Change the REAL-to-INTEGER casting behavior so that if the REAL value is greater than 9223372036854775807.0 then it is cast to the latest possible integer, 9223372036854775807. This is sensible and the way most platforms work in hardware. The former behavior was that oversize REALs would be cast to the smallest possible integer, -9223372036854775808, which is the way Intel hardware works. check-in: 6f53fc71 user: drh tags: trunk

22:24
Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add an assert() to verify that the do-loop really is appropriate. This gives about a 10% performance boost in that routine, or a 0.9% boost overall. check-in: 011a6be4 user: drh tags: trunk

Add the --scratch parameter to speedtest1. Improved error messages when misconfiguring memory parameters in speedtest1. check-in: 8f3c767a user: drh tags: trunk
00:46
The MEMSYS5 algorithm does not have to return the block with the lowest address. Any block of the appropriate size will do. Use the first block found on the freelist for the appropriate size for a performance improvement. check-in: 12e612e8 user: drh tags: trunk
2013-11-23
22:45
A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however.
