This reverts commit b9a43869c9f96d3577d6f568c1bda1940c8f0e31.
This commit causes breakage on macOS (10.13). It causes errors on
startup and completely breaks the commit functionality. There are two
main problems. First, it uses `string cat` which is not supported on
older Tcl versions. Second, it does a half close of the bidirectional
pipe to git-stripspace which is also not supported on older Tcl
versions.

Although `test -f` has the same functionality as test_path_is_file(), in
the case where test_path_is_file() fails, we get much better debugging
information.
Replace `test -f` with test_path_is_file so that future developers
will have a better experience debugging these test cases.

The following sequence, on a case-insensitive file system,
(strictly speeking with core.ignorecase=true)
leads to an assertion failure and leaves .git/index.lock behind.
git init
echo foo >foo
git add foo
git mv foo FOO
git mv foo bar
This regression was introduced in Commit 9b906af657,
"git-mv: improve error message for conflicted file"
The bugfix is to change the "file exist case-insensitive in the index"
into the correct "file exist (case-sensitive) in the index".
This avoids the "assert" later in the code and keeps setting up the
"ce" pointer for ce_stage(ce) done in the next else if.
This fixes

The approach to "fsck" the incoming objects in "index-pack" is
attractive for performance reasons (we have them already in core,
inflated and ready to be inspected), but fundamentally cannot be
applied fully when we receive more than one pack stream, as a tree
object in one pack may refer to a blob object in another pack as
".gitmodules", when we want to inspect blobs that are used as
".gitmodules" file, for example. Teach "index-pack" to emit
objects that must be inspected later and check them in the calling
"fetch-pack" process.

We've had mixed reports on whether the latest release of macOS needs
this Makefile knob set. In most reported cases, there's antivirus
software running (which one might imagine could cause an open() call to
be delayed). However, one of the (off-list) reports I've gotten
indicated that it happened on an otherwise clean install of Big Sur.
Since the symptom is so bad (checkout randomly fails to write several
fails when the progress meter kicks in), and since the workaround is so
lightweight (if we don't see EINTR, it's just an extra conditional
check), let's just turn it on by default.

The githooks(5) documentation states in several places that the hook
will receive a SHA-1 or hashes of 40 characters length. Given that we're
transitioning to a world where both SHA-1 and SHA-256 are supported,
this is inaccurate.

dir_rename_counts has a mapping of a mapping, in particular, it has
old_dir => { new_dir => count }
We want a simple mapping of
old_dir => new_dir
based on which new_dir had the highest count for a given old_dir.
Compute this and store it in dir_rename_guess.
This is the final piece of the puzzle needed to make our guesses at
which directory files have been moved to when basenames aren't unique.
For the testcases mentioned in commit 557ac0350d ("merge-ort: begin
performance work; instrument with trace2_region_* calls", 2020-10-28),
this change improves the performance as follows:
Before After

We are using dir_rename_counts to count the number of other directories
that files within a directory moved to. We only need this information
for directories that disappeared, though, so we can return early from
update_dir_rename_counts() for other paths.
If dirs_removed is passed to diffcore_rename_extended(), then it
provides the relevant bits of information for us to limit this counting
to relevant dirs. If dirs_removed is not passed, we would need to
compute some replacement in order to do this limiting. Introduce a new
info->relevant_source_dirs variable for this purpose, even though at
this stage we will only set it to dirs_removed for simplicity.

Compute dir_rename_counts based just on exact renames to start, as that
can provide us useful information in find_basename_matches(). This is
done by moving the code from compute_dir_rename_counts() into
initialize_dir_rename_info(), resulting in it being computed earlier and
based just on exact renames. Since that's an incomplete result, we
augment the counts via calling update_dir_rename_counts() after each
basename-guide and inexact rename detection match is found.

When diffcore_rename_extended() is passed a NULL dir_rename_count, we
will still want to create a temporary one for use by
find_basename_matches(), but have it fully deallocated before
diffcore_rename_extended() returns. However, when
diffcore_rename_extended() is passed a dir_rename_count, we want to fill
that strmap with appropriate values and return it. However, for our
interim purposes we may also add entries corresponding to directories
that cannot have been renamed due to still existing on both sides.
Extend cleanup_dir_rename_info() to handle these two different cases,
cleaning up the relevant bits of information for each case.

