doc: discuss textconv versus external diff drivers

We already talk about how to use each one and how they work,
but it is a reasonable question to wonder why one might use
one over the other.

do not read beyond end of malloc'd buffer

With diff.suppress-blank-empty=true, "git diff --word-diff" would
output data that had been read from uninitialized heap memory.
The problem was that fn_out_consume did not account for the
possibility of a line with length 1, i.e., the empty context line
that diff.suppress-blank-empty=true converts from " \n" to "\n".
Since it assumed there would always be a prefix character (the space),
it decremented "len" unconditionally, thus passing len=0 to emit_line,
which would then blindly call emit_line_0 with len=-1 which would
pass that value on to fwrite as SIZE_MAX.  Boom.

add -i: ignore terminal escape sequences

On the author's terminal, the up-arrow input sequence is ^[[A, and
thus fat-fingering an up-arrow into 'git checkout -p' is quite
dangerous: git-add--interactive.perl will ignore the ^[ and [
characters and happily treat A as "discard everything".

As a band-aid fix, use Term::Cap to get all terminal capabilities.
Then use the heuristic that any capability value that starts with ^[
(i.e., \e in perl) must be a key input sequence.  Finally, given an
input that starts with ^[, read more characters until we have read a
full escape sequence, then return that to the caller.  We use a
timeout of 0.5 seconds on the subsequent reads to avoid getting stuck
if the user actually input a lone ^[.

Since none of the currently recognized keys start with ^[, the net

send-pack: avoid deadlock on git:// push with failed pack-objects

Commit 09c9957c fixes a deadlock in which pack-objects
fails, the remote end is still waiting for pack data, and we
are still waiting for the remote end to say something (see
that commit for a much more in-depth explanation).

We solved the problem there by making sure the output pipe
is closed on error; thus the remote sees EOF, and proceeds
to complain and close its end of the connection.

However, in the special case of push over git://, we don't
have a pipe, but rather a full-duplex socket, with another
dup()-ed descriptor in place of the second half of the pipe.
In this case, closing the second descriptor signals nothing
to the remote end, and we still deadlock.

This patch calls shutdown() explicitly to signal EOF to the
other side.

connect: treat generic proxy processes like ssh processes

The git_connect function returns two ends of a pipe for
talking with a remote, plus a struct child_process
representing the other end of the pipe. If we have a direct
socket connection, then this points to a special "no_fork"
child process.

The code path for doing git-over-pipes or git-over-ssh sets
up this child process to point to the child git command or
the ssh process. When we call finish_connect eventually, we
check wait() on the command and report its return value.

The code path for git://, on the other hand, always sets it
to no_fork. In the case of a direct TCP connection, this
makes sense; we have no child process. But in the case of a
proxy command (configured by core.gitproxy), we do have a
child process, but we throw away its pid, and therefore
ignore its return code.

Instead, let's keep that information in the proxy case, and
respect its return code, which can help catch some errors
(though depending on your proxy command, it will be errors
reported by the proxy command itself, and not propagated
from git commands. Still, it is probably better to propagate
such errors than to ignore them).

It also means that the child_process field can reliably be
used to determine whether the returned descriptors are
actually a full-duplex socket, which means we should be
using shutdown() instead of a simple close.

The way "object replacement" mechanism was tucked to the read_sha1_file()
interface was suboptimal in a couple of ways:

 - Callers that want it to die with useful diagnosis upon seeing a corrupt
   object does not have a way to say that they do not want any object

   does not use the replacement mechanism, and also it is a file scope
   static function that not many callers can call to begin with.

This adds a read_sha1_file_extended() that takes a set of flags; the
callers of read_sha1_file() passes a flag READ_SHA1_FILE_REPLACE to ask
for object replacement mechanism to kick in.

Later, we could add another flag bit to tell the function to return an
error instead of dying and then remove the misguided "call read_object()

git-sh-i18n--envsubst: our own envsubst(1) for eval_gettext()

Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.

We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.

These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:

 * Added our git-compat-util.h header for xrealloc() and friends.

 * Removed inclusion of gettext-specific headers.

 * Removed most of main() and replaced it with my own. The modified
   version only does option parsing for --variables. That's all it
   needs.

 * Modified error() invocations to use our error() instead of
   error(3).

 * Replaced the gettext XNMALLOC(n, size) macro with just
   xmalloc(n). Since XNMALLOC() only allocated char's.

 * Removed the string_list_destroy function. It's redundant (also in
   the upstream code).

 * Replaced the use of stdbool.h (a C99 header) by doing the following
   replacements on the code:

    * s/bool/unsigned short int/g
    * s/true/1/g
    * s/false/0/g

add, merge, diff: do not use strcasecmp to compare config variable names

The config machinery already makes section and variable names
lowercase when parsing them, so using strcasecmp for comparison just
feels wasteful.  No noticeable change intended.

Submodules: Don't parse .gitmodules when it contains, merge conflicts

Commands like "git status", "git diff" and "git fetch" would fail when the
.gitmodules file contained merge conflicts because the config parser would
call die() when hitting the conflict markers:

    "fatal: bad config file line <n> in <path>/.gitmodules"

While this behavior was on the safe side, it is really unhelpful to the
user to have commands like status and diff fail, as these are needed to
find out what's going on. And the error message is only mildly helpful,
as it points to the right file but doesn't mention that it is unmerged.
Users of git gui were not shown any conflicts at all when this happened.

Improve the situation by checking if the index records .gitmodules as
unmerged. When that is the case we can't make any assumptions about the
configuration to be found there after the merge conflict is resolved by
the user, so assume that all recursion is disabled unless .git/config or
the global config say otherwise.

As soon as the merge conflict is resolved and the .gitmodules file has
been staged subsequent commands again honor any configuration done there.
