Bug ID: 64529
Summary: htcacheclean silently returns success on insufficient
permission
Product: Apache httpd-2
Version: 2.4.41
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_cache
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Documentation at https://httpd.apache.org/docs/2.4/programs/htcacheclean.html
states:
> htcacheclean returns a zero status ("true") if all operations were
> successful, 1 otherwise.
If a user has access to /var/cache/apache2/mod_cache_disk/ but no access to
subdirectories (= no read/write permissions on the cache), as it's the case on
Debian-like system:
- On actual clean attempts does "An error occurred, cache cleaning aborted"
- But for read operations, htcacheclean behaves like if there was an existing
but empty cache: List no entries, returns 0.
=> There is no way to differentiate between a lack of permissions and an empty
cache.
NB: I hope one day we'll have a PHP-Apache function to clean the cache straight
from PHP ;)
