We cannot rely on `uname -m` in Git for Windows' SDK to tell us what
architecture we are compiling for, as we can compile both 32-bit and
64-bit `git.exe` from a 64-bit SDK, but the `uname -m` in that SDK will
always report `x86_64`.
So let's go back to our original design. And make it explicitly
Windows-specific.

To support IPv6, Git provided fall back functions for Windows versions that
did not support IPv6. However, as Git dropped support for Windows XP and
prior, those functions are not needed anymore.
Removed those fallbacks by reverting commit[1] and using the functions
directly (without 'ipv6_' prefix).

When debugging Git, the criss-cross spawning of processes can make
things quite a bit difficult, especially when a Unix shell script is
thrown in the mix that calls a `git.exe` that then segfaults.
To help debugging such things, we introduce the `open_in_gdb()` function
which can be called at a code location where the segfault happens (or as
close as one can get); This will open a new MinTTY window with a GDB
that already attached to the current process.

This branch introduces support for reading the "Windows-wide" Git
configuration from `%PROGRAMDATA%\Git\config`. As these settings are

Between the libgit2 and the Git for Windows project, there has been a
discussion how we could share Git configuration to avoid duplication (or
worse: skew).
Earlier, libgit2 was nice enough to just re-use Git for Windows'
C:\Program Files (x86)\Git\etc\gitconfig
but with the upcoming Git for Windows 2.x, there would be more paths to
search, as we will have 64-bit and 32-bit versions, and the
corresponding config files will be in %PROGRAMFILES%\Git\mingw64\etc and
...\mingw32\etc, respectively.
Worse: there are portable Git for Windows versions out there which live
in totally unrelated directories, still.
Therefore we came to a consensus to use `%PROGRAMDATA%\Git\config` as the
location for shared Git settings that are of wider interest than just Git
for Windows.
Of course, the configuration in `%PROGRAMDATA%\Git\config` has the
widest reach, therefore it must take the lowest precedence, i.e. Git for
Windows can still override settings in its `etc/gitconfig` file.

Implement readlink() by reading NTFS reparse points. Works for symlinks
and directory junctions. If symlinks are disabled, fail with ENOSYS.
Signed-off-by: Karsten Blees <blees@dcon.de>
Windows paths are typically limited to MAX_PATH = 260 characters, even
though the underlying NTFS file system supports paths up to 32,767 chars.
This limitation is also evident in Windows Explorer, cmd.exe and many
other applications (including IDEs).
Particularly annoying is that most Windows APIs return bogus error codes
if a relative path only barely exceeds MAX_PATH in conjunction with the
current directory, e.g. ERROR_PATH_NOT_FOUND / ENOENT instead of the
infinitely more helpful ERROR_FILENAME_EXCED_RANGE / ENAMETOOLONG.
Many Windows wide char APIs support longer than MAX_PATH paths through the
file namespace prefix ('\\?\' or '\\?\UNC\') followed by an absolute path.
Notable exceptions include functions dealing with executables and the
current directory (CreateProcess, LoadLibrary, Get/SetCurrentDirectory) as
well as the entire shell API (ShellExecute, SHGetSpecialFolderPath...).
Introduce a handle_long_path function to check the length of a specified
path properly (and fail with ENAMETOOLONG), and to optionally expand long
paths using the '\\?\' file namespace prefix. Short paths will not be
modified, so we don't need to worry about device names (NUL, CON, AUX).
Contrary to MSDN docs, the GetFullPathNameW function doesn't seem to be
limited to MAX_PATH (at least not on Win7), so we can use it to do the
heavy lifting of the conversion (translate '/' to '\', eliminate '.' and
'..', and make an absolute path).
Add long path error checking to xutftowcs_path for APIs with hard MAX_PATH
limit.
Add a new MAX_LONG_PATH constant and xutftowcs_long_path function for APIs
that support long paths.
While improved error checking is always active, long paths support must be
explicitly enabled via 'core.longpaths' option. This is to prevent end
users to shoot themselves in the foot by checking out files that Windows
Explorer, cmd/bash or their favorite IDE cannot handle.
Test suite:
Test the case is when the full pathname length of a dir is close
to 260 (MAX_PATH).

Git for Windows has special code to retrieve the command-line parameters
(and even the environment) in UTF-16 encoding, so that they can be
converted to UTF-8. This is necessary because Git for Windows wants to
use UTF-8 encoded strings throughout its code, and the main() function
does not get the parameters in that encoding.
To do that, we used the __wgetmainargs() function, which is not even a
Win32 API function, but provided by the MINGW "runtime" instead.
Obviously, this method would not work with any other compiler than GCC,
and in preparation for compiling with Visual C++, we would like to avoid
that.
Lucky us, there is a much more elegant way: we simply implement wmain()
and link with -municode. The command-line parameters are passed to
wmain() encoded in UTF-16, as desired, and this method also works with
Visual C++ after adjusting the MSVC linker flags to force it to use
wmain().

Windows port learned to use nano-second resolution file timestamps.
* js/mingw-ns-filetime:
mingw: implement nanosecond-precision file times
mingw: replace MSVCRT's fstat() with a Win32-based implementation
mingw: factor out code to set stat() data
Since a9b8a09c3c (mingw: replace isatty() hack, 2016-12-22), we handle
isatty() by special-casing the stdin/stdout/stderr file descriptors,
caching the return value. However, we missed the case where dup2()
overrides the respective file descriptor.
That poses a problem e.g. where the `show` builtin asks for a pager very
early, the `setup_pager()` function sets the pager depending on the
return value of `isatty()` and then redirects stdout. Subsequently,
`cmd_log_init_finish()` calls `setup_pager()` *again*. What should
happen now is that `isatty()` reports that stdout is *not* a TTY and
consequently stdout should be left alone.
Let's override dup2() to handle this appropriately.

