615c6d6bda Merge branch 'skip-gettext-when-possible'
This topic branch allows us to skip the gettext initialization
when the locale directory does not even exist.

This saves 150ms out of 210ms for a simply `git version` call on
Windows, and it most likely will help scripts that call out to
`git.exe` hundreds of times.

32a187f346 mingw: fix isatty() after dup2()
We newly 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.

This fixes https://github.com/git-for-windows/git/issues/1077

11db8815c4 mingw: ensure valid CTYPE
A change between versions 2.4.1 and 2.6.0 of the MSYS2 runtime modified
how Cygwin's runtime (and hence Git for Windows' MSYS2 runtime
derivative) handles locales: d16a56306d (Consolidate wctomb/mbtowc calls
for POSIX-1.2008, 2016-07-20).

An unintended side-effect is that "cold-calling" into the POSIX
emulation will start with a locale based on the current code page,
something that Git for Windows is very ill-prepared for, as it expects
to be able to pass a command-line containing non-ASCII characters to the
shell without having those characters munged.

One symptom of this behavior: when `git clone` or `git fetch` shell out
to call `git-upload-pack` with a path that contains non-ASCII
characters, the shell tried to interpret the entire command-line
(including command-line parameters) as executable path, which obviously
must fail.

The fix we introduced in Git for Windows will be made obsolete by a more

branch.

But we still can introduce a regression test that verifies that this bug
will be caught very quickly, if reintroduced.

21a7a46e43 t9001: work around hard-to-debug hangs
Just like the workaround we added for t9116, t9001.83 hangs sometimes --
but not always! -- when being run in the Git for Windows SDK.

The issue seems to be related to redirection via a pipe, but it is really
hard to diagnose, what with git.exe (a non-MSYS2 program) calling a Perl
script (which is executed by an MSYS2 Perl), piping into another MSYS2
program.

As hunting time is scarce these days, simply work around this for now and
leave the real diagnosis and resolution for later.

b8aa23484e Merge branch 'visual-studio'
This topic branch teaches the project generator to generate a Visual
Studio solution, ready to be opened in Visual Studio 2010 or later.

The idea, of course, is to let some automatic build job generate and
commit the project files with

	make MSVC=1 vcxproj

and then (force-)push to a special-purpose branch.

The major part of this branch thicket concerns itself not only with
generating the Visual Studio project files, but making sure that the
user can then run the test suite from a regular Git Bash (i.e. *not*
requiring a Git for Windows SDK), e.g. by running

	cd t
	prove --timer --jobs 15 ./t[0-9]*.sh

7919da9d99 Unbreak interactive GPG prompt upon signing
With the recent update in efee955 (gpg-interface: check gpg signature
creation status, 2016-06-17), we ask GPG to send all status updates to
stderr, and then catch the stderr in an strbuf.

But GPG might fail, and send error messages to stderr. And we simply
do not show them to the user.

Even worse: this swallows any interactive prompt for a passphrase. And
detaches stderr from the tty so that the passphrase cannot be read.

So while the first problem could be fixed (by printing the captured
stderr upon error), the second problem cannot be easily fixed, and
presents a major regression.

So let's just revert commit efee9553a4.

4164203c3f gettext: avoid initialization if the locale dir is not present
The runtime of a simple `git.exe version` call on Windows is currently
dominated by the gettext setup, adding a whopping ~150ms to the ~210ms
total.

Given that this cost is added to each and every git.exe invocation goes
through common-main's invocation of git_setup_gettext(), and given that
scripts have to call git.exe dozens, if not hundreds, of times, this is
a substantial performance penalty.

This is particularly pointless when considering that Git for Windows
ships without localization (to keep the installer's size to a bearable
~34MB): all that time setting up gettext is for naught.

So let's be smart about it and skip setting up gettext if the locale
directory is not even present.

11389d5ce6 gettext: use a GIT_LOCALE_PATH relative to $(prefix)
On Windows, we simply pass a POSIX path to bindtextdomain(), relying on
the current libintl-8.dll implementation to handle that gracefully by
resolving the path relative to the "root" directory inferred from the
location of the .dll file itself.

However, not only does this rely on the custom patches of the gettext
library as shipped with MSYS2 (gettext's own source code is not prepared
to handle POSIX paths on Windows), it also means that Git itself cannot
use the `podir` variable at all because it does not handle absolute
POSIX paths in system_path() correctly, leaving them as-is.

This patch fixes that behavior by always using a GIT_LOCALE_PATH
relative to the (runtime) prefix.

fed65c3a81 fscache: remember not-found directories
Teach FSCACHE to remember "not found" directories.

This is a performance optimization.

FSCACHE is a performance optimization available for Windows.  It
intercepts Posix-style lstat() calls into an in-memory directory
using FindFirst/FindNext.  It improves performance on Windows by
catching the first lstat() call in a directory, using FindFirst/
FindNext to read the list of files (and attribute data) for the
entire directory into the cache, and short-cut subsequent lstat()
calls in the same directory.  This gives a major performance
boost on Windows.

However, it does not remember "not found" directories.  When STATUS
runs and there are missing directories, the lstat() interception
fails to find the parent directory and simply return ENOENT for the
file -- it does not remember that the FindFirst on the directory
failed. Thus subsequent lstat() calls in the same directory, each
re-attempt the FindFirst.  This completely defeats any performance
gains.

This can be seen by doing a sparse-checkout on a large repo and
then doing a read-tree to reset the skip-worktree bits and then
running status.

This change reduced status times for my very large repo by 60%.
