| 23:52 | Minor simplifications to the "zeroPage()" routine in btree.c. check-in: cc8f10bc user: drh tags: trunk | |
| 21:31 | Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. check-in: 56bc5ce8 user: drh tags: trunk | |
| 14:43 | Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Fix for ticket [c34d0557f740c45070]. check-in: 5d01426d user: drh tags: trunk | |

| 16:22 | Updates to the command-line shell. Simplify the banner message. Add the ".save" command as an alias for ".backup". When starting with no arguments, include a banner message warning that the database is transient and in-memory and mention the ".open" command. check-in: f5ad1e1b user: drh tags: trunk | |
| 14:37 | Fixes to the "editline" support in the command-line shell. check-in: 7989ce5f user: drh tags: trunk | |

| 23:20 | Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. check-in: 1e64dd78 user: drh tags: trunk | |
| 19:12 | Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] check-in: e2303d1b user: drh tags: trunk | |

| 01:40 | Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. check-in: 192dea97 user: drh tags: trunk | |
|
2014-02-07

| 18:27 | Get rid of the OP_Undef and OP_IsUndef opcodes in favor of higher-level OP_InitCoroutine and OP_EndCoroutine. check-in: 1ec0e9dd user: drh tags: coroutine-refactor | |
| 13:20 | Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. check-in: 6fb74485 user: drh tags: coroutine-refactor | |

| 23:45 | Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. check-in: f2504089 user: drh tags: trunk | |
| 20:46 | Remove the SF_Materialize flag from the SELECT object as it does not accomplish anything useful. check-in: 65d5dcdd user: drh tags: trunk | |
| 15:55 | Rearrange fields in the Parse object for a tighter packing, resulting in an 8% size reduction on x64. check-in: 3e1a3f68 user: drh tags: trunk | |

The OP_SwapCursors opcode is no longer required.
