise requires you to read the manual for the
+    specific driver of your choice.
+
+  - Update your ``ci_sessions`` table ('database' driver only)
+
+    The table structure has changed a bit, and more specifically:
+
+      - ``user_agent`` field is dropped
+      - ``user_data`` field is renamed to ``data`` and under MySQL is now of type BLOB
+      - ``last_activity`` field is renamed to ``timestamp``
+
+    This is accompanied by a slight change in the table indexes too, so
+    please read the manual about the :doc:`Session Database Driver
+    </libraries/session#database-driver>` for more information.
+
+    .. important:: Only MySQL and PostgreSQL are officially supported
+    	now. Other databases may still work, but due to lack of advisory
+    	locking features, they are unsafe for concurrent requests and
+    	you should consider using another driver instead.
+
+  - Remove ``$config['sess_match_useragent']``
+
+    The user-agent string is input supplied by the user's browser, or in
+    other words: client side input. As such, it is an ineffective feature
+    and hence why it has been removed.
+
+  - Remove ``$config['sess_encrypt_cookie']``
+
+    As already noted, the library no longer uses cookies as a storage
+    mechanism, which renders this option useless.
+
+  - Remove ``$config['sess_expire_on_close']``
+
+    This option is still usable, but only for backwards compatibility
+    purposes and it should be otherwise removed. The same effect is
+    achieved by setting ``$config['sess_expiration']`` to 0.
+
+  - Check "flashdata" for collisions with "userdata"
+
+    Flashdata is now just regular "userdata", only marked for deletion on
+    the next request. In other words: you can't have both "userdata" and
+    "flashdata" with the same name, because it's the same thing.
+
+  - Check usage of session metadata
+
+    Previously, you could access the 'session_id', 'ip_address',
+    'user_agent' and 'last_activity' metadata items as userdata.
+    This is no longer possible, and you should read the notes about
+    :doc:`Session Metadata </libraries/session#session-metadata>` if your
+    application relies on those values.
+
+Finally, if you have written a Session extension, you must now move it to
+the *application/libraries/Session/* directory, although chances are that
+it will now also have to be re-factored.
 
 ***************************************
 Step 7: Update your config/database.php
 ***************************************
 
-Due to 3.0.0's renaming of Active Record to Query Builder, inside your `config/database.php`, you will
-need to rename the `$active_record` variable to `$query_builder`

    -  :doc:`Session Library <libraries/sessions>` changes include:
 
-      -  Library changed to :doc:`Driver <general/drivers>` with classic 'cookie' driver as the default.
-      -  Added a 'native' PHP Session driver to work with ``$_SESSION``.
-      -  Added a new **tempdata** feature that allows setting userdata items with expiration time (``tempdata()``, ``set_tempdata()``, ``unset_tempdata()``).
-      -  Added default ``$config['sess_driver']`` and ``$config['sess_valid_drivers']`` items to *application/config.php* file.
-      -  Changed 'cookie' driver to respect php.ini's *session.gc_probability* and *session.gc_divisor* settings.
-      -  Changed 'cookie' driver to use HMAC authentication instead of a simple md5 checksum.
-      -  Changed 'cookie' driver to select only one row when using database sessions.
-      -  Changed 'cookie' driver to write to only write to the database at end of page execution.
+      -  Completely re-written the library to use self-contained drivers via ``$config['sess_driver']``.
+      -  Added 'files', 'database', 'redis' and 'memcached' drivers (using 'files' by default).
+      -  Added ``$config['sess_save_path']`` setting to specify where the session data is stored, depending on the driver.
+      -  Dropped support for storing session data in cookies (which renders ``$config['sess_encrypt_cookie']`` useless and is therefore also removed).
+      -  Dropped official  support for storing session data in databases other than MySQL and PostgreSQL.
+      -  Changed table structure for the 'database' driver.
+      -  Added a new **tempdata** feature that allows setting userdata items with expiration time (``mark_as_temp()``, ``tempdata()``, ``set_tempdata()``, ``unset_tempdata()``).
       -  Changed method ``keep_flashdata()`` to also accept an array of keys.
       -  Changed methods ``userdata()``, ``flashdata()`` to return an array of all userdata/flashdata when no parameter is passed.
       -  Deprecated method ``all_userdata()`` - it is now just an alias for ``userdata()`` with no parameters.
       -  Added method ``has_userdata()`` that verifies the existence of a userdata item.
       -  Added *debug* level log messages for key events in the session validation process.
+      -  Dropped support for the *sess_match_useragent* option.

Subject: [PATCH 3392/5397] Remove error suppression from mysql_*connect()

The suppression was kept so far because mysql_connect(),
mysql_pconnect() emit E_DEPRECATION messages on PHP 5.5+.

Well, we already default to 'mysqli' and there's no reason
to use specifically 'mysql' on PHP 5.5, so we might as well
let the deprecation notices appear and encourage users to
switch drivers.

Subject: [PATCH 3396/5397] Revert 7c4d10660a0a47446474bf97e3cb65f80693f1ee

Deprecates form_prep() in favor of html_escape() (again).

Related: issue #1953, which was the reason for the reverted commit,
but was wrongly interpreted and that shouldn't have happened.

Close #2477

 do other malicious things. The XSS Filter is described
 :doc:`here <../libraries/security>`.
 
-Validate the data
+.. note:: XSS filtering should *only be performed on output*. Filtering
+	input data may modify the data in undesirable ways, including
+	stripping special characters from passwords, which reduces
+	security instead of improving it.
+
+CSRF protection
+===============
+
+CSRF stands for Cross-Site Request Forgery, which is the process of an
+attacker tricking their victim into unknowingly submitting a request.
+
+CodeIgniter provides CSRF protection out of the box, which will get
+automatically triggered for every non-GET HTTP request, but also needs
+you to create your submit forms in a certain way. This is explained in
+the :doc:`Security Library <../libraries/security>` documentation.
+
+Password handling
 =================
 
+It is *critical* that you handle passwords in your application properly.
+
+Unfortunately, many developers don't know how to do that, and the web is
+full of outdated or otherwise wrongful advices, which doesn't help.
+
+We would like to give you a list of combined do's and don'ts to help you
+with that. Please read below.
+
+-  DO NOT store passwords in plain-text format.
+
+   Always **hash** your passwords.
+
+-  DO NOT use Base64 or similar encoding for storing passwords.
+
+   This is as good as storing them in plain-text. Really. Do **hashing**,
+   not *encoding*.
+
+   Encoding, and encryption too, are two-way processes. Passwords are
+   secrets that must only be known to their owner, and thus must work
+   only in one direction. Hashing does that - there's *no* un-hashing or
+   de-hashing, but there is decoding and decryption.
+
+-  DO NOT use weak or broken hashing algorithms like MD5 or SHA1.
+
+   These algorithms are old, proven to be flawed, and not designed for
+   password hashing in the first place.
+
+   Also, DON'T invent your own algorithms.
+
+   Only use strong password hashing algorithms like BCrypt, which is used
+   in PHP's own `Password Hashing <http://php.net/password>`_ functions.
+
+   Please use them, even if you're not running PHP 5.5+, CodeIgniter
+   provides them for you as long as you're running at least PHP version
+   5.3.7 (and if you don't meet that requirement - please, upgrade).
+
+-  DO NOT ever display or send a password in plain-text format!
+
+   Even to the password's owner, if you need a "Forgotten password"
+   feature, just randomly generate a new, one-time (this is also important)
+   password and send that instead.
+
+-  DO NOT put artificial limits on your users' passwords.
+
+   There's no point in forcing a rule that a password can only be up to
+   a number of characters, or that it can't contain a certain set of
+   special characters.
+
+   Not only does this **reduce** security instead of improving it, but
+   there's literally no reason to do it. No technical limitations and
+   no (practical) storage constraints apply once you've hashed them, none!
+
+Validate input data
+===================
+
 CodeIgniter has a :doc:`Form Validation Library
 <../libraries/form_validation>` that assists you in
 validating, filtering, and prepping your data.
 
+Even if that doesn't work for your use case however, be sure to always
+validate and sanitize all input data. For example, if you expect a numeric
+string for an input variable, you can check for that with ``is_numeric()``
+or ``ctype_digit()``. Always try to narrow down your checks to a certain
+pattern.
+
+Have it in mind that this includes not only ``$_POST`` and ``$_GET``
+variables, but also cookies, the user-agent string and basically
+*all data that is not created directly by your own code*.
+
+
 Escape all data before database insertion

       -  Removed method ``is_numeric()`` as it exists as a native PHP function and ``_execute()`` will find and use that (the **is_numeric** rule itself is deprecated since 1.6.1).
       -  Native PHP functions used as rules can now accept an additional parameter, other than the data itself.
       -  Updated method ``set_rules()`` to accept an array of rules as well as a string.
-      -  Added support for ``in`` method that test if a given value is within a given list.
       -  Fields that have empty rules set no longer run through validation (and therefore are not considered erroneous).
       -  Added rule **differs** to check if the value of a field differs from the value of another field.
       -  Added rule **valid_url**.
+      -  Added rule **in_list** to check if the value of a field is within a given list.
       -  Added support for named parameters in error messages.
       -  :doc:`Language <libraries/language>` line keys must now be prefixed with **form_validation_**.
       -  Added rule **alpha_numeric_spaces**.

