When advancing the merged iterator, we pop the topmost entry from its
priority queue and then advance the sub-iterator that the entry belongs
to, adding the result as a new entry. This is quite sensible in the case
where the merged iterator is used to actually iterate through records.
But the merged iterator is also used when we look up a single record,
only, so advancing the sub-iterator is wasted effort because we would
never even look at the result.
Instead of immediately advancing the sub-iterator, we can also defer
this to the next iteration of the merged iterator by storing the
intent-to-advance. This results in a small speedup when reading many
records. The following benchmark creates 10000 refs, which will also end
up with many ref lookups:
Benchmark 1: update-ref: create many refs (revision = HEAD~)
Time (mean ± σ): 337.2 ms ± 7.3 ms [User: 200.1 ms, System: 136.9 ms]
Range (min … max): 329.3 ms … 373.2 ms 100 runs
Benchmark 2: update-ref: create many refs (revision = HEAD)
Time (mean ± σ): 332.5 ms ± 5.9 ms [User: 197.2 ms, System: 135.1 ms]
Range (min … max): 327.6 ms … 359.8 ms 100 runs
Summary
update-ref: create many refs (revision = HEAD) ran
1.01 ± 0.03 times faster than update-ref: create many refs (revision = HEAD~)
While this speedup alone isn't really worth it, this refactoring will
also allow two additional optimizations in subsequent patches. First, it
will allow us to special-case when there is only a single sub-iter left
to circumvent the priority queue altogether. And second, it makes it
easier to avoid copying records to the caller.

The reftable priority queue is used by the merged iterator to yield
records from its sub-iterators in the expected order. Each entry has a
record corresponding to such a sub-iterator as well as an index that
indicates which sub-iterator the record belongs to. But while the
sub-iterators are tracked with a `size_t`, we store the index as an
`int` in the entry.
Fix this and use `size_t` consistently.

The TODO comment suggested to heed core.bare from template config file
if no command line override given. And the prev_bare_repository
variable seems to have been placed for this sole purpose as it is not
used anywhere else.
However, it was clarified by Junio [1] that such values (including
core.bare) are ignored intentionally and does not make sense to
propagate them from template config to repository config. Also, the
directories for the worktree and repository are already created, and
therefore the bare/non-bare decision has already been made, by the
point we reach the codepath where the TODO comment is placed.
Therefore, prev_bare_repository does not have a usecase with/without
supporting core.bare from template. And the removal of
prev_bare_repository is safe as proved by the later part of the
comment:
"Unfortunately, the line above is equivalent to
is_bare_repository_cfg = !work_tree;
which ignores the config entirely even if no `--[no-]bare`
command line option was present.
To see why, note that before this function, there was this call:
prev_bare_repository = is_bare_repository()
expanding the right hand side:
= is_bare_repository_cfg && !get_git_work_tree()
= is_bare_repository_cfg && !work_tree
note that the last simplification above is valid because nothing
calls repo_init() or set_git_work_tree() between any of the
relevant calls in the code, and thus the !get_git_work_tree()
calls will return the same result each time. So, what we are
interested in computing is the right hand side of the line of
code just above this comment:
prev_bare_repository || !work_tree
= is_bare_repository_cfg && !work_tree || !work_tree
= !work_tree
because "A && !B || !B == !B" for all boolean values of A & B."
Therefore, remove the TODO comment and remove prev_bare_repository
variable. Also, update relevant testcases and remove one redundant
testcase.

When no subcommand is specified to "reflog", we assume "show" [1]:
$ git reflog -h
usage: git reflog [show] [<log-options>] [<ref>]
...
This implicit "show" is not being completed correctly:
$ git checkout -b default
$ git reflog def<TAB><TAB>
... no completion options ...
The expected result is:
$ git reflog default
This happens because we're completing references after seeing a valid
subcommand in the command line. This prevents the implicit "show" from
working properly, but also introduces a new problem: it keeps offering
subcommand options when the subcommand is implicit:
$ git checkout -b explore
$ git reflog default ex<TAB>
...
$ git reflog default expire
The expected result is:
$ git reflog default explore
To fix this, complete references even if no subcommand is present, or in
other words when the subcommand is implicit "show".
Also, only include completion options for subcommands when completing
the right position in the command line.

