2019-10-05
19:53
Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis.

19:24
Optimization to sqlite3VtabUnlockList() for the common case when there is no work to do. check-in: fc8d4508 user: drh tags: trunk

2019-10-03
16:02
Avoid running a couple of tests in affinity2.test as part of the valgrind permutations, as the way floating point computations are simulated by valgrind causes them to fail. check-in: 7f9a4b60 user: dan tags: trunk

Alternative implementation of the previous check-in which is testable. check-in: 102ef644 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: 6a204b19 user: drh tags: trunk
2019-09-26

2019-09-17
