d9c0e9548c Fixed three issues together represented in CORE-4261: 
- non-existent result of the window function (in outer joins) is reported as 0 instead of NULL
- derived constant is processed wrongly in windowed streams
- deeper-than-root partitions are not "nullified" in outer joins
Adriano, please review.

c1cbd97163 Increased the sort record size limit to 1MB. I've kept this limit due to the possible performance implications, but it can be extended/removed any time. 2013-08-21 09:11:57 +00:00

e0567463bf Revert external routines to request-based (*) code, but now using a totally different internal approach. 
* This is not ideal IMO, but much more easier to currently support stack traces, and domain's defaults and validations.

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.

f30f9e58e8 Reworked the fix for CORE-3683: Recursive query with GROUP BY in root part: wrong results if no index exists for fields that are grouped. It resolves some optimization regressions appeared after the original fix. 2011-12-14 06:45:24 +00:00

965bf3f159 Fixed the problem with windowed functions in recursive CTEs, reported by Frank Ingermann in fb-devel. 
This fix is complementary to the one done in CORE-3683.

9b8171d5c1 1) Refactor nod_value_if. 
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).
