From 0b38227f283e208866d3e2ac85bcd947a71f1b17 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 12 Nov 2008 03:25:52 -0500 Subject: [PATCH] commit: Fix stripping of patch in verbose mode. When the "-v" option is given, we put diff of what is to be committed into the commit template, and then strip it back out again after the user has edited it. We used to look for the diff by searching for the "diff --git a/" header. With diff.mnemonicprefix set in the configuration, however, this pattern does not match. The pattern is loosened to cover this case. Also, if the user puts their own diff in the message (e.g., as a sample output), then we will accidentally trigger the pattern, removing part of their output. We can avoid doing this stripping altogether if the user didn't use "-v" in the first place, so we know that any match we find will be a false positive. [jc: this fix was split out of a series originally meant for master.] Signed-off-by: Jeff King Signed-off-by: Junio C Hamano --- builtin-commit.c | 8 +++-- t/t7507-commit-verbose.sh | 73 +++++++++++++++++++++++++++++++++++++++ 2 files changed, 78 insertions(+), 3 deletions(-) create mode 100755 t/t7507-commit-verbose.sh diff --git a/builtin-commit.c b/builtin-commit.c index b563a0d67c..1e08399919 100644 --- a/builtin-commit.c +++ b/builtin-commit.c @@ -1004,9 +1004,11 @@ int cmd_commit(int argc, const char **argv, const char *prefix) } /* Truncate the message just before the diff, if any. */ - p = strstr(sb.buf, "\ndiff --git a/"); - if (p != NULL) - strbuf_setlen(&sb, p - sb.buf + 1); + if (verbose) { + p = strstr(sb.buf, "\ndiff --git "); + if (p != NULL) + strbuf_setlen(&sb, p - sb.buf + 1); + } if (cleanup_mode != CLEANUP_NONE) stripspace(&sb, cleanup_mode == CLEANUP_ALL); diff --git a/t/t7507-commit-verbose.sh b/t/t7507-commit-verbose.sh new file mode 100755 index 0000000000..519adba80b --- /dev/null +++ b/t/t7507-commit-verbose.sh @@ -0,0 +1,73 @@ +#!/bin/sh + +test_description='verbose commit template' +. ./test-lib.sh + +cat >check-for-diff <message <<'EOF' +subject + +body +EOF + +test_expect_success 'setup' ' + echo content >file && + git add file && + git commit -F message +' + +test_expect_failure 'initial commit shows verbose diff' ' + git commit --amend -v +' + +test_expect_success 'second commit' ' + echo content modified >file && + git add file && + git commit -F message +' + +check_message() { + git log -1 --pretty=format:%s%n%n%b >actual && + test_cmp "$1" actual +} + +test_expect_success 'verbose diff is stripped out' ' + git commit --amend -v && + check_message message +' + +test_expect_success 'verbose diff is stripped out (mnemonicprefix)' ' + git config diff.mnemonicprefix true && + git commit --amend -v && + check_message message +' + +cat >diff <<'EOF' +This is an example commit message that contains a diff. + +diff --git c/file i/file +new file mode 100644 +index 0000000..f95c11d +--- /dev/null ++++ i/file +@@ -0,0 +1 @@ ++this is some content +EOF + +test_expect_success 'diff in message is retained without -v' ' + git commit --amend -F diff && + check_message diff +' + +test_expect_failure 'diff in message is retained with -v' ' + git commit --amend -F diff -v && + check_message diff +' + +test_done
