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).

Normally diffs will contain a hunk header of the format
"@@ -2,2 +2,15 @@ code". However when there is only 1 line of
change, the unified diff format allows for the second comma
separated value to be omitted in either before or after
line counts.
This can produce hunk headers that look like
"@@ -2 +2,18 @@ code" or "@@ -2,2 +2 @@ code".
As a result, scan_hunk_header mistakenly returns the line
number as line count, which then results in unpredictable
parsing errors with the rest of the patch, including giving
multiple lines of output for a single commit.
Fix by explicitly setting line count to 1 when there is
no comma, and add a test.
apply.c contains this same logic except it is correct. A
worthwhile future project might be to unify these two diff
parsers so they both benefit from fixes.

Since some callers may want to send warning messages to somewhere other
than stdout/stderr, stop printing "warning: Cannot merge binary files"
from ll-merge and instead modify the return status of ll_merge() to
indicate when a merge of binary files has occurred. Message printing
probably does not belong in a "low-level merge" anyway.
This commit continues printing the message as-is, just from the callers
instead of within ll_merge(). Future changes will start handling the
message differently in the merge-ort codepath.
There was one special case here: the callers in rerere.c do NOT check
for and print such a message; since those code paths explicitly skip
over binary files, there is no reason to check for a return status of
LL_MERGE_BINARY_CONFLICT or print the related message.
Note that my methodology included first modifying ll_merge() to return
a struct, so that the compiler would catch all the callers for me and
ensure I had modified all of them. After modifying all of them, I then
changed the struct to an enum.

The --remerge-diff option will need to create new blobs and trees
representing the "automatic merge" state. If one is traversing a
long project history, one can easily get hundreds of thousands of
loose objects generated during `log --remerge-diff`. However, none of
those loose objects are needed after we have completed our diff
operation; they can be summarily deleted.
Add a new helper function to tmp_objdir to discard all the contained
objects, and call it after each merge is handled.

When this option is specified, we remerge all (two parent) merge commits
and diff the actual merge commit to the automatically created version,
in order to show how users removed conflict markers, resolved the
different conflict versions, and potentially added new changes outside
of conflict regions in order to resolve semantic merge problems (or,
possibly, just to hide other random changes).
This capability works by creating a temporary object directory and
marking it as the primary object store. This makes it so that any blobs
or trees created during the automatic merge are easily removable
afterwards by just deleting all objects from the temporary object
directory.
There are a few ways that this implementation is suboptimal:
* `log --remerge-diff` becomes slow, because the temporary object
directory can fill with many loose objects while running
* the log output can be muddied with misplaced "warning: cannot merge
binary files" messages, since ll-merge.c unconditionally writes those
messages to stderr while running instead of allowing callers to
manage them.
* important conflict and warning messages are simply dropped; thus for
conflicts like modify/delete or rename/rename or file/directory which
are not representable with content conflict markers, there may be no
way for a user of --remerge-diff to know that there had been a
conflict which was resolved (and which possibly motivated other
changes in the merge commit).
* when fixing the previous issue, note that some unimportant conflict
and warning messages might start being included. We should instead
make sure these remain dropped.
Subsequent commits will address these issues.

When pushing a hidden ref, e.g.:
$ git push origin HEAD:refs/hidden/foo
"receive-pack" will reject our request with an error message like this:
! [remote rejected] HEAD -> refs/hidden/foo (deny updating a hidden ref)
The remote side ("git-receive-pack") will not create the hidden ref as
expected, but the pack file sent by "git-send-pack" is left inside the
remote repository. I.e. the quarantine directory is not purged as it
should be.
Add a checkpoint before calling "tmp_objdir_migrate()" and after calling
the "pre-receive" hook to purge that temporary data in the quarantine
area when there is no command ready to run.
The reason we do not add the checkpoint before the "pre-receive" hook,
but after it, is that the "pre-receive" hook is called with a switch-off
"skip_broken" flag, and all commands, even broken ones, should be fed
by calling "feed_receive_hook()".

