The transition of the 8u repositories from Mercurial to git was completed after the April 2022 release, on Monday, April 25th.
OpenJDK 8 updates will be delivered on the same established quarterly cycle used by Oracle i.e. "the Tuesday closest to the 17th day of January, April, July and October."
Announcements and discussion take place on the jdk8u-dev mailing list. Development takes place in the jdk8u-dev git repository and should be the primary place for OpenJDK 8u committers to submit their work.
Code from the development repository is regularly tagged and promoted to the main jdk8u repository, which is used to stabilize and deliver the quarterly releases. Distributors should use this as their primary source for creating OpenJDK builds.
For further process details, you may want to continue reading here.
New fixes should first be submitted to the development repository for the current version of OpenJDK, jdk/jdk, first. The vast majority of changes submitted to the OpenJDK 8 project will be backports from later OpenJDK versions. The version of OpenJDK closest to 8u should be used to minimise the differences between the two JDKs e.g. if 11u is still maintained and has the patch, it should be backported from that repository, rather than jdk/jdk. Occasional exceptions are made when an issue only applies to 8. In particular, the build system can be quite different from that in later versions, especially as regards HotSpot.
Everybody is encouraged to submit fixes for OpenJDK 8 updates by using the SKARA processes now common to all OpenJDK projects. Established community members will help new developers without commit access in getting their patch reviewed. Should you not be willing or not be able to drive a fix into OpenJDK 8 updates, you can still suggest changes. But by only doing that, you are at the grace of the community to pick up your suggestion.
The suggested process is as follows:
- Check the bug database for which JDK versions already have the patch applied.
- When actively starting working on the bug, add a label of the form 'jdk8u-<username>', to the bug - where <username> is your OpenJDK username - to indicate that you are creating a backport.
- Take a copy of the patch from the repository of the JDK version closest to 8u to minimise changes.
- 8u is now a single repository, so there should be a 1:1 relationship between patches to later JDKs and 8u patches, rather than multiple patches for individual sub-repositories. However, file locations are highly likely to be different on 8u, especially with changes for the modular JDK in later versions, so automated backports via SKARA won't work. If the patch was developed after the switch to the modular system (during the OpenJDK 9 lifecycle) and is not a HotSpot fix, shuffle the paths using <jdk9>/common/bin/unshuffle_patch.sh <repo> <9.patch> <8.patch>. An updated version of this script is maintained in Andrew Hughes' jdk9u-updated branch on github.
- Try to apply the patch by using
git cherry-pickas documented in the Skara backporting process. If it applies, go to #8. Otherwise, #7.
- Fix the patch so it applies. This may require identifying other patches which need to backported first, in which case you start this process again with that fix.
- Build the resulting JDK and/or run any new or modified tests, altering if necessary. Again, this may end up needing dependent backports to fix issues that arise.
- Create a pull request on GitHub as described in the Skara documentation. The pull request should use the title "
Backport <x>" where
<x>is the hash of the original commit. This ensures that the PR is correctly recognised by Skara as a backport and bugs updated appropriately.
- Wait for testing to complete and a successful review from an OpenJDK 8u reviewer.Go
- Request for approval of the bug to go into OpenJDK 8u. You can do this either by using the Skara /approval command for which you don't need to have access to JBS, or go to the bug in JIRA and add the 'jdk8u-fix-request' label. Write In either case, be sure to include proper reasons as to why you think that fix needs to get into OpenJDK 8u. Do this either by writing a comment preceded with "Fix Request [8u]" or using the "/approval <comment>" approach. Explain the motivation for the fix, and either explain that it applies cleanly to 8u with patch shuffling, or refer to the GitHub review process. If you don't have bug database access, someone will need to do this on your behalf. In the case that the bug is inaccessible (the page displays "You can't view this issue"), please make the request by e-mail to firstname.lastname@example.org with the subject "RFA: <bug ID> <bug description>" and the same motivation in the body of the e-mail as would have been included in the request comment. It may also be worth replying to the original review thread, asking for the bug to be made public.
- Wait for an 8u maintainer to add jdk8u-fix-yes to the bug.
- The change can now be pushed to the jdk8u-dev repository using the Skara
/integratecommand. If you are not yet an OpenJDK 8u Committer, you may need to wait for someone who is to issue the
- Pat yourself on the back, having successfully got a patch into OpenJDK 8u.
Backport bugs will be automatically created on push. If a backport bug needs to be explicitly created - for example, for a Compatibility and Specification Review (CSR) - then please apply labels to that bug to avoid the need to work on two different bugs for the one issue. The fix version should be set to 'openjdk8ux' where x is the current version of 8u being developed. Please avoid using 'openjdk8u' as such bugs will not be resolved automatically. Maintainers should double-check this fix version is correct when approving.
In general, we follow the common rules for the jdk-updates project.
If the backport does not apply to the 8u tree via the automated shuffling described above, it should first be submitted for review.
Push approval for a fix is then requested by setting the jdk8u-fix-request label on the original JBS bug. The maintainer will either approve this by setting jdk8u-fix-yes or reject it by setting jdk8u-fix-no. Outstanding approvals can be monitored here. If, and only if, the fix is approved, it may be pushed to the appropriate jdk8u-dev repositories. Approved fixes show up in this JBS filter (login required).
During the later stages of a release cycle, the release enters rampdown. The master jdk8u repositories contain the latest version of that release, while the jdk8u-dev repositories are used to start work on the next release. If a change needs to be pushed to a release in rampdown, push approval can still be requested using the jdk8u-critical-request label. As the name of this tag suggests, this process is intended for fixes such as major regressions that must make the release. More minor bugs and new features should go in the next release being developed in jdk8u-dev. The maintainers may approve with jdk8u-critical-yes, defer to jdk8u-dev or reject altogether. Outstanding approvals for critical fixes can be monitored here. If, and only if, the fix gets approved with jdk8u-critical-yes, it may be pushed to the jdk8u repository. Approved critical fixes show up in this JBS filter (login required).
At the end of the month prior to the release month, the jdk8u repository is declared frozen, so embargoed security fixes can be added in private during the final few weeks. On release day, the final version will be pushed to the jdk8u repository and source bundles made available.
Some filters will only work for users that are logged into JBS.
