To make a release of Weston and/or Wayland, follow these steps.
0. Verify the test suites and codebase checks pass. All of the
tests pass should either pass or skip.
$ make check
1. For Weston, verify that the wayland and wayland-protocols version
dependencies are correct, and that wayland-protocols has had a
release with any needed protocol updates.
2. Update the first stanza of configure.ac to the intended versions
for weston and libweston.
For Weston's x.y.0 releases, if libweston_major_version is greater than
weston_major_version, bump the Weston version numbers (major, minor,
micro) to match the libweston version numbers (major, minor, patch).
Additionally for all Weston releases, if libweston version
major.minor.patch is less than Weston version major.minor.micro, bump
libweston version numbers to match the Weston version numbers.
Weston releases are made with the Weston version number, not with the
libweston version number.
Then commit your changes:
$ export RELEASE_NUMBER="x.y.z"
$ export RELEASE_NAME="[alpha|beta|RC1|RC2|official|point]"
$ git status
$ git commit configure.ac -m "configure.ac: bump to version $RELEASE_NUMBER for the $RELEASE_NAME release"
$ git push
3. For Weston releases, install Xwayland, either from your distro or
manually (see http://wayland.freedesktop.org/building.html). If
you install it to a location other than /usr/bin/Xwayland, specify
this in the following env var:
XWAYLAND=$(which Xwayland) # Or specify your own path
export DISTCHECK_CONFIGURE_FLAGS="--with-xserver-path=$XWAYLAND"
If you're using a locally installed libinput or other dependency
libraries, you'll likely need to set a few other environment
variables:
export WLD="<path-to-your-local-installation>"
export LD_LIBRARY_PATH=$WLD/lib
export PKG_CONFIG_PATH=$WLD/lib/pkgconfig:$WLD/share/pkgconfig/
4. Run the release.sh script to generate the tarballs, sign and
upload them, and generate a release announcement template.
This script can be obtained from X.org's modular package:
http://cgit.freedesktop.org/xorg/util/modular/tree/release.sh
The script supports a --dry-run option to test it without actually
doing a release. If the script fails on the distcheck step due to
a testsuite error that can't be fixed for some reason, you can
skip testsuite by specifying the --dist argument. Pass --help to
see other supported options.
$ release.sh .
For wayland, also publish the publican documentation to
wayland.freedesktop.org:
$ ./publish-doc
5. Compose the release announcements. The script will generate
*.x.y.z.announce files with a list of changes and tags, one for
wayland, one for weston. Prepend these with a human-readable
listing of the most notable changes. For x.y.0 releases, indicate
the schedule for the x.y+1.0 release.
6. pgp sign the the release announcements and send them to
wayland-devel@lists.freedesktop.org
7. Update releases.html in wayland-web with links to tarballs and
the release email URL.
The wl_register_release script in wayland-web will generate an HTML
snippet that can be pasted into releases.html (or e.g. in emacs
insert it via "C-u M-! scripts/wl_register_release x.y.z") and
customized.
Once satisfied:
$ git commit ./releases.html -m "releases: Add ${RELEASE_NUMBER} release"
$ git push
$ ./deploy
8. Update topic in #wayland to point to the release announcement URL
For x.y.0 releases, also create the release series x.y branch. The x.y
branch is for bug fixes and conservative changes to the x.y.0 release,
and is where we create x.y.z releases from. Creating the x.y branch
opens up master for new development and lets new development move on.
We've done this both after the x.y.0 release (to focus development on
bug fixing for the x.y.1 release for a little longer) or before the
x.y.0 release (like we did with the 1.5.0 release, to unblock master
development early).
$ git branch x.y [sha]
$ git push origin x.y
The master branch configure.ac version should always be (at least)
x.y.90, with x.y being the most recent stable branch. Stable branch
configure version is just whatever was most recently released from
that branch.
For stable branches, we commit fixes to master first, then cherry-pick
them back to the stable branch.
