Hi DV,
Hi Jim !
I ran this on a fresh clone of libvirt:
$ du -sh .git; git gc --aggressive; du -sh .git
54M .git
...
45M .git
I propose to do the same thing on the server, libvirt.org.
It's not a big deal, but decreased bandwidth wouldn't hurt,
and the slightly smaller on-disk repository makes even local
git tools feel a little snappier. It's worth doing for all git
repositories.
As far as I know, no one stores anything useful as "unlinked" commits
on the server (they would be removed by the above), so there is no
down-side to doing this. In fact, "man git-gc" recommends to run
git gc --aggressive "every few hundred changesets or so".
Adding a cron job to do it every few weeks would be nice (e.g., Sunday
at 4am local). Let me know and I'll do it via my account.
Hum, I already have something similar running:
xmlsoft:~ -> cat bin/GitMaintainance
#!/bin/sh
# Garbage collect the libvirt GIT repository
git --git-dir /git/libvirt.git gc > $HOME/tmp/GitMaintainance.log 2>&1
xmlsoft:~ -> crontab -l | grep GitMaintainance
4 4 * * Sun /u/veillard/bin/GitMaintainance
xmlsoft:~ ->
Seems to have run normally on Sun 9 Jan from what I can tell :-)
So basically I should just add --aggressive to the garbage collection
command for extra cleanup, right ?
