When base_url is a URL based on protocol, like "//www.google.com" the double slash regex kills the first "//".

Subject: [PATCH 0002/1683] 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 0003/1683] 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 0018/1683] 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 0027/1683] 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 0088/1683] Fix an internal bug in QB where() escaping

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.

+-  Fixed a bug (#3279) - :doc:`Query Builder <database/query_builder>` methods ``update()`` and ``get_compiled_update()`` did double escaping on the table name if it was provided via ``from()``.

Subject: [PATCH 0097/1683] 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);

Subject: [PATCH 0115/1683] IP checking false positives and no ipv6 check

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 0171/1683] 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.

Subject: [PATCH 0227/1683] 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 0235/1683] 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 0428/1683] 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 0910/1683] 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 0911/1683] 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 0966/1683] 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 0989/1683] 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 1160/1683] 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 1220/1683] 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 **マルチバイト** but it outputs nothing (empty string), but when I add a character **before** the string (e.g. xマルチバイト) 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 1290/1683] 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 1510/1683] 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.

Date: Fri, 30 Jul 2021 11:44:21 +0700
Subject: [PATCH 1577/1683] 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 1666/1683] 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'.
