Use the less verbose { 0 }-initialization syntax rather than memset()
in builtin/submodule--helper.c, this doesn't make a difference in
terms of behavior, but as we're about to modify adjacent code makes
this more consistent, and lets us avoid worrying about when the
memset() happens v.s. a "goto cleanup".

The usual style in the codebase is to separate declared variables with
a single newline, not two, let's adjust this code to conform to
that. This makes the eventual addition of various "int ret" variables
more consistent.
In doing this the comment added in 2964d6e5e1e (submodule: port
subcommand 'set-branch' from shell to C, 2020-06-02) might become
ambiguous to some, although it should be clear what it's referring to,
let's move it above the 'OPT_NOOP_NOARG('q', "quiet")' to make that
clearer.

As its name suggests the "resolve-relative-url-test" has never been
used outside of the test suite, see 63e95beb085 (submodule: port
resolve_relative_url from shell to C, 2016-04-15) for its original
addition.
Perhaps it would make sense to drop this code entirely, as we feel
that we've got enough indirect test coverage, but let's leave that
question to a possible follow-up change. For now let's keep the test
coverage this gives us.

Move the "check-name" helper to a test-tool, since
a6226fd772b (submodule--helper: convert the bulk of cmd_add() to C,
2021-08-10) it has only been used by this test, not git-submodule.sh.
As noted with its introduction in 0383bbb9015 (submodule-config:
verify submodule names as paths, 2018-04-30) the intent of
t7450-bad-git-dotfiles.sh has always been to unit test the

Create a new "test-tool submodule" and move the "is-active" subcommand
over to it. It was added in 5c2bd8b77ae (submodule--helper: add
is-active subcommand, 2017-03-16), since
a452128a36c (submodule--helper: introduce add-config subcommand,
2021-08-06) it hasn't been used by git-submodule.sh.
Since we're creating a command dispatch similar to test-tool.c itself
let's split out the "struct test_cmd" into a new test-tool-utils.h,
which both this new code and test-tool.c itself can use.

used by git-submodule.sh since 2964d6e5e1e (submodule: port subcommand

There was a test added in 2b56bb7a87a (submodule helper list: respect

thing to do here is to delete that test as well.

Add a missing test for ""add <repository> <path>" where "<path>" is an
absolute path. This tests code added in [1] and later turned into an
"else" branch in clone_submodule() in [2] that's never been tested.
This needs to be skipped on WINDOWS because all of $PWD, $(pwd) and
the "$(pwd -P)" we get via "$submodurl" would fail in CI with e.g.:
fatal: could not create directory 'D:/a/git/git/t/trash
directory.t7400-submodule-basic/.git/modules/D:/a/git/git/t/trash
directory.t7400-submodule-basic/add-abs'
I.e. we can't handle these sorts of paths in this context on that
platform.
I'm not sure where we run into the edges of "$PWD" behavior on
Windows (see [1] for a previous loose end on the topic), but for the
purposes of this test it's sufficient that we test this on other
platforms.

Test what exit code and output we emit on "git submodule -h", how we
handle "--" when no subcommand is specified, and how the top-level
"--recursive" option is handled.
For "-h" this doesn't make sense, but let's test for it so that any
subsequent eventual behavior change will become clear.
For "--" this follows up on 68cabbfda36 (submodule: document default
behavior, 2019-02-15) and tests that "status" doesn't support
the "--" delimiter. There's no intrinsically good reason not to
support that. We behave this way due to edge cases in
git-submodule.sh's implementation, but as with "-h" let's assert our
current long-standing behavior for now.
For "--recursive" the exclusion of it from the top-level appears to
have been an omission in 15fc56a8536 (git submodule foreach: Add
--recursive to recurse into nested submodules, 2009-08-19), there
doesn't seem to be a reason not to support it alongside "--quiet" and
"--cached", but let's likewise assert our existing behavior for now.
I.e. as long as "status" is optional it would make sense to support
all of its options when it's omitted, but we only do that with
"--quiet" and "--cached", and curiously omit "--recursive".

