jeremyhi 194bc2fb3c feat(log-store): add the object store WAL durable write path (#9320)
* feat(log-store): add the object store WAL durable write path

ObjectStoreLogStore can now write. append_batch admits entries into one
open batch and assigns object-sequence-major entry ids at admission. The
batch is sealed by size, by the flush interval, or before a region would
run past the position range, and sealed batches are uploaded with at most
four conditional creates in flight, started in sequence order. Created
objects are indexed in sequence order, and an append is acknowledged only
once its object is durable and indexed.

A transient create failure rolls back the failed batch and every later
batch unless a later object is already durable, in which case the store
poisons itself with a history-gap error. A conflicting object, an
encoding or catalog error, or taking the last representable sequence
poisons the store.

obsolete now goes through the actor and raises the sequence floor
together with the watermark, refusing with a retryable error while the
next sequence is not settled. stop drops the open batch and the batches
whose create has not started, and lets creates in flight finish.

Only the durable acknowledgement mode exists. A testing feature exposes
hooks to wait for admissions, seal the open batch, and hold or fail
creates.

* test(log-store): synchronize object store WAL write tests with the actor

Tests that assert nothing happened round-trip a command through the actor
instead of yielding the test task, the conflict test waits for the object
it expects, and the obsolete-behind-stop test holds the command channel
itself so the unanswered command is deterministic.

* fix(log-store): bound admitted WAL appends and never reuse a failed sequence

A create that reports an error may still have written its object, so the
sequences of failed batches are no longer handed out again: the next
batch keeps the sequence after the last sealed one and retries are
assigned new ids. A retry batched differently can no longer conflict
with that object. As the next sequence never moves back, the sequence
floor of obsolete only waits for an open batch that has handed out ids.

Appends now arrive on their own bounded channel, which the actor stops
reading while MAX_SEALED_BATCHES batches wait to become durable, so a
stalled object store holds callers back instead of growing the backlog,
while stop and obsolete are still handled.

* fix(log-store): reserve room for two seals before admitting a WAL append

One admission can seal the open batch before an append that would exhaust
its positions and then the append's own batch, so the actor takes an
append only while two more sealed batches fit under MAX_SEALED_BATCHES.

* feat(log-store): chain object store WAL objects and recover the latest chain

A conditional create can fail with an unknown outcome while its object is
stored, or still lands later, and Mito reuses the row sequences of a
failed append. Replaying such an object next to a later acknowledged one
can let the unacknowledged rows win after a restart.

Format version 2 gives every object header its writer's epoch, a link
to the object it extends (sequence and writer instance) and a header
CRC32, and allows objects without segments. Recovery replays only the
chain ending at the complete object with the largest epoch and sequence:
a link holds when its predecessor is present with the recorded writer
instance, or is missing below every present object. Objects off the
chain are orphans that are never replayed but keep their sequences.

Each open writes an empty object that starts an epoch above every
present object, linked to the recovered tip, before it accepts writes,
so a late object of an earlier instance never ends the chain. A start
object that meets an object of an earlier epoch moves to the next
sequence; one of an equal or later epoch fails the open.

* fix(log-store): break the WAL chain at every missing predecessor

Accepting a missing predecessor below every present object lets a late
object that lands below the chain change which links hold. Nothing
collects objects yet, so a missing predecessor now always breaks the
link, and recovery fails when objects are present but none completes a
chain.

* fix(log-store): keep the object store WAL format at version 1

The object store WAL has not been enabled anywhere, so no object in the

* refactor(log-store): link object store WAL objects by epoch

Only one store instance writes under an epoch, since every open starts an
epoch above every present object and a start object that meets the same
or a later epoch fails the open. The epoch therefore identifies the
instance, and the random writer instance id is dropped from the header.
A link now records the sequence and the epoch of the object it extends,
and holds when the predecessor carries that epoch. The header shrinks to
46 bytes, and the store logs its epoch when it opens.

