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
|
|
|

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.
|
|
|
|
Pixman has high standards for code quality and so almost everybody
|
|
should expect to have the first versions of their patches rejected.
|
|
|
|
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.
