On Windows, we have that funny situation where the test script can refer
to POSIX paths because it runs in a shell that uses a POSIX emulation
layer ("MSYS2 runtime"). Yet, git.exe does *not* understand POSIX paths
at all but only pure Windows paths.
So let's just convert the POSIX paths to Windows paths before passing
them on to Git, using `pwd` (which is already modified on Windows to
output Windows paths).
While fixing the new tests on Windows, we also have to exclude the tests
that want to write a file with a name that is illegal on Windows
(unfortunately, there is more than one test trying to make use of that
file).

One way to diagnose broken regression tests is to run the test
script using 'sh -x t... -i -v' to find out which call actually
demonstrates the symptom.
Hence it is pretty counterproductive if the test script behaves
differently when being run via 'sh -x', in particular when using
test_cmp or test_i18ncmp on redirected stderr. A more recent way
"sh tXXXX -i -v -x" has the same issue.
So let's use test_i18ngrep (as suggested by Jonathan Nieder) instead of
test_cmp/test_i18ncmp to verify that stderr looks as expected.

This regression was introduced in 74703a1e4d (submodule: rewrite
`module_list` shell function in C, 2015-09-02), as we changed the
order of checking in new module listing to first check whether it is
a gitlin before feeding it to match_pathspec(). It used to be that
a pathspec that does not match any path were diagnosed as an error,
but the new code complains for a pathspec that does not match any
submodule path.
Arguably the new behaviour may give us a better diagnosis, but that
is inconsistent with the suggestion "deinit" gives, and also this
was an unintended accident. The new behaviour hopefully can be
redesigned and implemented better in future releases, but for now,
switch these two checks to restore the same behavior as before. In
an empty repository, giving the pathspec '.' will still get the same
"did not match" error, but that is the same bug we had before 1.7.0.

We set GIT_CONFIG_NOSYSTEM in our test scripts so that we do
not accidentally read /etc/gitconfig and have it influence
the outcome of the tests. But when running smart-http tests,
Apache will clean the environment, including this variable,
and the "server" side of our http operations will read it.
You can see this breakage by doing something like:
make
./git config --system http.getanyfile false
make test
which will cause t5561 to fail when it tests the
fallback-to-dumb operation.
We can fix this by instructing Apache to pass through the
variable. Unlike with other variables (e.g., 89c57ab3's
GIT_TRACE), we don't need to set a dummy value to prevent
warnings from Apache. test-lib.sh already makes sure that
GIT_CONFIG_NOSYSTEM is set and exported.

According to the documentation, full URLs can be specified in the `-T`
argument to `git svn init`. However, the canonicalization of such

breaks http://, svn://, etc URLs. Add a failing test case to provide
evidence of that.
On systems where Subversion provides svn_path_canonicalize but not

It would have been less work to rename t56* => t57* because there are less

If we are running "git grep --no-index" outside of a git
repository, we behave roughly like "grep -r", examining all
files in the current directory and its subdirectories.
However, because we use fill_directory() to do the
recursion, it will skip over any directories which look like
sub-repositories.
For a normal git operation (like "git grep" in a repository)
this makes sense; we do not want to cross the boundary out
of our current repository into a submodule. But for
"--no-index" without a repository, we should look at all
files, including embedded repositories.
There is one exception, though: we probably should _not_
descend into ".git" directories. Doing so is inefficient and
unlikely to turn up useful hits.
This patch drops our use of dir.c's gitlink-detection, but
we do still avoid ".git". That makes us more like tools such
as "ack" or "ag", which also know to avoid cruft in .git.
As a bonus, this also drops our usage of the ref code
when we are outside of a repository, making the transition
to pluggable ref backends cleaner.

Commit a60645f (setup: remember whether repository was
found, 2010-08-05) introduced the startup_info structure,
which records some parts of the setup_git_directory()
process (notably, whether we actually found a repository or
not).
One of the uses of this data is for functions to behave
appropriately based on whether we are in a repo. But the
startup_info struct is just a pointer to storage provided by
the main program, and the only program that sets it up is
the git.c wrapper. Thus builtins have access to
startup_info, but externally linked programs do not.
Worse, library code which is accessible from both has to be
careful about accessing startup_info. This can be used to
trigger a die("BUG") via get_sha1():
$ git fast-import <<-\EOF
tag foo
from HEAD:./whatever
EOF
fatal: BUG: startup_info struct is not initialized.
Obviously that's fairly nonsensical input to feed to
fast-import, but we should never hit a die("BUG"). And there
may be other ways to trigger it if other non-builtins
resolve sha1s.
So let's point the storage for startup_info to a static
variable in setup.c, making it available to all users of the
library code. We _could_ turn startup_info into a regular
extern struct, but doing so would mean tweaking all of the
existing use sites. So let's leave the pointer indirection
in place. We can, however, drop any checks for NULL, as
they will always be false (and likewise, we can drop the
test covering this case, which was a rather artificial
situation using one of the test-* programs).

Commit 0cc30e0 (strbuf_getwholeline: use getdelim if it is
available, 2015-04-16) tries to clean up after getdelim()
returns EOF, but gets one case wrong, which can lead in some
obscure cases to us reading uninitialized memory.
After getdelim() returns -1, we re-initialize the strbuf
only if sb->buf is NULL. The thinking was that either:
1. We fed an existing allocated buffer to getdelim(), and
at most it would have realloc'd, leaving our NUL in
place.
2. We didn't have a buffer to feed, so we gave getdelim()
NULL; sb->buf will remain NULL, and we just want to
restore the empty slopbuf.
But that second case isn't quite right. getdelim() may
allocate a buffer, write nothing into it, and then return
EOF. The resulting strbuf rightfully has sb->len set to "0",
but is missing the NUL terminator in the first byte.
Most call-sites are fine with this. They see the EOF and
don't bother looking at the strbuf. Or they notice that
sb->len is empty, and don't look at the contents. But
there's at least one case that does neither, and relies on
parsing the resulting (possibly zero-length) string:
fast-import. You can see this in action with the new test
(though we probably only notice failure there when run with
--valgrind or ASAN).
We can fix this by unconditionally resetting the strbuf when
we have a buffer after getdelim(). That fixes case 2 above.
Case 1 is probably already fine in practice, but it does not
hurt for us to re-assert our invariants (especially because
we are relying on whatever getdelim() happens to do, which
may vary from platform to platform). Our fix covers that
case, too.