* fix(log-store): fail an open whose start object is already present

Without a random writer instance, two opens that recover the same objects
encode byte-identical start objects, and a conditional create treats the
same bytes as its own retry. A start object that is already present
therefore fails the open with a retryable error instead of letting both
opens claim the epoch; the next open counts the object and starts a
later epoch.

Signed-off-by: jeremyhi <fengjiachun@gmail.com>

* fix(log-store): derive the WAL epoch from the claimed start sequence

Two opens can recover different listings when a late object lands across
a sequence gap between them, pick the same largest epoch plus one, and
both create their start objects under different sequences. The epoch of
an instance is now one above the sequence its start object claims, so a
successful create decides the epoch and no two instances share one. It
stays above every epoch recovery listed, and an object that carries an
epoch above the next sequence fails the open.

* fix(log-store): never run a held WAL create after the store is dropped

The create test hook ignored the closed hold channel, so a create parked
when the store was dropped could still run. It now returns without
creating. Drop the per-admission bookkeeping of issued entry ids, which
nothing reads, and move the parked I/O documentation to its helper.

Signed-off-by: jeremyhi <fengjiachun@gmail.com>

* test(log-store): cover a WAL start object stored with an unknown outcome

Add a fault-injection test in which the create of the start object
stores the object but reports an error: the open fails without moving
to another sequence, and the next open counts the stored object and
claims a later epoch. Rename the test helper that writes a whole object
from a given header to put_object_with_header, and drop a needless
clone.

Signed-off-by: jeremyhi <fengjiachun@gmail.com>

* test(log-store): make the held-create drop test deterministic

Keep the actor running while the store drops the hold sender, so the
parked create always completes on the closed channel instead of racing
the actor's exit. Drop a comment that restates epoch_of.

Ning Sun 20619273ee chore(toolchain): switch to stable Rust 1.96.1 and remove all nightly feature gates (#9303)
* chore(toolchain): switch to stable Rust 1.96.1 and remove all nightly feature gates

Move the workspace from the pinned nightly-2026-03-21 to stable
1.96.1 and drop all 23 '#![feature]' gates across 13 crates,
rewriting the still-unstable API usages with stable equivalents:

- try_blocks: closures / an async block (table, query, common-function, servers)
- duration_constructors: Duration::from_secs(n * 86400) / (n * 60)
- iterator_try_collect: collect::<Result<Vec<_>, _>>()
- box_patterns: as_deref() + matches! chains (sql)
- error_iter: error_chain_root() source-chain walker (common-error);
  sources() includes the error itself, so the walker never panics
- int_roundings: div_floor -> div_euclid (equal for positive divisors)
- iter_partition_in_place: stable sort_by_key partition helper (index)
- hash_set_entry: HashSet::insert bool / contains+insert
- trait_alias: lifetime-parameterized dyn FnOnce type aliases (puffin)
- string_from_utf8_lossy_owned: from_utf8_lossy(&v).into_owned()
- never_type: Infallible (common-recordbatch)
- debug_closure_helpers: closure-backed DebugFmt newtype (mito2)
- binary_heap_pop_if: peek().is_some_and() + pop()
- exclusive_wrapper: drop Exclusive; C: Send + Unpin already in bounds
- stmt_expr_attributes: stale gate, no usages

Also fix release-dev-builder-images.yaml, which parsed
rust-toolchain.toml with a date-only regex and would produce empty
image versions with a stable channel; it now extracts the full
channel token. Dev-builder images verified against stable 1.96.1
(image build, default-toolchain behavior, binstall/nextest, riscv64
and android targets, in-image cargo check).

Validated on 1.96.1: cargo check --workspace --all-targets, clippy
--workspace --all-targets --all-features -D warnings, cargo fmt
--check, and nextest on all 13 affected crates (4586 passed).

