mmap emulation on Windows has been optimized and work better without
consuming paging store when not needed.
* js/win32-mmap:
mmap(win32): avoid expensive fstat() call
mmap(win32): avoid copy-on-write when it is unnecessary
win32mmap: set errno appropriately

Some Windows SDK lacks pthread_sigmask() implementation and fails
to compile the recently updated "git push" codepath that uses it.
* jk/push-client-deadlock-fix:
Windows: only add a no-op pthread_sigmask() when needed
Windows: add pthread_sigmask() that does nothing
t5504: drop sigpipe=ok from push tests
fetch-pack: isolate sigpipe in demuxer thread
send-pack: isolate sigpipe in demuxer thread
run-command: teach async threads to ignore SIGPIPE
send-pack: close demux pipe before finishing async process

"git mv old new" did not adjust the path for a submodule that lives
as a subdirectory inside old/ directory correctly.
* sb/mv-submodule-fix:
mv: allow moving nested submodules

The "user.useConfigOnly" configuration variable makes it an error
if users do not explicitly set user.name and user.email. However,
its check was not done early enough and allowed another error to
trigger, reporting that the default value we guessed from the
system setting was unusable. This was a suboptimal end-user
experience as we want the users to set user.name/user.email without
relying on the auto-detection at all.
* da/user-useconfigonly:
ident: give "please tell me" message upon useConfigOnly error
ident: check for useConfigOnly before auto-detection of name/email

The test scripts for "git p4" (but not "git p4" implementation
itself) has been updated so that they would work even on a system
where the installed version of Python is python 3.
* ld/p4-test-py3:
git-p4 tests: time_in_seconds should use $PYTHON_PATH
git-p4 tests: work with python3 as well as python2
git-p4 tests: cd to / before running python

In f924b52 (Windows: add pthread_sigmask() that does nothing,
2016-05-01), we introduced a no-op for Windows. However, this breaks
building Git in Git for Windows' SDK because pthread_sigmask() is
already a no-op there, #define'd in the pthread_signal.h header in
/mingw64/x86_64-w64-mingw32/include/.
Let's wrap the definition of pthread_sigmask() in a guard that skips
it when compiling with MinGW-w64' headers.

"git submodule" reports the paths of submodules the command

On Cygwin, object creation uses the "create a temporary and then
rename it to the final name" pattern, not "create a temporary,
hardlink it to the final name and then unlink the temporary"
pattern.
This is necessary to use Git on Windows shared directories, and is
already enabled for the MinGW and plain Windows builds. It also
has been used in Cygwin packaged versions of Git for quite a while.
See http://thread.gmane.org/gmane.comp.version-control.git/291853
($gmane/275680, $gmane/291853).

A partial rewrite of "git submodule" in the 2.7 timeframe changed

A change back in version 2.7 to "git branch" broke display of a
symbolic ref in a non-standard place in the refs/ hierarchy (we
expect symbolic refs to appear in refs/remotes/*/HEAD to point at
the primary branch the remote has, and as .git/HEAD to point at the
branch we locally checked out).

"git format-patch --help" showed `-s` and `--no-patch` as if these
are valid options to the command. We already hide `--patch` option
from the documentation, because format-patch is about showing the

A previous change introduced a call to pthread_sigmask() in order to block
SIGPIPE in a thread. Since there are no signal facilities on Windows that
are similar to POSIX signals, just ignore the request to block the signal.
In the particular case, the effect of blocking SIGPIPE on POSIX is that
write() calls return EPIPE when the reader closes the pipe. This is how
write() behaves on Windows.

When running "git blame $path" with unnormalized data in the index

"git add" would not have changed what is already in the index, due

corrected.

Update the git-p4 tests so that they work with both

strings which will be exchanged with Perforce.

On Windows, we have to emulate the fstat() call to fill out information
that takes extra effort to obtain, such as the file permissions/type.
If all we want is the file size, we can use the much cheaper
GetFileSizeEx() function (available since Windows XP).

Often we are mmap()ing read-only. In those cases, it is wasteful to map in
copy-on-write mode. Even worse: it can cause errors where we run out of
space in the page file.
So let's be extra careful to map files in read-only mode whenever
possible.

It is not really helpful when a `git fetch` fails with the message:
fatal: mmap failed: No error
In the particular instance encountered by a colleague of yours truly,
the Win32 error code was ERROR_COMMITMENT_LIMIT which means that the
page file is not big enough.
Let's make the message
fatal: mmap failed: File too large
instead, which is only marginally better, but which can be associated
with the appropriate work-around: setting `core.packedGitWindowSize` to
a relatively small value.

These were added by 8bf4bec (add "ok=sigpipe" to
test_must_fail and use it to fix flaky tests, 2015-11-27)
because we would racily die via SIGPIPE when the pack was
rejected by the other side.
But since we have recently de-flaked send-pack, we should be
able to tighten up these tests (including re-adding the
expected output checks).

In commit 9ff18fa (fetch-pack: ignore SIGPIPE in sideband
demuxer, 2016-02-24), we started using sigchain_push() to
ignore SIGPIPE in the async demuxer thread. However, this is
rather clumsy, as it ignores SIGPIPE for the entire process,
including the main thread. At the time we didn't have any
per-thread signal support, but we now we do. Let's use it.

If we get an error from pack-objects, we may exit
send_pack() early, before reading the server's status
response. In such a case, we may racily see SIGPIPE from our
async demuxer (which is trying to write that status back to
us), and we'd prefer to continue pushing the error up the
call stack, rather than taking down the whole process with
signal death.
This is safe to do because our demuxer just calls
recv_sideband, whose data writes are all done with
write_or_die(), which will notice SIGPIPE.
We do also write sideband 2 to stderr, and we would no
longer die on SIGPIPE there (if it were piped in the first
place, and if the piped program went away). But that's
probably a good thing, as it likewise should not abort the
push process at all (neither immediately by signal, nor
eventually by reporting failure back to the main thread).
