1864971 - Windows XPCShell code coverage tests aborted - "max run time exceeded"

Status: RESOLVED FIXED

(Thunderbird :: Testing Infrastructure, defect)

Description

[Geoff Lankow (:darktrojan)]

Several of the Windows CCov tasks are still timing out every push. Even the ones that do run take an age. I have two ideas:

• Get some Windows machines with SSDs like mozilla-central uses for ccov tasks. These tasks do huge amounts of file I/O and that's why the tasks take so long.
• Only run the tests from comm-central in code coverage (either everywhere or just on Windows - Linux tests don't have this problem). It's unlikely the toolkit tests provide any useful coverage information for our code. This could be achieved by adding a tag to all of the xpcshell.ini manifests, and changing the test config to run only tests with that tag.
• Both?

I thought I'd set this needinfo already. No wonder I didn't get a response!

Rob, is option 1 above feasible?

Most likely. I'll have to check.

So the answer to option 1's feasibility is "yes".

[Geoff Lankow (:darktrojan)]

Woohoo!

All the tests on your Try run finished within 45 minutes, which is definitely less than 2 hours. Hopefully that means more reliable data.
