* 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.

`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.

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

they now run in parallel and each stays far inside the timeout, and a

* 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 now compares values with a tolerance.
- Rebase the jaeger v1 fixture on the current instant. It carries
ttl=7d with 2025 timestamps, so its rows were only readable as long as
they stayed in the memtable.

`/api/v1/label/__name__/values?match[]={pod="abc"}` dropped every matcher
other than `__name__` and returned all metrics in the schema. No error,
just the wrong list. Grafana's metrics browser sends this request, so
picking a label value there did nothing.
Selectors that only constrain `__name__` keep answering from table
metadata. A selector constraining an ordinary label now goes to the data:
scan each metric engine physical table for distinct `__table_id` in the
time range, map the ids back to metric names, then apply the selector's
own `__name__` matchers.

* fix(promql): read an absent label as the empty string
A matcher on a label the series does not carry only worked when the table
had no column for it at all. Where the column exists but is NULL on that
row -- the norm for logical metrics sharing a metric engine physical
table, which holds the union of their label columns -- three-valued logic
dropped the row, so `host!="host1"` and `host=""` missed every metric
without a host label.
Coalesce nullable string label columns to "" for matchers that accept the
empty string, rather than only for the OTLP temporality marker. Equality
matchers are untouched; they cannot match NULL either way.
This is the Prometheus compatibility fix#8970 deliberately kept out of
its own scope. The cost is visible in the regex sqlness plan: the
predicate becomes a CASE, so the scan loses its LastRow selector and
grows a FilterExec. Only negative and empty-accepting matchers pay it.

* refactor(prometheus): drop applicable_matchers, share the distinct scan
With the planner reading an absent label as empty, the frontend no longer
needs to pre-filter matchers per physical table. Removing that exposed a
second problem: a physical table that never took a column from a logical
table exposes no `__table_id`, and projecting it failed the whole request.
Skip those tables; the only thing that can miss is a metric with no labels.
Also pulls out the plan-build-execute-collect sequence the two label value
scans had in common.

* fix: match system schema names case-insensitively
Database names that arrive over a protocol (the MySQL handshake and
COM_INIT_DB, the Postgres startup parameter, the HTTP `db` parameter, the
gRPC dbname header) never reach the SQL parser, which is what lowercases
unquoted identifiers. Since #8062 stopped lowercasing them wholesale,
connecting to `INFORMATION_SCHEMA` in any spelling but the canonical one
fails with "Unknown database" -- including the `USE <db>` that a MySQL
client turns into COM_INIT_DB.
Fold only system schema names to their canonical spelling, so user schema
names keep the case they were created with. `is_reserved_schema_name` uses
the same match, otherwise a quoted `CREATE DATABASE "INFORMATION_SCHEMA"`
creates a schema shadowed by the system one.

* fix(pipeline): coalesce concurrent pipeline cache misses
The pipeline cache reads with a plain `moka::sync::Cache::get` and falls
through to a distributed query on a miss, so when the 10s TTL expires every
in-flight write request on a frontend issues its own scan of the single-region
`greptime_private.pipelines` table. Concurrent scans per expiry scale with
write QPS, and every frontend's burst lands on the same datanode. A user
running high-throughput ingestion through a pipeline saw that datanode
overloaded.
Switch to `moka::future::Cache::try_get_with` so concurrent misses on the same
key share one loader. This requires a single-key lookup, so cache entries are
now keyed by the requested schema rather than the schema the pipeline is stored
under; resolving a request to a stored schema stays in the loader, which is the
authoritative path and already handles the empty-schema and multi-schema cases.
A lookup for a schema not yet cached costs one extra read, now protected from
amplification by the coalescing it enables.
`remove_cache` previously only walked the compiled-pipeline cache, so an entry
populated by `get_pipeline_str` alone (the pipeline read API) survived deletion
until it expired. It now walks all three caches.
Also make the TTL configurable as `pipeline.cache_ttl`, default unchanged at
10s. The TTL is what propagates a pipeline change to other frontends, so
raising it trades staleness for fewer reads.

* fix(pipeline): restore cross-schema semantics broken by the new cache key
Keying cache entries by the requested schema dropped two behaviours that the
previous stored-schema key provided for free.
Creating a new version only wrote the creating request's schema, so another
schema on the same frontend kept serving its cached `latest` — an older
version — until the entry expired. Since the whole point of making the TTL
configurable is to let operators raise it, that window is not bounded by
anything useful. Creation now invalidates every schema's `latest` alias for
that name before priming the cache, leaving the version-pinned keys alone.
The failover cache lost its reach across schemas the same way: a global
pipeline (stored under the empty schema) loaded by schema A was cached under
`A`, so schema B using it for the first time while the pipeline table was down
missed and failed ingestion. The failover cache has no loader and so is not
subject to the single-key model of `try_get_with`; it keeps the stored-schema
key and the empty-schema-first resolution.

* refactor(pipeline): drop cache priming on create and fold the sweep helpers
Priming the cache on create saved one read on a low-frequency operation and
cost a concept: entries were written under the creating request's schema while
`PipelineContent.schema` said empty, so the two schemas in play disagreed.
Invalidating the `latest` aliases is required regardless — that is what makes
a new version visible to other schemas — so dropping the priming loses only
the saved read, which coalescing now protects anyway. `insert_and_compile` no
longer needs the caller's schema.
`remove_cache` and the create-time invalidation collapse into one
`invalidate(name, version)`; `None` sweeps only the `latest` aliases, which is
exactly what creation wants. That leaves `invalidate_by_suffixes` and
`cache_keys` with a single caller each, so both are inlined.
Drop the `PipelineOptions` humantime test: `load_config_test` loads both
example TOMLs, which now carry `cache_ttl = "10s"`, and would fail the same
way if the serde attribute were lost. The `toml` dev-dependency goes with it.
The two invalidation tests are now checked to be orthogonal: removing the
version suffix fails only the delete test, and sweeping just the compiled
cache fails both.

* fix(pipeline): keep failover populated across a create
The `latest` sweep on create clears the failover cache along with the loaded
ones, and after dropping the priming there was nothing writing it back. An
outage between the create and the first read-back left neither `latest` nor the
explicit version with anything to fall back on, failing ingestion — worse than
before, since the previous version's failover entry was swept too.
Creation now goes through `PipelineCache::on_pipeline_created`, which pairs the
sweep with a failover write of the new empty-schema definition. The two must
happen together, so they live behind one method rather than at the call site.
Also commit the Cargo.lock entry for the dropped `toml` dev-dependency, and
trim the comments added over the last few commits down to what the code does
not already say.
