7 check-ins related to "uninit-vdbe-mem"

2011-12-09

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: 0064bab7 user: drh tags: trunk)
17:51
Remove an unnecessary condition. (Closed-Leaf check-in: d9ba023c user: drh tags: uninit-vdbe-mem)
17:38
Remove an unnecessary initialization of Vdbe.aOnceFlag. (check-in: 421714da user: drh tags: uninit-vdbe-mem)
17:27
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: 6a9fb47d user: drh tags: uninit-vdbe-mem)
16:59
Previous check-in broke auto-increment. This check-in appears to fix it. (check-in: 28ffd39c user: drh tags: uninit-vdbe-mem)
16:21
Make no assumptions about the initial state of VDBE registers. (check-in: 521d72bd user: drh tags: uninit-vdbe-mem)
13:24
Modify the OP_Once opcode so that it works correctly in trigger sub-programs. This is a candidate fix for [7bbfb7d442]. (check-in: 557c6905 user: dan tags: trunk)