+A note about concurrency
+------------------------
+
+Unless you're developing a website with heavy AJAX usage, you can skip this
+section. If you are, however, and if you're experiencing performance
+issues, then this note is exactly what you're looking for.
+
+Sessions in previous versions of CodeIgniter didn't implement locking,
+which meant that two HTTP requests using the same session could run exactly
+at the same time. To use a more appropriate technical term - requests were
+non-blocking.
+
+However, non-blocking requests in the context of sessions also means
+unsafe, because modifications to session data (or session ID regeneration)
+in one request can interfere with the execution of a second, concurrent
+request. This detail was at the root of many issues and the main reason why
+CodeIgniter 3.0 has a completely re-written Session library.
+
+Why are we telling you this? Because it is likely that after trying to
+find the reason for your performance issues, you may conclude that locking
+is the issue and therefore look into how to remove the locks ...
+
+DO NOT DO THAT! Removing locks would be **wrong** and it will cause you
+more problems!
+
+Locking is not the issue, it is a solution. Your issue is that you still
+have the session open, while you've already processed it and therefore no
+longer need it. So, what you need is to close the session for the
+current request after you no longer need it.
+
+Long story short - call ``session_write_close()`` once you no longer need
+anything to do with session variables.

Integrating Rufnex's Javascript optional menu replacement :)

Now you will see a small icon in the top right of the user guide browser window. Clicking this toggles between the readdocs style TOC, in the left sidebar, and the "classic" CI TOC, a pulldown activated by clicking on the "Table of Contents" icon at the top of the browser window. The tool use a cookie to remember your decision.

+Routes containing :any
+======================
+
+Historically, CodeIgniter has always provided the **:any** wildcard in
+routing, with the intention of providing a way to match any character
+**within** an URI segment.
+
+However, the **:any** wildcard is actually just an alias for a regular
+expression and used to be executed in that manner as **.+**. This is

+There are certainly many developers that have utilized this bug as an actual

 	(.+)	// matches ANYTHING
 	(:any)	// matches any character, except for '/'
 
+Directories and 'default_controller', '404_override'
+====================================================
+
+As you should know, the ``$route['default_controller']`` and
+``$route['404_override']`` settings accept not only a controller name, but
+also *controller/method* pairs. However, a bug in the routing logic has
+made it possible for some users to use that as *directory/controller*
+instead.
+
+As already said, this behavior was incidental and was never intended, nor
+documented. If you've relied on it, your application will break with
+CodeIgniter 3.0.
+
+Another notable change in version 3 is that 'default_controller' and
+'404_override' are now applied *per directory*. To explain what this means,
+let's take the following example::
+
+	$route['default_controller'] = 'main';
+
+Now, assuming that your website is located at *example.com*, you already
+know that if a user visits ``http://example.com/``, the above setting will
+cause your 'Main' controller to be loaded.
+
+However, what happens if you have an *application/controllers/admin/*
+directory and the user visits ``http://example.com/admin/``?
+In CodeIgniter 3, the router will look for a 'Main' controller under the
+admin/ directory as well. If not found, it will fallback to the parent
+(*application/controllers/*) directory, like in version 2.x.
+
+The same rule applies to the '404_override' setting.
+

URL-decoding isn't compliant with the CGI/1.1 specification.

Subject: [PATCH 3522/5397] Remove 'autoinit' DB setting

It doesn't make sense to do a load->database() call
but not connect to the database. IIRC there was more
stuff in CI_DB_driver::initialize() at some point,
so that was probably the reason why the setting
existed in the first place. However, now it only
results in users making invalid bug reports because
they don't understand the feature ...

Examples during just the past 2 weeks: #3571 #3601 #3607

+   -  Removed **autoinit** configuration setting as it doesn't make sense to instantiate the database class but not connect to the database.
    -  Added subdrivers support (currently only used by PDO).
    -  Added an optional database name parameter to ``db_select()``.
    -  Removed ``protect_identifiers()`` and renamed internal method ``_protect_identifiers()`` to it instead - it was just an alias.

Subject: [PATCH 3556/5397] Fix #3627: Keep timed locks for more than 5 seconds

Emulated locks for Redis and Memcached now have a TTL
of 300 seconds (the default HTTP request timeout value
on many environments) and 30 attemps, each separated by
sleep(1), are made by the blocked request to try and
obtain a lock if it has been freed.

Additionaly, the blocking time for MySQL's locks,
which are also timed, is also set to 300 seconds.

 Encryption Library
 ##################
 
+.. important:: DO NOT use this or any other *encryption* library for
+	user password storage! Passwords must be *hashed* instead, and you
+	should do that via PHP's own `Password Hashing extension
+	<http://php.net/password>`_.
+
 The Encryption Library provides two-way data encryption. To do so in
 a cryptographically secure way, it utilizes PHP extensions that are
 unfortunately not always available on all systems.

 For example, when a call is made to:
 
-	http&#58;//example.com/news/latest/10
+	http://example.com/news/latest/10
 
 We might imagine that there is a controller named "news". The method
 being called on news would be "latest". The news method's job could be to
 grab 10 news items, and render them on the page. Very often in MVC,
 you'll see URL patterns that match:
 
-	http&#58;//example.com/[controller-class]/[controller-method]/[arguments]
+	http://example.com/[controller-class]/[controller-method]/[arguments]
 
 As URL schemes become more complex, this may change. But for now, this
 is all we will need to know.

At current the documentation does not distinguish between DROP TABLE IF EXISTS table_name and DROP TABLE table_name. As seen by the DB_forge.php class in system/database; the function accepts a Boolean as the second parameter as to whether or not to apply the IF EXISTS mysql condition.

Subject: [PATCH 3695/5397] Bug Fix manually delete caching method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

According to documentation, to manually delete cache for page "/foo/bar" we should run $this->output->delete_cache('/foo/bar'), but in this case MD5 hash will be calculated for "http://site.com//foo/bar" and this is why, we should pass $uri without beginning slash (ie, "foo/bar"). But the problem is that there is no way to delete cache for home page because:
1) $this->output->delete_cache('/') — MD5 hash will be calculated for "http://site.com//" and cache file will not be deleted.
2) $this->output->delete_cache('') — MD5 hash will be calculated for "http://site.com/%CURRENT_PAGE%" and again, cache file will not be deleted.

Trimming the beginning slash, we enable ability to delete cache for home page by calling $this->output->delete_cache('/'). Also, this method will work as specified in the documentation.

Subject: [PATCH 3712/5397] Improve Cache Query String behaviour
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Typically, in most cases, we do not need to cache all the Query String variables. That's why I suggest to improve `Cache Include Query String` behaviour — allow the developer to independently specify which variables should be cached.

For example, consider a query to the following URL address:
http://site.com/search?q=query&page=2&session=abcd&utm_source=web

In this case we don't need to build md5 hash for entire query string, because `session` or `utm_source` can be different for all users. The only variables which should be used for md5 hash should be `q` and `page`. Thus, in `config.php` we can use `$config['cache_query_string'] = array('page', 'q');`.

So:
`$config['cache_query_string'] = FALSE;` → Cache Include Query String is disabled
`$config['cache_query_string'] = TRUE;` → Cache Include Query String is enabled for all
`$config['cache_query_string'] = array('page', 'q');` → enabled only for specified variables

Subject: [PATCH 3715/5397] Fixed bug - using field_data() on Oracle databases

When you're using oracle databases and want to retrieve column information through the function field_data($table) you get the following notice:

- Notice: Undefined property: stdClass::$COLUMN_DEFAULT in system/database/drivers/oci8/oci8_driver.php on line 576;

This happens because the oci8 driver tries to access a property that does not exist on query used to get field information. Checking the code we see a small validation to set default value, but the variable $default is not used. So we fix this bug by simply changing:

$retval[$i]->default = $query[$i]->COLUMN_DEFAULT;
to
$retval[$i]->default = $default;

Bug fixed. No more notices and the properly value is set.

Subject: [PATCH 3732/5397] Updated the MySQLi driver to provide support for
 SSL connections as well as additional database connection options. Uses the
 DB_driver class encrypt option as the flag for turning on encryption. Also
 added SSL connection validation with error logging in order to provide users
 a way to know if they are actually connecting via SSL.

