197: .git internals with Gordon 🔧

OK, If you really want to know how git works, this is the episode for you.

KG talks with his longtime colleague and mentor Gordon McCreight. Gordon is a

wiz in general but his knowledge of git goes deep. So in this episode, KG goes

solo and really dives in-depth about how git works.

Buckle up and listen on; you'll come out on the outer side with a much

sounder understanding of git-scm.com.

• git gc vs
prune (alblue.bandlem.com/2011/11/git-tip-of-week-gc-…)

Objects which are no longer referenced can be evicted with git prune; though this is a low-level operation which is often called from git gc. By default it will not remove commits newer than 2 weeks old, and of course the commits that are reachable from that; so provided the branch (or tag) deleted has recent commits, it will stay around in the git repository for up two a fortnight afterwards.
