When removing graphs, RRA files may be left behind

[morganfw]

Describe the bug

When try to remove Orphaned Graphs from GUI, following error is written to the log:

2024-10-17 08:55:23 - MAINT <path_rra>/myrrd_73499.rrd ERROR: RRDfile Maintenance unable to delete from /var/www/html/cacti/rra!
2024-10-17 08:55:23 - CMDPHP PHP ERROR WARNING Backtrace: (/poller_maintenance.php[98]:rrdfile_purge(), /poller_maintenance.php[272]:remove_files(), /poller_maintenance.php[560]:unlink(), CactiErrorHandler())
2024-10-17 08:55:23 - ERROR PHP WARNING: unlink(/var/www/html/cacti/rra/<path_rra>/myrrd_73499.rrd): No such file or directory in file: /var/www/html/cacti/poller_maintenance.php on line: 560

we think the path cannot be found because <path_rra> is added to the path string.

If we check in the path the file exists:

cacti:/var/www/html/cacti/rra# ls -latr myrrd_73497.rrd
-rwxrwxr-x 1 www-data www-data 95608 Oct 17 07:20 myrrd_73497.rrd

If we check on Console - System Utilities - RRDfile Cleaner then click on Rescan, the table will be populated.

To Reproduce

Steps to reproduce the behavior:

1. Go to 'Console - Management - Graphs'

2. Flag on 'Orphaned'

3. Select all Orphaned Graphs - Choose an action "Delete" and click "Go"

4. Error in Logs - cacti.log:

2024-10-17 08:55:23 - MAINT <path_rra>/myrrd_73499.rrd ERROR: RRDfile Maintenance unable to delete from /var/www/html/cacti/rra!

5. If we check in the path the file exists:

cacti:/var/www/html/cacti/rra# ls -latr myrrd_73497.rrd
-rwxrwxr-x 1 www-data www-data 95608 Oct 17 07:20 myrrd_73497.rrd

6. No Orphaned Graphs in Cacti GUI (see screenshot)

7. If we check on Console - System Utilities - RRDfile Cleaner then click on Rescan, the table will be populated (see screenshot)

Do you have SeLinux or AppArmor enabled? Oh, crap. I see the issue. That's very odd. Need to research.

This is fixed now. You can test and when you have verified it's working, simply close.
