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'.

Some of the rules for using COPY_ARRAY instead of memcpy with sizeof are
intended to reduce the number of sizeof variants to deal with. They can
have unintended side effects if only they match, but not the one for the
COPY_ARRAY conversion at the end.
Avoid these side effects by instead using a self-contained rule for each
combination of array and pointer for source and destination which lists
all sizeof variants inline.
This lets "make contrib/coccinelle/array.cocci.patch" take 15% longer on
my machine, but gives peace of mind that no incomplete transformation
will be generated.

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'.

Add a helper to grow an array. This is analogous to ALLOC_GROW() in
the rest of the codebase but returns −1 on allocation failure to
accommodate other users of libxdiff such as libgit2. It will also
return a error if the multiplication overflows while calculating the
new allocation size. Note that this keeps doubling on reallocation
like the code it is replacing rather than increasing the existing size
by half like ALLOC_GROW(). It does however copy ALLOC_GROW()'s trick
of adding a small amount to the new allocation to avoid a lot of
reallocations at small sizes.
Note that xdl_alloc_grow_helper() uses long rather than size_t for
`nr` and `alloc` to match the existing code.

Usually clone tries to use the same local HEAD as the remote (unless the
user has given --branch explicitly). Even if the remote HEAD is detached
or unborn, we can detect those situations with modern versions of Git.
If the remote is too old to support the "unborn" extension (or it has
been disabled via config), then we can't know the name of the remote's
unborn HEAD, and we fall back whatever the local default branch name is
configured to be.
But that leads to one weird corner case. It's rare because it needs a
number of factors:
- the remote has an unborn HEAD
- the remote is too old to support "unborn", or has disabled it
- the remote has another branch "foo"
- the local default branch name is "foo"
In that case you end up with a local clone on an unborn "foo" branch,
disconnected completely from the remote's "foo". This is rare in
practice, but the result is quite confusing.
When choosing "foo", we can double check whether the remote has such a
name, and if so, start our local "foo" at the same spot, rather than
making it unborn.
Note that this causes a test failure in t5605, which is cloning from a
bundle that doesn't contain HEAD (so it behaves like a remote that
doesn't support "unborn"), but has a single "main" branch. That test
expects that we end up in the weird "unborn main" case, where we don't
actually check out the remote branch of the same name. Even though we
have to update the test, this seems like an argument in favor of this
patch: checking out main is what I'd expect from such a bundle.
So this patch updates the test for the new behavior and adds an adjacent
one that checks what the original was going for: if there's no HEAD and
the bundle _doesn't_ have a branch that matches our local default name,
then we end up with nothing checked out.

Unless "--branch" was given, clone generally tries to match the local
HEAD to the remote one. For most repositories, this is easy: the remote
tells us which branch HEAD was pointing to, and we call our local
checkout() function on that branch.
When cloning an empty repository, it's a little more tricky: we have
special code that checks the transport's "unborn" extension, or falls back
to our local idea of what the default branch should be. In either case,
we point the new HEAD to that, and set up the branch.* config.
But that leaves one case unhandled: when the remote repository _isn't_
empty, but its HEAD is unborn. The checkout() function is smart enough
to realize we didn't fetch the remote HEAD and it bails with a warning.
But we'll have ignored any information the remote gave us via the unborn
extension. This leads to nonsense outcomes:
- If the remote has its HEAD pointing to an unborn "foo" and contains
another branch "bar", cloning will get branch "bar" but leave the
local HEAD pointing at "master" (or whatever our local default is),
which is useless. The project does not use "master" as a branch.
- Worse, if the other branch "bar" is instead called "master" (but
again, the remote HEAD is not pointing to it), then we end up with a
local unborn branch "master", which is not connected to the remote
"master" (it shares no history, and there's no branch.* config).
Instead, we should try to use the remote's HEAD, even if its unborn, to
be consistent with the other cases.
The reason this case was missed is that cmd_clone() handles empty and
non-empty repositories on two different sides of a conditional:
if (we have any refs) {
fetch refs;
check for --branch;
otherwise, try to point our head at remote head;
otherwise, our head is NULL;
} else {
check for --branch;
otherwise, try to use "unborn" extension;
otherwise, fall back to our default name name;
}
So the smallest change would be to repeat the "unborn" logic at the end
of the first block. But we can note some other overlaps and
inconsistencies:
- both sides have to handle --branch (though note that it's always an
error for the empty repo case, since an empty repo by definition
does not have a matching branch)
- the fall back to the default name is much more explicit in the
empty-repo case. The non-empty case eventually ends up bailing
from checkout() with a warning, which produces a similar result, but
fails to set up the branch config we do in the empty case.
So let's pull the HEAD setup out of this conditional entirely. This
de-duplicates some of the code and the result is easy to follow, because
helper functions like find_ref_by_name() do the right thing even in the
empty-repo case (i.e., by returning NULL).
There are two subtleties:
- for a remote with a detached HEAD, it will advertise an oid for HEAD
(which we store in our "remote_head" variable), but we won't find a
matching refname (so our "remote_head_points_at" is NULL). In this
case we make a local detached HEAD to match. Right now this happens
implicitly by reaching update_head() with a non-NULL remote_head
(since we skip all of the unborn-fallback). We'll now need to
account for it explicitly before doing the fallback.
- for an empty repo, we issue a warning to the user that they've
cloned an empty repo. The text of that warning doesn't make sense
for a non-empty repo with an unborn HEAD, so we'll have to
differentiate the two cases there. We could just use different text,
but instead let's allow the code to continue down to checkout(),
which will issue an appropriate warning, like:
remote HEAD refers to nonexistent ref, unable to checkout
Continuing down to checkout() will make it easier to do more fixes
on top (see below).
Note that this patch fixes the case where the other side reports an
unborn head to us using the protocol extension. It _doesn't_ fix the
case where the other side doesn't tell us, we locally guess "master",
and the other side happens to have a "master" which its HEAD doesn't
point. But it doesn't make anything worse there, and it should actually
make it easier to fix that problem on top.

