75388bf5b4 branch: support more tracking modes when recursing
"git branch --recurse-submodules" does not propagate "--track=inherit"
or "--no-track" to submodules, which causes submodule branches to use
the wrong tracking mode [1]. To fix this, pass the correct options to
the "submodule--helper create-branch" child process and test for it.

While we are refactoring the same code, replace "--track" with the
synonymous, but more consistent-looking "--track=direct" option
(introduced at the same time as "--track=inherit", d3115660b4 (branch:
add flags and config to inherit tracking, 2021-12-20)).

[1] This bug is partially a timing issue: "branch --recurse-submodules"
 was introduced around the same time as "--track=inherit", and even
 though I rebased "branch --recurse-submodules" on top of that, I had
 neglected to support the new tracking mode. Omitting "--no-track"
 was just a plain old mistake, though.

b3c5f5cb04 submodule: move core cmd_update() logic to C
This patch completes the conversion past the flag parsing of
`submodule update` by introducing a helper subcommand called
`submodule--helper update`. The behaviour of `submodule update` should
remain the same after this patch.

Prior to this patch, `submodule update` was implemented by piping the
output of `update-clone` (which clones all missing submodules, then
prints relevant information for all submodules) into
`run-update-procedure` (which reads the information and updates the
submodule tree).

With `submodule--helper update`, we iterate over the submodules and
update the submodule tree in the same process. This reuses most of
existing code structure, except that `update_submodule()` now updates
the submodule tree (instead of printing submodule information to be
consumed by another process).

Recursing on a submodule is done by calling a subprocess that launches
`submodule--helper update`, with a modified `--recursive-prefix` and
`--prefix` parameter.

A later commit will combine the "update-clone" and

c9911c9358 submodule--helper: teach update_data more options
Refactor 'struct update_data' to hold the parsed args needed by "git
submodule--helper update" and refactor "update-clone" and
"run-update-procedure" (the functions that will be combined to form
"update") to use these options.

For "run-update-procedure", 'struct update_data' already holds its args,
so only arg parsing code needs to be updated.

For "update-clone", move its args from 'struct submodule_update_clone'
into 'struct update_data', and replace them with a pointer to 'struct
update_data'. Its other members hold the submodule iteration state of
"update-clone", so those are unchanged.

Incidentally, since we reformat the designated initializers of the
affected structs, also reformat MODULE_CLONE_DATA_INIT for consistency.

"git submodule update --filter" also requires the "--init" option. Teach
update-clone to do this usage check in C and remove the check from
git-submodule.sh.

In addition, change update-clone's usage string so that it teaches users
about "git submodule update" instead of "git submodule--helper
update-clone" (the string is copied from git-submodule.sh). This should
be more helpful to users since they don't invoke update-clone directly.

Move the logic of "git submodule--helper ensure-core-worktree" into
run-update-procedure, and since this makes the ensure-core-worktree
command obsolete, remove it.

As a result, the order of two operations in git-submodule.sh is
reversed: 'set the value of core.worktree' now happens after the call to
"git submodule--helper relative-path". This is safe - "relative-path"
does not depend on the value of core.worktree.

Teach "git submodule--helper update-clone" the --init flag and remove

When the `--init` flag is passed to the subcommand, we do not spawn a
new subprocess and call `submodule--helper init` on the submodule paths,
because the Git machinery is not able to pick up the configuration
changes introduced by that init call. So we instead run the
`init_submodule_cb()` callback over each submodule in the same process.

3ce52cba5b submodule--helper: allow setting superprefix for init_submodule()
We allow callers of the `init_submodule()` function to optionally
override the superprefix from the environment.

We need to enable this option because in our conversion of the update
command that will follow, the '--init' option will be handled through
this API. We will need to change the superprefix at that time to ensure
the display paths show correctly in the output messages.

a77c3fcb5e submodule--helper: get remote names from any repository
`get_default_remote()` retrieves the name of a remote by resolving the
refs from of the current repository's ref store.

Thus in order to use it for retrieving the remote name of a submodule,
we have to start a new subprocess which runs from the submodule
directory.

Let's instead introduce a function called `repo_get_default_remote()`
which takes any repository object and retrieves the remote accordingly.

`get_default_remote()` is then defined as a call to
`repo_get_default_remote()` with 'the_repository' passed to it.

Now that we have `repo_get_default_remote()`, we no longer have to start
a subprocess that called `submodule--helper get-default-remote` from
within the submodule directory.

So let's make a function called `get_default_remote_submodule()` which
takes a submodule path, and returns the default remote for that
submodule, all within the same process.

We can now use this function to save an unnecessary subprocess spawn in
`sync_submodule()`, and also in a subsequent patch, which will require
this functionality.

f05da2b48b clone, submodule: pass partial clone filters to submodules
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.

961b130d20 branch: add --recurse-submodules option for branch creation
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).

670703e9d6 Merge branch 'mp/absorb-submodule-git-dir-upon-deinit'
"git submodule deinit" for a submodule whose .git metadata
directory is embedded in its working tree refused to work, until
the submodule gets converted to use the "absorbed" form where the
metadata directory is stored in superproject, and a gitfile at the
top-level of the working tree of the submodule points at it.  The
command is taught to convert such submodules to the absorbed form
as needed.

0adc8ba6ae submodule: absorb git dir instead of dying on deinit
Currently, running 'git submodule deinit' on repos where the
submodule's '.git' is a directory, aborts with a message that is not
exactly user friendly.

