2016-09-26
| ||
14:39 | When flattening a query of the form "SELECT * FROM (SELECT * FROM tbl WHERE x=?) WHERE y=?", ensure that the final WHERE clause is "x=? AND y=?" instead of "y=? AND x=?". Although it is still not guaranteed, this makes the order in which WHERE clause terms are processed comport more closely to users expectations. (check-in: cf7f9e6d user: dan tags: trunk) | |
12:38 | Inline the relevent parts of sqlite3ExprAlloc() into spanExpr(), for a performance improvement. (check-in: fe89225e user: drh tags: trunk) | |

20:59 | Use sqlite3ExprAlloc() instead of sqlite3PExpr() for leaf nodes in the expression tree, where appropriate. This is both smaller and faster. (check-in: afac0709 user: drh tags: trunk) | |
18:13 | New test case for the ORDER BY LIMIT optimization. (check-in: 9a5a489d user: drh tags: trunk) | |
18:06 | Fix the ORDER BY LIMIT optimization backport so that it works when the ORDER BY uses the DESC direction. (check-in: 0c3cafb7 user: drh tags: branch-3.8.9) | |
2016-09-22
| ||

18:53 | Remove the internal sqlite3CodeOnce() interface, replacing it with a direct call to sqlite3VdbeAddOp0(v,OP_Once). Slightly smaller and faster. (check-in: c3774c6a user: drh tags: trunk) | |
18:46 | Makefile changes to support building winsqlite3.dll using STDCALL rather than CDECL. (check-in: 5e892d60 user: mistachkin tags: trunk) | |

19:00 | Do not run vacuummem.test if ENABLE_MEMORY_MANAGEMENT is defined. (check-in: 4a613d85 user: dan tags: trunk) | |
18:18 | Fix obsolete requirements marks. Add new tests for VACUUM of attached databases. (check-in: 2b44f9aa user: drh tags: trunk) | |
17:53 | Avoid running vacuum5.test in auto-vacuum mode. (check-in: be184bef user: dan tags: trunk) | |
17:47 | Do not run test "delete_db.test" with either the journaltest or inmemoryjournal permutations. Ensure that the multiplexor tests in delete_db.test are performed in non-autovacuum mode. (check-in: 46b7d19e user: dan tags: trunk) | |
14:41 | Update the fts5vocab table to handle "ORDER BY term" efficiently. (check-in: d4928fb5 user: dan tags: trunk) | |

11:00 | Fix a segfault introduced by the row-value enhancement that comes up on a skip-scan where the first term of the index is unconstrained and the second term is of the form "columm IN (SELECT...)". (check-in: 2401ea5a user: drh tags: trunk) | |
10:24 | Improved performance in sqlite3ExprCodeTarget(). (check-in: 75146165 user: drh tags: trunk) | |
