git merge-file knows how to merge files on the file system already. It
would be helpful, however, to allow it to also merge single blobs.
Teach it an `--object-id` option which means that its arguments are
object IDs and not files to allow it to do so.
We handle the empty blob specially since read_mmblob doesn't read it
directly and otherwise users cannot specify an empty ancestor.

While we have multiple ways to show the value of a given reference, we
do not have any way to check whether a reference exists at all. While
commands like git-rev-parse(1) or git-show-ref(1) can be used to check
for reference existence in case the reference resolves to something
sane, neither of them can be used to check for existence in some other
scenarios where the reference does not resolve cleanly:
- References which have an invalid name cannot be resolved.
- References to nonexistent objects cannot be resolved.
- Dangling symrefs can be resolved via git-symbolic-ref(1), but this
requires the caller to special case existence checks depending on
whether or not a reference is symbolic or direct.
Furthermore, git-rev-list(1) and other commands do not let the caller
distinguish easily between an actually missing reference and a generic
error.
Taken together, this seems like sufficient motivation to introduce a
separate plumbing command to explicitly check for the existence of a
reference without trying to resolve its contents.
This new command comes in the form of `git show-ref --exists`. This
new mode will exit successfully when the reference exists, with a
specific exit code of 2 when it does not exist, or with 1 when there
has been a generic error.
Note that the only way to properly implement this command is by using
the internal `refs_read_raw_ref()` function. While the public function
`refs_resolve_ref_unsafe()` can be made to behave in the same way by
passing various flags, it does not provide any way to obtain the errno
with which the reference backend failed when reading the reference. As
such, it becomes impossible for us to distinguish generic errors from
the explicit case where the reference wasn't found.

The synopsis treats the `--verify` and the implicit mode the same. They
are slightly different though:
- They accept different sets of flags.
- The implicit mode accepts patterns while the `--verify` mode
accepts references.
Split up the synopsis for these two modes such that we can disambiguate
those differences.
While at it, drop "--quiet" from the pattern mode's synopsis. It does
not make a lot of sense to list patterns, but squelch the listing output
itself. The description for "--quiet" is adapted accordingly.

The git-show-ref(1) command has three different modes, of which one is
implicit and the other two can be chosen explicitly by passing a flag.
But while these modes are standalone and cause us to execute completely
separate code paths, we gladly accept the case where a user asks for
both `--exclude-existing` and `--verify` at the same time even though it
is not obvious what will happen. Spoiler: we ignore `--verify` and
execute the `--exclude-existing` mode.
Let's explicitly detect this invalid usage and die in case both modes
were requested.

The `show_one()` function implicitly receives a bunch of options which
are tracked via global variables. This makes it hard to see which
subcommands of git-show-ref(1) actually make use of these options.
Introduce a `show_one_options` structure that gets passed down to this
function. This allows us to get rid of more global state and makes it
more explicit which subcommands use those options.

When passing patterns to git-show-ref(1) we're checking whether any
reference matches -- if none do, we indicate this condition via an
unsuccessful exit code.
We're using a global variable to count these matches, which is required
because the counter is getting incremented in a callback function. But
now that we have the `struct show_ref_data` in place, we can get rid of
the global variable and put the counter in there instead.

It's not immediately obvious options which options are applicable to
what subcommand in git-show-ref(1) because all options exist as global
state. This can easily cause confusion for the reader.
Refactor options for the `--exclude-existing` subcommand to be contained
in a separate structure. This structure is stored on the stack and
passed down as required. Consequently, it clearly delimits the scope of
those options and requires the reader to worry less about global state.

When passing patterns to `git show-ref` we have some code that will
cause us to die if `verify && !quiet` is true. But because `verify`
indicates a different subcommand of git-show-ref(1) that causes us to
execute `cmd_show_ref__verify()` and not `cmd_show_ref__patterns()`, the
condition cannot ever be true.
Let's remove this dead code.

While not immediately obvious, git-show-ref(1) actually implements three
different subcommands:
- `git show-ref <patterns>` can be used to list references that
match a specific pattern.
- `git show-ref --verify <refs>` can be used to list references.
These are _not_ patterns.
- `git show-ref --exclude-existing` can be used as a filter that
reads references from standard input, performing some conversions
on each of them.
Let's make this more explicit in the code by splitting up the three
subcommands into separate functions. This also allows us to address the
confusingly named `patterns` variable, which may hold either patterns or
reference names.

The `pattern` variable is a global variable that tracks either the
reference names (not patterns!) for the `--verify` mode or the patterns
for the non-verify mode. This is a bit confusing due to the slightly
different meanings.
Convert the variable to be local. While this does not yet fix the double
meaning of the variable, this change allows us to address it in a
subsequent patch more easily by explicitly splitting up the different
subcommands of git-show-ref(1).
Note that we introduce a `struct show_ref_data` to pass the patterns to
`show_ref()`. While this is overengineered now, we will extend this
structure in a subsequent patch.

