The "COLLATE binary" that was being added to the RHS of IN was overriding the implicit collating sequence of the LHS. This change defines the EP_Generic expression node property that blocks all affinity or collating sequence information in the expression subtree and adds that property to the expression taken from RHS of the IN operator.

| 23:35 | Do not allow cursor hints to use expressions containing subqueries. This change fixes the problem seen in the previous check-in. (check-in: bfefc57554 user: drh tags: cursor-hints) | |
| 20:39 | If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the sqlite3BtreeCursorHint() interface to provide hints to the storage engine about rows that need not be returned. Hints can be disabled using SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000). Cursor hints are not used by the built-in storage engine of SQLite but might be useful to applications that provide their own storage engine. The current code is work-in-progrss and contains bugs.

Writing to a moved or renamed database is still allowed when journal_mode is OFF or MEMORY. (check-in: 369a23e006 user: drh tags: trunk) | |

| 17:23 | Only error out on a database file move when attempting to start a write transaction. Assume read transactions are still safe. And make the error SQLITE_READONLY_DBMOVED instead of SQLITE_IOERR_NODB. (check-in: 28348f2ada user: drh tags: detect-moved-db) | |

2013-11-26

| 23:27 | Make sure the update hook is not invoked for WITHOUT ROWID tables, as the documentation specifies. This bug was found while adding requirements marks, so a few extraneous requirements marks are included in this check-in. (check-in: 0978bac6b8 user: drh tags: trunk) | |
| 22:46 | Add requirements test cases for determining when an expression is true and when it is false. (check-in: 838654e563 user: drh tags: trunk) | |
| 21:18 | Changing the CAST behavior of REAL values actually changed a documented requirement. So we also have to change the requirement evidence text to match. (check-in: d84aa44e39 user: drh tags: trunk) | |

| 15:45 | Change the REAL-to-INTEGER casting behavior so that if the REAL value is greater than 9223372036854775807.0 then it is cast to the latest possible integer, 9223372036854775807. This is sensible and the way most platforms work in hardware. The former behavior was that oversize REALs would be cast to the smallest possible integer, -9223372036854775808, which is the way Intel hardware works.

| 22:24 | Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add an assert() to verify that the do-loop really is appropriate. This gives about a 10% performance boost in that routine, or a 0.9% boost overall. (check-in: 011a6be439 user: drh tags: trunk) | |
| 21:49 | Clarify docs for the SQLITE_CONFIG_WIN32_HEAPSIZE option. (Closed-Leaf check-in: 51e876074a user: mistachkin tags: winHeapSize) | |
| 21:41 | Remove a NEVER() from a branch that is now reachable during OOM faults. (check-in: 18bdcb05c2 user: drh tags: trunk) | |
| 20:50 | Optimizations to the sqlite3BtreeMovetoUnpacked() routine in storage engine making it about 17.8% faster, which in turn makes SQLite over 1.2% faster overall. (check-in: 032e89934f user: drh tags: trunk) | |
| 20:14 | Return an SQLITE_CORRUPT error if the content size field of a table record extends off the end of a page. (Closed-Leaf check-in: b48c4e4021 user: drh tags: btree-optimization) | |

|
2013-11-23
| ||
| 22:45 | A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however. (Closed-Leaf check-in: 8191b51212 user: drh tags: memsys5-performance) | |

Opcodes are reordered in mkopcodesh.awk to put the switched opcodes close together, for additional performance and to reduce code footprint. (check-in: 924f7e4d7a user: drh tags: trunk) | |

| 19:11 | Factor all KeyInfo object allocations into a single function: sqlite3KeyInfoAlloc(). Always allocate enough space so that sqlite3VdbeRecordCompare() can avoid checking boundaries and hence run faster. (check-in: 7301bedd94 user: drh tags: trunk) | |

| 15:32 | Improve performance of sqlite3VdbeRecordCompare() by using an approximation that might give false negatives and only running the more expensive exact subexpression if the approximation fails. (check-in: 28979dcd16 user: drh tags: trunk) | |

| 20:26 | Fix a potential buffer overread in sqlite3VdbeRecordCompare() when a serial_type specifies a field that starts in bounds but is much too large for the allocated buffer. Mostly harmless. The overread is unlikely to go more than one or two bytes past the end of the buffer. (check-in: e436b2f4e5 user: drh tags: trunk) | |

| 17:21 | An improved method for avoiding the use of the STAT3 samples to compute the estimated number of outputs when the left-most index is equality constrained. This check-in undoes the previous fix and applies a new one. (check-in: 127a5b776d user: drh tags: trunk) | |

| 23:22 | Add logic to the query planner to only use partial indices if the WHERE clause constrains the search to rows covered by the partial index. This is just infrastructure. The key routine, sqlite3ExprImpliesExpr(), is currently a no-op so that partial indices will never be used. (check-in: 8ca3eac111 user: drh tags: partial-indices) | |
