+
+
+Contributing
+------------
+
+In order to contribute to pixman, you will need a working knowledge of
+the git version control system. For a quick getting started guide,
+there is the "Everyday Git With 20 Commands Or So guide"
+
+ http://www.kernel.org/pub/software/scm/git/docs/everyday.html
+
+from the Git homepage. For more in depth git documentation, see the
+resources on the Git community documentation page:
+
+ http://git-scm.com/documentation
+
+Pixman uses the infrastructure from the freedesktop.org umbrella
+project. For instructions about how to use the git service on
+freedesktop.org, see:
+
+ http://www.freedesktop.org/wiki/Infrastructure/git/Developers
+
+The Pixman master repository can be found at:
git://anongit.freedesktop.org/git/pixman
- http://gitweb.freedesktop.org/?p=pixman;a=summary
+and browsed on the web here:

+
+
+Sending patches
+---------------
+
+The general workflow for sending patches is to first make sure that
+git can send mail on your system. Then,
+
+ - create a branch off of master in your local git repository
+
+ - make your changes as one or more commits
+
+ - use the
+
+ git send-email
+
+ command to send the patch series to pixman@lists.freedesktop.org.
+
+In order for your patches to be accepted, please consider the
+following guidelines:
+
+ - This link:
+
+ http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#patch-series
+
+ describes how what a good patch series is, and to create one with
+ git.
+
+ - At each point in the series, pixman should compile and the test
+ suite should pass.
+
+ The exception here is if you are changing the test suite to
+ demonstrate a bug. In this case, make one commit that makes the
+ test suite fail due to the bug, and then another commit that fixes
+ the bug.
+
+ You can run the test suite with
+
+ make check
+
+ It will take around two minutes to run on a modern PC.
+
+ - Follow the coding style described in the CODING_STYLE file
+
+ - For bug fixes, include an update to the test suite to make sure
+ the bug doesn't reappear.
+
+ - For new features, add tests of the feature to the test
+ suite. Also, add a program demonstrating the new feature to the
+ demos/ directory.
+
+ - Write descriptive commit messages. Useful information to include:
+ - Benchmark results, before and after
+ - Description of the bug that was fixed
+ - Detailed rationale for any new API
+ - Alternative approaches that were rejected (and why they
+ don't work)
+ - If review comments were incorporated, a brief version
+ history describing what those changes were.
+
+ - For big patch series, send an introductory email with an overall
+ description of the patch series, including benchmarks and
+ motivation. Each commit message should still be descriptive and
+ include enough information to understand why this particular commit
+ was necessary.
-For more information on the git code manager, see:
+Pixman has high standards for code quality and so almost everybody
+should expect to have the first versions of their patches rejected.
- http://wiki.x.org/wiki/GitPage
+If you think that the reviewers are wrong about something, or that the
+guidelines above are wrong, feel free to discuss the issue on the
+list. The purpose of the guidelines and code review is to ensure high
+code quality; it is not an exercise in compliance.