Subject: [PATCH 3741/5397] Remove superfluous *Best Practices* parenthetical

In the documentation at user_guide/general/security.html#best-practices, the 3-item list has a superfluous parenthetical that is also misplaced.

This parenthetical currently is at the end of the first list item, though it refers to a step that can replace the first item. As per narfbg's request in PR https://github.com/bcit-ci/CodeIgniter/pull/3915, this change removes the parenthetical entirely.

The change is:

BEFORE:
#. Validate the data to ensure it conforms to the correct type, length,
size, etc. (sometimes this step can replace step one)
#. Filter the data as if it were tainted.
#. Escape the data before submitting it into your database or outputting
it to a browser.

AFTER:
#. Validate the data to ensure it conforms to the correct type, length,
size, etc.
#. Filter the data as if it were tainted.
#. Escape the data before submitting it into your database or outputting
it to a browser.

Subject: [PATCH 3802/5397] Fix an internal bug in QB where() escaping

This is not a supported use case, but if QB escaping is force-disabled,
string values passed to where() or having() aren't escaped. That's wrong
because escape-disabling should only be possible for identifiers and not
values.

Subject: [PATCH 3811/5397] Failed security check

The implemented security check to make sure the path is NOT a URL can easily be bypassed (gives false negative) for all subdomains.
Eg "subdomain.domain.com" should ideally show an error but it does not.

The new security check tries to make a fsockopen connection to validate whether the URL is external or not.

+*********************
+Custom Result Objects
+*********************
+
+You can have the results returned as an instance of a custom class instead of a stdClass or array,
+as the ``result()`` and ``result_array()`` methods allow.This requires that the class is already
+loaded into memory. The class will have all values returned from the database set on the class
+as class variables. If your class already has those class variables created and ``protected`` then
+you should provide a ``__set()`` method to allow the class variables to be set.
+
+Example::
+
+	class User {
+		protected $id;
+		protected $email;
+		protected $username;
+		protected $last_login;
+
+		public function last_login($format)
+		{
+			return date($format, $this->last_login);
+		}
+
+		public function __set($name, $value)
+		{
+			$allowed_vars = array('id', 'email', 'username');
+
+			if (in_array($allowed_vars, $name)
+			{
+				$this->$name = $value;
+			}
+		}
+
+		public function __get($name)
+		{
+			if (isset($this->$name))
+			{
+				return $this->$name;
+			}
+		}
+	}
+
+In addition to the two methods listed below, the following methods also can take a class name
+to return the results as: ``first_row()``, ``last_row()``, ``next_row()``, and ``previous_row()``.
+
+**custom_result_object()**
+
+Returns the entire result set as an array of instances of the class requested. The only parameter
+is the name of the class to instantiate.
+
+Example::
+
+	$query = $this->db->query("YOUR QUERY");
+
+	if ($query->num_rows() > 0)
+	{
+		foreach ($query->custom_result_object('User') as $row)
+		{
+			echo $row->id;
+			echo $row->email;
+			echo $row->last_login('Y-m-d');
+		}
+	}
+
+**custom_row_object()**
+
+Returns a single row from your query results. The first parameter is the row number of the results.
+The second parameter is the class name to instantiate.
+
+Example::
+
+	$query = $this->db->query("YOUR QUERY");
+
+	if ($query->num_rows() > 0)
+	{
+		$row = $query->custom_row_object(0, 'User);
+
+		echo $row->email;   // access attributes
+		echo $row->last_login('Y-m-d');   // access class methods
+	}
+
+You can also use the ``row()`` method in exactly the same way.
+
+Example::
+
+	$row = $query->custom_row_object(0, 'User);

The currently implemented method marks all IPs between 0.0.0.0 - 999.999.999.999 as valid IP Address. Which generates false positives as any IP after 255.255.255.255 is not a valid IP address.

Also, there is no check for IPv6 IP addresses.

filter_var() solves both the issues.

Subject: [PATCH 3885/5397] Fix #4052

The bug actually had two instances:
- Callback routes with literal matches and HTTP verbs has never worked
- The reported issue in #4052, which is a regression introduced in 3.0.1
  with abc299b3a234eb7da1b7e3d257b7eba2da649219

Removed the literal matches logic altogether to avoid similar issues
in the future and reduce code complexity. The same logic is performed
with the regular expressions logic.

 -  Fixed a bug (#4116) - :doc:`Pagination Library <libraries/pagination>` set the wrong page number on the "data-ci-pagination-page" attribute in generated links.
+-  Fixed a bug where :doc:`Pagination Library` added the 'rel="start"' attribute to the first displayed link even if it's not actually linking the first page.

Subject: [PATCH 3941/5397] Refactor 'evil attributes' sanitization logic

Turned out pretty much impossible to do remove 'evil attributes'
with just one pattern - it either breaks something else, hits
pcre.backtrack_limit or causes PHP to segfault.

No benchmarks made, but there shouldn't be any performance
regressions since we're now trying to strip attributes only
after it is determined that they are inside a tag; up until
now this was done seprately for _sanitize_naughty_html()
and _remove_evil_attributes().

Subject: [PATCH 3949/5397] Persist config file settings when resetting
 form_validation

When checking multiple arrays using form_validation you have to call reset_validation between each separate check due to the instance of the library being a singleton.  The issue comes in when the settings are loaded from a config file as they are initially loaded from a parameter in the constructor, but are set to an empty array when resetting the class.  To get around this issue a copy of the config parameter is made and then the copy is used to reset the rules when clearing.

+Step 19: Make sure your 'base_url' config value is not empty
+************************************************************
+
+When ``$config['base_url']`` is not set, CodeIgniter tries to automatically
+detect what your website's base URL is. This is done purely for convenience
+when you are starting development of a new application.
+
+Auto-detection is never reliable and also has security implications, which
+is why you should **always** have it manually configured!
+
+One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,
+and more specifically it now falls back to the server's IP address instead
+of the hostname requested by the client. Therefore, if you've ever relied
+on auto-detection, it will change how your website works now.
+
+In case you need to allow e.g. multiple domains, or both http:// and
+https:// prefixes to be dynamically used depending on the request,
+remember that *application/config/config.php* is still a PHP script, in
+which you can create this logic with a few lines of code. For example::
+
+	$allowed_domains = array('domain1.tld', 'domain2.tld');
+	$default_domain  = 'domain1.tld';
+

+===========================================
+
+"Loading" a database, whether by using the *config/autoload.php* settings
+or manually via calling ``$this->load->database()`` or the less-known
+``DB()`` function, will now throw a ``RuntimeException`` in case of a
+failure.
+
+In addition, being unable to set the configured character set is now also
+considered a connection failure.

+.. note:: This has been the case for most database drivers in the in the
+	past as well (i.e. all but the 'mysql', 'mysqli' and 'postgre'
+	drivers).

+What this means is that if you're unable to connect to a database, or
+have an erroneous character set configured, CodeIgniter will no longer
+fail silently, but will throw an exception instead.
+
+You may choose to explicitly catch it (and for that purpose you can't use
+*config/autoload.php* to load the :doc:`Database Class <../database/index>`)
+::
+
+	try
+	{
+		$this->load->database();
+	}
+	catch (RuntimeException $e)
+	{
+		// Handle the failure
+	}
+
+Or you may leave it to CodeIgniter's default exception handler, which would
+log the error message and display an error screen if you're running in
+development mode.
+
+Remove db_set_charset() calls
+-----------------------------
+
+With the above-mentioned changes, the purpose of the ``db_set_charset()``
+method would now only be to change the connection character set at runtime.
+That doesn't make sense and that's the reason why most database drivers
+don't support it at all.
+Thus, ``db_set_charset()`` is no longer necessary and is removed.

+Step 3: Check usage of doctype() HTML helper
+============================================
+
+The :doc:`HTML Helper <../helpers/html_helper>` function
+:php:func:`doctype()` used to default to 'xhtml1-strict' (XHTML 1.0 Strict)
+when no document type was specified. That default value is now changed to
+'html5', which obviously stands for the modern HTML 5 standard.

+explicitly set the desired format, or adapt your front-end to use proper
+HTML 5 formatting.

Subject: [PATCH 4142/5397] Respect $config['cur_page'] variable for pagination

After upgrading to CI3 I noticed that developers are able to determine the current page counter for pagination based on

* Explicit query string parameters
* URI segment configuration

In earlier versions a developer could still set the current page counter in the pagination lib directly which is useful if you want to use pagination with HTTP POST instead of GET. This could be done by passing

    $config['cur_page']  = '10';

to the pagination function for link generation. Currently this code has changed and will always try to check whether the uri segment is a valid number or not, even if the cur_page variable was passed in the associative array, and fallback to zero if it fails to validate that result.

