1583955 - Track down the leak in helper_overscroll_behavior_bug1425573.html

Status: RESOLVED FIXED

(Core :: Panning and Zooming, task, P3)

Description

[Botond Ballo [:botond]]

In bug 1567448, we identified the APZ subtest helper_overscroll_behavior_bug1425573.html (which runs as part of the test test_group_wheelevents.html) as intemittently causing a memory leak, and disabled the subtest for now.

This bug tracks investigating and fixing the leak, and re-enabling the subtest.

There are some logs in bug 1567448 comment 20, and instructions for how to use them to find the leak in bug 1567448 comment 42.

If you manage to catch this leak in pernosco, I have some pointers for how one could track it down manually, similarly to how find_roots.py would check the cc log.

If that doesn't work, I also have a patch to turn on DMD and CC logs on shutdown for mochitests.

There's no test-verify job for qr builds on try, so I'm not sure what's needed to repro this in a smaller job. mochitest-e10s-12 might be a way too, though.

It no longer seems to be leaking.
