* perf(promql): rescan windows that barely overlap
Reusing candidates loses to a plain scan when consecutive windows overlap
little: the deque bookkeeping then costs more than the rescan it replaces.
A local Criterion run on 4096 samples at width 240 / step 240 measured
10.79 -> 22.14 us for min and 12.83 -> 19.85 us for max.
Pick the evaluator once per batch from the first two windows. RangeManipulate
emits one window length and one step per batch, so that sample decides for all
of them, and both evaluators return identical bits, so a wrong pick costs time
only. Batches that do not qualify fold each window on its own.
Move the incremental state into SlidingExtrema so tests can drive it directly:
the exhaustive four-sample differential test cannot reach it through a UDF
call, because such a batch never qualifies for reuse.

* fix(promql): select the extrema evaluator from batch averages
Reading the window shape off the first two windows misreads the batch.
RangeManipulate starts a series at max(query start, first aligned sample),
so a series that begins inside the query range gets a first window covering
roughly one step, and a window covering no sample at all is emitted as
(0, 0). Either one closed the gate for the whole batch, including the
one-hour window at a 15s step that candidate reuse was written for.
Compare the batch averages instead: at least 32 samples per window, and a
step advancing at most a quarter of that. Uniform batches select exactly as
before, so the thresholds keep the meaning they were measured with.
The 32-sample rule had also moved most of the benchmark and query-regression
shapes onto the rescan, including the case built to measure reset and
rebuild. Widen those windows to 40 samples, add a step at the selection
boundary, and add an end-to-end case with 40-sample windows advancing 5.
Signed-off-by: Dennis Zhuang <xzhuang@greptime.com>
* fix(promql): ignore empty windows when measuring batch advance
The advance was read from the first and last window offsets, but a window
covering no sample is emitted as (0, 0). A query whose last evaluation lands
exactly one window past the last sample ends on such a window, and its zero
offset made a batch of disjoint windows look like one that never moved, which
selected the evaluator built for overlap. Results stayed correct; the cost was
deque bookkeeping on the shape the scan fallback exists for.
Take the offset span over the windows that cover a sample. Empty windows stay
in the window count, where they only make both conditions stricter.

Signed-off-by: dhruvxvaishnav <dhruvvaishnav687@gmail.com>
* test: regenerate skip_wal sqlness result
The previous commit changed tests/cases/standalone/common/skip_wal.sql without
regenerating the matching .result, so every Sqlness suite failed on the
mismatch. tests/cases/distributed/common is a symlink to standalone/common, so
the single stale file accounted for all five failing variants.
Regenerated from a real run. The recorded output now covers the cases the .sql
added:
* A table created with skip_wal = 'true' has no real WAL provider, so enabling
WAL is refused with Unsupported rather than the previous InvalidArguments.
* A RaftEngine-backed table accepts the true -> false transition, and repeating
it is a no-op.
* SHOW CREATE TABLE reports skip_wal = 'false' after the transition, including
after a restart.
* A row written while WAL was skipped is absent after restart, while a row
written after WAL was restored survives.
Verified locally with nothing else running on the machine: sqlness skip_wal
passes in both the standalone and distributed environments, and the regenerated
file is byte-identical to the output of an independent earlier run.

* fix(mysql): strip leading comments before the federated statement filter
JDBC clients prefix every statement with a comment. DataGrip sends
`/* ApplicationName=DataGrip <version> */` in front of each one, and every
pattern in the federated filter is anchored with `^`, so the prefix makes all
of them miss.
Two failures follow. `SET TRANSACTION READ WRITE` reaches the SQL parser and is
rejected. Worse, the DBeaver-specific entries such as
`^(/\* ApplicationName=(.*)SELECT @@(.*))` do match DataGrip's prefix, so
`SELECT @@GLOBAL.event_scheduler` and `SHOW VARIABLES LIKE ...` are absorbed
into a zero-column output, which the MySQL writer sends as an OK packet. The
JDBC driver reports that the statement returned no cursor.
Strip leading whitespace and comments before matching, and drop the
ApplicationName-specific entries the stripping makes redundant. The three that
had no unprefixed counterpart (`SHOW PLUGINS`, `SHOW ENGINES`, `SHOW @@...`)
keep their behaviour as plain patterns.
Also covers gaps found while probing the same path:
- `BEGIN` is absorbed like `START TRANSACTION`/`COMMIT`/`ROLLBACK`.
- `SHOW [GLOBAL|SESSION|LOCAL] VARIABLES|STATUS` parses; the scope is ignored
because GreptimeDB keeps no global/session split.
- `USER()`, `CURRENT_USER()`, `SYSTEM_USER()` and `SCHEMA()` are registered.

