The `refs_create_symref()` function is used to update/create a symref.
But it doesn't check the old target of the symref, if existing. It force
updates the symref. In this regard, the name `refs_create_symref()` is a
bit misleading. So let's rename it to `refs_update_symref()`. This is
akin to how 'git-update-ref(1)' also allows us to create apart from
update.
While we're here, rename the arguments in the function to clarify what
they actually signify and reduce confusion.

The function `ref_transaction_update()` obtains ref information and
flags to create a `ref_update` and add them to the transaction at hand.
To extend symref support in transactions, we need to also accept the
old and new ref targets and process it. This commit adds the required
parameters to the function and modifies all call sites.
The two parameters added are `new_target` and `old_target`. The
`new_target` is used to denote what the reference should point to when
the transaction is applied. Some functions allow this parameter to be
NULL, meaning that the reference is not changed.
The `old_target` denotes the value the reference must have before the
update. Some functions allow this parameter to be NULL, meaning that the
old value of the reference is not checked.
We also update the internal function `ref_transaction_add_update()`
similarly to take the two new parameters.

It is possible to run git-shortlog(1) outside of a repository by passing
it output from git-log(1) via standard input. Obviously, as there is no
repository in that context, it is thus unsupported to pass any revisions
as arguments.
Regardless of that we still end up calling `setup_revisions()`. While
that works alright, it is somewhat strange. Furthermore, this is about
to cause problems when we unset the default object hash.
Refactor the code to only call `setup_revisions()` when we have a
repository. This is safe to do as we already verify that there are no
arguments when running outside of a repository anyway.

The git-diff(1) command can be used outside repositories to diff two
files with each other. But even if there is no repository we will end up
hashing the files that we are diffing so that we can print the "index"
line:
```
diff --git a/a b/b
index 7898192..6178079 100644
--- a/a
+++ b/b
@@ -1 +1 @@
-a
+b
```
We implicitly use SHA1 to calculate the hash here, which is because
`the_repository` gets initialized with SHA1 during the startup routine.
We are about to stop doing this though such that `the_repository` only
ever has a hash function when it was properly initialized via a repo's
configuration.
To give full control to our users, we would ideally add a new switch to
git-diff(1) that allows them to specify the hash function when executed
outside of a repository. But for now, we only convert the code to make
this explicit such that we can stop setting the default hash algorithm
for `the_repository`.

Verifying a bundle requires us to have a repository. This is encoded in
`verify_bundle()`, which will return an error if there is no repository.
We call `open_bundle()` before we call `verify_bundle()` though, which
already performs some verifications even though we may ultimately abort
due to a missing repository.
This is problematic because `open_bundle()` already reads the bundle
header and verifies that it contains a properly formatted hash. When
there is no repository we have no clue what hash function to expect
though, so we always end up assuming SHA1 here, which may or may not be
correct. Furthermore, we are about to stop initializing `the_hash_algo`
when there is no repository, which will lead to segfaults.
Check early on whether we have a repository to fix this issue.

We access `the_hash_algo` in git-blame(1) before we have executed
`parse_options_start()`, which may not be properly set up in case we
have no repository. This is fine for most of the part because all the
call paths that lead to it (git-blame(1), git-annotate(1) as well as
git-pick-axe(1)) specify `RUN_SETUP` and thus require a repository.
There is one exception though, namely when passing `-h` to print the
help. Here we will access `the_hash_algo` even if there is no repo.
This works fine right now because `the_hash_algo` gets sets up to point
to the SHA1 algorithm via `initialize_repository()`. But we're about to
stop doing this, and thus the code would lead to a `NULL` pointer
exception.
Prepare the code for this and only access `the_hash_algo` after we are
sure that there is a proper repository.

The `--short=` option for git-rev-parse(1) allows the user to specify
to how many characters object IDs should be shortened to. The option is
broken though for SHA256 repositories because we set the maximum allowed
hash size to `the_hash_algo->hexsz` before we have even set up the repo.
Consequently, `the_hash_algo` will always be SHA1 and thus we truncate
every hash after at most 40 characters.
Fix this by accessing `the_hash_algo` only after we have set up the
repo.

