The code to parse "git -c VAR=VAL cmd" and set configuration
variable for the duration of cmd had two small bugs, which have
been fixed.
This supersedes jc/config-case-cmdline topic that has been discarded.
* jc/config-case-cmdline-take-2:
config: use git_config_parse_key() in git_config_parse_parameter()
config: move a few helper functions up
The code to parse the command line "git grep <patterns>... <rev>
[[--] <pathspec>...]" has been cleaned up, and a handful of bugs
have been fixed (e.g. we used to check "--" if it is a rev).
* jk/grep-no-index-fix:
grep: treat revs the same for --untracked as for --no-index
grep: do not diagnose misspelt revs with --no-index
grep: avoid resolving revision names in --no-index case
grep: fix "--" rev/pathspec disambiguation
grep: re-order rev-parsing loop
grep: do not unnecessarily query repo for "--"
grep: move thread initialization a little lower
"git ls-remote" and "git archive --remote" are designed to work
without being in a directory under Git's control. However, recent
updates revealed that we randomly look into a directory called
.git/ without actually doing necessary set-up when working in a
repository. Stop doing so.
* jn/remote-helpers-with-git-dir:
remote helpers: avoid blind fall-back to ".git" when setting GIT_DIR
remote: avoid reading $GIT_DIR config in non-repo
Code to read submodule.<name>.ignore config did not state the
variable name correctly when giving an error message diagnosing
misconfiguration.
* sb/submodule-config-parse-ignore-fix:
submodule-config: correct error reporting for invalid ignore value
"git push" had a handful of codepaths that could lead to a deadlock
when unexpected error happened, which has been fixed.
* jk/push-deadlock-regression-fix:
send-pack: report signal death of pack-objects
send-pack: read "unpack" status even on pack-objects failure
send-pack: improve unpack-status error messages
send-pack: use skip_prefix for parsing unpack status
send-pack: extract parsing of "unpack" response
receive-pack: fix deadlock when we cannot create tmpdir
Map both old addresses to the new, hopefully more permanent one.

Change the documentation for push.tracking=* to re-include a mention
of what "tracking" does.
The "tracking" option was renamed to "upstream" back in
53c4031 ("push.default: Rename 'tracking' to 'upstream'", 2011-02-16),
this section was then subsequently rewritten in 87a70e4 ("config doc:
rewrite push.default section", 2013-06-19) to remove any mention of
"tracking".
Maybe we should just warn or die nowadays if this option is in the
config, but I had some old config of mine use this option, I'd
forgotten that it was a synonym, and nothing in git's documentation
mentioned that.
That's bad, either we shouldn't support it at all, or we should
document what it does. This patch does the latter.

git status provides a porcelain mode for porcelain writers with a
supposedly stable (plumbing) interface.
7a76c28ff2 ("status: disable translation when --porcelain is used", 2014-03-20)
made sure that ahead/behind info is not translated (i.e. is stable).
Make sure that the remaining two strings (initial commit, detached head)
are stable, too.
These changes are for the v1 porcelain interface. While we do have a perfectly
stable v2 porcelain interface now, some tools (such as
powerline-gitstatus) are written against v1 and profit from fixing v1
without any changes on their side.

If we parse a remote alternates (or http-alternates), we
expect relative lines like:
../../foo.git/objects
which we convert into "$URL/../foo.git/" (and then use that
as a base for fetching more objects).
But if the remote feeds us nonsense like just:
../
we will try to blindly strip the last 7 characters, assuming
they contain the string "objects". Since we don't _have_ 7
characters at all, this results in feeding a small negative
value to strbuf_add(), which converts it to a size_t,
resulting in a big positive value. This should consistently
fail (since we can't generall allocate the max size_t minus
7 bytes), so there shouldn't be any security implications.
Let's fix this by using strbuf_strip_suffix() to drop the
characters we want. If they're not present, we'll ignore the
alternate (in theory we could use it as-is, but the rest of
the http-walker code unconditionally tacks "objects/" back
on, so it is it not prepared to handle such a case).

In 4ac9006f832 (real_path: have callers use real_pathdup and
strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path())
pattern to use real_pathdup() directly.
The problem with this change is that real_path() calls
strbuf_realpath() with die_on_error = 1 while real_pathdup() calls
it with die_on_error = 0. Meaning that in cases where real_path()
causes Git to die() with an error message, real_pathdup() is silent
and returns NULL instead.
The callers, however, are ill-prepared for that change, as they expect
the return value to be non-NULL (and otherwise the function died
with an appropriate error message).
Fix this by extending real_pathdup()'s signature to accept the
die_on_error flag and simply pass it through to strbuf_realpath(),
and then adjust all callers after a careful audit whether they would
handle NULLs well.

If our pack-objects sub-process dies of a signal, then it
likely didn't have a chance to write anything useful to

If the local pack-objects of a push fails, we'll tell the
user about it. But one likely cause is that the remote
index-pack stopped reading for some reason (because it
didn't like our input, or encountered another error). In
that case we'd expect the remote to report more details to
us via the "unpack ..." status line. However, the current
code just hangs up completely, and the user never sees it.
Instead, let's call receive_unpack_status(), which will
complain on stderr with whatever reason the remote told us.
Note that if our pack-objects fails because the connection
was severed or the remote just crashed entirely, then our
packet_read_line() call may fail with "the remote end hung
up unexpectedly". That's OK. It's a more accurate
description than what we get now (which is just "some refs
failed to push").
This should be safe from any deadlocks. At the point we make
this call we'll have closed the writing end of the
connection to the server (either by handing it off to
a pack-objects which exited, explicitly in the stateless_rpc
case, or by doing a half-duplex shutdown for a socket). So
there should be no chance that the other side is waiting
for the rest of our pack-objects input.

When the remote tells us that the "unpack" step failed, we
show an error message. However, unless you are familiar with
the internals of send-pack and receive-pack, it was not
clear that this represented an error on the remote side.
Let's re-word to make that more obvious.
Likewise, when we got an unexpected packet from the other
end, we complained with a vague message but did not actually
show the packet. Let's fix that.
And finally, neither message was marked for translation. The
message from the remote probably won't be translated, but
there's no reason we can't do better for the local half.