This can be easily resolved by checking whether the counter was already set with a valid number from the $config array before trying to resolve it from the uri segment.

This fix give a developer more flexibility and stop CI from overwriting the externally set value with an incorrect one.

-Step 3: Check usage of doctype() HTML helper
+Step 3: Check logic related to URI parsing of CLI requests
+==========================================================
+
+When running a CodeIgniter application from the CLI, the
+:doc:`URI Library <libraries/uri>` will now ignore the
+``$config['url_suffix']`` and ``$config['permitted_uri_chars']``
+configuration settings.
+
+These two options don't make sense under the command line (which is why
+this change was made) and therefore you shouldn't be affected by this, but
+if you've relied on them for some reason, you'd probably have to make some
+changes to your code.

+Step 2: Remove 'prep_for_form' usage (deprecation)
+==================================================
+
+The :doc:`Form Validation Library <../libraries/form_validation>` has a
+``prep_for_form()`` method, which is/can also be used as a rule in
+``set_rules()`` to automatically perform HTML encoding on input data.
+
+Automatically encoding input (instead of output) data is a bad practice in
+the first place, and CodeIgniter and PHP itself offer other alternatives
+to this method anyway.
+For example, :doc:`Form Helper <../helpers/form_helper>` functions will
+automatically perform HTML escaping when necessary.
+
+Therefore, the *prep_for_form* method/rule is pretty much useless and is now
+deprecated and scheduled for removal in 3.1+.
+
+.. note:: The method is still available, but you're strongly encouraged to
+	remove its usage sooner rather than later.

-Step 2: Remove 'prep_for_form' usage (deprecation)
+Step 2: Update your index.php file (optional)
+=============================================
+
+We've made some tweaks to the index.php file, mostly related to proper
+usage of directory separators (i.e. use the ``DIRECTORY_SEPARATOR``
+constant instead of a hard coded forward slash "/").

+Nothing will break if you skip this step, but if you're running Windows
+or just want to be up to date with every change - we do recommend that
+you update your index.php file.
+
+*Tip: Just copy the ``ENVIRONMENT``, ``$system_path``, ``$application_folder``
+and ``$view_folder`` declarations from the old file and put them into the
+new one, replacing the defaults.*

+Step 4: Check Cache Library configurations for Redis, Memcache(d)
+=================================================================
+
+The new improvements for the 'redis' and 'memcached' drivers of the
+:doc:`Cache Library <../libraries/caching>` may require some small
+adjustments to your configuration values ...
+
+Redis
+-----
+
+If you're using the 'redis' driver with a UNIX socket connection, you'll
+have to move the socket path from ``$config['socket']`` to
+``$config['host']`` instead.
+
+The ``$config['socket_type']`` option is also removed, although that won't
+affect your application - it will be ignored and the connection type will
+be determined by the format used for ``$config['host']`` instead.
+
+Memcache(d)
+-----------
+
+The 'memcached' will now ignore configurations that don't specify a ``host``
+value (previously, it just set the host to the default '127.0.0.1').
+
+Therefore, if you've added a configuration that only sets e.g. a ``port``,
+you will now have to explicitly set the ``host`` to '127.0.0.1' as well.
+
+Step 5: Check usage of doctype() HTML helper

+Form Validation method prep_for_form()
+======================================
+
+The :doc:`Form Validation Library <../libraries/form_validation>` has a
+``prep_for_form()`` method, which is/can also be used as a rule in
+``set_rules()`` to automatically perform HTML encoding on input data.
+
+Automatically encoding input (instead of output) data is a bad practice in
+the first place, and CodeIgniter and PHP itself offer other alternatives
+to this method anyway.
+For example, :doc:`Form Helper <../helpers/form_helper>` functions will
+automatically perform HTML escaping when necessary.
+
+Therefore, the *prep_for_form* method/rule is pretty much useless and is now
+deprecated and scheduled for removal in 3.1+.
+
+.. note:: The method is still available, but you're strongly encouraged to
+	remove its usage sooner rather than later.

 .. note:: If you have any custom developed files in these directories,

+
+Step 2: Update your "ci_sessions" database table
+================================================
+
+If you're using the :doc:`Session Library </libraries/sessions>` with the
+'database' driver, you may have to ``ALTER`` your sessions table for your
+sessions to continue to work.
+
+.. note:: The table in question is not necessarily named "ci_sessions".
+	It is what you've set as your ``$config['sess_save_path']``.
+
+This will only affect you if you've changed your ``session.hash_function``
+*php.ini* setting to something like 'sha512'. Or if you've been running
+an older CodeIgniter version on PHP 7.1+.
+
+It is recommended that you do this anyway, just to avoid potential issues
+in the future if you do change your configuration.
+
+Just execute the one of the following SQL queries, depending on your
+database::
+
+	// MySQL:
+	ALTER TABLE ci_sessions CHANGE id id varchar(128) NOT NULL;
+
+	// PostgreSQL
+	ALTER TABLE ci_sessions ALTER COLUMN id SET DATA TYPE varchar(128);

+Step 2: Remove usage of nice_date() helper (deprecation)
+========================================================
+
+The :doc:`Date Helper <../helpers/date_helper>` function ``nice_date()`` is
+no longer useful since the introduction of PHP's `DateTime classes
+<https://secure.php.net/datetime>`_
+
+You can replace it with the following:
+::
+
+	DateTime::createFromFormat($input_format, $input_date)->format($desired_output_format);
+
+Thus, ``nice_date()`` is now deprecated and scheduled for removal in
+CodeIgniter 3.2+.
+
+.. note:: The function is still available, but you're strongly encouraged
+	to remove its usage sooner rather than later.

-Email Helper
-############
-
-The Email Helper provides some assistive functions for working with
-Email. For a more robust email solution, see CodeIgniter's :doc:`Email
-Class <../libraries/email>`.
-
-.. important:: The Email helper is DEPRECATED and is currently
-	only kept for backwards compatibility.

-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('email');
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: valid_email($email)
-
-	:param	string	$email: E-mail address
-	:returns:	TRUE if a valid email is supplied, FALSE otherwise
-	:rtype:	bool
-
-	Checks if the input is a correctly formatted e-mail address. Note that is
-	doesn't actually prove that the address will be able recieve mail, but
-	simply that it is a validly formed address.
-
-	Example::
-
-		if (valid_email('email@somesite.com'))
-		{
-			echo 'email is valid';
-		}
-		else
-		{
-			echo 'email is not valid';
-		}
-
-	.. note:: All that this function does is to use PHP's native ``filter_var()``::
-
-		(bool) filter_var($email, FILTER_VALIDATE_EMAIL);
-
-.. php:function:: send_email($recipient, $subject, $message)
-
-	:param	string	$recipient: E-mail address
-	:param	string	$subject: Mail subject
-	:param	string	$message: Message body
-	:returns:	TRUE if the mail was successfully sent, FALSE in case of an error
-	:rtype:	bool
-
-	Sends an email using PHP's native `mail() <http://php.net/function.mail>`_
-	function.
-
-	.. note:: All that this function does is to use PHP's native ``mail``
-
-		::
-
-			mail($recipient, $subject, $message);

