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.

After sending the pack, we call receive_status() which gets
both the "unpack" line and the ref status. Let's break these
into two functions so we can call the first part
independently.

The err_fd descriptor passed to the unpack() function is
intended to be handed off to the child index-pack, and our
async muxer will read until it gets EOF. However, if we
encounter an error before handing off the descriptor, we
must manually close(err_fd). Otherwise we will be waiting
for our muxer to finish, while the muxer is waiting for EOF
on err_fd.
We fixed an identical deadlock already in 49ecfa13f
(receive-pack: close sideband fd on early pack errors,
2013-04-19). But since then, the function grew a new
early-return in 722ff7f87 (receive-pack: quarantine objects
until pre-receive accepts, 2016-10-03), when we fail to
create a temporary directory. This return needs the same
treatment.

Since 650c44925 (common-main: call git_extract_argv0_path(),
2016-07-01), the argv[0] that is seen in cmd_main() of
individual programs is always the basename of the
executable, as common-main strips off the full path. This
can produce confusing results for git-daemon, which wants to
re-exec itself.
For instance, if the program was originally run as
"/usr/lib/git/git-daemon", it will try just re-execing
"git-daemon", which will find the first instance in $PATH.
If git's exec-path has not been prepended to $PATH, we may
find the git-daemon from a different version (or no
git-daemon at all).
Normally this isn't a problem. Git commands are run as "git
daemon", the git wrapper puts the exec-path at the front of
$PATH, and argv[0] is already "daemon" anyway. But running
git-daemon via its full exec-path, while not really a
recommended method, did work prior to 650c44925. Let's make
it work again.
The real goal of 650c44925 was not to munge argv[0], but to
reliably set the argv0_path global. The only reason it
munges at all is that one caller, the git.c wrapper,
piggy-backed on that computation to find the command
basename. Instead, let's leave argv[0] untouched in
common-main, and have git.c do its own basename computation.
While we're at it, let's drop the return value from
git_extract_argv0_path(). It was only ever used in this one
callsite, and its dual purposes is what led to this
confusion in the first place.
Note that by changing the interface, the compiler can
confirm for us that there are no other callers storing the
return value. But the compiler can't tell us whether any of
the cmd_main() functions (besides git.c) were relying on the
basename munging. However, we can observe that prior to
650c44925, no other cmd_main() functions did that munging,
and no new cmd_main() functions have been introduced since
then. So we can't be regressing any of those cases.

least 25% trailers. The documentation was updated to mention this new
functionality, but did not mention "user-configured trailer".
Further update the documentation to also mention "user-configured

The way "git stripspace" reads the configuration was not quite
kosher, in that the code forgot to probe for a possibly existing
repository (note: stripspace is designed to be usable outside the
repository as well). It read .git/config only when it was run from
the top-level of the working tree by accident. A recent change
b9605bc4f2 ("config: only read .git/config from configured repos",
2016-09-12) stopped reading the repository-local configuration file
".git/config" unless the repository discovery process is done, so
that .git/config is never read even when run from the top-level,
exposing the old bug more.