What -n actually does in addition to its documented behavior is
ignoring of configuration variable clean.requireForce, that makes
sense provided -n prevents files removal anyway.
So, first, document this in the manual, and then modify implementation
to make this more explicit in the code.
Improved implementation also stops to share single internal variable
'force' between command-line -f option and configuration variable
clean.requireForce, resulting in more clear logic.
Two error messages with slightly different text depending on if
clean.requireForce was explicitly set or not, are merged into a single

The resulting error message now does not mention -n as well, as it
neither matches intended clean.requireForce usage nor reflects

Git currently does not detect the ambiguity of an option that starts
with "no" like --notes and its negated form if given just --n or --no.
All Git commands with such options have other negatable options, and
we detect the ambiguity with them, so that's currently only a potential
problem for scripts that use git rev-parse --parseopt.
Let's fix it nevertheless, as there's no need for that confusion. To
detect the ambiguity we have to loosen the check in register_abbrev(),
as an option is considered an alias of itself. Add non-matching
negation flags as a criterion to recognize an option being ambiguous
with its negated form.

abbreviated candidate and perform the negation checks in the same

Giving an argument to an option that doesn't take one causes Git to
report that error specifically:

error: option `dry-run' takes no value
The same is true when the option is negated or abbreviated:
$ git rm --no-dry-run=bogus
error: option `no-dry-run' takes no value
$ git rm --dry=bogus
error: option `dry-run' takes no value
Not so when doing both, though:
$ git rm --no-dry=bogus
error: unknown option `no-dry=bogus'
usage: git rm [-f | --force] [-n] [-r] [--cached] [--ignore-unmatch]
(Rest of the usage message omitted.)

This is another preparatory refactor to unify the trailer formatters.
For background, note that the "trailers" string array is the
`char **trailers` member in `struct trailer_info` and that the
trailer_item objects are the elements of the `struct list_head *head`
linked list.
Currently trailer_info_get() only populates `char **trailers`. And
parse_trailers() first calls trailer_info_get() so that it can use the
`char **trailers` to populate a list of `struct trailer_item` objects
Instead of calling trailer_info_get() directly from
format_trailers_from_commit(), make it call parse_trailers() instead
because parse_trailers() already calls trailer_info_get().
This change is a NOP because format_trailer_info() (which
format_trailers_from_commit() wraps around) only looks at the "trailers"
string array, not the trailer_item objects which parse_trailers()
populates. For now we do need to create a dummy
LIST_HEAD(trailer_objects);
because parse_trailers() expects it in its signature.
In a future patch, we'll change format_trailer_info() to use the parsed
trailer_item objects (trailer_objects) instead of the `char **trailers`
array.

One might intuitively think that format_trailers_from_commit() builds on

format_trailers_from_commit() calls format_trailer_info() and
format_trailers() is never called in that codepath.

The shortlog builtin was taught to use the trailer iterator interface in

The iterator always unfolds values and this has always been the case
since the time the iterator was first introduced in f0939a0eb1 (trailer:
add interface for iterating over commit trailers, 2020-09-27). Add a
comment line to remind readers of this behavior.
The fact that the iterator always unfolds values is important
(at least for shortlog) because unfolding allows it to recognize both
folded and unfolded versions of the same trailer for de-duplication.
Capture the existing behavior in a new test case to guard against
regressions in this area. This test case is based off of the existing
"shortlog de-duplicates trailers in a single commit" just above it. Now
if we were to remove the call to
unfold_value(&iter->val);

not used in special ways, change the type of 'flags' to unsigned.

Clients are only supposed to request particular capabilities or features
if the server advertised them. For the "packfile-uris" feature, we only
advertise it if uploadpack.blobpacfileuri is set, but we always accept a
request from the client regardless.
In practice this doesn't really hurt anything, as we'd pass the client's
protocol list on to pack-objects, which ends up ignoring it. But we
should try to follow the protocol spec, and tightening this up may catch
buggy or misbehaving clients more easily.
Thanks to recent refactoring, we can hoist the config check from
upload_pack_advertise() into upload_pack_config(). Note the subtle
handling of a value-less bool (which does not count for triggering an
advertisement).

(Actually, this commit is only about passing on "missing commits"
errors, but adding that to the commit's title would have made it too
long.)
The `merge_bases_many()` function was just taught to indicate parsing
errors, and now the `repo_get_merge_bases_many_dirty()` function is
aware of that, too.
