When constructing command-lines to spawn processes, it is an unfortunate
but necessary decision to quote arguments differently: MSYS2 has
different dequoting rules (inherited from Cygwin) than the rest of
Windows.
To accommodate that, Git's Windows compatibility layer has two separate
quoting helpers, one for MSYS2 (which it uses exclusively when spawning
`sh`) and the other for regular Windows executables.
The MSYS2 one had an unfortunate bug where a `,` somehow slipped in,
instead of the `;`. As a consequence, empty arguments would not be
enclosed in a pair of double quotes, but the closing double quote was
skipped.
Let's fix this.

At the point where `mingw_spawn_fd()` is called, we already have a full
path to the script interpreter in that scenario, and we pass it in as
the executable to run, while the `argv` reflect what the script should
receive as command-line.

While the only permitted drive letters for physical drives on Windows
are letters of the US-English alphabet, this restriction does not apply
to virtual drives assigned via `subst <letter>: <path>`.
To prevent targeted attacks against systems where "funny" drive letters
such as `1` or `!` are assigned, let's handle them as regular drive
letters on Windows.
This fixes CVE-2019-1351.

On Windows, filenames cannot have trailing spaces or periods, when
opening such paths, they are stripped automatically. Read: you can open
the file `README` via the file name `README . . .`. This ambiguity can
be used in combination with other security bugs to cause e.g. remote
code execution during recursive clones. This patch series fixes that.

Over a decade ago, in 25fe217b86c (Windows: Treat Windows style path
names., 2008-03-05), Git was taught to handle absolute Windows paths,
i.e. paths that start with a drive letter and a colon.
Unbeknownst to us, while drive letters of physical drives are limited to
letters of the English alphabet, there is a way to assign virtual drive
letters to arbitrary directories, via the `subst` command, which is
_not_ limited to English letters.
It is therefore possible to have absolute Windows paths of the form
`1:\what\the\hex.txt`. Even "better": pretty much arbitrary Unicode
letters can also be used, e.g. `ä:\tschibät.sch`.
While it can be sensibly argued that users who set up such funny drive
letters really seek adverse consequences, the Windows Operating System
is known to be a platform where many users are at the mercy of
administrators who have their very own idea of what constitutes a
reasonable setup.
Therefore, let's just make sure that such funny paths are still
considered absolute paths by Git, on Windows.
In addition to Unicode characters, pretty much any character is a valid
drive letter, as far as `subst` is concerned, even `:` and `"` or even a
space character. While it is probably the opposite of smart to use them,
let's safeguard `is_dos_drive_prefix()` against all of them.
Note: `[::1]:repo` is a valid URL, but not a valid path on Windows.
As `[` is now considered a valid drive letter, we need to be very
careful to avoid misinterpreting such a string as valid local path in
`url_is_local_not_ssh()`. To do that, we use the just-introduced
function `is_valid_path()` (which will label the string as invalid file
name because of the colon characters).
This fixes CVE-2019-1351.

When creating a directory on Windows whose path ends in a space or a
period (or chains thereof), the Win32 API "helpfully" trims those. For
example, `mkdir("abc ");` will return success, but actually create a
directory called `abc` instead.
This stems back to the DOS days, when all file names had exactly 8
characters plus exactly 3 characters for the file extension, and the
only way to have shorter names was by padding with spaces.
Sadly, this "helpful" behavior is a bit inconsistent: after a successful
`mkdir("abc ");`, a `mkdir("abc /def")` will actually _fail_ (because
the directory `abc ` does not actually exist).
Even if it would work, we now have a serious problem because a Git
repository could contain directories `abc` and `abc `, and on Windows,
they would be "merged" unintentionally.
As these paths are illegal on Windows, anyway, let's disallow any
accesses to such paths on that Operating System.
For practical reasons, this behavior is still guarded by the
config setting `core.protectNTFS`: it is possible (and at least two
regression tests make use of it) to create commits without involving the
worktree. In such a scenario, it is of course possible -- even on
Windows -- to create such file names.
Among other consequences, this patch disallows submodules' paths to end
in spaces on Windows (which would formerly have confused Git enough to
try to write into incorrect paths, anyway).
While this patch does not fix a vulnerability on its own, it prevents an
attack vector that was exploited in demonstrations of a number of
recently-fixed security bugs.
The regression test added to `t/t7417-submodule-path-url.sh` reflects
that attack vector.
Note that we have to adjust the test case "prevent git~1 squatting on
Windows" in `t/t7415-submodule-names.sh` because of a very subtle issue.
It tries to clone two submodules whose names differ only in a trailing
period character, and as a consequence their git directories differ in
the same way. Previously, when Git tried to clone the second submodule,
it thought that the git directory already existed (because on Windows,
when you create a directory with the name `b.` it actually creates `b`),
but with this patch, the first submodule's clone will fail because of
the illegal name of the git directory. Therefore, when cloning the
second submodule, Git will take a different code path: a fresh clone
(without an existing git directory). Both code paths fail to clone the
second submodule, both because the the corresponding worktree directory
exists and is not empty, but the error messages are worded differently.

