[p4] Old checkpoints and journal

[Albrecht, Matt]

I keep 8 previous versions around.  It probably shouldn't matter, but it
makes me feel a bit more comfortable because it can cover about a week's
worth of history in case something goes awry while I'm on vacation for a
week.  Old journal files are used by a script to keep our hot-backup
server in sync with the live version; by having the old versions around,
the script can restart on a hang-up where it last left off.

To remove old checkpoints and journal files, I use a simple bash script
in a daily cron-job that essentially just runs:

CHKPT_FILES_F="/tmp/$$.chkpt-files"
find $P4D_ARCHIVEDIR -follow -type f -iname 'backup.ckp.*.gz' -printf
'%p\n' | sort > $CHKPT_FILES_F
chkpt_filecount=$(cat $CHKPT_FILES_F | wc --lines)
if [ $chkpt_filecount -gt $MAX_ARCHIVED_FILES ]; then
    delcount=$(($chkpt_filecount - $MAX_ARCHIVED_FILES))
    for _I in $(head -n $delcount $CHKPT_FILES_F); do
        /bin/rm "$_I" > /dev/null
    done
fi

This ensures that there are always $MAX_ARCHIVED_FILES around, without
having to worry about if a nightly backup didn't create the checkpoint
files for some reason - that would be a different problem, and I
wouldn't want the clean-up script stomping over stuff just because of
the date.
