Bug 1641395 - install amd64 variants of existing i386 packages and insert additional startup parameters for pulseaudio
47 bytes, text/x-phabricator-request
Details | Review

This bug is split from Bug 1633101.

Synopsis

Currently, in-tree docker test image setup script installs the i386 variant of fontconfig.

This was causing slow Firefox startup issues in the puppeteer tests. The solution to the slow startup issue is to install the amd64 variant of fontconfig. This causes the issue documented in this bug.

Problem

try push:

Replacing fontconfig:i386 with fontconfig:amd64 appears to cause the mochitest-media chunk that runs the manifest dom/media/tests/mochitest/mochitest.ini to experience a series of permafail and crash in libxul.so!mozilla::gmp::GMPChild::ProcessingError.

:gsvelto performed an analysis of this crash dump in this comment and found it could be the test is looking for a plugin file that does not exist.

:bryce looked at the plugin referenced, fakeopenh264 and GMP in general in this comment. This is as far as analysis of the root cause of this failure has gone.

The crash itself:

Summary: media-related tests experience intermittent crashes or failures → intermittent crashes or failures of media-related on ubuntu1804
Attachment #9152261 - Attachment is obsolete: true

I have been attempting to find patterns that can lead to an answer for this, but it appears that anytime I try something, the results do not stay consistent between successive changes.

For example, in this push the only change was fontconfig. This change causes several chunks across the mochitest suite to intermittently hit the codepath at mochitest/runtests.py which implies that pulseaudio is not running, but mochitest-media tests pass as expected.

However, in a push prior to the above, with the exact same changeset, mochitest-media experiences a crash.

The only difference between the two pushes are the base revisions, but the behavior is inconsistent given the changes were identical in the two.
