configuring individual submodules (name to path mapping, URL where to
obtain the submodule, etc.) while other configuration like the number of
jobs to use when fetching submodules should be a part of the

On Cygwin, similar to Windows, "git push //server/share/repository"
ought to mean a repository on a network share that can be accessed
locally, but this did not work correctly due to stripping the double
slashes at the beginning.
This may need to be heavily tested before it gets unleashed to the
wild, as the change is at a fairly low-level code and would affect
not just the code to decide if the push destination is local. There
may be unexpected fallouts in the path normalization.

If we get a repo path like "-repo.git", we may try to invoke
"git-upload-pack -repo.git". This is going to fail, since
upload-pack will interpret it as a set of bogus options. But
let's reject this before we even run the sub-program, since
we would not want to allow any mischief with repo names that
actually are real command-line options.
You can still ask for such a path via git-daemon, but there's no
security problem there, because git-daemon enters the repo itself
and then passes "." on the command line.

If you have a GIT_PROXY_COMMAND configured, we will run it
with the host/port on the command-line. If a URL contains a
mischievous host like "--foo", we don't know how the proxy
command may handle it. It's likely to break, but it may also
do something dangerous and unwanted (technically it could
even do something useful, but that seems unlikely).
We should err on the side of caution and reject this before
we even run the command.
The hostname check matches the one we do in a similar
circumstance for ssh. The port check is not present for ssh,
but there it's not necessary because the syntax is "-p
<port>", and there's no ambiguity on the parsing side.
It's not clear whether you can actually get a negative port
to the proxy here or not. Doing:
git fetch git://remote:-1234/repo.git
keeps the "-1234" as part of the hostname, with the default
port of 9418. But it's a good idea to keep this check close
to the point of running the command to make it clear that
there's no way to circumvent it (and at worst it serves as a
belt-and-suspenders check).

We reject hostnames that start with a dash because they may
be confused for command-line options. Let's factor out that
notion into a helper function, as we'll use it in more
places. And while it's simple now, it's not clear if some
systems might need more complex logic to handle all cases.

When commands like "git fetch" talk with ssh://$rest_of_URL/, the
code splits $rest_of_URL into components like host, port, etc., and
then spawns the underlying "ssh" program by formulating argv[] array
that has:
- the path to ssh command taken from GIT_SSH_COMMAND, etc.
- dashed options like '-batch' (for Tortoise), '-p <port>' as
needed.
- ssh_host, which is supposed to be the hostname parsed out of
$rest_of_URL.
- then the command to be run on the other side, e.g. git
upload-pack.
If the ssh_host ends up getting '-<anything>', the argv[] that is
used to spawn the command becomes something like:
{ "ssh", "-p", "22", "-<anything>", "command", "to", "run", NULL }
which obviously is bogus, but depending on the actual value of
"<anything>", will make "ssh" parse and use it as an option.
Prevent this by forbidding ssh_host that begins with a "-".

The tests for protocol.allow actually set that variable in
the on-disk config, run a series of tests, and then never
clean up after themselves. This means that whatever tests we
run after have protocol.allow=never, which may influence
their results.
In most cases we either exit after running these tests, or
do another round of test_proto(). In the latter case, this happens to
work because:
1. Tests of the GIT_ALLOW_PROTOCOL environment variable
override the config.
2. Tests of the specific config "protocol.foo.allow"
override the protocol.allow config.
3. The next round of protocol.allow tests start off by
setting the config to a known value.
However, it's a land-mine waiting to trap somebody adding
new tests to one of the t581x test scripts. Let's make sure
we clean up after ourselves.

Since commit 612c49e94d ("credential-cache: add tests for XDG
functionality", 17-03-2017), the cygwin build has been failing all the
new tests added by that commit. In particular, the 'git credential-cache
exit' command, as part of the test cleanup code, has been die-ing with
the message:
fatal: read error from cache daemon: Connection reset by peer
As this git command is part of an && chain in a 'test_when_finished'
call, the remaining test cleanup is not happening, so practically all
remaining tests fail due to the unexpected presence of various socket
files and directories.
A simple means of getting the tests to pass, is to simply ignore the
failure of 'git credential-cache exit' command and make sure all test
cleanup is done. For example, the diff for test #12 would look like:
diff --git a/t/t0301-credential-cache.sh b/t/t0301-credential-cache.sh
index fd92533ac..87e5001bb 100755
--- a/t/t0301-credential-cache.sh

- git credential-cache exit &&
+ (git credential-cache exit || :) &&
rmdir -p .cache/git/credential/
" &&
test_path_is_missing "$HOME/.git-credential-cache" &&
... and so on for all remaining tests. While this does indeed make all
tests pass, it is not really a solution.
As an aside, while looking to debug this issue, I added the '--debug'
option to the invocation of the 'git-credential-cache--daemon' child
process (see the spawn_daemon() function). This not only fixed the tests,
but also stopped git-credential-cache exiting with a failure. Since the
only effect of passing '--debug' was to suppress the redirection of stderr
to the bit-bucket (/dev/null), I have no idea why this seems to fix the
protocol interaction between git and git-credential-cache--daemon. (I
did think that maybe it was a timing issue, so I tried sleeping before
reading from the daemon on Linux, but that only slowed down the tests!)
All descriptions of the "Connection reset by peer" error, that I could
find, say that the peer had destroyed the connection before the client
attempted to perform I/O on the connection. Since the daemon does not
respond to an "exit" message from the client, it just closes the socket
and deletes the socket file (via the atexit handler), it seems that the
expected result is for the client to receive an EOF. Indeed, this is
exactly what seems to be happening on Linux. Also a comment in
credential-cache--daemon.c reads:
else if (!strcmp(action.buf, "exit")) {
/*
* It's important that we clean up our socket first, and then
* signal the client only once we have finished the cleanup.
* Calling exit() directly does this, because we clean up in
* our atexit() handler, and then signal the client when our
* process actually ends, which closes the socket and gives
* them EOF.
*/
exit(0);
}
On cygwin this is not the case, at least when not passing --debug to the
daemon, and the read following the "exit" gets an error with errno set
to ECONNRESET.
In order to suppress the fatal exit in this case, check the read error
for an ECONNRESET and return as if no data was read from the daemon.
This effectively converts an ECONNRESET into an EOF.

One of the tricks that `contrib/workdir/git-new-workdir` plays is to
making `packed-refs` in the new workdir a symlink to the `packed-refs`
file in the original repository. Before
42dfa7ecef ("commit_packed_refs(): use a staging file separate from
the lockfile", 2017-06-23), a lockfile was used as the staging file,
and because the `LOCK_NO_DEREF` was not used, the pointed-to file was
locked and modified.
But after that commit, the staging file was created using a tempfile,
with the end result that rewriting the `packed-refs` file in the
workdir overwrote the symlink rather than the original `packed-refs`
file.
Change `commit_packed_refs()` to use `get_locked_file_path()` to find
the path of the file that it should overwrite. Since that path was
properly resolved when the lockfile was created, this restores the
pre-42dfa7ecef behavior.
Also add a test case to document this use case and prevent a
regression like this from recurring.