Although parse_options() can handle unknown --options just fine, none
of 'git multi-pack-index's subcommands rely on it, but do it on their
own: they invoke parse_options() with the PARSE_OPT_KEEP_UNKNOWN flag,
then check whether there are any unparsed arguments left, and print
usage and quit if necessary.
Drop that PARSE_OPT_KEEP_UNKNOWN flag to let parse_options() handle
unknown options instead, which has the additional benefit that it
prints not only the usage but an "error: unknown option `foo'" message
as well.
Do leave the unparsed arguments check to catch any unexpected
non-option arguments, though, e.g. 'git multi-pack-index write foo'.

For SHA-256, we currently have support for OpenSSL and libgcrypt because
these two libraries contain optimized implementations that can take
advantage of native processor instructions. However, OpenSSL is not
suitable for linking against for Linux distros due to licensing
incompatibilities with the GPLv2, and libgcrypt has been less favored by
cryptographers due to some security-related implementation issues,
which, while not affecting our use of hash algorithms, has affected its
reputation.
Let's add another option that's compatible with the GPLv2, which is
Nettle. This is an option which is generally better than libgcrypt
because on many distros GnuTLS (which uses Nettle) is used for HTTPS and
therefore as a practical matter it will be available on most systems.
As a result, prefer it over libgcrypt and our built-in implementation.
Nettle also has recently gained support for Intel's SHA-NI instructions,
which compare very favorably to other implementations, as well as
assembly implementations for when SHA-NI is not available.
A git gc on git.git sees a 12% performance improvement with Nettle over
our block SHA-256 implementation due to general assembly improvements.
With SHA-NI, the performance of raw SHA-256 on a 2 GiB file goes from
7.296 seconds with block SHA-256 to 1.523 seconds with Nettle.

The variables 'source', 'destination', and 'submodule_gitfile' are
all of type "const char **", and an element of such an array is of
"type const char *", but these memmove() calls were written as if
these variables are of type "char **".
Once these memmove() calls are fixed to use the correct type to
compute the number of bytes to be moved, e.g.
- memmove(source + i, source + i + 1, n * sizeof(char *));
+ memmove(source + i, source + i + 1, n * sizeof(const char *));
existing contrib/coccinelle/array.cocci rules can recognize them as
candidates for turning into MOVE_ARRAY().
While at it, use CALLOC_ARRAY() instead of xcalloc() to allocate the
modes[] array that is involved in the change.

'vim' has two configuration options ('splitbelow' and 'splitright') that
change the way the 'split' command behaves. When they are set, the
commands that the layout engine generates no longer work as expected.
In order to fix this we can append special keyword 'leftabove' to each
'split' and 'vertical split' subcommand found inside the command string
generated by the layout engine.
This works because whatever comes after 'leftabove' will temporally
ignore settings 'splitbelow' and 'splitright'.

Generalize the newly added "unused.cocci" rule to find more than just
"struct strbuf", let's have it find the same unused patterns for
"struct string_list", as well as other code that uses
similar-looking *_{release,clear,free}() and {release,clear,free}_*()
functions.
We're intentionally loose in accepting e.g. a "strbuf_init(&sb)"
followed by a "string_list_clear(&sb, 0)". It's assumed that the
compiler will catch any such invalid code, i.e. that our
constructors/destructors don't take a "void *".
See [1] for example of code that would be covered by the
"get_worktrees()" part of this rule. We'd still need work that the
series is based on (we were passing "worktrees" to a function), but
could now do the change in [1] automatically.

Add a coccinelle rule to remove "struct strbuf" initialization
followed by calling "strbuf_release()" function, without any uses of

See the tests in contrib/coccinelle/tests/unused.{c,res} for what it's

The inclusion of "contrib/scalar/scalar.c" is because "spatch" was
manually run on it (we don't usually run spatch on contrib).
Per the "buggy code" comment we also match a strbuf_init() before the
xmalloc(), but we're not seeking to be so strict as to make checks
that the compiler will catch for us redundant. Saying we'll match
either "init" or "xmalloc" lines makes the rule simpler.

