Replace the hard-coded SHA-1 constants with the use of test_oid to look
up an appropriate constant for each hash algorithm. In addition, adjust
the fanout checks to look for either zero or one slashes in the filename
without needing to check for an explicit length.

Ever since df56607dff (git-common-dir: make "modules/"
per-working-directory directory, 2014-11-30), submodules in linked worktrees
are cloned to $GIT_DIR/modules, i.e. $GIT_COMMON_DIR/worktrees/<name>/modules.
However, this convention was not followed when the worktree updater commands
checkout, reset and read-tree learned to recurse into submodules. Specifically,
submodule.c::submodule_move_head, introduced in 6e3c1595c6 (update submodules:
add submodule_move_head, 2017-03-14) and submodule.c::submodule_unset_core_worktree,
(re)introduced in 898c2e65b7 (submodule: unset core.worktree if no working tree
is present, 2018-12-14) use get_git_common_dir() instead of get_git_dir()
to get the path of the submodule repository.
This means that, for example, 'git checkout --recurse-submodules <branch>'
in a linked worktree will correctly checkout <branch>, detach the submodule's HEAD
at the commit recorded in <branch> and update the submodule working tree, but the
submodule HEAD that will be moved is the one in $GIT_COMMON_DIR/modules/<name>/,
i.e. the submodule repository of the main superproject working tree.
It will also rewrite the gitfile in the submodule working tree of the linked worktree
to point to $GIT_COMMON_DIR/modules/<name>/.
This leads to an incorrect (and confusing!) state in the submodule working tree
of the main superproject worktree.
Additionally, if switching to a commit where the submodule is not present,
submodule_unset_core_worktree will be called and will incorrectly remove
'core.wortree' from the config file of the submodule in the main superproject worktree,
$GIT_COMMON_DIR/modules/<name>/config.
Fix this by constructing the path to the submodule repository using get_git_dir()
in both submodule_move_head and submodule_unset_core_worktree.

When 'checkout --to' functionality was moved to 'worktree add', tests were adapted
in f194b1ef6e (tests: worktree: retrofit "checkout --to" tests for "worktree add",
2015-07-06).
The calls were changed to 'worktree add' in this test (then t7410), but the test
descriptions were not updated, keeping 'checkout' instead of using the new
terminology (linked worktrees).
Also, in the test each worktree is created in
$TRASH_DIRECTORY/<leading-directory>/main, where the name of <leading-directory>
carries some information about what behavior each test verifies. This directory
structure is not mandatory for the tests; the worktrees can live next to one
another in the trash directory.
Clarify the tests by using the right terminology, and remove the unnecessary
leading directories such that all superproject worktrees are directly next to one
another in the trash directory.

To prevent long blocking time during a 'git fetch' call, a user
may want to set up a schedule for background 'git fetch' processes.
However, these runs will update the refs/remotes branches due to
the default refspec set in the config when Git adds a remote.
Hence the user will not notice when remote refs are updated during
their foreground fetches. In fact, they may _want_ those refs to
stay put so they can work with the refs from their last foreground
fetch call.
This can be accomplished by overriding the configured refspec using
'--refmap=' along with a custom refspec:
git fetch --refmap='' <remote> +refs/heads/*:refs/hidden/<remote>/*
to populate a custom ref space and download a pack of the new
reachable objects. This kind of call allows a few things to happen:
1. We download a new pack if refs have updated.
2. Since the refs/hidden branches exist, GC will not remove the
newly-downloaded data.
3. With fetch.writeCommitGraph enabled, the refs/hidden refs are
used to update the commit-graph file.
To avoid the refs/hidden directory from filling without bound, the
--prune option can be included. When providing a refspec like this,
the --prune option does not delete remote refs and instead only
deletes refs in the target refspace.
Update the documentation to clarify how '--refmap=""' works and
create tests to guarantee this behavior remains in the future.

A test in t7800 tries to make sure that when git-difftool runs an
external tool that fails, it stops looking at files. Our fake failing
tool prints the file name it was asked to diff before exiting non-zero,
and then we confirm the output contains only that file.
However, this subtly relies on our internal reuse_worktree_file().
Because we're diffing between branches, the command run by difftool
might see:
- the git-stored filename (e.g., "file"), if we decided that the
working tree contents were up-to-date with the object in the index
and HEAD, and we could reuse them
- a temporary filename (e.g. "/tmp/abc123_file") if we had to dump the
contents from the object database
If the latter case happens, then the test fails, because it's expecting
the string "file". I discovered this when debugging something unrelated
with reuse_worktree_file(). I _thought_ it should be able to be
triggered by a racy-git situation, but running:
./t7800-difftool.sh --stress --run=2,13
never seems to fail. However, by my reading of reuse_worktree_file(),
this would probably always fail under Cygwin, because it sets
NO_FAST_WORKING_DIRECTORY. At any rate, since reuse_worktree_file()
is meant to be an optimization that may or may not trigger, our test
should be robust either way.
Instead of checking the filename, let's just make sure we got a single
line of output (which would not be true if we continued after the first
failure).

