When cloning a repo with a --filter and with --recurse-submodules
enabled, the partial clone filter only applies to the top-level repo.
This can lead to unexpected bandwidth and disk usage for projects which
include large submodules. For example, a user might wish to make a
partial clone of Gerrit and would run:
`git clone --recurse-submodules --filter=blob:5k https://gerrit.googlesource.com/gerrit`.
However, only the superproject would be a partial clone; all the
submodules would have all blobs downloaded regardless of their size.
With this change, the same filter can also be applied to submodules,
meaning the expected bandwidth and disk savings apply consistently.
To avoid changing default behavior, add a new clone flag,
`--also-filter-submodules`. When this is set along with `--filter` and
`--recurse-submodules`, the filter spec is passed along to git-submodule
and git-submodule--helper, such that submodule clones also have the
filter applied.
This applies the same filter to the superproject and all submodules.
Users who need to customize the filter per-submodule would need to clone
with `--no-recurse-submodules` and then manually initialize each
submodule with the proper filter.
Applying filters to submodules should be safe thanks to Jonathan Tan's
recent work [1, 2, 3] eliminating the use of alternates as a method of
accessing submodule objects, so any submodule object access now triggers
a lazy fetch from the submodule's promisor remote if the accessed object
is missing. This patch is a reworked version of [4], which was created
prior to Jonathan Tan's work.

When trying to write a MIDX, we already prevent the case where there
weren't any packs present, and thus we would have written an empty MIDX.
But there is another "empty" case, which is more interesting, and we
don't yet handle. If we try to write a MIDX which has at least one pack,
but those packs together don't contain any objects, we will encounter a
BUG() when trying to use the bitmap corresponding to that MIDX, like so:
$ git rev-parse HEAD | git pack-objects --revs --use-bitmap-index --stdout >/dev/null
BUG: pack-revindex.c:394: pack_pos_to_midx: out-of-bounds object at 0
(note that in the above reproduction, both `--use-bitmap-index` and
`--stdout` are important, since without the former we won't even both to
load the .bitmap, and without the latter we wont attempt pack reuse).
The problem occurs when we try to discover the identity of the
preferred pack to determine which range if any of existing packs we can
reuse verbatim. This path is: `reuse_packfile_objects()` ->
`reuse_partial_packfile_from_bitmap()` -> `midx_preferred_pack()`.
#4 0x000055555575401f in pack_pos_to_midx (m=0x555555997160, pos=0) at pack-revindex.c:394
#5 0x00005555557502c8 in midx_preferred_pack (bitmap_git=0x55555599c280) at pack-bitmap.c:1431
#6 0x000055555575036c in reuse_partial_packfile_from_bitmap (bitmap_git=0x55555599c280, packfile_out=0x5555559666b0 <reuse_packfile>,
entries=0x5555559666b8 <reuse_packfile_objects>, reuse_out=0x5555559666c0 <reuse_packfile_bitmap>) at pack-bitmap.c:1452
#7 0x00005555556041f6 in get_object_list_from_bitmap (revs=0x7fffffffcbf0) at builtin/pack-objects.c:3658
#8 0x000055555560465c in get_object_list (ac=2, av=0x555555997050) at builtin/pack-objects.c:3765
#9 0x0000555555605e4e in cmd_pack_objects (argc=0, argv=0x7fffffffe920, prefix=0x0) at builtin/pack-objects.c:4154
Since neither the .bitmap or MIDX stores the identity of the
preferred pack, we infer it by trying to load the first object in
pseudo-pack order, and then asking the MIDX which pack was chosen to
represent that object.
But this fails our bounds check, since there are zero objects in the
MIDX to begin with, which results in the BUG().
We could catch this more carefully in `midx_preferred_pack()`, but
signaling the absence of a preferred pack out to all of its callers is
somewhat awkward.
Instead, let's avoid writing a MIDX .bitmap without any objects
altogether. We catch this case in `write_midx_internal()`, and emit a
warning if the caller indicated they wanted to write a bitmap before
clearing out the relevant flags. If we somehow got to
write_midx_bitmap(), then we will call BUG(), but this should now be an
unreachable path.

Update the __gitcomp_directories method to de-quote and handle unusual
characters in directory names. Although this initially involved an attempt
to re-use the logic in __git_index_files, this method removed
subdirectories (e.g. folder1/0/ became folder1/), so instead new custom
logic was placed directly in the __gitcomp_directories method.
Note there are two tests for this new functionality - one for spaces and
accents and one for backslashes and tabs. The backslashes and tabs test
uses FUNNYNAMES to avoid running on Windows. This is because:
1. Backslashes are explicitly not allowed in Windows file paths.
2. Although tabs appear to be allowed when creating a file in a Windows
bash shell, they actually are not renderable (and appear as empty boxes
in the shell).

Correct multiple issues with tab completion of the git sparse-checkout
command. These issues were:
1. git sparse-checkout <TAB> previously resulted in an incomplete list of
subcommands (it was missing reapply and add).
2. Subcommand options were not tab-completable.
3. git sparse-checkout set <TAB> and git sparse-checkout add <TAB> showed
both file names and directory names. While this may be a less surprising
behavior for non-cone mode, cone mode sparse checkouts should complete
only directory names.
Note that while the new strategy of just using git ls-tree to complete on
directory names is simple and a step in the right direction, it does have
some caveats. These are:
1. Likelihood of poor performance in large monorepos (as a result of
recursively completing directory names).
2. Inability to handle paths containing unusual characters.
These caveats will be fixed by subsequent commits in this series.

