Store ValueExprNodes instead of jrd_nod in the metadata cache.
Make RecordSourceNode child of ExprNode as they share most operations.
Get rid of the JRD visitors in favor of direct calls.
Convert assignments statement lists created inside expressions to separate source and targets ValuesExprNodes.
2) Created ExprNode::expressionEqual method to replace a new big and ugly switch.
3) Make boolean referencers use BoolExprNode instead of jrd_nod, except nod_validate for now. This includes BinaryBoolNode and NotBoolNode working without jrd_nod references.
4) Rework in the impure allocation code (replace "csb_impure += ..." by CMP_impure calls).
SUPERSERVER has 4 different meanings in our code:
- this is milticlient server (replaced with Config::getMultiClientServer())
- use shared data cache (replaced with Config::getSharedCache())
- use shared metadata cache (replaced with macro SHARED_METADATA_CACHE)
- database are NOT shared between processes (replaced with getSharedDatabase())
2. Use fb_smp_server as both superclassic and classic binary on posix
(xinetd autodecection is done).
3. Small posix build cleanup.
Convert CONCATENATE and aggregate functions to it.
Fix some bugs:
- select sum(n) over (order by n2), sum(n) over (), n, n2 from x1;
- select (select 1 from x1 b where list(1, a.n) = 1) from x1 a;
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Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).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.
2) Make exceptions in metadata charset and convert them to the client charset - this should fix CORE-2431
3) Support for "internal" (engine) DSQL statements and use in COMMENT ON
