16:33 | Allow compile-time options -DHAVE_GETHOSTUUID=0 and -DHAVE_GETHOSTUUID=1. (check-in: 3bcb9cc104 user: drh tags: trunk) | |
15:15 | Alternative implementation of the previous check-in which is testable. (check-in: 102ef64462 user: drh tags: trunk) | |
15:01 | Fix sqlite3ExprCompare() so that it ignores differences in the Expr.iTable field for IN operators, as otherwise it can lead to false negatives, which is usually harmless, but can cause problems for an assert() in the window function logic. (check-in: 6a204b192a user: drh tags: trunk) | |
