write_buffer() reports the OS error if it is unable to write. Its only
caller dies in that case, giving some more context in its last message.
Inline this function and show only a single error message that includes
both the context (writing a loose object file) and the OS error. This
shortens the code and simplifies the output.

Since f12fa9ee6c (userdiff: add and use for_each_userdiff_driver(),
2021-04-08), lookup of userdiffs is done with a generic
for_each_userdiff_driver(). But the name lookup doesn't use the "type"
field, of course.
We can't get rid of that field from the generic interface because it is
used by t/helper/test-userdiff.c. So mark it as unused in this instance
to silence -Wunused-parameter.

The diff code provides a format_callback interface, but not every
callback needs each parameter (e.g., the "opt" and "data" parameters are
frequently left unused). Likewise for the output_prefix callback, the
low-level change/add_remove interfaces, the callbacks used by
xdi_diff(), etc.

The def_ff() function is the default "find_func" for finding hunk
headers. It has never used its "priv" argument since it was introduced
in f258475a6e (Per-path attribute based hunk header selection.,
2007-07-06). But back then we used a function pointer to switch between
a caller-provided function and the default, so the two had to conform to
the same interface.
In ff2981f724 (xdiff: factor out match_func_rec(), 2016-05-28), that
pointer indirection went away in favor of code which directly calls
either of the two functions. So there's no need for def_ff() to retain
this unused parameter.

We take a ws_rule parameter, but have never looked at it since the
function was added in 877f23ccb8 (Teach "diff --check" about new blank
lines at end, 2008-06-26). A comment in the function does mention how we
_could_ use it, but nobody has felt the need to do so for over a decade.
We could keep it around as reminder of what could be done, but the
comment serves that purpose. And in the meantime, it triggers
-Wunused-parameter.
So let's drop it, which in turn allows us to drop similar arguments
further up the callstack. I've left the comment intact. It does still
say "ws_rule", but that name is used consistently in the whitespace
code, so the meaning is clear.

Our object graph traversal code has a process_gitlink() function which
we call when we see a gitlink entry. The function does nothing; it was
added in the early days of gitlinks by 6e2f441bd4 (Teach git
list-objects logic to not follow gitlinks, 2007-04-13).
The comment above the function talks about some things we _could_ do.
But in the intervening 15 years, nobody has touched the function, and
the submodule code usually makes its own decisions about when and how to
examine the links. At the generic traversal layer, we can't assume that
the pointed-to commit is available.
Let's drop this placeholder that isn't really helping anything. This
silences some -Wunused-parameter warnings, and also gets rid of a crufty
use of "const unsigned char *" to pass a raw hash value.

Our parse_blob_buffer() takes a ptr/len combo, just like
parse_tree_buffer(), etc, and returns success or failure. But it doesn't
actually do anything with them; we just set the "parsed" flag in the
object and return success, without even looking at the contents.
There could be some value to keeping these unused parameters:
- it's consistent with the parse functions for other object types. But
we already lost that consistency in 837d395a5c (Replace parse_blob()
with an explanatory comment, 2010-01-18).
- As the comment from 837d395a5c explains, callers are supposed to
make sure they have the object content available. So in theory
asking for these parameters could serve as a signal. But there are
only two callers, and one of them always passes NULL (after doing a
streaming check of the object hash).
This shows that there aren't likely to be a lot of callers (since
everyone either uses the type-generic parse functions, or handles
blobs individually), and that they need to take special care anyway
(because we usually want to avoid loading whole blobs in memory if
we can avoid it).
So let's just drop these unused parameters, and likewise the useless
return value. While we're touching the header file, let's move the
declaration of parse_blob_buffer() right below that explanatory comment,
where it's more likely to be seen by people looking for the function.

The ls_refs() function (for the v2 protocol command of the same name)
takes a repository parameter (like all v2 commands), but ignores it. It
should use it to access the refs.
This isn't a bug in practice, since we only call this function when
serving upload-pack from the main repository. But it's an awkward
gotcha, and it causes -Wunused-parameter to complain.
The main reason we don't use the repository parameter is that the ref
iteration interface we call doesn't have a "refs_" variant that takes a
ref_store. However we can easily add one. In fact, since there is only
one other caller (in ref-filter.c), there is no need to maintain the
non-repository wrapper; that caller can just use the_repository. It's
still a long way from consistently using a repository object, but it's
one small step in the right direction.

The server_supports_v2() helper lets a caller find out if the server
supports a feature, and will optionally die if it's not supported. This
makes the return value confusing, as it's only meaningful when the
function is not asked to die.
Coverity flagged a new call like:
/* check that we support "foo" */
server_supports_v2("foo", 1);
complaining that we usually checked the return value, but this time we
didn't. But this call is correct, and other ones that did:
if (server_supports_v2("foo", 1))
do_something_with_foo();
are "wrong", in the sense that we know the conditional will always be
true (but there's no bug; the code is simply misleading).
Let's split the "die" behavior into its own function which returns void,
and modify each caller to use the correct one.

apply_parse_options() passes the array of argument strings to
parse_options(), which removes recognized options. The removed strings
are not freed, though.
Make a copy of the strvec to pass to the function to retain the pointers

