1e043cff78 t1500: avoid changing working directory outside of tests
Ideally, each test should be responsible for setting up state it needs
rather than relying upon transient global state. Toward this end, teach
test_rev_parse() to accept a "-C <dir>" option to allow callers to
instruct it explicitly in which directory its tests should be run. Take
advantage of this new option to avoid changing the working directory
outside of tests.

Implementation note: test_rev_parse() passes "-C <dir>" along to
git-rev-parse with <dir> properly quoted. The natural and POSIX way to
do so is via ${dir:+-C "$dir"}, however, with some older broken shells,
this expression evaluates incorrectly to a single argument ("-C <dir>")
rather than the expected two (-C and "<dir>"). Work around this problem
with the slightly ungainly expression: ${dir:+-C} ${dir:+"$dir"}

12f7526c66 t1500: test_rev_parse: facilitate future test enhancements
Tests run by test_rev_parse() are nearly identical; each invokes
git-rev-parse with a single option and compares the result against an
expected value. Such duplication makes it onerous to extend the tests
since any change needs to be repeated in each test. Avoid the
duplication by parameterizing the test and driving it via a for-loop.

d66f68ff98 t1500: be considerate to future potential tests
The final batch of git-rev-parse tests work against a non-local object
database named repo.git. This is done by renaming .git to repo.git and
pointing GIT_DIR at it, but the name is never restored to .git at the
end of the script, which can be problematic for tests added in the
future. Be more friendly by instead making repo.git a copy of .git.

Furthermore, make it clear that tests in repo.git will be independent
from the results of earlier tests done in .git by initializing repo.git
earlier in the test sequence.

Likewise, bundle remaining preparation (such as directory creation) into
a common setup test consistent with modern practice.

7bec7f50ae t3404: use write_script
The test uses hardcoded #!/bin/sh to create a pre-commit hook
script.  Because the generated script uses $(command substitution),
which is not supported by /bin/sh on some platforms (e.g. Solaris),
the resulting pre-commit always fails.

Which is not noticeable as the test that uses the hook is about
checking the behaviour of the command when the hook fails ;-), but
nevertheless it is not testing what we wanted to test.

Use write_script so that the resulting script is run under the same
shell our scripted Porcelain commands are run, which must support
the necessary $(construct).

a3bb8ca74c t1020: do not overuse printf and use write_script
The test prepares a sample file "dir/two" with a single incomplete
line in it with "printf", and also prepares a small helper script
"diff" to create a file with a single incomplete line in it, again
with "printf".  The output from the latter is compared with an
expected output, again prepared with "printf" hence lacking the
final LF.  There is no reason for this test to be using files with
an incomplete line at the end, and these look more like a mistake
of not using

	printf "%s\n" "string to be written"

and using

	printf "string to be written"

Depending on what would be in $GIT_PREFIX, using the latter form
could be a bug waiting to happen.  Correct them.

Also, the test uses hardcoded #!/bin/sh to create a small helper
script.  For a small task like what the generated script does, it
does not matter too much in that what appears as /bin/sh would not
be _so_ broken, but while we are at it, use write_script instead,
which happens to make the result easier to read by reducing need
of one level of quoting.

ca386ee177 t5532: use write_script
The recent cleanup in b7cbbff switched t5532's use of
backticks to $(). This matches our normal shell style, which
is good. But it also breaks the test on Solaris, where
/bin/sh does not understand $().

Our normal shell style assumes a modern-ish shell which
knows about $(). However, some tests create small helper
scripts and just write "#!/bin/sh" into them. These scripts
either need to go back to using backticks, or they need to
respect $SHELL_PATH. The easiest way to do the latter is to
use write_script.

While we're at it, let's also stick the script creation
inside a test_expect block (our usual style), and split the
perl snippet into its own script (to prevent quoting
madness).

