From: Junio C Hamano Date: Fri, 29 Apr 2016 21:15:58 +0000 (-0700) Subject: Merge branch 'tb/blame-force-read-cache-to-workaround-safe-crlf' into maint X-Git-Tag: v2.8.2~5 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/002dd773b0b2ff2e28a335fb879a321056c0f6e2?hp=-c Merge branch 'tb/blame-force-read-cache-to-workaround-safe-crlf' into maint When running "git blame $path" with unnormalized data in the index for the path, the data in the working tree was blamed, even though "git add" would not have changed what is already in the index, due to "safe crlf" that disables the line-end conversion. It has been corrected. * tb/blame-force-read-cache-to-workaround-safe-crlf: correct blame for files commited with CRLF --- 002dd773b0b2ff2e28a335fb879a321056c0f6e2 diff --combined builtin/blame.c index e982fb8137,a5cabf79ea..21f42b0b62 --- a/builtin/blame.c +++ b/builtin/blame.c @@@ -6,7 -6,6 +6,7 @@@ */ #include "cache.h" +#include "refs.h" #include "builtin.h" #include "blob.h" #include "commit.h" @@@ -28,7 -27,6 +28,7 @@@ #include "line-range.h" #include "line-log.h" #include "dir.h" +#include "progress.h" static char blame_usage[] = N_("git blame [] [] [] [--] ");
