The 'git-maintenance(1)' command supports an '--auto' flag. Usage of the
flag ensures to run maintenance tasks only if certain thresholds are
met. The heuristic is defined on a task level, wherein each task defines
an 'auto_condition', which states if the task should be run.
The 'pack-refs' task is hard-coded to return 1 as:
1. There was never a way to check if the reference backend needs to be
optimized without actually performing the optimization.
2. We can pass in the '--auto' flag to 'git-pack-refs(1)' which would
optimize based on heuristics.
The previous commit added a `refs_optimize_required()` function, which
can be used to check if a reference backend required optimization. Use
this within `pack_refs_condition()`.
This allows us to add a 'git maintenance is-needed' subcommand which can
notify the user if maintenance is needed without actually performing the
optimization. Without this change, the reference backend would always
state that optimization is needed.
Since we import 'revision.h', we need to remove the definition for
'SEEN' which is duplicated in the included header.

The reftable backend performs auto-compaction as part of its regular
flow, which is required to keep the number of tables part of a stack at
bay. This allows it to stay optimized.
Compaction can also be triggered voluntarily by the user via the 'git
pack-refs' or the 'git refs optimize' command. However, currently there
is no way for the user to check if optimization is required without
actually performing it.
Extract out the heuristics logic from 'reftable_stack_auto_compact()'
into an internal function 'update_segment_if_compaction_required()'.
Then use this to add and expose `reftable_stack_compaction_required()`
which will allow users to check if the reftable backend can be
optimized.

The `stack_table_sizes_for_compaction()` function returns individual
sizes of each reftable table. This function is only called by
`reftable_stack_auto_compact()` to decide which tables need to be
compacted, if any.
Modify the function to directly return the segments, which avoids the
extra step of receiving the sizes only to pass it to
`suggest_compaction_segment()`.
A future commit will also add functionality for checking whether
auto-compaction is necessary without performing it. This change allows

The `struct ref_store` variable exposes two ways to optimize a reftable
backend:
1. pack_refs
2. optimize
The former was specific to the 'files' + 'packed' refs backend. The
latter is more generic and covers all backends. While the naming is
different, both of these functions perform the same functionality.
Consolidate this code to only maintain the 'optimize' functions. Do this
by modifying the backends so that they exclusively implement the
`optimize` callback, only. All users of the refs subsystem already use
the 'optimize' function so there is no changes needed on the callee
side. Finally, cleanup all references to the 'pack_refs' field of the
structure and code around it.

In 054f5f457e (ref-filter: parse objects on demand, 2025-10-23) we have
started to skip parsing some objects in case we don't need to access
their values in the first place. This was done by introducing a new
member `struct expand_data::maybe_object` that gets populated on demand
via `get_or_parse_object()`.
This has led to a regression though where the object now gets reused
because we don't reset it properly. The `oi` structure is declared in
global scope, and there is no single place where we reset it before
invoking `get_object()`. The consequence is that the `maybe_object`
member doesn't get reset across calls, so subsequent calls will end up
reusing the same object.
This is only an issue for a subset of retrieved values, as not all of
the infrastructure ends up calling `get_or_parse_object()`. So the
effect is limited, which is probably why the issue wasn't detected
earlier.
Fix the issue by resetting `maybe_object` in `get_object()`.

When formatting an arbitrary object we parse that object regardless of
whether or not we actually need any parsed data. In fact, many of the
atoms we have don't require any.
Refactor the code so that we parse the data on demand when we see an
atom that wants to access the objects. This leads to a small speedup,
for example in the Chromium repository with around 40000 refs:
Benchmark 1: for-each-ref --format='%(raw)' (HEAD~)
Time (mean ± σ): 388.7 ms ± 1.1 ms [User: 322.2 ms, System: 65.0 ms]
Range (min … max): 387.3 ms … 390.8 ms 10 runs
Benchmark 2: for-each-ref --format='%(raw)' (HEAD)
Time (mean ± σ): 344.7 ms ± 0.7 ms [User: 287.8 ms, System: 55.1 ms]
Range (min … max): 343.9 ms … 345.7 ms 10 runs
Summary
for-each-ref --format='%(raw)' (HEAD) ran
1.13 ± 0.00 times faster than for-each-ref --format='%(raw)' (HEAD~)
With this change, we now spend ~90% of the time decompressing objects,
which is almost as good as it gets regarding git-for-each-ref(1)'s own
infrastructure.

