I understand it that objects which are not reachable form the tip of current branches are subject for garbage-collecting in 30 days. For example, let's say we are in "master" branch and do "git reset --hard master~1". It makes the previous HEAD commit unreachable from "master" branch and it can be GCd in 30 days (?). My understanding can be wrong, of course. The manual explainst options like gc.reflogExpire and gc.reflogExpireUnreachable separately but does not draw the big picture how things work. http://www.kernel.org/pub/software/scm/git/docs/git-gc.html ``` ## Matthieu Moy, 2009-04-12 15:54 Subject: Re: how to squash commits Message-ID: URL: https://gitlist.dev/e/vpq1vrxvpel.fsf%40bauges.imag.fr In-Reply-To: <871vrxlw4h.fsf@iki.fi> ``` Teemu Likonen writes: > Let's add the Git mailing list to the Cc list if someone there wants to > comment.

I didn't read about gc.reflogExpireUnreachable carrefully enough. -- Matthieu ```
