Bug 232629 – [GLIB] Many network process crashes when running WPT tests

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Martin Robinson]

When running WPT tests locally the network process crashes continuously. This only appears when running more than one test at a time and with the WebKit Flatpak build.

A message is printed:

STDERR: (process:538): GLib-CRITICAL **: 10:07:18.446: Failed to set scheduler settings: Operation not permitted

Here is the core dump:

STDERR: (process:538): GLib-CRITICAL **: 10:07:18.446: Failed to set scheduler settings: Operation not permitted

[Philippe Normand]

That might be related with the RTKit stuff landed recently I think.

[Philippe Normand]

Does this crash happen also after reverting r284525 ?

[Carlos Garcia Campos]

(In reply to Philippe Normand from comment #1)
> That might be related with the RTKit stuff landed recently I think.

Why do you think it's related? I don't think there are user interactive threads in the network process

[Carlos Garcia Campos]

Oh, I see STDERR: (process:538): GLib-CRITICAL **: 10:07:18.446: Failed to set scheduler settings: Operation not permitted

[Martin Robinson]

I can confirm that reverting the patch that Philippe mentions fixes this issue.

[Carlos Garcia Campos]

I don't think it's rtkit in any case, because there aren't user interactive threads in the network process and we don't use g_error when it fails. That message comes from GLib and it might be this  https://gitlab.gnome.org/GNOME/tracker/-/issues/180

[Lauro Moura]

FTR, I'm also getting this crash consistently with the following non-WPT test locally:

http/tests/media/media-blocked-by-willsendrequest.html

In the bots, it timeouts instead.

Patch to workaround the issue

[Carlos Garcia Campos]

Reopening because landed patch is just a workaround.

[Michael Catanzaro]

Note that isInsideFlatpak() always returns true in the NetworkProcess when the sandbox is enabled, since it just checks for /.flatpak-info, which gets created by BubblewrapLauncher.cpp even if you're not running inside flatpak.

Is it caused by selinux?

But we are not sandboxing the network process

[Michael Catanzaro]

Oh yeah, nevermind. :P