27014cbc04 commit: do not ignore an empty message given by -m ''
When f9568530 (builtin-commit: resurrect behavior for multiple -m
options, 2007-11-11) converted a "char *message" to "struct strbuf
message" to hold the messages given with the "-m" option, it
incorrectly changed the checks "did we get a message with the -m
option?" to "is message.len 0?".  Later, we noticed one breakage
from this change and corrected it with 25206778 (commit: don't start
editor if empty message is given with -m, 2013-05-25).

However, "we got a message with -m, even though an empty one, so we
shouldn't be launching an editor" was not the only breakage.

 * "git commit --amend -m '' --allow-empty", even though it looks
   strange, is a valid request to amend the commit to have no
   message at all.  Due to the misdetection of the presence of -m on
   the command line, we ended up keeping the log messsage from the
   original commit.

 * "git commit -m "$msg" -F file" should be rejected whether $msg is
   an empty string or not, but due to the same bug, was not rejected
   when $msg is empty.

 * "git -c template=file -m "$msg"" should ignore the template even
   when $msg is empty, but it didn't and instead used the contents
   from the template file.

Correct these by checking have_option_m, which the earlier 25206778
introduced to fix the same bug.

Since commit c4805393 (autocrlf: Make it work also for un-normalized

normalized at commit when core.autocrl is set.

95c38fb0ed branch: fix shortening of non-remote symrefs
Commit aedcb7d (branch.c: use 'ref-filter' APIs, 2015-09-23)
adjusted the symref-printing code to look like this:

    if (item->symref) {
	    skip_prefix(item->symref, "refs/remotes/", &desc);
	    strbuf_addf(&out, " -> %s", desc);
    }

This has three bugs in it:

  1. It always skips past "refs/remotes/", instead of
     skipping past the prefix associated with the branch we
     are showing (so commonly we see "refs/remotes/" for the
     refs/remotes/origin/HEAD symref, but the previous code
     would skip "refs/heads/" when showing a symref it found
     in refs/heads/.

  2. If skip_prefix() does not match, it leaves "desc"
     untouched, and we show whatever happened to be in it
     (which is the refname from a call to skip_prefix()
     earlier in the function).

  3. If we do match with skip_prefix(), we stomp on the
     "desc" variable, which is later passed to
     add_verbose_info(). We probably want to retain the
     original refname there (though it likely doesn't matter
     in practice, since after all, one points to the other).

The fix to match the original code is fairly easy: record
the prefix to strip based on item->kind, and use it here.
However, since we already have a local variable named "prefix",
let's give the two prefixes verbose names so we don't
confuse them.

c6777563cd git-send-pack: fix --all option when used with directory
When using git send-pack with --all option
and a target repository specification ([<host>:]<directory>),
usage message is being displayed instead of performing
the actual transmission.

The reason for this issue is that destination and refspecs are being set
in the same conditional and are populated from argv. When a target
repository is passed, refspecs is being populated as well with its value.
This makes the check for refspecs not being NULL to always return true,
which, in conjunction with the check for --all or --mirror options,
is always true as well and returns usage message instead of proceeding.

This ensures that send-pack will stop execution only when --all
or --mirror switch is used in conjunction with any refspecs passed.

ca4e3ca029 diffcore: fix iteration order of identical files during rename detection
If the two paths 'dir/A/file' and 'dir/B/file' have identical content
and the parent directory is renamed, e.g. 'git mv dir other-dir', then
diffcore reports the following exact renames:

    renamed:    dir/B/file -> other-dir/A/file
    renamed:    dir/A/file -> other-dir/B/file

While technically not wrong, this is confusing not only for the user,
but also for git commands that make decisions based on rename
information, e.g. 'git log --follow other-dir/A/file' follows
'dir/B/file' past the rename.

This behavior is a side effect of commit v2.0.0-rc4~8^2~14
(diffcore-rename.c: simplify finding exact renames, 2013-11-14): the
hashmap storing sources returns entries from the same bucket, i.e.
sources matching the current destination, in LIFO order.  Thus the
iteration first examines 'other-dir/A/file' and 'dir/B/file' and, upon
finding identical content and basename, reports an exact rename.

