The current behavior is to return NULL when strbuf did not
actually allocate a string. This can be quite surprising to
callers, though, who may feed the strbuf from arbitrary data
and expect to always get a valid value.
In most cases, it does not make a difference because calling
any strbuf function will cause an allocation (even if the
function ends up not inserting any data). But if the code is
structured like:
struct strbuf buf = STRBUF_INIT;
if (some_condition)
strbuf_addstr(&buf, some_string);
return strbuf_detach(&buf, NULL);
then you may or may not return NULL, depending on the
condition. This can cause us to segfault in http-push
(when fed an empty URL) and in http-backend (when an empty
parameter like "foo=bar&&" is in the $QUERY_STRING).
This patch forces strbuf_detach to allocate an empty
NUL-terminated string when it is called on a strbuf that has
not been allocated.
I investigated all call-sites of strbuf_detach. The majority
are either not affected by the change (because they call a
strbuf_* function unconditionally), or can handle the empty
string just as easily as NULL.

When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.
At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.
So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.
The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

From the FILES section of the git-config(1) manual:
$GIT_DIR/config::
Repository specific configuration file. (The filename is
of course relative to the repository root, not the working
directory.)
That's confusing because $GIT_DIR really is relative to the working
directory.
$ GIT_DIR=.git GIT_EDITOR='pwd; echo editing'
$ export GIT_DIR GIT_EDITOR
$ git config --edit --local
/home/jrn/src/git/Documentation
editing .git/config
It turns out that the comment is a remnant from older days when the
heading said ".git/config" (which is indeed relative to the top of the
worktree).
It was only when the heading was changed to refer more precisely to
<git dir>/config (see v1.5.3.2~18, AsciiDoc tweak to avoid leading
dot, 2007-09-14) that the parenthesis stopped making sense. Remove

If stderr isn't a tty, we shouldn't be printing incremental progress

but that wouldn't allow things like 'git push --progress' to force progress
reporting to on, so I won't try to solve the general case right now.

The default compiler and cflags were mostly "works for me"
when I built the original version. We need to be much less
careful here than usual, because we know we are building
only on OS X. But it's only polite to at least respect the
CFLAGS and CC definitions that the user may have provided
earlier.
While we're at it, let's update our definitions and rules to
be more like the top-level Makefile; default our CFLAGS to
include -O2, and make sure we use CFLAGS and LDFLAGS when
linking.

If a commit object has a header line at the end of the
buffer that is missing its newline (or if it appears so
because the content on the header line contains a stray
NUL), then git will segfault.
Interestingly, this case is explicitly handled and we do
correctly scan the final line for the header we are looking
for. But if we don't find it, we will dereference NULL while
trying to look at the next line.
Git will never generate such a commit, but it's good to be
defensive. We could die() in such a case, but since it's
easy enough to handle it gracefully, let's just issue a
warning and continue (so you could still view such a commit
with "git show", though you might be missing headers after
the NUL).

When we parse the name and email from a commit to
pretty-print them, we usually can just put the result
directly into our strbuf result. However, if we are going to
use the mailmap, then we must first copy them into a
NUL-terminated buffer to feed to the mailmap machinery.
We did so by using strlcpy into a static buffer, but we used
it wrong. We fed it the length of the substring we wanted to
copy, but never checked that that length was less than the
size of the destination buffer.
The simplest fix is to just use snprintf to copy the
substring properly while still respecting the destination
buffer's size. It might seem like replacing the static
buffer with a strbuf would help, but we need to feed a
static buffer to the mailmap machinery anyway, so there's
not much benefit to handling arbitrary sizes.
A more ideal solution would be for mailmap to grow an
interface that:
1. Takes a pointer and length combination, instead of
assuming a NUL-terminated string.
2. Returns a pointer to the mailmap's allocated string,
rather than copying it into the buffer.
Then we could avoid the need for an extra buffer entirely.
However, doing this would involve a lot of refactoring of
mailmap and of string_list (which mailmap uses to store the
map itself). For now, let's do the simplest thing to fix the
bug.

When reading patterns from a file, we pass the lines as allocated string
buffers to append_grep_pat() and never free them. That's not a problem
because they are needed until the program ends anyway.
However, now that the function duplicates the pattern string, we can
reuse the strbuf after calling that function. This simplifies the code
a bit and plugs a minor memory leak.

Currently, patterns that contain newline characters don't match anything
when given to git grep. Regular grep(1) interprets patterns as lists of
newline separated search strings instead.
Implement this functionality by creating and inserting extra grep_pat
structures for patterns consisting of multiple lines when appending to
the pattern lists. For simplicity, all pattern strings are duplicated.
The original pattern is truncated in place to make it contain only the

Commit 875b91b (diff --no-index: use strbuf for temporary pathnames,
2012-04-25) introduced a regression when using diff --no-index with
directories. When iterating through a directory, the switch to strbuf
from heap-allocated char arrays caused paths to form like 'dir/file1',
'dir/file1file2', rather than 'dir/file1', 'dir/file2' as expected.
Avoid this by resetting the paths variables to their original length
before each iteration.
