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).

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.

This special-cases various signals that are not supported on Windows,
such as SIGPIPE. These cause the UCRT to throw asserts (at least in
debug mode).
Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com>
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.

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++.

When redirecting stdout/stderr to the same file, we cannot guarantee
that stdout will come first.
In fact, in this test case, it seems that an MSVC build always prints
stderr first.
In any case, this test case does not want to verify the *order* but
the *presence* of both outputs, so let's relax the test a little.

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.

This patch series contains a couple of fixes revolving around testing
an installed Git, via GIT_TEST_INSTALLED=/path/to/git.
The original motivation for these patches is that Git for Windows wants
to provide a version where the Unix shell scripts are interpreted by
BusyBox (to reduce the footprint on disk, mainly), and we want to verify
that this actually works, and is not perchance missing any Unix shell
tool that is present in the Git for Windows SDK but is missing from the
installed set of files.
While the BusyBox-based Git for Windows is not ready for prime time,
this here patch series is, and might be useful for packagers who want to
verify a similar scenario.

In 8abfdf44c8 (tests: explicitly use `git.exe` on Windows,
2018-11-14), we made sure to use the `.exe` file extension when
using an absolute path to `git.exe`, to avoid getting confused with a
file or directory in the same place that lacks said file extension.
For the same reason, we need to handle test-tool.exe the same way.

This topic branch teaches Git to accept UNC paths of the form

Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
This topic branch addresses a problem identified in
https://github.com/git-for-windows/git/issues/439: while
cloning/fetching/pushing from "POSIX-ified UNC paths" (i.e. UNC paths
whose backslashes have been converted to forward slashes) works for some
time now, true UNC paths (with backslashes left intact) were handled
incorrectly. Example:
git clone //myserver/folder/repo.git
works, but
git clone \\myserver\folder\repo.git
(in CMD; in Git Bash, the backslashes would need to be doubled) used to
fail. The reason was an unexpected difference in command-line handling
between Win32 executables and MSYS2 ones (such as the shell that is used
by git-clone.exe to spawn git-upload-pack.exe).
This topic branch features a workaround *just* for the case where Git
passes stuff through sh.exe (which covers quite a few use cases,
though).

This topic branch allows us to specify absolute paths without the drive
prefix e.g. when cloning.
Example:

This will clone into a new directory C:\upstream-git, in line with how
Windows interprets absolute paths.

When building a PR, TRAVIS_BRANCH refers to the *target branch*.
Therefore, if a PR targets `master`, and `master` happened to be tagged,
we skipped the build by mistake.
Fix this by using TRAVIS_PULL_REQUEST_BRANCH (i.e. the *source branch*)
when available, falling back to TRAVIS_BRANCH (i.e. for CI builds, also
known as "push builds").

Sometimes, failures in a test case are actually caused by issues in
earlier test cases.
To make it easier to see those issues, let's attach the output from
before the failing test case (i.e. stdout/stderr since the previous
failing test case, or the start of the test script). This will be
visible in the "Attachments" of the details of the failed test.

The JUnit XML format lends itself to be presented in a powerful UI,
where you can drill down to the information you are interested in very
quickly.
For test failures, this usually means that you want to see the detailed
trace of the failing tests.
With Travis CI, we passed the `--verbose-log` option to get those
traces. However, that seems excessive, as we do not need/use the logs in
almost all of those cases: only when a test fails do we have a way to
include the trace.
So let's do something different when using Azure DevOps: let's run all
the tests with `--quiet` first, and only if a failure is encountered,
try to trace the commands as they are executed.
Of course, we cannot turn on `--verbose-log` after the fact. So let's
just re-run the test with all the same options, adding `--verbose-log`.
And then munging the output file into the JUnit XML on the fly.
Note: there is an off chance that re-running the test in verbose mode
"fixes" the failures (and this does happen from time to time!). That is
a possibility we should be able to live with. Ideally, we would label
this as "Passed upon rerun", and Azure Pipelines even know about that
outcome, but it is not available when using the JUnit XML format for
now:

When running the p4 daemon or `git daemon`, we want to kill it at the
end of the test script.
So far, we do this "manually".
However, in the next few commits we want to teach the test suite to
optionally re-run scripts with different options, therefore we will have
to have a consistent way to stop daemons.
Let's introduce `test_atexit`, which is loosely modeled after
`test_when_finished` (but has a broader scope: rather than running the
commands after the current test case, run them when the test script
finishes, and also run them when the `--immediate` option is in effect).

This commit adds an azure-pipelines.yml file which is Azure DevOps'
equivalent to Travis CI's .travis.yml.
To make things a bit easier to understand, we refrain from using the
`matrix` feature here because (while it is powerful) it can be a bit
confusing to users who are not familiar with CI setups. Therefore, we
use a separate phase even for similar configurations (such as GCC vs
Clang on Linux, GCC vs Clang on macOS).
Also, we make use of the shiny new feature we just introduced where the
test suite can output JUnit-style .xml files. This information is made
available in a nice UI that allows the viewer to filter by phase and/or
test number, and to see trends such as: number of (failing) tests, time
spent running the test suite, etc.
