| 20:46 | Readability improvements to the Win32 RC file. (check-in: e6459062 user: mistachkin tags: trunk) | |
| 19:27 | Minor consistency fixes to the Win32 RC file. (check-in: 619c5211 user: mistachkin tags: trunk) | |
| 12:57 | The date and time functions use the exact same notion of "now" for every invocation within the same call to sqlite3_step(). (check-in: daf6ba41 user: drh tags: trunk) | |

| ||
| 23:27 | Fix Windows SDK compiler warning. (check-in: d5fc3f1d user: mistachkin tags: trunk) | |
| 23:26 | Fix test issues for Windows portability. (check-in: 650b3282 user: mistachkin tags: trunk) | |
| 22:38 | VSIX tooling changes to support Visual Studio 2013. (check-in: d56fac40 user: mistachkin tags: trunk) | |
| 21:03 | Fix the "const" qualifiers on the pragma name table. (check-in: b74e6be8 user: drh tags: trunk) | |
| 21:01 | Add the soft_heap_limit pragma. (check-in: c326356f user: drh tags: trunk) | |
| 19:00 | Tweak the new PRAGMA name parser to achieve full branch test coverage. (check-in: c82e05c4 user: drh tags: trunk) | |
| 18:15 | Remove one unreachable branch and add asserts() to dupedExprStructSize(). New asserts verify that removed branch is unused and that constants that are ORed together in the output do not overlap. (check-in: 86ad358b user: drh tags: trunk) | |
| 17:47 | Adjust the query planner to take into account WHERE clause terms that do not drive indices. Add the unlikely() and likelihood() functions used to give hints to the query planner about the selectivity of WHERE clause terms. (check-in: bc446449 user: drh tags: trunk) | |
| 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) | |

| 23:42 | Refactor the ExprSetIrreducible() macro into ExprSetVVAProperty(*,EP_NoReduce). This is a naming change only. The logic is the same. (Closed-Leaf check-in: 695aee46 user: drh tags: unlikely-func) | |
| 23:12 | Fix typo in a macro name: "GlogUpperToLower" should be "GlobUpperToLower" (check-in: 73634ca4 user: drh tags: trunk) | |
| 17:29 | Merge in the Expr.flags expansion to 32-bits. Use an extra bit to help optimize the sqlite3ExprSkipCollate() routine. (check-in: 4c84d1b4 user: drh tags: unlikely-func) | |
| 16:50 | Increase the number of bits available in Expr.flags. Other tweaks aimed at making expression processing more robust. (Closed-Leaf check-in: 579a5125 user: drh tags: expr-tuning) | |
| 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) | |
|
2013-09-09
| ||
| 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) | |
|
2013-09-07
| ||
| 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) | |
|
2013-09-06
| ||
| 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) | |
