When tasks are aborted, an error message is appended to the task log, but it's not in a format that TH recognized. In 1174557 a regex was added for lines starting with "[taskcluster] Error:". Update docker-worker to work with this. Right now it's just "[taskcluster] <some message>"

Also part of this was moving the logger to be created on 'link' instead of 'created' to ensure it's available

I got this from the sheriffs mailing list, before this I was not aware there is a Tree Herder API for reporting errors, maybe this is an interesting option, not sure...

Treeherder supports the ability for TC to directly submit all the job/error information via an API, so it wouldn't have to parse TC logs at all, but this would require some extra work on the TC side. I'm trying to evaluate the priority of that work. Do we see a lot of problems related to parsing of TaskCluster logs that would theoretically be addressed if TC started posting all of the job and error information directly to Treeherder? Or is it more a matter of little paper cuts?

:pmoore Thanks for adding this. We definitely should make use of this for some things. Such as when a task has run and deadline has been exceeded. I'm wondering if some way the deadline resolver (or something else) could post the error to TH when this happens. In this instance, it was easy to just add the word "Error: " to something we were logging anyways to hopefully give some info for the sheriffs.
