It has been a frequent matter of contention that the win+VS jobs not
only take a long time to run, but are also more easily broken than the
other jobs (because they do not use the same `Makefile`-based builds as
all other jobs), and to make matters worse, these breakages are also
much harder to diagnose and fix than other jobs', especially for
contributors who are happy to stay away from Windows.
The purpose of these win+VS jobs is to maintain the CMake-based build
of Git, with the target audience being Visual Studio users on Windows
who are typically quite unfamiliar with `make` and POSIX shell
scripting, but the benefit of whose expertise we want for the Git
project nevertheless.
The CMake support was introduced for that specific purpose, and already
early on concerns were raised that it would put an undue burden on
contributors to ensure that these jobs pass in CI, when they do not have
access to Windows machines (nor want to have that).
This developer's initial hope was that it would be enough to fix win+VS
failures and provide the changes to be squashed into contributors'
patches, and that it would be worth the benefit of attracting
Windows-based developers' contributions.
Neither of these hopes have panned out.
To lower the frustration, and incidentally benefit from using way less
build minutes, let's just not run the win+VS jobs by default, which
appears to be the consensus of the mail thread leading up to
https://lore.kernel.org/git/xmqqk0311blt.fsf@gitster.g/
Since the Git for Windows project still needs to at least try to attract
more of said Windows-based developers, let's keep the jobs, but disable
them everywhere except in Git for Windows' fork. This will help because
Git for Windows' branch thicket is "continuously rebased" via automation
to the `shears/maint`, `shears/main`, `shears/next` and `shears/seen`
branches at https://github.com/git-for-windows/git. That way, the Git
for Windows project will still be notified early on about potential
breakages, but the Git project won't be burdened with fixing them
anymore, which seems to be the best compromise we can get on this issue.

When the -L argument to "git log" is passed the zero-width regular
expression "$" (as in "-L :$:line-range.c"), this results in an
infinite loop in find_funcname_matching_regexp().
Modify find_funcname_matching_regexp to correctly match the entire line
instead of the zero-width match at eol and update the loop condition to
prevent an infinite loop in the event of other undiscovered corner cases.
The primary change is that we pre-decrement the beginning-of-line marker
('bol') before comparing it to '\n'. In the case of '$', where we match the
'\n' at the end of the line and start the loop with bol == eol, this
ensures that bol will find the beginning of the line on which the match
occurred.

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

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 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.

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.
