Jeff King	e9d7d10a7f	mailinfo: avoid violating strbuf assertion In handle_from, we calculate the end boundary of a section to remove from a strbuf using strcspn like this: el = strcspn(buf, set_of_end_boundaries); strbuf_remove(&sb, start, el + 1); This works fine if "el" is the offset of the boundary character, meaning we remove up to and including that character. But if the end boundary didn't match (that is, we hit the end of the string as the boundary instead) then we want just "el". Asking for "el+1" caught an out-of-bounds assertion in the strbuf library. This manifested itself when we got a 'From' header that had just an email address with nothing else in it (the end of the string was the end of the address, rather than, e.g., a trailing '>' character), causing git-mailinfo to barf.

Don Zickus	289796dd29	mailinfo: re-fix MIME multipart boundary parsing Recent changes to is_multipart_boundary() caused git-mailinfo to segfault. The reason was after handling the end of the boundary the code tried to look for another boundary. Because the boundary list was empty, dereferencing the pointer to the top of the boundary caused the program to go boom. The fix is to check to see if the list is empty and if so go on its merry way instead of looking for another boundary. I also fixed a couple of increments and decrements that didn't look correct relating to content_top. The boundary test case was updated to catch future problems like this again.

Junio C Hamano	a9fd1383a7	mailinfo: fix MIME multi-part message boundary handling After finding a MIME multi-part message boundary line, the handle_body() function is supposed to first flush any accumulated contents from the previous part to the output stream. However, the code mistakenly output the boundary line it found. The old code that used one global, fixed-length buffer line[] used an alternate static buffer newline[] for keeping track of this accumulated contents and flushed newline[] upon seeing the boundary; when `3b6121f` (git-mailinfo: use strbuf's instead of fixed buffers, 2008-07-13) converted a fixed-length buffer in this program to use strbuf,these two buffers were converted to "line" and "prev" (the latter of which now has a much more sensible name) strbufs, but the code mistakenly flushed "line" (which contains the boundary we have just found), instead of "prev". This resulted in the first boundary to be output in front of the first line of the message. The rewritten implementation of handle_boundary() lost the terminating newline; this would then result in the second line of the message to be stuck with the first line. The is_multipart_boundary() was designed to catch both the internal boundary and the terminating one (the one with trailing "--"); this also was broken with the rewrite, and the code in the handle_boundary() to handle the terminating boundary was never triggered.

Lukas Sandström	e9fe804a82	git-mailinfo: Fix getting the subject from the in-body [PATCH] line "Subject: " isn't in the static array "header", and thus memcmp("Subject:", header[i], 7) will never match. Even if it did so, hdr_data[] may not have been allocated if there weren't a "Subject: " in-body when we process "[PATCH]" in the affected codepath.

Junio C Hamano	b2a42f55bc	t5100: Avoid filename "nul" There are broken filesystems that cannot have a file whose name is "nul" anywhere on it. Rename the test file to make ourselves more portable. Noticed by Mark Levedahl. Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago

Johannes Schindelin	cce8d6fdb4	mailsplit and mailinfo: gracefully handle NUL characters The function fgets() has a big problem with NUL characters: it reads them, but nobody will know if the NUL comes from the file stream, or was appended at the end of the line. So implement a custom read_line_with_nul() function. Noticed by Tommy Thorn.

Jay Soffian	87f1b8849b	mailinfo: feed only one line to handle_filter() for QP input The function is intended to be fed one logical line at a time to inspect, but a QP encoded raw input line can have more than one lines, just like BASE64 encoded one. Quoting LF as =0A may be unusual but RFC2045 allows it. The issue was noticed and fixed by Jay Soffian. JC added a test to protect the fix from regressing later.

Don Zickus	86747c132b	git-mailinfo fixes for patch munging Don't translate the patch to UTF-8, instead preserve the data as is. This also reverts a test case that was included in the original patch series. Also allow overwriting the authorship and title information we gather from RFC2822 mail headers with additional in-body headers, which was pointed out by Linus.

Don Zickus	87ab799234	builtin-mailinfo.c infrastrcture changes I am working on a project that required parsing through regular mboxes that didn't necessarily have patches embedded in them. I started by creating my own modified copy of git-am and working from there. Very quickly, I noticed git-mailinfo wasn't able to handle a big chunk of my email. After hacking up numerous solutions and running into more limitations, I decided it was just easier to rewrite a big chunk of it. The following patch has a bunch of fixes and features that I needed in order for me do what I wanted. Note: I'm didn't follow any email rfc papers but I don't think any of the changes I did required much knowledge (besides the boundary stuff). List of major changes/fixes: - can't create empty patch files fix - empty patch files don't fail, this failure will come inside git-am - multipart boundaries are now handled - only output inbody headers if a patch exists otherwise assume those headers are part of the reply and instead output the original headers - decode and filter base64 patches correctly - various other accidental fixes I believe I didn't break any existing functionality or compatibility (other than what I describe above, which is really only the empty patch file). I tested this through various mailing list archives and everything seemed to parse correctly (a couple thousand emails). [jc: squashed in another patch from Don's five patch series to fix the test case, as this patch exposes the bug in the test.] Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Linus Torvalds	34fc5cefa7	mailinfo: do not get confused with logical lines that are too long. It basically considers all the continuation lines to be lines of their own, and if the total line is bigger than what we can fit in it, we just truncate the result rather than stop in the middle and then get confused when we try to parse the "next" line (which is just the remainder of the first line).
