> Deletion of old archived logs on rolling failes for index > 99.
> We have a process which logs much, which results in more than 99 log files per day (config below), e.g.
> snowball_POLL_MSG_SRV_xdebug-old-2011-09-13.110.log.zip.
> On rolling event, only the first 99 were deleted, due to bug in
> FileNamePattern::toRegex for index (Integer):
> regEx: \d{1,2)
> which means digits with max length of 2.
> We need at least 3 digits:
> regEx: \d{1,3)
> better 4? ;-)
> Workarounds like increasing file size, or hourly-rollover to hold index lower than 100 are not very wellcomed.
> Thanks in advance,
> Dieter Mueller.