Move the computation of dir_rename_count from merge-ort.c to
diffcore-rename.c, making slight adjustments to the data structures
based on the move. While the diffstat looks large, viewing this commit
with --color-moved makes it clear that only about 20 lines changed.
With this patch, the computation of dir_rename_count is still only done
after inexact rename detection, but subsequent commits will add a
preliminary computation of dir_rename_count after exact rename
detection, followed by some updates after inexact rename detection.

A previous commit noted that it is very common for people to move files
across directories while keeping their filename the same. The last few
commits took advantage of this and showed that we can accelerate rename
detection significantly using basenames; since files with the same
basename serve as likely rename candidates, we can check those first and
remove them from the rename candidate pool if they are sufficiently
similar.
Unfortunately, the previous optimization was limited by the fact that
the remaining basenames after exact rename detection are not always
unique. Many repositories have hundreds of build files with the same
name (e.g. Makefile, .gitignore, build.gradle, etc.), and may even have
hundreds of source files with the same name. (For example, the linux
kernel has 100 setup.c, 87 irq.c, and 112 core.c files. A repository at
$DAYJOB has a lot of ObjectFactory.java and Plugin.java files).
For these files with non-unique basenames, we are faced with the task of
attempting to determine or guess which directory they may have been
relocated to. Such a task is precisely the job of directory rename
detection. However, there are two catches: (1) the directory rename
detection code has traditionally been part of the merge machinery rather
than diffcore-rename.c, and (2) directory rename detection currently
runs after regular rename detection is complete. The 1st catch is just
an implementation issue that can be overcome by some code shuffling.
The 2nd requires us to add a further approximation: we only have access
to exact renames at this point, so we need to do directory rename
detection based on just exact renames. In some cases we won't have
exact renames, in which case this extra optimization won't apply. We
also choose to not apply the optimization unless we know that the
underlying directory was removed, which will require extra data to be
passed in to diffcore_rename_extended(). Also, even if we get a
prediction about which directory a file may have relocated to, we will
still need to check to see if there is a file in the predicted
directory, and then compare the two files to see if they meet the higher
min_basename_score threshold required for marking the two files as
renames.
This commit introduces an idx_possible_rename() function which will
do this directory rename detection for us and give us the index within
rename_dst of the resulting filename. For now, this function is
hardcoded to return -1 (not found) and just hooks up how its results
would be used once we have a more complete implementation in place.

When opening a reverse index, load_revindex_from_disk() jumps to the
'cleanup' label in case something goes wrong: the reverse index had the
wrong size, an unrecognized version, or similar.
It also jumps to this label when the reverse index couldn't be opened in
the first place, which will cause an error with the unguarded close()
call in the label.
Guard this call with "if (fd >= 0)" to make sure that we have a valid
file descriptor to close before attempting to close it.

When running the perf suite, we copy files from an existing $GIT_DIR to
a scratch repository to give us a realistic setup on which to operate.
Since the perf scripts themselves may modify the scratch repository, we
want to make sure we've scrubbed any references back to the original.
One existing example is that we avoid copying the file "commondir" at
the top-level of the repository. In a worktree git-dir (e.g.,
.git/worktrees/foo), that file contains the path to the parent
repository; copying it could mean ref updates in the scratch repository
affect the original.
But there are other files we should cover, too:
- "gitdir" in a worktree git-dir contains the path to the actual .git
file in the working tree. We _shouldn't_ end up looking at it at
all, since the lack of a "commondir" file means Git won't consider
this to be a worktree git-dir. But it's best to err on the safe
side.
- in a parent repository that contains worktrees, the
"$GIT_DIR/worktrees" directory will contain the git dirs for the
individual worktrees. Which will themselves contain commondir and
gitdir files that may reference the original repository. We should
likewise remove them.
Note that this does mean that the perf suite's scratch repositories
will never have any worktrees. That's OK; we don't have any perf tests
that are influenced by their presence. If we add any, they'd
probably want to create the worktrees themselves anyway.
This patch adds both paths to the set of omissions in
test_perf_copy_repo_contents(). Note that we won't get confused here by
matching arbitrary names like refs/heads/commondir. This list is always
matching top-level entries in $GIT_DIR (we rely on "cp -R" to do the
actual recursion).
