| 16:00 | Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. (check-in: 777189ce88 user: drh tags: trunk) | |
| 13:55 | Add a single sentence of documentation about the virtual table scan flags. No changes to code. (check-in: 27b4fa5dd0 user: drh tags: trunk) | |

| 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: 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) | |
| 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) | |
| 17:25 | Fix a typo in a comment used to generate VDBE opcode documentation. No code changes. (check-in: 36cdfbf2ce user: drh tags: trunk) | |
