22:37 | Add an assert() and five testcase() macros to the OP_Cast opcode implementation to help verify that it is fully tested. (check-in: af364cce9d user: drh tags: trunk) | |
21:11 | Minor changes to the CAST logic to make it more testable. (check-in: 1ad70ec550 user: drh tags: trunk) | |
20:21 | Test cases added for using unary "+" and CAST operators on the RHS of range constraints and verifying that STAT3/4 can use those constraints. (check-in: 42505e5a81 user: drh tags: trunk) | |
