Bugfix branches
|
||||
===============
|
||||
|
||||
The following projects have ``bugfix/X.Y`` branches in addition to standard
|
||||
openstack ``stable/NAME`` branches:
|
||||
|
||||
* bifrost
|
||||
* ironic
|
||||
* ironic-inspector
|
||||
* ironic-python-agent
|
||||
|
||||
They are also released on a regular cadence as opposed to on-demand, namely
|
||||
three times a release cycle (roughly a release every 2 months). One of the
|
||||
releases corresponds to the coordinated OpenStack released and receives a
|
||||
``stable/NAME`` branch. The other two happen during the cycle and receive a
|
||||
``bugfix/X.Y`` branch, where ``X.Y`` consists of the major and the minor
|
||||
component of the version (e.g. ``bugfix/8.1`` for 8.1.0).
|
||||
|
||||
To leave some version space for releases from these branches, releases of these
|
||||
projects from the master branch always increase either the major or the minor
|
||||
version.
|
||||
|
||||
Currently releases from bugfix branches cannot be automated and must be done by
|
||||
the release team manually.
|
||||
|
||||
Things to do before releasing
|

=============================

@ -306,6 +331,25 @@ We need to submit patches for changes on master to:
|
||||
|
||||
* remove any model class names from ``ironic.cmd.dbsync.NEW_MODELS``.
|
||||
|
||||
When a release is done that results in a bugfix branch
|
||||
------------------------------------------------------
|
||||
|
||||
In this case the release management only creates a change to point
|
||||
``.gitreview`` at the branch, ``tox.ini`` is not modified.
|
||||
|
||||
After the release:
|
||||
|
||||
* update the Tempest microversions as explained above.
|
||||
|
||||
* the CI needs additional configuration, so that Zuul knows which branch to
|
||||
take jobs definitions from. See the following examples:
|
||||
|
||||
* `ironic 18.1 <https://review.opendev.org/c/openstack/ironic/+/801876>`_
|
||||
* `ironic-inspector 10.7
|
||||
<https://review.opendev.org/c/openstack/ironic-inspector/+/801873>`_
|
||||
* `ironic-python-agent 8.1