Certain characters are not admissible in file names on Windows, even if
Cygwin/MSYS2 (and therefore, Git for Windows' Bash) pretend that they
are, e.g. `:`, `<`, `>`, etc
Let's disallow those characters explicitly in Windows builds of Git.
Note: just like trailing spaces or periods, it _is_ possible on Windows
to create commits adding files with such illegal characters, as long as
the operation leaves the worktree untouched. To allow for that, we
continue to guard `is_valid_win32_path()` behind the config setting
`core.protectNTFS`, so that users _can_ continue to do that, as long as
they turn the protections off via that config setting.
Among other problems, this prevents Git from trying to write to an "NTFS
Alternate Data Stream" (which refers to metadata stored alongside a
file, under a special name: "<filename>:<stream-name>"). This fix
therefore also prevents an attack vector that was exploited in
demonstrations of a number of recently-fixed security bugs.

We need to be careful to follow proper quoting rules. For example, if an
argument contains spaces, we have to quote them. Double-quotes need to
be escaped. Backslashes need to be escaped, but only if they are
followed by a double-quote character.
We need to be _extra_ careful to consider the case where an argument
ends in a backslash _and_ needs to be quoted: in this case, we append a
double-quote character, i.e. the backslash now has to be escaped!
The current code, however, fails to recognize that, and therefore can
turn an argument that ends in a single backslash into a quoted argument
that now ends in an escaped double-quote character. This allows
subsequent command-line parameters to be split and part of them being
mistaken for command-line options, e.g. through a maliciously-crafted
submodule URL during a recursive clone.
Technically, we would not need to quote _all_ arguments which end in a
backslash _unless_ the argument needs to be quoted anyway. For example,
`test\` would not need to be quoted, while `test \` would need to be.
To keep the code simple, however, and therefore easier to reason about
and ensure its correctness, we now _always_ quote an argument that ends
in a backslash.
This addresses CVE-2019-1350.

The return value of that function is 0 both for variables that are
unset, as well as for variables whose values are empty. To discern those
two cases, one has to call `GetLastError()`, whose return value is
`ERROR_ENVVAR_NOT_FOUND` and `ERROR_SUCCESS`, respectively.
Except that it is not actually set to `ERROR_SUCCESS` in the latter
case, apparently, but the last error value seems to be simply unchanged.
To work around this, let's just re-set the last error value just before
inspecting the environment variable.
This fixes a problem that triggers failures in t3301-notes.sh (where we
try to override config settings by passing empty values for certain
environment variables).
This problem is hidden in the MINGW build by the fact that older
MSVC runtimes (such as the one used by MINGW builds) have a `calloc()`
that re-sets the last error value in case of success, while newer
runtimes set the error value only if `NULL` is returned by that
function.

To build with MSVC, we "translate" GCC options to MSVC options, and part
of those options refer to the libraries to link into the final
executable. Currently, this part looks somewhat like this on Windows:
-lcurl -lnghttp2 -lidn2 -lssl -lcrypto -lssl -lcrypto -lgdi32
-lcrypt32 -lwldap32 -lz -lws2_32 -lexpat
Some of those are direct dependencies (such as curl and ssl) and others
are indirect (nghttp2 and idn2, for example, are dependencies of curl,
but need to be linked in for reasons).
We already handle the direct dependencies, e.g. `-liconv` is already
handled as adding `libiconv.lib` to the list of libraries to link
against.
Let's just ignore the remaining `-l*` options so that MSVC does not have
to warn us that it ignored e.g. the `/lnghttp2` option. We do that by
extending the clause that already "eats" the `-R*` options to also eat
the `-l*` options.