* fix(mysql): keep executable comments, reject multi-statement absorption
Review follow-up on the comment stripping, plus the remaining MySQL
compatibility gaps from #9155.
`/*!...*/` is an executable comment: mysqldump emits its initialization as
`/*!40101 SET NAMES ... */`, and the patterns match those verbatim. Stripping
it left an empty statement, so nothing matched and the original SQL reached the
parser, which rejects `SetNames` and `MultipleAssignments`. Leave executable
comments in place.
Absorbing a request also has to stop at a statement boundary, because every
pattern ends in `(.*)`. `BEGIN; INSERT INTO t VALUES (1)` used to fail on the
unsupported `BEGIN`; once `BEGIN` became absorbable the whole request would
report success and write nothing. A request is now scanned for a second
statement and handed to the query engine if it has one. The scan skips plain
comments and string literals so a `;` inside either is not a boundary, and
treats a `/*!...*/` that is not the request itself as a statement, since it
carries SQL.
`check()` now dispatches on the leading statement keyword, so INSERT, UPDATE,
CREATE and ordinary SELECTs run no regex at all — this replaces the narrower
hand-rolled INSERT shortcut. The statement scan runs only for a request the
patterns already matched, which is always a short one.
New compatibility surface:
- `SELECT CURRENT_USER|SESSION_USER|SYSTEM_USER|USER` without parentheses, and
`SELECT @var`, are answered here rather than in the parser. Both are anchored
to the whole statement, so `SELECT user FROM t` still reads the column.
- `information_schema.plugins`, `user_privileges` and `processlist` are
registered as empty tables, like the other MySQL-shape tables around them.
Sessions are reported through `information_schema.process_list` and
`SHOW PROCESSLIST`; `processlist` carries the column shape only.

* perf(servers): group Prometheus response rows by label runs
Query output tends to be clustered by series, but a matrix response read
the same label values out of the tag columns once per row, and allocated
a key vector per row to look the series up.
Use `arrow::compute::partition` to find the runs of rows that share their
labels and build the series key once per run. The key buffer is hoisted
out of the row loop and handed to the map only when the series is new,
through the raw entry API so the key is hashed once either way.
Partitioning does not pay off when rows are not clustered, so a few
adjacent row pairs are probed first to pick between the run path and the
row-by-row path. Both paths produce the same series.
Drop the per-row "same labels as the previous row" check from #8815. Runs
cover the clustered case it was written for, and it now costs more than
it saves: 10% on a result with one row per series, 1-3% on clustered ones.
Signed-off-by: Dennis Zhuang <xzhuang@greptime.com>
* refactor(servers): find label runs with cmp::distinct
`arrow::compute::partition` computes the same ranges on the same kernel,
but its contract takes lexicographically sorted columns, and query output
is not sorted: range queries run without the plan's output sort since
#9090, `sort`/`topk` order by value, and the tag column order in the
schema does not have to match any sort key. An implementation that
exploited the precondition would merge `a, b, a` into one run and
attribute one series' samples to another, without failing.
`cmp::distinct` is element-wise, so it holds for any row order, and its
null handling is the one a series key needs: a null label and an empty
one are distinct, two nulls are not. Building the ranges from the
boundary bitmask also folds away the `tag_columns.is_empty()` case, since
no columns means no boundaries means a single run.
Same kernel, so the benchmark does not move: -1.4% to +1.4% across shapes
with no consistent sign, against +-3% run-to-run drift.

`PlanRewriter::should_expand` encoded every node it ascended past to
Substrait. Each call clones the plan, runs an analyzer over it and builds
a fresh `SessionState` with all default features, so a deep PromQL plan
pays that cost once per level.
Encode the root once in `PlanRewriter::new` and skip the per-node call
when it succeeds. `to_substrait_plan` recurses from the root to the
leaves, and `should_expand` only receives sub-trees that `f_down` pushed
on the stack untouched, so a root that encodes proves the whole descent
encodes. A root that does not encode falls back to the per-node check,
which is what locates the node that has to stay on the frontend.

* fix(promql): treat NULL field values as absent samples in range functions
Range functions read the value column through `Float64Array::values()`,
which returns the raw buffer and ignores the null bitmap. A NULL field
value means the series has no sample at that timestamp, so the padding
under a null slot (0.0 in practice) was counted as a real sample.
`rate`, `increase`, `delta`, `changes`, `resets`, `idelta`, `irate`,
`quantile_over_time` and `avg_over_time` now work on samples instead of
slots. `stddev_over_time` and `stdvar_over_time` used to panic on a NULL
slot, and tokio swallowed the panic so the query returned success with
that series missing.
Null handling is gated on `null_count() == 0` over the whole backing
array, checked once per batch, so tables without NULLs keep the existing
code path. `deriv` and `predict_linear` already had this guard through
`linear_regression_slices` and are untouched.

