Description Martin Robinson 2021-11-02 10:32:14 PDT
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:

Comment 1 Philippe Normand 2021-11-02 11:43:47 PDT
That might be related with the RTKit stuff landed recently I think.
Comment 2 Philippe Normand 2021-11-02 11:45:41 PDT
Does this crash happen also after reverting r284525 ?
Comment 3 Carlos Garcia Campos 2021-11-03 01:32:47 PDT
(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
Comment 4 Carlos Garcia Campos 2021-11-03 01:33:08 PDT
Oh, I see STDERR: (process:538): GLib-CRITICAL **: 10:07:18.446: Failed to set scheduler settings: Operation not permitted
Comment 5 Martin Robinson 2021-11-03 01:36:47 PDT
I can confirm that reverting the patch that Philippe mentions fixes this issue.
Comment 6 Carlos Garcia Campos 2021-11-03 01:37:42 PDT
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
Comment 7 Lauro Moura 2021-11-04 14:16:44 PDT
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.

Reopening because landed patch is just a workaround.
Comment 12 Michael Catanzaro 2021-11-23 06:16:51 PST
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.
Comment 13 Michael Catanzaro 2021-11-23 06:17:47 PST

Is it caused by selinux?

But we are not sandboxing the network process

Oh yeah, nevermind. :P
