85d168deca contrib/buildsystems: redirect errors of the dry run into a log file
Rather than swallowing the errors, it is better to have them in a file.

To make it obvious what this is about, use the file name
'msvc-build-makedryerrors.txt'.

Further, if the output is empty, simply delete that file. As we target
Git for Windows' SDK (which, unlike its predecessor msysGit, offers Perl
versions newer than 5.8), we can use the quite readable syntax `if -f -z
$ErrsFile` (available in Perl >=5.10).

Note that the file will contain the new values of the GIT_VERSION and
GITGUI_VERSION if they were generated by the make file. They are omitted
if the release is tagged and indentically defined in their respective
GIT_VERSION_GEN file DEF_VER variables.

101b814af9 contrib/buildsystems: ignore gettext stuff
Git's build contains steps to handle internationalization. This caused
hiccups in the parser used to generate QMake/Visual Studio project files.

As those steps are irrelevant in this context, let's just ignore them.

df168c081c contrib/buildsystems: handle quoted spaces in filenames
The engine.pl script expects file names not to contain spaces. However,
paths with spaces are quite prevalent on Windows. Use shellwords() rather
than split() to parse them correctly.

347fccc55c contrib/buildsystems: ignore invalidcontinue.obj
Since 4b623d8 (MSVC: link in invalidcontinue.obj for better POSIX
compatibility, 2014-03-29), invalidcontinue.obj is linked in the MSVC
build, but it was not parsed correctly by the buildsystem. Ignore it, as
it is known to Visual Studio and will be handled elsewhere.

Also only substitute filenames ending with .o when generating the
source .c filename, otherwise we would start to expect .cbj files to
generate .obj files (which are not generated by our build)...

In the future there may be source files that produce .obj files
so keep the two issues (.obj files with & without source files)
separate.

eec58c4bfa Vcproj.pm: list git.exe first to be startup project
Visual Studio takes the first listed application/library as the default

Detect the 'git' project and place it the head of the apps list, rather
than the tail.

Export the apps list before libs list for both the projects and global
structures of the .sln file.

53e836fb57 Vcproj.pm: auto-generate GUIDs
We ran out GUIDs. Again. But there is no need to: we can generate them
semi-randomly from the target file name of the project.

Note: the Vcproj generator is probably only interesting for historical
reasons; nevertheless, the upcoming Vcxproj generator (to support modern
Visual Studio versions) is based on the Vcproj generator and it is
better to fix this here first.

56f5d3a204 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).

903b76ad06 msvc: support building Git using MS Visual C++
With this patch, Git can be built using the Microsoft toolchain, via:

	make MSVC=1 [DEBUG=1]

Third party libraries are built from source using the open source
"vcpkg" tool set. See https://github.com/Microsoft/vcpkg

On a first build, the vcpkg tools and the third party libraries are
automatically downloaded and built. DLLs for the third party libraries
are copied to the top-level (and t/helper) directory to facilitate
debugging. See compat/vcbuild/README.

A series of .bat files are invoked by the Makefile to find the location
of the installed version of Visual Studio and the associated compiler
tools (essentially replicating the environment setup performed by a
"Developer Command Prompt"). This should find the most recent VS2015 or
VS2017 installation. Output from these scripts are used by the Makefile
to define compiler and linker pathnames and -I and -L arguments.

The build produces .pdb files for both debug and release builds.

Note: This commit was squashed from an organic series of commits
developed between 2016 and 2018 in Git for Windows' `master` branch.
This combined commit eliminates the obsolete commits related to fetching
NuGet packages for third party libraries. It is difficult to use NuGet
packages for C/C++ sources because they may be built by earlier versions
of the MSVC compiler and have CRT version and linking issues.
Additionally, the C/C++ NuGet packages that were using tended to not be
updated concurrently with the sources.  And in the case of cURL and
OpenSSL, this could expose us to security issues.

b8c72e3834 msvc: define O_ACCMODE
This constant is not defined in MSVC's headers.

In UCRT's fcntl.h, _O_RDONLY, _O_WRONLY and _O_RDWR are defined as 0, 1
and 2, respectively. Yes, that means that UCRT breaks with the tradition
that O_RDWR == O_RDONLY | O_WRONLY.

It is a perfectly legal way to define those constants, though, therefore
we need to take care of defining O_ACCMODE accordingly.

This is particularly important in order to keep our "open() can set
errno to EISDIR" emulation working: it tests that (flags & O_ACCMODE) is
not identical to O_RDONLY before going on to test specifically whether
the file for which open() reported EACCES is, in fact, a directory.

7b650d16fa mingw: replace mingw_startup() hack
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().

097f643989 t0001 (mingw): do not expect specific order of stdout/stderr
When redirecting stdout/stderr to the same file, we cannot guarantee

In fact, in this test case, it seems that an MSVC build always prints

the *presence* of both outputs, so let's relax the test a little.

80df6c477c Merge branch 'mingw-expand-absolute-user-path'
When compiling Git with a runtime prefix (so that it can be installed
into any location, finding its libexec/ directory relative to the
location of the `git` executable), it is convenient to provide
"absolute" Unix-y paths e.g. for http.sslCAInfo, and have those absolute
paths be resolved relative to the runtime prefix.

This patch makes it so for Windows. It is up for discussion whether we
want this for other platforms, too, as long as building with
RUNTIME_PREFIX.

ee11bd2a5d .gitattributes: ensure t/oid-info/* has eol=lf
The new test_oid machinery in the test library requires reading
some information from t/oid-info/hash-info and t/oid-info/oid.
The shell logic that reads from these files is sensitive to CRLF
line endings, causing a failure when the test suite is run on a
Windows machine that converts LF to CRLF: the test suite fails
with a "bad hash algorithm" message, but does not record any
failed test cases. This caused CI builds to pass because they
fail only after reporting the failed test cases.

Exclude the files in this folder from this conversion.
