note 45897 added to function.flock

Creating lock files and testing for their existence is absolutely wrong, NFS or not. The only file operations that are guaranteed to be atomic are mkdir() and symlink(). And those aren't atomic over NFS (or other network filesystems) either. Short answer: create lock directories, not files. Don't stat the directory to test, simply try to create it and see if it fails. And all locking bets are always off with NFS. ---- Manual Page -- http://www.php.net/manual/en/function.flock.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+45897 Delete -- http://master.php.net/manage/user-notes.php?action=delete+45897&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+45897&report=yes Search -- http://master.php.net/manage/user-notes.php
