My experiments let me think it's "HEAD:FETCH_HEAD". Right? I came to this question after finding out that when I clone repos in bare mode then they don't have and explicit remote.<name>.fetch in their config. But a "git fetch" sometimes updated "something".

So it is really more like git fetch $remote HEAD This is what makes one-off bare-url pulls work, like: git pull git://... It runs fetch under the hood, which writes into FETCH_HEAD, and then we merge that. -Peff ^ permalink raw reply [flat|nested] 6+ messages in thread

Actually FETCH_HEAD consists of multiple lines, one per ref... but only top ref is merged. -- Jakub Narębski ^ permalink raw reply [flat|nested] 6+ messages in thread

Incorrect in that "only top" is misinformation, and irrelevant in the context of discussing the "what is fetched in a one-off fetch". ^ permalink raw reply [flat|nested] 6+ messages in thread

Then I'll teach JGit to fetch at least "HEAD" if nothing is configured and nothing explicitly specified as refspec.

Sounds like a sensible thing to do to match what JGit does to what we did from the time immemorial ;-) Thanks. ^ permalink raw reply [flat|nested] 6+ messages in thread
