From: René Scharfe Date: Thu, 21 Aug 2014 18:30:29 +0000 (+0200) Subject: sha1_name: avoid quadratic list insertion in handle_one_ref X-Git-Tag: v2.2.0-rc0~133^2~1 X-Git-Url: http://git.bitbasher.net/?a=commitdiff_plain;h=e8d1dfe639f71dc957c30c1eaa82a3ef0010cd8e;p=git.git sha1_name: avoid quadratic list insertion in handle_one_ref Similar to 16445242 (fetch-pack: avoid quadratic list insertion in mark_complete), sort only after all refs are collected instead of while inserting. The result is the same, but it's more efficient that way. The difference will only be measurable in repositories with a large number of refs.
