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
Other : make table scan skip secondary data pages, propagate record type to the store_big_record to allow record head be stored at the primary record page.
- abandon page checksums and use page number for validation
- PIP have now pip_used field to track number of allocated pages
- two more flag bits per data page is now reserved on pointer page. One is for the swept flag and second is still not used but makes calculations easy
- misc changes
Don't forget to rebuild your DBs !
- Eliminate the useless bumped transaction
- Close the gaps in flags related to indices (btr_* in ods.h)
- Close the gaps in header page clumplets types (HDR_* in ods.h)
- Close the gaps in header page flags (hdr_* in ods.h)
Please do a full rebuild.
- 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.
