| 16:05 | Quick patch to the Lemon parser template to avoid an array overread reported by OSSFuzz. A proper fix involves enhancements to the table generators in Lemon to make the overread impossible. That fix will take longer to implement. The current check-in is a stop-gap. (check-in: 3f6730be user: drh tags: trunk) | |

2018-06-08
| ||
| 23:23 | When the query planner has the opportunity to use an IN operater constraint on a term of an index other than the left-most term, use the estimated number of elements on the right-hand side of the IN operator to determine if makes sense to use the IN operator with index lookups, or to just do a scan over the range of the table identified by the index terms to the left. Only do this if sqlite_stat1 measurements are available as otherwise the performance estimates will not be accurate enough to discern the best plan. Bias the decision slightly in favor of using index lookups on each element of the IN operator. (check-in: 2cbbabdf user: drh tags: trunk) | |
| 21:21 | Only choose to scan an IN operator rather than use an index if we have real STAT1 data to suggest it is advantageous. (Closed-Leaf check-in: 30e87466 user: drh tags: in-scan-vs-index) | |

| 18:13 | The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value.

| 23:51 | When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate.
