• Resolution: FIXED
• Component: WPE WebKit

/WPE/TestWebExtensions
    /webkit/WebKitWebView/web-process-crashed

First failure: 237336@main (r277020) in build: https://build.webkit.org/#/builders/40/builds/1542

libWPE and WPE-backend FDO updated respectively to 1.10 and 1.9.91 in 237333 (r277017), and picked up first by the build above.

Could not reproduce the issue with SDK version r276635 locally but SDK version r277017 indeed it's flaky.

Gardened in r277157

[Adrian Perez]

The crash here I suspect is caused by the test being run with
“G_DEBUG=fatal-warnings” but I don't remember if the test harness
does that. At any rate, we are working on plugging a regression
in https://github.com/Igalia/WPEBackend-fdo/pull/158 and once
that is solved we should remove this warning from WPEBackend-fdo.
Pablo Saavedra and myself are actively working on this but progress
has been slow so I cannot give you a certain ETA… maybe we should
consider downgrading WPEBackend-fdo back in the meantime.

SDK r277166 is deployed but I haven't updated test expectations yet.
