Update: ok I believe I've corrected the issue, though the behavior is as it was before, I'm wondering if this is the right behavior @yperess Imagine I have 3 chained submissions and cancel the one in the middle before submit is called, the first one should report success, the next two should be cancelled, should they report anything? I guess more critically, why is cancelling before submit a special case, can you help clarify this @yperess? Thanks! |
Callbacks were a bit neglected in terms of test coverage, especially when used in chains. It was clear from the code that chained callbacks may not actually work, and callback ordering then was hard to verify. Test callbacks chained to transactions work as expected. The test iodev had built up some cruft over time and in the process showed a few bugs once callback chaining was fixed so the test iodev now better matches typical iodev implementations at this point. Cancellation testing now includes an added case for cancelling a the second submission in the chain prior to calling submit noting that no completions notifications should be given back for those.
