2009-11-20git am/mailinfo: Don't look at in-body headers when rebasingLibravatar Lukas Sandström1-1/+11
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.

2009-07-15Revert "mailinfo: Remove only one set of square brackets"Libravatar Junio C Hamano1-7/+0
This reverts commit 650d30d8a120c8982309ccb9ef40432b4ea2eb74. Some mailing lists are configured add prefix "[listname] " to all their messages, and also people hand-edit subject lines, be it an output from format-patch or a patch generated by some other means. We cannot stop people from mucking with the subject line, and with the change, there always will be need for hand editing the subject when that happens. People have depended on the leading [bracketed string] removal.

* ae/maint-mailinfo-rm-only-one-patch-marker: mailinfo: Remove only one set of square brackets
2009-07-08mailinfo: Remove only one set of square bracketsLibravatar Andreas Ericsson1-0/+7
git-format-patch prepends patches with a [PATCH x/n] prefix, but mailinfo used to remove any number of square-bracket pairs and the content between them. This prevents one from using a commit subject like this: [ and ] must be allowed as input Removing the square bracket pair from this rather clumsily constructed subject line loses important information, so we must take care not to. This patch causes the subject stripping to stop after it has encountered one pair of square brackets. One possible downside of this patch is that the patch-handling programs will now fail at removing author-added square-brackets to be removed, such as [RFC][PATCH x/n] However, since format-patch only adds one set of square brackets, this behaviour is quite easily undesrstood and defended while the previous behaviour is not.

2009-05-18builtin-mailinfo.c: compare character encodings case insensitivelyLibravatar Brandon Casey1-4/+2
When converting between character encodings, git tests whether the "from" encoding and the "to" encoding have the same name. git should perform this test case insensitively so that e.g. utf-8 is not seen as a different encoding than UTF-8. Additionally, it is not necessary to call tolower() anymore on the encodings extracted from the mail message.

2009-01-10mailinfo: correctly handle multiline 'Subject:' headerLibravatar Kirill Smelkov1-8/+19
When native language (RU) is in use, subject header usually contains several parts, e.g. Subject: [Navy-patches] [PATCH] =?utf-8?b?0JjQt9C80LXQvdGR0L0g0YHQv9C40YHQvtC6INC/0LA=?= =?utf-8?b?0LrQtdGC0L7QsiDQvdC10L7QsdGF0L7QtNC40LzRi9GFINC00LvRjyA=?= =?utf-8?b?0YHQsdC+0YDQutC4?= This exposes several bugs in builtin-mailinfo.c: 1. decode_b_segment: do not append explicit NUL -- explicit NUL was preventing correct header construction on parts concatenation via strbuf_addbuf in decode_header_bq.

2008-08-19mailinfo: avoid violating strbuf assertionLibravatar Jeff King1-1/+1
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.

2008-08-18mailinfo: re-fix MIME multipart boundary parsingLibravatar Don Zickus1-3/+3
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.

2008-08-09mailinfo: fix MIME multi-part message boundary handlingLibravatar Junio C Hamano1-6/+11
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.

2008-07-06mailinfo: feed the correct line length to decode_transfer_encoding()Libravatar Junio C Hamano1-0/+1
When handling a MIME multipart message, multi-part boundary lines are eaten by a call to handle_boundary() function from the main loop of handle_body(), and after that happens, we should update the line length correctly, because handle_boundary() udpates line[] with new data.

This makes rebase/am keep the original commit log message better, even when it does not conform to "single line paragraph to say what it does, then explain and defend why it is a good change in later paragraphs" convention. This change is a two-edged sword. While the earlier behaviour would make such commit log messages more friendly to readers who expect to get the birds-eye view with oneline summary formats, users who primarily use git as a way to interact with foreign SCM systems would not care much about the convenience of oneline git log tools, but care more about preserving their own convention. This changes their commits less useful to readers who read them with git tools while keeping them more consistent with the foreign SCM systems they interact with.

2007-07-18Do a better job at guessing unknown character setsLibravatar Linus Torvalds1-4/+29
At least in the kernel development community, we're generally slowly converting to UTF-8 everywhere, and the old default of Latin1 in emails is being supplanted by UTF-8, and it doesn't necessarily show up as such in the mail headers (because, quite frankly, when people send patches around, they want the email client to do as little as humanly possible about the patch) Despite that, it's often the case that email addresses etc still have Latin1, so I've seen emails where this is a mixed bag, with Signed-off parts being copied from email (and containing Latin1 characters), and the rest of the email being a patch in UTF-8. So this suggests a very natural change: if the target character set is utf-8 (the default), and if the source already looks like utf-8, just assume that it doesn't need any conversion at all. Only assume that it needs conversion if it isn't already valid utf-8, in which case we (for historical reasons) will assume it's Latin1. Basically no really _valid_ latin1 will ever look like utf-8, so while this changes our historical behaviour, it doesn't do so in practice, and makes the default behaviour saner for the case where the input was already in proper format. We could do a more fancy guess, of course, but this correctly handled a series of patches I just got from Andrew that had a mixture of Latin1 and UTF-8 (in different emails, but without any character set indication).

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).

2007-03-07General const correctness fixesLibravatar Shawn O. Pearce1-3/+3
We shouldn't attempt to assign constant strings into char*, as the string is not writable at runtime. Likewise we should always be treating unsigned values as unsigned values, not as signed values. Most of these are very straightforward. The only exception is the (unnecessary) xstrdup/free in builtin-branch.c for the detached head case. Since this is a user-level interactive type program and that particular code path is executed no more than once, I feel that the extra xstrdup call is well worth the easy elimination of this warning.
