When reusing chunks verbatim from an existing source pack, the function
write_reused_pack() first attempts to reuse whole words (via the
function `write_reused_pack_verbatim()`), and then individual bits (via
`write_reused_pack_one()`).
In the non-MIDX case, all of this code works fine. Likewise, in the MIDX
case, processing bits individually from the first (preferred) pack works
fine. However, processing subsequent packs in the MIDX case is broken
when there are duplicate objects among the set of MIDX'd packs.
This is because we treat the individual bit positions as valid pack
positions within the source pack(s), which does not account for gaps in
the source pack, like we see when the MIDX must break ties between
duplicate objects which appear in multiple packs.
The broken code looks like:
for (; i < reuse_packfile_bitmap->word_alloc; i++) {
for (offset = 0; offset < BITS_IN_EWORD, offset++) {
/* ... */
write_reused_pack_one(reuse_packfile->p,
pos + offset - reuse_packfile->bitmap_pos,
f, pack_start, &w_curs);
}
}
, where the second argument is incorrect and does not account for gaps.
Instead, make sure that we translate bit positions in the MIDX's
pseudo-pack order to pack positions in the respective source packs by:
- Translating the bit position (pseudo-pack order) to a MIDX position
(lexical order).
- Use the MIDX position to obtain the offset at which the given object
occurs in the source pack.
- Then translate that offset back into a pack relative position within
the source pack by calling offset_to_pack_pos().
After doing this, then we can safely use the result as a pack position.
Note that when doing single-pack reuse, as well as reusing objects from
the MIDX's preferred pack, such translation is not necessary, since
either ties are broken in favor of the preferred pack, or there are no
ties to break at all (in the case of non-MIDX bitmaps).
Failing to do this can result in strange failure modes. One example that
can occur when misinterpreting bits in the above fashion is that Git
thinks it's supposed to send a delta that the caller does not want.
Under this (incorrect) assumption, we try to look up the delta's base
(so that we can patch any OFS_DELTAs if necessary). We do this using
find_reused_offset().
But if we try and call that function for an offset belonging to an
object we did not send, we'll get back garbage. This can result in us
computing a negative fixup value, which results in memory corruption
when trying to write the (patched) OFS_DELTA header.

The next commit will need to use the bitmap's MIDX (if one exists) to
translate bit positions into pack-relative positions in the source pack.
Ordinarily, we'd use the "midx" field of the bitmap_index struct. But
since that struct is defined within pack-bitmap.c, and our caller is in
a separate compilation unit, we do not have access to the MIDX field.
Instead, add a "from_midx" field to the bitmapped_pack structure so that
we can use that piece of data from outside of pack-bitmap.c. The caller
that uses this new piece of information will be added in the following
commit.

In our tests for multi-pack reuse, we have two helper functions:
- test_pack_objects_reused_all(), and
- test_pack_objects_reused()
which invoke pack-objects (either with `--all`, or the supplied tips via
stdin, respectively) and ensure that (a) the number of reused objects,
and (b) the number of packs which those objects were reused from both
match the expected values.
Both functions discard the output of pack-objects and assert only on the
contents of the trace2 stream.
However, if we store the pack and attempt to index it with `--strict`,
we find that a number of our tests are broken, indicating a bug within
multi-pack reuse.
That bug will be addressed in a subsequent commit. But let's first
harden these tests by trying to index the resulting pack, marking the
tests which fail appropriately.

helper/test-oid-array.c along with t0064-oid-array.sh test the
oid-array.h API, which provides storage and processing
efficiency over large lists of object identifiers.
Migrate them to the unit testing framework for better runtime
performance and efficiency. As we don't initialize a repository
in these tests, the hash algo that functions like oid_array_lookup()
use is not initialized, therefore call repo_set_hash_algo() to
initialize it. And init_hash_algo():lib-oid.c can aid in this
process, so make it public.

