At some stage, t5003-archive-zip wants to add a file that is not ASCII.
To that end, it uses /bin/sh. But that file may actually not exist (it
is too easy to forget that not all the world is Unix/Linux...)! Besides,
we already have perfectly fine binary files intended for use solely by
the tests. So let's use one of them instead.

Everybody and their dogs, cats and other pets settled on using unified
diffs. It is a really quaint holdover from a long-gone era that GNU diff
outputs "normal" diff by default.
Yet, t4124 relied on that mode.
This mode is so out of fashion in the meantime, though, that e.g.
BusyBox' diff decided not even to bother to support it. It only supports
unified diffs.
So let's just switch away from "normal" diffs and use unified diffs, as
we really are only interested in the `+` lines.

On Windows, it is impossible to create a file whose name contains a
quote character. We already excluded test cases using such files from
running on Windows when git.exe itself was tested.
However, we still had two test cases that try to create such a file, and
redirect stdin from such a file, respectively. This *seems* to work in
Git for Windows' Bash due to an obscure feature inherited from Cygwin:
illegal filename characters are simply mapped into/from a private UTF-8
page. Pure Win32 programs (such as git.exe) *still* cannot work with
those files, of course, but at least Unix shell scripts pretend to be
able to.
This entire strategy breaks down when switching to any Unix shell
lacking support for that private UTF-8 page trick, e.g. BusyBox-w32's
ash. So let's just exclude test cases that test whether the Unix shell
can redirect to/from files with "funny names" those from running on
Windows, too.

Since c6b0831c9c (docs: warn about possible '=' in clean/smudge filter
process values, 2016-12-03), t0021 writes out a file with quotes in its
name, and MSYS2's path conversion heuristics mistakes that to mean that
we are not talking about a path here.
Therefore, we need to use Windows paths, as the test-helper is a Win32
program that would otherwise have no idea where to look for the file.

The -W option is only understood by MSYS2 Bash's pwd command. We already

Traditionally, Git for Windows' SDK uses Bash as its default shell.
However, other Unix shells are available, too. Most notably, the Win32
port of BusyBox comes with `ash` whose `pwd` command already prints
Windows paths as Git for Windows wants them, while there is not even a
`builtin` command.
Therefore, let's be careful not to override `pwd` unless we know that
the `builtin` command is available.

BusyBox-w32 is a true Win32 application, i.e. it does not come with a
POSIX emulation layer.
That also means that it does *not* use the Unix convention of separating
the entries in the PATH variable using colons, but semicolons.
However, there are also BusyBox ports to Windows which use a POSIX
emulation layer such as Cygwin's or MSYS2's runtime, i.e. using colons
as PATH separators.
As a tell-tale, let's use the presence of semicolons in the PATH
variable: on Unix, it is highly unlikely that it contains semicolons,
and on Windows (without POSIX emulation), it is virtually guaranteed, as
everybody should have both $SYSTEMROOT and $SYSTEMROOT/system32 in their
PATH.

It is convenient to assume that everybody who wants to build & test Git
has access to a working `iconv` executable (after all, we already pretty
much require libiconv)
However, that limits esoteric test scenarios such as Git for Windows',
where an end user installation has to ship with `iconv` for the sole
purpose of being testable. That payload serves no other purpose.
So let's just have a test helper (to be able to test Git, the test
helpers have to be available, after all) to act as `iconv` replacement.

This helper is slightly more performant than the script with MSYS2's

To accommodate t1050, which wants to compare files weighing in with 3MB

allocation limit by setting the environment variable GIT_ALLOC_LIMIT to
zero when calling the helper.

It is a bit strange, and even undesirable, to require Perl just to run

This patch does not fix this problem by any stretch of imagination.
However, it fixes *the* Perl invocation that *every single* test script
has to run.
While at it, it makes the source code also more grep'able, as the code

Instead of relying on the presence of `make`, or `prove`, we might just
as well use our own facilities to run the test suite.
This helps e.g. when trying to verify a Git for Windows installation
without requiring to download a full Git for Windows SDK (which would use
up 600+ megabytes of bandwidth, and over a gigabyte of disk space).
Of course, it still requires the test helpers to be build *somewhere*,
and the Git version should at least roughly match the version from which
the test suite comes.
At the same time, this new way to run the test suite allows to validate
that a BusyBox-backed MinGit works as expected (verifying that BusyBox'
functionality is enough to at least pass the test suite).

