+# 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:
+
+1. There is not already an open Issue
+2. The issue has already been fixed (check the develop branch, or look for closed Issues)
+3. 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`
+

+## 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".
+
+1. Set up Git (Windows, Mac & Linux)
+2. Go to the CodeIgniter repo
+3. Fork it
+4. Clone your CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git
+5. Checkout the "develop" branch At this point you are ready to start making changes.
+6. Fix existing bugs on the Issue tracker after taking a look to see nobody else is working on them.
+7. Commit the files
+8. Push your develop branch to your fork
+9. Send a pull request [http://help.github.com/send-pull-requests/](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:
+
+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.

Please see the `installation section <http://codeigniter.com/user_guide/installation/index.html>`_
of the CodeIgniter User Guide.
-************
-Contributing
-************
-
-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.

+/**
+ * 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.

Use of the ``$autoload['core']`` config array has been deprecated as of CodeIgniter 1.4.1 and is now removed.

+**************************************************************
+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.

Migrations Class
################
-Coming soon.
\ No newline at end of file
+Migrations are a convenient way for you to alter your database in a
+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.

+In addition to the values above, the cookie and native drivers apply the

+
+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
+(sess_regenerate), 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
