5a31252702 whatchanged: hint about git-log(1) and aliasing
There have been quite a few `--i-still-use-this` user reports since Git
2.51.0 was released.[1][2]  And it doesn’t seem like they are reading
the man page about the git-log(1) equivalent.

Tell them what options to plug into git-log(1), either as a replacement
command or as an alias.[3]  That template produces almost the same
output[4] and is arguably a plug-in replacement.  Concretely, add
an optional `hint` argument so that we can use it right after the
initial error line.

Also mention the same concrete options in the documentation while we’re
at it.

3c07063231 refs/files: catch conflicts on case-insensitive file-systems
During the 'prepare' phase of a reference transaction in the files
backend, we create the lock files for references to be created. When
using batched updates on case-insensitive filesystems, the entire
batched updates would be aborted if there are conflicting names such as:

  refs/heads/Foo
  refs/heads/foo

This affects all commands which were migrated to use batched updates in
Git 2.51, including 'git-fetch(1)' and 'git-receive-pack(1)'. Before
that, reference updates would be applied serially with one transaction
used per update. When users fetched multiple references on
case-insensitive systems, subsequent references would simply overwrite
any earlier references. So when fetching:

  refs/heads/foo: 5f34ec0bfeac225b1c854340257a65b106f70ea6
  refs/heads/Foo: ec3053b0977e83d9b67fc32c4527a117953994f3
  refs/heads/sample: 2eefd1150e06d8fca1ddfa684dec016f36bf4e56

The user would simply end up with:

  refs/heads/foo: ec3053b0977e83d9b67fc32c4527a117953994f3
  refs/heads/sample: 2eefd1150e06d8fca1ddfa684dec016f36bf4e56

This is buggy behavior since the user is never informed about the
overrides performed and missing references. Nevertheless, the user is
left with a working repository with a subset of the references. Since
Git 2.51, in such situations fetches would simply fail without updating
any references. Which is also buggy behavior and worse off since the
user is left without any references.

The error is triggered in `lock_raw_ref()` where the files backend
attempts to create a lock file. When a lock file already exists the
function returns a 'REF_TRANSACTION_ERROR_GENERIC'. When this happens,
the entire batched updates, not individual operation, is aborted as if
it were in a transaction.

Change this to return 'REF_TRANSACTION_ERROR_CASE_CONFLICT' instead to
aid the batched update mechanism to simply reject such errors. The
change only affects batched updates since batched updates will reject
individual updates with non-generic errors. So specifically this would
only affect:

    1. git fetch
    2. git receive-pack
    3. git update-ref --batch-updates

This bubbles the error type up to `files_transaction_prepare()` which
tries to lock each reference update. So if the locking fails, we check
if the rejection type can be ignored, which is done by calling
`ref_transaction_maybe_set_rejected()`.

As the error type is now 'REF_TRANSACTION_ERROR_CASE_CONFLICT',
the specific reference update would simply be rejected, while other
updates in the transaction would continue to be applied. This allows
partial application of references in case-insensitive filesystems when
fetching colliding references.

While the earlier implementation allowed the last reference to be
applied overriding the initial references, this change would allow the
first reference to be applied while rejecting consequent collisions.
This should be an okay compromise since with the files backend, there is
no scenario possible where we would retain all colliding references.

Let's also be more proactive and notify users on case-insensitive
filesystems about such problems by providing a brief about the issue
while also recommending using the reftable backend, which doesn't have
the same issue.

e1d062e8ba odb: drop deprecated wrapper functions
In the Git 2.51 release cycle we've refactored the object database layer
to access objects via `struct object_database` directly. To make the
transition a bit easier we have retained some of the old-style functions
in case those were widely used.

Now that Git 2.51 has been released it's time to clean up though and
drop these old wrappers. Do so and adapt the small number of newly added
users to use the new functions instead.

89b4183efe stash: pass --no-color to diff plumbing child processes
After a partial stash, we may clear out the working tree by capturing
the output of diff-tree and piping it into git-apply (and likewise we
may use diff-index to restore the index). So we most definitely do not
want color diff output from that diff-tree process.  And it normally
would not produce any, since its stdout is not going to a tty, and the
default value of color.ui is "auto".

