Platonides 2e506c4809 PHP >= 5.4.0 started taking advantage of $limit optimization of wfDebugBacktrace(), ... which we weren't treating right. * $limit in wfDebugBacktrace() is the number of returned frames, we thus need to take into account the wfDebugBacktrace() frame, which is sliced from debug_backtrace(). * wfGetCaller() needs to add a level for itself. * MWDebug::warning() was logging itself as the warning issuer, which is useless (the call a few lines before was right, though) MWDebugTest.php changed accordingly. * Removed double call to wfGetCaller( $callerOffset + 1 ) * Documented the meaning of wfGetCaller() parameter * Added unit test Change-Id: Ief50f4c810bad8b03bb2bf9dc6d945d9acb29851		2012-05-31 17:32:33 +02:00