Don't put clean parents on the pending list, as they and their ancestors

reflog_expiry_prepare() calls mark_reachable(), which recurively flags
commits as REACHABLE. The traversal stops beyond a certain age
threshold; the boundary commits also marked as REACHABLE and put back
into mark_list at the end. unreachable() finishes the traversal down to
the roots if necessary -- but if all interesting commits are younger
than the age threshold then only recent commits need to be visited.
When this optimization works then the boundary commits still sit there
in mark_list at the end. Clear their REACHABLE flag and release the
commit list allocations.
While at it remove a duplicate code line from mark_reachable(); the same
flag is already set five lines up.

ee4512ed48 ("trace2: create new combined trace facility", 2019-02-
22) introduced trace2_cmd_name() and taught both the Git built-ins and
some non-built-ins to use it. However, http-fetch was not one of them
(perhaps due to its low usage at the time).
Teach http-fetch to invoke this function. After this patch, this
function will be invoked right after argument parsing, just like in
remote-curl.c.

Currently, auto correction doesn't work reliably for commands which must
run in a work tree (e.g. `git status`) in Git work trees which are
created from a bare repository.
As far as I'm able to determine, this has been broken since commit
659fef199f (help: use early config when autocorrecting aliases,
2017-06-14), where the call to `git_config()` in `help_unknown_cmd()`
was replaced with a call to `read_early_config()`. From what I can tell,
the actual cause for the unexpected error is that we call
`git_default_config()` in the `git_unknown_cmd_config` callback instead
of simply returning `0` for config entries which we aren't interested
in.
Calling `git_default_config()` in this callback to `read_early_config()`
seems like a bad idea since those calls will initialize a bunch of state
in `environment.c` (among other things `is_bare_repository_cfg`) before
we've properly detected that we're running in a work tree.
All other callbacks provided to `read_early_config()` appear to only
extract their configurations while simply returning `0` for all other
config keys.
This commit changes the `git_unknown_cmd_config` callback to not call
`git_default_config()`. Instead we also simply return `0` for config
keys which we're not interested in.
Additionally the commit adds a new test case covering `help.autocorrect`
in a work tree created from a bare clone.

When Git's test suite uses `test_cmp`, it is not actually trying to
compare binary files as the name `cmp` would suggest to users familiar
with Unix' tools, but the tests instead verify that actual output
matches the expected text.
On Unix, `cmp` works well enough for Git's purposes because only Line
Feed characters are used as line endings. However, on Windows, while
most tools accept Line Feeds as line endings, many tools produce
Carriage Return + Line Feed line endings, including some of the tools
used by the test suite (which are therefore provided via Git for Windows
SDK). Therefore, `cmp` would frequently fail merely due to different
line endings.
To accommodate for that, the `mingw_test_cmp` function was introduced
into Git's test suite to perform a line-by-line comparison that ignores
line endings. This function is a Bash function that is only used on
Windows, everywhere else `cmp` is used.
This is a double whammy because `cmp` is fast, and `mingw_test_cmp` is
slow, even more so on Windows because it is a Bash script function, and
Bash scripts are known to run particularly slowly on Windows due to
Bash's need for the POSIX emulation layer provided by the MSYS2 runtime.
The commit message of 32ed3314c104 (t5351: avoid using `test_cmp` for
binary data, 2022-07-29) provides an illuminating account of the
consequences: On Windows, the platform on which Git could really use all
the help it can get to improve its performance, the time spent on one
entire test script was reduced from half an hour to less than half a
minute merely by avoiding a single call to `mingw_test_cmp` in but a
single test case.
Learning the lesson to avoid shell scripting wherever possible, the Git
for Windows project implemented a minimal replacement for
`mingw_test_cmp` in the form of a `test-tool` subcommand that parses the
input files line by line, ignoring line endings, and compares them.
Essentially the same thing as `mingw_test_cmp`, but implemented in
C instead of Bash. This solution served the Git for Windows project
well, over years.
However, when this solution was finally upstreamed, the conclusion was
reached that a change to use `git diff --no-index` instead of
`mingw_test_cmp` was more easily reviewed and hence should be used
instead.
The reason why this approach was not even considered in Git for Windows
is that in 2007, there was already a motion on the table to use Git's
own diff machinery to perform comparisons in Git's test suite, but it
was dismissed in https://lore.kernel.org/git/xmqqbkrpo9or.fsf@gitster.g/
as undesirable because tests might potentially succeed due to bugs in
the diff machinery when they should not succeed, and those bugs could
therefore hide regressions that the tests try to prevent.
By the time Git for Windows' `mingw-test-cmp` in C was finally
contributed to the Git mailing list, reviewers agreed that the diff
machinery had matured enough and should be used instead.
When the concern was raised that the diff machinery, due to its
complexity, would perform substantially worse than the test helper
originally implemented in the Git for Windows project, a test
demonstrated that these performance differences are well lost within the
100+ minutes it takes to run Git's test suite on Windows.

The old version we currently use runs in node.js v12.x, which is being
deprecated in GitHub Actions. The new version uses node.js v16.x.
Incidentally, this also avoids the warning about the deprecated
`::set-output::` workflow command because the newer version of the
`github-script` Action uses the recommended new way to specify outputs.