It was reported that git-verify-pack(1) has started to crash with Git
v2.46.0 when run outside of a repository. This is another fallout from
c8aed5e8da (repository: stop setting SHA1 as the default object hash,
2024-05-07), where we have stopped setting the default hash algorithm
for `the_repository`. Consequently, code that relies on `the_hash_algo`
will now crash when it hasn't explicitly been initialized, which may be
the case when running outside of a Git repository.
The crash is not in git-verify-pack(1) but instead in git-index-pack(1),
which gets called by the former. Ideally, both of these programs should
be able to identify the hash algorithm used by the packfile and index
without having to rely on external information. But unfortunately, the
format for neither of them is completely self-describing, so it is not
possible to derive that information. This is a design issue that we
should address by introducing a new packfile version that encodes its
object hash.
For now though the more important fix is to not make either of these
programs crash anymore, which we do by falling back to SHA1 when the
object hash is unconfigured. This pessimizes reading packfiles which
use a different hash than SHA1, but restores previous behaviour.

VSCode has supported three-way merges since 2022, see
<https://github.com/microsoft/vscode/issues/5770#issuecomment-1188658476>.
Although the program binary is located at /usr/bin/code, name the
mergetool "vscode" because the word "code" is too generic and would lead
to confusion. The name "vscode" also matches Git's existing
contrib/vscode directory.
On Windows, VSCode adds the directory that contains code.cmd to %PATH%,

If neither HAVE_DEV_TTY nor GIT_WINDOWS_NATIVE is set, the fallback
code calls the system getpass(). This unfortunately ignores the "echo"
boolean parameter, as we have no way to implement that functionality.
But we still have to keep the unused parameter, since our interface
has to match the other implementations.

In git-log we leave the save_commit_buffer flag set to "1", which tells
the commit parsing code to store the object content after it has parsed
it to find parents, tree, etc. That lets us reuse the contents for
pretty-printing the commit in the output. And then after printing each
commit, we call free_commit_buffer(), since we don't need it anymore.
But some options may cause us to traverse commits which are not part of
the output. And so git-log does not see them at all, and doesn't free
them. One such case is something like:
git log -n 1000 --skip=1000000
which will churn through a million commits, before showing only a
thousand. We loop through these inside get_revision(), without freeing
the contents. As a result, we end up storing the object data for those
million commits simultaneously.
We should free the stored buffers (if any) for those commits as we skip
over them, which is what this patch does. Running the above command in
linux.git drops the peak heap usage from ~1.1GB to ~200MB, according to
valgrind/massif. (I thought we might get an even bigger improvement, but
the remaining memory is going to commit/tree structs, which we do hold
on to forever).
Note that this problem doesn't occur if:
- you're running a git-rev-list without a --format parameter; it turns
off save_commit_buffer by default, since it only output the object
id
- you've built a commit-graph file, since in that case we'd use the
optimized graph data instead of the initial parse, and then do a
lazy parse for commits we're actually going to output
There are probably some other option combinations that can likewise
end up with useless stored commit buffers. For example, if you ask for
"foo..bar", then we'll have to walk down to the merge base, and
everything on the "foo" side won't be shown. Tuning the "save" behavior
to handle that might be tricky (I guess maybe drop buffers for anything
we mark as UNINTERESTING?). And in the long run, the right solution here
is probably to make sure the commit-graph is built (since it fixes the
memory problem _and_ drastically reduces CPU usage).
But since this "--skip" case is an easy one-liner, it's worth fixing in
the meantime. It should be OK to make this call even if there is no
saved buffer (e.g., because save_commit_buffer=0, or because a
commit-graph was used), since it's O(1) to look up the buffer and is a
noop if it isn't present. I verified by running the above command after
"git commit-graph write --reachable", and it takes the same time with
and without this patch.

