2) Reimplemented the USAGE privilege as a separate one.
3) Added USAGE permission checks for generators/sequences and exceptions.
4) Supported USAGE in GRANT/REVOKE for all object types.
5) Refactored SET GENERATOR and ALTER SEQUENCE as true DDL. blr_set_generator is supported only for backward compatibility, it's not generated by DSQL anymore.
6) Added START WITH clause for [RE]CREATE SEQUENCE and CREATE OR ALTER SEQUENCE.
7) Fixed a number of related errors.
- SubQueryNode (sub-select's) and RseBoolNode (exists(), in\any\all) now knows if it is a part of some outer select (ForNode) or it is a standalone statement.
- VIO\get_undo_data was reworked to better fit undo-log implementation, corresponding changes in VIO_chase_record_version also done
- AV in VIO\get_undo_data was fixed
Also some cleanups, the most important are:
- meaningful ctor on Jrd::Lock, helping to avoid code dup
- avoid unneeded h-file dependencies, making boot build engine dependent
2. Avoid massive segfaults when closing heavily loaded server.
3. Restored logic in YValve required for correct shutdown.
4. Do not change externally visible request body when preparing it.
It's better to have one standard than two, and "ddl" was broken from API POV.
So make the IAttachment always the caller, explicit or implicit (via IStatement or IRequest), and pass the ITransaction as parameter.
Use traditional firebird configuration files format in all places (intl, trace, etc.).
Add per-database configuration facility to aliases.conf (currently 15 parameters from firebird.conf).
- Renamed CompiledStatement to DsqlCompilerScratch and removed inheritance to dsql_req.
- Introduced DsqlCompilerStatement, moving things from dsql_req - not completelly shareable yet.
- Make dsql_req reference a DsqlCompilerStatement. DsqlCompilerScratch may be discarded in the future.
- Replaced AlterCharSetNode usage by PreparedStatement for the default collation in database creation.
- Changed METD API.
- Plugins API.
- Feature CORE-2700 - UDR (User Defined Routines) Engine - C++ API supporting functions, triggers and stored procedures.
- Feature CORE-2470 - Support for alternate format of strings literals.
- Feature CORE-2310 - DDL triggers.
- Feature CORE-2312 - PSQL Packages.
- Feature CORE-1209 - CONTINUE statement.
- Feature CORE-1180 - DDL syntax to change (not) nullable state of columns.
- Feature CORE-2090 - Support OVER () clause with current aggregate functions.
- Fixed CORE-2699 - Common table expression context could be used with parameters.
- Introduce ODS 12.0.
- Work in progress in type-safe parser.
- Refactor some DDL commands (procedures and triggers) from DYN to DdlNodes.
- Refactor virtual tables to use a class hierarchy instead of namespaces. This is basic thing, not based on the changes done in Vulcan. Window functions is based on this work.
- Refactor COMMENT ON and DROP FUNCTION from DYN to DdlNodes. COMMENT ON do not use GDML anymore, it uses DSQL with PreparedStatement class.
- Refactor EXECUTE BLOCK to StmtNodes.
- Refactor the IUDF to SysFunctions. That eliminates RDB$GET_CONTEXT and RDB$SET_CONTEXT from RDB$FUNCTIONS.
