Enhance a debugging log message to better identify a mutex. check-in: e60cb6d8 user: dan tags: debug
14:23

Experimental patch restore the slight bias in btree-balancing immediately after the change to reduces the amount of memcpy() work done by balancing. Leaf check-in: 46bd9533 user: drh tags: btree-balance-bias

In the OP_Column opcode, when extracting a field that is past the end of a short record (because the row was originally inserted prior to ALTER TABLE ADD COLUMN) then make sure the output register is fully NULL and does not contain leftover flags (such as MEM_Ephem) from its previous use. Fix for ticket [43107840f1c02]. check-in: 24780f8d user: drh tags: trunk

08:02
If a free-slot is found within a page, but using that free-slot would fragment the page further and there are already at least 60 fragmented bytes, degragment the page. This matches the behaviour of the trunk. Closed-Leaf check-in: 1f80f8c1 user: dan tags: defrag-opt
07:01