We see too often that a range-diff added to format-patch output
shows too many "unmatched" patches. This is because the default
value for creation-factor is set to a relatively low value.
It may be justified for other uses (like you have a yet-to-be-sent
new iteration of your series, and compare it against the 'seen'
branch that has an older iteration, probably with the '--left-only'
option, to pick out only your patches while ignoring the others) of
"range-diff" command, but when the command is run as part of the
format-patch, the user _knows_ and expects that the patches in the
old and the new iterations roughly correspond to each other, so we
can and should use a much higher default.

Until now, `git config -h` would have printed help for the old-style
syntax. Now that all modes have proper subcommands though it is
preferable to instead display the subcommand help.
Drop the `NO_INTERNAL_HELP` flag to do so. While at it, drop the help
mismatch in t0450 and add the `--get-colorbool` option to the usage such
that git-config(1)'s synopsis and `git config -h` match.

While git-config(1) has several modes, those modes are not exposed with
subcommands but instead by specifying action flags like `--unset` or
`--list`. This user interface is not really in line with how our more
modern commands work, where it is a lot more customary to say e.g. `git
remote list`. Furthermore, to add to the confusion, git-config(1) also
allows the user to request modes implicitly by just specifying the
correct number of arguments. Thus, `git config foo.bar` will retrieve
the value of "foo.bar" while `git config foo.bar baz` will set it to
"baz".
Overall, this makes for a confusing interface that could really use a
makeover. It hurts discoverability of what you can do with git-config(1)
and is comparatively easy to get wrong. Converting the command to have
subcommands instead would go a long way to help address these issues.
One concern in this context is backwards compatibility. Luckily, we can
introduce subcommands without breaking backwards compatibility at all.
This is because all the implicit modes of git-config(1) require that the
first argument is a properly formatted config key. And as config keys
_must_ have a dot in their name, any value without a dot would have been
discarded by git-config(1) previous to this change. Thus, given that
none of the subcommands do have a dot, they are unambiguous.
Introduce the first such new subcommand, which is "git config list". To
retain backwards compatibility we only conditionally use subcommands and
will fall back to the old syntax in case no subcommand was detected.
This should help to transition to the new-style syntax until we
eventually deprecate and remove the old-style syntax.
Note that the way we handle this we're duplicating some functionality
across old and new syntax. While this isn't pretty, it helps us to
ensure that there really is no change in behaviour for the old syntax.
Amend tests such that we run them both with old and new style syntax.
As tests are now run twice, state from the first run may be still be
around in the second run and thus cause tests to fail. Add cleanup logic
as required to fix such tests.

There's quite a bunch of options to git-config(1) that allow the user to

options. The logic to handle this is thus by necessity also quite

The git-config(1) command has various different modes which are
accessible via e.g. `--get-urlmatch` or `--unset-all`. These modes are
declared with `OPT_BIT()`, which causes two minor issues:
- The respective modes also have a negated form `--no-get-urlmatch`,
which is unintended.
- We have to manually handle exclusiveness of the modes.
Switch these options to instead use `OPT_CMDMODE()`, which is made
exactly for this usecase. Remove the now-unneeded check that only a
single mode is given, which is now handled by the parse-options
interface.
While at it, format optional placeholders for arguments to conform to
our style guidelines by using `[<placeholder>]`.

The ownership of memory returned when preparing a comment string is
quite intricate: when the returned value is different than the passed
value, then the caller is responsible to free the memory. This is quite
subtle, and it's even easier to miss because the returned value is in
fact a `const char *`.
Adapt the function to always return either `NULL` or a newly allocated
string. The function is called at most once per git-config(1), so it's
not like this micro-optimization really matters. Thus, callers are now
always responsible for freeing the value.

This is the second and final preparatory commit for making the
trailer_info struct private to the trailer implementation.
Make trailer_info_get() do the actual work of allocating a new
trailer_info struct, and return a pointer to it. Because
parse_trailers() wraps around trailer_info_get(), it too can return this
pointer to the caller. From the trailer API user's perspective, the call
to trailer_info_new() can be replaced with parse_trailers(); do so in
interpret-trailers.
Because trailer_info_new() is no longer called by interpret-trailers,
remove this function from the trailer API.
With this change, we no longer allocate trailer_info on the stack ---
all uses of it are via a pointer where the actual data is always
allocated at runtime through trailer_info_new(). Make
trailer_info_release() free this dynamically allocated memory.
Finally, due to the way the function signatures of parse_trailers() and
trailer_info_get() have changed, update the callsites in
format_trailers_from_commit() and trailer_iterator_init() accordingly.