We provide custom malloc/free callbacks for the pcre library to use.
Those take an extra "data" parameter, but we don't use it. Back when
these were added in 513f2b0bbd (grep: make PCRE2 aware of custom
allocator, 2019-10-16), we only had MAYBE_UNUSED.
But these days we have UNUSED, which we should prefer, as it will
let the compiler inform us if the code changes to actually use the
parameters.
I also moved the annotations to come after the variable name, which is
how we typically spell it.

The "opts" parameter is always used, so marking it with MAYBE_UNUSED is
just confusing.
This annotation goes back to 41abfe15d9 (maintenance: add pack-refs
task, 2021-02-09), when it really was unused. Back then we did not have
the UNUSED macro that would complain if the code changed to use the
parameter. So when we started using it in bfc2f9eb8e (builtin/gc:
forward git-gc(1)'s `--auto` flag when packing refs, 2024-03-25), nobody
noticed.

A function that uses a parameter in one build may lose all uses of

workaround for such a case, MAYBE_UNUSED, should also be mentioned
when we recommend the use of UNUSED to our developers.
Keep the addition to the guideline short and document the criteria
to choose between UNUSED and MAYBE_UNUSED near their definition.

Now that -Wunused-parameter is on by default for DEVELOPER=1 builds,
people may trigger it, blocking their build. When it's a mistake for the
parameter to exist, the path forward is obvious: remove it. But
sometimes you need to suppress the warning, and the "UNUSED" mechanism
for that is specific to our project, so people may not know about it.
Let's put some advice in CodingGuidelines, including an example warning
message. That should help people who grep for the warning text after
seeing it from the compiler.

Having now removed or annotated all of the unused function parameters in
our code base, I found that each instance falls into one of three
categories:
1. ignoring the parameter is a bug (e.g., a function takes a ptr/len
pair, but ignores the length). Detecting these helps us find the
bugs.
2. the parameter is unnecessary (and usually left over from a
refactoring or earlier iteration of a patches series). Removing
these cleans up the code.
3. the function has to conform to a specific interface (because it's
used via a function pointer, or matches something on the other side
of an #ifdef). These ones are annoying, but annotating them with
UNUSED is not too bad (especially if the compiler tells you about
the problem promptly).
Certainly instances of (3) are more common than (1), but after finding
all of these, I think there were enough cases of (1) that it justifies
the work in annotating all of the (3)s.
And since the code base is now at a spot where we compile cleanly with
-Wunused-parameter, turning it on will make it the responsibility of
individual patch writers going forward.

that have to conform to a specific interface, but don't necessarily need
to use all of their parameters. Let's mark them to avoid complaints from
-Wunused-parameter.
This was done mostly via guess-and-check with the Windows build in
GitHub CI. I also confirmed that the win+VS build is similarly happy.

As with the files touched in the previous commit, win32/headless.c does
not include git-compat-util.h, so it doesn't have our UNUSED macro.
Unlike those ones, this is not third-party code, so it would not be a
big deal to modify it.
However, I'm not sure if including git-compat-util.h would create other
headaches (and I don't even have a machine to test this on; I'm relying
on Windows CI to compile it at all). Given how trivial the file is, and
that the unused parameters are not interesting (they are just
boilerplate for the wWinMain() function), we can just use the same trick
as the previous commit and disable the warnings via pragma.

We carry some vendored 3rd-party code in compat/ that does not build
cleanly with -Wunused-parameters. We could mark these with UNUSED, but
there are two reasons not to:
1. This is code imported from elsewhere, so we'd prefer to avoid
modifying it in an invasive way that could create conflicts if we
tried to pull in a new version.
2. These files don't include git-compat-util.h at all, so we'd need to
factor out (or repeat) our UNUSED macro.
In theory we could modify the build process to invoke the compiler with
the extra warning disabled for these files, but there are tricky corner
cases there (e.g., for NO_REGEX we cannot assume that the compiler
understands -Wno-unused-parameter as an option, so we'd have to use our
detect-compiler script).
Instead, let's rely on the gcc diagnostic #pragma. This is horribly
unportable, of course, but it should do what we want. Compilers which
don't understand this particular pragma should ignore it (per the
standard), and compilers which do care about "-Wunused-parameter" will
hopefully respect it, even if they are not gcc (e.g., clang does).

