or as dynamic library, depending upon platform requirements). Self-registering plugins
need not export any functions, instead they call fb_register_plugin() on startup.
Reworked all user management to use self-registering plugins.
Removed system table RDB$USERS. PLG$USERS is not created automatically by plugin, but
will be later (work in progress).
Fixed the layering for WITH LOCK and (partially) ANY/ALL predicates.
Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).
Wiped out a lot of the pre-ODS11 optimizer logic. Some minor adjustments there.
Re-implemented the full outer join from scratch. This resolves CORE-2678 (full outer join cannot use available indices).
Resolved CORE-2796: DB_KEY is always zero for external tables.
Implemented the core part of the scrollable PSQL cursors. Implementation is still incomplete, but ready for testing.
Some other changes I don't recall at the moment ;-)
WARNING! The engine may be unstable. Please email me about any issues found.
CORE-462 New option in addition to -V switch to specify a custom verbose interval
CORE-2540 Utilities need a more coherent way to show help and version
CORE-2541 Too many hardcoded messages in nbackup
CORE-2542 qli and nbackup accept arbitrary input after the first letter of an option
CORE-2543 nbackup may hide the real cause of failure
CORE-2545 Lack of several validations in gbak
CORE-2547 Utilities need to honor their minimum number of characters to recognize an option
CORE-2565 Many hardcoded messages in Trace Manager
Moving functions that don't depend on preprocessing to iutils.cpp in isql is the only alien change here.
- 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.
