What Makes save.dat File Grow? There A "Prune" App For It?

[jimwg]

Happy New Year All!

In exploring Porteus I was happy to learn that unlike Puppy that you can actually open up and do surgery on a save.dat and maybe shrink it so. I'd like to know exactly piles up in a save.dat file to make it grow? I know that if I use zero cache in SeaMonkey browser and delete any junk or unneeded files in SeaMonkey Mail that it keeps the save.dat file size more or less down (and I hope to learn to use shortcut or alias files so that SeaMonkey Maile's main files reside in my /mnt/sdb1/Copy/Documents/ folder if possible). My main question is, is there a way to tell what other files are making save.dat swell so I could once a while prune them out? My logic says if there was a way to tell by date stamp which files were added since installation that it'd make this process far easier but there's no Catfish-style file manager in Porteus to do such so far.

Any hints much appreciated!

Happy New Year to you also Jim.

My save.dat file is 128MB and I watch it's size by doing these steps (from my Notes file):

Code: Select all

# View space usage of porteussave.dat file
** With changes= cheatcode not used
 su
 toor
 mloop  /mnt/sda6/porteussave.dat
 du -sh /mnt/loop     # Show the amount used   - OR -
 df -h  /mnt/loop     # Show filesystem summary
 uloop                # unmount the loop
   http://forum.porteus.org/viewtopic.php?f=81&t=1941&start=15#p13272

While I haven't tried it I believe with the dat file mounted you could explore it's contents with SpaceFM.

In that it's a reflection of your live system I believe deleing files from your live system will result in them being deleted from the save.dat file also.

Another thing that I do, once my system is configured the way that I want with signons, bookmarks, apps and scripts, I make a backup copy of the save.dat file, and if things get out of hand I restore from the backup.

Something that does grow in the save.dat file are log files. And there are several that retain everything since the 1st boot of Porteus. Look here for more info. /mnt/live/memory/changes/var/log

@Ed_P
could you show me output of 'ls -al /var/log' command please and i may find a cure for this.

This list shows a whole lot more files than SpaceFM's view of /mnt/live/memory/changes/var/log.

The logs I was referring to have entries like this cron file:

Something that deletes entries after 7 days would be useful IMO.

Something that deletes entries after 7 days would be useful IMO.

we have it - it's called logrotate:
https://wiki.archlinux.org/index.php/Logrotate
for some reason it does not work - maybe due to cron perms issues mentioned in Arch wiki. could you edit /etc/logrotate.conf and unhash 'compress' option then run as root:

Code: Select all

logrotate /etc/logrotate.conf

once you do it please show me output of 'ls -al /var/log' again.
thanks

so must be something with logrotate rules. will dig into this - thanks for help.

EDIT:
ok got it - please edit /etc/logrotate.d/syslog as follows:

Code: Select all

/var/log/cron /var/log/debug /var/log/maillog /var/log/messages /var/log/secure /var/log/spooler /var/log/syslog {
    rotate 1
    size 500k
    compress
    sharedscripts
    postrotate
	/bin/kill -HUP `cat /var/run/syslogd.pid 2>/dev/null` 2>/dev/null || true
    endscript
}

this will compress and rotate once all main logs if they reach 500KB in size. this rule will be added to next release.
please wait a day to check if cron will do the job for /var/log/messages, etc..

please run 'logrotate /etc/logrotate.conf' manually and check if the job is done.

It's certainly doing something.

So what happens to the .1.gz files?

Should the wtmp file be added to /etc/logrotate.d/syslog file?

[fanthom]

So what happens to the .1.gz files?
it gets overwritten by new log during next cron run if log specification matches the rules (over 500 KB in size in this case).

Should the wtmp file be added to /etc/logrotate.d/syslog file?
probably - will add it along with /var/log/btmp

found what's wrong with cron: it's daily job is set to run on 4:40 in the morning
will change that to some normal hour like 19.30 so it will actually have a chance to run and do the job.

I recommend it run when booting also. Or when shutting down.
