1594878 - Keep Fission processes alive in browser/components/uitour/test/

Status: RESOLVED FIXED

(Core :: DOM: Content Processes, task, P2)

Description

[Andrew McCreight [:mccr8] (PTO until 12-2)]

About a third of the last 100 hangs in bug 1358898 are in the browser/components/uitour/test/ directory. As a work around, I'll try keeping Fission processes alive, as I did in bug 1580212 for another directory.

(This accounts for the failures in mochitest-browser-chrome-fis-e10s-7.)

There are a lot of intermittent hangs in this directory when Fission
is enabled. Keeping processes alive should avoid these.

For some reason, the chunk that uitour was showing up in is different than the failures, so it took me a bit to get the right one (bc3), but with this patch I wasn't able to reproduce the shutdown hangs. The rate is a little lower than the other one so it is hard to know for sure if that means it is fixed.

Retroactively moving fixed bugs whose summaries mention "Fission" (or other Fission-related keywords) but are not assigned to a Fission Milestone to an appropriate Fission Milestone.

This will generate a lot of bugmail, so you can filter your bugmail for the following UUID and delete them en masse:
