Bug #64306 sometimes rmdir() doesn't really remove folder if WinCache extension enabled
Submitted: 2013-02-27 05:36 UTC Modified: 2013-11-20 22:20 UTC

Description:
------------
rmdir() function is intercepted by WinCache extension and replaced by its own implementation. Before original rmdir() is called, wincache tries to lookup directory passed to rmdir() in filecache (aplist_fcache_get function) and if this lookup is failed by some reasons, then original function is not even called. And directory is not removed in fact.

After enabling debug in php.ini and some experiments I've detected that aplist_fcache_get can return FATAL_OUT_OF_SMEMORY error. If this happened, directory is not removed.

I think this is not valid behavior, and original handler should be called, if specified location cannot be found in file cache.

I have applied patch that returns error after original handler is called.
