Always check out the required commit at the beginning of the test so
that a failure in a previous test does not cause the test to work off
of the wrong commit.
This is a step toward making the tests more independent so that if one
test fails it doesn't cause subsequent tests to fail.

Create and use a test-specific branch when the test might create a
commit. This is not always necessary for correctness, but it improves
debuggability by ensuring a commit created by test #N shows up on the
testN branch, not the branch for test #N-1.

If the repository must be in a particular state (beyond what is
already done by the 'setup' test case) before the test can run, make
the necessary repository changes in the test script even if it means
duplicating some lines of code from the previous test case.

The "--" argument avoids "ambiguous argument: unknown revision or

The "--" passed explicitly to set was removed because rev-parse

When you hit ^C to interrupt a git command going to a pager,
this usually leaves the pager running. But when a dashed
external is in use, the pager ends up in a funny state and
quits (but only after eating one more character from the
terminal!). This fixes it.
Explaining the reason will require a little background.
When git runs a pager, it's important for the git process to
hang around and wait for the pager to finish, even though it
has no more data to feed it. This is because git spawns the
pager as a child, and thus the git process is the session
leader on the terminal. After it dies, the pager will finish
its current read from the terminal (eating the one
character), and then get EIO trying to read again.
When you hit ^C, that sends SIGINT to git and to the pager,
and it's a similar situation. The pager ignores it, but the
git process needs to hang around until the pager is done. We
addressed that long ago in a3da882120 (pager: do
wait_for_pager on signal death, 2009-01-22).
But when you have a dashed external (or an alias pointing to
a builtin, which will re-exec git for the builtin), there's
an extra process in the mix. For instance, running:
$ git -c alias.l=log l
will end up with a process tree like:
git (parent)
\
git-log (child)
\
less (pager)
If you hit ^C, SIGINT goes to all of them. The pager ignores
it, and the child git process will end up in wait_for_pager().
But the parent git process will die, and the usual EIO
trouble happens.
So we really want the parent git process to wait_for_pager(),
but of course it doesn't know anything about the pager at
all, since it was started by the child. However, we can
have it wait on the git-log child, which in turn is waiting
on the pager. And that's what this patch does.
There are a few design decisions here worth explaining:
1. The new feature is attached to run-command's
clean_on_exit feature. Partly this is convenience,
since that feature already has a signal handler that
deals with child cleanup.
But it's also a meaningful connection. The main reason
that dashed externals use clean_on_exit is to bind the
two processes together. If somebody kills the parent
with a signal, we propagate that to the child (in this
instance with SIGINT, we do propagate but it doesn't
matter because the original signal went to the whole
process group). Likewise, we do not want the parent
to go away until the child has done so.
In a traditional Unix world, we'd probably accomplish
this binding by just having the parent execve() the
child directly. But since that doesn't work on Windows,
everything goes through run_command's more spawn-like
interface.
2. We do _not_ automatically waitpid() on any
clean_on_exit children. For dashed externals this makes
sense; we know that the parent is doing nothing but
waiting for the child to exit anyway. But with other
children, it's possible that the child, after getting
the signal, could be waiting on the parent to do
something (like closing a descriptor). If we were to
wait on such a child, we'd end up in a deadlock. So
this errs on the side of caution, and lets callers
enable the feature explicitly.
3. When we send children the cleanup signal, we send all
the signals first, before waiting on any children. This
is to avoid the case where one child might be waiting
on another one to exit, causing a deadlock. We inform
all of them that it's time to die before reaping any.
In practice, there is only ever one dashed external run
from a given process, so this doesn't matter much now.
But it future-proofs us if other callers start using
the wait_after_clean mechanism.
There's no automated test here, because it would end up racy
and unportable. But it's easy to reproduce the situation by
running the log command given above and hitting ^C.

When we try to exec a git sub-command, we pass along the
status code from run_command(). But that may return -1 if we
ran into an error with pipe() or execve(). This tends to
work (and end up as 255 due to twos-complement wraparound
and truncation), but in general it's probably a good idea to
avoid negative exit codes for portability.
We can easily translate to the normal generic "128" code we
get when syscalls cause us to die.

When we run a dashed external, we use the one-liner
run_command_v_opt() to do so. Let's switch to using a
child_process struct, which has two advantages:
1. We can drop all of the allocation and cleanup code for
building our custom argv array, and just rely on the
builtin argv_array (at the minor cost of doing a few
extra mallocs).
2. We have access to the complete range of child_process
options, not just the ones that the "_opt()" form can
forward.

