* 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.

* perf(promql): check matcher safety on the receiving operand
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.

* 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.

* 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

- Added methods `input_file_size` and `output_file_size` to `MergeOutput` in `compactor.rs` to streamline file size calculations.
- Updated `Compactor` implementation to use these methods for metrics tracking.
- Modified `Ranged` trait logic in `run.rs` to improve range comparison.
- Enhanced test cases in `run.rs` to reflect changes in compaction logic.
- **Metrics Enhancements**:
- Changed `COMPACTION_INPUT_BYTES` and `COMPACTION_OUTPUT_BYTES` from histograms to counters in `metrics.rs` for better performance tracking.
- **Debugging and Logging**:
- Added detailed logging for compaction pick results in `twcs.rs`.
- Implemented custom `Debug` trait for `FileMeta` in `file.rs` to improve debugging output.
- **Testing Enhancements**:
- Added new test `test_compaction_overlapping_files` in `compaction_test.rs` to verify compaction behavior with overlapping files.
- Updated `merge_mode_test.rs` to reflect changes in file handling during scans.

### Update `FileHandle` Debug Implementation
- **Refactor Debug Output**: Simplified the `fmt::Debug` implementation for `FileHandle` in `src/mito2/src/sst/file.rs` by consolidating multiple fields into a single `meta` field using `meta_ref()`.
- **Atomic Operations**: Updated the `deleted` field to use atomic loading with `Ordering::Relaxed`.

* feat/revise-compaction-picker:
**Update compaction logic and default options**
- **`twcs.rs`**: Enhanced logging for compaction pick results by improving the formatting for better readability.
- **`options.rs`**: Modified the default `max_output_file_size` in `TwcsOptions` from 2GB to 512MB to optimize file handling and performance.
* feat/revise-compaction-picker:
Refactor `find_overlapping_items` to use an external result vector
- Updated `find_overlapping_items` in `src/mito2/src/compaction/run.rs` to accept a mutable result vector instead of returning a new vector, improving memory efficiency.
- Modified benchmarks in `src/mito2/benches/bench_compaction_picker.rs` to accommodate the new function signature.
- Adjusted tests in `src/mito2/src/compaction/run.rs` to use the updated function signature, ensuring correct functionality with the new approach.
* feat/revise-compaction-picker:
Improve file merging logic in `run.rs`
- Refactor the loop logic in `merge_seq_files` to simplify the iteration over file groups.
- Adjust the range for `end_idx` to include the endpoint, allowing for more flexible group selection.
- Remove the condition that skips groups with only one file, enabling more comprehensive processing of file sequences.
* feat/revise-compaction-picker:
Enhance `find_overlapping_items` with `SortedRun` and Update Tests
- Refactor `find_overlapping_items` in `src/mito2/src/compaction/run.rs` to utilize the `SortedRun` struct for improved efficiency and clarity.
- Introduce a `sorted` flag in `SortedRun` to optimize sorting operations.
- Update test cases in `src/mito2/benches/bench_compaction_picker.rs` to accommodate changes in `find_overlapping_items` by using `SortedRun`.
- Add `From<Vec<T>>` implementation for `SortedRun` to facilitate easy conversion from vectors.
* feat/revise-compaction-picker:
**Enhancements in `compaction/run.rs`:**
- Added `ReadableSize` import to handle size calculations.
- Modified the logic in `merge_seq_files` to clamp the calculated target size to a maximum of 2GB when `max_file_size` is not provided.
* feat/revise-compaction-picker: Add Default Max Output Size Constant for Compaction
Introduce DEFAULT_MAX_OUTPUT_SIZE constant to define the default maximum compaction output file size as 2GB. Refactor the merge_seq_files function to utilize this constant, ensuring consistent and maintainable code for handling file size limits during compaction.
