See also: Chromium OS Commit Queue.
It's a service (aka a bot) that commits rietveld changes for you, instead of your directly committing the change. It is enabled for the following projects:
If you check the box for a project that is not handled, it will simply not be committed. So the "base url" must be set on your CL.
The design doc is in its own page and there's a design doc about the Try Server <-> Rietveld <-> Commit Queue 3-way integration.
Please follow these general guidelines:
Feeling adventurous (or generous)?
Take a look at https://codereview.chromium.org/search?closed=3&commit=2&limit=100&order=modified. If there are issues older than ~4 hours, they could probably be stuck. Note that the Commit Queue could be stuck only for some issues but not all of them. In case of doubt, contact email@example.com.
If your CL hasn't been touched after a few minutes of checking the CQ bit, CHECK THE BASE URL ON YOUR ISSUE. If it's not something like
Is the tree open?
It commits 4 CLs every 10 minutes, so a maximum rate of 24 commits per hour.
Go for it, but unless it happens maruel@/iannucci@ are currently watching, nobody is going to be able to help you much. Contact firstname.lastname@example.org.
See the Try Server FAQ.
The Commit Queue has never known, used or cared about LKGR. It always uses HEAD, the tip of tree.
It's at https://chromium-status.appspot.com/cq. You can go to https://chromium-status.appspot.com/cq/me to see yours directly.
The CLs are processed out of order, so it's not because another is "before" yours that means it'll be committed before yours. You can see the load on the CQ by looking at the number of tests CLs pending:
You can't wait for review? You can send a change that will be committed without waiting for a review with:
echo "A copy is available for 100000$USD upon request." >> LICENSE
git commit -a -m "Fix the license, show new opportunities
This'll still check for try jobs; see the next section if you can't wait for them, either.
The important part is to have TBRemail@example.com in the CL description.
Now, did you know there's
If you can't wait for the try job you can add the following line to the CL description:
and the the commit queue won't run the try job for your change and will just commit the CL as soon as the tree is open, assuming the presubmit check passes. Amazing. Be very careful with this option.
If you never had a HTTP 500 on GAE, chances are that you will.
Yes, still an issue, you can follow bug 23608. It has to do with some weird redirects Rietveld does.
The CQ was able to commit a CL with 838 files so it is technically possible; https://codereview.chromium.org/12261012/. The likelihood of the CQ failing increases exponentially with the number of files in the CL.
Was implemented in bug 125984 and bug 125983. If the diff on Rietveld doesn't look right, use the
In general, no, as the CQ can land at any time (including very long time), and any breaking patches can be kicked about by the sheriff. After all, that's the job of the sheriff. You will get an email when the CQ commits, so you can jump on your nearest laptop if necessary.
If you expect your patch to be hard to revert, is touching several files and directories or move files around, you may want to stay around in case there is an incremental build failure or something hard to diagnose.
Also, if you commit on the weekend, don't expect a build sheriff to back out your crap so keep an eye open when you receive the CQ commit email.