The `qsort()` function is not guaranteed to be stable, i.e. it does not
promise to maintain the order of items it is told to consider equal. In
contrast, the `git_sort()` function we carry in `compat/qsort.c` _is_
stable, by virtue of implementing a merge sort algorithm.
In preparation for using a stable sort in Git's rename detection, move
the stable sort into `libgit.a` so that it is compiled in
unconditionally, and rename it to `git_stable_qsort()`.
Note: this also makes the hack obsolete that was introduced in
fe21c6b285d (mingw: reencode environment variables on the fly (UTF-16
<-> UTF-8), 2018-10-30), where we included `compat/qsort.c` directly in
`compat/mingw.c` to use the stable sort.

compat/*.[ch]: remove extern from function declarations using spatch

In 554544276a (*.[ch]: remove extern from function declarations using
spatch, 2019-04-29), we removed externs from function declarations using
spatch but we intentionally excluded files under compat/ since some are
directly copied from an upstream and we should avoid churning them so
that manually merging future updates will be simpler.
In the last commit, we determined the files which taken from an upstream
so we can exclude them and run spatch on the remainder.
This was the Coccinelle patch used:
@@
type T;
identifier f;
@@
- extern
T f(...);
and it was run with:
$ git ls-files compat/\*\*.{c,h} |
xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place
$ git checkout -- \
compat/regex/ \
compat/inet_ntop.c \

compat/obstack.{c,h} \
compat/poll/
Coccinelle has some trouble dealing with `__attribute__` and varargs so
we ran the following to ensure that no remaining changes were left
behind:
$ git ls-files compat/\*\*.{c,h} |
xargs sed -i'' -e 's/^\(\s*\)extern \([^(]*([^*]\)/\1\2/'

If Git were installed in a path containing non-ASCII characters,
commands such as `git am` and `git submodule`, which are implemented as
externals, would fail to launch with the following error:
> fatal: 'am' appears to be a git command, but we were not
> able to execute it. Maybe git-am is broken?
This was due to lookup_prog not being Unicode-aware. It was somehow
missed in 85faec9d3a (Win32: Unicode file name support (except dirent),
2012-03-15).
Note that the only problem in this function was calling
`GetFileAttributes()` instead of `GetFileAttributesW()`. The calls to
`access()` were fine because `access()` is a macro which resolves to
`mingw_access()`, which already handles Unicode correctly. But
`lookup_prog()` was changed to use `_waccess()` directly so that we only
convert the path to UTF-16 once.
To make things work correctly, we have to maintain UTF-8 and UTF-16
versions in tandem in `lookup_prog()`.

Cast the evaluated value of the macro INITIAL_LOCK to void to instruct
the compiler that we're not interested in said value nor the following

Support building Git with Visual Studio
The bits about .git/branches/* have been dropped from the series.
We may want to drop the support for it, but until that happens, the
tests should rely on the existence of the support to pass.
* js/visual-studio: (23 commits)
git: avoid calling aliased builtins via their dashed form
bin-wrappers: append `.exe` to target paths if necessary
.gitignore: ignore Visual Studio's temporary/generated files
.gitignore: touch up the entries regarding Visual Studio
vcxproj: also link-or-copy builtins
msvc: add a Makefile target to pre-generate the Visual Studio solution
contrib/buildsystems: add a backend for modern Visual Studio versions
contrib/buildsystems: handle options starting with a slash
contrib/buildsystems: also handle -lexpat
contrib/buildsystems: handle libiconv, too
contrib/buildsystems: handle the curl library option
contrib/buildsystems: error out on unknown option
contrib/buildsystems: optionally capture the dry-run in a file
contrib/buildsystems: redirect errors of the dry run into a log file
contrib/buildsystems: ignore gettext stuff
contrib/buildsystems: handle quoted spaces in filenames
contrib/buildsystems: fix misleading error message
contrib/buildsystems: ignore irrelevant files in Generators/
contrib/buildsystems: ignore invalidcontinue.obj
Vcproj.pm: urlencode '<' and '>' when generating VC projects

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.
If we pre-generate the Visual Studio solution, Git can be built entirely
within Visual Studio, and the test scripts can be run in a regular Git
for Windows (e.g. the Portable Git flavor, which does not include a full
GCC toolchain and therefore weighs only about a tenth of 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 after building the solution in Visual Studio.
Note: for this build target, we do not actually need to initialize the
`vcpkg` system, so we don't.

On some older Windows versions (e.g. Windows 7), the CreateProcessW()
function does not really support spaces in its first argument,
lpApplicationName. But it supports passing NULL as lpApplicationName,
which makes it figure out the application from the (possibly quoted)
first argument of lpCommandLine.
Let's use that trick (if we are certain that the first argument matches
the executable's path) to support launching programs whose path contains
spaces.
We will abuse the test-fake-ssh.exe helper to verify that this works and
does not regress.
This fixes https://github.com/git-for-windows/git/issues/692
