Change the VDBE so that all registers are initialized to "Invalid" instead of NULL and report errors on any attempted read of an Invalid register. This will help prevent future bugs similar to [7bbfb7d442]. check-in: 0064bab771 user: drh tags: trunk

Remove an unnecessary condition. Closed-Leaf check-in: d9ba023c60 user: drh tags: uninit-vdbe-mem

Remove an unnecessary initialization of Vdbe.aOnceFlag. check-in: 421714dad3 user: drh tags: uninit-vdbe-mem

Take out the OP_JumpOnce opcode. Revert compound SELECT to use OP_IfNot, which is the correct behavior. Mark trigger registers as initially invalid. check-in: 6a9fb47d50 user: drh tags: uninit-vdbe-mem

Previous check-in broke auto-increment. This check-in appears to fix it. check-in: 28ffd39c71 user: drh tags: uninit-vdbe-mem
16:21
Make no assumptions about the initial state of VDBE registers. check-in: 521d72bdf6 user: drh tags: uninit-vdbe-mem

Modify the OP_Once opcode so that it works correctly in trigger sub-programs. This is a candidate fix for [7bbfb7d442]. check-in: 557c69055a user: dan tags: trunk