Part of #9289. Depends on #9298 (fuzz nightly quarantine) merging
first.

discord9 abedeb2bea fix(query): keep count_values generated label in enclosing expressions (#9223)
* fix(query): keep count_values generated label in enclosing expressions

`count_values("v", m)` projects the generated label as a real output
column, but did not register it in `ctx.tag_columns`. Enclosing
expressions (abs/round/+1/topk/label_replace/vector join) rebuild their
projection from `ctx.tag_columns` and silently drop the label.

Register the generated label in `ctx.tag_columns` after the projection,
and give it the same qualifier as other tag columns so qualified
references resolve. PromQL overwrites an input label with the same name,
so drop any existing tag with that name first to avoid duplicate column
ambiguity.

* fix(flow): keep count_values generated label as sink table primary key

FindGroupByFinalName::f_up only renamed a group key when the projection
aliased the key column directly. count_values now projects its generated
label as a unary UDF over the sampled column
(prom_float_to_string(value) AS label) while the aggregate still groups
by the raw column, so the name match failed and the sink table lost the
label from its PRIMARY KEY, demoting it to a DOUBLE value column.

Allow a projection above the aggregate to rename a group key by deriving
its output from a single group-key column (unary scalar function or cast
over that column only). Multi-column expressions, case, aggregates,
windows, subqueries and literals are still rejected so a computed column
cannot be mistaken for the group key.

* fix(query): group count_values by the formatted sample value

The numeric count_values branch grouped by the raw sample column and only
formatted the value into the generated label in the post-aggregate
projection. Two distinct raw values that collapse to one label text
(e.g. BIGINT 9007199254740992 and 9007199254740993, both 9007199254740992
in Float64) were split into two groups, each emitting the same label set
at one timestamp, violating Prometheus' unique-label-set-per-timestamp
invariant.

Return the formatted value expression (prom_float_to_string, with a
CAST to Float64 for non-Float64 inputs) as previous_field_expressions so
the aggregate groups by the same expression that produces the label,
mirroring the existing mixed float/native-histogram precedent.

* fix(flow): don't replace group key with derived unary expr

FindGroupByFinalName treated any unary expression of a single group
column (scalar fn, Cast, TryCast) as a rename of that group key and
swapped it in as the sink primary key. A derived expression such as
lower(host) is many-to-one, so distinct groups (HOST_A vs host_a) would
collapse to the same primary key and be silently deduplicated.

Narrow the matching to direct name-matched aliases of the actual group
expression only, and drop the derived-unary path (is_unary_expr_of_column)
and the allow_derived flag. count_values already groups by the formatted
expression name, so it is unaffected.

Add a regression asserting host survives and host_lc does not replace it
under both optimizer settings.

dennis zhuang d59725b04a test(sqlness): run environments concurrently and drop redundant restarts and sleeps (#9333)
* test(sqlness): run environments concurrently with external backends

The runner forced both environment and instance parallelism to 1 whenever
etcd/PG/MySQL or an external Kafka was set up, so the standalone and
distributed environments ran one after the other.

Only distributed uses the kv backend, and the two environments use
different Kafka topic prefixes, so they can run at the same time. Keep one
instance per environment, since instances would share the metadata table
and Kafka topics. Runs with a runner-managed Kafka, an external server, a
test filter, or `-j 1` stay fully serial.

- alter_table_options, skip_wal: share restarts between independent tables.
- session_skip_wal, copy_skip_wal: check every case after a single restart.
  Tables copied or inserted with skip_wal = true first get a WAL row that is
  truncated, so the check that truncated WAL entries are not replayed stays.

dennis zhuang 88197f4019 fix(promql): derive vector matching result labels and reject ambiguous matchings (#9306)
* fix(promql): derive vector matching result labels and reject ambiguous matchings

A vector-vector binary operation projected one operand's whole tag set and
inner-joined without any cardinality check, so `on()`/`ignoring()` did not
reduce the result labels, `group_left`/`group_right` changed nothing, and a
non-unique match group produced a cross product that PromQL cannot represent.

