Criteria for accepting patches to the stable branch

-Please use git cherry-pick -x <commit> for cherry-picking a commit -from master to a stable branch. -

+Mesa has a designated release manager for each stable branch, and the release +manager is the only developer that should be pushing changes to these +branches. Everyone else should simply nominate patches using the mechanism +described above. + +The stable-release manager will work with the list of nominated patches, and +for each patch that meets the crtieria below will cherry-pick the patch with: +git cherry-pick -x <commit>. The -x option is +important so that the picked patch references the comit ID of the original +patch. + +The stable-release manager may at times need to force-push changes to the +stable branches, for example, to drop a previously-picked patch that was later +identified as causing a regression). These force-pushes may cause changes to +be lost from the stable branch if developers push things directly. Consider +yourself warned. + +The stable-release manager is also given broad discretion in rejecting patches +that have been nominated for the stable branch. The most basic rule is that +the stable branch is for bug fixes only, (no new features, no +regressions). Here is a non-exhaustive list of some reasons that a patch may +be rejected: + +

Making a New Mesa Release

Get latest source files

Use git to get the latest Mesa files from the git repository, from whatever -branch is relevant. +branch is relevant. This document uses the convention X.Y.Z for the release +being created, which should be created from a branch named X.Y. +

+ +

Perform basic testing

+

+The release manager should, at the very least, test the code by compiling it, +installing it, and running the latest piglit to ensure that no piglit tests +have regressed since the previous release. +

+ +

+The release manager should do this testing with at least one hardware driver, +(say, whatever is contained in the local development machine), as well as on +both Gallium and non-Gallium software drivers. The software testing can be +performed by running piglit with the following environment-variable set: +

+ +
+LIBGL_ALWAYS_SOFTWARE=1
+
+ +And Gallium vs. non-Gallium software drivers can be obtained by using the +following configure flags on separate builds: + +
+--with-dri-drivers=swrast
+--with-gallium-drivers=swrast
+
+ +

+Note: If both options are given in one build, both swrast_dri.so drivers will +be compiled, but only one will be installed. The following command can be used +to ensure the correct driver is being tested:

+
+LIBGL_ALWAYS_SOFTWARE=1 glxinfo | grep "renderer string"
+
+ +If any regressions are found in this testing with piglit, stop here, and do +not perform a release until regressions are fixed. -

Verify and update version info in VERSION

+

Update version in file VERSION

-Create a docs/relnotes/x.y.z.html file. -The bin/bugzilla_mesa.sh and bin/shortlog_mesa.sh scripts can be used to -create the HTML-formatted lists of bugfixes and changes to include in the file. -Link the new docs/relnotes/x.y.z.html file into the main relnotes.html file. +Increment the version contained in the file VERSION at Mesa's top-level, then +commit this change.

+

Create release notes for the new release

+

-Update docs/index.html. +Create a new file docs/relnotes/X.Y.Z.html, (follow the style of the previous +release notes). Note that the sha256sums section of the release notes should +be empty at this point.

-Tag the files with the release name (in the form mesa-x.y) -with: git tag -s mesa-x.y -m "Mesa x.y Release" -Then: git push origin mesa-x.y +Two scripts are available to help generate portions of the release notes: + +

+	./bin/bugzilla_mesa.sh
+	./bin/shortlog_mesa.sh
+
+ +

+The first script identifies commits that reference bugzilla bugs and obtains +the descriptions of those bugs from bugzilla. The second script generates a +log of all commits. In both cases, HTML-formatted lists are printed to stdout +to be included in the release notes.

Make the tarballs

Make the release archives, signatures, and the release tag

 	./autogen.sh
-	make tarballs
+	make -j1 tarballs

-After the tarballs are created, the md5 checksums for the files will -be computed. -Add them to the docs/relnotes/x.y.html file. +After the tarballs are created, the sha256 checksums for the files will +be computed and printed. These will be used in a step below.

-Copy the distribution files to a temporary directory, unpack them, -compile everything, and run some demos to be sure everything works. +It's important at this point to also verify that the constructed tar file +actually builds:

-

Update the website and announce the release

+
+	tar xjf MesaLib-X.Y.Z.tar.bz2
+	cd Mesa-X.Y.Z
+	./configure --enable-gallium-llvm
+	make -j6
+	make install
+
+

-Make a new directory for the release on annarchy.freedesktop.org with: -
- -mkdir /srv/ftp.freedesktop.org/pub/mesa/x.y - +Some touch testing should also be performed at this point, (run glxgears or +more involved OpenGL programs against the installed Mesa).

-Basically, to upload the tarball files with: -
- -rsync -avP -e ssh MesaLib-x.y.* USERNAME@annarchy.freedesktop.org:/srv/ftp.freedesktop.org/pub/mesa/x.y/ - +Create detached GPG signatures for each of the archive files created above: +

+ +
+	gpg --sign --detach MesaLib-X.Y.Z.tar.gz
+	gpg --sign --detach MesaLib-X.Y.Z.tar.bz2
+	gpg --sign --detach MesaLib-X.Y.Z.zip
+
+ +

+Tag the commit used for the build: +

+ +
+	git tag -s mesa-X.Y.X -m "Mesa X.Y.Z release"
+
+ +

+Note: It would be nice to investigate and fix the issue that causes the +tarballs target to fail with multiple build process, such as with "-j4". It +would also be nice to incorporate all of the above commands into a single +makefile target. And instead of a custom "tarballs" target, we should +incorporate things into the standard "make dist" and "make distcheck" targets. +

+ +

Add the sha256sums to the release notes

+ +

+Edit docs/relnotes/X.Y.Z.html to add the sha256sums printed as part of "make +tarballs" in the previous step. Commit this change. +

+ +

Push all commits and the tag creates above

+ +

+This is the first step that cannot easily be undone. The release is going +forward from this point: +

+ +
+	git push origin X.Y --tags
+
+ +

Install the release files and signatures on the distribution server

+ +

+The following commands can be used to copy the release archive files and +signatures to the freedesktop.org server: +

+ +
+	scp MesaLib-X.Y.Z* people.freedesktop.org:
+	ssh people.freedesktop.org
+	cd /srv/ftp.freedesktop.org/pub/mesa
+	mkdir X.Y.Z
+	cd X.Y.Z
+	mv ~/MesaLib-X.Y.Z* .
+
+ +

Back on mesa master, andd the new release notes into the tree

+ +

+Something like the following steps will do the trick: +

+ +
+	cp docs/relnotes/X.Y.Z.html /tmp
+        git checkout master
+        cp /tmp/X.Y.Z.html docs/relnotes
+        git add docs/relnotes/X.Y.Z.html
+
+ +

+Also, edit docs/relnotes.html to add a link to the new release notes, and edit +docs/index.html to add a news entry. Then commit and push: +

+ +
+	git commit -a -m "docs: Import X.Y.Z release notes, add news item."
+        git push origin
+
+ +

Update the mesa3d.org website

+ +

+NOTE: The recent release managers have not been performing this step +themselves, but leaving this to Brian Paul, (who has access to the +sourceforge.net hosting for mesa3d.org). Brian is more than willing to grant +the permission necessary to future release managers to do this step on their +own.
