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).

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

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.

We currently store each submodule gitdir in ".git/modules/<name>", but

Extract the determination of the location of a submodule's gitdir into
its own function submodule_name_to_gitdir(). For now, the problem
remains unsolved, but this puts us in a better position for finding a
solution.
This was motivated, at $DAYJOB, by a part of Android's repo hierarchy

In get_submodule_repo_for(), there is a fallback code path for the case
in which a submodule has an unabsorbed gitdir. (See the documentation
for "git submodule absorbgitdirs" for more information about absorbed
and unabsorbed gitdirs.) However, this code path is unnecessary, because
such submodules are already handled: when the fetch_task is created in
fetch_task_create(), it will create its own struct submodule with a path
and name, and repo_submodule_init() can handle such a struct.
This fallback was introduced in 26f80ccfc1 ("submodule: migrate
get_next_submodule to use repository structs", 2018-12-05). It was
unnecessary even then, but perhaps it escaped notice because its parent
commit d5498e0871 ("repository: repo_submodule_init to take a submodule
struct", 2018-12-05) was the one that taught repo_submodule_init() to
handle such created structs. Before, it took a path and always checked
.gitmodules, so it truly would have failed if there were no entry in
.gitmodules.
(Note to reviewers: in 26f80ccfc1, the "own struct submodule" I
mentioned is in get_next_submodule(), not fetch_task_create().)

Teach Git to add submodule ODBs as alternates to the object store of
the_repository only upon the first access of an object not in
the_repository, and not when add_submodule_odb() is called.
This provides a means of gradually migrating from accessing a
submodule's object through alternates to accessing a submodule's object
by explicitly passing its repository object. Any Git command can declare
that it might access submodule objects by calling add_submodule_odb()
(as they do now), but the submodule ODBs themselves will not be added
until needed, so individual commands and/or combinations of arguments
can be migrated one by one.
[The advantage of explicit repository-object passing is code clarity (it
is clear which repository an object read is from), performance (there is
no need to linearly search through all submodule ODBs whenever an object
is accessed from any repository, whether superproject or submodule), and
the possibility of future features like partial clone submodules (which
right now is not possible because if an object is missing, we do not
know which repository to lazy-fetch into).]
This commit also introduces an environment variable that a test may set
to make the actual registration of alternates fatal, in order to
demonstrate that its codepaths do not need this registration.

If you have ever initialized a submodule, open_submodule will open it.
If you then delete the submodule's worktree directory (but don't
remove it from .gitmodules), git diff --submodule=diff would error out
as it attempted to chdir into the now-deleted working tree directory.
This only matters if the submodules git dir is absorbed. If not, then
we no longer have anywhere to run the diff. But that case does not
trigger this error, because in that case, open_submodule fails, so we
don't resolve a left commit, so we exit early, which is the only thing
we could do.
If absorbed, then we can run the diff from the submodule's absorbed
git dir (.git/modules/sm2). In practice, that's a bit more
complicated, because `git diff` expects to be run from inside a
working directory, not a git dir. So it looks in the config for
core.worktree, and does chdir("../../../sm2"), which is the very dir
that we're trying to avoid visiting because it's been deleted. We
work around this by setting GIT_WORK_TREE (and GIT_DIR) to ".". It is
little weird to set GIT_WORK_TREE to something that is not a working
tree just to avoid an unnecessary chdir, but it works.

Add a new "add-config" subcommand to `git submodule--helper` with the

`git submodule add` into C code. This new subcommand sets the
configuration variables of a newly added submodule, by registering the
url in local git config, as well as the submodule name and path in the
.gitmodules file. It also sets 'submodule.<name>.active' to "true" if
the submodule path has not already been covered by any pathspec
specified in 'submodule.active'.
This is meant to be a faithful conversion from shell to C, although we
add comments to areas that could be improved in future patches, after
the conversion has settled.