Other hashmap users are apparently happy with the current iteration
order over the entries of a bucket.  Changing the iteration order
would risk upsetting other hashmap users and would increase the memory
footprint of each bucket by a pointer to the tail element.

Fill the hashmap with source entries in reverse order to restore the
original exact rename detection behavior.

c1e06d11c7 submodule update: test recursive path reporting from subdirectory
This patch is just a test and fixes no bug as there is currently no bug
in the path handling of `submodule update`.

In `submodule update` we make a call to `submodule--helper list --prefix
"$wt_prefix"` which looks a bit brittle and likely to introduce a bug
for the path handling. It is not a bug as the prefix is ignored inside
the submodule helper for now. If this test breaks eventually, we want
to make sure the `wt_prefix` is passed correctly into recursive submodules.
Hint: In recursive submodules we expect `wt_prefix` to be empty.

b08238ac3f submodule update: align reporting path for custom command execution
In the predefined actions (merge, rebase, none, checkout), we use
the display path, which is relative to the current working directory.
Also use the display path when running a custom command.

10450cf72b submodule status: correct path handling in recursive submodules
The new test which is a replica of the previous test except
that it executes from a sub directory. Prior to this patch
the test failed by having too many '../' prefixed:

The path code in question:
  displaypath=$(relative_path "$prefix$sm_path")
  prefix=$displaypath
  if recursive:
    eval cmd_status

That way we change `prefix` each iteration to contain another
'../', because of the the relative_path computation is done
on an already computed relative path.

We must call relative_path exactly once with `wt_prefix` non empty.
Further calls in recursive instances to to calculate the displaypath
already incorporate the correct prefix from before. Fix the issue by
clearing `wt_prefix` in recursive calls.

c1ab00fb26 submodule update --init: correct path handling in recursive submodules
When calling `git submodule init` from a recursive instance of
`git submodule update --recursive`, the reported path is wrong as it
skips the nested submodules.

The new test demonstrates a failure in the code prior to this patch.
Instead of getting the expected
    Submodule 'submodule' (${pwd}/submodule) registered for path '../super/submodule'
the `super` directory is omitted and you get
    Submodule 'submodule' (${pwd}/submodule) registered for path '../submodule'
instead.

ea2fa1040d submodule foreach: correct path display in recursive submodules
The `prefix` was put in front of the display path unconditionally.
This is wrong as any relative path computation would need to be at
the front, so include the prefix into the display path.

The new test replicates the previous test with the difference of executing
from a sub directory. By executing from a sub directory all we would
expect all displayed paths to be prefixed by '../'.

Prior to this patch the test would report
    Entering 'nested1/nested2/../nested3'
instead of the expected
    Entering '../nested1/nested2/nested3'

f292244c04 branch -d: refuse deleting a branch which is currently checked out
When a branch is checked out by current working tree, deleting the
branch is forbidden. However when the branch is checked out only by
other working trees, deleting incorrectly succeeds.
Use find_shared_symref() to check if the branch is in use, not just
comparing with the current working tree's HEAD.

b84e65d409 merge: fix NULL pointer dereference when merging nothing into void
When we are on an unborn branch and merging only one foreign parent,
we allow "git merge" to fast-forward to that foreign parent commit.

This codepath incorrectly attempted to dereference the list of
parents that the merge is going to record even when the list is
empty.  It must refuse to operate instead when there is no parent.

All other codepaths make sure the list is not empty before they
dereference it, and are safe.

8257d3b458 mingw: skip some tests in t9115 due to file name issues
These two tests wanted to write file names which are incompatible with
Windows' file naming rules (even if they pass using Cygwin due to
Cygwin's magic path mangling).

While at it, skip the same tests also on MacOSX/HFS, as pointed out by
Torsten Bögershausen.

45bf32971c t1300: fix the new --show-origin tests on Windows
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).

2ec20212c5 t1300-repo-config: make it resilient to being run via 'sh -x'
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.
