Question

In the past, one had to invoke git gc from time to time. I’ve read now, that latest Git versions should perform the cleanup automatically. Is this correct?

Answer 1

To an extent…

From the documentation at http://www.kernel.org/pub/software/scm/git/docs/git-gc.html

Pertaining to git gc –auto….

With this option, git gc checks whether any housekeeping is required;
if not, it exits without performing any work. Some git commands run
git gc –auto after performing operations that could create many loose
objects.

So it depends on the commands you are running.
