i think this is default now, and you have to opt out. This has nothing to do with cq though, but gerrit label config and chumpdetector.

You set your repo to inherit settings from infra/infra (which you shouldn't do, btw -- only inherit from "parent" projects like infra, not "leaf" projects like infra/infra). That means that you get all the same settings as your parent project: same labels, same plugin configs, everything. So you have the CQ label, and you have chumpdetector telling you to not to skip the CQ.

There are a few appropriate fixes here:
1) Make it inherit from infra, and then add config to your leaf project to disable the CQ label and chumpdetector (I can show you how to do this if you like)
2) Make it inherit from infra, and give it a real CQ
3) Make it inherit from something else appropriately experimental, like the 'playground' parent repo, and then just add the ACLs you need

As a git admin, I'll leave the resolution up to you :)

Thanks! New area for me and I didn't set this up. I'll poke around in there and probably go for option 3 :)

After more consideration, I'll go with option 1. How do I disable the CQ label?

Disable the CQ label with a change like this: https://chromium.googlesource.com/infra/gerrit-plugins/+/6ebbf202f7e81cc2d016e235fbd20f0978d6508c

Disable the chumpdetector from complaining about you not using the CQ with a file like this:
https://chromium.googlesource.com/infra/gerrit-plugins/+/c36fec2133d174125325e00c3c95ed911a4326f2/chumpdetector.config

I guess links to the files at HEAD are more useful:

https://chromium.googlesource.com/infra/gerrit-plugins/+/refs/meta/config/chumpdetector.config

https://chromium.googlesource.com/infra/gerrit-plugins/+/refs/meta/config/project.config#7

Edited project.config via https://chromium-review.googlesource.com/c/557801/ didn't manage to checkout refs/meta/config on a local branch. How do I get this setup?

$ mkdir /tmp/meta/myrepo
$ cd /tmp/meta/myrepo
$ git init
$ git remote add origin https://chromium.googlesource.com/myrepo
$ git config remote.origin.fetch +refs/meta/config:refs/remotes/origin/refs/meta/config
$ git fetch origin
$ git checkout origin/refs/meta/config
$ # edit and commit
$ git push origin HEAD:refs/for/refs/meta/config

Thanks Aaron!
