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.]

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.

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).

This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily. Leftover from this will be fixed in a separate step, including
idiotic conversions like
if (!strncmp("foo", arg, 3))
=>
if (!(-prefixcmp(arg, "foo")))
This was done by using this script in px.perl
#!/usr/bin/perl -i.bak -p
if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
}
if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
}
and running:
$ git grep -l strncmp -- '*.c' | xargs perl px.perl

It is plausible for somebody to want to view the commit log in a
different encoding from i18n.commitencoding -- the project's
policy may be UTF-8 and the user may be using a commit message
hook to run iconv to conform to that policy (and either not have
i18n.commitencoding to default to UTF-8 or have it explicitly
set to UTF-8). Even then, Latin-1 may be more convenient for
the usual pager and the terminal the user uses.
The new variable i18n.logoutputencoding is used in preference to
i18n.commitencoding to decide what encoding to recode the log
output in when git-log and friends formats the commit log message.

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

When the input mbox does not identify what encoding it is in,
and already have RFC2047 stripped away, we cannot tell what
encoding the header text is in. For body text, when the message
does not say what charset it is in, we fall back to assume
latin-1 input when converting to utf8. This should be done
consistently to the header as well.

We exited prematurely from header parsing loop when the header
field did not have a space after the colon but we insisted on
it, and we got the check wrong because we forgot that we strip
the trailing whitespace before we do the check.
The space after the colon is not even required by RFC2822, so
stop requiring it. While we are at it, the header line is
specified to be more strict than "anything with a colon in it"
(there must be one or more characters before the colon, and they
must not be controls, SP or non US-ASCII), so implement that
check as well, lest we mistakenly think something like:
Bogus not a header line: this is not.

- Move handle_info into main so it is called once
after everything has been parsed. This allows the removal
of a static variable and removes two duplicate calls.
- Move parsing of inbody headers into handle_commit.
This means we parse the in-body headers after we have decoded
the character set, and it removes code duplication between
handle_multipart_one_part and handle_body.
- Change the flag indicating that we have seen an in body
prefix header into another bit in seen.
This is a little more general and allows the possibility of parsing
in body headers after the body message has begun.

- A new header file, git-compat-util.h, is introduced. This
looks at various NO_XXX and does necessary function name
replacements, equivalent of -Dstrcasestr=gitstrcasestr in the
Makefile.
- Those function name replacements are removed from the Makefile.
- Common features such as usage(), die(), xmalloc() are moved
from cache.h to git-compat-util.h; cache.h includes

When the message body does not identify what encoding it is in,

This attempts to minimally cope with a subset of MIME "features" often
seen in patches sent to our mailing lists. Namely:
- People's name spelled in characters outside ASCII (both on From:
header and the signed-off-by line).
- Content-transfer-encoding using quoted-printable (both in
multipart and non-multipart messages).
These MIME features are detected and decoded by "git mailinfo".
Optionally, with the '-u' flag, the output to .info and .msg is
transliterated from its original chaset to utf-8. This is to
encourage people to use utf8 in their commit messages for
interoperability.
Applymbox accepts additional flag '-u' which is passed to mailinfo.

Some people split their long E-mail address over two lines
using the RFC2822 header "folding". We can lose authorship
information this way, so make a minimum effort to deal with it,
instead of special casing only the "Subject:" field.
We could teach mailsplit to unfold the folded header, but
teaching mailinfo about folding would make more sense; a single

- avoid duplicating [PATCH] in the commit message body if the
original commit has it already (happens for commits done from
mails via applymbox).
- check if the commit author is different from the one who is
running the script, and emit an appropriate "From:" and
"Date: " lines to the output.
- with '--date', emit "Date: " line to preserve the original
author date even for the user's own commit.
- teach mailinfo to grok not just "From: " but "Date: ".
The patch e-mail output by format-patch starts with the first
line from the original commit message, prefixed with [PATCH],
and optionally a From: line if you are reformatting a patch
obtained from somebody else, a Date: line from the original
commit if (1) --date is specified or (2) for somebody else's
patch, and the rest of the commit message body.
Expected use of this is to move the title line from the commit
to Subject: when sending it via an e-mail, and leave the From:
and the Date: lines as the first lines of your message.
The mailinfo command has been changed to read Date: (in addition
to From: it already understands) and do sensible things when
running applymbox.

Rename into a "tools" subdirectory, and change name of "dotest" to "applymbox".
Remove stripspace (which was already copied into git) and cvs2git (which

I guess.
This way we don't get it in the commit message, even if the patch had
been generated by cogito (or CVS, ugh) and people didn't add the proper
"---" marker.
..and git-apply does a lot better job at it anyway.
Also, we break the comment/diff on a line that starts with "diff -", not
just on the "---" line. Especially for git diffs, we actually want that
line in the diff.
(We should probably also break on "Index: ..." followed by "=====")
Now that git does pretty reliable date parsing, we might as well get
the date from the email itself. Of course, it's still questionable
whether the date on the email is all that relevant, but it's certainly
no worse than taking the commit date.
I looked a bit at my old BK tools for the same thing, but they were
just so horrid in many ways that I largely rewrote it all and these
tools do things a bit differently. Instead of aggressively piping
data from one process to another (which was clever but very hard
to follow), this first just splits out the mbox into many smaller
email files, and then does some scripts on these temporary files.