* fix(promql): keep other fields when one has no sample in the window
Review follow-up. Two things surfaced once range functions started
returning NULL for a window without samples.
The filter after a function call required every field column to be
non-NULL, so on a multi-field table one field with no samples in a
window would drop the other fields' results with it. It now keeps a row
when any field has a sample, which is the shape a selector already
emits. On a single field column the two predicates are identical.
`quantile_over_time` returned NaN rather than NULL for a window without
samples, so the row survived that filter. Prometheus returns an empty
vector there, so the emptiness check now sits in the range UDF; the
shared quantile kernel still yields NaN for an empty slice, matching
upstream's `quantile()` helper that `quantile_aggr` depends on.

* docs(promql): correct two comments on the null handling
The planner one did not say why `preserve_any_value` is hardcoded at
that call site, which is the question a reader arrives with. The
`quantile_over_time` one described the empty-window behaviour while
sitting on the `has_nulls` line, and that behaviour had moved into
`window_quantile`.

* fix(promql): clamp extrapolation before snapping a counter to zero
Prometheus clamps `durationToStart` to half an average interval once the
first sample is past the extrapolation threshold, and only then lets the
counter zero-snap shorten it further, so the snap can never lengthen the
leading extrapolation. Running the snap first let it rescue a duration
the clamp should have cut, and `rate` and `increase` over-extrapolated
to the left. For samples 1@0s and 2@1s in a 4s window at 1s, upstream
gives 0.375 and this returned 0.5.
`extrapolation_matches_prometheus_on_seeded_windows` carries a
line-by-line port of upstream `extrapolatedRate` as an oracle and diffs
it against the UDF over seeded windows, so the order stays pinned.
`factor` also picked up upstream's guard against a zero sampled
interval, which previously divided by zero.
Two sqlness results move, both verified against the upstream algorithm.

the same rows.
The merged case keeps every query from both, so the presence functions
still cover the trailing-NULL window, the count of two, the empty
left-open window at t=7, and the all-NULL windows.

* fix(mito2): look up row group stats by parquet leaf index for nested columns
On flat-format tables a logical column can expand to multiple parquet
leaf columns (e.g. a JSON2 struct stores the remainder and one leaf per
promoted path). ParquetFlat used the logical column index in the SST
schema directly as the leaf index when reading row group statistics, so
min/max/null stats of every column after a nested column were read from
wrong leaves.
When the misplaced leaf held order-compatible statistics (e.g. a small
Int64 JSON path vs. the timestamp window predicate), min-max pruning
dropped whole row groups by mistake. SWCS compaction reads inputs with a
time window predicate, so it silently lost all rows of such files; plain
queries with time-range predicates were affected as well.
Map each column to its first parquet leaf column and report NoStats for
columns with multiple leaves, which makes pruning conservative for them.
Add a unit test and a sqlness regression case that reproduces the data
loss on the unfixed binary.

* feat(pprof): switch CPU profiler to framehop unwinder
Replace the default libgcc-based unwinder in pprof-rs with the
framehop unwinder, which is designed to be async-signal-safe:
- framehop performs no heap allocation during unwinding
(MustNotAllocateDuringUnwind)
- It handles prologue/epilogue interruption correctly
- It falls back to frame-pointer unwinding when CFI is unavailable
- It does not depend on libgcc's unwind implementation, which is
documented as not signal-safe (see tikv/pprof-rs#36)
Bump pprof from 0.14 to 0.15 in all three consumers (common-pprof,
cmd, servers) to unify on a single version. pprof 0.15 also replaces
parking_lot with spin-rs to avoid a potential profiler deadlock (#268).
This addresses the libgcc_s.so.1 #GP crash observed in production
when CPU profiling is active, by eliminating the libgcc unwinder
from the signal handler path entirely.

* fix(pprof): gate framehop-unwinder to supported targets
framehop-unwinder is only available on x86_64/aarch64 Linux/macOS.

when framehop-unwinder is set, but the framehop module is not compiled
on unsupported targets, leaving no TraceImpl implementation.
Split the pprof dependency: the base target.'cfg(unix)' block carries
the common features (flamegraph, prost-codec, protobuf), and a separate
target block adds framehop-unwinder only on supported targets.
Cargo unions features from both blocks on matching targets, so x86_64
and aarch64 Linux/macOS get the full feature set while other Unix
targets fall back to the default backtrace-rs implementation.
