In d9c66f0b5b (range-diff: first rudimentary implementation,
2018-08-13), we introduced the argument handling of the `range-diff`
command, special-casing three different stanzas based on the argument
count.
The somewhat unorthodox order (first handling the case of 2 arguments,
then 3, then 1) was chosen for clarity: the natural argument number is 2
because that is how many revision ranges are used internally. The code
to handle three arguments is relatively trivial, so it was added next.
And finally, the code to ungarble a single symmetric range into two
separate ones was added, because it was the most complicated (the most
inelegant part being about interpreting empty sides of the symmetric
range as `HEAD`).
In preparation for allowing pathspecs in `git range-diff` invocations,
where we no longer have the luxury of using the number of arguments to
disambiguate between these three different ways to specify the commit
ranges, we need to order these cases by argument count, in descending
order.
This patch is best viewed with `--color-moved`.

The "git remote rm" command's option parsing is fairly primitive: it
insists on a single argument, which it treats as the remote name, and
displays a usage message otherwise.
This is OK, and maybe even convenient, as you could run:
git remote rm --foo
to drop a remote named "--foo". But it's also weirdly unlike most of the
rest of Git, which would complain that there is no option "--foo". The
right way to spell it by our conventions is:
git remote rm -- --foo
but this doesn't currently work.
So let's bring the command in line with the rest of Git (including its
sibling subcommands!) by feeding argv to parse_options(). We already
have an empty options array for the usage helper.
Note that we have to adjust the argc index down by one, as
parse_options() eats the program name from the start of the array.

Several of the git-maintenance subcommands don't take any options, so
they don't bother looking at argv at all. This means they'll silently
accept garbage, like:
$ git maintenance register --foo
[no output]
$ git maintenance stop bar
[no output]
Let's give them the basic boilerplate to detect and handle these cases:
$ git maintenance register --foo
error: unknown option `foo'
usage: git maintenance register
$ git maintenance stop bar
usage: git maintenance stop
We could reduce the number of lines of code here a bit with a shared
helper function. But it's worth building out the boilerplate, as it may
serve as the base for adding options later.
Note one complication: maintenance_start() calls directly into
maintenance_register(), so it now needs to pass a plausible argv (we
don't care, but parse_options() is expecting there to at least be an
argv[0] program name). This is an extra line of code, but it eliminates
the need for an explanatory comment.

Recent commits such as bf0a6b65fc (builtin/multi-pack-index.c: let
parse-options parse subcommands, 2022-08-19) converted a few functions
to match our usual argc/argv/prefix conventions, but the prefix argument
remains unused.
However, there is a good use for it: they should pass it to their own
parse_options() functions, where it may be used to adjust the value of
any filename options. In all but one of these functions, there's no
behavior change, since they don't use OPT_FILENAME. But this is an
actual fix for one option, which you can see by modifying the test suite
like so:
diff --git a/t/t5326-multi-pack-bitmaps.sh b/t/t5326-multi-pack-bitmaps.sh

I'd emphasize that this wasn't broken by bf0a6b65fc; it has been broken
all along, because the sub-function never got to see the prefix. It is
that commit which is actually enabling us to fix it (and which also
brought attention to the problem because it triggers -Wunused-parameter!)
The other functions changed here don't use OPT_FILENAME at all. In their
cases this isn't fixing anything visible, but it's following the usual
pattern and future-proofing them against somebody adding new options and
being surprised.
I didn't include a test for the one visible case above. We don't
generally test routine parse-options behavior for individual options.
The challenge here was finding the problem, and now that this has been
done, it's not likely to regress. Likewise, we could apply the patch
above to cover it "for free" but it makes reading the rest of the test
unnecessarily complicated.

