From d76650b8d16c9e5e7b6ee94e6922a3b99be74746 Mon Sep 17 00:00:00 2001 From: Brian Malehorn Date: Mon, 15 May 2017 23:06:49 -0700 Subject: interpret-trailers: honor the cut line If a commit message is edited with the "verbose" option, the buffer will have a cut line and diff after the log message, like so: my subject # ------------------------ >8 ------------------------ # Do not touch the line above. # Everything below will be removed. diff --git a/foo.txt b/foo.txt index 5716ca5..7601807 100644 --- a/foo.txt +++ b/foo.txt @@ -1 +1 @@ -bar +baz "git interpret-trailers" is unaware of the cut line, and assumes the trailer block would be at the end of the whole thing. This can easily be seen with: $ GIT_EDITOR='git interpret-trailers --in-place --trailer Acked-by:me' \ git commit --amend -v Teach "git interpret-trailers" to notice the cut-line and ignore the remainder of the input when looking for a place to add new trailer block. This makes it consistent with how "git commit -v -s" inserts a new Signed-off-by: line. This can be done by the same logic as the existing helper function, wt_status_truncate_message_at_cut_line(), uses, but it wants the caller to pass a strbuf to it. Because the function ignore_non_trailer() used by the command takes a pair, not a strbuf, steal the logic from wt_status_truncate_message_at_cut_line() to create a new wt_status_locate_end() helper function that takes pair, and make ignore_non_trailer() call it to help "interpret-trailers". Since there is only one caller of wt_status_truncate_message_at_cut_line() in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead and remove the old helper that no longer has any caller.