This parameter is only needed when a ref is going to be updated and

only discarding uncommitted changes in the working tree such as such
as "rebase --skip" or create_autostash() do not update any refs so
should not have to worry about passing this parameter.
This change is not intended to have any user visible changes. The
pointer comparison between `oid` and `&head_oid` checks that the
caller did not pass an oid to be checked out. As no callers pass
RESET_HEAD_RUN_POST_CHECKOUT_HOOK without passing an oid there are
no changes to when the post-checkout hook is run. As update_ref() only
updates the ref if the oid passed to it differs from the current ref
there are no changes to when HEAD is updated.

"reset" so that the error messages match the builtin reset command
like all the other callers that are doing a reset. The case that

When run from a non-main worktree, setup_git_directory() will note
that the discovered git directory

DEFAULT_GIT_DIR_ENVIRONMENT (see setup_discovered_git_dir()), and
decide to set GIT_DIR in the environment. This matters because...
Whenever git is run with the GIT_DIR environment variable set, and
GIT_WORK_TREE not set, it presumes that '.' is the working tree. So...
This combination results in the subcommand being very confused about
the working tree. Fix it by also setting the GIT_WORK_TREE environment
variable along with setting cmd.dir.
A possibly more involved fix we could consider for later would be to
make setup.c set GIT_WORK_TREE whenever (a) it discovers both the git
directory and the working tree and (b) it decides to set GIT_DIR in the
environment. I did not attempt that here as such would be too big of a

When cloning a branchless and tagless but not refless remote using

list. This makes the clone fail with the message "remote transport

Git should have refrained from calling transport_fetch_refs(), just like
it does in the case that the remote is refless. Therefore, teach Git to
do this.
In protocol v2, this does not happen because the client passes
ref-prefix arguments that filter out non-branches and non-tags in the
ref advertisement, making the remote appear empty.

When 9081a421 (checkout: fix "branch info" memory leaks, 2021-11-16)

to ensure that a local branch is truly local and not a symref to

ways. First of all, such a tightening did not belong to a leak-fix
patch. And the condition it detected was *not* a bug in our program
but a problem in user data, where warning() or die() would have been
more appropriate.
As the condition is not fatal (the result of computing the local
branch name in the code that is involved in the faulty check is only
used as a textual label for the commit), let's revert the code to
the original state, i.e. strip "refs/heads/" to compute the local
branch name if possible, and otherwise leave it NULL. The consumer
of the information in merge_working_tree() is prepared to see NULL
in there and act accordingly.

`git fetch --negotiate-only` is an implementation detail of push
negotiation and, unlike most `git fetch` invocations, does not actually
update the main repository. Thus it should not update submodules even
if submodule recursion is enabled.
This is not just slow, it is wrong e.g. push negotiation with
"submodule.recurse=true" will cause submodules to be updated because it
invokes `git fetch --negotiate-only`.
Fix this by disabling submodule recursion if --negotiate-only was given.
Since this makes --negotiate-only and --recurse-submodules incompatible,
check for this invalid combination and die.

Speed up cmd_fetch() by bailing out early if we know for certain that
objects will not be fetched. cmd_fetch() can bail out early whenever

"git branch -h" incorrectly said "--track[=direct|inherit]",
implying that "--trackinherit" is a valid option, which has been
corrected.

branch,checkout: fix --track usage strings
As Ævar pointed out in [1], the use of PARSE_OPT_LITERAL_ARGHELP with a
list of allowed parameters is not recommended. Both git-branch and
git-checkout were changed in d311566 (branch: add flags and config to
inherit tracking, 2021-12-20) to use this discouraged combination for
their --track flags.
Fix this by removing PARSE_OPT_LITERAL_ARGHELP, and changing the arghelp
to simply be "mode". Users may discover allowed values in the manual
pages.

