| ||
| 19:48 | Fix harmless compiler warnings in the command-line shell and in Lemon. check-in: afcdc4a6 user: drh tags: trunk | |
| 17:25 | In kvtest.c, use stat() instead of fseek()/ftell() to determine the size of a BLOB to be read directly from disk. This makes the pile-of-files database more competative against SQLite. check-in: a7dca29f user: drh tags: trunk | |

| 01:41 | Remove an incorrect ALWAYS() macro from balance_nonroot(), which could result in corrupt databases if it were optimized out. This ALWAYS was added only two weeks ago (check-in [f9f2e23bbd68a]) and has never appeared in an official release. check-in: e447b23c user: drh tags: trunk | |
| 00:18 | Add the built-in affinity() SQL function. check-in: 57e40e1c user: drh tags: affinity-sql-func | |

| 21:32 | Combine the implementations of the ".tables" and ".indexes" commands in the command-line shell. The ".indexes" command now puts the indexes in multiple columns, just like ".tables" and shows all indexes in all attached databases. check-in: def29333 user: drh tags: trunk | |
| 19:37 | The schema name "main" is always an acceptable alias for the primary database even if the primary database is renamed using SQLITE_DBCONFIG_MAINDBNAME. check-in: 2f481b85 user: drh tags: trunk | |
| 18:18 | Change the output format of the ".databases" command in the command-line shell so that it shows the schema name, a colon, and the corresponding filename. check-in: 8558512e user: drh tags: trunk | |

| ||
| 21:26 | Change the default lookaside configuration from 500 slots of 128 bytes each to 125 slots of 512 bytes each. This uses the same amount of memory (64,000 bytes) but seems to perform much better in test applications. check-in: 52a12e47 user: drh tags: trunk | |
| 19:45 | Simplifications to the way UnpackedRecord objects are allocated. Smaller and faster code that also fixes a subtle (currently unreachable) bug. check-in: f7ab01f2 user: drh tags: trunk | |
|
2016-12-18
| ||
| 17:42 | Change the OP_IfNotZero opcode so that it decrements register P1 by 1 rather than the value in P3, and so that it only decrements if originally positive. This avoids decrementing the smallest 64-bit signed integer. check-in: 165c0446 user: drh tags: trunk | |

2016-12-17
| ||
| 21:07 | Refinements to the new dbfuzz test program. check-in: 50325abe user: drh tags: trunk | |

| 08:18 | Fix a problem in the shell tools readfile() command causing blobs to be truncated at the first embedded 0x00 byte in release builds, or an assert() to fail in a debug build. check-in: 8dedd6ad user: dan tags: trunk | |