Result labels now follow Prometheus `resultMetric`: `on(...)` keeps the
matching labels, `ignoring(...)` drops them, and a group modifier keeps the
many side's labels plus the `group_x(...)` labels taken from the one side.
A label the one side does not carry is deleted from the result. The reduced
label set no longer identifies the operand series, so `__tsid` is dropped
from the context on this path.

Cardinality is enforced with a `count(1) OVER (PARTITION BY match keys, ts)`
window and a scalar UDF that fails the query on a repeated group: on the one
side before the join, and on the result labels after it, matching where
Prometheus raises each of its three errors. Series are unique by their whole
tag set, so the window is only planted when the match keys drop a tag; plain
arithmetic and `on(<all tags>)` plan exactly as before.

Closes #9207, closes #9208, closes #9209.

* perf(promql): keep __tsid when the result labels are an operand's whole tag set

Deriving the result labels dropped `__tsid` from the context unconditionally,
so an enclosing operation fell back to joining on the tag columns even where
the column still identified the result series.

Keep it when every result label comes from one operand and covers that
operand's whole tag set: no other operand value reaches the labels, and the
matching gives each of its rows a single partner, so its `__tsid` is still one
per result series. That is the common `on(<all tags>)` and bare `group_left`
shape; a matching that actually drops a tag still clears it.

The column is re-qualified as the result's own, which is how the enclosing
expression and the context look it up.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* fix(promql): keep the match group count column unambiguous

The cardinality check aliased its row count to a fixed `__promql_match_group_count`.
An operand carrying a label of that name made the window output two fields with
the same name, and planning failed with "Schema contains qualified field name
collide_right.__promql_match_group_count and unqualified field name
__promql_match_group_count which would be ambiguous".

Pick a name the operand does not already have, the way the `or` operator
allocates its match key columns.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* test(promql): cover a match group spread over several regions

The cardinality check runs above the merge of the region scans, so it counts a
match group globally. Nothing pinned that: every table in these cases holds a
single region, and a check evaluated per region would pass them all.

Partition the operand on a column outside the match keys, which puts the two
series of one match group in different regions, and assert both the pre-join
and the post-join check still reject it. The case runs in the distributed
environment too, where the regions sit on different datanodes.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* fix(promql): group an outer aggregate on the labels the operand kept

`by`/`without` planning topped up a missing grouping column by walking down to
the table scan and re-projecting it. That is right for a column the scan pruned
for efficiency, but the labels a matching modifier deletes are also absent from
the operand's output, and they were restored the same way:

  sum without(host) (a / on(host) b)

`on(host)` leaves the operand with `host` alone, so the sum covers everything
and Prometheus answers `{} 10`. Instead `device` came back from the scan under
`a` and split the result into `{device="d1"} 5` and `{device="d2"} 5`. Same for
`sum by(device)` of that operand, which has no `device` to group on at all.

Take the grouping labels from the operand's own label set rather than from the
row keys of the scan beneath it. A label pruned from the plan is still in that
set and still gets restored; a label the operand dropped is not.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* refactor(promql): drop the unreachable aggregation tag top-up

`by`/`without` planning could restore a grouping column that the plan no longer
carried by rewriting the scan underneath it. Once the grouping labels come from
the operand's own label set, there is nothing left for it to restore: a scan
projects every label of `ctx.tag_columns` (`scan_tag_columns` only ever adds
matcher columns to that set), so a label in the set is always in the schema.

Stubbing the rewriter to a no-op passed the whole sqlness suite, in both the
standalone and the distributed environment.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* test(promql): drop cases that guarded the removed tag top-up

Three plain selector aggregates were there to show that restoring a pruned
grouping column still worked. With the restore gone they only repeat what the
aggregate cases already cover. Also fix a comment that still said the metric
engine scan prunes tag columns: it projects every label of the operand.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* docs(promql): note the duplicate a propagated matcher hides

A matcher copied onto the one-side operand removes groups without a partner
before the cardinality check sees them, so a duplicate in such a group is not
reported. Prometheus checks every group of the one side and fails the query.