Have the newly introduced "coccicheck-test" target run implicitly when
"coccicheck" itself is run. As with e.g. the "check-chainlint"
target (see [1]) it makes sense to run this unconditionally before we
run other "spatch" rules as a basic sanity check. See

Add a "coccicheck-test" target to test our *.cocci rules, and as a
demonstration add tests for the rules added in 39ea59a2570 (remove
unnecessary NULL check before free(3), 2016-10-08) and
1b83d1251ed (coccinelle: add a rule to make "expression" code use
FREE_AND_NULL(), 2017-06-15).
I considered making use of the "spatch --test" option, and the choice
of a "tests" over a "t" directory is to make these tests compatible
with such a future change.
Unfortunately "spatch --test" doesn't return meaningful exit codes,
AFAICT you need to "grep" its output to see if the *.res is what you
expect. There's "--test-okfailed", but I didn't find a way to sensibly
integrate those (it relies on some in-between status files, but
doesn't help with the status codes).
Instead let's use a "--sp-file" pattern similar to the main
"coccicheck" rule, with the difference that we use and compare the
two *.res files with cmp(1).
The --very-quiet and --no-show-diff options ensure that we don't need
to pipe stdout and stderr somewhere. Unlike the "%.cocci.patch" rule
we're not using the diff.
The "cmp || git diff" is optimistically giving us better output on
failure, but even if we only have POSIX cmp and no system git
installed we'll still fail with the "cmp", just with an error message
that isn't as friendly. The "2>/dev/null" is in case we don't have a
"git" installed.

The "--patch ." part of SPATCH_FLAGS added in f57d11728d1 (coccinelle:
put sane filenames into output patches, 2018-07-23) should have been
added unconditionally to the "spatch" invocation instead, using it
isn't optional.
Let's also move the other mandatory flag to come after
$(SPATCH_FLAGS), to ensure that our "--sp-file" overrides any provided
in the environment, both --sp-file <arg> and --patch <arg> are
last-option-wins as far as spatch(1) option parsing is concerned.
The environment variable override was initially added in
a9a884aea57 (coccicheck: use --all-includes by default,
2016-09-30). In practice there's probably nobody that's using
SPATCH_FLAGS to try to intentionally break our invocations, but since
we're changing this let's make it clear what (if anything) we expect
to be overridden by user-supplied flags.

There is code in both merge-recursive and merge-ort for avoiding doubly
transitive renames (i.e. one side renames directory A/ -> B/, and the
other side renames directory B/ -> C/), because this combination would
otherwise make a mess for new files added to A/ on the first side and
wondering which directory they end up in -- especially if there were
even more renames such as the first side renaming C/ -> D/. In such
cases, it just turns "off" directory rename detection for the higher
order transitive cases.
The testcases added in t6423 a couple commits ago are slightly different
but similar in principle. They involve a similar case of paired
renaming but instead of A/ -> B/ and B/ -> C/, the second side renames
a leading directory of B/ to C/. And both sides add a new file
somewhere under the directory that the other side will rename. While
the new files added start within different directories and thus could
logically end up within different directories, it is weird for a file
on one side to end up where the other one started and not move along
with it. So, let's just turn off directory rename detection in this
case as well.
Another way to look at this is that if the source name involved in a
directory rename on one side is the target name of a directory rename
operation for a file from the other side, then we avoid the doubly
transitive rename. (More concretely, if a directory rename on side D
wants to rename a file on side E from OLD_NAME -> NEW_NAME, and side D
already had a file named NEW_NAME, and a directory rename on side E
wants to rename side D's NEW_NAME -> NEWER_NAME, then we turn off the
directory rename detection for NEW_NAME to prevent the
NEW_NAME -> NEWER_NAME rename, and instead end up with an add/add
conflict on NEW_NAME.)

This is an attempt at minimalizing a testcase reported by Glen Choo
with tensorflow where merge-ort would report an assertion failure:
Assertion failed: (ci->filemask == 2 || ci->filemask == 4), function apply_directory_rename_modifications, file merge-ort.c, line 2410
reversing the direction of the merge provides a different error:
error: cache entry has null sha1: ...
fatal: unable to write .git/index
so we add testcases for both. With these new testcases, the
recursive strategy differs in that it returns the latter error for
both merge directions.
These testcases are somehow a little different than Glen's original
tensorflow testcase in that these ones trigger a bug with the recursive
algorithm whereas his testcase didn't. I figure that means these
testcases somehow manage to be more comprehensive.

Update the behavior so that:
1. Moving from out-of-cone to in-cone removes the SKIP_WORKTREE bit from

issue" in this series.
This change tests the following:

would be a sparse directory in a sparse index).
2. mv <source> as a directory which is deeper than the boundary (so
the sparse index would expand in the cache_name_pos() method).

can be updated to use the 'ensure_not_expanded' helper in t1092.