Users can ask git-for-each-ref(1) to peel tags and return information of
the tagged object by adding an asterisk to the format, like for example
"%(*$objectname)". If so, git-for-each-ref(1) peels that object to the
first non-tag object and then returns its values.
As mentioned in preceding commits, it can happen that the tagged object
type and the claimed object type differ, effectively resulting in a
corrupt tag. git-for-each-ref(1) would notice this mismatch, print an
error and then bail out when trying to peel the tag.
But we only notice this corruption in some very specific edge cases!
While we have a test in "t/for-each-ref-tests.sh" that verifies the
above scenario, this test is specifically crafted to detect the issue at
hand. Namely, we create two tags:
- One tag points to a specific object with the correct type.
- The other tag points to the *same* object with a different type.
The fact that both tags point to the same object is important here:
`peel_object()` wouldn't notice the corruption if the tagged objects
were different.
The root cause is that `peel_object()` calls `lookup_${type}()`
eventually, where the type is the same type declared in the tag object.
Consequently, when we have two tags pointing to the same object but with
different declared types we'll call two different lookup functions. The
first lookup will store the object with an unverified type A, whereas
the second lookup will try to look up the object with a different
unverified type B. And it is only now that we notice the discrepancy in
object types, even though type A could've already been the wrong type.
Fix the issue by verifying the object type in `populate_value()`. With
this change we'll also notice type mismatches when only dereferencing a
tag once.

Both the "files" and "reftable" backend store peeled object IDs for
references that point to tags:
- The "files" backend stores the value when packing refs, where each
peeled object ID is prefixed with "^".
- The "reftable" backend stores the value whenever writing a new
reference that points to a tag via a special ref record type.
Both of these backends use `peel_object()` to find the peeled object ID.
But as explained in the preceding commit, that function does not detect
the case where the tag's tagged object and its claimed type mismatch.
The consequence of storing these bogus peeled object IDs is that we're
less likely to detect such corruption in other parts of Git.
git-for-each-ref(1) for example does not notice anymore that the tag is
broken when using "--format=%(*objectname)" to dereference tags.
One could claim that this is good, because it still allows us to mostly
use the tag as intended. But the biggest problem here is that we now
have different behaviour for such a broken tag depending on whether or
not we have its peeled value in the refdb.
Fix the issue by verifying the object type when peeling the object. If
that verification fails we simply skip storing the peeled value in
either of the reference formats.

When peeling a tag to a non-tag object we repeatedly call
`parse_object()` on the tagged object until we find the first object
that isn't a tag. While this feels sensible at first, there is a big
catch here: `parse_object()` doesn't actually verify the type of the
tagged object.
The relevant code path here eventually ends up in `parse_tag_buffer()`.
Here, we parse the various fields of the tag, including the "type". Once
we've figured out the type and the tagged object ID, we call one of the
`lookup_${type}()` functions for whatever type we have found. There is
two possible outcomes in the successful case:
1. The object is already part of our cached objects. In that case we
double-check whether the type we're trying to look up matches the
type that was cached.
2. The object is _not_ part of our cached objects. In that case, we
simply create a new object with the expected type, but we don't
parse that object.
In the first case we might notice type mismatches, but only in the case
where our cache has the object with the correct type. In the second
case, we'll blindly assume that the type is correct and then go with it.
We'll only notice that the type might be wrong when we try to parse the
object at a later point.
Now arguably, we could change `parse_tag_buffer()` to verify the tagged
object's type for us. But that would have the effect that such a tag
cannot be parsed at all anymore, and we have a small bunch of tests for
exactly this case that assert we still can open such tags. So this
change does not feel like something we can retroactively tighten, even
though one shouldn't ever hit such corrupted tags.
Instead, add a new `flags` field to `peel_object()` that allows the
caller to opt in to strict object verification. This will be wired up at
a subset of callsites over the next few commits.
Note that this change also inlines `deref_tag_noverify()`. There's only
been two callsites of that function, the one we're changing and one in
our test helpers. The latter callsite can trivially use `deref_tag()`
instead, so by inlining the function we avoid having to pass down the
flag.