Let's change this to instead warn the user that the .git/ directory
has been absorbed into the superproject.
The rest of the deinit function can operate as it already does with
new-style submodules.

In one test, we used to require "git submodule deinit" to fail even
with the "--force" option when the submodule's .git/ directory is not
absorbed. Adjust it to expect the operation to pass.

6b615dbece submodule: drop unused sm_name parameter from append_fetch_remotes()
Commit c21fb4676f (submodule--helper: fix incorrect newlines in an error
message, 2021-10-23) accidentally added a new, unused parameter while
changing the name and signature of show_fetch_remotes() to
append_fetch_remotes(). We can drop this to keep things simpler (and
satisfy -Wunused-parameter).

The error is likely because c21fb4676f is fixing a problem from
8c8195e9c3 (submodule--helper: introduce add-clone subcommand,
2021-07-10). An earlier iteration of that second commit introduced the
same unused parameter (though it was dropped before it finally made it
to 'next'), and the fix on top accidentally carried forward the extra
parameter.

c21fb4676f submodule--helper: fix incorrect newlines in an error message
A refactoring[1] done as part of the recent conversion of
'git submodule add' to builtin, changed the error message
shown when a Git directory already exists locally for a submodule
name. Before the refactoring, the error used to appear like so:

  --- START OF OUTPUT ---
  $ git submodule add ../sub/ subm
  A git directory for 'subm' is found locally with remote(s):
    origin        /me/git-repos-for-test/sub
  If you want to reuse this local git directory instead of cloning again from
    /me/git-repos-for-test/sub
  use the '--force' option. If the local git directory is not the correct repo
  or you are unsure what this means choose another name with the '--name' option.
  ---  END OF OUTPUT  ---

After the refactoring the error started appearing like so:

  --- START OF OUTPUT ---
  $ git submodule add ../sub/ subm
  A git directory for 'subm' is found locally with remote(s):  origin     /me/git-repos-for-test/sub
  fatal: If you want to reuse this local git directory instead of cloning again from
  /me/git-repos-for-test/sub
  use the '--force' option. If the local git directory is not the correct repo
  or if you are unsure what this means, choose another name with the '--name' option.

  ---  END OF OUTPUT  ---

As one could observe the remote information is printed along with the
first line rather than on its own line. Also, there's an additional
newline following output.

Make the error message consistent with the error message that used to be
printed before the refactoring.

This also moves the 'fatal:' prefix that appears in the middle of the
error message to the first line as it would more appropriate to have
it in the first line. The output after the change would look like:

  --- START OF OUTPUT ---
  $ git submodule add ../sub/ subm
  fatal: A git directory for 'subm' is found locally with remote(s):
    origin        /me/git-repos-for-test/sub
  If you want to reuse this local git directory instead of cloning again from
    /me/git-repos-for-test/sub
  use the '--force' option. If the local git directory is not the correct repo
  or you are unsure what this means choose another name with the '--name' option.
  ---  END OF OUTPUT  ---

f69a6e4f07 *.h: move some *_INIT to designated initializers
Move various *_INIT macros to use designated initializers. This helps
readability. I've only picked those leftover macros that were not
touched by another in-flight series of mine which changed others, but
also how initialization was done.

In the case of SUBMODULE_ALTERNATE_SETUP_INIT I've left an explicit
initialization of "error_mode", even though
SUBMODULE_ALTERNATE_ERROR_IGNORE itself is defined as "0". Let's not
peek under the hood and assume that enum fields we know the value of
will stay at "0".

The change to "TESTSUITE_INIT" in "t/helper/test-run-command.c" was
part of an earlier on-list version[1] of c90be786da (test-tool
run-command: fix flip-flop init pattern, 2021-09-11).

9865b6e6a4 *.[ch] *_INIT macros: use { 0 } for a "zero out" idiom
In C it isn't required to specify that all members of a struct are
zero'd out to 0, NULL or '\0', just providing a "{ 0 }" will
accomplish that.

Let's also change code that provided N zero'd fields to just
provide one, and change e.g. "{ NULL }" to "{ 0 }" for
consistency. I.e. even if the first member is a pointer let's use "0"
instead of "NULL". The point of using "0" consistently is to pick one,
and to not have the reader wonder why we're not using the same pattern
everywhere.

94b7f1563a Comment important codepaths regarding nuking untracked files/dirs
In the last few commits we focused on code in unpack-trees.c that
mistakenly removed untracked files or directories.  There may be more of
those, but in this commit we change our focus: callers of toplevel
commands that are expected to remove untracked files or directories.

As noted previously, we have toplevel commands that are expected to
delete untracked files such as 'read-tree --reset', 'reset --hard', and
'checkout --force'.  However, that does not mean that other highlevel
commands that happen to call these other commands thought about or
conveyed to users the possibility that untracked files could be removed.
Audit the code for such callsites, and add comments near existing
callsites to mention whether these are safe or not.

My auditing is somewhat incomplete, though; it skipped several cases:
  * git-rebase--preserve-merges.sh: is in the process of being
    deprecated/removed, so I won't leave a note that there are
    likely more bugs in that script.
  * contrib/git-new-workdir: why is the -f flag being used in a new
    empty directory??  It shouldn't hurt, but it seems useless.
  * git-p4.py: Don't see why -f is needed for a new dir (maybe it's
    not and is just superfluous), but I'm not at all familiar with
    the p4 stuff
  * git-archimport.perl: Don't care; arch is long since dead
  * git-cvs*.perl: Don't care; cvs is long since dead

Also, the reset --hard in builtin/worktree.c looks safe, due to only
running in an empty directory.
