From 2d13f296e28f44c2e06aebec1c6aecf14b3fc96c Mon Sep 17 00:00:00 2001 From: Michael J Gruber Date: Thu, 31 Mar 2011 11:08:57 +0200 Subject: [PATCH] builtin/show: do not prune by pathspec By design, "git show commit -- path" is not "git show commit:path", and there is no reason to change that. But "git show commit -- path" simply returns nothing at all "most of the time" because it prunes by pathspec even though it does not walk commits. This is pretty useless. So, turn off commit pruning (but keep diff limiting of course) so that "git show commit -- path" shows the commit message and the diff that the commit introduces to path (filtered by path); only the diff will be empty "most of the time". As an intended side effect, users mistaking "git show commit -- path" for "git show commit:path" are automatically reminded that they asked git to show a commit, not a blob. In case the user has specified "--do-walk", assume they want the old behaviour (prune by default). --- builtin/log.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/builtin/log.c b/builtin/log.c index 36769bab3b69a9..d376aea3d493b4 100644 --- a/builtin/log.c +++ b/builtin/log.c @@ -789,6 +789,8 @@ int cmd_show(int argc, const char **argv, const char *prefix) opt.def = "HEAD"; opt.tweak = show_setup_revisions_tweak; cmd_log_init(argc, argv, prefix, &rev, &opt, &cfg); + if (rev.no_walk) + rev.prune = 0; if (!rev.no_walk) { ret = cmd_log_walk(&rev);
