From: Junio C Hamano Date: Sun, 22 Jul 2012 20:01:22 +0000 (-0700) Subject: Merge branch 'jc/refactor-diff-stdin' into maint X-Git-Tag: v1.7.11.3~7 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/106ef55f3a303435519ac60a043755286f9e47f8?ds=inline;hp=-c Merge branch 'jc/refactor-diff-stdin' into maint "git diff", "git status" and anything that internally uses the comparison machinery was utterly broken when the difference involved a file with "-" as its name. This was due to the way "git diff --no-index" was incorrectly bolted on to the system, making any comparison that involves a file "-" at the root level incorrectly read from the standard input. * jc/refactor-diff-stdin: diff-index.c: "git diff" has no need to read blob from the standard input diff-index.c: unify handling of command line paths diff-index.c: do not pretend paths are pathspecs --- 106ef55f3a303435519ac60a043755286f9e47f8 diff --combined diff-no-index.c index beec49b5ac,09656bca1d..7d805a06af --- a/diff-no-index.c +++ b/diff-no-index.c @@@ -32,6 -32,13 +32,13 @@@ static int read_directory(const char *p return 0;
