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.
Fixed assertion in CCH_exclusive_attachment
Rolled back my changes required to let cancelOperation() enter engine after shutdown
Better locks' history in SyncObject
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.
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
CORE-3502 : DROP VIEW ignores the existing non-column dependencies, and
CORE-3503 : ALTER VIEW crashes the server if the new version has an artificial (aggregate or union) stream at the position of a regular context in the older version.
// Name REL_view is already used in DSQL so i introduced ugly REL_jrd_view flag
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).