In 1c41d2805e4 (unpack_trees_options: free messages when done,
2018-05-21) we started calling clear_unpack_trees_porcelain() on this
codepath, but missed this error path.
We could call clear_unpack_trees_porcelain() just before we error()
and return when unmerged_cache() fails, but the more correct fix is to
not have the unmerged_cache() check happen in the middle of our
"topts" setup.
Before 23cbf11b5c0 (merge-recursive: porcelain messages for checkout,
2010-08-11) we would not malloc() to setup our "topts", which is when
this started to leak on the error path.
Before that this code wasn't conflating the setup of "topts" and the
unmerged_cache() call in any meaningful way. The initial version in
782c2d65c24 (Build in checkout, 2008-02-07) just does a "memset" of
it, and initializes a single struct member.
Then in 8ccba008ee3 (unpack-trees: allow Porcelain to give different
error messages, 2008-05-17) we added the initialization of the error
message, which as noted above finally started leaking in 23cbf11b5c0.

so something like

Unlike the other subcommands, "git submodule--helper update" uses the
"--recursive-prefix" flag instead of "--super-prefix". The two flags are
otherwise identical (they only serve to compute the 'display path' of a
submodule), except that there is a dedicated helper function to get the
value of "--super-prefix".
This inconsistency exists because "git submodule update" used to pass
"--recursive-prefix" between shell and C (introduced in [1]) before
"--super-prefix" was introduced (in [2]), and for simplicity, we kept
this name when "git submodule--helper update" was created.
Remove "--recursive-prefix" and its associated code from "git
submodule--helper update", replacing it with "--super-prefix".
To use "--super-prefix", module_update is marked with
SUPPORT_SUPER_PREFIX. Note that module_clone must also be marked with
SUPPORT_SUPER_PREFIX, otherwise the "git submodule--helper clone"
subprocess will fail check because "--super-prefix" is propagated via
the environment.

Remove the SUPPORT_SUPER_PREFIX flag from "add", "init" and
"summary". For the "add" command it hasn't been used since [1],
likewise for "init" and "summary" since [2] and [3], respectively.
As implemented in 74866d75793 (git: make super-prefix option,
2016-10-07) the SUPPORT_SUPER_PREFIX flag in git.c applies for the
entire command, but as implemented in 89c86265576 (submodule helper:

Replace a chunk of code in update_submodule() with an equivalent
do_get_submodule_displaypath() invocation. This is already tested by
t/t7406-submodule-update.sh:'submodule update --init --recursive from
subdirectory', so no tests are added.
The two are equivalent because:
- Exactly one of recursive_prefix|prefix is non-NULL at a time; prefix
is set at the superproject level, and recursive_prefix is set when
recursing into submodules. There is also a BUG() statement in
get_submodule_displaypath() that asserts that both cannot be non-NULL.
- In get_submodule_displaypath(), get_super_prefix() always returns NULL
because "--super-prefix" is never passed. Thus calling it is
equivalent to calling do_get_submodule_displaypath() with super_prefix
= NULL.
Therefore:
- When recursive_prefix is non-NULL, prefix is NULL, and thus
get_submodule_displaypath() just returns prefixed_path. This is
identical to calling do_get_submodule_displaypath() with super_prefix
= recursive_prefix because the return value is still the concatenation
of recursive_prefix + update_data->sm_path.
- When prefix is non-NULL, prefixed_path = update_data->sm_path. Thus
calling get_submodule_displaypath() with prefixed_path is equivalent
to calling do_get_submodule_displaypath() with update_data->sm_path

update_submodule() uses duplicated code to compute
update_data->displaypath and next.recursive_prefix. The latter is just
the former with "/" appended to it, and since update_data->displaypath
not changed outside of this statement, we can just reuse the already
computed result.
We can go one step further and remove the reference to
next.recursive_prefix altogether. Since it is only used in
update_data_to_args() (to compute the "--recursive-prefix" flag for the
recursive update child process) we can just use the already computed
.displaypath value of there.
Delete the duplicated code, and remove the unnecessary reference to
next.recursive_prefix. As a bonus, this fixes a memory leak where
prefixed_path was never freed (this leak was first reported in [1]).