"pull --rebase" internally uses the merge machinery when the other
history is a descendant of ours (i.e. perform fast-forward). This
came from [1], where the discussion was started from a feature
request to do so. It is a bit hard to read the rationale behind it
in the discussion, but it seems that it was an established fact for
everybody involved that does not even need to be mentioned that
fast-forwarding done with "rebase" was much undesirable than done
with "merge", and more importantly, the result left by "merge" is as
good as (or better than) that by "rebase".
Except for one thing. Because "git merge" does not (and should not)
honor rebase.autostash, "git pull" needs to read it and forward it
when we use "git merge" as a (hopefully better) substitute for "git
rebase" during the fast-forwarding. But we forgot to do so (we only
add "--[no-]autostash" to the "git merge" command when "git pull" itself
was invoked with "--[no-]autostash" command line option.
Make sure "git merge" is run with "--autostash" when
rebase.autostash is set and used to fast-forward the history on
behalf of "git rebase". Incidentally this change also takes care of
the case where
- "git pull --rebase" (without other command line options) is run
- "rebase.autostash" is not set
- The history fast-forwards
In such a case, "git merge" is run with an explicit "--no-autostash"
to prevent it from honoring merge.autostash configuration, which is
what we want. After all, we want the "git merge" to pretend as if
it is "git rebase" while being used for this purpose.

Replace unconditional index expansion in 'do_reupdate()' with one scoped to
only where a full index is needed. A full index is only required in
'do_reupdate()' when a sparse directory in the index differs from HEAD; in
that case, the index is expanded and the operation restarted.
Because the index should only be expanded if a sparse directory is modified,
add a test ensuring the index is not expanded when differences only exist
within the sparse cone.

Enable use of the sparse index with `update-index`. Most variations of
`update-index` work without explicitly expanding the index or making any
other updates in or outside of `update-index.c`.
The one usage requiring additional changes is `--cacheinfo`; if a file
inside a sparse directory was specified, the index would not be expanded
until after the cache tree is invalidated, leading to a mismatch between the
index and cache tree. This scenario is handled by rearranging
`add_index_entry_with_check`, allowing `index_name_stage_pos` to expand the
index *before* attempting to invalidate the relevant cache tree path,
avoiding cache tree/index corruption.

Add repository settings to allow usage of the sparse index.
When using the `--all` option, sparse directories are ignored by default due
to the `skip-worktree` flag, so there is no need to expand the index. If
`--ignore-skip-worktree-bits` is specified, the index is expanded in order
to check out all files.
When checking out individual files, existing behavior in a full index is to
exit with an error if a directory is specified (as the directory name will
not match an index entry). However, it is possible in a sparse index to
match a directory name to a sparse directory index entry, but checking out
that sparse directory still results in an error on checkout. To reduce some
potential confusion for users, `checkout_file(...)` explicitly exits with an
informative error if provided with a sparse directory name. The test
corresponding to this scenario verifies the error message, which now differs
between sparse index and non-sparse index checkouts.

Update `checkout-index` to no longer refresh files that have the
`skip-worktree` bit set, exiting with an error if `skip-worktree` filenames
are directly provided to `checkout-index`. The newly-added
`--ignore-skip-worktree-bits` option provides a mechanism to replicate the
old behavior, checking out *all* files specified (even those with
`skip-worktree` enabled).
The ability to toggle whether files should be checked-out based on
`skip-worktree` already exists in `git checkout` and `git restore` (both of
which have an `--ignore-skip-worktree-bits` option). The change to, by
default, ignore `skip-worktree` files is especially helpful for
sparse-checkout; it prevents inadvertent creation of files outside the
sparse definition on disk and eliminates the need to expand a sparse index
when using the `--all` option.
Internal usage of `checkout-index` in `git stash` and `git filter-branch` do
not make explicit use of files with `skip-worktree` enabled, so
`--ignore-skip-worktree-bits` is not added to them.

Remove full index requirement for `git clean` and test to ensure the index
is not expanded in `git clean`. Add to existing test for `git clean` to
verify cleanup of untracked files in sparse directories is consistent
between sparse index and non-sparse index checkouts.
