| 18:23 | Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. (check-in: d01cedaa user: drh tags: trunk) | |
| 18:21 | Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. (Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e) | |

| 15:22 | Modify the way the costs of various query plans are estimated. If the user supplies a likelihood() value (or equivalent) on an indexed WHERE constraint, use it to estimate the number of index rows visited. (check-in: 90e36676 user: dan tags: trunk) | |
| 15:00 | Add text to the header comment of whereLoopAddBtree() describing how the costs of various b-tree loops are estimated. (Closed-Leaf check-in: 05e6e16c user: dan tags: experimental-costs) | |

| 19:34 | The trunk assumes that an open range constraint on an indexed term (col>?) term matches 1/4 of the indexed rows, and that a closed constraint (col BETWEEN ? AND ?) matches 1/64. Change this branch to do the same. (check-in: 4047ac75 user: dan tags: experimental-costs) | |

| 15:11 | Update unordered.test to take into account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 20f468df user: dan tags: experimental-costs) | |
| 12:08 | Add an extra column to a table in analyze9.test to give the planner a little more reason to select an index. (check-in: 1b95544f user: dan tags: experimental-costs) | |
| 10:00 | Update test script analyze3.test to account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 35f46a55 user: dan tags: experimental-costs) | |
| 09:35 | Modify internal function whereLoopAdjustCost() so that it does not prefer a skip-scan over a regular index scan even if the regular scan uses a subset of the WHERE terms used by the skip-scan. (check-in: 88a5758d user: dan tags: experimental-costs) | |

| 14:42 | Make sure ORDER BY clauses on joins that involve virtual tables and that have a DISTINCT clause work correctly. This is a candidate fix for ticket [388d01d4bb8f9]. Test cases for that ticket will be checked in separately. (check-in: 17113812 user: drh tags: trunk) | |
| 12:35 | When VDBE_PROFILE is enabled, ignore negative opcode times, which sometimes occur, perhaps due to context swaps. (check-in: 4e88042f user: drh tags: trunk) | |