Every once in a while someone complains to the mailing list to have
run into this weird assertion[1]. The usual response from the mailing
list is link to old discussions[2], and acknowledging the problem
stating it is known.
This patch accomplishes two things:
1. Switch assert() to die("BUG") to give a more readable message.
2. Take one of the cases where we hit a BUG and turn it into a normal
"there was something wrong with the input" message.
This assertion triggered for cases where there wasn't a programming
bug, but just bogus input. In particular, if the user asks for a
pathspec that is inside a submodule, we shouldn't assert() or
die("BUG"); we should tell the user their request is bogus.
The only reason we did not check for it, is the expensive nature
of such a check, so callers avoid setting the flag
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE. However when we die due
to bogus input, the expense of CPU cycles spent outweighs the user
wondering what went wrong, so run that check unconditionally before
dying with a more generic error message.
Note: There is a case (e.g. "git -C submodule add .") in which we call
strip_submodule_slash_expensive, as git-add requests it via the flag
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE, but the assert used to
trigger nevertheless, because the flag PATHSPEC_LITERAL was not set,
such that we executed
if (item->nowildcard_len < prefixlen)
item->nowildcard_len = prefixlen;
and prefixlen was not adapted (e.g. it was computed from "submodule/")
So in the die_inside_submodule_path function we also need handle paths,
that were stripped before, i.e. are the exact submodule path. This
is why the conditions in die_inside_submodule_path are slightly
different than in strip_submodule_slash_expensive.

The logic used to prefix an original pathspec element with 'prefix'
magic is more general purpose and can be used for more than just short
magic. Remove the extra code paths and rename 'prefix_short_magic' to
'prefix_magic' to better indicate that it can be used in more general
situations.
Also, slightly change the logic which decides when to prefix the
original element in order to prevent a pathspec of "." from getting
converted to "" (empty string).

For better clarity, always show the mnemonic and name of the unsupported
magic being used. This lets users have a more clear understanding of
what magic feature isn't supported. And if they supplied a mnemonic,
the user will be told what its corresponding name is which will allow
them to more easily search the man pages for that magic type.
This also avoids passing an extra parameter around the pathspec
initialization code.

The 'original' string entry in a pathspec_item is only duplicated some
of the time, instead always make a copy of the original and take
ownership of the memory.
Since both 'match' and 'original' string entries in a pathspec_item are
owned by the pathspec struct, they need to be freed when clearing the
pathspec struct (in 'clear_pathspec()') and duplicated when copying the
pathspec struct (in 'copy_pathspec()').
Also change the type of 'match' and 'original' to 'char *' in order to
more explicitly show the ownership of the memory.

Now that all callers of the old 'get_pathspec' interface have been
migrated to use the new pathspec struct interface it can be removed
from the codebase.
Since there are no more users of the '_raw' field in the pathspec struct
it can also be removed. This patch also removes the old functionality
of modifying the const char **argv array that was passed into
parse_pathspec. Instead the constructed 'match' string (which is a
pathspec element with the prefix prepended) is only stored in its
corresponding pathspec_item entry.

instead of using the deprecated 'get_pathspec()' interface. Also,
rename 'internal_copy_pathspec()' to 'internal_prefix_pathspec()' to be

In addition to this, fix a memory leak caused by only duplicating some
of the pathspec elements. Instead always duplicate all of the the
pathspec elements as an intermediate step (with modificationed based on
the passed in flags). This way the intermediate strings can then be
freed after getting the result from 'prefix_path()'.

On Windows, there are "UNC paths" to access network (AKA shared)
folders, of the form \\server\sharename\directory. This provides a
convenient way for Windows developers to share their Git repositories
without having to have a dedicated server.
Git for Windows v2.11.0 introduced a regression where pushing to said
UNC paths no longer works, although fetching and cloning still does, as
reported here: https://github.com/git-for-windows/git/issues/979
This regression was fixed in 7814fbe3f1 (normalize_path_copy(): fix
pushing to //server/share/dir on Windows, 2016-12-14).
Let's make sure that it does not regress again, by introducing a test
that uses so-called "administrative shares": disk volumes are
automatically shared under certain circumstances, e.g. the C: drive is
shared as \\localhost\c$. The test needs to be skipped if the current
directory is inaccessible via said administrative share, of course.
