Developer's Report: Firebird INTL/DSQL Development
December 2010 to February 2011

February 2011

HEAD
  • Fixed CORE-3330 - Server crashes while recreating the table with a NULL -> NOT NULL change.
  • Fixed CORE-3201 - ATAN2 returns incorrect value for (0, 0).
  • Fixed a problem with COUNT in dialect 1.
  • Fixed CORE-3310 - RDB$GET_CONTEXT and between in view.
  • Fixed CORE-3338 - Some expression indexes with COALESCE, CASE and DECODE became inoperant.
  • Removed DSQL hidden variables expressions.
  • Refactored COALESCE, DECODE and (simple) CASE, using new BLR verbs.
  • Fixed v3 regression with UPDATE OR INSERT inside PROCEDURE/FUNCTION.
  • Fixed assert with DECODE/CASE with only test parameters and no values.
  • Fixed CORE-3255 - The server could crash using views with GROUP BY.
  • Do not reuse arbitrary nodes' impure space in aggregate. Relates to CORE-3255.
  • Fixed hang found with CORE-3340 test-case.
  • Simplified fix for problem with default values in formats.
  • Fixed DDL trigger crash reported in fb-devel.
  • Fixed problem with packages reported privately by Vlad.
  • Refactored out OPT_expression_equal while fixing checking of sameAs involving CASTs. Problem saw by Dmitry.
  • Added EVENT_TYPE and OBJECT_TYPE to DDL_TRIGGER context. Improvement suggested by Thomas Steinmaurer.
  • Updated TCS tests for FB 3.
  • Removed the legacy DSQL hash table module (HSHD).
  • Various DSQL refactorings.
2.5 Branch
  • Backport simplified fix for CORE-3255 - The server could crash using views with GROUP BY.
January 2011

HEAD
  • Fixed CORE-3306 - Invariant sub-query is treated as variant thus causing multiple invokations of a nested stored procedure.
  • Fixed CORE-3320 - Some MERGE syntax can crash the server.
  • Made the UDR engine work correctly with the new plugins code.
  • Fixed recursive query with ORDER BY.
  • Various DSQL refactorings
V2.5 branch
  • Backported fix for CORE-3306 - Invariant sub-query is treated as variant thus causing multiple invokations of a nested stored procedure.
  • Backported fix for CORE-3320 - Some MERGE syntax can crash the server.
V2.1 branch
  • Backported fix for CORE-3320 - Some MERGE syntax can crash the server
December 2010

HEAD
  •  
  • Make statement evaluation faster, reworking line/column handling.
  • Make expression evaluation faster, using more inlining.
  • Use the impure space of string variable in a consistently (first or subsequent request execution) and optimized (no double allocation) way.
  • Fixed CORE-2204 - Constraints on SP output parameters are checked even when the SP returns zero rows.
  • Feature CORE-726 - Boolean data type.
  • Fixed the crash about NEXT VALUE FOR reported in fb-devel.
  • Various DSQL refactorings.
