v0.2.17

Added

• Added the MySQL 8.4 columns to the constraint and STATISTICS views in information_schema.

Changed

• Routed --format and --result operator output through one result builder, so JSON results from init, config, and serve are complete database.operator.result/v1 objects.

Fixed

• Enforced --idle-session-timeout-ms and --idle-in-transaction-timeout-ms, and reported their values in the matching session variables.
• Reported a missing or uninitialized data directory for database serve as a precondition failure with the same exit code in each output mode.
• Printed a database.operator.result/v1 failure result for an invalid database init with --result=json, and a human result without it.
• Reported "state": "stopped" and the preflight, initializing, and validating phases for database init.
• Emitted the preflight and validating phases for database data validate instead of reading.
• Rejected SET time_zone='-14:00' with MySQL error 1298.
• Returned SQLSTATE 42000 with error 1461 when the prepared statement limit is reached.
• Rejected a column-level CHECK that references another column with MySQL error 3813.
• Rejected foreign keys with incompatible child and parent column types with MySQL error 3780.
• Let DROP INDEX remove a UNIQUE key defined in CREATE TABLE.
• Listed PRIMARY first, then unique keys, then other keys in SHOW INDEX and information_schema.STATISTICS.
• Reported the Null column of SHOW INDEX correctly and filtered SHOW INDEX ... WHERE on displayed values.
• Merged IF result argument types so all rows share one type.
• Kept temporal kind and collation across subquery boundaries in comparisons.
• Keyed row locks and point lookups by the canonical table identity instead of the statement spelling.