This adds several tests of `merge-tree -z` extended conflict output
behavior to the testsuite, including some tests adapted from t6422.
These tests mark current behavior, not necessarily optimal behavior. In
particular, some path_msg() calls might want to include additional
paths.
These testcases also make something clear about the <Conflicted file>
info section of the output. That section consists of a sequence of
lines of the form
<mode> <object> <stage> <filename>
where <stage> is always greater than 0 (since each line comes from a
conflicted file). The lines correspond to conflicts that would be
placed in the index if we were doing a merge in a working tree. It is
perhaps natural to assume that for any given line, the <object> and
<filename> correspond to a single <revision>:<filename> pair from one of
the commits being merged (or from the merge base). This is true for
simple conflicts. However, these testcases make it clear that this is
not the case in general. For example, <object> may be the hash of a
three-way content merge of three different files (and with different
filenames).
The tests no longer pass under TEST_PASSES_SANITIZE_LEAK; it appears
that doing a directory rename with "git mv", among other possible

After our loop through the selected strategies, we compare best_strategy
to wt_strategy. This is fine, but the fact that the code setting
best_strategy sets it to use_strategies[i]->name requires a little bit
of extra checking to determine that at the time of setting, that's the
same as wt_strategy. Just setting best_strategy to wt_strategy makes it
a little easier to verify what the loop is doing, at least for this
reader.
Further, use_strategies[i]->name is used in a number of places, where we
could just use wt_strategy. The latter takes less time for this reader
to parse (one variable name instead of three), so just use wt_strategy
to make the code slightly faster for human readers to parse.

builtin/merge.c has a loop over the specified strategies, where if they
all fail with conflicts, it picks the one with the least number of
conflicts.
In the codepath that finds a successful merge, if an automatic commit
was wanted, the code breaks out of the above loop, which makes sense.
However, if the user requested there be no automatic commit, the loop
would continue. That seems weird; --no-commit should not affect the
choice of merge strategy, but the code as written makes one think it
does. However, since the loop itself embeds "!merge_was_ok" as a
condition on continuing to loop, it actually would also exit early if
--no-commit was specified, it just exited from a different location.
Restructure the code slightly to make it clear that the loop will
immediately exit whenever we find a merge strategy that is successful.

The last commit changes the behavior of midx.c's `get_sorted_objects()`
function to handle the case of writing a MIDX bitmap while reusing an
existing MIDX and changing the identity of the preferred pack
separately.
As part of this change, all objects from the (new) preferred pack are
added to the fanout table in a separate pass. Since these copies of the
objects all have their preferred bits set, any duplicates will be
resolved in their favor.
Importantly, this includes any copies of those same objects that come
from the existing MIDX. We know at the time of adding them that they'll
be redundant if their source pack is the (new) preferred one, so we can
avoid adding them to the list in this case.

This patch resolves an issue where the object order used to generate a
MIDX bitmap would violate an invariant that all of the preferred pack's
objects are represented by that pack in the MIDX.
The problem arises when reusing an existing MIDX while generating a new
one, and occurs specifically when the identity of the preferred pack
changes from one MIDX to another, along with a few other conditions:
- the new preferred pack must also be present in the existing MIDX
- the new preferred pack must *not* have been the preferred pack in
the existing MIDX
- most importantly, there must be at least one object present in the
physical preferred pack (ie., it shows up in that pack's index)
but was selected from a *different* pack when the previous MIDX
was generated
When the above conditions are all met, we end up (incorrectly)
discarding copies of some objects in the pack selected as the preferred
pack. This is because `get_sorted_entries()` adds objects to its list
by doing the following at each fanout level:
- first, adding all objects from that fanout level from an existing
MIDX
- then, adding all objects from that fanout level in each pack *not*
included in the existing MIDX
So if some object was not selected from the to-be-preferred pack when
writing the previous MIDX, then we will never consider it as a candidate
when generating the new MIDX. This means that it's possible for the
preferred pack to not include all of its objects in the MIDX's
pseudo-pack object order, which is an invariant violation of that order.
Resolve this by adding all objects from the preferred pack separately
when it appears in the existing MIDX (if one was present). This will
duplicate objects from that pack that *did* appear in the MIDX, but this
is fine, since get_sorted_entries() already handles duplicates. (A
future optimization in this area could avoid adding copies of objects
that we know already existing in the MIDX.)
Note that we no longer need to compute the preferred-ness of objects
added from the MIDX, since we only want to select the preferred objects
from a single source. (We could still mark these preferred bits, but
doing so is redundant and unnecessary).
This resolves the bug demonstrated by t5326.174 ("preferred pack change
with existing MIDX bitmap").

