Forward port the geopoly extension functions into the r-tree extension, with the idea of creating a new spatial index based on simply polygons. (check-in: 0593aac8 user: drh tags: rtree-geopoly)
14:39
This is an untested proof-of-concept for enhancements to RTree that attempt to use sqlite3_value_nochange() to reduce the amount of work associated with UPDATE operations in cases where either the coordinates or the auxiliary data is unchanged.

11:39
The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes to be issued for references to the right-hand side table of *any* flattened join, not just LEFT JOINs. This puts extra stress on the OP_IfNUllRow opcodes for testing purposes. (check-in: 1a074c8a user: drh tags: branch-3.19)
00:28

00:08
The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. (check-in: 77fc2301 user: drh tags: trunk)

First code for a new utility program to rerun checks on a large number of fuzzer-generated test cases. (check-in: c5b4e363 user: drh tags: fuzzcheck)
18:47
Fix a couple of btree asserts that would fail when encountering 32-bit rollover in cell payload size fields (cell payloads this large always indicate corruption). (check-in: 8fa0937a user: dan tags: trunk)