The MSYS2 runtime does its best to emulate the command-line wildcard
expansion and de-quoting which would be performed by the calling Unix
shell on Unix systems.
Those Unix shell quoting rules differ from the quoting rules applying to
Windows' cmd and Powershell, making it a little awkward to quote
command-line parameters properly when spawning other processes.
In particular, git.exe passes arguments to subprocesses that are *not*
intended to be interpreted as wildcards, and if they contain
backslashes, those are not to be interpreted as escape characters, e.g.
when passing Windows paths.
Note: this is only a problem when calling MSYS2 executables, not when
calling MINGW executables such as git.exe. However, we do call MSYS2
executables frequently, most notably when setting the use_shell flag in
the child_process structure.
There is no elegant way to determine whether the .exe file to be
executed is an MSYS2 program or a MINGW one. But since the use case of
passing a command line through the shell is so prevalent, we need to
work around this issue at least when executing sh.exe.
Let's introduce an ugly, hard-coded test whether argv[0] is "sh", and
whether it refers to the MSYS2 Bash, to determine whether we need to
quote the arguments differently than usual.
That still does not fix the issue completely, but at least it is
something.
Incidentally, this also fixes the problem where `git clone \\server\repo`
failed due to incorrect handling of the backslashes when handing the path
to the git-upload-pack process.
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Due to a quirk in Git's method to spawn git-upload-pack, there is a
problem when passing paths with backslashes in them: Git will force the
command-line through the shell, which has different quoting semantics in
Git for Windows (being an MSYS2 program) than regular Win32 executables
such as git.exe itself.
The symptom is that the first of the two backslashes in UNC paths of the
form \\myserver\folder\repository.git is *stripped off*.
Document this bug by introducing a test case.

On Windows, there are several categories of absolute paths. One such
category starts with a backslash and is implicitly relative to the
drive associated with the current working directory. Example:
c:
git clone https://github.com/git-for-windows/git \G4W
should clone into C:\G4W.
There is currently a problem with that, in that mingw_mktemp() does not
expect the _wmktemp() function to prefix the absolute path with the
drive prefix, and as a consequence, the resulting path does not fit into
the originally-passed string buffer. The symptom is a "Result too large"
error.

With the recent update in efee955 (gpg-interface: check gpg signature
creation status, 2016-06-17), we ask GPG to send all status updates to
stderr, and then catch the stderr in an strbuf.
But GPG might fail, and send error messages to stderr. And we simply
do not show them to the user.
Even worse: this swallows any interactive prompt for a passphrase. And
detaches stderr from the tty so that the passphrase cannot be read.
So while the first problem could be fixed (by printing the captured
stderr upon error), the second problem cannot be easily fixed, and
presents a major regression.

Just like with other Git commands, this option makes it read the paths
from the standard input. It comes in handy when resetting many, many
paths at once and wildcards are not an option (e.g. when the paths are
generated by a tool).
Note: we first parse the entire list and perform the actual reset action
only in a second phase. Not only does this make things simpler, it also
helps performance, as do_diff_cache() traverses the index and the
(sorted) pathspecs in simultaneously to avoid unnecessary lookups.

This is a brown paper bag. When adding the tests, we actually failed

When a third-party tool periodically runs `git status` in order to keep
track of the state of the working tree, it is a bad idea to lock the
index: it might interfere with interactive commands executed by the
user, e.g. when the user wants to commit files.
Git for Windows introduced the `--no-lock-index` option a long time ago
to fix that (it made it into Git for Windows v2.9.2(3)) by simply
avoiding to write that file.
The downside is that the periodic `git status` calls will be a little
bit more wasteful because they may have to refresh the index repeatedly,
only to throw away the updates when it exits. This cannot really be
helped, though, as tools wanting to get a periodic update of the status
have no way to predict when the user may want to lock the index herself.
Sadly, a competing approach was submitted (by somebody who apparently
has less work on their plate than this maintainer) that made it into
v2.15.0 but is *different*: instead of a `git status`-only option, it is
an option that comes *before* the Git command and is called differently,
too.
Let's give previous users a chance to upgrade to newer Git for Windows
versions by handling the `--no-lock-index` option, still, though with a
big fat warning.
