b15207b8cf unpack-trees: unpack new trees as sparse directories
If 'unpack_single_entry()' is unpacking a new directory tree (that is, one
not already present in the index) into a sparse index, unpack the tree as a
sparse directory rather than traversing its contents and unpacking each file
individually. This helps keep the sparse index as collapsed as possible in
cases such as 'git reset --hard' restoring a outside-of-cone directory
removed with 'git rm -r --sparse'.

Without this patch, 'unpack_single_entry()' will only unpack a directory
into the index as a sparse directory (rather than traversing into it and
unpacking its files one-by-one) if an entry with the same name already
exists in the index. This patch allows sparse directory unpacking without a
matching index entry when the following conditions are met:

1. the directory's path is outside the sparse cone, and
2. there are no children of the directory in the index

If a directory meets these requirements (as determined by
'is_new_sparse_dir()'), 'unpack_single_entry()' unpacks the sparse directory
index entry and propagates the decision back up to 'unpack_callback()' to
prevent unnecessary tree traversal into the unpacked directory.

9553aa0f6c cache.h: create 'index_name_pos_sparse()'
Add 'index_name_pos_sparse()', which behaves the same as 'index_name_pos()',
except that it does not expand a sparse index to search for an entry inside
a sparse directory.

'index_entry_exists()' was originally implemented in 20ec2d034c (reset: make
sparse-aware (except --mixed), 2021-11-29) as an alternative to
'index_name_pos()' to allow callers to search for an index entry without
expanding a sparse index. However, that particular use case only required
knowing whether the requested entry existed, so 'index_entry_exists()' does
not return the index positioning information provided by 'index_name_pos()'.

This patch implements 'index_name_pos_sparse()' to accommodate callers that
need the positioning information of 'index_name_pos()', but do not want to
expand the index.

56d8a27124 oneway_diff: handle removed sparse directories
Update 'do_oneway_diff()' to perform a 'diff_tree_oid()' on removed sparse
directories, as it does for added or modified sparse directories (see
9eb00af562 (diff-lib: handle index diffs with sparse dirs, 2021-07-14)).

At the moment, this update is unreachable code because 'unpack_trees()'
(currently the only way 'oneway_diff()' can be called, via 'diff_cache()')
will always traverse trees down to the individual removed files of a deleted
sparse directory. A subsequent patch will change this to better preserve a
sparse index in other uses of 'unpack_tree()', e.g. 'git reset --hard'.
However, making that change without this patch would result in (among other
issues) 'git status' printing only the name of a deleted sparse directory,
not its contents. To avoid introducing that bug, 'do_oneway_diff()' is
updated before modifying 'unpack_trees()'.

49ff3cb90f checkout: fix nested sparse directory diff in sparse index
Add the 'recursive' diff flag to the local changes reporting done by 'git
checkout' in 'show_local_changes()'. Without the flag enabled, unexpanded
sparse directories will not be recursed into to report the diff of each
file's contents, resulting in the reported local changes including
"modified" sparse directories.

The same issue was found and fixed for 'git status' in 2c521b0e49 (status:

3f7207e2ea mingw: handle a file owned by the Administrators group correctly
When an Administrator creates a file or directory, the created
file/directory is owned not by the Administrator SID, but by the
_Administrators Group_ SID. The reason is that users with administrator
privileges usually run in unprivileged ("non-elevated") mode, and their
user SID does not change when running in elevated mode.

This is is relevant e.g. when running a GitHub workflow on a build
agent, which runs in elevated mode: cloning a Git repository in a script
step will cause the worktree to be owned by the Administrators Group
SID, for example.

Let's handle this case as following: if the current user is an
administrator, Git should consider a worktree owned by the
Administrators Group as if it were owned by said user.

17d3883fe9 setup: prepare for more detailed "dubious ownership" messages
When verifying the ownership of the Git directory, we sometimes would
like to say a bit more about it, e.g. when using a platform-dependent
code path (think: Windows has the permission model that is so different
from Unix'), but only when it is a appropriate to actually say
something.

To allow for that, collect that information and hand it back to the
caller (whose responsibility it is to show it or not).

Note: We do not actually fill in any platform-dependent information yet,
this commit just adds the infrastructure to be able to do so.

99ddc24672 hook API: don't segfault on strbuf_addf() to NULL "out"
Fix a logic error in a082345372 (hook API: fix v2.36.0 regression:
hooks should be connected to a TTY, 2022-06-07). When it started using
the "ungroup" API added in fd3aaf53f7 (run-command: add an "ungroup"
option to run_process_parallel(), 2022-06-07) it should have made the
same sort of change that fd3aaf53f7 itself made in
"t/helper/test-run-command.c".

The correct way to emit this "Couldn't start" output with "ungroup"
would be:

	fprintf(stderr, _("Couldn't start hook '%s'\n"), hook_path);

But we should instead remove the emitting of this output. As the added
test shows we already emit output when we can't run the child. The
"cannot run" output here is emitted by run-command.c's
child_err_spew().

So the addition of the "Couldn't start hook" output here in
96e7225b31 (hook: add 'run' subcommand, 2021-12-22) was always
redundant. For the pre-commit hook we'll now emit exactly the same
output as we did before f443246b9f (commit: convert
{pre-commit,prepare-commit-msg} hook to hook.h, 2021-12-22) (and
likewise for others).

