1301679 - 404 trying to retrieve taskcluster.yml that exists

Status: RESOLVED FIXED

(Taskcluster :: Services, defect)

Description

[Greg Arndt [:garndt]]

It was noticed on a PR that no tasks were kicked off despite a taskcluster.yml existing in the root repo.  This PR has had other tasks kicked off before.

Looking in the logs I noticed:
Sep 09 12:30:00 taskcluster-github app/worker.1: Fri, 09 Sep 2016 12:29:59 GMT taskcluster-github:worker mozilla/balrog-ui has no '.taskcluster.yml'. Skipping.

Which seems to only come from:
https://github.com/taskcluster/taskcluster-github/blob/083568eef832d3bcb926a94f0656b75a23dfa5d6/src/worker.js#L38


It's not immediately clear why it would get a 404 for a file that exists in the root repo.  Perhaps we need to do some investigation and maybe add some more logging to understand.  I'm also not sure how we can bubble up this error to the originating PR so that they have more information to go off of.

This seems to be working fine from pushes and PRs submitted to the taskcluster org (specifically the taskcluster-github project). Perhaps we should look into the permissions of the tc-robot in the mozilla org?

This appears to be an intermittent thing. I've added more logging and tried to improve things a bit, but we'll just have to wait and see. Unfortunately getting 400 on this page is actually normal and expected so we can't just alert on it every time.
