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.

This happens only when the corresponding commits are not exported in
the current fast-export run. This can happen either when the relevant
commit is already marked, or when the commit is explicitly marked
as UNINTERESTING with a negative ref by another argument.
This breaks fast-export basec remote helpers.

Along the lines of 05d0e3b and f33946d, use cat instead of echo to avoid

Again, avoid using echo (which issues DOS line endings on msysGit) to not mix
with Unix line-endings issued by git built-ins, even if this is at the cost of
calling an external executable (cat) instead of a shell built-in (echo).
MSys2 has a slightly different notion of what constitutes a tty than
the Microsoft C runtime. The former knows whether stdin/stdout/stderr
was redirected or not, while the latter looks for a Win32 Console.
In particular when we want to know whether to spawn a pager or not, we
would rather want to know what MSys2 thinks.
We are about to introduce a change to the msys2-runtime that sets an
environment variable MSYS_TTY_HANDLES to a list of Win32 handles that
correspond to stdin/stdout/stderr, respectively, *but skips* handles that
MSys2 does not think are terminals.
This commit handles that input to augment the isatty() function to return
1 also when MSYS_TTY_HANDLES contains the corresponding handle.
The only time when Git needs to know whether a Console is attached or not
is when winansi.c is asked to Do Its Thing, therefore we refrain from
overriding isatty there.
Note: this was an issue with MSys1-based Git for Windows, too, hidden by
the fact that Git for Windows used `cmd.exe` as a terminal -- which is
backed by a real Win32 Console. Had MSys1 used, say, rxvt as its default
terminal, the symptom would have been that "git log" does not spawn a
pager by default but instead outputs the entire history (without color
coding, too). In MSys2, the default terminal is mintty, therefore we
finally could not avoid to address the issue.

On Windows >= Vista, not having an application manifest with a
requestedExecutionLevel can cause several kinds of confusing behavior.
The first and more obvious behavior is "Installer Detection", where
Windows sometimes decides (by looking at things like the file name and
even sequences of bytes within the executable) that an executable is an
installer and should run elevated (causing the well-known popup dialog
to appear). In Git's context, subcommands such as "git patch-id" or "git
update-index" fall prey to this behavior.
The second and more confusing behavior is "File Virtualization". It
means that when files are written without having write permission, it
does not fail (as expected), but they are instead redirected to
somewhere else. When the files are read, the original contents are
returned, though, not the ones that were just written somewhere else.
Even more confusing, not all write accesses are redirected; Trying to
write to write-protected .exe files, for example, will fail instead of
redirecting.
In addition to being unwanted behavior, File Virtualization causes
dramatic slowdowns in Git (see for instance
http://code.google.com/p/msysgit/issues/detail?id=320).
There are two ways to prevent those two behaviors: Either you embed an
application manifest within all your executables, or you add an external
manifest (a file with the same name followed by .manifest) to all your
executables. Since Git's builtins are hardlinked (or copied), it is
simpler and more robust to embed a manifest.
A recent enough MSVC compiler should already embed a working internal
manifest, but for MinGW you have to do so by hand.
Very lightly tested on Wine, where like on Windows XP it should not make
any difference.

processorArchitecture attribute of the manifest's assemblyIdentity
section.]

There is a really useful debugging technique developed by Sverre
Rabbelier that inserts "bash &&" somewhere in the test scripts, letting
the developer interact at given points with the current state.
Another debugging technique, used a lot by this here coder, is to run
certain executables via gdb by guarding a "gdb -args" call in
bin-wrappers/git.
Both techniques were disabled by 781f76b1(test-lib: redirect stdin of
tests).
Let's reinstate the ability to run an interactive shell by making the
redirection optional: setting the TEST_NO_REDIRECT environment variable
will skip the redirection.

With MSys2, there is actually an implementation of mkfifo available. The
only problem is that it is only emulating named pipes through the MSys2
runtime; The Win32 API has no idea about named pipes, hence the Git
executable cannot access those pipes either.
The symptom is that Git fails with a '<name>: No such file or directory'
because MSys2 emulates named pipes through special-crafted '.lnk' files.
The solution is to tell the test suite explicitly that we cannot use
named pipes when we want to test a MinGW Git.

MSys2 actually allows to create files or directories whose names contain
tabs, newlines or colors, even if plain Win32 API cannot access them.
As we are using an MSys2 bash to run the tests, such files or
directories are created successfully, but Git has no chance to work with
them because it is a regular Windows program, hence limited by the Win32
API.

With MSys2, the "TZ" environment variable gets filtered out when calling
non-MSys2 executables. The reason is that Windows' time zone handling is
substantially different from the POSIX one.
However, we just taught Git for Windows' fork of the MSys2 runtime to
pass on the timezone in a different environment variable, MSYS2_TZ for
the sole purpose of Git being able to reinterpret it correctly.

On Windows, we would like to be able to have a default http.sslCAinfo
that points to an MSys path (i.e. relative to the installation root of
Git). As Git is a MinGW program, it has to handle the conversion
of the MSys path into a MinGW32 path itself.
Since system_path() considers paths starting with '/' as absolute, we
have to convince it to make a Windows path by stripping the leading
slash.

Credential Manager, come back as null when reading the credential.
One use case for such empty credentials is with NTLM authentication, where

When locating the relevant credentials, make empty username match null.

On Windows, there are dramatic problems when a command line grows
beyond PATH_MAX, which is restricted to 8191 characters on XP and
later (according to http://support.microsoft.com/kb/830473).
Work around this by just cutting off the command line at that length
(actually, at a space boundary) in the hope that only negative
refs are chucked: gitk will then do unnecessary work, but that is
still better than flashing the gitk window and exiting with exit
status 5 (which no Windows user is able to make sense of).
The first fix caused Tcl to fail to compile the regexp, see msysGit issue
427. Here is another fix without using regexp, and using a more relaxed
command line length limit to fix the original issue 387.
