Changes In Branch IN-operator-improvements Excluding Merge-Ins

| 19:16 | Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. (check-in: 95286821 user: drh tags: trunk) | |
| 11:04 | Rename the internal Schema.flags field to Schema.schemaFlags. (check-in: 5ae80b3c user: drh tags: trunk) | |
| 00:53 | Improved VdbeCoverage() macros. A few minor simplifications to generated VDBE code. (Closed-Leaf check-in: 01f60027 user: drh tags: IN-operator-improvements) | |

| 21:26 | Part of the change in the previous check-in was incorrect and can result in an incorrect UPDATE for WITHOUT ROWID tables. This check-in fixes the problem. (check-in: ee5f6eae user: drh tags: IN-operator-improvements) | |
| 15:12 | Changed my mind: This opcode name changes mere creates unnecessary diff marks between older and newer versions without significantly improving readability. Was: Rename the IsNull opcode to IfNull and rename the NotNull opcode to IfNotNull. (Closed-Leaf check-in: 2f724cba user: drh tags: deadend) | |

2014-08-02
| ||
| 21:03 | Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. (check-in: 436e8842 user: drh tags: IN-operator-improvements) | |
| 20:44 | Remove (newly) incorrect preprocessor check to fix build on WinRT. (check-in: ba782654 user: mistachkin tags: trunk) | |
|
2014-08-01
| ||
| 21:12 | A better comment on the generated code for the NULL-in-RHS-of-IN detection logic. (check-in: 9bc1c730 user: drh tags: trunk) | |
