Quick Guide To Patching This Package For The Impatient
------------------------------------------------------
1. Make sure you have quilt installed
2. Unpack the package as usual with "dpkg-source -x"
3. Run the "patch" target in debian/rules
4. Create a new patch with "quilt new" (see quilt(1))
5. Edit all the files you want to include in the patch with "quilt edit"
(see quilt(1)).
6. Write the patch with "quilt refresh" (see quilt(1))
7. Run the "clean" target in debian/rules
Alternatively, instead of using quilt directly, you can drop the patch in to
debian/patches and add the name of the patch to debian/patches/series.
The X Strike Force team maintains X packages in git repositories on
git.debian.org in the pkg-xorg subdirectory. Most upstream packages
are actually maintained in git repositories as well, so they often
just need to be pulled into git.debian.org in a "upstream-*" branch.
The .orig.tar.gz upstream source file could be generated this
"upstream-*" branch in the Debian git repository but it is actually
generated from upstream tarballs directly.
Upstream ships Mesa as 3 different tarballs (MesaLib, MesaGLUT and
MesaDemos) which are re-bundled together into a single .orig.tar.gz.
The Debian packaging is added by creating the "debian-*" git branch
which contains the aforementioned "upstream-*" branch plus the debian/
repository files.
When a patch has to be applied to the Debian package, two solutions
are involved:
* If the patch is available in one of the upstream branches, it
may be git'cherry-picked into the Debian repository. In this
case, it appears directly in the .diff.gz.
* Otherwise, the patch is added to debian/patches/ which is managed
with quilt as documented in /usr/share/doc/quilt/README.source.
Thus, the patching system requires a build dependency on quilt.
