84e82df6ed connect: handle putty/plink also in GIT_SSH_COMMAND
Git for Windows has special support for the popular SSH client PuTTY:
when using PuTTY's non-interactive version ("plink.exe"), we use the -P
option to specify the port rather than OpenSSH's -p option. TortoiseGit
ships with its own, forked version of plink.exe, that adds support for
the -batch option, and for good measure we special-case that, too.

However, this special-casing of PuTTY only covers the case where the
user overrides the SSH command via the environment variable GIT_SSH
(which allows specifying the name of the executable), not
GIT_SSH_COMMAND (which allows specifying a full command, including
additional command-line options).

When users want to pass any additional arguments to (Tortoise-)Plink,
such as setting a private key, they are required to either use a shell
script named plink or tortoiseplink or duplicate the logic that is
already in Git for passing the correct style of command line arguments,
which can be difficult, error prone and annoying to get right.

This patch simply reuses the existing logic and expands it to cover
GIT_SSH_COMMAND, too.

Note: it may look a little heavy-handed to duplicate the entire
command-line and then split it, only to extract the name of the
executable. However, this is not a performance-critical code path, and
the code is much more readable this way.

7d0ac1974c 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.

1f7268433a 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.

7fbc6cfd65 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

64 bit values and does not have that problem.

ef8ba35e66 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:

0ec1f5bfd9 string-list: use ALLOC_GROW macro when reallocing string_list
Use ALLOC_GROW() macro when reallocing a string_list array
rather than simply increasing it by 32.  This is a performance
optimization.

During status on a very large repo and there are many changes,
a significant percentage of the total run time was spent
reallocing the wt_status.changes array.

This change decreased the time in wt_status_collect_changes_worktree()
from 125 seconds to 45 seconds on my very large repository.

e99f9eb97c 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

475e2c0212 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

0e32c514ce 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).

604ecb5999 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.

313a298f13 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.
