• Component: New Bugs
• Status: RESOLVED CONFIGURATION CHANGED

[Matt Lewis]

The following layout test is failing on iOS Release WK2

editing/pasteboard/data-transfer-set-data-sanitizes-html-when-copying-in-null-origin.html

Probable cause:

The first timeout occurred with this build:
https://build.webkit.org/results/Apple%20iOS%2011%20Simulator%20Release%20WK2%20(Tests)/r227743%20(2829)/results.html

The timeouts had lessened after this final build:
https://build.webkit.org/builders/Apple%20iOS%2011%20Simulator%20Release%20WK2%20(Tests)/builds/2995


However after this revision the timeouts increased:
https://trac.webkit.org/changeset/228240/webkit

[Wenson Hsieh]

It doesn't seem like there's a dramatic increase in the number of timeouts.

I also wouldn't expect that revision to have any impact here, especially because filepaths in the pasteboard don't even play a role in this test…

[Ryan Haddad]

Skipped test on iOS Release bots in https://trac.webkit.org/r228699 because this is timing out very frequently.

This doesn't seem to be happening in recent builds.
