8e2af8f0db difftool: remove an unnecessary call to strbuf_release()
The `buf` strbuf is reused again later in the same function, so there
is no benefit to calling strbuf_release(). The subsequent usage is
already using strbuf_reset() to reset the buffer, so releasing it
early is only going to lead to a wasteful reallocation.

Remove the early call to strbuf_release(). The same strbuf is already
cleaned up in the "finish:" section so nothing is leaked, either.

2255c80c91 difftool: refactor dir-diff to write files using helper functions
Add a helpers function to handle the unlinking and writing
of the dir-diff submodule and symlink stand-in files.

Use the helpers to implement the guts of the hashmap loops.
This eliminate duplicate code and safeguards the submodules
hashmap loop against the symlink-chasing behavior that 5bafb3576a
(difftool: fix symlink-file writing in dir-diff mode, 2021-09-22)
addressed.

The submodules loop should not strictly require the unlink() call that
this is introducing to them, but it does not necessarily hurt them
either beyond the cost of the extra unlink().

4ac9f15492 difftool: create a tmpdir path without repeated slashes
The paths generated by difftool are passed to user-facing diff tools.
Using paths with repeated slashes in them is a cosmetic blemish that
is exposed to users and can be avoided.

Use a strbuf to create the buffer used for the dir-diff tmpdir.
Strip trailing slashes from the value read from TMPDIR to avoid
repeated slashes in the generated paths.

returning -1 to cmd_main().

93d2c16041 mv: refuse to move sparse paths
Since cmd_mv() does not operate on cache entries and instead directly
checks the filesystem, we can only use path_in_sparse_checkout() as a
mechanism for seeing if a path is sparse or not. Be sure to skip
returning a failure if '-k' is specified.

To ensure that the advice around sparse paths is the only reason a move
failed, be sure to check this as the very last thing before inserting
into the src_for_dst list.

The tests cover a variety of cases such as whether the target is tracked
or untracked, and whether the source or destination are in or outside of
the sparse-checkout definition.

d7c4415e55 rm: skip sparse paths with missing SKIP_WORKTREE
If a path does not match the sparse-checkout cone but is somehow missing
the SKIP_WORKTREE bit, then 'git rm' currently succeeds in removing the
file. One reason a user might be in this situation is a merge conflict
outside of the sparse-checkout cone. Removing such a file might be
problematic for users who are not sure what they are doing.

Add a check to path_in_sparse_checkout() when 'git rm' is checking if a
path should be considered for deletion. Of course, this check is ignored
if the '--sparse' option is specified, allowing users who accept the
risks to continue with the removal.

This also removes a confusing behavior where a user asks for a directory
to be removed, but only the entries that are within the sparse-checkout
definition are removed. Now, 'git rm <dir>' will fail without '--sparse'
and will succeed in removing all contained paths with '--sparse'.

0299a69694 add: implement the --sparse option
We previously modified 'git add' to refuse updating index entries
outside of the sparse-checkout cone. This is justified to prevent users
from accidentally getting into a confusing state when Git removes those
files from the working tree at some later point.

Unfortunately, this caused some workflows that were previously possible
to become impossible, especially around merge conflicts outside of the
sparse-checkout cone. These were documented in tests within t1092.

We now re-enable these workflows using a new '--sparse' option to 'git
add'. This allows users to signal "Yes, I do know what I'm doing with
these files," and accept the consequences of the files leaving the
worktree later.

We delay updating the advice message until implementing a similar option
in 'git rm' and 'git mv'.

49fdd51a23 add: skip tracked paths outside sparse-checkout cone
When 'git add' adds a tracked file that is outside of the
sparse-checkout cone, it checks the SKIP_WORKTREE bit to see if the file
exists outside of the sparse-checkout cone. This is usually correct,
except in the case of a merge conflict outside of the cone.

Modify add_pathspec_matched_against_index() to be more careful about
paths by checking the sparse-checkout patterns in addition to the
SKIP_WORKTREE bit. This causes 'git add' to no longer allow files
outside of the cone that removed the SKIP_WORKTREE bit due to a merge
conflict.

With only this change, users will only be able to add the file after
adding the file to the sparse-checkout cone. A later change will allow
users to force adding even though the file is outside of the
sparse-checkout cone.

105e8b014b add: fail when adding an untracked sparse file
The add_files() method in builtin/add.c takes a set of untracked files
that are being added by the input pathspec and inserts them into the
index. If these files are outside of the sparse-checkout cone, then they
gain the SKIP_WORKTREE bit at some point. However, this was not checked
before inserting into the index, so these files are added even though we
want to avoid modifying the index outside of the sparse-checkout cone.

Add a check within add_files() for these files and write the advice
about files outside of the sparse-checkout cone.

This behavior change modifies some existing tests within t1092. These
tests intended to document how a user could interact with the existing
behavior in place. Many of these tests need to be marked as expecting
failure. A future change will allow these tests to pass by adding a flag
to 'git add' that allows users to modify index entries outside of the
sparse-checkout cone.