* chore(deps): replace cargo-udeps with cargo-shear for unused dependency checks

cargo-udeps requires a nightly toolchain and its pinned version (0.1.61)
no longer detects unused dependencies against current cargo internals —
unused deps have landed on main undetected (e.g. humantime in
common-frontend since #6689). cargo-shear is a standalone static analyzer
that runs on any toolchain.

- Swap 'make check-udeps' / 'make fix-udeps' recipes to 'cargo shear' /
  'cargo shear --fix' and retire scripts/fix-udeps.py
- CI: install cargo-shear in the check-udeps job; drop the build cache
  and protoc steps (cargo-shear never compiles)
- Remove ~150 unused dependency declarations found by cargo-shear, move
  misplaced deps to the correct sections, drop orphaned
  [workspace.dependencies] entries (arrow-cast, rustc-hash)
- Add [package.metadata.cargo-shear] ignored entries with explanations
  for dependencies that are structurally required despite no textual
  reference: sqlparser (required by sqlparser_derive expansions in
  datatypes, common-query), common-error (required by common-macro's
  stack_trace_debug expansions in session, tests-fuzz), k8s-openapi
  (feature-pinning for the transitive kube dependency in tests-fuzz),
  tikv-jemalloc-sys (link-only, enables jemalloc profiling features in
  common-mem-prof), protobuf (required by build.rs-generated bindings in
  log-store)
- Drop the obsolete [package.metadata.cargo-udeps.ignore] sections

* ci: create docs follow-up issue on PR merge instead of on label (#9237)

* ci: create docs follow-up issue on PR merge instead of on label

The docbot workflow previously created a docs-repo issue as soon as the
'docs-required' condition was detected (PR opened/edited with the docs
checkbox ticked), even if the PR was never merged.

Now the workflow also triggers on PR 'closed':
- opened/edited: only manage the docs-required/docs-not-required labels
- closed: create the docs issue only when the PR was actually merged and
  carries the docs-required label

This also lets maintainers control issue creation by manually adding or
removing the docs-required label before merging.

Signed-off-by: Ning Sun <sunning@greptime.com>

* fix: address review comments on docs issue creation timing

- Only touch docs labels when the docs checkbox state actually changed
  in an edit. Previously, editing any other part of the PR body while
  the checkbox stayed checked removed the docs-required label, silently
  dropping the docs follow-up now that issue creation happens at merge.
  Unchanged checkbox now leaves labels untouched, which also preserves
  manual label overrides.
- Do not trust the closed event's stale label snapshot at merge time:
  re-read the live PR via the API and create the docs issue if the
  docs-required label is present OR the checkbox is ticked in the
  current body.
- Make the workflow concurrency group action-aware so a merge run does
  not cancel an in-flight label update from an edit run.

Signed-off-by: Ning Sun <sunning@greptime.com>

* fix: make docs-required label the single source of truth at merge

The label-OR-checkbox merge condition could not distinguish an
intentional opt-out from an unfinished label update: removing
docs-required while the checkbox stayed checked still produced an
issue, and unchecking the box could still produce one if the merge
read the stale label before the edit run removed it.

At merge time, wait for any pending docbot runs on the PR head SHA to
finish their label updates (bounded to 5 minutes), then decide solely
by the live docs-required label. Adds actions: read permission for
listing workflow runs.

* refactor(promql): spell out the shapes a filter may cross

`preserves_filter` ended in `_ => true`, which was only sound because
`selector_matchers` independently rejects label rewriting, `count_values`,
subqueries and non-rollup calls on the same operand. Loosening the latter
alone would have silently pushed a matcher below a label rewrite. List the
shapes that carry a scan filter instead and default to `false`.

Cite #9207 for the result labels the grouped cases record: the join
projects the right operand's tag set, so `zone` is missing wherever the
right side aggregates it away.

No behavior change.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* test(promql): assert the new pushdowns reach the scan

The grouped-join unit tests feed tag columns by hand and the SQLness case
only checks results, which are identical whether or not the rewrite fires.
Nothing would have failed if scalar arithmetic, ranking or grouped
matching stopped propagating. Assert through the planner that the matcher
reaches both scans, with a global topk one-side as the counter-example.