There are two locations in prepare_to_clone_next_submodule() that
manually calculate the submodule display path, but should just use
do_get_submodule_displaypath() for consistency.
Do this replacement and reorder the code slightly to avoid computing
the display path twice.
Until the preceding commit this code had never been tested, with our
newly added tests we can see that both these sites have been computing
the display path incorrectly ever since they were introduced in
48308681b0 (git submodule update: have a dedicated helper for cloning,
2016-02-29) [1]:
- The first hunk puts a "/" between recursive_prefix and ce->name, but
recursive_prefix already ends with "/".
- The second hunk calls relative_path() on recursive_prefix and
ce->name, but relative_path() only makes sense when both paths share
the same base directory. This is never the case here:
- recursive_prefix is the path from the topmost superproject to the
current submodule
- ce->name is the path from the root of the current submodule to its
submodule.
so, e.g. recursive_prefix="super" and ce->name="submodule" produces
displayname="../super" instead of "super/submodule".
[1] I verified this by applying the tests to 48308681b0.

The "test_when_finished" cleanup phase added in 4179b4897f2 (config:
allow overriding of global and system configuration, 2021-04-19) has
never worked as intended, firstly the ".config/git" is a directory, so
we'd need the "-r" flag, but more importantly the $HOME variable
wasn't properly quoted.
We'd thus end up trying to remove the "trash" part of "trash
directory", which wouldn't fail with "-f", since "rm -f" won't fail on
non-existing files.
It's possible that this would have caused an actual failure if someone
had a $HOME with a space character in it, such that our "rm -f" would
fail to remove an existing directory, but in practice that probably
never happened.
Let's fix both the quoting issue, and the other issue cleanup issue in
4179b4897f2, which is that we were attempting to clean up
~/.config/git, but weren't cleaing up ~/.gitconfig.

While inspecting the 'git rebase' documentation, I noticed that it is
inconsistent with how it uses back-ticks (or other punctuation) for
identifying Git commands, command-line arguments, or values for those
arguments.
Sometimes, an argument (like '--interactive') would appear without any
punctuation, causing the argument to not have any special formatting.
Other times, arguments or 'git rebase' itself would have single-quotes
giving a bold look (in the HTML documentation at least).
By consistently using back-ticks, these types of strings appear in a
monospace font with special highlighting to appear more clearly as text
that exists in a command-line invocation of a Git command.
This rather-large diff is the result of scanning git-rebase.txt and
adding back-ticks as appropriate. Some are adding back-ticks where there
was no punctuation. Others are replacing single quotes.
There are also a few minor cleanups in the process, including those
found by reviewers.

The size and padding of `struct object_entry` is an important factor in
determining the memory usage of `pack-objects`. For this reason,
3b13a5f263 (pack-objects: reorder members to shrink struct object_entry,
2018-04-14) added a comment containing some information from pahole
indicating the size and padding of that struct.
Unfortunately, this comment hasn't been updated since 9ac3f0e5b3
(pack-objects: fix performance issues on packing large deltas,
2018-07-22), despite the size of this struct changing many times since
that commit.
To see just how often the size of object_entry changes, I skimmed the
first-parent history with this script:
for sha in $(git rev-list --first-parent --reverse 9ac3f0e..)
do
echo -n "$sha "
git checkout -q $sha
make -s pack-objects.o 2>/dev/null
pahole -C object_entry pack-objects.o | sed -n \
-e 's/\/\* size: \([0-9]*\).*/size \1/p' \
-e 's/\/\*.*padding: \([0-9]*\).*/padding \1/p' | xargs
done | uniq -f1
In between each merge, the size of object_entry changes too often to
record every instance here. But the important merges (along with their
corresponding sizes and bit paddings) in chronological order are:
ad635e82d6 (Merge branch 'nd/pack-objects-pack-struct', 2018-05-23) size 80 padding 4
29d9e3e2c4 (Merge branch 'nd/pack-deltify-regression-fix', 2018-08-22) size 80 padding 9
3ebdef2e1b (Merge branch 'jk/pack-delta-reuse-with-bitmap', 2018-09-17) size 80 padding 8
33e4ae9c50 (Merge branch 'bc/sha-256', 2019-01-29) size 96 padding 8
(indicating that the current size of the struct is 96 bytes, with 8
padding bits).
Even though this comment was written in a good spirit, it is updated
infrequently enough that it serves to confuse rather than to encourage
contributors to update the appropriate values when the modify the
definition of object_entry.
For that reason, eliminate the confusion by removing the comment
altogether.