The `--missing` object option in rev-list currently works only with
missing blobs/trees. For missing commits the revision walker fails with
a fatal error.
Let's extend the functionality of `--missing` option to also support
commit objects. This is done by adding a `missing_objects` field to
`rev_info`. This field is an `oidset` to which we'll add the missing
commits as we encounter them. The revision walker will now continue the
traversal and call `show_commit()` even for missing commits. In rev-list
we can then check if the commit is a missing commit and call the
existing code for parsing `--missing` objects.
A scenario where this option would be used is to find the boundary
objects between different object directories. Consider a repository with
a main object directory (GIT_OBJECT_DIRECTORY) and one or more alternate
object directories (GIT_ALTERNATE_OBJECT_DIRECTORIES). In such a
repository, using the `--missing=print` option while disabling the
alternate object directory allows us to find the boundary objects
between the main and alternate object directory.

in the upcoming commit, we'll also add a dependency on
`finish_object__ma()`. Since in C symbols must be declared before
they're used, let's move `show_commit()` below both `finish_commit()`
and `finish_object__ma()`, so the code is cleaner as a whole without the

The bit `do_not_die_on_missing_tree` is used in revision.h to ensure the
revision walker does not die when encountering a missing tree. This is
currently exclusively set within `builtin/rev-list.c` to ensure the
`--missing` option works with missing trees.
In the upcoming commits, we will extend `--missing` to also support
missing commits. So let's rename the bit to
`do_not_die_on_missing_objects`, which is object type agnostic and can
be used for both trees/commits.

33d7bdd645 (builtin/reflog.c: use parse-options api for expire, delete
subcommands, 2022-01-06) broke the option --single-worktree of git
reflog expire and added a non-printable short flag for it, presumably by
accident. While before it set the variable "all_worktrees" to 0, now it
sets it to 1, its default value. --no-single-worktree is required now
to set it to 0.
Fix it by replacing the variable with one that has the opposite meaning,
to avoid the negation and its potential for confusion. The new variable
"single_worktree" directly captures whether --single-worktree was given.
Also remove the unprintable short flag SOH (start of heading) because it
is undocumented, hard to use and is likely to have been added by mistake
in connection with the negation bug above.

Let the parse-options code detect and handle the use of options that are
incompatible with --show-current-patch. This requires exposing the
distinction between the "raw" and "diff" sub-modes. Do that by
splitting the mode RESUME_SHOW_PATCH into RESUME_SHOW_PATCH_RAW and
RESUME_SHOW_PATCH_DIFF and stop tracking sub-modes in a separate struct.
The result is a simpler callback function and more precise error
messages. The original reports a spurious argument or a NULL pointer:
$ git am --show-current-patch --show-current-patch=diff
error: options '--show-current-patch=diff' and '--show-current-patch=raw' cannot be used together
$ git am --show-current-patch=diff --show-current-patch
error: options '--show-current-patch=(null)' and '--show-current-patch=diff' cannot be used together
With this patch we get the more precise:
$ git am --show-current-patch --show-current-patch=diff
error: --show-current-patch=diff is incompatible with --show-current-patch
$ git am --show-current-patch=diff --show-current-patch
error: --show-current-patch is incompatible with --show-current-patch=diff

The description of the `git bisect run` command syntax at the beginning
of the manpage is `git bisect run <cmd>...`, which isn't quite clear
about what `<cmd>` is or what the `...` mean; one could think that it is
the whole (quoted) command line with all arguments in a single string,
or that it supports multiple commands, or that it doesn't accept
commands with arguments at all.
Change to `git bisect run <cmd> [<arg>...]` to clarify the syntax,
in both the manpage and the `git bisect -h` command output.
Additionally, change `--term-{new,bad}` et al to `--term-(new|bad)`
for consistency with the synopsis syntax conventions.

The code's evolution left in some bits surrounding enum rebase_type that
don't really make sense any more. In particular, it makes no sense to
invoke imply_merge() if the type is already known not to be
REBASE_APPLY, and it makes no sense to assign the type after calling
imply_merge().
enum rebase_type had more values until commit a74b35081c ("rebase: drop

These error messages say "new_index" as if that spelling has some
significance to the end users (e.g. the file "$GIT_DIR/new_index"
has some issues), but that is not the case at all. The i18n folks
were made to include the word literally in the translated messages,
which was not a good idea at all. Spell it "new index", as we are
just telling the users that we failed to create a new index file.
The term is expected to be translated to the end-users' languages,
not left as if it were a literal file name.
This dates all the way back to the first re-implemenation of "git

"git stash store" is meant to store what "git stash create"
produces, as these two are implementation details of the end-user
facing "git stash save" command. Even though it is clearly
documented as such, users would try silly things like "git stash
store HEAD" to render their stash unusable.
Worse yet, because "git stash drop" does not allow such a stash
entry to be removed, "git stash clear" would be the only way to
recover from such a mishap. Reuse the logic that allows "drop" to
refrain from working on such a stash entry to teach "store" to avoid
storing an object that is not a stash entry in the first place.

When mostly the same set of options are to be used to perform
multiple merges, one instance of the merge_options structure may
want to be created and used by copying from the same template
instance. We saw such a use recently in "git merge-tree".
Let's make the pattern official by introducing copy_merge_options()
as a supported way to make a copy of the structure, and also give
clear_merge_options() to release any resources held by a copied
instance. Currently we only make a shallow copy, so the former is a
mere structure assignment while the latter is a no-op, but this may
change in the future as the members of merge_options structure
evolve.
