piman@: The "Choose try jobs" popup includes instructions for adding bots to the list. Please see if you can do it yourself, and provide feedback to me on what pieces of the process you find confusing/difficult.

We have plans (https://bugs.chromium.org/p/chromium/issues/detail?id=70609) to make this much easier in the future but for now can you give it a shot? Thanks!

Moved issue gerrit:6193 to now be  issue chromium:721483 .

I have to say I'm not sure where to start. It suggests editing a file which doesn't seem to exist in the top-of-trunk repository. Looking closer, I think it's referring to a branch "refs/meta/config" which I don't have locally under remotes/origin (I see infra/config, is that the same?)

Fair enough. A simple "git fetch origin refs/meta/config && git checkout FETCH_HEAD" would get the file for you.

Hopefully we'll soon have online editing, so you wouldn't even need to do that.

I think I need a bit more hand holding...

Did the above, edited the file, committed.
git cl upload --gerrit says I can't upload because I'm not on a branch. Fair enough, create a branch 'add_gpu_trybots'.
Then git cl upload --gerrit fails (crashes) because it can't find the merge base. Fair enough, I create a base branch with 'git fetch origin refs/meta/config:meta/config' and then git branch -u meta/config on my 'add_gpu_trybots' branch.
Then git cl upload --gerrit fails saying I need to upload meta/config first. Which I can't do (same issue as previous step).

Ok, I think I managed to do it: https://chromium-review.googlesource.com/c/503452/

For posterity, I did 'git fetch origin refs/meta/config:refs/remotes/origin/refs/meta/config', then git branch -u origin/refs/meta/config and then 'git cl upload --gerrit'

They show up now, thanks!

*whew* I'm glad you were able to figure it out. And thanks a ton for the feedback -- I'm so immersed in the world of git that I don't have a good sense of what is easy and what is confusing anymore.

And by the beauty of instant config deployment, your new bots already show up in the 'Choose try jobs' box :)
