The previous commit added tests for shadowing deprecated builtins.
Let’s make the test suite more complete by exercising a sample of
the builtins and in turn test the documentation for git-config(1):
To avoid confusion and troubles with script usage, aliases that hide
existing Git commands are ignored except for deprecated commands.

git-whatchanged(1) is deprecated and you need to pass
`--i-still-use-this` in order to force it to work as before.
There are two affected users, or usages:
1. people who use the command in scripts; and
2. people who are used to using it interactively.
For (1) the replacement is straightforward.[1] But people in (2) might
like the name or be really used to typing it.[3]
An obvious first thought is to suggest aliasing `whatchanged` to the
git-log(1) equivalent.[1] But this doesn’t work and is awkward since you
cannot shadow builtins via aliases.
Now you are left in an uncomfortable limbo; your alias won’t work until
the command is removed for good.
Let’s lift this limitation by allowing *deprecated* builtins to be
shadowed by aliases.
The only observed demand for aliasing has been for git-whatchanged(1),
not for git-pack-redundant(1). But let’s be consistent and treat all
deprecated commands the same.
[1]:
git log --raw --no-merges
With a minor caveat: you get different outputs if you happen to
have empty commits (no changes)[2]

In addition to the regular trace information produced by
CURLOPT_VERBOSE, recent curl versions can enable or disable tracing of
specific subsystems using a call to curl_global_trace().
This level of detail may or may not be useful for us in Git as mere
users of libcurl, but there's one case where we need it for a test. In
t5564, we set up a socks proxy, access it with GIT_TRACE_CURL set, and
expect to find socks-related messages in the output. This test is broken
in the release candidates for libcurl 8.16, as those socks messages are
no longer produced in the trace.
The problem bisects to curl's commit ab5e0bfddc (pytest: add SOCKS tests
and scoring, 2025-07-21). There the socks messages were moved from
generic infof() messages to the component-specific CURL_TRC_CF() system.
And so we do not see them by default, but only if "socks" is enabled as
a logging component.
Teach Git's http code to accept a component list from the
environment and pass it into curl_global_trace(). We can then use
that in the test to enable the correct component.
It should be safe to do so unconditionally. In older versions of curl
which don't support this call, setting the environment variable is a
noop. Likewise, any versions of curl which don't recognize the "socks"
component should silently ignore it. The manpage for curl_global_trace()
says this:
The config string is a list of comma-separated component names. Names
are case-insensitive and unknown names are ignored. The special name
"all" applies to all components. Names may be prefixed with '+' or '-'
to enable or disable detailed logging for a component.
The list of component names is not part of curl's public API. Names may
be added or disappear in future versions of libcurl. Since unknown
names are silently ignored, outdated log configurations does not cause
errors when upgrading libcurl. Given that, some names can be expected
to be fairly stable and are listed below for easy reference.
So this should let us make the test work on all versions without
worrying about confusing older (or newer) versions. For the same reason,
I've opted not to document this interface. This is deep internal voodoo
for which we can make no promises to users. In fact, I was tempted to
simply hard-code "socks" to let our test pass and not expose anything.
But I suspect a little run-time flexibility may come in handy in the
future when debugging or dealing with similar logging issues.
I also considered just putting "all" into such a hard-coded default. But
if you try it, you will see that many of the components are quite
verbose and likely not interesting. They would clutter up our trace
output if we enabled them by default.

"make -JN" with INCLUDE_LIBGIT_RS enabled causes cargo lock warnings
and can trigger ld errors during the build.
The build errors are caused by two inner "make" invocations getting
triggered concurrently: once inside of libgit-sys and another inside of
libgit-rs.
Make libgit-rs depend on libgit-sys so that "make" prevents them
from running concurrently. Apply the same logic to the test invocations.
Use cargo's "--manifest-path" option instead of "cd" in the recipes.

