From 6d79cd8474b7bb4979f2a7544fd736bed190261a Mon Sep 17 00:00:00 2001 From: Kousik Sanagavarapu Date: Sat, 2 Sep 2023 14:30:39 +0530 Subject: [PATCH] ref-filter: sort numerically when ":size" is used Atoms like "raw" and "contents" have a ":size" option which can be used to know the size of the data. Since these atoms have the cmp_type FIELD_STR, they are sorted alphabetically from 'a' to 'z' and '0' to '9'. Meaning, even when the ":size" option is used and what we ultimatlely have is numbers, we still sort alphabetically. For example, consider the the following case in a repo refname contents:size raw:size ======= ============= ======== refs/heads/branch1 1130 1210 refs/heads/master 300 410 refs/tags/v1.0 140 260 Sorting with "--format="%(refname) %(contents:size) --sort=contents:size" would give refs/heads/branch1 1130 refs/tags/v1.0.0 140 refs/heads/master 300 which is an alphabetic sort, while what one might really expect is refs/tags/v1.0.0 140 refs/heads/master 300 refs/heads/branch1 1130 which is a numeric sort (that is, a "$ sort -n file" as opposed to a "$ sort file", where "file" contains only the "contents:size" or "raw:size" info, each of which is on a newline). Same is the case with "--sort=raw:size". So, sort numerically whenever the sort is done with "contents:size" or "raw:size" and do it the normal alphabetic way when "contents" or "raw" are used with some other option (they are FIELD_STR anyways).