On Windows, the authoritative environment is encoded in UTF-16. In Git
for Windows, we convert that to UTF-8 (because UTF-16 is *such* a
foreign idea to Git that its source code is unprepared for it).
Previously, out of performance concerns, we converted the entire
environment to UTF-8 in one fell swoop at the beginning, and upon
putenv() and run_command() converted it back.
Having a private copy of the environment comes with its own perils: when
a library used by Git's source code tries to modify the environment, it
does not really work (in Git for Windows' case, libcurl, see
https://github.com/git-for-windows/git/compare/bcad1e6d58^...bcad1e6d58^2
for a glimpse of the issues).
Hence, it makes our environment handling substantially more robust if we
switch to on-the-fly-conversion in `getenv()`/`putenv()` calls. Based
on an initial version in the MSVC context by Jeff Hostetler, this patch
makes it so.
Surprisingly, this has a *positive* effect on speed: at the time when
the current code was written, we tested the performance, and there were
*so many* `getenv()` calls that it seemed better to convert everything
in one go. In the meantime, though, Git has obviously been cleaned up a
bit with regards to `getenv()` calls so that the Git processes spawned
by the test suite use an average of only 40 `getenv()`/`putenv()` calls
over the process lifetime.
Speaking of the entire test suite: the total time spent in the
re-encoding in the current code takes about 32.4 seconds (out of 113
minutes runtime), whereas the code introduced in this patch takes only
about 8.2 seconds in total. Not much, but it proves that we need not be
concerned about the performance impact introduced by this patch.

Note: This can cause performance issues when using Git variants with

second-precision file times, a nanosecond-aware Git will think that
pretty much every single file listed in the index is out of date.

On Windows, strftime() does not silently ignore invalid formats, but
warns about them and then returns 0 and sets errno to EINVAL.
Unfortunately, Git does not expect such a behavior, as it disagrees
with strftime()'s semantics on Linux. As a consequence, Git
misinterprets the return value 0 as "I need more space" and grows the
buffer. As the larger buffer does not fix the format, the buffer grows
and grows and grows until we are out of memory and abort.
Ideally, we would switch off the parameter validation just for
strftime(), but we cannot even override the invalid parameter handler
via _set_thread_local_invalid_parameter_handler() using MINGW because
that function is not declared. Even _set_invalid_parameter_handler(),
which *is* declared, does not help, as it simply does... nothing.
So let's just bite the bullet and override strftime() for MINGW and
abort on an invalid format string. While this does not provide the
best user experience, it is the best we can do.

When Git's source code calls isatty(), it really asks whether the
respective file descriptor is connected to an interactive terminal.
Windows' _isatty() function, however, determines whether the file
descriptor is associated with a character device. And NUL, Windows'
equivalent of /dev/null, is a character device.
Which means that for years, Git mistakenly detected an associated
interactive terminal when being run through the test suite, which
almost always redirects stdin, stdout and stderr to /dev/null.
This bug only became obvious, and painfully so, when the new
bisect--helper entered the `pu` branch and made the automatic build & test

The tempfile (hence its user lockfile) API lets the caller to open
a file descriptor to a temporary file, write into it and then
finalize it by first closing the filehandle and then either
removing or renaming the temporary file. When the process spawns a
subprocess after obtaining the file descriptor, and if the
subprocess has not exited when the attempt to remove or rename is
made, the last step fails on Windows, because the subprocess has
the file descriptor still open. Open tempfile with O_CLOEXEC flag
to avoid this (on Windows, this is mapped to O_NOINHERIT).
* bw/mingw-avoid-inheriting-fd-to-lockfile:

There are certain house-keeping tasks that need to be performed at
the very beginning of any Git program, and programs that are not
built-in commands had to do them exactly the same way as "git"
potty does. It was easy to make mistakes in one-off standalone
programs (like test helpers). A common "main()" function that
calls cmd_main() of individual program has been introduced to
make it harder to make mistakes.
* jk/common-main:
mingw: declare main()'s argv as const
common-main: call git_setup_gettext()
common-main: call restore_sigpipe_to_default()
common-main: call sanitize_stdfds()
common-main: call git_extract_argv0_path()
add an extra level of indirection to main()
When the index is locked and child processes inherit the handle to
said lock and the parent process wants to remove the lock before the
child process exits, on Windows there is a problem: it won't work
because files cannot be deleted if a process holds a handle on them.
The symptom:
Rename from 'xxx/.git/index.lock' to 'xxx/.git/index' failed.
Should I try again? (y/n)
Spawning child processes with bInheritHandles==FALSE would not work
because no file handles would be inherited, not even the hStdXxx
handles in STARTUPINFO (stdin/stdout/stderr).
Opening every file with O_NOINHERIT does not work, either, as e.g.
git-upload-pack expects inherited file handles.
This leaves us with the only way out: creating temp files with the
O_NOINHERIT flag. This flag is Windows-specific, however. For our
purposes, it is equivalent to O_CLOEXEC (which does not exist on
Windows), so let's just open temporary files with the O_CLOEXEC flag and
map that flag to O_NOINHERIT on Windows.
As Eric Wong pointed out, we need to be careful to handle the case where
the Linux headers used to compile Git support O_CLOEXEC but the Linux
kernel used to run Git does not: it returns an EINVAL.
This fixes the test that we just introduced to demonstrate the problem.

On Windows, when writing to a pipe fails, errno is always

According to the documentation, there are two cases in which write()
triggers EINVAL: the buffer is NULL, or the length is odd but the mode
is 16-bit Unicode (the broken pipe is not mentioned as possible cause).
Git never sets the file mode to anything but binary, therefore we know
that errno should actually be EPIPE if it is EINVAL and the buffer is
not NULL.
