88b8a40a04 1. Cleaned up most of SUPERSERVER usage. 
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.

3b5a0fdae5 The way AccessItem instances were ordered was a hack that sooner or later would fail when adding more object types (that now have ACLs but we still don't enfornce them). Further, comparing numbers is faster than comparing strings. 2010-02-13 08:31:16 +00:00

dimitr
d35f6e316b 1) Simplify the explicit plan handling between the parser and the engine. It makes no sense to pass the join type as it's ignored internally. 
2) Support hash joins in the plan output and in the parser. For the latter, it's just the syntax sugar, same as loop vs merge join (see above).

11495a55fb Refactored the whole RSB stuff into classes. They're inside the /recsrc sub-directory now. 
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Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).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.

ed0e0daeb3 - External Engines implementation. 
- 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.

2b87e94242 Use explicit iterators instead of the implicit (built-in) ones due to the thread-safety requirements. 
This change affects GenericMap only, as it's used globally in a few places and we have a proven crash there.
I have a more complete solution (total cleanup of default accessors from BePlusTree and SparseBitmap) in my local tree (thanks to Dmitry Kovalenko), but it's incomplete (requires more changes inside the engine) and IMHO risky (~20 core modules are affected), so I'd like to defer finalization of this cleanup till v3.0.
All objects of these types seem being protected by dbb_sync, so they shouldn't cause us any problems currently.