However, if GIT_PAGER_IN_USE is set in the environment, that overrides
the tty check, and we'll produce a colorized diff that chokes git-apply:

  $ echo y | GIT_PAGER_IN_USE=1 git stash -p
  [...]
  Saved working directory and index state WIP on main: 4f2e2bb foo
  error: No valid patches in input (allow with "--allow-empty")
  Cannot remove worktree changes

Setting this variable is a relatively silly thing to do, and not
something most users would run into. But we sometimes do it in our tests
to stimulate color. And it is a user-visible bug, so let's fix it rather
than work around it in the tests.

The root issue here is that diff-tree (and other diff plumbing) should
probably not ever produce color by default. It does so not by parsing
color.ui, but because of the baked-in "auto" default from 4c7f1819b3
(make color.ui default to 'auto', 2013-06-10). But changing that is
risky; we've had discussions back and forth on the topic over the years.
E.g.:

  https://lore.kernel.org/git/86D0A377-8AFD-460D-A90E-6327C6934DFC@gmail.com/.

So let's accept that as the status quo for now and protect ourselves by
passing --no-color to the child processes. This is the same thing we did
for add-interactive itself in 1c6ffb546b (add--interactive.perl: specify
--no-color explicitly, 2020-09-07).

e1d3d61a45 diff: --no-index should ignore the worktree
The act of giving "--no-index" tells Git to pretend that the current
directory is not under control of any Git index or repository, so
even when you happen to be in a Git controlled working tree, where
in that working tree should not matter.

But the start-up sequence tries to discover the top of the working
tree and chdir(2)'s there, even before Git passes control to the
subcommand being run.  When diff_no_index() starts running, it
starts at a wrong (from the end-user's point of view who thinks
"git diff --no-index" is merely a better version of GNU diff)
directory, and the original directory the user started the command
is at "prefix".

Because the paths given from argv[] have already been adjusted to
account for this path shuffling by prepending the prefix, and
showing the resulting path by stripping the prefix, the effect of
these nonsense operations (nonsense in the context of "--no-index",
that is) is usually not observable.

Except for special cases like "-", where it is not preprocessed by
prepending the prefix.

Instead of papering over by adding more special cases only to cater
to the no-index codepath in the generic code, drive the diff
machinery more faithfully to what is going on.  If the user started
"git diff --no-index" in directory X/Y/Z in a working tree
controlled by Git, and the start up sequence of Git chdir(2)'ed up
to directory X and left Y/Z in the prefix, revert the effect of the
start up sequence by chdir'ing back to Y/Z and emptying the prefix.

7aa619c36f builtin/reflog: implement subcommand to write new entries
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.

649c7bb77a builtin/reflog: improve grouping of subcommands
The way subcommands of git-reflog(1) are laid out does not make any
immediate sense. Reorder them such that read-only subcommands precede
writing commands for a bit more structure.

Furthermore, move the "expire" subcommand last. This prepares for a
subsequent change where we are about to introduce a new "write" command
to append reflog entries. Like this, the writing subcommands are ordered
such that those affecting a single reflog come before those spanning
across all reflogs.

eb883b05da remote: bail early from set_head() if missing remote name
In "git remote set-head", we can take varying numbers of arguments
depending on whether we saw the "-d" or "-a" options. But the first
argument is always the remote name.

The current code is somewhat awkward in that it conditionally handles
the remote name up-front like this:

  if (argc)
     remote = ...from argv[0]...

and then only later decides to bail if we do not have the right number
of arguments for the options we saw.

This makes it hard to figure out if "remote" is always set when it needs
to be. Both for humans, but also for compilers; with -Og, gcc complains
that "remote" can be accessed without being initialized (although this
is not true, as we'd always die with a usage message in that case).

Let's instead enforce the presence of the remote argument up front,
which fixes the compiler warning and is easier to understand. It does
mean duplicating the code to print a usage message, but it's a single
line.

1bad05bacc revert: initialize const value
When building with clang-22 and DEVELOPER=1 mode, this warning causes us
to fail compilation:

  builtin/revert.c:114:13: error: default initialization of an object of type 'const char' leaves the object uninitialized [-Werror,-Wdefault-const-init-var-unsafe]
    114 |         const char sentinel_value;
        |                    ^

The compiler is right that this code is a bit funny. We declare a const
value without an initializer. It cannot be assigned to because of the
const, but without an initializer it has no predictable value. So as a
variable it can never have any useful function, and if we tried to look
at it, we'd get undefined behavior.

