2014-09-22mailinfo: work around -Wstring-plus-int warningLibravatar Eric Sunshine1-1/+2
The just-released Apple Xcode 6.0.1 has -Wstring-plus-int enabled by default which complains about pointer arithmetic applied to a string literal: builtin/mailinfo.c:303:24: warning: adding 'long' to a string does not append to the string return !memcmp(SAMPLE + (cp - line), cp, strlen(SAMPLE) ... ~~~~~~~^~~~~~~~~~~~~ Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-09-16mailinfo: make ">From" in-body header check more robustLibravatar Jeff King1-1/+16
Since commit 81c5cf7 (mailinfo: skip bogus UNIX From line inside body, 2006-05-21), we have treated lines like ">From" in the body as headers. This makes "git am" work for people who erroneously paste the whole output from format-patch: From 12345abcd...fedcba543210 Mon Sep 17 00:00:00 2001 From: them Subject: [PATCH] whatever into their email body (assuming that an mbox writer then quotes "From" as ">From", as otherwise we would actually mailsplit on the in-body line). However, this has false positives if somebody actually has a commit body that starts with "From "; in this case we erroneously remove the line entirely from the commit message. We can make this check more robust by making sure the line actually looks like a real mbox "From" line. Inspect the line that begins with ">From " a more carefully to only skip lines that match the expected pattern (note that the datestamp part of the format-patch output is designed to be kept constant to help those who write magic(5) entries).

Avoid running over the end of header string while parsing an incoming e-mail message to extract the patch. * rs/mailinfo-header-cmp: mailinfo: use strcmp() for string comparison
2014-06-02mailinfo: use strcmp() for string comparisonLibravatar René Scharfe1-3/+3
The array header is defined as: static const char *header[MAX_HDR_PARSED] = { "From","Subject","Date", }; When looking for the index of a specfic string in that array, simply use strcmp() instead of memcmp(). This avoids running over the end of the string (e.g. with memcmp("Subject", "From", 7)) and gets rid of magic string length constants.

2013-12-05replace {pre,suf}fixcmp() with {starts,ends}_with()Libravatar Christian Couder1-8/+8
Leaving only the function definitions and declarations so that any new topic in flight can still make use of the old functions, replace existing uses of the prefixcmp() and suffixcmp() with new API functions. The change can be recreated by mechanically applying this: $ git grep -l -e prefixcmp -e suffixcmp -- \*.c | grep -v strbuf\\.c | xargs perl -pi -e ' s|!prefixcmp\(|starts_with\(|g; s|prefixcmp\(|!starts_with\(|g; s|!suffixcmp\(|ends_with\(|g; s|suffixcmp\(|!ends_with\(|g; ' on the result of preparatory changes in this series.

2012-11-15Merge branch 'jc/same-encoding'Libravatar Junio C Hamano1-1/+2
Various codepaths checked if two encoding names are the same using ad-hoc code and some of them ended up asking iconv() to convert between "utf8" and "UTF-8". The former is not a valid way to spell the encoding name, but often people use it by mistake, and we equated them in some but not all codepaths. Introduce a new helper function to make these codepaths consistent. * jc/same-encoding: reencode_string(): introduce and use same_encoding() Conflicts: builtin/mailinfo.c
2012-11-04reencode_string(): introduce and use same_encoding()Libravatar Junio C Hamano1-1/+1
Callers of reencode_string() that re-encodes a string from one encoding to another all used ad-hoc way to bypass the case where the input and the output encodings are the same. Some did strcmp(), some did strcasecmp(), yet some others when converting to UTF-8 used is_encoding_utf8(). Introduce same_encoding() helper function to make these callers use the same logic. Notably, is_encoding_utf8() has a work-around for common misconfiguration to use "utf8" to name UTF-8 encoding, which does not match "UTF-8" hence strcasecmp() would not consider the same. Make use of it in this helper function. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-09-30mailinfo: don't require "text" mime type for attachmentsLibravatar Linus Torvalds1-11/+0
Currently "git am" does insane things if the mbox it is given contains attachments with a MIME type that aren't "text/*". In particular, it will still decode them, and pass them "one line at a time" to the mail body filter, but because it has determined that they aren't text (without actually looking at the contents, just at the mime type) the "line" will be the encoding line (eg 'base64') rather than a line of *content*. Which then will cause the text filtering to fail, because we won't correctly notice when the attachment text switches from the commit message to the actual patch. Resulting in a patch failure, even if patch may be a perfectly well-formed attachment, it's just that the message type may be (for example) "application/octet-stream" instead of "text/plain". Just remove all the bogus games with the message_type. The only difference that code creates is how the data is passed to the filter function (chunked per-pred-code line or per post-decode line), and that difference is *wrong*, since chunking things per pre-decode line can never be a sensible operation, and cannot possibly matter for binary data anyway. This code goes all the way back to March of 2007, in commit 87ab79923463 ("builtin-mailinfo.c infrastrcture changes"), and apparently Don used to pass random mbox contents to git. However, the pre-decode vs post-decode logic really shouldn't matter even for that case, and more importantly, "I fed git am crap" is not a valid reason to break *real* patch attachments. If somebody really cares, and determines that some attachment is binary data (by looking at the data, not the MIME-type), the whole attachment should be dismissed, rather than fed in random-sized chunks to "handle_filter()".

2012-09-25Merge branch 'jc/maint-mailinfo-mime-attr'Libravatar Junio C Hamano1-3/+2
When "git am" is fed an input that has multiple "Content-type: ..." header, it did not grok charset= attribute correctly. * jc/maint-mailinfo-mime-attr: mailinfo: do not concatenate charset= attribute values from mime headers
2012-09-17mailinfo: do not concatenate charset= attribute values from mime headersLibravatar Junio C Hamano1-3/+2
"Content-type: text/plain; charset=UTF-8" header should not appear twice in the input, but it is always better to gracefully deal with such a case. The current code concatenates the value to the values we have seen previously, producing nonsense such as "utf8UTF-8". Instead of concatenating, forget the previous value and use the last value we see. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-08-21commit/commit-tree: correct latin1 to utf-8Libravatar Linus Torvalds1-26/+2
When a line in the message is not a valid utf-8, "git mailinfo" attempts to convert it to utf-8 assuming the input is latin1 (and punt if it does not convert cleanly). Using the same heuristics in "git commit" and "git commit-tree" lets the editor output be in latin1 to make the overall system more consistent. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-01-16mailinfo: with -b, keep space after [foo]Libravatar Thomas Rast1-1/+10
The logic for the -b mode, where [PATCH] is dropped but [foo] is not, silently ate all spaces after the ]. Fix this by keeping the next isspace() character, if there is any. Being more thorough is pointless, as the later cleanup_space() call will normalize any sequence of whitespace to a single ' '.

2011-05-26mailinfo: always clean up rfc822 header foldingLibravatar Jeff King1-1/+1
Without the "-k" option, mailinfo will convert a folded subject header like: Subject: this is a subject that doesn't fit on one line into a single line. With "-k", however, we assumed that these newlines were significant and represented something that the sending side would want us to preserve. For messages created by format-patch, this assumption was broken by a1f6baa (format-patch: wrap long header lines, 2011-02-23). For messages sent by arbitrary MUAs, this was probably never a good assumption to make, as they may have been folding subjects in accordance with rfc822's line length recommendations all along. This patch now joins folded lines with a single whitespace character. This treats header folding purely as a syntactic feature of the transport mechanism, not as something that format-patch is trying to tell us about the original subject.

2010-05-31enums: omit trailing comma for portabilityLibravatar Gary V. Vaughan1-2/+2
Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
