19:38 | Add the PRAGMA table_vinfo command (with an extra "v" before "info") that works like PRAGMA table_info (without the "v") except that it also shows hidden columns on virtual tables. (check-in: 8bcd1a59 user: drh tags: pragma-table-vinfo) | |

20:19 | Fix the handling of sub-queries with LIMIT clauses by the optimization activated by compile-time symbol SQLITE_COUNTOFVIEW_OPTIMIZATION. (check-in: 21235d9a user: dan tags: trunk) | |
15:58 | Fix the OP_SeekRowid opcode so that it has no type-change side-effects on the key register in P3. This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time. Test cases for this fix are in TH3. (check-in: fa94b49e user: drh tags: trunk) | |
13:56 | Improve "PRAGMA vdbe_trace=ON" to always show the key values for the OP_IdxGT and related opcodes. (check-in: 0f881955 user: drh tags: trunk) | |

18:56 | In the command-line shell, always exit if realloc() fails. (check-in: e390023c user: drh tags: trunk) | |

21:01 | Add a small cost penalty to sorting to bias the query planner in favor of plans that do not require a final sorting pass. (check-in: 85b9beb4 user: drh tags: trunk) | |
16:24 | Do not allow a column reference that is converted into a constant by the WHERE-clause constant propagation optimization to be moved to the init-time constant expression list, as the table reference will not work there. This fixes a problem found by OSSFuzz. (check-in: d30b2a94 user: drh tags: trunk) | |