We could at this point add this to the pick_next_hook() callbacks in
hook.c:

	assert(!out);
	assert(!*pp_task_cb);

And this to notify_start_failure() and notify_hook_finished() (in the
latter case the parameter is called "pp_task_cp"):

	assert(!out);
	assert(!pp_task_cb);

But let's leave any such instrumentation for some eventual cleanup of
the "ungroup" API.

844739ba27 git docs: add a category for file formats, protocols and interfaces
Create a new "File formats, protocols and other developer interfaces"
section in the main "git help git" manual page and start moving the
documentation that now lives in "Documentation/technical/*.git" over
to it. This complements the newly added and adjacent "Repository,
command and file interfaces" section.

This makes the technical documentation more accessible and
discoverable. Before this we wouldn't install it by default, and had
no ability to build man page versions of them. The links to them from
our existing documentation link to the generated HTML version of these
docs.

So let's start moving those over, starting with just the
"bundle-format.txt" documentation added in 7378ec90e1 (doc: describe
Git bundle format, 2020-02-07). We'll now have a new
gitformat-bundle(5) man page. Subsequent commits will move more git
internal format documentation over.

Unfortunately the syntax of the current Documentation/technical/*.txt
is not the same (when it comes to section headings etc.) as our
Documentation/*.txt documentation, so change the relevant bits of
syntax as we're moving this over.

Create a new "Repository, command and file interfaces" section in the

The "Guides" section was added in f442f28a81 (git.txt: add list of

"gitfaq(7)" listed under "Guides".

But placing e.g. "gitignore(5)" in it is stretching the meaning of
what a "guide" is, ideally that section should list things similar to
"giteveryday(7)" and "gitcore-tutorial(7)".

An alternate name that was considered for this new section was "User
formats", for consistency with the nomenclature used for man section 5
in general. My man(1) lists it as "File formats and conventions,
e.g. /etc/passwd".

So calling this "git help --formats" or "git help --user-formats"
would make sense for e.g. gitignore(5), but would be stretching it
somewhat for githooks(5), and would seem really suspect for the likes
of gitcli(7).

Let's instead pick a name that's closer to the generic term "User
interface", which is really what this documentation discusses: General
user-interface documentation that doesn't obviously belong elsewhere.

dba1e5392f git help doc: use "<doc>" instead of "<guide>"
Replace the use of "<guide>" originally introduced (as "GUIDE") in
a133737b80 (doc: include --guide option description for "git help",
2013-04-02) with the more generic "<doc>". The "<doc>" placeholder is
more generic, and one we'll be able to use as we introduce new
documentation categories.

Let's also add "<doc>" to the "git help -h" output, when it was made
to use parse_option() in in 41eb33bd0c (help: use parseopt,
2008-02-24).

936b8eb6c8 help.c: remove common category behavior from drop_prefix() behavior
Change the behavior of the "git" prefix stripping for CAT_guide so
that we don't try to strip the "git-" prefix in that case. We should
be stripping either "git" or "git-" depending on the category. This
change makes it easier to add extra "category" conditions in
subsequent commits.

Before this we'd in principle strip a "git-" prefix from a "guide" in
command-list.txt, in practice we have no such entry there. As we don't
have any entry that looks like "git-foo" in command-list.txt this
changes nothing in practice, but it makes the intent of the code
clearer. In that hypothetical case we'd now strip it down to "-foo",
not "foo".

When this code was added in cfb22a02ab (help: use command-list.h for
common command list, 2018-05-10) the only entries in command-list.txt
that didn't begin with "git-" were "gitweb" and "gitk".

Then when the "guides" special-case was added in 1b81d8cb19 (help:
use command-list.txt for the source of guides, 2018-05-20) we had the
various "git" (not "git-") prefixed "guide" entries, which the
"CAT_guide" case handles.

2f8b3ea662 help.c: refactor drop_prefix() to use a "switch" statement"
Refactor the drop_prefix() function in in help.c to make it easier to
strip prefixes from categories that aren't "CAT_guide". There are no
functional changes here, by doing this we make a subsequent functional
change's diff smaller.

As before we first try to strip "git-" unconditionally, if that works
we'll return the stripped string. Then we'll strip "git" if the
command is in "CAT_guide".

This means that we'd in principle strip "git-foo" down to "foo" if
it's in CAT_guide. That doesn't make much sense, and we don't have
such an entry in command-list.txt, but let's preserve that behavior
for now.

While we're at it remove a stray newline that had been added after the
"return name;" statement.

a6a58f7801 tests: cache glibc version check
131b94a10a ("test-lib.sh: Use GLIBC_TUNABLES instead of MALLOC_CHECK_
on glibc >= 2.34", 2022-03-04) introduced a check for the version of
glibc that is in use. This check is performed as part of
setup_malloc_check() which is called at least once for each test. As
the test involves forking `getconf` and `expr` cache the result and
use that within setup_malloc_check() to avoid forking these extra
processes for each test.

cb54fc93e4 doc: clarify rerere-autoupdate
The "--[no-]rerere-autoupdate" option controls what happens _after_
the rerere mechanism kicks in to reuse recorded resolutions and does
not prevent from the rerere mechanism to trigger in the first place.

It is unclear in the current text if "--no-rerere-autoupdate" stops
the auto-resolution.  Rewrite the sentence to clarify.

0dbc715ae0 doc: consolidate --rerere-autoupdate description
The `--rerere-autoupdate` option is shared across 5 commands, and
are described the same way because it works exactly the same way in
these commands.

Create a separate file and include it from the help pages for these
commands, so that we can improve the description at one place to
improve all of them at once, and keep them in sync.