In some cases, a user may be generating a patch for an old commit which
now has an out-of-date author or other identity. For example, consider a
team member who contributes to an internal fork of an upstream project,
but leaves before this change is submitted upstream.
In this case, the team members company address may no longer be valid,
and will thus bounce when sending email.
This can be manually avoided by editing the generated patch files, or by
carefully using --suppress-<cc|to> options. This requires a lot of
manual intervention and is easy to forget.
Git has support for mapping old email addresses and names to a canonical
name and address via the .mailmap file (and its associated mailmap.file,
mailmap.blob, and log.mailmap options).
Teach git send-email to enable mailmap support for all addresses. This
ensures that addresses point to the canonical real name and email
address.
Add the sendemail.mailmap configuration option and its associated
--mailmap (and --use-mailmap for compatibility with git log) options.
For now, the default behavior is to disable the mailmap in order to
avoid any surprises or breaking any existing setups.
These options support per-identity configuration via the
sendemail.identity configuration blocks. This enables identity-specific
configuration in cases where users may not want to enable support.
In addition, support send-email specific mailmap data via
sendemail.mailmap.file, sendemail.mailmap.blob and their
identity-specific variants.
The intention of these options is to enable mapping addresses which are
no longer valid to a current project or team maintainer. Such mappings
may change the actual person being referred to, and may not make sense
in a traditional mailmap file which is intended for updating canonical
name and address for the same individual.

The git check-mailmap command reads the mailmap from either the default
.mailmap location and then from the mailmap.blob and mailmap.file
configurations.
A following change to git send-email will want to support new
configuration options based on the configured identity. The
identity-based configuration and options only make sense in the context
of git send-email.
Expose the read_mailmap_file and read_mailmap_blob functions from
mailmap.c. Teach git check-mailmap the --mailmap-file and
--mailmap-blob options which load the additional mailmap sources.

git check-mailmap splits each provided contact using split_ident_line.
This function requires that the contact either be of the form "Name
<user@host>" or of the form "<user@host>". In particular, if the mail
portion of the contact is not surrounded by angle brackets,
split_ident_line will reject it.
This results in git check-mailmap rejecting attempts to translate simple
email addresses:
$ git check-mailmap user@host
fatal: unable to parse contact: user@host
This limits the usability of check-mailmap as it requires placing angle
brackets around plain email addresses.
In particular, attempting to use git check-mailmap to support mapping
addresses in git send-email is not straight forward. The sanitization
and validation functions in git send-email strip angle brackets from
plain email addresses. It is not trivial to add brackets prior to
invoking git check-mailmap.
Instead, modify check_mailmap() to allow such strings as contacts. In
particular, treat any line which cannot be split by split_ident_line as
a simple email address.
No attempt is made to actually parse the address line, or validate that
it is actually an email address. Implementing such validation is not
trivial. Besides, we weren't validating the address between angle
brackets before anyways.

"git config --get-all foo.bar" shows all values for the foo.bar
variable, but does not give the variable name in each output entry.
Hence it is equivalent to "git config get --all foo.bar", without
"--show-names", in the more modern syntax.

It is expected that reloading the stack fails with concurrent writers,
e.g. because a table that we just wanted to read just got compacted.
In case we decided to reuse readers this will cause a segfault though
because we unconditionally release all new readers, including the reused
ones. As those are still referenced by the current stack, the result is
that we will eventually try to dereference those already-freed readers.
Fix this bug by incrementing the refcount of reused readers temporarily.

The code flow of how we swap in the reloaded stack contents is somewhat
convoluted because we switch back and forth between swapping in
different parts of the stack.
Reorder the code to simplify it. We now first close and unlink the old
tables which do not get reused before we update the stack to point to
the new stack.
