Certain reference backends {packed, reftable}, have the ability to also
store the peeled object ID for a reference pointing to a tag object.
This has the added benefit that during retrieval of such references, we
also obtain the peeled object ID without having to use the ODB.
To provide this functionality, each backend independently calls the ODB
to obtain the peeled OID. To move this functionality to the generic
layer, there must be support infrastructure to pass in a peeled OID for
reference updates.
Add a `peeled` field to the `ref_update` structure and modify
`ref_transaction_add_update()` to receive and copy this object ID to the
`ref_update` structure. Finally, modify `ref_transaction_update()` to
peel tag objects and pass the peeled OID to
`ref_transaction_add_update()`.
Update all callers of these functions with the new function parameters.
Callers which only add reflog updates, need to only pass in NULL, since
for reflogs, we don't store peeled OIDs. Reference deletions also only
need to pass in NULL. For others, pass along the peeled OID if
available.
In a following commit, we'll modify the backends to use this peeled OID
instead of parsing it themselves.

Regular reference updates made via reference transactions validate that
the provided object ID exists in the object database, which is done by
calling 'parse_object()'. This check is done independently by the
backends which leads to duplicated logic.
Let's move this to the generic layer, ensuring the backends only have to
care about reference storage and not about validation of the object IDs.
With this also remove the 'REF_TRANSACTION_ERROR_INVALID_NEW_VALUE'
error type as its no longer used.
Since we don't iterate over individual references in
`ref_transaction_prepare()`, we add this check to
`ref_transaction_update()`. This means that the validation is done as
soon as an update is queued, without needing to prepare the
transaction. It can be argued that this is more ideal, since this
validation has no dependency on the reference transaction being
prepared.
It must be noted that the change in behavior means that this error
cannot be ignored even with usage of batched updates, since this happens
when the update is being added to the transaction. But since the caller
gets specific error codes, they can either abort the transaction or
continue adding other updates to the transaction.
Modify 'builtin/receive-pack.c' to now capture the error type so that
the error propagated to the client stays the same. Also remove two of
the tests which validates batch-updates with invalid new_oid.

When using git-update-ref(1) with the '--batch-updates' flag, updates
rejected by the reference backend are displayed to the user while other
updates are applied. This only applies during the commit phase of the
transaction.
In the following commits, we'll also extend `ref_transaction_update()`
to reject updates before a transaction is prepared/committed. In
preparation, modify the code in update-ref to also handle non-generic
rejections from `ref_transaction_update()`. This involves propagating
information to each of the commands on whether updates are allowed to be
rejected, and also checking for rejections and only dying for generic
failures.
Errors encountered during updates will be shown to the user immediately
unlike other errors encountered only when the transaction is
prepared/committed. As the verification of object IDs and peeled tag
objects will move into `ref_transaction_update()` in the following
commit, this means that those errors will be shown to the user before
other errors, this changes the order of errors, but the functionality
remains the same.

The `ref_transaction_update()` function is used to add updates to a
given reference transactions. In the following commit, we'll add more
validation to this function. As such, it would be beneficial if the
function returns specific error types, so callers can differentiate
between different errors.
To facilitate this, return `enum ref_transaction_error` from the
function and covert the existing '-1' returns to
'REF_TRANSACTION_ERROR_GENERIC'. Since this retains the existing
behavior, no changes are made to any of the callers but this sets the
necessary infrastructure for introduction of other errors.

The reference backends need to know when to create reflog entries, this
is dictated by the 'core.logallrefupdates' config. Instead of relying on
the backends to call `repo_settings_get_log_all_ref_updates()` to obtain
this config value, let's do this in the generic layer and pass down the
value to the backends.

Reference backends are initiated via the `init()` function. When
initiating the function, the backend is also provided flags which denote
the access levels of the initiator. Create a new structure
`ref_store_init_options` to house such options and move the access flags
to this structure.
This allows easier extension of providing further options to the
backends. In the following commit, we'll also provide config around
reflog creation to the backends via the same structure.

