      Implement 'Canceler' for managing side-band promise cancelation. · 0df23c4f
      Kenton Varda authored
      This is necessary when someone other than the promise owner might need to destroy the state a promise is operating on. It comes up when implementing pumpTo() for userland pipes -- cancelling the pump needs to cancel any writes currently passing through the pipe.

      Add WaitScope::poll() and Promise::poll() to pump all events. · ece2a1aa
      Kenton Varda authored
      These are useful in unit tests. Often, some tasks have been queued, and we want to test that a particular thing happens or doesn't happen as a result of those tasks, without actually waiting on any specific promise. We need a way to run the event queue until it is empty. For that, we add WaitScope::poll().
      
      Or, sometimes, we want to check if a specific promise is (or is not!) resolved as a result of the tasks that have been queued so far, but we may not want to actulaly wait() on it for a couple reasons:
      - We may actually want to verify that the promise is *not* resolved by tasks so far. wait()ing on it would be expected to deadlock.
      - We may expect the promise to resolve, but would prefer not to deadlock if it doesn't resolve (we'd rather fail fast).
      
      For this, we add Promise::poll().
      
      There are lots of tests I've written which could be simplified by this, but for now I'm not refactoring any existing tests.
      
      Note that adding these (particularly Promise::poll()) required updating the async framework a bit, in that this is the first case where PromiseNode::onReady() might be called multiple times, or might be canceled without destroying the PromiseNode entirely. Luckily this was not hard to account for. (We still have the rule that get() can only be called once, though.)

      Change license to MIT. · 889204fe

      The license change is practically meaningless, as MIT and BSD 2-clause are legally equivalent. However, the BSD 2-clause license is sometimes confused for its ugly siblings, BSD 3-clause and BSD 4-clause. The MIT license is more immediately recognizeable for what it is.
      
      Rémy Blank and Jason Choy (the two non-trivial contributors) are on record as approving this change:

      Revamp concurrency model, part 1: EventLoop no longer allows cross-thread event… · 7921c854
      Kenton Varda authored
      Revamp concurrency model, part 1:  EventLoop no longer allows cross-thread event queuing, simplifying many things.  Capability clients are no longer thread-safe, so they don't have to be so const.  In the future, explicit ways to communicate between threads will be re-added, but threads will be treated more like separate vats that just happen to have a particularly fat pipe.  Upcoming:  Remove mutexes.
