The patch subcommand of "git add -i" was meant to have paths

3efd0bedc6 config: add conditional include
Sometimes a set of repositories want to share configuration settings
among themselves that are distinct from other such sets of repositories.
A user may work on two projects, each of which have multiple
repositories, and use one user.email for one project while using another
for the other.

Setting $GIT_DIR/.config works, but if the penalty of forgetting to
update $GIT_DIR/.config is high (especially when you end up cloning
often), it may not be the best way to go. Having the settings in
~/.gitconfig, which would work for just one set of repositories, would
not well in such a situation. Having separate ${HOME}s may add more
problems than it solves.

Extend the include.path mechanism that lets a config file include
another config file, so that the inclusion can be done only when some
conditions hold. Then ~/.gitconfig can say "include config-project-A
only when working on project-A" for each project A the user works on.

In this patch, the only supported grouping is based on $GIT_DIR (in
absolute path), so you would need to group repositories by directory, or
something like that to take advantage of it.

We already have include.path for unconditional includes. This patch goes
with includeIf.<condition>.path to make it clearer that a condition is
required. The new config has the same backward compatibility approach as
include.path: older git versions that don't understand includeIf will
simply ignore them.

bd4d9d993c t/interop: add test of old clients against modern git-daemon
This test just checks that old clients can clone and fetch
from a newer git-daemon. The opposite should also be true,
but it's hard to test ancient versions of git-daemon because
they lack basic options like "--listen".

Note that we have to make a slight tweak to the
lib-git-daemon helper from the regular tests, so that it
starts the daemon with our correct git.a version.

3d8936153d t: add an interoperability test harness
The current test suite is good at letting you test a
particular version of Git. But it's not very good at letting
you test _two_ versions and seeing how they interact (e.g.,
one cloning from the other).

This commit adds a test harness that will build two
arbitrary versions of git and make it easy to call them from
inside your tests. See the README and the example script for
details.

a91aca44bf ref-filter: use separate cache for contains_tag_algo
The algorithm which powers "tag --contains" uses the
TMP_MARK and UNINTERESTING bits, but never cleans up after
itself. As a result, stale UNINTERESTING bits may impact
later traversals (like "--merged").

We could fix this by clearing the bits after we're done with
the --contains traversal. That would be enough to fix the
existing problem, but it leaves future developers in a bad
spot: they cannot add other traversals that operate
simultaneously with --contains (e.g., if you wanted to add
"--no-contains" and use both filters at the same time).

Instead, we can use a commit slab to store our cached
results, which will store the bits outside of the commit
structs entirely. This adds an extra level of indirection,
but in my tests (running "git tag --contains HEAD" on
linux.git), there was no measurable slowdown.

ce83eadd9a real_pathdup(): fix callsites that wanted it to die on error
In 4ac9006f83 (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.

ba69f92db6 send-pack: read "unpack" status even on pack-objects failure
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.

40d05d04dd send-pack: improve unpack-status error messages
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.

6cdad1f133 receive-pack: fix deadlock when we cannot create tmpdir
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.
