#5541: File locking broken with File based cache
-------------------------------+--------------------------------------------
Reporter: timr | Type: Bug
Status: new | Priority: Medium
Milestone: 1.2.x.x | Component: File System
Version: RC3 | Severity: Normal
Keywords: | Php_version: n/a
Cake_version: 1.2.0.7692 RC3 |
-------------------------------+--------------------------------------------
I ran into a race condition doing two ajax updates on the same page at
once. It would sometimes give me errors about failing to unlink(). The
errors were kind of like https://trac.cakephp.org/ticket/4370.
To fix it I turned on locking like this:
Cache::config('default', array('engine' => 'File', 'lock' => true));
In both rc2 and rc3 it gave me a large number of warnings about flock
after doing that. It seems someone broke it. So I fixed it. I just deleted
the file_get_contents section, I guess that's some kind of optimization,
but it doesn't work with locking.
The problem was it was trying to lock the file before opening it.
