* fix(auth): warn when credential load disables Postgres SCRAM or drops a line (#8652)
* fix(auth): warn when credential load disables Postgres SCRAM or drops a line
Static and watch user providers degraded silently in two ways:
- A single non-SCRAM verifier (mysql_native_password, or a legacy
pbkdf2_sha256 hash that predates SCRAM) disables Postgres SCRAM for
every user and falls back to cleartext, with no signal to the operator.
- A malformed credential line (commonly a plaintext password containing
'=', which splits into more than two parts) was dropped without a trace.
Emit a warning at each credential load for both cases so operators don't
unknowingly serve cleartext passwords over Postgres or lose a user. This
is logging only; authentication behavior is unchanged. The SCRAM check
never logs secrets, and the malformed-line warning logs the line number
and file, never the line content.

* fix(auth): warn on credential file read error before truncating
A read error from lines() (I/O failure or invalid UTF-8) ends the
iterator via map_while, silently dropping every remaining credential.
Warn with the line number and file before truncating, matching the
malformed-line handling, so the drop is observable.

* perf(promql): avoid repeated scans in sliding range evaluation (#8646)
* perf(promql): use two pointers for sliding range boundaries
Replace the stale cursor heuristic in RangeManipulateStream::calculate_range
with monotonic left/right cursors. The old path rescanned each evaluation
window (O(E x samples-per-window)) and could lose valid samples after sparse
gaps or trailing empty windows. The two pointers keep strict monotonic
progress, reducing boundary generation to O(N + E) while preserving
(curr-range, curr] semantics, start/end shortening, and empty-window output.
Controlled release benchmarks (fixed CPU, ABBA):
- Public RangeManipulate wall time: ~28% faster at 1m/15s, ~66% at 5m/15s,
~96% at 1h/15s.
- Warmed distributed TQL ANALYZE 1h queries: ~17-21% faster end to end;
shorter windows stayed within run-order noise.
Signed-off-by: discord9 <discord9@163.com>
* perf(promql): specialize changes/resets with adaptive edge counting
The generic range_fn macro slices, downcasts, and rescans every overlapping
window for changes() and resets(). Replace the macro path for these two
functions with hand-written UDF wrappers backed by a shared private
edge-count kernel: direct raw-offset scans when requested edges are few,
otherwise one global u64 edge prefix so each window is answered by a prefix
difference.
Behavior is preserved bit-for-bit, including raw null-buffer values, NaN
semantics, signed zero, infinities, empty/singleton windows, independent
timestamp/value offsets, arbitrary window layouts, and exact DataFusion
error messages. The shared proc macro, planner, serializer, and other range
functions are untouched.
Controlled release benchmarks (fixed CPU, ABBA):
- Dense sliding windows (k=4/20/240): 91.7-95.6% less public UDF wall time.
- Low-coverage fallback (N=4096, 8 windows): 73.9-74.4% faster.
- Warmed distributed TQL ANALYZE 5m/1h changes/resets: 12.1-19.7% client
and 12.0-20.9% server latency improvement; controls stayed within drift.

* ci(query-regression): include PromQL range boundary case in defaults

promql_range_boundary case (introduced in #8646) into DEFAULT_CASES so
label-triggered runs measure the range path. The case is cheap: a ~0.3s
synthetic fixture and about a minute of query execution per base/candidate
pass.

* docs: show stable, latest and nightly version badges in README
The single release badge rendered whatever GitHub considered newest, so a
pre-release such as v1.2.0-beta.1 looked like the recommended version.
Split it into three self-updating badges using the shields.io `filter`
parameter, keyed off the existing tag naming:
- stable: `!*-*` matches tags without a hyphen (v1.1.4)
- latest: `!*-*-*` excludes nightly and dev builds (v1.2.0-beta.1)
- nightly: `*-nightly-*` matches the weekly build (v1.2.0-nightly-20260706)
No workflow changes are needed; the badges track new releases on their own.
A one-line caption below them says which channel to pick. The release-date
badge is dropped as the three version badges already carry that signal.

* chore: check enterprise-gated files are listed in both license configs
A file reachable only through `#[cfg(feature = "enterprise")] mod ...;` is
governed by the GreptimeDB Enterprise License, so it must appear in the
`includes` of licenserc-enterprise.toml and the `excludes` of licenserc.toml.
hawkeye stays silent when it does not: the file keeps its Apache-2.0 header and
passes the default check precisely because it was never excluded from it.
scripts/check-enterprise-license.py walks enterprise-gated `mod` declarations,
resolves them to files (submodules included) and diffs that set against both
configs, also reporting stale entries. It runs in the license job in CI and as
`make check-enterprise-license`.
Documents the split it cannot decide for you — whole enterprise features get
their own file, a gated match arm stays inline — in

- common-meta procedures, tombstone keys, and DdlTask serde stay
unconditional for persisted-procedure recovery and wire compatibility

The example TOMLs and generated config.md documented the default of
wal.sync_period as "10s", but since #5677 moved the WAL sync task to a
background RepeatedTask, an unset sync_period falls back to 5s in
RaftEngineLogStore. The two paths therefore had different fsync
periods: deployments based on the example configs used 10s while bare
configs used 5s.
Align the documentation with the actual code behavior (5s) instead of
changing the code fallback to 10s, so that no existing deployment
silently gets a larger data-loss window on host power loss.
- config/datanode.example.toml, config/standalone.example.toml: 10s -> 5s

Adds json_fields_compatible(): JSON fields are equal when name and
nullability match, greptime:type matches, and the JSON2 settings
(ARROW:extension:metadata type hints) match, ignoring the physical arrow
type. Only JSON fields may bypass the raw-type comparison; non-JSON
validation stays strict.
Adds 4 regression tests mirroring the CI failure (wire-binary vs
decoded-struct accepted both directions; different JSON2 settings
rejected; JSON vs plain Binary rejected).

