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.
Also propagated the sysflag/owner/secclass assignment and validation to all object types and wiped out the duplicating system triggers.
Warning: testing is required!
2) Reimplemented the USAGE privilege as a separate one.
3) Added USAGE permission checks for generators/sequences and exceptions.
4) Supported USAGE in GRANT/REVOKE for all object types.
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.
1. Frontported fix for CORE-3935 and CORE-3993.
2. Added debugging support for mutexes and rwlocks in Vulcan style.
Unfortunately after last 'svn up' build asserts in JrdStatement:71.
- SubQueryNode (sub-select's) and RseBoolNode (exists(), in\any\all) now knows if it is a part of some outer select (ForNode) or it is a standalone statement.
- VIO\get_undo_data was reworked to better fit undo-log implementation, corresponding changes in VIO_chase_record_version also done
- AV in VIO\get_undo_data was fixed
CORE-3656 : Support for sweep information in Trace API, and
CORE-2668 : Write note into log when automatic sweep is started
Also per-table stats is enabled at transaction level (see thread_db::bumpRelStats)
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.
- 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.
- moved relation's counters into RuntimeStatistics.h
- renamed RuntimeStatistics::bumpValue to RuntimeStatistics::bumpRelValue and thread_db::bumpStats to thread_db::bumpRelStats to make things more clear
- removed not obvious cast in VIO_bump_count
- removed dependency of RuntimeStatistics.h from ntrace.h
2) Opened the gates to implement the standard USAGE privilege (CORE-2884). SQL support and validation logic are still to be developed.
3) Added the grant option to the owner permissions for packages, procedures and functions.
4) Misc cleanup and refactoring.