As writing version 2 MIDX files by default breaks older versions of
Git and its reimplementations, use V2 only when necessary.
* jk/midx-write-v1-by-default:
MIDX: revert the default version to v1
We introduced midx version 2 in b2ec8e90c2 (midx: do not require packs
to be sorted in lexicographic order, 2026-02-24) and now write it by
default. The rationale was that older versions should ignore the v2 midx
and fall back to using the packs (just like we do for other midx
errors). Unfortunately this is not the case, as we have a hard die()
when we see an unknown midx version.
As a result, writing a midx with Git 2.54-rc2 puts the repository into a
state that is unusable with Git 2.53. And this midx write may happen
behind the scenes as part of normal operations, like fetch.
Let's switch back to writing v1 by default to avoid regressing the case
where multiple versions of Git are used on the same repository.
There is one gotcha, though: the v2 format is required for some new
features, like midx compaction, and running "git multi-pack-index
compact" will complain when asked to write a v1 index. The user must set
midx.version to "2" to make the feature work.
So instead of always using v1, we'll base the default on whether the
requested feature requires v2. That does mean that running midx
compaction will create a repository that can't be read by older versions
of Git. But we never do that by default; only people experimenting with
the new feature will be affected.
We have to adjust the test expectation in t5319, since it will now
generate v1 files. And our "auto-select v2" is covered by the tests in
t5335, which continue to check that compaction works without having to
set midx.version manually (and also explicitly check that asking for v1
with compaction reports the problem).

The glossary entry is a list of terms and their definitions, so
multi-paragraph definitions need "+" continuation lines to indicate
that they are part of a single entry.
When an entry contains a sub-list (say, a bulleted list), the final "+"
may become ambiguous: is it connecting the next paragraph to the final
entry of the sub-list, or to the original list of definition paragraphs?
Asciidoc generally connects it to the former, even when we mean the
latter, and you end up with the next paragraph indented incorrectly,
like this:
glob
...defines glob...
Two consecutive asterisks ("**") in patterns matched
against full pathname may have special meaning:
- ...some special meaning of **...
- ...another special meaning of **...
- Other consecutive asterisks are considered invalid.
Glob magic is incompatible with literal magic.
That final "Glob magic is incompatible" paragraph is in the wrong spot.
It should be at the same level as "Two consecutive asterisks", as it is
not part of the final "Other consecutive asterisks" bullet point.
The same problem appears in several other spots in the glossary.
Usually we'd fix this by using "--" markers, which put the sub-list into
its own block. But there's a catch: in some of these spots we are
already in an open block, and nesting open blocks is a problem. It seems
to work for me using Asciidoc 10.2.1, but Asciidoctor 2.0.26 makes a
mess of it (our intent to open a new block seems to close the old one).
Fortunately there's a work-around: when using a "+" list-continuation,
the number of empty lines above the continuation indicates which level
of parent list to continue. So by adding an empty line after our
unordered list (before the "+"), we should be able to continue the
definition list item.
But asciidoc being asciidoc, of course that is not the end of the story.
That technique works fine for the "glob" and "attr" lists in this patch,
but under the "refs" item it works for only 1 of the 2 lists! I can't
figure out why, and this may be an asciidoctor bug. But we can work
around it by using "--" open-block markers here, since we're not
already in an open block.
So using the extra blank line for the first two instances, and "--"
markers for the second two, this patch produces identical output from
"doc-diff HEAD^ HEAD" for both --asciidoctor and --asciidoc modes.

GitHub Actions started complaining about use of Node.js 20 and I was
wondering why only one job uses actions/checkout@v4, while everybody
else already uses actions/checkout@v5.
It turns out that it is caused by a semantic mismerge between
e75cd059 (ci: check formatting of our Rust code, 2025-10-15) that
added a new use of actions/checkout@v4 that happened very close to
another change 63541ed9 (build(deps): bump actions/checkout from 4
to 5, 2025-10-16) that updated all uses of actions/checkout@v4 to
use vactions/checkout@v5.

I claimed in 3c18135b (doc: am: say that --message-id adds a trailer,
2026-02-09) that `git am --message-id` adds a Git trailer. But that
isn’t the case; for the case of a commit message with a subject, body,
and no trailer block:
<subject>
<paragrah>
It just appends the line right after `paragraph`:
<subject>
<paragraph>
Message-ID: <message-id_trailer.323@msgid.xyz>
It does work for two other cases though, namely subject-only and with an
existing trailer block.
This is at best an inconsistency and arguably a bug, but we’re at the
trailing end of the release cycle now. So reverting the doc is safer
than making msg-id act as a trailer, for now.
