Description Robert Jenner 2023-10-20 15:27:19 PDT

platform/ios/mediastream/getUserMedia-override-audio-session-interruption.html

is a flaky text failure that is very consistent on iOS. It fails more frequently than it passes. 

HISTORY:
https://results.webkit.org/?suite=layout-tests&test=platform%2Fios%2Fmediastream%2FgetUserMedia-override-audio-session-interruption.html

TEXT DIFF:
 
-PASS call getUserMedia, stop, interrupt and recall getUserMedia
+FAIL call getUserMedia, stop, interrupt and recall getUserMedia assert_true: test after system interruption expected true got false

Comment 2 Robert Jenner 2023-10-20 15:30:19 PDT

I was able to very easily reproduce this failure on iOS17 ToT Release ToT running the test as follows:

run-webkit-tests --ios-simulator platform/ios/mediastream/getUserMedia-override-audio-session-interruption.html --iterations 10 --child-process=1 --force


It fails almost every single time. I was also able to bisect this to a specific regression point. This passes when ran up-to 1000 iterations at 267682@main, but fails with less than 10 iterations at 267683@main


Will be marking expectations below.

I have put up a PR for expectations on this test here:

https://github.com/WebKit/WebKit/pull/19375

But it seems to be slow/lagging on landing. Will forward this bug, and update when the expectation lands.
