Bug 296313 – Parallel calls to [WKContentRuleListStore compileContentRuleListForIdentifier:] for the same identifier can fail

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Chris Dumez]

Parallel calls to [WKContentRuleListStore compileContentRuleListForIdentifier:] for the same identifier can fail. This is because we process the requests on a concurrent work queue and different threads may thus end up interacting with the same file.

Hi Chris, has the fix rolled out to any of the recent betas? Because we're still seeing failures in the August 5 beta.

Hi Chris,

Regarding the duplicate Bug 296191 :

We see around 20% of failures happening on 23A5308g and 51% of the failures are on 23A5297m

This does not imply any stability improvement and could be due to the size of the user base on the different betas.

We currently see very few failures on 23A5318c but this could be attributed to a low user base since this is a very recent release, or due to delay in data.