-################
-Javascript Class
-################
-
-CodeIgniter provides a library to help you with certain common functions
-that you may want to use with Javascript. Please note that CodeIgniter
-does not require the jQuery library to run, and that any scripting
-library will work equally well. The jQuery library is simply presented
-as a convenience if you choose to use it.
-
-.. important:: This library is DEPRECATED and should not be used. It has always
-	been with an 'experimental' status and is now no longer supported.
-	Currently only kept for backwards compatibility.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-**************************
-Using the Javascript Class
-**************************
-
-Initializing the Class
-======================
-
-To initialize the Javascript class manually in your controller
-constructor, use the ``$this->load->library()`` method. Currently,
-the only available library is jQuery, which will automatically be
-loaded like this::
-
-	$this->load->library('javascript');
-
-The Javascript class also accepts parameters:
-
-- js_library_driver (string) *default: 'jquery'*
-- autoload (bool) *default: TRUE*
-
-You may override the defaults by sending an associative array::
-
-	$this->load->library(
-		'javascript',
-		array(
-			'js_library_driver' => 'scripto',
-			'autoload' => FALSE
-		)
-	);
-
-Again, presently only 'jquery' is available. You may wish to set
-autoload to FALSE, though, if you do not want the jQuery library to
-automatically include a script tag for the main jQuery script file. This
-is useful if you are loading it from a location outside of CodeIgniter,
-or already have the script tag in your markup.
-
-Once loaded, the jQuery library object will be available using:
-
-	$this->javascript
-
-Setup and Configuration
-=======================
-
-Set these variables in your view
---------------------------------
-
-As a Javascript library, your files must be available to your
-application.
-
-As Javascript is a client side language, the library must be able to
-write content into your final output. This generally means a view.
-You'll need to include the following variables in the ``<head>``
-sections of your output.
-
-::
-
-	<?php echo $library_src;?>
-	<?php echo $script_head;?>
-
-
-``$library_src``, is where the actual library file will be loaded, as
-well as any subsequent plugin script calls; $script_head is where
-specific events, functions and other commands will be rendered.
-
-Set the path to the librarys with config items
-----------------------------------------------
-
-There are some configuration items in Javascript library. These can
-either be set in *application/config.php*, within its own
-*config/javascript.php* file, or within any controller usings the
-``set_item()`` function.
-
-An image to be used as an "ajax loader", or progress indicator. Without
-one, the simple text message of "loading" will appear when Ajax calls
-need to be made.
-
-::
-
-	$config['javascript_location'] = 'http://localhost/codeigniter/themes/js/jquery/';
-	$config['javascript_ajax_img'] = 'images/ajax-loader.gif';
-
-If you keep your files in the same directories they were downloaded
-from, then you need not set this configuration items.
-
-The jQuery Class
-================
-
-To initialize the jQuery class manually in your controller constructor,
-use the ``$this->load->library()`` method::
-
-	$this->load->library('javascript/jquery');
-
-You may send an optional parameter to determine whether or not a script
-tag for the main jQuery file will be automatically included when loading
-the library. It will be created by default. To prevent this, load the
-library as follows::
-
-	$this->load->library('javascript/jquery', FALSE);
-
-Once loaded, the jQuery library object will be available using:
-
-	$this->jquery
-
-jQuery Events
-=============
-
-Events are set using the following syntax.
-::
-
-	$this->jquery->event('element_path', code_to_run());
-
-In the above example:
-
--  "event" is any of blur, change, click, dblclick, error, focus, hover,
-   keydown, keyup, load, mousedown, mouseup, mouseover, mouseup, resize,
-   scroll, or unload.
--  "element_path" is any valid `jQuery selector
-   <http://api.jquery.com/category/selectors/>`_. Due to jQuery's unique
-   selector syntax, this is usually an element id, or CSS selector. For
-   example "#notice_area" would effect ``<div id="notice_area">``, and
-   "#content a.notice" would effect all anchors with a class of "notice"
-   in the div with id "content".
--  "``code_to_run()``" is script your write yourself, or an action such as
-   an effect from the jQuery library below.
-
-Effects
-=======
-
-The query library supports a powerful
-`Effects <http://api.jquery.com/category/effects/>`_ repertoire. Before an effect
-can be used, it must be loaded::
-
-	$this->jquery->effect([optional path] plugin name); // for example $this->jquery->effect('bounce');
-
-
-hide() / show()
----------------
-
-Each of this functions will affect the visibility of an item on your
-page. hide() will set an item invisible, show() will reveal it.
-
-::
-
-	$this->jquery->hide(target, optional speed, optional extra information);
-	$this->jquery->show(target, optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-toggle()
---------
-
-toggle() will change the visibility of an item to the opposite of its
-current state, hiding visible elements, and revealing hidden ones.
-
-::
-
-	$this->jquery->toggle(target);
-
-
--  "target" will be any valid jQuery selector or selectors.
-
-animate()
----------
-
-::
-
-	 $this->jquery->animate(target, parameters, optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "parameters" in jQuery would generally include a series of CSS
-   properties that you wish to change.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-For a full summary, see
-`http://api.jquery.com/animate/ <http://api.jquery.com/animate/>`_
-
-Here is an example of an animate() called on a div with an id of "note",
-and triggered by a click using the jQuery library's click() event.
-
-::
-
-	$params = array(
-	'height' => 80,
-	'width' => '50%',
-	'marginLeft' => 125
-	);
-	$this->jquery->click('#trigger', $this->jquery->animate('#note', $params, 'normal'));
-
-fadeIn() / fadeOut()
---------------------
-
-::
-
-	$this->jquery->fadeIn(target,  optional speed, optional extra information);
-	$this->jquery->fadeOut(target,  optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-toggleClass()
--------------
-
-This function will add or remove a CSS class to its target.
-
-::
-
-	$this->jquery->toggleClass(target, class)
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "class" is any CSS classname. Note that this class must be defined
-   and available in a CSS that is already loaded.
-
-fadeIn() / fadeOut()
---------------------
-
-These effects cause an element(s) to disappear or reappear over time.
-
-::
-
-	$this->jquery->fadeIn(target,  optional speed, optional extra information);
-	$this->jquery->fadeOut(target,  optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-slideUp() / slideDown() / slideToggle()
----------------------------------------
-
-These effects cause an element(s) to slide.
-
-::
-
-	$this->jquery->slideUp(target,  optional speed, optional extra information);
-	$this->jquery->slideDown(target,  optional speed, optional extra information);
-	$this->jquery->slideToggle(target,  optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-Plugins
-=======
-
-Some select jQuery plugins are made available using this library.
-
-corner()
---------
-
-Used to add distinct corners to page elements. For full details see
-`http://malsup.com/jquery/corner/ <http://malsup.com/jquery/corner/>`_
-
-::
-
-	$this->jquery->corner(target, corner_style);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "corner_style" is optional, and can be set to any valid style such
-   as round, sharp, bevel, bite, dog, etc. Individual corners can be set
-   by following the style with a space and using "tl" (top left), "tr"
-   (top right), "bl" (bottom left), or "br" (bottom right).
-
-::
-
-	$this->jquery->corner("#note", "cool tl br");

-Smiley Helper
-#############
-
-The Smiley Helper file contains functions that let you manage smileys
-(emoticons).
-
-.. important:: The Smiley helper is DEPRECATED and should not be used.
-	It is currently only kept for backwards compatibility.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('smiley');
-
-Overview
-========
-
-The Smiley helper has a renderer that takes plain text smileys, like
-:-) and turns them into a image representation, like |smile!|
-
-It also lets you display a set of smiley images that when clicked will
-be inserted into a form field. For example, if you have a blog that
-allows user commenting you can show the smileys next to the comment
-form. Your users can click a desired smiley and with the help of some
-JavaScript it will be placed into the form field.
-
-Clickable Smileys Tutorial
-==========================
-
-Here is an example demonstrating how you might create a set of clickable
-smileys next to a form field. This example requires that you first
-download and install the smiley images, then create a controller and the
-View as described.
-
-.. important:: Before you begin, please `download the smiley images
-	<https://ellislab.com/asset/ci_download_files/smileys.zip>`_
-	and put them in a publicly accessible place on your server.
-	This helper also assumes you have the smiley replacement array
-	located at `application/config/smileys.php`
-
-The Controller
---------------
-
-In your **application/controllers/** directory, create a file called
-Smileys.php and place the code below in it.
-
-.. important:: Change the URL in the :php:func:`get_clickable_smileys()`
-	function below so that it points to your smiley folder.
-
-You'll notice that in addition to the smiley helper, we are also using
-the :doc:`Table Class <../libraries/table>`::
-
-	<?php
-
-	class Smileys extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->helper('smiley');
-			$this->load->library('table');
-
-			$image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comments');
-			$col_array = $this->table->make_columns($image_array, 8);
-
-			$data['smiley_table'] = $this->table->generate($col_array);
-			$this->load->view('smiley_view', $data);
-		}
-
-	}
-
-In your **application/views/** directory, create a file called **smiley_view.php**
-and place this code in it::
-
-	<html>
-		<head>
-			<title>Smileys</title>
-			<?php echo smiley_js(); ?>
-		</head>
-		<body>
-			<form name="blog">
-				<textarea name="comments" id="comments" cols="40" rows="4"></textarea>
-			</form>
-			<p>Click to insert a smiley!</p>
-			<?php echo $smiley_table; ?> </body> </html>
-			When you have created the above controller and view, load it by visiting http://www.example.com/index.php/smileys/
-		</body>
-	</html>
-
-Field Aliases
--------------
-
-When making changes to a view it can be inconvenient to have the field
-id in the controller. To work around this, you can give your smiley
-links a generic name that will be tied to a specific id in your view.
-
-::
-
-	$image_array = get_smiley_links("http://example.com/images/smileys/", "comment_textarea_alias");
-
-To map the alias to the field id, pass them both into the
-:func:`smiley_js()` function::
-
-	$image_array = smiley_js("comment_textarea_alias", "comments");
-
-Available Functions
-===================
-
-.. php:function:: get_clickable_smileys($image_url[, $alias = ''[, $smileys = NULL]])
-
-	:param	string	$image_url: URL path to the smileys directory
-	:param	string	$alias: Field alias
-	:returns:	An array of ready to use smileys
-	:rtype:	array
-
-	Returns an array containing your smiley images wrapped in a clickable
-	link. You must supply the URL to your smiley folder and a field id or
-	field alias.
-
-	Example::
-
-		$image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comment');
-
-.. php:function:: smiley_js([$alias = ''[, $field_id = ''[, $inline = TRUE]]])
-
-	:param	string	$alias: Field alias
-	:param	string	$field_id: Field ID
-	:param	bool	$inline: Whether we're inserting an inline smiley
-	:returns:	Smiley-enabling JavaScript code
-	:rtype:	string
-
-	Generates the JavaScript that allows the images to be clicked and
-	inserted into a form field. If you supplied an alias instead of an id
-	when generating your smiley links, you need to pass the alias and
-	corresponding form id into the function. This function is designed to be
-	placed into the <head> area of your web page.
-
-	Example::
-
-		<?php echo smiley_js(); ?>
-
-.. php:function:: parse_smileys([$str = ''[, $image_url = ''[, $smileys = NULL]]])
-
-	:param	string	$str: Text containing smiley codes
-	:param	string	$image_url: URL path to the smileys directory
-	:param	array	$smileys: An array of smileys
-	:returns:	Parsed smileys
-	:rtype:	string
-
-	Takes a string of text as input and replaces any contained plain text
-	smileys into the image equivalent. The first parameter must contain your
-	string, the second must contain the URL to your smiley folder
-
-	Example::
-
-		$str = 'Here are some smileys: :-)  ;-)';
-		$str = parse_smileys($str, 'http://example.com/images/smileys/');
-		echo $str;
-
-.. |smile!| image:: ../images/smile.gif

