Toro 0.7 Released

Just released, a free O’Reilly book on Reactive Microsystems: The Evolution of Microservices at Scale. Brought to you in partnership with Lightbend.

I've just released version 0.7 of Toro. Toro provides semaphores, locks, events, conditions, and queues for Tornado coroutines. It enables advanced coordination among coroutines, similar to what you do in a multithreaded application. Get the latest version with "pip install --upgrade toro". Toro'sdocumentation, with plenty of examples, is on ReadTheDocs.

There is one bugfix in this release. Semaphore.wait() is supposed to wait until the semaphore can be acquired again:

@gen.coroutine
def coro():
    sem = toro.Semaphore(1)
    assert not sem.locked()

    # A semaphore with initial value of 1 can be acquired once,
    # then it's locked.
    sem.acquire()
    assert sem.locked()

    # Wait for another coroutine to release the semaphore.
    yield sem.wait()

... however, there was a bug and the semaphore didn't mark itself "locked" when it was acquired, so "wait" always returned immediately. I'm grateful to"abing" on GitHub for noticing the bug and contributing a fix.
