|
== Applied local patches ==
|
|
|
|
In this order:
|
|
|
|
angle-renaming-debug.patch
|
|
rename debug.h to compilerdebug.h to avoid conflict in our makefiles
|
|
|
|
angle-renaming-preprocessor-diagonostics.patch
|
|
rename one of the two Diagnostics.cpp to avoid conflict in our makefiles
|
|
|
|
angle-renaming-preprocessor-directivehandler.patch
|
|
rename one of the two DirectiveHandler.cpp to avoid conflict in our makefiles
|
|
|
|
angle-enforce-readpixels-spec.patch
|
|
see bug 724476
|
|
|
|
angle-impl-read-bgra.patch
|
|
see bug 724476
|
|
|
|
gfx/angle/angle-long-identifier-hash-spooky.patch
|
|
see bug 676071
|
|
|
|
angle-abort-on-oom-in-preprocessor.patch
|
|
see bug 680840. Probably not useful anymore now that we're on the new
|
|
preprocessor, but it doesn't hurt to keep it around a bit longer.
|
|
|
|
angle-faceforward-emu.patch
|
|
See bug 771406. Adds emulation for faceforward(float,float,float),
|
|
which is needed to prevent crashing on Mac+Intel.
|
|
|
|
angle-r1278.patch
|
|
Imports ANGLE r1278, which fixes ANGLE bug 350, a crasher.
|
|
|
|
In addition to these patches, the Makefile.in files are ours, they're not present in
|
|
upsteam ANGLE. Therefore, changes made to the Makefile.in files should not be stored
|
|
in the local .patch files.
|
|
|
|
== How to update this ANGLE copy ==
|
|
|
|
1. Unapply patches
|
|
|
|
Unapply them in reverse order, so iterate over the above list of applied patch
|
|
starting from the bottom. You most likely want to record these patch-unapply
|
|
operations as individual patches themselves, in order to re-apply patches later.
|
|
|
|
$ cd /path/to/mozilla-central
|
|
|
|
$ patch -p1 -R < gfx/angle/angle-some-bug-fix.patch
|
|
$ hg qnew unapply-angle-some-bug-fix.patch
|
|
|
|
2. Apply diff with new ANGLE version
|
|
|
|
Check at the top of this file what ANGLE revision we currently have. Let's say it's
|
|
r123. Check at the ANGLE Web site what recent revisions look like to figure what
|
|
revision seems safe. Let's say we want r456.
|
|
|
|
$ cd
|
|
$ svn checkout http://angleproject.googlecode.com/svn/trunk/ angleproject
|
|
$ cd angleproject
|
|
$ svn diff -r 123:456 > ~/angle-diff-from-123-to-456
|
|
$ cd /path/to/mozilla-central
|
|
$ cd gfx/angle
|
|
$ patch -p0 < ~/angle-diff-from-123-to-456
|
|
$ cd ../..
|
|
$ hg status
|
|
# hg add any new ANGLE files under gfx/angle
|
|
$ hg qnew angle-diff-from-123-to-456
|
|
|
|
3. Reapply patches
|
|
|
|
You may have to skip reapplying certain patches there, for example if they have
|
|
been integrated into ANGLE since our last update. The short patch descriptions above
|
|
in this file should help you make that decision.
|
|
|
|
If you have recorded the individual patch unapply operations in step 1 as separate
|
|
Mercurial patches, this will be easy, just apply the inverse patches now, in reverse
|
|
order:
|
|
|
|
$ patch -p1 -R < .hg/patches/unapply-angle-some-bug-fix.patch
|
|
$ hg status
|
|
# hg add any new ANGLE files under gfx/angle
|
|
$ hg qnew angle-some-bug-fix.patch
|
|
|
|
Note that here you need to proceed in the reverse order of what you did in step 1.
|
|
|
|
4. Update our Makefiles
|
|
|
|
Open your ANGLE diff file (~/angle-diff-from-123-to-456), search for GYP files
|
|
(e.g. build_angle.gyp), it's easy-to-read JSON. It may list additions of new files,
|
|
or removal of old files. You have to reflect this in our Makefiles:
|
|
|
|
gfx/angle/Makefile.in
|
|
gfx/angle/src/libEGL/Makefile.in
|
|
gfx/angle/src/libGLESv2/Makefile.in
|
|
|
|
The first one is our main Makefile. It has basically the ANGLE shader compiler.
|
|
Changes there will typically have to be applied also to the two other Makefiles.
|
|
These two other Makefiles are Windows-only and build the ANGLE GLES2-on-top-of-D3D
|
|
implementation.
|
|
|
|
5. Update patch files
|
|
|
|
Something like:
|
|
|
|
$ cp .hg/patches/angle-some-bug-fix.patch gfx/angle
|
|
|
|
For each patch that you reapplied.
|
|
|
|
If a patch was removed (not reapplied), remove the corresponding patch file.
|
|
|
|
6. Update this README.mozilla
|
|
|
|
You'll have to update at least the ANGLE revision number and probably the patch
|
|
list as well.
|
|
|
|
7. Push to Try
|
|
|
|
Make sure to test both Windows and non-Windows, and enable mochitest-1 in your
|
|
Try options. You may want reftest as well, as we have WebGL reftests.
|
|
|
|
8. Get reviews.
|
|
|
|
Typically, you would get review on your Makefiles patch, and any
|
|
new patches that you need to add to get this update to work.
|
|
|
|
You do not need a review for the ANGLE diff itself and for trivial updates of
|
|
existing patches.
|
|
|
|
== Visual Studio Solution Files ==
|
|
|
|
Ignore these. We don't use them anymore. We use custom Makefiles.
|
|
|
|
== Generated parser code==
|
|
|
|
Don't bother about that anymore. The parser is now generated and included in the ANGLE svn repo.
