MSys works very hard to convert Unix-style paths into DOS-style ones.
*Very* hard.
So hard, indeed, that
git blame -L/hello/,/green/
is translated into something like
git blame -LC:/msysgit/hello/,C:/msysgit/green/
As seen in msys_p2w in src\msys\msys\rt\src\winsup\cygwin\path.cc, line
3204ff:
case '-':
//
// here we check for POSIX paths as attributes to a POSIX switch.
//
...
seemingly absolute POSIX paths in single-letter options get expanded by
msys.dll unless they contain '=' or ';'.
So a quick and very dirty fix is to use '-L/;*evil/'. (Using an equal sign
works only when it is before a comma, so in the above example, /=*green/
would still be converted to a DOS-style path.)

The test separator char is a colon which means any absolute paths on windows
confuse the tests that use global_excludes.

Apparently the signal handling is not quite correct in the fsckobject
handling (most likely we rely on a side effect that lets us still output
some message after receiving a signal 13 but in the BuildHive setup this
fails intermittently).
As a consequence, the push in t5504 does fail as expected, but fails to
output anything (unexpected). Since this is good enough for now, let's
handle an empty output as success, too.

Actually, we should always keep the trailing slashes as both users of
`normalize_ntpath()` require them: `_wchdir()` wants the slash in
particular when changing the directory to a drive root, and
`readlink()`'s semantics require a trailing slash for symbolic links
pointing to directories.

This is needed so that `_wchdir()` can be used with drive root
directories, e.g. C:\ (`_wchdir("C:")` fails to switch the directory
to the root directory).

The idea of `git-bash.exe` automatically running the Git Bash in the
home directory was to support the start menu item `Git Bash` (which
should not start in C:\Program Files\Git, but in $HOME), and to make
that behavior consistent with double-clicking in `git-bash.exe`
portable Git.
However, it turns out that one of the main use cases of portable Git is
to run the Git Bash in GitHub for Windows, and it should start in the
top-level directory of a given project. Therefore, the concern to keep
double-clicking `git-bash.exe` consistent with the start menu item was
actually unfounded.
As to the start menu item: it can easily be changed to launch
`git-bash.exe` with a command-line option. So let's introduce the
--cd-to-home option for that purpose.
As a bonus, the Git wrapper can now also serve as a drop-in redirector
/bin/bash.exe to provide backwards-compatibility of Git for Windows 2.x
with 1.x: some 3rd-party software expects to find that executable there,
and it also expects it to leave the working directory unchanged.

This branch introduces support for reading the "Windows-wide" Git
configuration from `%PROGRAMDATA%\Git\config`. As these settings are
intended to be shared between *all* Git-related software, that config
file takes an even lower precedence than `$(prefix)/etc/gitconfig`.

Between the libgit2 and the Git for Windows project, there has been a
discussion how we could share Git configuration to avoid duplication (or
worse: skew).
Earlier, libgit2 was nice enough to just re-use Git for Windows'
C:\Program Files (x86)\Git\etc\gitconfig
but with the upcoming Git for Windows 2.x, there would be more paths to
search, as we will have 64-bit and 32-bit versions, and the
corresponding config files will be in %PROGRAMFILES%\Git\mingw64\etc and
...\mingw32\etc, respectively.
Worse: there are portable Git for Windows versions out there which live
in totally unrelated directories, still.
Therefore we came to a consensus to use `%PROGRAMDATA%\Git\config` as the
location for shared Git settings that are of wider interest than just Git
for Windows.
On XP, there is no %PROGRAMDATA%, therefore we need to use
"%ALLUSERSPROFILE%\Application Data\Git\config" in those setups.
Of course, the configuration in `%PROGRAMDATA%\Git\config` has the
widest reach, therefore it must take the lowest precedence, i.e. Git for
Windows can still override settings in its `etc/gitconfig` file.

By embedding string resources into the Git wrapper executable, it
can be configured to execute custom commands (after setting up the
environment in the way required for Git for Windows to work properly).
This feature is used e.g. for `git-bash.exe` which launches a Bash in
the configured terminal window.
Here, we introduce command-line options to override those string
resources. That way, a user can call `git-bash.exe` (which is a copy of
the Git wrapper with `usr\bin\bash.exe --login -i` embedded as string
resource) with command-line options that will override what command is
run.
ConEmu, for example, might want to call
...\git-bash.exe --needs-console --no-hide --minimal-search-path ^
--command=usr\\bin\\bash.exe --login -i
In particular, the following options are supported now:
--command=<command-line>::
Executes `<command-line>` instead of the embedded string resource
--[no-]minimal-search-path::
Ensures that only `/cmd/` is added to the `PATH` instead of
`/mingw??/bin` and `/usr/bin/`, or not
--[no-]needs-console::
Ensures that there is a Win32 console associated with the spawned
process, or not
--[no-]hide::
Hides the console window, or not

files. However, it fails with a misleading error message "could not lock

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:

Use msysGit's `git-wrapper` instead of the builtins. This works around
two issues:
- when the file system does not allow hard links, we would waste over
800 megabyte by having 109 copies of a multi-megabyte executable
- even when the file system allows hard links, the Windows Explorer
counts the disk usage as if it did not. Many users complained about
Git for Windows using too much space (when it actually did not). We
can easily avoid those user complaints by merging this branch.