From looking at the {Free,Net,Dragonfly}BSD packages for git[1]
they've been monkeypatching "gitweb" out of the Makefile, let's be
nicer and provide a NO_GITWEB=Y for their use.
For the "all" target this allows for optionally restoring what's been
the status quo before the preceding commit, but now we'll also behave
correctly on the subsequent "make install".
As before our installation of gitweb can be suppressed with
NO_PERL. For backwards compatibility the NO_PERL=Y flag by itself
still doesn't change whether or not we build gitweb, unlike the new
NO_GITWEB=Y flag.

Our Makefile's default target used to build 'gitweb', though
indirectly: the 'all' target depended on 'git-instaweb', which in turn
depended on 'gitweb'. Then e25c7cc146 (Makefile: drop dependency
between git-instaweb and gitweb, 2015-05-29) removed the latter
dependency, and for good reasons (quoting its commit message):
"1. git-instaweb has no build-time dependency on gitweb; it
is a run-time dependency
2. gitweb is a directory that we want to recursively make
in. As a result, its recipe is marked .PHONY, which
causes "make" to rebuild git-instaweb every time it is
run."
Since then a simple 'make' doesn't build 'gitweb'.
Luckily, installing 'gitweb' is not broken: although 'make install'
doesn't depend on the 'gitweb' target, it has a dependency on the
'install-gitweb' target, which does generate all the necessary files
for 'gitweb' and installs them. However, if someone runs 'make &&
sudo make install', then those files in the 'gitweb' directory will be
generated and owned by root, which is not nice.
List 'gitweb' as a direct dependency of the default target, so a plain
'make' will build it.

Follow-up on the preceding commit which taught "git submodule--helper

the command invokes itself.
Unlike the preceding change this isn't strictly necessary to

inconsistency in the command-line interface. We shouldn't need to
carry special synonyms for existing options in "git submodule--helper"
when that command can use the primary documented names instead.
But, as seen in the post-image this makes the control flow within

the "update_default" member of "struct update_data" when parsing the
options in "module_update()".

Change the user-facing "git submodule--helper" commands so that
they'll report their name as being "git submodule". To a user these
commands are internal implementation details, and it doesn't make
sense to emit usage about an internal helper when "git submodule" is
invoked with invalid options.
Before this we'd emit e.g.:
$ git submodule absorbgitdirs --blah
error: unknown option `blah'
usage: git submodule--helper absorbgitdirs [<options>] [<path>...]
[...]
And:
$ git submodule set-url -- --
usage: git submodule--helper set-url [--quiet] <path> <newurl>
[...]
Now we'll start with "usage: git submodule [...]" in both of those
cases. This change does not alter the "list", "name", "clone",
"config" and "create-branch" commands, those are internal-only (as an
aside; their usage info should probably invoke BUG(...)). This only
changes the user-facing commands.
The "status", "deinit" and "update" commands are not included in this
change, because their usage information already used "submodule"
rather than "submodule--helper".
I don't think it's currently possible to emit some of this usage
information in practice, as git-submodule.sh will catch unknown
options, and e.g. it doesn't seem to be possible to get "add" to emit
its usage information from "submodule--helper".
Though that change may be superfluous now, it's also harmless, and
will allow us to eventually dispatch further into "git
submodule--helper" from git-submodule.sh, while emitting the correct
usage output.

In e84c3cf3dc3 (git-submodule.sh: accept verbose flag in cmd_update to
be non-quiet, 2018-08-14) the "git submodule update" sub-command was
made to understand "-v", but the option was never documented.
The only in-tree user has been this test added in

it on "-v", and thus we'd end up passing "--quiet" to "git
submodule--helper" on "-v", since the "--quiet" option was passed
using the ${parameter:+word} construct.
Furthermore, even if someone had used the "-v" option they'd only be
getting the default output. Our default in both git-submodule.sh and
"git submodule--helper" has been to be "verbose", so the only way this
option could have matter is if it were used as e.g.:

I.e. to undo the effect of a previous "--quiet" on the command-line.

