Test gardening commit 272259@main (91e45c495707): <https://commits.webkit.org/272259@main>

Reviewed commits have been landed. Closing PR #22015 and removing active labels.

[Philippe Normand]

Most webgl/2.0.0/conformance2/textures/video tests should pass if we enable swrast on the bots. I see it was done for "wpe-platform" but not for the other case. Is there a reason?

The tests time out here, because the rvfc callback doesn't trigger often enough. Enabling force-compositing in GTK3 and swrast in WPE greatly improves the situation... Would such patch be accepted?

[Michael Catanzaro]

Pretty sure this is a dup of bug #264824?

> Pretty sure this is a dup of bug #264824?

Not sure... We have quite a few bug reports about fd leaks and similar...

[Michael Catanzaro]

The critical error is identical. Seems clear enough. If these tests are still broken after bug #264824 is resolved, then presumably it must be due to some other cause now.

*** This bug has been marked as a duplicate of bug 264824 ***

Reopening because my journal is still spammed by these criticals:

It repeats again and again and again, using 2.44.0.

Hit this again today when loading https://www.vox.com/future-perfect/352359/milk-dairy-schools

I wound up enabling fatal criticals in the Epiphany web process, so going forward Epiphany users will only experience a crash rather than destruction of the system journal history. (This bug was the immediate motivation for that change, but I'd been wanting to do it for a while anyway.)

This was probably the best software development decision I've ever made. It's fortunately now just a regular crash instead of a system journal destruction attack.

Seems to happen 100% of the time when loading https://www.cnn.com/. At least, I've just attempted to load the CNN homepage 5 times, and it crashed every time.

[Michael Catanzaro]

Another reproducer: try loading https://www.reddit.com/r/IdiotsInCars/, it will immediately crash Epiphany Tech Preview.

(Warning for in case it doesn't crash: some of the video content there is a little sensitive.)