When we taught these commands about the sparse index, we did not account
for the fact that the `cmd_*()` functions _can_ be called without a
gitdir, namely when `-h` is passed to show the usage.
A plausible approach to address this is to move the
`prepare_repo_settings()` calls right after the `parse_options()` calls:
The latter will never return when it handles `-h`, and therefore it is
safe to assume that we have a `gitdir` at that point, as long as the
built-in is marked with the `RUN_SETUP` flag.
However, it is unfortunately not that simple. In `cmd_pack_objects()`,
for example, the repo settings need to be fully populated so that the
command-line options `--sparse`/`--no-sparse` can override them, not the
other way round.
Therefore, we choose to imitate the strategy taken in `cmd_diff()`,
where we simply do not bother to prepare and initialize the repo
settings unless we have a `gitdir`.

When adding a new worktree, it is reasonable to expect that we want to
use the current set of sparse-checkout settings for that new worktree.
This is particularly important for repositories where the worktree would
become too large to be useful. This is even more important when using
partial clone as well, since we want to avoid downloading the missing
blobs for files that should not be written to the new worktree.
The only way to create such a worktree without this intermediate step of
expanding the full worktree is to copy the sparse-checkout patterns and
config settings during 'git worktree add'. Each worktree has its own
sparse-checkout patterns, and the default behavior when the
sparse-checkout file is missing is to include all paths at HEAD. Thus,
we need to have patterns from somewhere, they might as well be the
current worktree's patterns. These are then modified independently in
the future.
In addition to the sparse-checkout file, copy the worktree config file
if worktree config is enabled and the file exists. This will copy over
any important settings to ensure the new worktree behaves the same as
the current one. The only exception we must continue to make is that
core.bare and core.worktree should become unset in the worktree's config
file.

`git sparse-checkout set/init` enables worktree-specific
configuration[*] by setting extensions.worktreeConfig=true, but neglects
to perform the additional necessary bookkeeping of relocating
`core.bare=true` and `core.worktree` from $GIT_COMMON_DIR/config to
$GIT_COMMON_DIR/config.worktree, as documented in git-worktree.txt. As a
result of this oversight, these settings, which are nonsensical for
secondary worktrees, can cause Git commands to incorrectly consider a
worktree bare (in the case of `core.bare`) or operate on the wrong
worktree (in the case of `core.worktree`). Fix this problem by taking
advantage of the recently-added init_worktree_config() which enables
`extensions.worktreeConfig` and takes care of necessary bookkeeping.
While at it, for backward-compatibility reasons, also stop upgrading the
repository format to "1" since doing so is (unintentionally) not
required to take advantage of `extensions.worktreeConfig`, as explained
by 11664196ac ("Revert "check_repository_format_gently(): refuse
extensions for old repositories"", 2020-07-15).
[*] The main reason to use worktree-specific config for the
sparse-checkout builtin was to avoid enabling sparse-checkout patterns
in one and causing a loss of files in another. If a worktree does not
have a sparse-checkout patterns file, then the sparse-checkout logic
will not kick in on that worktree.

Upgrading a repository to use extensions.worktreeConfig is non-trivial.
There are several steps involved, including moving some config settings
from the common config file to the main worktree's config.worktree file.
The previous change updated the documentation with all of these details.
Commands such as 'git sparse-checkout set' upgrade the repository to use
extensions.worktreeConfig without following these steps, causing some
user pain in some special cases.
Create a helper method, init_worktree_config(), that will be used in a
later change to fix this behavior within 'git sparse-checkout set'. The
method is carefully documented in worktree.h.
Note that we do _not_ upgrade the repository format version to 1 during

and third-party tools even if core.repositoryFormatVersion is 0 for
historical reasons documented in 11664196ac ("Revert

To improve the submodules UX, we would like to teach Git to handle
branches in submodules. Start this process by teaching "git branch" the
--recurse-submodules option so that "git branch --recurse-submodules
topic" will create the `topic` branch in the superproject and its
submodules.
Although this commit does not introduce breaking changes, it does not
work well with existing --recurse-submodules commands because "git
branch --recurse-submodules" writes to the submodule ref store, but most
commands only consider the superproject gitlink and ignore the submodule
ref store. For example, "git checkout --recurse-submodules" will check
out the commits in the superproject gitlinks (and put the submodules in
detached HEAD) instead of checking out the submodule branches.
Because of this, this commit introduces a new configuration value,
`submodule.propagateBranches`. The plan is for Git commands to
prioritize submodule ref store information over superproject gitlinks if
this value is true. Because "git branch --recurse-submodules" writes to
submodule ref stores, for the sake of clarity, it will not function
unless this configuration value is set.
This commit also includes changes that support working with submodules
from a superproject commit because "branch --recurse-submodules" (and
future commands) need to read .gitmodules and gitlinks from the
superproject commit, but submodules are typically read from the
filesystem's .gitmodules and the index's gitlinks. These changes are:
* add a submodules_of_tree() helper that gives the relevant
information of an in-tree submodule (e.g. path and oid) and
initializes the repository
* add is_tree_submodule_active() by adding a treeish_name parameter to
is_submodule_active()
* add the "submoduleNotUpdated" advice to advise users to update the
submodules in their trees
Incidentally, fix an incorrect usage string that combined the 'list'
usage of git branch (-l) with the 'create' usage; this string has been
incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use
parse_options., 2007-10-07).

Fix a bug that's been here since 7cc8f97108 (pack-objects: implement
bitmap writing, 2013-12-21), we did not call stop_progress() if we
reached the early exit in this function.
We could call stop_progress() before we return, but better yet is to
defer calling start_progress() until we need it. For now this only
matters in practice because we'd previously omit the "region_leave"
for the progress trace2 event.
