59db7c0ff0 tests: move test PNGs into t/diff-lib/
We already have a directory where we store files intended for use by
multiple test scripts. The same directory is a better home for the
test-binary-*.png files than t/.

54d70bf229 tests: use t/diff-lib/* consistently
The idea of copying README and COPYING into t/diff-lib/ was to step away
from using files from outside t/ in tests. Let's really make sure that
we use the files from t/diff-lib/ instead of other versions of those
files.

afbb18562d test-helper: learn to act as a drop-in replacement for iconv
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.

4ce2d7728c tests: replace mingw_test_cmp with a helper in C
This helper is slightly more performant than the script with MSYS2's
Bash. And a lot more readable.

To accommodate t1050, which wants to compare files weighing in with 3MB
(falling outside of t1050's malloc limit of 1.5MB), we simply lift the
allocation limit by setting the environment variable GIT_ALLOC_LIMIT to
zero when calling the helper.

bd3016ff2c test-lib: avoid unnecessary Perl invocation
It is a bit strange, and even undesirable, to require Perl just to run
the test suite even when NO_PERL was set.

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
that unsets some, but not all, GIT_* environment variables just became a
*lot* more explicit. And all that while still reducing the total number
of lines.

8c1706e594 test-run-command: learn to run (parts of) the testsuite
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).

62462cb541 mingw: special-case arguments to sh
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.

9b3eac5e11 mingw (t5580): document bug when cloning from backslashed UNC paths
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.

5dd1f3ee26 mingw: demonstrate a problem with certain absolute paths
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.

Just like the workaround we added for t9116, t9001.83 hangs sometimes --

The issue seems to be related to redirection via a pipe, but it is really

script (which is executed by an MSYS2 Perl), piping into another MSYS2
program.

As hunting time is scarce these days, simply work around this for now and

77159394a4 Merge branch 'visual-studio'

requiring a Git for Windows SDK), e.g. by running

41d7d04a44 Unbreak interactive GPG prompt upon signing
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.

So let's just revert commit efee9553a4.

af0117a8b4 reset: support the experimental --stdin option
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 feature is marked experimental because it is still under review in
the upstream Git project.

478b1e04b8 status: carry the --no-lock-index option for backwards-compatibility
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.