-###################
-Shopping Cart Class
-###################
-
-The Cart Class permits items to be added to a session that stays active
-while a user is browsing your site. These items can be retrieved and
-displayed in a standard "shopping cart" format, allowing the user to
-update the quantity or remove items from the cart.
-
-.. important:: The Cart library is DEPRECATED and should not be used. 
-	It is currently only kept for backwards compatibility.
-
-Please note that the Cart Class ONLY provides the core "cart"
-functionality. It does not provide shipping, credit card authorization,
-or other processing components.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-********************
-Using the Cart Class
-********************
-
-Initializing the Shopping Cart Class
-====================================
-
-.. important:: The Cart class utilizes CodeIgniter's :doc:`Session
-	Class <sessions>` to save the cart information to a database, so
-	before using the Cart class you must set up a database table as
-	indicated in the :doc:`Session Documentation <sessions>`, and set the
-	session preferences in your application/config/config.php file to
-	utilize a database.
-
-To initialize the Shopping Cart Class in your controller constructor,
-use the ``$this->load->library()`` method::
-
-	$this->load->library('cart');
-
-Once loaded, the Cart object will be available using::
-
-	$this->cart
-
-.. note:: The Cart Class will load and initialize the Session Class
-	automatically, so unless you are using sessions elsewhere in your
-	application, you do not need to load the Session class.
-
-Adding an Item to The Cart
-==========================
-
-To add an item to the shopping cart, simply pass an array with the
-product information to the ``$this->cart->insert()`` method, as shown
-below::
-
-	$data = array(
-		'id'      => 'sku_123ABC',
-		'qty'     => 1,
-		'price'   => 39.95,
-		'name'    => 'T-Shirt',
-		'options' => array('Size' => 'L', 'Color' => 'Red')
-	);
-
-	$this->cart->insert($data);
-
-.. important:: The first four array indexes above (id, qty, price, and
-	name) are **required**. If you omit any of them the data will not be
-	saved to the cart. The fifth index (options) is optional. It is intended
-	to be used in cases where your product has options associated with it.
-	Use an array for options, as shown above.
-
-The five reserved indexes are:
-
--  **id** - Each product in your store must have a unique identifier.
-   Typically this will be an "sku" or other such identifier.
--  **qty** - The quantity being purchased.
--  **price** - The price of the item.
--  **name** - The name of the item.
--  **options** - Any additional attributes that are needed to identify
-   the product. These must be passed via an array.
-
-In addition to the five indexes above, there are two reserved words:
-rowid and subtotal. These are used internally by the Cart class, so
-please do NOT use those words as index names when inserting data into
-the cart.
-
-Your array may contain additional data. Anything you include in your
-array will be stored in the session. However, it is best to standardize
-your data among all your products in order to make displaying the
-information in a table easier.
-
-::
-
-	$data = array(
-		'id'      => 'sku_123ABC',
-		'qty'     => 1,
-		'price'   => 39.95,
-		'name'    => 'T-Shirt',
-		'coupon'	 => 'XMAS-50OFF'
-	);
-
-	$this->cart->insert($data);
-
-The ``insert()`` method will return the $rowid if you successfully insert a
-single item.
-
-Adding Multiple Items to The Cart
-=================================
-
-By using a multi-dimensional array, as shown below, it is possible to
-add multiple products to the cart in one action. This is useful in cases
-where you wish to allow people to select from among several items on the
-same page.
-
-::
-
-	$data = array(
-		array(
-			'id'      => 'sku_123ABC',
-			'qty'     => 1,
-			'price'   => 39.95,
-			'name'    => 'T-Shirt',
-			'options' => array('Size' => 'L', 'Color' => 'Red')
-		),
-		array(
-			'id'      => 'sku_567ZYX',
-			'qty'     => 1,
-			'price'   => 9.95,
-			'name'    => 'Coffee Mug'
-		),
-		array(
-			'id'      => 'sku_965QRS',
-			'qty'     => 1,
-			'price'   => 29.95,
-			'name'    => 'Shot Glass'
-		)
-	);
-
-	$this->cart->insert($data);
-
-Displaying the Cart
-===================
-
-To display the cart you will create a :doc:`view
-file </general/views>` with code similar to the one shown below.
-
-Please note that this example uses the :doc:`form
-helper </helpers/form_helper>`.
-
-::
-
-	<?php echo form_open('path/to/controller/update/method'); ?>
-
-	<table cellpadding="6" cellspacing="1" style="width:100%" border="0">
-
-	<tr>
-		<th>QTY</th>
-		<th>Item Description</th>
-		<th style="text-align:right">Item Price</th>
-		<th style="text-align:right">Sub-Total</th>
-	</tr>
-
-	<?php $i = 1; ?>
-
-	<?php foreach ($this->cart->contents() as $items): ?>
-
-		<?php echo form_hidden($i.'[rowid]', $items['rowid']); ?>
-
-		<tr>
-			<td><?php echo form_input(array('name' => $i.'[qty]', 'value' => $items['qty'], 'maxlength' => '3', 'size' => '5')); ?></td>
-			<td>
-				<?php echo $items['name']; ?>
-
-				<?php if ($this->cart->has_options($items['rowid']) == TRUE): ?>
-
-					<p>
-						<?php foreach ($this->cart->product_options($items['rowid']) as $option_name => $option_value): ?>
-
-							<strong><?php echo $option_name; ?>:</strong> <?php echo $option_value; ?><br />
-
-						<?php endforeach; ?>
-					</p>
-
-				<?php endif; ?>
-
-			</td>
-			<td style="text-align:right"><?php echo $this->cart->format_number($items['price']); ?></td>
-			<td style="text-align:right">$<?php echo $this->cart->format_number($items['subtotal']); ?></td>
-		</tr>
-
-	<?php $i++; ?>
-
-	<?php endforeach; ?>
-
-	<tr>
-		<td colspan="2"> </td>
-		<td class="right"><strong>Total</strong></td>
-		<td class="right">$<?php echo $this->cart->format_number($this->cart->total()); ?></td>
-	</tr>
-
-	</table>
-
-	<p><?php echo form_submit('', 'Update your Cart'); ?></p>
-
-Updating The Cart
-=================
-
-To update the information in your cart, you must pass an array
-containing the Row ID and one or more pre-defined properties to the 
-``$this->cart->update()`` method.
-
-.. note:: If the quantity is set to zero, the item will be removed from
-	the cart.
-
-::
-
-	$data = array(
-		'rowid' => 'b99ccdf16028f015540f341130b6d8ec',
-		'qty'   => 3
-	);
-
-	$this->cart->update($data);
-
-	// Or a multi-dimensional array
-
-	$data = array(
-		array(
-			'rowid'   => 'b99ccdf16028f015540f341130b6d8ec',
-			'qty'     => 3
-		),
-		array(
-			'rowid'   => 'xw82g9q3r495893iajdh473990rikw23',
-			'qty'     => 4
-		),
-		array(
-			'rowid'   => 'fh4kdkkkaoe30njgoe92rkdkkobec333',
-			'qty'     => 2
-		)
-	);
-
-	$this->cart->update($data);
-
-You may also update any property you have previously defined when
-inserting the item such as options, price or other custom fields.
-
-::
-
-	$data = array(
-		'rowid'  => 'b99ccdf16028f015540f341130b6d8ec',
-		'qty'    => 1,
-		'price'	 => 49.95,
-		'coupon' => NULL
-	);
-
-	$this->cart->update($data);
-
-What is a Row ID?
-*****************
-
-The row ID is a unique identifier that is generated by the cart code
-when an item is added to the cart. The reason a unique ID is created
-is so that identical products with different options can be managed
-by the cart.
-
-For example, let's say someone buys two identical t-shirts (same product
-ID), but in different sizes. The product ID (and other attributes) will
-be identical for both sizes because it's the same shirt. The only
-difference will be the size. The cart must therefore have a means of
-identifying this difference so that the two sizes of shirts can be
-managed independently. It does so by creating a unique "row ID" based on
-the product ID and any options associated with it.
-
-In nearly all cases, updating the cart will be something the user does
-via the "view cart" page, so as a developer, it is unlikely that you
-will ever have to concern yourself with the "row ID", other than making
-sure your "view cart" page contains this information in a hidden form
-field, and making sure it gets passed to the ``update()`` method when
-the update form is submitted. Please examine the construction of the
-"view cart" page above for more information.

