These steps describe releasing the libmongocrypt C library (not the language bindings).
Version numbers of libmongocrypt must follow the format 1.[0-9].[0-9] for releases and 1.[0-9].[0-9]-(alpha|beta|rc)[0-9] for pre-releases. This ensures that Linux distribution packages built from each commit are published to the correct location.
Do the following when releasing:
-
Ensure
etc/purls.txt
is up-to-date. -
If this is a feature release (e.g.
x.y.0
orx.0.0
), follow these steps: Creating SSDLC static analysis reports. -
Update CHANGELOG.md with the version being released.
-
Check out the release branch. For a release
x.y.z
, the release branch isrx.y
. If this is a new minor release (x.y.0
), create the release branch. -
If this is a new minor release (e.g.
x.y.0
):- Update the Linux distribution package installation instructions in the below sections to refer to the new version
x.y
. - Update the libmongocrypt-release Evergreen project (requires auth) to set
Branch Name
torx.y
.
- Update the Linux distribution package installation instructions in the below sections to refer to the new version
-
Commit the changes on the
rx.y
branch with a message like "Update CHANGELOG.md for x.y.z". -
Tag the commit with
git tag -a <tag>
.- Push both the branch ref and tag ref in the same command:
git push origin master 1.8.0-alpha0
orgit push origin r1.8 1.8.4
- Pushing the branch ref and the tag ref in the same command eliminates the possibility of a race condition in Evergreen (for building resources based on the presence of a release tag)
- Note that in the future (e.g., if we move to a PR-based workflow for releases, or if we simply want to take better advantage of advanced Evergreen features), it is possible to use Evergreen's "Trigger Versions With Git Tags" feature by updating both
config.yml
and the project's settings in Evergreen
- Push both the branch ref and tag ref in the same command:
-
Ensure the version on Evergreen with the tagged commit is scheduled. The following tasks must pass to complete the release:
upload-all
windows-upload-release
- All
publish-packages
tasks.- If the
publish-packages
tasks fail with an error like[curator] 2024/01/02 13:56:17 [p=emergency]: problem submitting repobuilder job: 404 (Not Found)
, this suggests the published path does not yet exist. Barque (the Linux package publishing service) has protection to avoid unintentional publishes. File a DEVPROD ticket (example) and assign to the team called Release Infrastructure to request the path be created. Then re-run the failingpublish-packages
task. Ask in the slack channel#devprod-release-tools

If this is a new minor release (e.g.

), file a DOCSP ticket to update the installation instructions on Install libmongocrypt. (Example) -
Make a PR to apply the "Update CHANGELOG.md for x.y.z" commit to the
master
branch. -
Update the release on the Jira releases page.
-
Record the release on C/C++ Release Info. This is done to meet SSDLC reporting requirements.
