I’m used to it > being 11 for this project? It's not a fixed size. Long ago, the rule was "enough to be unique, but at least 7 (or whatever you set core.abbrev to)". These days that "7" is scaled based on the number of objects in the repo. See e6c587c733 (abbrev: auto size the default abbreviation, 2016-09-30). So I'd expect 10 digits in a fresh clone of git.git. It's possible Junio has set core.abbrev to something fixed, though. > Does the age of the commit matter? Nope, it shouldn't. -Peff
