Issue status update for http://drupal.org/node/23100

 Project:      Drupal
 Version:      4.6.0
 Component:    file system
 Category:     bug reports
 Priority:     critical
 Assigned to:  drumm
 Reported by:  drumm
 Updated by:   drumm
 Status:       patch
 Attachment:   http://drupal.org/files/issues/file.inc_4.diff (1.04 KB)

Conditions to reproduce:
- 'Temporary directory' on the admin/settings page is configured to
something not starting with the configuration of 'File system path'.
For example, the default '/tmp' does not start with the default file
system path 'files'.
- There are not directories named the same as the temporary directory
in the file system path. In the above example, path/to/drupal/files/tmp
should not exist.

What happens:
1. file_create_path('/tmp/something') is called.
2. file_check_location('/tmp/something', 'files') returns false.
3. Fall back to file_check_location('files//tmp/something', 'files'),
which does one of two things:
- if path/to/drupal/files/tmp exists that is happily used, ignoring the
admin's configuration, and things work.
- otherwise the whole thing returns FALSE and a bunch of stuff up the
stack gets horribly confused.

Lets add in another check to see if the file is in the temporary
directory between steps 2 and 3.