variable tracked the currently-active ref iterator so that we can use it

The git-show-ref(1) command has multiple different modes:
- It knows to show all references matching a pattern.
- It knows to list all references that are an exact match to whatever
the user has provided.
- It knows to check for reference existence.
The first two commands use mostly the same infrastructure to print the
references via `show_one()`. But while the former mode uses a proper
iterator and thus has a `struct reference` available in its context, the
latter calls `refs_read_ref()` and thus doesn't. Consequently, we cannot
easily use `reference_get_peeled_oid()` to print the peeled value.
Adapt the code so that we manually construct a `struct reference` when
verifying refs. We wouldn't ever have the peeled value available anyway
as we're not using an iterator here, so we can simply plug in the values
we _do_ have.
With this change we now have a `struct reference` available at both

- Once manually to announce capabilities.
When sending references to the client we also send the peeled value of
tags. As we don't have a `struct reference` available in the second
case, we cannot easily peel by calling `reference_get_peeled_oid()`, but
we instead have to depend on on global state via `peel_iterated_oid()`.
We do have a reference available though in the first case, it's only the
second case that keeps us from using `reference_get_peeled_oid()`. But
that second case only announces capabilities anyway, so we're not really

Both the "files" and "reftable" backend are able to store peeled values
for tags in the respective formats. This allows for a more efficient
lookup of the target object of such a tag without having to manually
peel via the object database.
The infrastructure to access these peeled object IDs is somewhat funky
though. When iterating through objects, we store a pointer reference to
the current iterator in a global variable. The callbacks invoked by that
iterator are then expected to call `peel_iterated_oid()`, which checks
whether the globally-stored iterator's current reference refers to the
one handed into that function. If so, we ask the iterator to peel the
object, otherwise we manually peel the object via the object database.
Depending on global state like this is somewhat weird and also quite
fragile.
Introduce a new `struct reference::peeled_oid` field that can be
populated by the reference backends. This field can be accessed via a
new function `reference_get_peeled_oid()` that either uses that value,
if set, or alternatively peels via the ODB. With this change we don't
have to rely on global state anymore, but make the peeled object ID
available to the callback functions directly.

With the introduction of the `struct ref_iterator::ref` field it now is
a whole lot easier to introduce new fields that become accessible to the
caller without having to adapt every single callsite. But there's a
downside: when a new field is introduced we always have to adapt all
backends to set that field.
This isn't something we can avoid in the general case: when the new
field is expected to be populated by all backends we of course cannot
avoid doing so. But new fields may be entirely optional, in which case
we'd still have such churn. And furthermore, it is very easy right now
to leak state from a previous iteration into the next iteration.
Address this issue by ensuring that the reference backends all fully
reset the field on every single iteration. This ensures that no state
from previous iterations can leak into the next one. And it ensures that
any newly introduced fields will be zeroed out by default.
Note that we don't have to explicitly adapt the "files" backend, as it
uses the `cache_ref_iterator` internally. Furthermore, other "wrapping"
iterators like for example the `prefix_ref_iterator` copy around the
whole reference, so these don't need to be adapted either.

The base iterator has a couple of fields that tracks the name, target,
object ID and flags for the current reference. Due to this design we
have to create a new `struct reference` whenever we want to hand over
that reference to the callback function, which is tedious and not very
efficient.
Convert the structure to instead contain a `struct reference` as member.
This member is expected to be populated by the implementations of the
iterator and is handed over to the callback directly.
While at it, simplify `should_pack_ref()` to take a `struct reference`

The `each_ref_fn` callback function type is used across our code base
for several different functions that iterate through reference. There's
a bunch of callbacks implementing this type, which makes any changes to
the callback signature extremely noisy. An example of the required churn
is e8207717f1 (refs: add referent to each_ref_fn, 2024-08-09): adding a
single argument required us to change 48 files.
It was already proposed back then [1] that we might want to introduce a
wrapper structure to alleviate the pain going forward. While this of
course requires the same kind of global refactoring as just introducing
a new parameter, it at least allows us to more change the callback type
afterwards by just extending the wrapper structure.
One counterargument to this refactoring is that it makes the structure
more opaque. While it is obvious which callsites need to be fixed up
when we change the function type, it's not obvious anymore once we use
a structure. That being said, we only have a handful of sites that
actually need to populate this wrapper structure: our ref backends,
"refs/iterator.c" as well as very few sites that invoke the iterator
callback functions directly.
Introduce this wrapper structure so that we can adapt the iterator
interfaces more readily.

The "--short" option of "git status" that meant output for humans
and "-z" option to show NUL delimited output format did not mix
