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: 4047ac75e2 user: dan tags: experimental-costs) | |
17:56 | Add the sqlite3_rtree_query_callback() API to the RTree virtual table. (Cherrypick from the sessions branch.) (check-in: af2cbe64ad user: drh tags: trunk) | |
17:51 | Add the sqlite3_rtree_query_callback() API to the RTree virtual table. (check-in: 3dca280935 user: drh tags: sessions) | |
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: 20f468dfbc 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: 1b95544f84 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: 35f46a55d8 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: 88a5758dcc user: dan tags: experimental-costs) | |
08:49 | Fix an error in estimating of the number of rows visited by a range scan. (check-in: d491de62fc user: dan tags: experimental-costs) | |

20:22 | If the user provides likelihood() data for a WHERE clause term used as part of an index key, have the planner use it when calculating the expected number of rows visited by the loop. (check-in: c51efaa5d2 user: dan tags: experimental-costs) | |
17:37 | Add test cases to ensure correct operation of joins with a virtual table that include DISTINCT and ORDER BY clauses. Verification for ticket [388d01d4bb8f9]. (check-in: 5ada136f43 user: drh tags: trunk) | |
15:01 | Store values loaded from the stat1 table as logarithmic values in memory. (check-in: 1bd74c49dd 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: 1711381226 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: 4e88042f9d user: drh tags: trunk) | |

13:36 | Comment tweaks on the test case for the [b75a9ca6b0] bug fix. (check-in: 65d2544af9 user: drh tags: trunk) | |
13:21 | Avoid discarding an ORDER BY clause in the case where an identical GROUP BY clauses uses an index to group, but not sort, the rows. Fix for [b75a9ca6b0]. (check-in: de9a490f59 user: dan tags: trunk) | |
2014-04-18
| ||
22:20 | Clean up the proper-subset cost adjustment logic to make it more compact and easier to read and so that full branch test coverage is more easily obtained. (check-in: 9a5d38c79d user: drh tags: trunk) | |
00:49 | Add the SQLITE_RUNTIME_BYTEORDER compile-time option to force SQLite to check the processor byte-order at run-time. Add additional compile-time byte order checks for ARM, PPC, and SPARC. (check-in: 2c5363873a user: drh tags: trunk) | |
00:06 | Add the SQLITE_TESTCTRL_BYTEORDER test control to interrogate SQLite's notion of the processor byte order and whether the byte order is known at compile-time or determined at run-time. (check-in: 9c6961967a user: drh tags: trunk) | |
