tandrii: is something missing in https://chromium.googlesource.com/external/webrtc/+/master/infra/config/cq.cfg ?

What's your depot_tools revision?
  $ cd $(dirname `which gclient`); git rev-parse HEAD

What happens if you checkout latest HEAD of depot_tools? If you can help bisect it, it'd appreciated. Otherwise, tell us exactly how you invoke git cl try.

At first, I thought https://chromium.googlesource.com/chromium/tools/depot_tools/+/e4f0fe02a97d526b565fc13152436f6f165e05c6 should have fixed your problem.

I can reproduce this as well. Here's the requested information:

$ git cl try
ERROR: Access denied: User user:kjellander@webrtc.org cannot add builds to bucket master.master.tryserver.webrtc
$ git cl try -m tryserver.webrtc
ERROR: Access denied: User user:kjellander@webrtc.org cannot add builds to bucket master.master.tryserver.webrtc
$ cd $(dirname `which gclient`); git rev-parse HEAD 
600d9dfd1a3a7a9b1ece14def1850eca4dc3f38d

Which seems to be the HEAD according to https://chromium.googlesource.com/chromium/tools/depot_tools/
Notice that when specifying a bot, it works:
$ git cl try --bot=linux_compile_rel -m tryserver.webrtc
Tried jobs on:
Bucket: master.tryserver.webrtc
  linux_compile_rel: []
To see results here, run:        git cl try-results
To see results in browser, run:  git cl web

This sounds very familiar to the previously reported  bug 658317 .

OK, here is what happened:

WebRTC PRESUBMIT.py has GetPreferredTryMasters which returns buckets from cq.cfg as if they were masters. However, 4 months ago i updated buckets in cq.cfg to be actually buckets (ie master.tryserver.x OR luci.try.X) not master names (ie tryserver.x). qyearsley@ recently cleaned up guessing in git cl try code and assumed GetPreferredTryMasters returns master names, hence you get double "master." prefix.

Henrik, can GetPreferredTryMasters be removed? git cl try would then just trigger CQ dry run directly. That would resolve this bug.

CL: https://codereview.webrtc.org/2486743002

and with this CL I can try it:

Using 50% similarity for rename/copy detection. Override with --similarity.

Ah, and since I clearly don't have access to CQ dry run, also this change to cq.cfg so more people can run CQ dry run:

The following revision refers to this bug:
  https://chromium.googlesource.com/external/webrtc.git/+/4fcc4d83ea41bc4476d8f5ddc5a03bbe0ef3500f

Expand CQ dry run permission to people with tryjob access.

The group is project-webrtc-tryjob-access provided by

https://codereview.webrtc.org/2489523003/ missed to prefix chromium: for the BUG field so it wasn't posted here.

I can confirm it now works:
$ git cl try
scheduled CQ Dry Run on https://codereview.webrtc.org/2488673002

Thanks tandrii!

Could you please set the correct milestone for this issue?