We run a series of hunk-header tests in a loop, and each one does this:
test_when_finished 'cat actual' && # for debugging only
This is pretty pointless. When the test succeeds, we waste time running
a useless cat process. If you're debugging a failure with "-i", then we
won't run the when-finished part at all. So it helps only if you're
running with something like "--verbose-log".
Since we expect the tests to succeed most of the time, a better way to
do this would be a helper that checks the output and dumps "actual" only
when it fails. But it's probably not even worth the effort, as anyone
debugging a failure could just run with "-i" and investigate the
"actual" file themselves.

The interactive `add` command allows selecting multiple files for some
of its sub-commands, via unique prefixes, indices or index ranges.
When re-implementing `git add -i` in C, we even added a code comment
talking about ranges with a missing end index, such as `2-`, but the
code did not actually accept those, as pointed out in
https://github.com/git-for-windows/git/issues/2466#issuecomment-574142760.
Let's fix this, and add a test case to verify that this stays fixed

I was going to title this "dir: more synchronizing of
treat_leading_path() and read_directory_recursive()", a nod to commit
777b42034764 ("dir: synchronize treat_leading_path() and
read_directory_recursive()", 2019-12-19), but the title was too long.
Anyway, first the backstory...
fill_directory() has always had a slightly error-prone interface: it
returns a subset of paths which *might* match the specified pathspec; it
was intended to prune away some paths which didn't match the specified
pathspec and keep at least all the ones that did match it. Given this
interface, callers were responsible to post-process the results and
check whether each actually matched the pathspec.
builtin/clean.c did this. It would first prune out duplicates (e.g. if
"dir" was returned as well as all files under "dir/", then it would
simplify this to just "dir"), and after pruning duplicates it would
compare the remaining paths to the specified pathspec(s). This
post-processing itself could run into problems, though, as noted in
commit 404ebceda01c ("dir: also check directories for matching
pathspecs", 2019-09-17):
For the case of git-clean and a set of pathspecs of "dir/file" and
"more", this caused a problem because we'd end up with dir entries
for both of
"dir"
"dir/file"
Then correct_untracked_entries() would try to helpfully prune
duplicates for us by removing "dir/file" since it's under "dir",
leaving us with
"dir"
Since the original pathspec only had "dir/file", the only entry left
doesn't match and leaves nothing to be removed. (Note that if only
one pathspec was specified, e.g. only "dir/file", then the
common_prefix_len optimizations in fill_directory would cause us to
bypass this problem, making it appear in simple tests that we could
correctly remove manually specified pathspecs.)
That commit fixed the issue -- when multiple pathspecs were specified --
by making sure fill_directory() wouldn't return both "dir" and
"dir/file" outside the common_prefix_len optimization path. This is
where it starts to get fun.
In commit b9670c1f5e6b ("dir: fix checks on common prefix directory",
2019-12-19), we noticed that the common_prefix_len wasn't doing
appropriate checks and letting all kinds of stuff through, resulting in
recursing into .git/ directories and other craziness. So it started
locking down and doing checks on pathnames within that code path. That
continued with commit 777b42034764 ("dir: synchronize
treat_leading_path() and read_directory_recursive()", 2019-12-19), which
noted the following:
Our optimization to avoid calling into read_directory_recursive()
when all pathspecs have a common leading directory mean that we need
to match the logic that read_directory_recursive() would use if we
had just called it from the root. Since it does more than call
treat_path() we need to copy that same logic.
...and then it more forcefully addressed the issue with this wonderfully
ironic statement:
Needing to duplicate logic like this means it is guaranteed someone
will eventually need to make further changes and forget to update
both locations. It is tempting to just nuke the leading_directory
special casing to avoid such bugs and simplify the code, but
unpack_trees' verify_clean_subdirectory() also calls
read_directory() and does so with a non-empty leading path, so I'm
hesitant to try to restructure further. Add obnoxious warnings to
treat_leading_path() and read_directory_recursive() to try to warn
people of such problems.
You would think that with such a strongly worded description, that its
author would have actually ensured that the logic in
treat_leading_path() and read_directory_recursive() did actually match
and that *everything* that was needed had at least been copied over at
the time that this paragraph was written. But you'd be wrong, I messed
it up by missing part of the logic.
Copy the missing bits to fix the new final test in t7300.

b9670c1f5e (dir: fix checks on common prefix directory, 2019-12-19)
modified the way pathspecs are handled when handling a directory
during "git clean -f <path>". While this improved the behavior for
known test breakages, it also regressed in how the clean command
handles cleaning a specified file.
Add a test case that demonstrates this behavior. This test passes
before b9670c1f5e then fails after.

To make our values hash independent, we turn the directory of the object
into "Y" and the file name into "Z" after having sorted items by their
name. However, when using SHA-256, one of our file names begins with an
"a" character, which means it sorts into the wrong place in the list,
causing the test to fail.
Since we don't care about the order of these items, just sort them after
stripping actual hash contents, which means they'll work with any hash
algorithm.

When using SHA-1, the existing value of the byte we use is 0x13, so
writing the byte 0x07 serves to corrupt the test and verify that we
detect corruption. However, when we use SHA-256, the value at that
offset is already 0x07, so our "corruption" doesn't work and the test
fails to detect it.
To provide a value that is truly out of range, let's use 0xff, which is
not likely to be a valid value as the high byte of a two-byte offset in
a multi-pack index this small.
