* test: cover windowed sort cast unit mismatch Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * fix(query): stop windowed sort on unit- or timezone-changing time casts A cast on the time index column keeps the windowed-sort optimization eligible only when it preserves the underlying timestamp values. Casts that change the time unit (e.g. ms -> s) or that add a timezone to a naive timestamp re-interpret the values, so the working ranges derived from the time index no longer describe the sort column and the scan fails with a working-range error or silently wrong order. Reject both cast shapes so such queries fall back to the normal SortExec path. The integration fixture uses two rows 1000 seconds apart so the cast output stays distinct and the ordering assertions are not vacuous; the descending arm gets its own expectation. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * fix(query): stop windowed sort on unit-changing timestamp wrappers to_timestamp_seconds/millis/... cast their argument to their own unit inside the function, so the hidden cast bypassed the explicit-cast guard and kept the windowed-sort optimization eligible on a sort column whose values no longer match the working ranges. The wrapper branch now applies the same unit- and value-preserving predicate as the cast branch, with the predicate extracted into preserves_timestamp_values and shared by both. The integration regression gains to_timestamp_seconds ASC/DESC arms and a to_timestamp_millis value-preserving control; unit tests cover unit-changing, tz-adding, and non-timestamp wrapper inputs. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * test: regen windowed sort sqlness after wrapper guard The windowed_sort_nanos and windowed_sort_advance cases sort by to_timestamp_nanos over a millisecond index and to_timestamp_millis over a nanosecond index. Both wrappers change the time unit inside the function, so the windowed-sort rule no longer applies and the plans render a plain SortExec. Query results are unchanged; only the EXPLAIN plan line differs. Regenerated by the sqlness runner.

Sqlness Test
Sqlness manual
Case file
Sqlness has two types of file:
.sql: test input, SQL only.result: expected test output, SQL and its results
.result is the output (execution result) file. If you see .result files is changed,
it means this test gets a different result and indicates it fails. You should
check change logs to solve the problem.
You only need to write test SQL in .sql file, and run the test.
Case organization
The root dir of input cases is tests/cases. It contains several subdirectories stand for different test
modes. E.g., standalone/ contains all the tests to run under greptimedb standalone start mode.
Under the first level of subdirectory (e.g. the cases/standalone), you can organize your cases as you like.
Sqlness walks through every file recursively and runs them.
Kafka WAL
Sqlness supports Kafka WAL. You can either provide a Kafka cluster or let sqlness to start one for you.
To run test with kafka, you need to pass the option -w kafka. If no other options are provided, sqlness will use conf/kafka-cluster.yml to start a Kafka cluster. This requires docker and docker-compose commands in your environment.
Otherwise, you can additionally pass the your existing kafka environment to sqlness with -k option. E.g.:
cargo sqlness bare -w kafka -k localhost:9092
In this case, sqlness will not start its own kafka cluster and the one you provided instead.
Run the test
Unlike other tests, this harness is in a binary target form. You can run it with:
cargo sqlness bare
It automatically finishes the following procedures: compile GreptimeDB, start it, grab tests and feed it to
the server, then collect and compare the results. You only need to check if the .result files are changed.
If not, congratulations, the test is passed 🥳!
