df561b60dc t9116: work around hard-to-debug hangs
As of a couple of weeks ago, t9116 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.

aa14f008b9 diffcore-rename: speed up register_rename_src
Teach register_rename_src() to see if new file pair
can simply be appended to the rename_src[] array before
performing the binary search to find the proper insertion
point.

This is a performance optimization.  This routine is called
during run_diff_files in status and the caller is iterating
over the sorted index, so we should expect to be able to
append in the normal case.  The existing insert logic is
preserved so we don't have to assume that, but simply take
advantage of it if possible.

4e4124f257 Carry non-locking status value in the environment.
If the user has specified '--no-lock-index' when calling git-status, it only seems reasonable that the user intends that option to be carried through to any child forks/procs as well. Currently, the '--no-lock-status' call is lost when submodules are checked. This change places the desired option into the environment, which is in turn passed down to all subsequent children.

With cmd_status checking for '--no-lock--status' first from args then from environment, we're able to keep the option set in all children.

b8fed353a8 poll: lazy-load GetTickCount64()
This fixes the compilation, actually, as we still did not make the jump to
post-Windows XP completely: we still compile with _WIN32_WINNT set to
0x0502 (which corresponds to Windows Server 2003 and is technically
greater than Windows XP's 0x0501).

However, GetTickCount64() is only available starting with Windows
Vista/Windows Server 2008.

Let's just lazy-load the function, which should also help Git for Windows
contributors who want to reinstate Windows XP support.

From Visual Studio 2015 Code Analysis: Warning C28159 Consider using
'GetTickCount64' instead of 'GetTickCount'.

Reason: GetTickCount overflows roughly every 49 days. Code that does not
take that into account can loop indefinitely. GetTickCount64 operates on
64 bit values and does not have that problem.

f95b5a31d1 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

c6c2e68970 Support Vagrant: quick & easy Linux virtual machine setup
When developing Git for Windows, we always have to ensure that we do not
break any non-Windows platforms, e.g. by introducing Windows-specific code
into the platform-independent source code.

At other times, it is necessary to test whether a bug is Windows-specific
or not, in order to send the bug report to the correct place. Having
access to a Linux-based Git comes in really handy in such a situation.

Vagrant offers a painless way to install and use a defined Linux
development environment on Windows (and other Operating Systems). We offer
a Vagrantfile to that end for two reasons:

1) To allow Windows users to gain the full power of Linux' Git

2) To offer users an easy path to verify that the issue they are about
   to report is really a Windows-specific issue; otherwise they would
   need to report it to git@vger.kernel.org instead.

Using it is easy: Download and install https://www.virtualbox.org/, then
download and install https://www.vagrantup.com/, then direct your
command-line window to the Git source directory containing the Vagrantfile
and run the commands:

	vagrant up
	vagrant ssh

See https://github.com/git-for-windows/git/wiki/Vagrant for details.

As part of switching Git for Windows' development environment from msysGit
to the MSys2-based Git SDK, this Vagrantfile was copy-edited from msysGit:

ff8e892d0c git: avoid calling aliased builtins via their dashed form
This is one of the few places where Git violates its own deprecation of
the dashed form. It is not necessary, either.

As of 595d59e2b5 (git.c: ignore pager.* when launching builtin as
dashed external, 2017-08-02), Git wants to ignore the pager.* config
setting when expanding aliases. So let's strip out the
check_pager_config(<command-name>) call from the copy-edited code.

85c30e5475 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.

This fixes https://github.com/git-for-windows/git/issues/871

57fcace688 msvc: avoid debug assertion windows in Debug Mode
For regular debugging, it is pretty helpful when a debug assertion in a
running application triggers a window that offers to start the debugger.

However, when running the test suite, it is not so helpful, in
particular when the debug assertions are then suppressed anyway because
we disable the invalid parameter checking (via invalidcontinue.obj, see
the comment in config.mak.uname about that object for more information).

So let's simply disable that window in Debug Mode (it is already
disabled in Release Mode).

df3c33b4ef msvc: add a Makefile target to pre-generate the VS solution
The entire idea of generating the VS solution makes only sense if we
generate it via Continuous Integration; otherwise potential users would
still have to download the entire Git for Windows SDK.

So let's just add a target in the Makefile that can be used to generate
said solution; The generated files will then be committed so that they
can be pushed to a branch ready to check out by Visual Studio users.

To make things even more useful, we also generate and commit other files
that are required to run the test suite, such as templates and
bin-wrappers: with this, developers can run the test suite in a regular
Git Bash (that is part of a regular Git for Windows installation) after
building the solution in Visual Studio.

f0c6948356 contrib/buildsystems: make 'Restore NuGet Packages' work in Visual Studio
Visual Studio has this very neat feature that you can get dependencies in
the form of NuGet packages, and even further: you can specify in a project
what NuGet packages it needs. These dependencies can then be fetched via
right-clicking the solution in the Solution Explorer and clicking the
"Restore NuGet Packages" entry.

This feature is so neat, in fact, that we want to support it in Git for
Windows. The idea is that we will be able to provide developers with a
checkout of the Git sources that can be built outside of the Git for
Windows SDK, using *only* Visual Studio.
