Currently, the only colors available to --pretty=format
users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.
Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:
git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'
to emulate --pretty=oneline, or even

Commit notes are blobs which are shown together with the commit
message. These blobs are taken from the notes ref, which you can
configure by the config variable core.notesRef, which in turn can
be overridden by the environment variable GIT_NOTES_REF.
The notes ref is a branch which contains "files" whose names are
the names of the corresponding commits (i.e. the SHA-1).
The rationale for putting this information into a ref is this: we
want to be able to fetch and possibly union-merge the notes,
maybe even look at the date when a note was introduced, and we
want to store them efficiently together with the other objects.

Currently git-blame outputs text from the commit messages
(e.g. the author name and the summary string) as-is, without
even providing any information about the encoding used for
the data. It makes interpreting the data in multilingual
environment very difficult.
This commit changes the blame implementation to recode the
messages using the rules used by other commands like git-log.
Namely, the target encoding can be specified through the
i18n.commitEncoding or i18n.logOutputEncoding options, or
directly on the command line using the --encoding parameter.
Converting the encoding before output seems to be more
friendly to the porcelain tools than simply providing the
value of the encoding header, and does not require changing
the output format.
If anybody needs the old behavior, it is possible to
achieve it by specifying --encoding=none.

This attached patch introduces a single bit "use_terminator" in "struct
rev_info", which is normally false (i.e. most formats use separator
semantics) but by flipping it to true, you can ask for terminator
semantics just like oneline format does.
The function get_commit_format(), which is what parses "--pretty=" option,
now takes a pointer to "struct rev_info" and updates its commit_format and
use_terminator fields. It used to return the value of type "enum
cmit_fmt", but all the callers assigned it to rev->commit_format.
There are only two cases the code turns use_terminator on. Obviously, the
traditional oneline format (--pretty=oneline) is one of them, and the new
case is --pretty=tformat:... that acts like --pretty=format:... but flips
the bit on.
With this, "--pretty=tformat:%H %s" acts like --pretty=oneline.

Earlier, the callchain from pretty_print_commit() down to pp_title_line()
had an unwarranted assumption that the presense of "after_subject"
parameter, means the caller has already output MIME headers for
attachments. The parameter's primary purpose is to give extra header
lines the caller wants to place after pp_title_line() generates the
"Subject: " line.
This assumption does not hold when the user used the format.header
configuration variable to pass extra headers, and caused a message with
non-ASCII character to lack proper MIME headers (e.g. 8-bit CTE header).
The earlier logic also failed to suppress duplicated MIME headers when
"format-patch -s --attach" is asked for and the signer's name demanded
8-bit clean transport.
This patch fixes the logic by introducing a separate need_8bit_cte
parameter passed down the callchain. This can have one of these values:
-1 : we've already done MIME crap and we do not want to add extra header
to say this is 8bit in pp_title_line();
0 : we haven't done MIME and we have not seen anything that is 8bit yet;
1 : we haven't done MIME and we have seen something that is 8bit;
pp_title_line() must add MIME header.
It adds two tests by Jeff King who independently diagnosed this issue.

This change removes all obvious useless if-before-free tests.
E.g., it replaces code like this:
if (some_expression)
free (some_expression);
with the now-equivalent:
free (some_expression);
It is equivalent not just because POSIX has required free(NULL)
to work for a long time, but simply because it has worked for
so long that no reasonable porting target fails the test.
Here's some evidence from nearly 1.5 years ago:
http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html
FYI, the change below was prepared by running the following:
git ls-files -z | xargs -0 \
perl -0x3b -pi -e \
's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s'
Note however, that it doesn't handle brace-enclosed blocks like
"if (x) { free (x); }". But that's ok, since there were none like
that in git sources.
Beware: if you do use the above snippet, note that it can
produce syntactically invalid C code. That happens when the
affected "if"-statement has a matching "else".
E.g., it would transform this
if (x)
free (x);
else
foo ();
into this:
free (x);
else
foo ();
There were none of those here, either.
If you're interested in automating detection of the useless
tests, you might like the useless-if-before-free script in gnulib:
[it *does* detect brace-enclosed free statements, and has a --name=S
option to make it detect free-like functions with different names]

As Jeff King remarked, format strings with duplicate placeholders can
be slow to expand, because each instance is calculated anew.
This patch makes use of the fact that format_commit_message() and its
helper functions only ever add stuff to the end of the strbuf. For
certain expensive placeholders, store the offset and length of their
expansion with the strbuf at the first occurrence. Later they
expansion result can simply be copied from there -- no malloc() or
strdup() required.
These certain placeholders are the abbreviated commit, tree and
parent hashes, as the search for a unique abbreviated hash is quite
costly. Here are the times for next (best of three runs):
$ time git log --pretty=format:%h >/dev/null
real 0m0.611s
user 0m0.404s
sys 0m0.204s
$ time git log --pretty=format:%h%h%h%h >/dev/null

As Jeff King pointed out, some placeholder expansions are related to
each other: the steps to calculate one go most of the way towards
calculating the other, too.
This patch makes format_commit_message() parse the commit message
only once, remembering the position of each item. This speeds up
handling of format strings containing multiple placeholders from the
set %s, %a*, %c*, %e, %b.
Here are the timings for the git version in next. The first one is
to estimate the overhead of the caching, the second one is taken
from http://svn.tue.mpg.de/tentakel/trunk/tentakel/Makefile as an
example of a format string found in the wild. The times are the

Some of the --pretty=format placeholders expansions are expensive to
calculate. This is made worse by the current code's use of
interpolate(), which requires _all_ placeholders are to be prepared
up front.
One way to speed this up is to check which placeholders are present
in the format string and to prepare only the expansions that are
needed. That still leaves the allocation overhead of interpolate().
Another way is to use a callback based approach together with the
strbuf library to keep allocations to a minimum and avoid string
copies. That's what this patch does. It introduces a new strbuf
function, strbuf_expand().
The function takes a format string, list of placeholder strings,
a user supplied function 'fn', and an opaque pointer 'context'
to tell 'fn' what thingy to operate on.
The function 'fn' is expected to accept a strbuf, a parsed
placeholder string and the 'context' pointer, and append the
interpolated value for the 'context' thingy, according to the
format specified by the placeholder.

Before this patch, clear_commit_marks() recursed for each parent. This

the only reason that this did not lead to problems is the fact that we

For that purpose, the ->buf is always initialized with a char * buf living
in the strbuf module. It is made a char * so that we can sloppily accept

initializer for ->buf without making gcc unhappy for very good reasons.
strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf
anymore.
as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying
->buf isn't an option anymore, if ->buf is going to escape from the scope,
and eventually be free'd.
