The documentation and class uses the name "umask" for what is not an umask (see umask(2) man page for the definition : "umask() sets the calling process's file mode creation mask (umask) to mask & 0777"). Rather, the Zend_Cache_Backend_File uses the option "cache_file_umask" to chmod ( the file. In effect this is an octal permission definition rather than a umask.

This is quite misleading.

Indeed. I've updated the documentation (inline and manual) to make note of the fact that the option name contains 'umask' but intent is actually octal file mode:

Be aware that you are not mistakenly passing a umask value, which is the inverse of the file mode.  The file mode defines the permissions to grant, whereas umask defines the permissions not to grant.

moved to Zend_Cache

Added patch: - added *_perm options - *_umask triggers E_USER_DEPRECATED error and move value to *_perm options

Posted by Marc Bennewitz (private) (mabe) on 2012-03-12T21:29:37.000+0000

fixed for 1.12 in r24677 (trunk)

Posted by Marc Bennewitz (private) (mabe) on 2012-03-12T21:31:00.000+0000

note: triggers E_USER_NOTICE instead of E_USER_DEPRECATED because E_USER_DEPRECATED doesn't exist on PHP < 5.3
