auto gc

auto gc

[Jens Axboe]

Hi,

I've noticed that recent git versions, in a supposedly helpful fashion,
run garbage collection automatically after a pull if it deems it
necessary:

[...]
Resolving 556 deltas...
 100% (556/556) done
Updating 9418d5d..99fee6d
Fast forward
Packing your repository for optimum performance. You may also
run "git gc" manually. See "git help gc" for more information.
Generating pack...
[...]

This is extremely annoying behaviour! If I'm on battery or just in a bit
of a hurry, I defeinitely don't want git second guessing me and deciding
that it's time to run git gc.

I'd suggest just printing a hint that running git gc would increase
performance, doing it automatically is definitely bad style (even more
so when then yet again changed git refs layout even breaks old scripts,
when git gc has run).

Set the following and it won't run automatically anymore for you:

	git config --global gc.auto 0
	git config --global gc.autopacklimit 0

More recently this message has been changed to:

  Packing your repository for optimum performance. You may also
  run "git gc" manually. See "git help gc" for more information.

The two options noted above are described in the manual for git-gc.

Great, that's a lot more appropriate in my opinion. I'll just update to
a later git.

Thanks!
