When the sha1collisiondetection library was added and made the default
in [1] the interaction with APPLE_COMMON_CRYPTO added in [2] and [3]
seems to have been missed. On modern OSX and Darwin we are able to use
Apple's CommonCrypto both for SHA-1, and as a generic (but partial)
OpenSSL replacement.
This left OSX and Darwin without protection against the SHAttered
attack when building Git in its default configuration.
Let's also use sha1collisiondetection on OSX, to do so we'll need to
split up the "APPLE_COMMON_CRYPTO" flag into that flag and a new
"APPLE_COMMON_CRYPTO_SHA1".
Because of this we can stop conflating whether we want to use Apple's
CommonCrypto at all, and whether we want to use it for SHA-1. This
makes the CI recipe added in [4] simpler.

The error message for a bogus argument to %(authoremail), etc, is:
$ git for-each-ref --format='%(authoremail:foo)'
fatal: unrecognized email option: foo
Saying just "email" is a little vague; most of the other atom parsers
would use the full name "%(authoremail)", but we can't do that here
because the same function also handles %(taggeremail), etc. Until
recently, passing atom->name was a bad idea, because it erroneously
included the arguments in the atom name. But since the previous commit
taught err_bad_arg() to handle this, we can now do so and get:
fatal: unrecognized %(authoremail) argument: foo
which is consistent with other atoms.

If you pass a bogus argument to %(refname), you may end up with a
message like this:
$ git for-each-ref --format='%(refname:foo)'
fatal: unrecognized %(refname:foo) argument: foo
which is confusing. It should just say:
fatal: unrecognized %(refname) argument: foo
which is clearer, and is consistent with most other atom parsers. Those
other parsers do not have the same problem because they pass the atom
name from a string literal in the parser function. But because the
parser for %(refname) also handles %(upstream) and %(push), it instead
uses atom->name, which includes the arguments. The oid atom parser which
handles %(tree), %(parent), etc suffers from the same problem.
It seems like the cleanest fix would be for atom->name to be _just_ the
name, since there's already a separate "args" field. But since that
field is also used for other things, we can't change it easily (e.g.,
it's how we find things in the used_atoms array, and clearly %(refname)
and %(refname:short) are not the same thing).
Instead, we'll teach our error_bad_arg() function to stop at the first
":". This is a little hacky, as we're effectively re-parsing the name,
but the format is simple enough to do this as a one-liner, and this
localizes the change to the error-reporting code.
We'll give the same treatment to err_no_arg(). None of its callers use
this atom->name trick, but it's worth future-proofing it while we're
here.

Atom parsers that take arguments generally have a catch-all for "this
arg is not recognized". Most of them use the same printf template, which
is good, because it makes life easier for translators. Let's pull this

shorter and avoids any possibility of differences.

Many atom parsers give the same error message, differing only in the
name of the atom. If we use "%s does not take arguments", that should
make life easier for translators, as they only need to translate one
string. And in doing so, we can easily pull it into a helper function to
make sure they are all using the exact same string.
I've added a basic test here for %(HEAD), just to make sure this code is
exercised at all in the test suite. We could cover each such atom, but

Replace the call to `FSEventStreamScheduleWithRunLoop()` function with
the suggested `FSEventStreamSetDispatchQueue()` function.
The MacOS version of the builtin FSMonitor feature uses the
`FSEventStreamScheduleWithRunLoop()` function to drive the event loop
and process FSEvents from the system. This routine has now been
deprecated by Apple. The MacOS 13 (Ventura) compiler tool chain now
generates a warning when compiling calls to this function. In
DEVELOPER=1 mode, this now causes a compile error.
The `FSEventStreamSetDispatchQueue()` function is conceptually similar
and is the suggested replacement. However, there are some subtle
thread-related differences.
Previously, the event stream would be processed by the
`fsm_listen__loop()` thread while it was in the `CFRunLoopRun()`
method. (Conceptually, this was a blocking call on the lifetime of
the event stream where our thread drove the event loop and individual
events were handled by the `fsevent_callback()`.)
With the change, a "dispatch queue" is created and FSEvents will be
processed by a hidden queue-related thread (that calls the
`fsevent_callback()` on our behalf). Our `fsm_listen__loop()` thread
maintains the original blocking model by waiting on a mutex/condition
variable pair while the hidden thread does all of the work.
While the deprecated API used by the original were introduced in
macOS 10.5 (Oct 2007), the API used by the updated code were
introduced back in macOS 10.6 (Aug 2009) and has been available
since then. So this change _could_ break those who have happily
been using 10.5 (if there were such people), but these two dates
both predate the oldest versions of macOS Apple seems to support
anyway, so we should be safe.

In ff2981f724 (xdiff: factor out match_func_rec(), 2016-05-28), that

examine the links. At the generic traversal layer, we can't assume that

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.

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.
