| 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. check-in: b816023c user: drh tags: trunk | |
| 22:42 | New test case for reading and writing the same rtree concurrently. check-in: 3ba08e53 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: d4ce6661 user: drh tags: trunk | |
