Avoid use of circullar allocation for strings in status vector (except when unavoidable for ISC API backward compatibility).
Use TLS for circullar allocation buffer instead manually working with threads' list.
2. Implemented prototype of TLS-based debugging helper holding information about 'What does firebird do now?"
Currently it's more or less ready for use with JAttachment::release().
Fixed assertion in CCH_exclusive_attachment
Rolled back my changes required to let cancelOperation() enter engine after shutdown
Better locks' history in SyncObject
2) Reworked the lock manager synchronization: added the RAII mutex holders and avoided dirty reads for the shared memory.
3) Encapsulated lck_length into the Lock class + small related refactoring.
4) Front ported recent fixes from the v2.x branches.
5) Misc cleanup.
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
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.
- 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.
