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.

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.