"git diff" showed a submodule working tree with untracked cruft as
"Submodule commit <objectname>-dirty", but a natural expectation is
that the "-dirty" indicator would align with "git describe --dirty",
which does not consider having untracked files in the working tree
as source of dirtiness. The inconsistency has been fixed.
* sj/untracked-files-in-submodule-directory-is-not-dirty:
diff: do not show submodule with untracked files as "-dirty"
A regression has been introduced by a62387b (submodule.c: fetch in
submodules git directory instead of in worktree, 2018-11-28).
The scenario in which it triggers is when one has a repository with a
submodule inside a submodule like this:
superproject/middle_repo/inner_repo
Person A and B have both a clone of it, while Person B is not working
with the inner_repo and thus does not have it initialized in his working
copy.
Now person A introduces a change to the inner_repo and propagates it
through the middle_repo and the superproject.
Once person A pushed the changes and person B wants to fetch them using
"git fetch" at the superproject level, B's git call will return with
error saying:
Could not access submodule 'inner_repo'
Errors during submodule fetch:
middle_repo
Expectation is that in this case the inner submodule will be recognized
as uninitialized submodule and skipped by the git fetch command.
This used to work correctly before 'a62387b (submodule.c: fetch in
submodules git directory instead of in worktree, 2018-11-28)'.
Starting with a62387b the code wants to evaluate "is_empty_dir()" inside
.git/modules for a directory only existing in the worktree, delivering
then of course wrong return value.
This patch ensures is_empty_dir() is getting the correct path of the
uninitialized submodule by concatenation of the actual worktree and the
name of the uninitialized submodule.
The first attempt to fix this regression, in 1b7ac4e6d4 (submodules:
fix of regression on fetching of non-init subsub-repo, 2020-11-12), by
simply reverting a62387b, resulted in an infinite loop of submodule
fetches in the simpler case of a recursive fetch of a superproject with
uninitialized submodules, and so this commit was reverted in 7091499bc0
(Revert "submodules: fix of regression on fetching of non-init
subsub-repo", 2020-12-02).
To prevent future breakages, also add a regression test for this
scenario.

tree has untracked files, to make it consistent with `git
describe --dirty` that is run in the submodule working tree.

There are two functions to get a single config string:
- git_config_get_string()
- git_config_get_string_const()
One might naively think that the first one allocates a new string and
the second one just points us to the internal configset storage. But
in fact they both allocate a new copy; the second one exists only to
avoid having to cast when using it with a const global which we never
intend to free.
The documentation for the function explains that clearly, but it seems
I'm not alone in being surprised by this. Of 17 calls to the function,
13 of them leak the resulting value.
We could obviously fix these by adding the appropriate free(). But it
would be simpler still if we actually had a non-allocating way to get
the string. There's git_config_get_value() but that doesn't quite do
what we want. If the config key is present but is a boolean with no
value (e.g., "[foo]bar" in the file), then we'll get NULL (whereas the
string versions will print an error and die).
So let's introduce a new variant, git_config_get_string_tmp(), that
behaves as these callers expect. We need a new name because we have new
semantics but the same function signature (so even if we converted the
four remaining callers, topics in flight might be surprised). The "tmp"
is because this value should only be held onto for a short time. In
practice it's rare for us to clear and refresh the configset,
invalidating the pointer, but hopefully the "tmp" makes callers think
about the lifetime. In each of the converted cases here the value only
needs to last within the local function or its immediate caller.

this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts all of the remaining files, as the resulting diff is
reasonably sized.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
We'll deal with any indentation/style fallouts separately.

This requires updating #include lines across the code-base, but that's
all fairly mechanical, and was done with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe 's/argv-array.h/strvec.h/'

In show_submodule_header(), we gather the left and right commits
of the submodule repository, as well as the merge bases. However,
prepare_submodule_summary() initializes the rev_info with the_repository,
so we end up parsing the commit in the wrong repository.
This results in a fatal error in parse_commit_in_graph(), since the
passed item does not belong to the repository's commit graph.

Code cleanup.
* jk/oid-array-cleanups:
oidset: stop referring to sha1-array
ref-filter: stop referring to "sha1 array"
bisect: stop referring to sha1_array
test-tool: rename sha1-array to oid-array
oid_array: rename source file from sha1-array
oid_array: use size_t for iteration
oid_array: use size_t for count and allocation
We renamed the actual data structure in 910650d2f8 (Rename sha1_array to
oid_array, 2017-03-31), but the file is still called sha1-array. Besides
being slightly confusing, it makes it more annoying to grep for leftover
occurrences of "sha1" in various files, because the header is included
in so many places.
Let's complete the transition by renaming the source and header files
(and fixing up a few comment references).
I kept the "-" in the name, as that seems to be our style; cf.
fc1395f4a4 (sha1_file.c: rename to use dash in file name, 2018-04-10).
We also have oidmap.h and oidset.h without any punctuation, but those
are "struct oidmap" and "struct oidset" in the code. We _could_ make
this "oidarray" to match, but somehow it looks uglier to me because of
the length of "array" (plus it would be a very invasive patch for little
gain).

Together with the previous commits, this commit fully fixes the problem
of using shared buffer for `real_path()` in `get_superproject_working_tree()`.
