From 73845048815bace98588df03ab76fa3e85fc0927 Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Sun, 7 Apr 2019 21:52:15 +0200 Subject: [PATCH] gc docs: note "gc --aggressive" in "fast-import" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Amend the "PACKFILE OPTIMIZATION" section in "fast-import" to explain that simply running "git gc --aggressive" after a "fast-import" should properly optimize the repository. This is simpler and more effective than the existing "repack" advice (which I'm keeping as it helps explain things) because it e.g. also packs the newly imported refs.

As noted in the "AGGRESSIVE" section in +linkgit:git-gc[1] the `--aggressive` option will find new deltas with +the `-f` option to linkgit:git-repack[1].