Also state that the duplicate-one-side cases record a cross product
Prometheus rejects (#9209), so the baseline is not read as intended
semantics.

Split each case into its own test. Cases were already independent, so
they now run in parallel and each stays far inside the timeout, and a
failure points at one encoding instead of four.

dennis zhuang f3eb8e6c72 test: cut integration test time and make the storage matrix meaningful (#9308)
* test: cut integration test time and make the storage matrix meaningful

tests-integration is ~85% of workspace test CPU, and 81% of that is the
S3/S3WithCache variants of the HTTP and gRPC suites. Those suites do not
touch the object store: of the 70 matrix HTTP tests only one flushed and
read back an SST, so the matrix was paying real AWS round trips to
re-prove protocol parsing.

- Point the PR CI object-store matrix at the MinIO already started by
  tests-integration/fixtures. Three GT_S3_* consumers did not read
  GT_S3_ENDPOINT_URL and would have hit real AWS with MinIO credentials;
  they now do.
- Add a nightly Linux job against real AWS S3, and pass GT_S3_* into the
  release integration-test container. The release previously ran every
  remote-backend case as a skip and only exercised the file backend.
- Give each S3WithCache test its own read cache directory. They shared
  /tmp/greptimedb_cache, which the datanode wipes on startup, so a
  starting test deleted the read cache of a running one.
- Add flush -> read-back assertions to the tests whose columns have a
  non-trivial SST representation: JSON/JSON2 columns, native histograms,
  metric-engine logical tables, and tables carrying fulltext or skipping
  indexes whose puffin files only exist after a flush.
- Move eight tests that create no table out of the storage matrix.
- Make the event recorder flush interval a constructor parameter and
  shorten it in the event tests, which otherwise wait a 5s window per DDL
  they assert on. It is skipped by serde and never reaches config files.
- Drop duplicates: test_grpc_zstd_compression was a verbatim copy of
  test_grpc_message_size_ok and is now rewritten to assert the negotiated
  grpc-encoding; test_execute_copy_to_{s3,oss,gcs,azblob} were strict
  prefixes of their copy_from siblings; two standalone/distributed event
  test pairs shared one assertion body.
- Fix and un-ignore stddev_by_label. stddev_pop merges partial aggregates
  in a parallelism-dependent order, so its last digits are unstable; the

* test: address review — wire nightly real-S3 job into check-status, keep the short event interval

The nightly `check-status` job did not depend on the new real-S3 job, so a
failure there would not have reached the status or Slack notification.

In database_ddl_event the short interval was set by a first
`with_event_recorder_options` call and then overwritten by the pre-existing
one, which carries `..Default::default()`. Merged into a single call.

Ning Sun edc81c2355 ci: update cargo fuzz command to use nightly toolchain explicitly (#9298)
* ci: update cargo fuzz command to use nightly toolchain explicitly

* ci: honor RUSTUP_TOOLCHAIN pin in fuzz orchestration script

An explicit `+toolchain` argument overrides the RUSTUP_TOOLCHAIN env var
in rustup precedence, so the hard-coded `cargo +nightly` in
run-fuzz-targets.sh bypassed the pinned FUZZ_RUST_TOOLCHAIN
(nightly-2026-03-21) configured in the workflow.

- Invoke `cargo +"${RUSTUP_TOOLCHAIN:-nightly}" fuzz run` in the script
  so CI uses the pinned toolchain and local runs fall back to the
  floating nightly
- Pass RUSTUP_TOOLCHAIN through to all four fuzz-test action invocations,
  covering the no-prebuilt-binaries path and making the reproduce command
  in the summary print the exact pinned toolchain
- Add test_rustup_toolchain_env_is_honored covering the pinned-env
  scenario for both the cargo invocation args and the summary text

Addresses #9298 (review).