Extract a routine to add all objects whose object ID's first byte is

pack_info` array maintained by the MIDX writing routine).
Unlike the previous extraction (for `midx_fanout_add_midx_fanout()`),
this function will be called twice, once for all new packs, and again
for the preferred pack (if it appears in an existing MIDX). The latter
change is to resolve the bug described a few patches ago, and will be
made in the subsequent commit.
Similar to the previous refactoring, this function also enhances the

To build up a list of objects (along with their packs, and the offsets
within those packs that each object appears at), the MIDX code
implements `get_sorted_entries()` which builds up a list of candidates,
sorts them, and then removes duplicate entries.
To do this, it keeps an array of `pack_midx_entry` structures that it
builds up once for each fanout level (ie., for all possible values of
the first byte of each object's ID).
This array is a function-local variable of `get_sorted_entries()`. Since
it uses the ALLOC_GROW() macro, having the `alloc_fanout` variable also
be local to that function, and only modified within that function is
convenient.
However, subsequent changes will extract the two ways this array is
filled (from a pack at some fanout value, and from an existing MIDX at
some fanout value) into separate functions. Instead of passing around
pointers to the entries array, along with `nr_fanout` and
`alloc_fanout`, encapsulate these three into a structure instead. Then
pass around a pointer to this structure instead.
This patch does not yet extract the above two functions, but sets us up
to begin doing so in the following commit. For now, the implementation
of get_sorted_entries() is only modified to replace `entries_by_fanout`
with `fanout.entries`, `nr_fanout` with `fanout.nr`, and so on.

The midx_bitmap_partial_tests() function is responsible for setting up a
state where some (but not all) packs in the repository are covered by a
MIDX (and bitmap).
This function has redirected the `git multi-pack-index write --bitmap`'s
stderr to a file "err" since its introduction back in c51f5a6437 (t5326:
test multi-pack bitmap behavior, 2021-08-31).
This was likely a stray change left over from a slightly different
version of this test, since the file "err" is never read after being
written. This leads to confusingly-missing output, especially when the
contents of stderr are important.

It is possible to generate a corrupt MIDX bitmap when certain conditions
are met. This happens when the preferred pack "P" changes to one (say,
"Q") that:
- "Q" has objects included in an existing MIDX,
- but "Q" is different than "P",
- and "Q" and "P" have some objects in common
When this is the case, not all objects from "Q" will be selected from
"Q" (ie., the generated MIDX will represent them as coming from a
different pack), despite "Q" being preferred.
This is an invariant violation, since all objects contained in the
MIDX's preferred pack are supposed to originate from the preferred pack.
In other words, all duplicate objects are resolved in favor of the copy
that comes from the MIDX's preferred pack, if any.
This violation results in a corrupt object order, which cannot be
interpreted by the pack-bitmap code, leading to broken clones and other
defects.
This test demonstrates the above problem by constructing a minimal
reproduction, and showing that the final `git clone` invocation fails.
The reproduction is mostly straightforward, except that the new pack
generated between MIDX writes (which is necessary in order to prevent
that operation from being a noop) must sort ahead of all existing packs
in order to prevent a different pack (neither "P" nor "Q") from
appearing as preferred (meaning all its objects appear in order at the
beginning of the pseudo-pack order).
Subsequent commits will first refactor the midx.c::get_sorted_entries()
function, and then fix this bug.

