| 17:25 | For a table on the rhs of a LEFT JOIN operator, do not include terms like "IS NULL" from the WHERE clause in the cursor-hint. These may be false for rows that the cursor would otherwise visit, but true for a row of all NULL values generated by the LEFT JOIN. (check-in: 913e595615 user: dan tags: trunk) | |
| 17:22 | Allow LIKE operators that appear in a WHERE clause to be included in the cursor-hint for a cursor on the rhs of a LEFT JOIN. (Closed-Leaf check-in: 7455d932f5 user: dan tags: cursor-hints) | |

| ||
| 18:07 | Prefer to use partial indexes for full table scans when that is possible. (check-in: fe1874321b user: drh tags: trunk) | |
| 14:04 | Add the "dbhash.exe" utility program that computes a SHA1 hash over the invariant content of an SQLite database file. Free space in the file, the page size, auto_vacuum status, text encoding, and so forth do not change the hash. Only the content matters. (check-in: f48a4ad33e user: drh tags: trunk) | |
| 13:59 | Fix an undersized buffer in the SHA1 implementation. (Closed-Leaf check-in: fb2768154c user: drh tags: dbhash) | |

| 20:27 | Translate filenames of the form "/c:/*" into just "c:/*" on WinRT and Cygwin. (SQLite has long done this for Win32/WinNT.) (check-in: f8470ffc49 user: drh tags: trunk) | |
| 18:17 | Fix lempar.c so that the shift-reduce optimization works for error processing. This is a Lemon issue only and has no impact on SQLite. (check-in: 3665a2f554 user: drh tags: trunk) | |

| 01:48 | Small performance improvement in the LIKE function. (check-in: 5fb0c35459 user: drh tags: trunk) | |
| 01:14 | Btree interface refactoring: (1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey() and modified to work only for table btrees with a rowid. (2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize() and modified to work with any btree. (3) The sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() routines are combined into a single sqlite3BtreePayloadFetch() routine. The result of these changes is a smaller binary and fewer CPU cycles needed to run queries. (check-in: 2d831074cf user: drh tags: trunk) | |

| 20:37 | Change the sqlite3BtreeKeySize() interface into sqlite3BtreeIntegerKey() and make it only work for table btrees. Change sqlite3BtreeDataSize() into sqlite3BtreePayloadSize() and make it work for all btrees. Combine sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() into a single sqlite3BtreePayloadFetch() routine. These changes seem to make the b-tree interface more rational and they reduce both binary size and CPU usage. (check-in: bef35e18dd user: drh tags: btree-refactor) | |
| 17:12 | Allocate KeyInfo objects from lookaside if possible. (check-in: b411107a36 user: drh tags: trunk) | |

| 01:01 | Performance optimizations on the CSV virtual table. Disallow WITHOUT ROWID virtual tables that have an xUpdate method, for now. (check-in: 3134b3266c user: drh tags: without-rowid-vtab) | |
|
2016-06-02

|
2016-05-31
| ||
| 21:18 | An experimental branch with code that allows virtual tables to be declared as WITHOUT ROWID tables. This might be useful for virtual tables that model external data sources that do not have a convenient way of computing a unique rowid. The current check-in almost works, but there are still serious issues. (check-in: 49638f180e user: drh tags: without-rowid-vtab) | |
