Description

Warning: array_map() [<a href='function.array-map'>function.array-map</a>]: An error occurred while invoking the map callback in /usr/local/apache/common-local/php-1.22wmf3/includes/resourceloader/ResourceLoaderFileModule.php on line 611

Seems this hasn't been reported before, or if it was, maybe closed.

The number of these warnings seem to have incrased quite a bit with 1.22wmf3 being deployed to the testwikis

Version: 1.22.0

Reedy: Any approx. numbers before and after?
"quite a bit" does not help to judge whether this is important or not...

The warning can happen, when the callback throws a exception. In line 611 (now 607) the method $this->readStyleFile is called, which can throw a exception.

Are there log entries in group 'resourceloader' which have the text "style file not found:"?

Reedy: per bug 49757 (better monitoring of errors), we can use this specific issue as a test case.

Can you determine if the number of these has gone up/down since you first reported it in April?