The entry point to the patience-diff algorithm takes two mmfile_t
structs with the original file contents, but it doesn't actually do
anything useful with them. This is similar to the case recently cleaned
up in the histogram code via f1d019071e (xdiff: drop unused mmfile
parameters from xdl_do_histogram_diff(), 2022-08-19), but there's a bit
more subtlety going on.
We pass them into the recursive patience_diff(), which in turn passes
them into fill_hashmap(), which stuffs the pointers into a struct. But
the only thing which reads the struct fields is our recursion into
patience_diff()!
So it's unlikely that something like -Wunused-parameter could find this
case: it would have to detect the circular dependency caused by the
recursion (not to mention tracing across struct field assignments).
But once found, it's easy to have the compiler confirm what's going on:
1. Drop the "file1" and "file2" fields from the hashmap struct
definition. Remove the assignments in fill_hashmap(), and
temporarily substitute NULL in the recursive call to
patience_diff(). Compiling shows that no other code touched those
fields.
2. Now fill_hashmap() will trigger -Wunused-parameter. Drop "file1"
and "file2" from its definition and callsite.
3. Now patience_diff() will trigger -Wunused-parameter. Drop them
there, too. One of the callsites is the recursion with our
NULL values, so those temporary values go away.
4. Now xdl_do_patience_diff() will trigger -Wunused-parameter. Drop
them there. And we're done.

Traditionally, reflog messages were never translated, in particular not
on storage.
Due to the switch of more parts of git to the sequencer, old changes in
the sequencer code may lead to recent changes in git's behaviour. E.g.:
c28cbc5ea6 ("sequencer: mark action_name() for translation", 2016-10-21)
marked several uses of `action_name()` for translation. Recently, this
lead to a partially translated reflog:
`rebase: fast-forward` is translated (e.g. in de to `Rebase: Vorspulen`)
whereas other reflog entries such as `rebase (pick):` remain
untranslated as they should be.
Change the relevant line in the sequencer so that this reflog entry
remains untranslated, as well.

This field has not been used since the function was introduced in
b559263216 (exclude: split pathname matching code into a separate
function, 2012-10-15), though there was a brief period where it was
erroneously used and then reverted in ed4958477b (dir: fix pattern
matching on dirs, 2021-09-24) and 5ceb663e92 (dir: fix
directory-matching bug, 2021-11-02).
It's possible we'd eventually add a flag that makes it useful here, but
there are only a handful of callers. It would be easy to add back if
necessary, and in the meantime this makes the function interface less
misleading.

This function has never used its "commit" parameter since it was added
in db757e8b8d (show, log: provide a --remerge-diff capability,
2022-02-02).
This makes sense; we already have separate parameters for the parents
(which lets us redo the merge) and the oid of the result tree (which we
can then diff against the remerge result).
Let's drop the unused parameter in the name of clarity.

These are no longer used since 9df0fc3d57 (xdiff: fix a memory leak,
2022-02-16), as the caller is expected to call xdl_prepare_env() itself.
After that change the histogram code only examines the prepared
xdfenv_t, not the original buffers.

In the non-Windows version of this function, we never have any errors to
report, and thus the "report" parameter is unused. But we can't drop it,
because we have to maintain function call compatibility with the version
in compat/mingw.h, which does use this parameter.
Note that there's an extra level of indirection here; the common
function is actually is_path_owned_by_current_user, which is a macro
pointing to "by_current_uid" or "by_current_sid", depending on the
platform. So an alternative here is to eat the unused parameter in the
macro, since -Wunused-parameter doesn't complain about macros. But I
think the UNUSED() annotation is less obfuscated for somebody reading
the code later.

The start_async(), etc, functions need a "proc" callback that conforms
to a particular interface. Not every callback needs every parameter
(e.g., the caller might not even ask to open an input descriptor, in
which case there is no point in the callback looking at it). Let's mark
these for -Wunused-parameter.

Hashmap comparison functions must conform to a particular callback
interface, but many don't use all of their parameters. Especially the
void cmp_data pointer, but some do not use keydata either (because they
can easily form a full struct to pass when doing lookups). Let's mark
these to make -Wunused-parameter happy.

The callback passed to git_config() must conform to a particular
interface. But most callbacks don't actually look at the extra "void
*data" parameter. Let's mark the unused parameters to make
-Wunused-parameter happy.
Note there's one unusual case here in get_remote_default() where we
actually ignore the "value" parameter. That's because it's only checking
whether the option is found at all, and not parsing its value.
