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.
