| 18:22 | Disable the table selection rule that tried to prevent full table scans from migrating to the outer loop unless they were optimal. The new scaling of outer-loop costs by cost of inner loops obviates the need for that step. And, in fact, that step causes problems with the new inner-loop cost accounting. (Closed-Leaf check-in: 51bfd63b user: drh tags: inner-loop-cost) | |
| 17:59 | Try to take into account the cost of inner loops when selecting which table of a join to use for the outer loop. (check-in: 94255634 user: drh tags: inner-loop-cost) | |

| 19:25 | Fix a bug in fts3 causing it to return SQLITE_NOMEM when NEAR, OR and some auxiliary functions were used together. Also a segfault in vtab.c that could follow an OOM condition. (check-in: 33f4f981 user: dan tags: trunk) | |
| 15:43 | Fix typo in usage text for the command-line shell. Also, in the same usage text, make the file name argument to -init uppercase for consistency. (check-in: a6d906cf user: mistachkin tags: trunk) | |
| 15:23 | Improvements to the command-line argument parsing in the command-line shell. Command-line options can now occur either before or after the database name and first command and are still accepted and processed. Command-line options are processed even if no database name is given (and :memory: is assumed). (check-in: 317c80cb user: drh tags: trunk) | |

| 23:16 | Ensure that when the source of a backup is a database that is zero bytes in size, the final destination database consists of at least one page. Truncating it to zero bytes is equivalent to zeroing the schema cookie and change counter, which can cause problems for existing clients. (check-in: ca86138b user: drh tags: trunk) | |

(check-in: 956e4d7f user: drh tags: trunk) | |

| 15:19 | More lenient handling of ORDER BY optimization in joins with mixed ASC/DESC. This is a better and less restrictive fix for the problem addressed by the previous check-in. (check-in: abcf6a5d user: drh tags: trunk) | |
| 14:11 | Only continue an ORDER BY optimization into inner loops if the equality constraints on the inner loop match terms of an outer ordered index that are actually used by the ORDER BY clause. (check-in: b0e7b4df user: drh tags: trunk) | |
| 01:46 | Factor an invariant out the loop termination condition for the ORDER BY satisfied-by-index analyzer routine. (check-in: 545bb336 user: drh tags: trunk) | |

| 12:16 | Make sure the size parameter to read and write VFS methods in the unix VFS do not become too big or go negative. This was not actually possible in the current code. The checks are added to make sure some future bug does not make it possible. (check-in: daebe3bd user: drh tags: trunk) | |
| 06:50 | Ensure that the value returned by xSectorSize() is reasonable (currently defined as between 2^5 and 2^16 bytes) before using it to calculate the amount of padding to add to a wal file. (check-in: 6b4ff83b user: dan tags: trunk) | |

| 20:23 | Avoid calling sqlite3BtreeEnter() in a corner case where the corresponding database handle mutex (sqlite3.mutex) may not be held. This prevents a potential deadlock or crash that can occur if the backup API, shared-cache mode and SQLITE_HAVE_CODEC are all in use. (check-in: 89b8c377 user: dan tags: trunk) | |