-		:returns:	TRUE if options exist, FALSE otherwise
-		:rtype:	bool
-
-		Returns TRUE (boolean) if a particular row in the cart contains options.
-		This method is designed to be used in a loop with ``contents()``, since

+Step 8: Make sure you're validating all user inputs
+===================================================
+
+The :doc:`Input Library <../libraries/input>` used to (often
+unconditionally) filter and/or sanitize user input in the ``$_GET``,
+``$_POST`` and ``$_COOKIE`` superglobals.
+
+This was a legacy feature from older times, when things like
+`register_globals <https://secure.php.net/register_globals>`_ and
+`magic_quotes_gpc <https://secure.php.net/magic_quotes_gpc>`_ existed in
+PHP.
+It was a necessity back then, but this is no longer the case and reliance
+on global filters is a bad practice, giving you a false sense of security.
+
+This functionality is now removed, and so if you've relied on it for
+whatever reasons, you should double-check that you are properly validating
+all user inputs in your application (as you always should do).

Subject: [PATCH 4624/5397] Remove needless constructor in model documentation

PHP will execute the parent constructor regardless if a constructor
method is defined in the child class or not. Defining an empty
constructor just to call the parents constructor can be considered bad
practice.

Subject: [PATCH 4625/5397] Add constructor comments to match controller docs

Empty constructors are pointless and bad practice, but removing them
from this part of the documentation makes it less readable, makes less
of a point, and would be quite frankly weird. Added a comment that
suggests that further user code should be put there, like it is in the
controller documentation

Subject: [PATCH 4680/5397] Fixed regex used for loading helpers

We want to exactly match a dot, so we have to escape it.

I found the bug because in my project I load an helper named `session_php_helper.php`, so the `_php` part gets removed and the `session_helper.php` helper gets loaded instead, this way not even an error was shown.

Subject: [PATCH 4703/5397] Fixed show_error() for check $exit_status

At the beginning of the function it checks whether a parameter $status_code is less than 100. Then the parameter $exit_status is formed by summing the $status_code + 9. In this case, the parameter $exit_status can not be more than 108, but somehow it is checked whether the value of the parameter $exit_status over 125. Such a situation can not occur under any circumstances.

+Accessing validated/processed data
+==================================
+
+By default, validation will be performed directly on the ``$_POST`` array,
+and any possible modifications (like trimming whitespace, for example)
+would be written back onto it.  
+However, if you want to keep the original input data intact, or have used
+``set_data()`` to pass a custom set of inputs, you would likely want to
+fetch the now-modified data. In order to do that, you can pass a variable
+as the second parameter to ``run()``::
+
+	$input  = array('name' => '   White Space  ');
+	$output = NULL;
+	
+	$this->form_validation->set_rules('name', 'Name', 'required|trim');
+	$this->form_validation->run(NULL, $output);

+Step 2: Remove usage of the APC Cache driver (deprecation)
+==========================================================
+
+The :doc:`Cache Library <../libraries/caching>` APC driver is now
+deprecated, as the APC extension is effectively dead, as explained in its
+`PHP Manual page <https://secure.php.net/manual/en/intro.apc.php>`_.
+
+If your application happens to be using it, you can switch to another
+cache driver, as APC support will be removed in a future CodeIgniter
+version.

+.. note:: The driver is still available, but you're strongly encouraged
+	to remove its usage sooner rather than later.

Subject: [PATCH 4874/5397] Clean up form validation tests

Remove a number unnecessary calls to reset_validation(). A new
form_validation object is already initialized for every test in
set_up(), so these lines do nothing unless multiple validations
are done in the same test.

Explicitly empty the $_POST array after each test that modifies it.

+=====================================================================

+The :doc:`CAPTCHA Helper <../helpers/captcha_helper>` function
+:php:func:`create_captcha()` allows passing of its ``img_path``, ``img_url``
+and ``font_path`` options as the 2nd, 3rd and 4th parameters respectively.

+	strongly encouraged to remove its usage sooner rather than later.

-Step 3: Change database connection handling
+Step 3: Remove calls to ``CI_Model::__construct()``
+===================================================
+
+The class constructor for ``CI_Model`` never contained vital code or useful
+logic, only a single line to log a message. A change in CodeIgniter 3.1.7
+moved this log message elsewhere and that naturally made the constructor
+completely unnecessary. However, it was left in place to avoid immedate BC
+breaks in a minor release.
+
+In version 3.2.0, that constructor is entirely removed, which would result
+in fatal errors on attempts to call it. Particularly in code like this:
+::
+
+	class Some_model extends CI_Model {
+
+		public function __construct()
+		{
+			parent::__construct(); // calls CI_Model::__construct()
+
+			do_some_other_thing();
+		}
+	}
+
+All you need to do is remove that ``parent::__construct()`` call. On a side
+note, the following seems to be a very common practice:
+::
+
+	class Some_class extends CI_Something {
+
+		public function __construct()
+		{
+			parent::__construct();
+		}
+	}
+
+Please, do NOT do this! It's pointless; it serves no purpose and doesn't do
+anything. If a parent class has a ``__construct()`` method, it will be
+inherited by all its child classes and will execute just fine - you DON'T
+have to explicitly call it unless you want to extend its logic.

Subject: [PATCH 4934/5397] Fix a bug where INTL_IDNA_VARIANT_UTS46 was used
 while undeclared

The constant was introduced in PHP 5.4, and is documented that way, but it actually depends on PHP being linked to ICU 4.6+, while the minimum requirement for compilation is 4.0 ...

When this happens on PHP 7.2, an E_DEPRECATED notice will be emitted; there's currently a discussion on php-internals to resolve that issue.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I didn't understand #5394 that well, what I understood from your comment is that we should convert the charset to UTF-8.
I tested with **マル��イト** but it outputs nothing (empty string), but when I add a character **before** the string (e.g. xマル��イト) it worked fine.

+===========================================

+CodeIgniter uses the [Git-Flow](https://nvie.com/posts/a-successful-git-branching-model/) branching model which requires all pull requests to be sent to the "develop" branch. This is
 where the next planned version will be developed. The "master" branch will always contain the latest stable version and is kept clean so a "hotfix" (e.g: an emergency security patch) can be applied to master to create a new version, without worrying about other features holding it up. For this reason all commits need to be made to "develop" and any sent to "master" will be closed automatically. If you have multiple changes to submit, please place all changes into their own branch on your fork.
 
 One thing at a time: A pull request should only contain one change. That does not mean only one commit, but one change - however many commits it took. The reason for this is that if you change X and Y but send a pull request for both at the same time, we might really want X but disagree with Y, meaning we cannot merge the request. Using the Git-Flow branching model you can create new branches for both of these features and send two requests.

Subject: [PATCH 5004/5397] Use Config::base_url() properly

Using the Config::slash_item() method, we get double forward slashes. For example, base_url = 'http://localhost:8080/' and asset is '/assets/my_asset.css', then the generated URL would be 'http://localhost:8080//assets/my_asset.css'.

This patch fixes that, so the generated URL would be 'http://localhost:8080/assets/my_asset.css'. There is actually already an analog example in the case if index_page === TRUE, where the site_url() function is used.

