WebKit's commit-queue bugzilla-tool command which is run on the commit server (maintained by Eric Seidel) and is an easy way for contributers without commit privileges to get their changes into WebKit.
Commit Queue Process
- Contributer set "commit-queue=?" on their patch.
- Committer sets "commit-queue=+" in response.
- commit-queue polls bugzilla for the list of cq+'d patches, finding one it runs
bugzilla-tool land-patches
on the bug in question.
Commit Queue FAQ
Q: What do the commit-queue states mean?
- commit-queue=+ Patch is 100% ready for commit, the commit bot should land it.
- commit-queue=- Patch needs manual landing (set this when you don't want any chance of auto-commit).
- commit-queue=? Set by non-committers to ask someone to approve their patch for auto-commit.
Q: Who can set commit-queue+ or review+?
bugzilla-tool
validates that the flag setters are committers/reviewers using:
http://trac.webkit.org/browser/trunk/WebKitTools/Scripts/modules/committers.py
Q: How long until a patch lands after I set commit-queue+?
10-15 minutes. Depends on if the tree is red or not. The commit-queue will not commit when buildbots for the core platforms are red.
Q: My patch was rejected by the commit queue, what should I do!?
First, read the comment the commit queue added to the bug. If the message is not clear, feel free to email the WebKit Commit Bot address in the bug. There are outstanding bugs about making the commit bot's messages more clear.
Sometimes the commit-queue rejects patches due to flakey tests. Don't worry, whoever is running the commit queue should add your patch back to the queue if it was wrongly rejected.

Q: How can I see what's in the commit-queue?
bugzilla-tool bugs-to-commit
is how the commit-queue checks. That will print out any pending bugs.
Q: What checks does commit-queue do before landing?
Everything bugzilla-tool land-patches
does. Which is build-webkit
(on Mac) and then run-webkit-tests
. The commit-queue also checks http://build.webkit.org/ to make sure that all of the Leopard and Windows builders are green. If you would like it to do more, please file bugs and post patches to bugzilla-too
l! :)
Q: When I review a patch, should I set commit-queue+?
If you would like the commit bot to land the patch, yes.
Q: Help! The commit queue broke the tree! Who do I blame?
Setting commit-queue+ on a patch is the moral equivalent of typing "svn commit" on the command line. That means whoever set the flag to + is responsible for watching the tree and cleaning up if disaster strikes.
Q: When I don't want my patch to be auto-landed, what should I do?
You don't need to do anything. Only commit-queue+ patches are auto-landed. Setting commit-queue- will make extra-sure.
Q: If I want my patch landed, and I'm not a committer, what do I do?
Set "commit-queue=?". A committer can set it to commit-queue+
Q: What does cq+ mean?
Some of us have been shortening commit-queue to "cq" when typing, so cq+ is "commit-queue=+". Similar to how r+ is "review=+".
Q: Can I run the commit-queue myself?
Yes. Any committer could run the commit queue. bugzilla-tool commit-queue
The commit queue is not designed to have more than one copy run at a time though.
Q: Does the commit-queue fix the "Reviewed by NOBODY" in any ChangeLogs in the patch?
Yes bugzilla-tool
calls svn-apply
which does. It sets the reviewer based on who marked the patch as r+. It also updates the date for the changelog entry.
