| 16:56 | Enhance the pragma lookup table generator script to output a comment that gives the number of pragmas. (check-in: ca052050 user: drh tags: trunk) | |
| 16:36 | Change the PRAGMA parser to use a binary search for the pragma name. Also: Minor performance enhancement to sqlite3DbFree() and to the token dequoter. (check-in: 870c030b user: drh tags: trunk) | |
| 12:10 | Add tests for the fts4 unicode61 tokenchars and separators options. (check-in: 9ce6f40d user: dan tags: trunk) | |

| 23:12 | Fix typo in a macro name: "GlogUpperToLower" should be "GlobUpperToLower" (check-in: 73634ca4 user: drh tags: trunk) | |
| 02:09 | For error log messages generated by the Win32 native allocator, make sure the correct format specifier is used for the value returned by GetLastError(). (check-in: 75a8a8c1 user: mistachkin tags: trunk) | |
| 01:47 | Fix a couple more harmless compiler warnings. (check-in: 59708674 user: mistachkin tags: trunk) | |
| 01:33 | Remove two obsolete fields from the sqlite3 object. (check-in: 117fa5fb user: drh tags: trunk) | |
| 00:54 | Fix harmless compiler warning. (check-in: 2b510614 user: mistachkin tags: trunk) | |
| 00:40 | Merge updates from trunk. (Closed-Leaf check-in: fca799f0 user: mistachkin tags: vsix2013) | |

| 17:39 | Improvements to likelihood processing so that commuting an unindexed term in the WHERE clause does not change the query plan. (check-in: 6e6bded0 user: drh tags: unlikely-func) | |
| 14:57 | Add test cases to cover TPC-H Q8. (check-in: eb5cef83 user: drh tags: trunk) | |
| 14:34 | Additional unlikely() test cases. Logic tweaks to support test coverage. (check-in: 5d00cce7 user: drh tags: unlikely-func) | |
| 11:38 | Change the name of the two-argument unlikely() function to likelihood(). Add test cases. (check-in: 29a359b8 user: drh tags: unlikely-func) | |
| 03:53 | Tweaks to the index selection logic. (check-in: 52d52688 user: drh tags: unlikely-func) | |

| 01:53 | Merge trunk fixes into the unlikely-func branch. (check-in: a51d7515 user: drh tags: unlikely-func) | |
| 01:41 | Deterministically initialize the PRNG used as a tie-breaker in the ANALYZE command, so that the analysis is always the same given the same database. This simplifies testing. (check-in: 48ed8b56 user: drh tags: trunk) | |
|

| 19:37 | Make sure that the transitive constraint optimization does not cause WHERE clause terms to be disabled prematurely. We are unable to find a test case that fails because of this, but it seems prudent to make this preventative change nevertheless. (check-in: d6e361d7 user: drh tags: trunk) | |

| ||
| 00:29 | Continuing refinements of the logic to take WHERE clause terms not used for indexing into account when computing the number of output rows from each table. (check-in: b65dc534 user: drh tags: unlikely-func) | |
|

| ||
| 22:27 | Merge updates from trunk. (check-in: 8922be1a user: mistachkin tags: toTypeFuncs) | |
| 17:45 | Enhance the plan solver to take into account the number of output rows when computing the set of paths to retain for the next cycle. (check-in: 1a46a724 user: drh tags: unlikely-func) | |
| 15:23 | Initial implementation of the unlikely() SQL function used as a hint to the query planner. (check-in: 036fc37a user: drh tags: unlikely-func) | |
| 13:10 | Combine the FuncDef.iPrefEnc and FuncDef.flags fields into a single new FuncDef.funcFlags field. (check-in: 97b10e66 user: drh tags: trunk) | |
