20:53
Incremental check-in: Progress toward implementing the geopoly vtab. check-in: 9b7d6f986a user: drh tags: rtree-geopoly

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: 0593aac88a 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. Leaf check-in: 6f7cfeff70 user: drh tags: rtree-update-optimization
09:36
Merge latest trunk changes into this branch. check-in: 6232519899 user: dan tags: exp-window-functions

2018-05-24
23:51
When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate. This allows one-pass to work on virtual tables that do not allow concurrent reads and writes. Enhance rtree to take advantage of this new capability. Leaf check-in: b816023ce0 user: drh tags: trunk
22:42
New test case for reading and writing the same rtree concurrently. check-in: 3ba08e53d5 user: drh tags: trunk
22:31
Do not allow RTree writes when a read cursor is active on the same virtual table, as the writes might rebalance and disrupt the read cursors. Return the new SQLITE_LOCKED_VTAB error code if this happens. check-in: d4ce666108 user: drh tags: trunk
21:10
Allow "<expr> PRECEDING" to be used to specify the end of a window frame. check-in: 7b709a989c user: dan tags: exp-window-functions

17:38
In the OOM testing logic, add the sqlite3FirstFault() routine as a place to set a breakpoint the first time any simulated OOM fault occurs for a single test case. check-in: b4d80bd287 user: drh tags: trunk

16:50
Verify that the sqlite_sequence table exists and is in approximately the correct format prior to using it to process an autoincrement table. Fix for ticket [d8dc2b3a58cd5dc2918a1d4a]. check-in: e199e859ac user: drh tags: trunk