In 5c08dbbdf1a (git-submodule: fix subcommand parser, 2008-01-15) the
"--branch" option was supported as an option to "git submodule"
itself, i.e. "git submodule --branch" as a side-effect of its
implementation.
Then in b57e8119e6e (submodule: teach set-branch subcommand,
2019-02-08) when the "set-branch" subcommand was added the assertion
that we shouldn't have "--branch" anywhere except as an argument to
"add" and "set-branch" was copy/pasted from the adjacent check for
"--cache" added (or rather modified) in 496eeeb19b9 (git-submodule.sh:
avoid "test <cond> -a/-o <cond>", 2014-06-10).
But there's been a logic error in that check, which at a glance looked
like it should be supporting:
git submodule --branch <branch> (add | set-branch) [<options>]
But due to "||" in the condition (as opposed to "&&" for "--cache") if
we have "--branch" here already we'll emit usage, even for "add" and
"set-branch".
So in addition to never having documented this form, it hasn't worked
since b57e8119e6e was released with v2.22.0.
So it's safe to remove this code. I.e. we don't want to support the
form noted above, but only:
git submodule (add | set-branch) --branch <branch> [<options>]

Remove the assignment of "$1" to the "$cached" variable. As seen in
the initial implementation in 70c7ac22de6 (Add git-submodule command,
2007-05-26) we only need to keep track of if we've seen the --cached
option, not save the "--cached" string for later use.
In 28f9af5d25e (git-submodule summary: code framework, 2008-03-11)
"$1" was assigned to it, but since there was no reason to do so let's
stop doing it. This trivial change will make it easier to reason about
an eventual change that'll remove the cmd_summary() function in favor
of dispatching to "git submodule--helper summary" directly.

Remove the $prefix variable which isn't used anymore, and hasn't been
since b3c5f5cb048 (submodule: move core cmd_update() logic to C,
2022-03-15).
Before that we'd use it to invoke "git submodule--helper" with the
"--recursive-prefix" option, but since b3c5f5cb048 that "git
submodule--helper" option is only used when it invokes itself.
So the "--recursive-prefix" option is still in use, but at this point
only when the helper invokes itself during submodule recursion. See
the "--recursive-prefix" option added in
c51f8f94e5b (submodule--helper: run update procedures from C,
2021-08-24).

The contrib/vscode/init.sh script initializes the .vscode directory with
some helpful metadata so VS Code handles Git code better.
One big issue that VS Code has is detecting the tab width based on file
type. ".txt" files were not covered by this script before, so add them
with the appropriate tab widths. This prevents inserting spaces instead
of tabs and keeps the tab width to eight instead of four or two.
While we are here, remove the "editor.wordWrap" settings. The editor's
word wrap is only cosmetic: it does not actually insert newlines when
your typing goes over the column limit. This can make it appear like you
have properly wrapped code, but it is incorrect. Further, existing code
that is over the column limit is wrapped even if your editor window is
wider than the limit. This can make reading such code more difficult.
Without these lines, VS Code renders the lines accurately, without
"ghost" newlines.

8959555cee7 (setup_git_directory(): add an owner check for the top-level
directory, 2022-03-02), adds a function to check for ownership of
repositories using a directory that is representative of it, and ways to
add exempt a specific repository from said check if needed, but that
check didn't account for owership of the gitdir, or (when used) the
gitfile that points to that gitdir.
An attacker could create a git repository in a directory that they can
write into but that is owned by the victim to work around the fix that
was introduced with CVE-2022-24765 to potentially run code as the
victim.
An example that could result in privilege escalation to root in *NIX would
be to set a repository in a shared tmp directory by doing (for example):
$ git -C /tmp init
To avoid that, extend the ensure_valid_ownership function to be able to
check for all three paths.
This will have the side effect of tripling the number of stat() calls
when a repository is detected, but the effect is expected to be likely
minimal, as it is done only once during the directory walk in which Git
looks for a repository.
Additionally make sure to resolve the gitfile (if one was used) to find
the relevant gitdir for checking.
While at it change the message printed on failure so it is clear we are
referring to the repository by its worktree (or gitdir if it is bare) and
not to a specific directory.