Instead of directly accessing trailer_info members, access them
indirectly through new helper functions exposed by the trailer API.
This is the first of two preparatory commits which will allow us to
use the so-called "pimpl" (pointer to implementation) idiom for the
trailer API, by making the trailer_info struct private to the trailer
implementation (and thus hidden from the API).

In https://github.com/microsoft/git/issues/623, it was reported that
maintenance stops on a missing repository, omitting the remaining
repositories that were scheduled for maintenance.
This is undesirable, as it should be a best effort type of operation.
It should still fail due to the missing repository, of course, but not
leave the non-missing repositories in unmaintained shapes.
Let's use `for-each-repo`'s shiny new `--keep-going` option that we just
introduced for that very purpose.

In https://github.com/microsoft/git/issues/623, it was reported that
the regularly scheduled maintenance stops if one repo in the middle of
the list was found to be missing.
This is undesirable, and points out a gap in the design of `git
for-each-repo`: We need a mode where that command does not stop on an
error, but continues to try running the specified command with the other
repositories.
Imitating the `--keep-going` option of GNU make, this commit teaches
`for-each-repo` the same trick: to continue with the operation on all
the remaining repositories in case there was a problem with one
repository, still setting the exit code to indicate an error occurred.

In the previous step, the "--rfc" option of "format-patch" learned
to take an optional string value to prepend to the subject prefix,
so that --rfc=WIP can give "[WIP PATCH]".
There may be cases in which the extra string wants to come after the
subject prefix. Extend the mechanism to allow "--rfc=-(WIP)" [*] to
signal that the extra string is to be appended instead of getting
prepended, resulting in "[PATCH (WIP)]".
In the documentation, discourage (ab)using "--rfc=-RFC" to say
"[PATCH RFC]" just to be different, when "[RFC PATCH]" is the norm.

* The syntax takes inspiration from Perl's open syntax that opens
pipes "open fh, '|-', 'cmd'", where the dash signals "the other

With the "--rfc" option, we can tweak the "[PATCH]" (or whatever
string specified with the "--subject-prefix" option, instead of
"PATCH") that we prefix the title of the commit with into "[RFC
PATCH]", but some projects may want "[rfc PATCH]". Adding a new
option, e.g., "--rfc-lowercase", to support such need every time
somebody wants to use different strings would lead to insanity of
accumulating unbounded number of such options.
Allow an optional value specified for the option, so that users can
use "--rfc=rfc" (think of "--rfc" without value as a short-hand for
"--rfc=RFC") if they wanted to.
This can of course be (ab)used to make the prefix "[WIP PATCH]" by
passing "--rfc=WIP". Passing an empty string, i.e., "--rfc=", is
the same as "--no-rfc" to override an option given earlier on the
same command line.

This behaviour dates back to the addition of the feature in 41a28eb6c1

Adding the "--binary" option of "diff-tree" fixes this. The "diff-tree" call

This topic addresses two CVEs:
- CVE-2024-32020:
Local clones may end up hardlinking files into the target repository's
object database when source and target repository reside on the same
disk. If the source repository is owned by a different user, then
those hardlinked files may be rewritten at any point in time by the
untrusted user.
- CVE-2024-32021:
When cloning a local source repository that contains symlinks via the
filesystem, Git may create hardlinks to arbitrary user-readable files
on the same filesystem as the target repository in the objects/
directory.

Critical security issues typically combine relatively common
vulnerabilities such as case confusion in file paths with other
weaknesses in order to raise the severity of the attack.
One such weakness that has haunted the Git project in many a
submodule-related CVE is that any hooks that are found are executed
during a clone operation. Examples are the `post-checkout` and
`fsmonitor` hooks.
However, Git's design calls for hooks to be disabled by default, as only
disabled example hooks are copied over from the templates in
`<prefix>/share/git-core/templates/`.
As a defense-in-depth measure, let's prevent those hooks from running.
Obviously, administrators can choose to drop enabled hooks into the
template directory, though, _and_ it is also possible to override
`core.hooksPath`, in which case the new check needs to be disabled.