We don't need to put a "\n" in calls to warning(), since it adds one
itself (and the user sees an extra blank line). Drop it, and while we're
here, drop the full-stop from the message, which goes against our
guidelines.
This bug dates all the way back to 8434c2f1af (Build in clone,
2008-04-27), but presumably nobody noticed because it's hard to trigger:
you have to clone a repository whose HEAD is unborn, but which is not
otherwise empty.

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
the strbuf in the same function.
See the tests in contrib/coccinelle/tests/unused.{c,res} for what it's
intended to find and replace.
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.

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.

Add test for "mv: add check_dir_in_index() and solve general dir check
issue" in this series.
This change tests the following:
1. mv <source> as a directory on the sparse index boundary (where it
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).
These tests can be written now for correctness, but later the first case
can be updated to use the 'ensure_not_expanded' helper in t1092.

Add corresponding tests to test following situations:
We do not have sufficient coverage of moving files outside
of a sparse-checkout cone. Create new tests covering this
behavior, keeping in mind that the user can include --sparse
(or not), move a file or directory, and the destination can
already exist in the index (in this case user can use --force
to overwrite existing entry).

Fix memory leaks introduced with these tests in f1294eaf7fb (bloom.c:

can mark almost the entirety of t0095-bloom.sh as passing with
SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true", there's still an
unrelated memory leak in "git commit" in one of the tests, let's skip
that one under SANITIZE_LEAK for now.

Fix memory leaks in "test-tool regex" which have been there since
c91841594c2 (test-regex: Add a test to check for a bug in the regex
routines, 2012-09-01), as a result we can mark a test as passing with
SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true".
We could regfree() on the die() paths here, which would make some
invocations of valgrind(1) happy, but let's just target SANITIZE=leak
for now. Variables that are still reachable when we die() are not
reported as leaks.

Fix a memory leak introduced in 44c175c7a46 (pull: error on no merge
candidates, 2015-06-18). As a result we can mark several tests as
passing with SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true".
Removing the "int ret = 0" assignment added here in a6d7eb2c7a6 (pull:
optionally rebase submodules (remote submodule changes only),
2017-06-23) is not a logic error, it could always have been left
uninitialized (as "int ret"), now that we'll use the "ret" from the
upper scope we can drop the assignment in the "opt_rebase" branch.

Fix a memory leak where "cat-file" will leak the "path" member. See
e5fba602e59 (textconv: support for cat_file, 2010-06-15) for the code
that introduced the offending get_oid_with_context() call (called
get_sha1_with_context() at the time).
As a result we can mark several tests as passing with SANITIZE=leak
using "TEST_PASSES_SANITIZE_LEAK=true".
As noted in dc944b65f1d (get_sha1_with_context: dynamically allocate
oc->path, 2017-05-19) callers must free the "path" member. That same
commit added the relevant free() to this function, but we weren't
catching cases where we'd return early.

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.
Let's fix the memory leak, and avoid future issues by initializing the
"topts" with a helper function. There are no functional changes here.
