bf82df1ebb Postfix for CORE-3242: somewhy when checking metadata access (like MODIFY or DROP) always checked that access from object itself. Strange at the first glance behavior, but let us do not change legacy (at least since FB1.0) when possible. 2014-05-07 11:21:31 +00:00

6fcd20e73f Experimental way of stopping gbak impersonation in sys tables. Gbak only needs to write to sys tables when it's restoring and only in the first attachment. Second and third attachment are for bringing the DB online and setting the R/O flag. Please test. 2014-04-10 01:39:32 +00:00

de7ed79414 Fixing several issues with my previous commit: 
Use increment [by], no step.
Enable again code in ini.epp because it's needed when restoring (but not when creating gens directly in a new db).
Gbak has code to fix system generators and we should allow it.
Nbackup cannot update the history generator when doing a backup.
Field name renamed to rdb$generator_increment.

29e36dc4f3 The 0th generator becomes unnamed. Only internal requests can access it (zero length names are not allowed from outside). RDB$GENERATORS is no longer a reserved name.System generators cannot be changed by user requests, but can be queried with gen_id(g, 0) if the permissions (ACL) allow that. We don't track dependencies on sys generators, it's not necessary. 2014-04-04 06:39:09 +00:00

5) Refactored SET GENERATOR and ALTER SEQUENCE as true DDL. blr_set_generator is supported only for backward compatibility, it's not generated by DSQL anymore.
6) Added START WITH clause for [RE]CREATE SEQUENCE and CREATE OR ALTER SEQUENCE.
7) Fixed a number of related errors.

70d5ebdfdf - Got rid of the fixed array that kept the stream count in the first element and 255 streams after it. 
- Changed streams from UCHAR to ULONG as Dmitry wanted
- Got rid of some redundant flags to indicate BLR level
- Misc changes (for example, converted to test for DBB_read_only in Database to a function)
- BLR v6 is left commented (waiting for a better solution to appear, if any exists)
- This change is not going to raise the engine limits until a solution is found to express more than 255 streams in BLR.

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).

33155c65b7 An alternative way to assign auto-generated metadata IDs while restoring a database. It doesn't require system triggers. 
If nobody objects, I will migrate procedure/exception/generator IDs to this approach and then redo my system triggers cleanup.

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.

3c65def766 - Better input type for SQZ_decompress plus a bit of style.