The 'submodule handling' test is intended to document what happens to
directories that contain a submodule when the sparse index is enabled.
It is not trying to say that users should be able to add submodules
outside of the sparse-checkout cone, so that test can be modified to
avoid that operation.

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.

67985e4e4a refs: drop "broken" flag from for_each_fullref_in()
No callers pass in anything but "0" here. Likewise to our sibling
functions. Note that some of them ferry along the flag, but none of
their callers pass anything but "0" either.

Nor is anybody likely to change that. Callers which really want to see
all of the raw refs use for_each_rawref(). And anybody interested in
iterating a subset of the refs will likely be happy to use the
now-default behavior of showing broken refs, but omitting dangling
symlinks.

So we can get rid of this whole feature.

1763334caf ref-filter: stop setting FILTER_REFS_INCLUDE_BROKEN
Of the ref-filter callers, for-each-ref and git-branch both set the
INCLUDE_BROKEN flag (but git-tag does not, which is a weird
inconsistency).  But now that GIT_REF_PARANOIA is on by default, that
produces almost the same outcome for all three.

The one exception is that GIT_REF_PARANOIA will omit dangling symrefs.
That's a better behavior for these tools, as they would never include
such a symref in the main output anyway (they can't, as it doesn't point
to an object). Instead they issue a warning to stderr. But that warning
is somewhat useless; a dangling symref is a perfectly reasonable thing
to have in your repository, and is not a sign of corruption. It's much
friendlier to just quietly ignore it.

And in terms of robustness, the warning gains us little. It does not
impact the exit code of either tool. So while the warning _might_ clue
in a user that they have an unexpected broken symref, it would not help
any kind of scripted use.

This patch converts for-each-ref and git-branch to stop using the
INCLUDE_BROKEN flag. That gives them more reasonable behavior, and
harmonizes them with git-tag.

We have to change one test to adapt to the situation. t1430 tries to
trigger all of the REF_ISBROKEN behaviors from the underlying ref code.
It uses for-each-ref to do so (because there isn't any other mechanism).
That will no longer issue a warning about the symref which points to an
invalid name, as it's considered dangling (and we can instead be sure
that it's _not_ mentioned on stderr). Note that we do still complain
about the illegally named "broken..symref"; its problem is not that it's
dangling, but the name of the symref itself is illegal.

5d1f5b8cd4 repack, prune: drop GIT_REF_PARANOIA settings
Now that GIT_REF_PARANOIA is the default, we don't need to selectively
enable it for destructive operations. In fact, it's harmful to do so,
because it overrides any GIT_REF_PARANOIA=0 setting that the user may
have provided (because they're trying to work around some corruption).

With these uses gone, we can further clean up the ref_paranoia global,
and make it a static variable inside the refs code.

In 73c3253d75 (bundle: framework for options before bundle file,

However, nothing ever did anything with this "verbose" variable, and

escaped the lab, and wasn't flagged by reviewers at the time. Let's

5bafb3576a difftool: fix symlink-file writing in dir-diff mode
The difftool dir-diff mode handles symlinks by replacing them with their
readlink(2) values. This allows diff tools to see changes to symlinks
as if they were regular text diffs with the old and new path values.
This is analogous to what "git diff" displays when symlinks change.

The temporary diff directories that are created initially contain
symlinks because they get checked-out using a temporary index that
retains the original symlinks as checked-in to the repository.

A bug was introduced when difftool was rewritten in C that made
difftool write the readlink(2) contents into the pointed-to file rather
than the symlink itself. The write was going through the symlink and
writing to its target rather than writing to the symlink path itself.

Replace symlinks with raw text files by unlinking the symlink path
before writing the readlink(2) content into them.

When 18ec800512 (difftool: handle modified symlinks in dir-diff mode,
2017-03-15) added handling for modified symlinks this bug got recorded
in the test suite. The tests included the pointed-to symlink target
paths. These paths were being reported because difftool was erroneously
writing to them, but they should have never been reported nor written.

Correct the modified-symlinks test cases by removing the target files
from the expected output.

Add a test to ensure that symlinks are written with the readlink(2)
values and that the target files contain their original content.

7740ac691d rebase: dereference tags
A rebase started with 'git rebase <A> <B>' is conceptually to first
checkout <B> and run 'git rebase <A>' starting from that state.  'git
rebase --abort' in the middle of such a rebase should take us back to
the state we checked out <B>.

This used to work, even when <B> is a tag that points at a commit,
until Git 2.20.0 when the command was reimplemented in C.  The command
now complains that the tag object itself cannot be checked out, which
may be technically correct but is not what the user asked to do.

Fix this old regression by using lookup_commit_reference_by_name()
when parsing <B>. The scripted version did not need to peel the tag
because the commands it passed the tag to (e.g 'git reset') peeled the
tag themselves.

1d188263e0 rebase: use lookup_commit_reference_by_name()
peel_committish() appears to have been copied from the scripted rebase
but it duplicates the functionality of
lookup_commit_reference_by_name() so lets use that instead.