+Step 13: Check for calls to is_countable()
+==========================================
+
+
+PHP 7.3 introduces a native `is_countable() <https://secure.php.net/is_countable>`_
+function, which creates a name collision with the ``is_countable()`` function
+we've had in our :doc:`Inflector Helpers <../helpers/inflector_helper>`.
+
+If you've been using the helper function in question, you should now rename
+the calls to it to :php:func:`word_is_countable()`.

 - **Security**
 
    -  Updated :doc:`URL Helper <helpers/url_helper>` function :php:func:`auto_link()` to add ``rel="noopener"`` to generated links in order to prevent tab hijacking.
+   -  Fixed a possible session fixation vulnerability where the :doc:`Session Library <libraries/sessions>` enabled ``session.use_strict_mode`` but it didn't actually do anything (thanks to Aamer Shah, Prasanna Kumar).

+Step 2: Check for calls to is_countable()
+==========================================
+
+
+PHP 7.3 introduces a native `is_countable() <https://secure.php.net/is_countable>`_
+function, which creates a name collision with the ``is_countable()`` function
+we've had in our :doc:`Inflector Helpers <../helpers/inflector_helper>`.
+
+If you've been using the helper function in question, you should now rename
+the calls to it to :php:func:`word_is_countable()`.

Subject: [PATCH 5224/5397] Fix database connection leak when closing PDO
 connection

We discovered a resource leak (database connection leak) in our
application's test suite. We investigated and discovered that, although
the test suite was calling `CI_DB_driver::close()` after each test, the
`result_id` member variable still maintained an internal reference to
the database connection, which kept the connection from being closed.

This is using pdo_sqlsrv; I have not tested other PDO drivers.

Subject: [PATCH 5291/5397] Updates .gitattributes, added export-ignore.

Excludes `user_guide_src` via `--prefer-dist` composer installation.

Refer to this https://github.com/bcit-ci/CodeIgniter/issues/5843#issuecomment-889615837 based on this https://github.com/bcit-ci/CodeIgniter/pull/3831

> This basically just removes a number of development-only files (like the user guide source and our tests) from any installs made through composer with the --prefer-dist flag set.
>
> Helps create a faster install with less unnecessary files to new projects.

    -  Removed method ``db_set_charset()`` and the ability to change a connection character set at runtime.

+Step 13: Remove usage of OCI8 get_cursor() and stored_procedure() methods
+=========================================================================
+
+The OCI8 :doc:`Database <database/index>` driver no longer has these two
+methods that were specific to it and not present in other database drivers.
+The ``$curs_id`` property is also removed.
+
+If you were using those, you can create your own cursors via ``oci_new_cursor()``
+and the publicly accessible ``$conn_id()``.

-*************************
-Using the Encrypt Library
-*************************
-
-Setting your Key
-================
-
-A *key* is a piece of information that controls the cryptographic
-process and permits an encrypted string to be decoded. In fact, the key
-you chose will provide the **only** means to decode data that was
-encrypted with that key, so not only must you choose the key carefully,
-you must never change it if you intend use it for persistent data.
-
-It goes without saying that you should guard your key carefully. Should
-someone gain access to your key, the data will be easily decoded. If
-your server is not totally under your control it's impossible to ensure
-key security so you may want to think carefully before using it for
-anything that requires high security, like storing credit card numbers.
-
-To take maximum advantage of the encryption algorithm, your key should
-be 32 characters in length (256 bits). The key should be as random a
-string as you can concoct, with numbers and uppercase and lowercase
-letters. Your key should **not** be a simple text string. In order to be
-cryptographically secure it needs to be as random as possible.
-
-Your key can be either stored in your **application/config/config.php**, or
-you can design your own storage mechanism and pass the key dynamically
-when encoding/decoding.
-
-To save your key to your **application/config/config.php**, open the file
-and set::
-
-	$config['encryption_key'] = "YOUR KEY";
-
-Message Length
-==============
-
-It's important for you to know that the encoded messages the encryption
-function generates will be approximately 2.6 times longer than the
-original message. For example, if you encrypt the string "my super
-secret data", which is 21 characters in length, you'll end up with an
-encoded string that is roughly 55 characters (we say "roughly" because
-the encoded string length increments in 64 bit clusters, so it's not
-exactly linear). Keep this information in mind when selecting your data
-storage mechanism. Cookies, for example, can only hold 4K of
-information.
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Encrypt class is
-initialized in your controller using the ``$this->load->library()``
-method::
-
-	$this->load->library('encrypt');
-
-Once loaded, the Encrypt library object will be available using::
-
-	$this->encrypt
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Encrypt
-
-	.. php:method:: encode($string[, $key = ''])
-
-		:param	string	$string: Data to encrypt
-		:param	string	$key: Encryption key
-		:returns:	Encrypted string
-		:rtype:	string
-
-		Performs the data encryption and returns it as a string. Example::
-
-			$msg = 'My secret message';
-
-			$encrypted_string = $this->encrypt->encode($msg);
-
-		You can optionally pass your encryption key via the second parameter if
-		you don't want to use the one in your config file::
-
-			$msg = 'My secret message';
-			$key = 'super-secret-key';
-
-			$encrypted_string = $this->encrypt->encode($msg, $key);
-
-	.. php:method:: decode($string[, $key = ''])
-
-		:param	string	$string: String to decrypt
-		:param	string	$key: Encryption key
-		:returns:	Plain-text string
-		:rtype:	string
-
-		Decrypts an encoded string. Example::
-
-			$encrypted_string = 'APANtByIGI1BpVXZTJgcsAG8GZl8pdwwa84';
-
-			$plaintext_string = $this->encrypt->decode($encrypted_string);
-
-		You can optionally pass your encryption key via the second parameter if
-		you don't want to use the one in your config file::
-
-			$msg = 'My secret message';
-			$key = 'super-secret-key';
-
-			$encrypted_string = $this->encrypt->decode($msg, $key);
-
-	.. php:method:: set_cipher($cipher)
-
-		:param	int	$cipher: Valid PHP MCrypt cypher constant
-		:returns:	CI_Encrypt instance (method chaining)
-		:rtype:	CI_Encrypt
-
-		Permits you to set an Mcrypt cipher. By default it uses
-		``MCRYPT_RIJNDAEL_256``. Example::
-
-			$this->encrypt->set_cipher(MCRYPT_BLOWFISH);
-
-		Please visit php.net for a list of `available ciphers <https://secure.php.net/mcrypt>`_.
-
-		If you'd like to manually test whether your server supports MCrypt you
-		can use::
-
-			echo extension_loaded('mcrypt') ? 'Yup' : 'Nope';
-
-	.. php:method:: set_mode($mode)
-
-		:param	int	$mode: Valid PHP MCrypt mode constant
-		:returns:	CI_Encrypt instance (method chaining)
-		:rtype:	CI_Encrypt
-
-		Permits you to set an Mcrypt mode. By default it uses **MCRYPT_MODE_CBC**.
-		Example::
-
-			$this->encrypt->set_mode(MCRYPT_MODE_CFB);
-
-		Please visit php.net for a list of `available modes <https://secure.php.net/mcrypt>`_.
-
-	.. php:method:: encode_from_legacy($string[, $legacy_mode = MCRYPT_MODE_ECB[, $key = '']])
-
-		:param	string	$string: String to encrypt
-		:param	int	$legacy_mode: Valid PHP MCrypt cipher constant
-		:param	string	$key: Encryption key
-		:returns:	Newly encrypted string
-		:rtype:	string
-
-		Enables you to re-encode data that was originally encrypted with
-		CodeIgniter 1.x to be compatible with the Encrypt library in
-		CodeIgniter 2.x. It is only necessary to use this method if you have
-		encrypted data stored permanently such as in a file or database and are
-		on a server that supports Mcrypt. "Light" use encryption such as
-		encrypted session data or transitory encrypted flashdata require no
-		intervention on your part. However, existing encrypted Sessions will be
-		destroyed since data encrypted prior to 2.x will not be decoded.
-
-		.. important::
-			**Why only a method to re-encode the data instead of maintaining legacy
-			methods for both encoding and decoding?** The algorithms in the
-			Encrypt library have improved in CodeIgniter 2.x both for performance
-			and security, and we do not wish to encourage continued use of the older
-			methods. You can of course extend the Encryption library if you wish and
-			replace the new methods with the old and retain seamless compatibility
-			with CodeIgniter 1.x encrypted data, but this a decision that a
-			developer should make cautiously and deliberately, if at all.
-
-		::
-
-			$new_data = $this->encrypt->encode_from_legacy($old_encrypted_string);
-

Subject: [PATCH 5380/5397] Adapt unit tests so as not to fail with PHPUnit 8.5

When the phpunit tests are run with phpunit 8.5, they will fail because
the test would call assertMatchesRegularExpression which doesn't exists in
that version.

So check the existence of the method instead of checking the class
'PHPUnit_Runner_Version'.