When migrating reflog entries between different storage formats we end
up with invalid old object IDs for the migrated entries: instead of
writing the old object ID of the to-be-migrated entry, we end up with
the all-zeroes object ID.
The root cause of this issue is that we don't know to use the old object
ID provided by the caller. Instead, we manually resolve the old object
ID by resolving the current value of its matching reference. But as that
reference does not yet exist in the target ref storage we always end up
resolving it to all-zeroes.
This issue got unnoticed as there is no user-facing command that would
even show the old object ID. While `git log -g` knows to show the new
object ID, we don't have any formatting directive to show the old object
ID.
Fix the bug by introducing a new flag `REF_LOG_USE_PROVIDED_OIDS`. If
set, backends are instructed to use the old and new object IDs provided
by the caller, without doing any manual resolving. Set this flag in
`ref_transaction_update_reflog()`.
Amend our tests in t1460-refs-migrate to use our test tool to read
reflog entries. This test tool prints out both old and new object ID of
each reflog entry, which fixes the test gap. Furthermore it also prints
the full identity used to write the reflog, which provides test coverage
for the previous commit in this patch series that fixed the identity for
migrated reflogs.

While we provide a couple of subcommands in git-reflog(1) to remove
reflog entries, we don't provide any to write new entries. Obviously
this is not an operation that really would be needed for many use cases
out there, or otherwise people would have complained that such a command
does not exist yet. But the introduction of the "reftable" backend
changes the picture a bit, as it is now basically impossible to manually
append a reflog entry if one wanted to do so due to the binary format.
Plug this gap by introducing a simple "write" subcommand. For now, all
this command does is to append a single new reflog entry with the given
object IDs and message to the reflog. More specifically, it is not yet
possible to:
- Write multiple reflog entries at once.
- Insert reflog entries at arbitrary indices.
- Specify the date of the reflog entry.
- Insert reflog entries that refer to nonexistent objects.
If required, those features can be added at a future point in time. For
now though, the new command aims to fulfill the most basic use cases
while being as strict as possible when it comes to verifying parameters.

The "clar-decls.h" header gets generated by us to extract prototypes of
unit test functions from our clar-based tests. This generated file is
then written into "t/unit-tests/" and included via "unit-test.h". The
intent of all this is that we can keep "-Wmissing-prototype" warnings
enabled. If we had that warning disabled, it would be easy to miss in
case any of the non-static functions had a typo in its name and thus
wasn't picked up by our test case extractor.
Including the file directly has a big downside though: if a source tree
was built both with our Makefile and with Meson, then the Meson build
would include the "clar-decls.h" file from our Makefile. And if those
are out of sync we get compiler errors.
We already fixed a similar issue in 4771501c0a (meson: ensure correct
version-def.h is used, 2025-01-14). Let's do the same and pass the

Adding a submodule at a path that previously hosted
another submodule (e.g., 'child') reuses the submodule
name derived from the path. If the original submodule
was only moved (e.g., to 'child_old') and not renamed,
this silently overwrites its configuration in .gitmodules.
This behavior loses user configuration and causes
confusion when the original submodule is expected
to remain intact. It assumes that the path-derived
name is always safe to reuse, even though the name
might still be in use elsewhere in the repository.
Teach module_add() to check if the computed submodule
name already exists in the repository's submodule config,
and if so, refuse the operation unless the user explicitly
renames the submodule or uses the --force option,
which will automatically generate a unique name by
appending a number (e.g., child1).

The old `lib-reftable.{c,h}` implemented helper functions for our
homegrown unit-testing framework. As part of migrating reftable-related
tests to the Clar framework, Clar-specific versions of these functions
in `lib-reftable-clar.{c,h}` were introduced.
Now that all test files using these helpers have been converted to Clar,
we can safely remove the original `lib-reftable.{c,h}` and rename the
Clar- specific versions back to `lib-reftable.{c,h}`. This restores a
clean and consistent naming scheme for shared test utilities.
Finally, update our build system to reflect the changes made and remove
redundant code related to the reftable tests and our old homegrown
unit-testing setup. `test-lib.{c,h}` remains unchanged in our build
system as some files particularly `t/helper/test-example-tap.c` depends
