| 23:05 | Fix the built-in edit() SQL function in the CLI so that it works with zero-length blobs. (check-in: e324901286 user: drh tags: trunk) | |
| 21:11 | • Edit [bad4d7a0d93f4d8f|bad4d7a0d9]: Mark "Closed". (artifact: ca328fec1f user: drh) | |
| 21:11 | Attempt to parse the NULLS LAST clause more efficiently. A few cycles were saved, but at the expense of more code. And there is a bug was introduced somewhere. Not worth continuing down this line. (Closed-Leaf check-in: 12d2cf8871 user: drh tags: dead-end) | |
| 20:33 | Move some things in parse.y so that TK_COLUMN and TK_AGG_COLUMN are assigned the same values as they are on trunk for a very small speedup. (check-in: d26fdfa3bc user: dan tags: nulls-last) | |
| 17:09 | Revise the VDBE comments for NULL-scan so that they also work make sense when reading a NULLS FIRST plan. (check-in: bfe793780f user: drh tags: nulls-last) | |
| 17:00 | Additional simplifications of the WHERE loop code generator logic for NULLS LAST. (check-in: 1383680d92 user: drh tags: nulls-last) | |
| 16:12 | Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. (check-in: e3ed2f496f user: drh tags: nulls-last) | |
| 13:32 | Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. (check-in: bf875e1a25 user: drh tags: nulls-last) | |
| 13:08 | Extra VDBE comments in the NULLS LAST logic provide landmarks to help understand the EXPLAIN output. (check-in: 649b08ead5 user: drh tags: nulls-last) | |

| 20:09 | Add the "atrc" test program to the Makefiles. Fix a typo in the instructions in the header comment of the atrc program. (check-in: 2130a407dd user: drh tags: alter-table-rename-column) | |
| 19:32 | Fix harmless compiler warnings in the ALTER TABLE logic. Rephrase an error message to use active voice. (check-in: a7dae59a7e user: drh tags: alter-table-rename-column) | |
| 18:56 | Automatically detect when compiling for AArch64 on windows and set SQLITE_BYTEORDER to little-endian to avoid compile-time testing. (check-in: ef6729be85 user: drh tags: trunk) | |
| 18:50 | The Expr.iColumn field must also be initialized in tokenExpr(). (check-in: 772985f18b user: drh tags: alter-table-rename-column) | |
| 18:22 | Make sure the Expr.iTable field is initialized by tokenExpr(). (check-in: 02a05a3b3c user: drh tags: alter-table-rename-column) | |
| 14:54 | Merge enhancements from trunk. (check-in: c446c88411 user: drh tags: rtree-geopoly) | |

| 23:09 | Performance optimization to pageFindSlot() in the b-tree layer. (check-in: 59560d079f user: drh tags: trunk) | |
| 20:36 | Size and performance optimization to dropCell() and freeSpace(). (check-in: bc1ec123ce user: drh tags: trunk) | |
| 14:45 | Smaller and faster implementation of the fillInCell() routine. (check-in: 77074990ed user: drh tags: trunk) | |

| 19:02 | Simplify the row value misuse error message. (check-in: 838c50a5bf user: drh tags: rowvalue) | |
| 19:02 | Add further tests for changebatch. And a fix to prevent a changeset from conflicting with itself. (check-in: 506d6ff4b6 user: dan tags: changebatch) | |
| 18:30 | Fix a problem with rowvalue UPDATE when the rowvalue is not the left-most and the RHS is a multi-column subquery. (check-in: e149e6b93a user: drh tags: rowvalue) | |
| 18:09 | Fix harmless compiler warnings in changebatch. (check-in: a721a73818 user: drh tags: changebatch) | |
| 17:30 | Fix an uninitialized variable in CASE expression code generation. (check-in: c8ffae05e1 user: drh tags: rowvalue) | |
| 17:02 | Add a new method to sessions - sqlite3sessions_fullchangeset() - to return a changeset that always contains values for all old.* fields. Update changebatch to use these values to more reliably detect multi-column UNIQUE constraint violations. (check-in: efa761b2f5 user: dan tags: changebatch) | |
| 14:42 | Fix the SQLITE_USER_AUTHENTICATION login check so that the SQLITE_AUTH_USER error code correctly propagates and is not overwritten by SQLITE_ERROR. (check-in: c640489db2 user: drh tags: trunk) | |