* fix(ci): build tests-integration lib with meta-srv/mock

tests-integration's lib code (src/cluster.rs) uses meta_srv::mocks, but
the dependency carrying the mock feature sits in [dev-dependencies].
Builds that only touch the lib, such as the apidoc job's cargo doc
--workspace, resolve meta-srv without mock and fail with E0432.
--all-targets builds unify dev-dependency features, which is why check,
clippy and nextest stayed green.

Move the mock-enabled meta-srv entry back to [dependencies]. The other
testing features moved out in #9072 are not needed by the lib and stay
in [dev-dependencies].

* test(repartition): split per-case repartition tests

test_repartition_metric ran four format/primary-key-encoding cases in a
single test function, and test_repartition_mito ran two format cases.
Each case builds its own 3-datanode cluster and runs a full repartition
plus GC cycle, so on S3 the metric test took 165-178s against the 180s
nextest terminate-after. Merge queue runs failed on it at random.

Split each case into its own test. Cases were already independent, so
they now run in parallel and each stays far inside the timeout, and a
failure points at one encoding instead of four.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* refactor(promql): spell out the shapes a filter may cross

`preserves_filter` ended in `_ => true`, which was only sound because
`selector_matchers` independently rejects label rewriting, `count_values`,
subqueries and non-rollup calls on the same operand. Loosening the latter
alone would have silently pushed a matcher below a label rewrite. List the
shapes that carry a scan filter instead and default to `false`.

Cite #9207 for the result labels the grouped cases record: the join
projects the right operand's tag set, so `zone` is missing wherever the
right side aggregates it away.

No behavior change.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* test(promql): assert the new pushdowns reach the scan

The grouped-join unit tests feed tag columns by hand and the SQLness case
only checks results, which are identical whether or not the rewrite fires.
Nothing would have failed if scalar arithmetic, ranking or grouped
matching stopped propagating. Assert through the planner that the matcher
reaches both scans, with a global topk one-side as the counter-example.

Also state that the duplicate-one-side cases record a cross product
Prometheus rejects (#9209), so the baseline is not read as intended
semantics.

Ning Sun 2388257c35 ci: create docs follow-up issue on PR merge instead of on label (#9237)
* ci: create docs follow-up issue on PR merge instead of on label

The docbot workflow previously created a docs-repo issue as soon as the
'docs-required' condition was detected (PR opened/edited with the docs
checkbox ticked), even if the PR was never merged.

Now the workflow also triggers on PR 'closed':
- opened/edited: only manage the docs-required/docs-not-required labels
- closed: create the docs issue only when the PR was actually merged and
  carries the docs-required label

This also lets maintainers control issue creation by manually adding or
removing the docs-required label before merging.

Signed-off-by: Ning Sun <sunning@greptime.com>

* fix: address review comments on docs issue creation timing

- Only touch docs labels when the docs checkbox state actually changed
  in an edit. Previously, editing any other part of the PR body while
  the checkbox stayed checked removed the docs-required label, silently
  dropping the docs follow-up now that issue creation happens at merge.
  Unchanged checkbox now leaves labels untouched, which also preserves
  manual label overrides.
- Do not trust the closed event's stale label snapshot at merge time:
  re-read the live PR via the API and create the docs issue if the
  docs-required label is present OR the checkbox is ticked in the
  current body.
- Make the workflow concurrency group action-aware so a merge run does
  not cancel an in-flight label update from an edit run.

Signed-off-by: Ning Sun <sunning@greptime.com>

* fix: make docs-required label the single source of truth at merge

The label-OR-checkbox merge condition could not distinguish an
intentional opt-out from an unfinished label update: removing
docs-required while the checkbox stayed checked still produced an
issue, and unchecking the box could still produce one if the merge
read the stale label before the edit run removed it.

At merge time, wait for any pending docbot runs on the PR head SHA to
finish their label updates (bounded to 5 minutes), then decide solely
by the live docs-required label. Adds actions: read permission for
listing workflow runs.