* feat: support defer_on_missing_source for pending flow creation
Add `defer_on_missing_source` flow option that allows creating flows
even when source tables do not yet exist. The flow enters a pending
state and is automatically activated when source tables become available.
Key changes:
- New `FlowStatus::PendingSources` and fields in `FlowInfoValue` for
unresolved source table names and last activation error
- `defer_on_missing_source` create-time-only option: stripped from
runtime/flownode `CreateRequest` but preserved in metadata for
SQL round-trip (`SHOW CREATE FLOW`, `information_schema.flows`)
- `CreateFlowProcedure` creates pending metadata when sources are
missing and `defer_on_missing_source=true`; falls back to
`FlowType::Batching` for missing-source flows
- `PendingFlowReconcileManager` in meta-srv periodically checks
pending flows and activates them when source tables resolve
- `ActivatePendingFlowProcedure` handles activation: allocates peers,
creates flows on flownodes, updates metadata, invalidates cache
- `OR REPLACE` properly handles pending<->active transitions,
including peer allocation and flownode flow teardown
- `FlowMetadataAllocator::alloc_peers` for peer allocation at
activation time
- Validated flow options: only `defer_on_missing_source` allowed;
unknown options rejected
- Known issue: standalone mode does not support flownodes, so
pending flow flush/sink behavior covered only in distributed
sqlness; operator and meta unit tests cover activation logic
Tests:
- operator `determine_flow_type_for_source_state` (3 passed)
- common-meta `create_flow` (19 passed) including replacement
- common-meta `activate_flow` (4 passed)
- meta-srv `flow` (11 passed)
- sqlness: `flow_pending` covers create/replace/round-trip
Signed-off-by: discord9 <discord9@163.com>
* chore: simplify pending flow PR scope
Reduce PR #8124 to the metadata-only MVP after complexity review.
Changes:
- Remove automatic activation procedure and meta-srv reconcile wiring
- Remove activation tests and activation-only metadata fields
- Reject cross-state pending<->active `OR REPLACE` transitions for now
- Keep pending metadata creation and SQL round-trip behavior
- Allow `DROP FLOW` for pending flows without routes
- Reduce flow_pending sqlness to metadata/round-trip/drop coverage only
Deferred follow-ups are documented locally in `.tmp/tasks/pending-defer-semantics/deferred-followups.md` and intentionally not committed.
Tests:
- `cargo test -p operator determine_flow_type_for_source_state`
- `cargo test -p common-meta create_flow`
- `cargo test -p common-meta drop_flow`
- `cargo sqlness bare --test-filter flow_pending --bins-dir /mnt/nvme_rust/rust-targets/pending_defer/debug`

* fix unit tests
* fix: sqlness
* fix/default-time-window:
## Add Helper Functions and Enhance Compaction Tests
- **Refactor Compaction Logic**: Introduced helper functions `flush` and `compact` in `compaction_test.rs` to streamline compaction operations.
- **Enhance Compaction Tests**: Added a new test `test_infer_compaction_time_window` in `compaction_test.rs` to verify compaction time window inference.
- **Testing Improvements**: Added `#[cfg(test)]` attribute to `new_multi_partitions` in `time_partition.rs` to ensure it's only included in test builds.
* fix/default-time-window:
- **Refactor `TimePartition` Struct**: Removed unnecessary comments regarding `time_range` in `time_partition.rs`.
- **Enhance `TimePartitions` Functionality**: Added a method `part_duration_or_default` to provide a default partition duration in `time_partition.rs`.
- **Update SQL Test Cases**: Modified SQL operations and expected results in `scan_big_varchar.result` and `scan_big_varchar.sql` to reflect changes in data manipulation logic.
* fix/default-time-window:
### Update Time Partition Default Duration
- **Refactor Default Duration**: Introduced `INITIAL_TIME_WINDOW` constant to define the default time window duration as `Duration::from_days(1)`. This change replaces multiple instances of the hardcoded default duration across the `time_partition.rs` file.
- **Files Affected**: `time_partition.rs`
* fix/default-time-window:
## Update Partition Duration Handling
- **`time_partition.rs`**: Refactored `part_duration` to be non-optional, removing `Option` wrapper. Updated logic to use `unwrap_or` with `INITIAL_TIME_WINDOW` where necessary. Adjusted related methods and tests to accommodate this change.
- **`version.rs` (memtable and region)**: Updated handling of `part_duration` to align with changes in `time_partition.rs`, ensuring consistent use of non-optional `Duration`.
* fix/default-time-window:
### Improve Error Context in `time_partition.rs`
- Enhanced error context message in `time_partition.rs` to provide clearer information on partition time range issues, including bucket size details.