In asciidoc's HTML output of the "gitrevisions" and "git-rev-parse"
documentation, the header:
The ... (three-dot) Symmetric Difference Notation
is rendered using "&8230;", a horizontal ellipsis. This is visually
ugly, but also hard to search for or cut-and-paste. We really mean three
ascii dots (0x2e) here, so let's make sure it renders as such.
The simplest way to do that is just escaping the leading dot, as the
instances in the rest of the section do. Arguably this should all be
converted to use backticks, which would let us drop the quoting here and
elsewhere (e.g., {carat}). But that does change the rendering slightly.
So let's fix the bug first, and we can decide on migrating the whole
section separately.
Note that this produces an empty doc-diff of the manpages. Curiously,
asciidoc produces the same ellipsis entity in the XML file, but docbook
then converts it back into three literal dots for the roff output! So
the roff manpages have been correct all along (which may be a reason
nobody noticed this until now).

It is all fine and dandy for a regular Git command that is intended to
be run interactively to produce a bunch of messages upon an error.
However, in `merge-ort`'s case, we want to call the command e.g. in
server-side software, where the actual error messages are not quite as
interesting as machine-readable, immutable terms that describe the exact
nature of any given conflict.
With this patch, the `merge-ort` machinery records the exact type (as
specified via an `enum` value) as well as the involved path(s) together
with the conflict's message.

To prepare for using the `merge-ort` machinery in server operations, we
cannot simply produce a free-form string that combines a variable-length
list of messages.
Instead, we need to list them one by one. The natural fit for this is a
`string_list`.
We will subsequently add even more information in the `util` attribute
of the string list items.

There was one case in merge-ort that would call path_msg() multiple
times for the same logical conflict, and it was in order to give advice
about how to resolve a conflict. This advice does not make as much
sense with remerge-diff, or with merge-tree being invoked by a GitHub
GUI for resolution of messages, and is making it hard to provide

When running `git merge-tree --write-tree`, we previously would only
return an exit status reflecting the cleanness of a merge, and print out
the toplevel tree of the resulting merge. Merges also have
informational messages, such as:
* "Auto-merging <PATH>"
* "CONFLICT (content): ..."
* "CONFLICT (file/directory)"
* etc.
In fact, when non-content conflicts occur (such as file/directory,
modify/delete, add/add with differing modes, rename/rename (1to2),
etc.), these informational messages may be the only notification the
user gets since these conflicts are not representable in the contents
of the file.
Add a --[no-]messages option so that callers can request these messages
be included at the end of the output. Include such messages by default
when there are conflicts, and omit them by default when the merge is
clean.

This adds the ability to perform real merges rather than just trivial
merges (meaning handling three way content merges, recursive ancestor
consolidation, renames, proper directory/file conflict handling, and so
forth). However, unlike `git merge`, the working tree and index are
left alone and no branch is updated.
The only output is:
- the toplevel resulting tree printed on stdout
- exit status of 0 (clean), 1 (conflicts present), anything else
(merge could not be performed; unknown if clean or conflicted)
This output is meant to be used by some higher level script, perhaps in
a sequence of steps like this:
NEWTREE=$(git merge-tree --write-tree $BRANCH1 $BRANCH2)
test $? -eq 0 || die "There were conflicts..."
NEWCOMMIT=$(git commit-tree $NEWTREE -p $BRANCH1 -p $BRANCH2)
git update-ref $BRANCH1 $NEWCOMMIT
Note that higher level scripts may also want to access the
conflict/warning messages normally output during a merge, or have quick
access to a list of files with conflicts. That is not available in this
preliminary implementation, but subsequent commits will add that
ability (meaning that NEWTREE would be a lot more than a tree in the
case of conflicts).
This also marks the traditional trivial merge of merge-tree as
deprecated. The trivial merge not only had limited applicability, the
output format was also difficult to work with (and its format
undocumented), and will generally be less performant than real merges.

Let merge-tree accept a `--write-tree` parameter for choosing real
merges instead of trivial merges, and accept an optional
`--trivial-merge` option to get the traditional behavior. Note that
these accept different numbers of arguments, though, so these names
need not actually be used.
Note that real merges differ from trivial merges in that they handle:
- three way content merges
- recursive ancestor consolidation
- renames
- proper directory/file conflict handling
- etc.
Basically all the stuff you'd expect from `git merge`, just without
updating the index and working tree. The initial shell added here does
nothing more than die with "real merges are not yet implemented", but
that will be fixed in subsequent commits.
