add logfile cleanup utility

[peterjanssens]

We would like to propose a logfile cleanup utility. This allows for periodic cleanup (manual or cron) of the application logfiles (log_....txt).

Exisiting GarbageCollection utility does not handle logs, and the current logger doesn't auto delete old files.
Size limitations causes some logfiles to spill over to the root /tmp, so that directory was added

dry run is the default mode for a standard expiration of 100 days.
days can be set to any integer >0.
mode can be set to delete for actual deletion and verbosity can be set to verbose/quiet/silent for the sake of cron logging.

It would be better if this did not rely upon shell_exec to function.

[peterjanssens]

what alternative(s) would you suggest ?
@Unlink($path); as in unused_media ??

[peterjanssens]

I swapped the shell_exec for unlink (with glob for filematching)

[collectiveaccess]

You could also use caGetDirectoryContentsAsList(), which is a helper defined in app/helpers/utilityHelpers.php

[peterjanssens]

that helper has no pattern matching option, so you would still have to loop 'all' files no ?
and combine both (logdir, /tmp)

[collectiveaccess]

Yes, you'd have to loop through the files. That's going to happen one way or another. Your choice if you want to leave it as-is. We use glob in other places. Nothing wrong with it.

[peterjanssens]

I'm ok with this version.

[peterjanssens]

that was not the proper way to handle the default (unpassed) parameters, fixed now
