When we are rebasing we know that the header lines in the patch are good and that we don't need to pick up any headers from the body of the patch. This makes it possible to rebase commits whose commit message start with "From" or "Date". Test vectors by Jeff King.

Not much work, but I might have missed something. git-mailinfo usally breaks when I touch it, but the testsuite passes with this patch, including the extra test vectors from Jeff. The actual change is that mailinfo doesn't look for in-body headers at all if --no-inbody-headers is passed. git-am now passes this option to mailinfo when rebasing. This won't handle the case when a "bad" patch is passed to git-am from somewhere else than git rebase. /Lukas builtin-mailinfo.c | 5 +++++ git-am.sh | 13 ++++++++++--- t/t5100-mailinfo.sh | 6 +++++- t/t5100/info0015 | 5 +++++ t/t5100/info0015--no-inbody-headers | 5 +++++ t/t5100/info0016 | 5 +++++ t/t5100/info0016--no-inbody-headers | 5 +++++ t/t5100/msg0015 | 2 ++ t/t5100/msg0015--no-inbody-headers | 3 +++ t/t5100/msg0016 | 2 ++ t/t5100/msg0016--no-inbody-headers | 4 ++++ t/t5100/patch0015 | 8 ++++++++ t/t5100/patch0015--no-inbody-headers | 8 ++++++++ t/t5100/patch0016 | 8 ++++++++ t/t5100/patch0016--no-inbody-headers | 8 ++++++++ t/t5100/sample.mbox | 33 +++++++++++++++++++++++++++++++++ 16 files changed, 116 insertions(+), 4 deletions(-) create mode 100644 t/t5100/info0015 create mode 100644 t/t5100/info0015--no-inbody-headers create mode 100644 t/t5100/info0016 create mode 100644 t/t5100/info0016--no-inbody-headers create mode 100644 t/t5100/msg0015 create mode 100644 t/t5100/msg0015--no-inbody-headers create mode 100644 t/t5100/msg0016 create mode 100644 t/t5100/msg0016--no-inbody-headers create mode 100644 t/t5100/patch0015 create mode 100644 t/t5100/patch0015--no-inbody-headers create mode 100644 t/t5100/patch0016 create mode 100644 t/t5100/patch0016--no-inbody-headers diff --git a/builtin-mailinfo.c b/builtin-mailinfo.c index c90cd31..a81526e 100644 --- a/builtin-mailinfo.c +++ b/builtin-mailinfo.c @@ -26,6 +26,7 @@ static struct strbuf charset = STRBUF_INIT; static int patch_lines; static struct strbuf **p_hdr_data, **s_hdr_data; static int use_scissors; +static int use_inbody_headers = 1; #define MAX_HDR_PARSED 10 #define MAX_BOUNDARIES 5 @@ -771,6 +772,8 @@ static int handle_commit_msg(struct strbuf *line) return 0; if (still_looking) { + if (!use_inbody_headers) + still_looking = 0; strbuf_ltrim(line); if (!line->len) return 0; @@ -1033,6 +1036,8 @@ int cmd_mailinfo(int argc, const char **argv, const char *prefix) use_scissors = 1; else if (!strcmp(argv[1], "--no-scissors")) use_scissors = 0; + else if (!strcmp(argv[1], "--no-inbody-headers")) + use_inbody_headers = 0; else usage(mailinfo_usage); argc--; argv++; diff --git a/git-am.sh b/git-am.sh index c132f50..96869a2 100755 --- a/git-am.sh +++ b/git-am.sh @@ -289,7 +289,7 @@ split_patches () { prec=4 dotest="$GIT_DIR/rebase-apply" sign= utf8=t keep= skip= interactive= resolved= rebasing= abort= -resolvemsg= resume= scissors= +resolvemsg= resume= scissors= no_inbody_headers= git_apply_opt= committer_date_is_author_date= ignore_date= @@ -322,7 +322,7 @@ do --abort) abort=t ;; --rebasing) - rebasing=t threeway=t keep=t scissors=f ;; + rebasing=t threeway=t keep=t scissors=f no_inbody_headers=t ;; -d|--dotest) die "-d option is no longer supported.
