Release management

All released versions are listed at the Release notes page. Tarantool Release Policy explains the rules and meaning of numbers in x.y.z versions.

This page will tell you how to make a Tarantool release.

$ git tag -a 2.4 -m "Next minor in 2.x series"
$ vim CMakeLists.txt # edit CPACK_PACKAGE_VERSION_PATCH
$ git push --tags

A tag which is made on a git branch can be taken along with a merge, or left on the branch. The technique to “keep the tag on the branch it was originally set on” is to use --no-fast-forward when merging this branch.

With --no-ff, a merge changeset is created to represent the received changes, and only that merge changeset ends up in the destination branch. This technique can be useful when there are two active lines of development, e.g. “stable” and “next”, and it’s necessary to be able to tag both lines independently.

To make sure that a tag doesn’t end up in the destination branch, it is necessary to have the commit to which the tag is attached, “stay on the original branch”. That’s exactly what a merge with disabled “fast-forward” does – creates a “merge” commit and adds it to both branches.

Here’s what it may look like:

kostja@shmita:~/work/tarantool$ git checkout master
Already on 'master'
kostja@shmita:~/work/tarantool$ git tag -a 2.4 -m "Next development"
kostja@shmita:~/work/tarantool$ git describe
2.4
kostja@shmita:~/work/tarantool$ git checkout master-stable
Switched to branch 'master-stable'
kostja@shmita:~/work/tarantool$ git tag -a 2.3 -m "Next stable"
kostja@shmita:~/work/tarantool$ git describe
2.3
kostja@shmita:~/work/tarantool$ git checkout master
Switched to branch 'master'
kostja@shmita:~/work/tarantool$ git describe
2.4
kostja@shmita:~/work/tarantool$ git merge --no-ff master-stable

Also, don’t forget this:

  1. Update all issues. Upload the ChangeLog based on git log output.

    The ChangeLog must only include items which are mentioned as issues on GitHub. If anything significant is there, which is not mentioned, something went wrong in release planning and the release should be held up until this is cleared.

  2. Click ‘Release milestone’. Create a milestone for the next minor release. Alert the driver to target bugs and blueprints to the new milestone.