But it does have a function. We never use its value, but rather use its
address as a sentinel value for some other variables:

        const char *gpg_sign = &sentinel_value;

	...maybe set gpg_sign via parse_options...

	if (gpg_sign != &sentinel_value)
		...we got a non-default value...

Normally we'd use NULL as a sentinel value for a pointer, but it doesn't
work here because we also want to detect --no-gpg-sign, which is marked
by setting the pointer to NULL. We need a separate "this was not
touched" value, which is what this sentinel variable gives us.

So the code is correct as-is, but the sentinel variable itself is funny
enough that it's understandable for a compiler warning to flag it. Let's
try to appease the compiler.

There are a few possible options:

  1. Instead of a variable, we could just construct an artificial
     sentinel address like "1", "-1", etc. I think these technically
     fall afoul of the C standard (even if we do not access them, even
     constructing invalid pointers is not always allowed). But it's also
     something we do elsewhere, and even happens in some standard
     interfaces (e.g., mmap()'s MMAP_FAILED value). It does involve some
     annoying casts, though.

  2. We can mark it as static. That gives it a definite value, but
     perhaps makes people wonder if the static-ness is important, when
     it's not.

  3. We can just give it a value to shut the compiler up, even though
     nobody cares about that value.

I went with (3) here as the smallest and most obvious change.

2b3ae04011 add-patch: add diff.context command line overrides
This patch compliments the previous commit, where builtins that use
add-patch infrastructure now respect diff.context and
diff.interHunkContext file configurations.

In particular, this patch helps users who don't want to set persistent
context configurations or just want a way to override them on a one-time
basis, by allowing the relevant builtins to accept corresponding command
line options that override the file configurations.

This mimics commands such as diff and log, which allow for both context
file configuration and command line overrides.

7e2943128e blame: remove parameter detailed in get_commit_info()
The get_commit_info() function accepts a parameter that can be used
to stop the commit parsing early.  However, none of the callers use
this feature, and testing proved that the performance gain of
stopping parsing early is negligible and unmeasurable.

fa0f4e46f5 for-each-ref: reword the documentation for '--start-after'
The documentation for '--start-after' states that the flag cannot be
used with general pattern matching. This is a bit vague, since there is
no clear understanding about what 'general' means here. Rewrite the
sentence to be more specific.

While here, fix a typo in the 'OPT_STRING'.

bb10dcf573 submodule: skip redundant active entries when pattern covers path
configure_added_submodule always writes an explicit
submodule.<name>.active entry, even when the new
path is already matched by submodule.active
patterns. This leads to unnecessary and cluttered configuration.

change the logic to centralize wildmatch-based pattern lookup,
in configure_added_submodule. Wrap the active-entry write in a conditional
that only fires when that helper reports no existing pattern covers the
submodule’s path.

1fa06ceddf submodule: prevent overwriting .gitmodules on path reuse
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).

08b775864e config: move Git config parsing into "environment.c"
In "config.c" we host both the business logic to read and write config
files as well as the logic to parse specific Git-related variables. On
the one hand this is mixing concerns, but even more importantly it means
that we cannot easily remove the dependency on `the_repository` in our
config parsing logic.

Move the logic into "environment.c". This file is a grab bag of all
kinds of global state already, so it is quite a good fit. Furthermore,
it also hosts most of the global variables that we're parsing the config
values into, making this an even better fit.

Note that there is one hidden change: in `parse_fsync_components()` we
use an `int` to iterate through `ARRAY_SIZE(fsync_component_names)`. But
as -Wsign-compare warnings are enabled in this file this causes a
compiler warning. The issue is fixed by using a `size_t` instead.

This change allows us to drop the `USE_THE_REPOSITORY_VARIABLE`
declaration.

In 036876a106 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.

Follow through with that intent and remove `git_config_set_multivar()`.
All callsites are adjusted so that they use
`repo_config_set_multivar(the_repository, ...)` instead. While some
callsites might already have a repository available, this mechanical
conversion is the exact same as the current situation and thus cannot
cause any regression. Those sites should eventually be cleaned up in a
later patch series.
