Bug Description

I have managed to get a wheel of python_qpid_proton which is not linked against the SASL libraries. TestCyrusAuthentication does not detect this and attempts to run anyway, which fails. If possible, TestCyrusAuthentication should test that SASL authentication is available, and skip the tests if it is not.

Fix reconnection when heartbeat is missed

    When a heartbeat is missing we call ensure_connection()
    that runs a dummy method to trigger the reconnection
    code in kombu. But also the code is triggered only if the
    channel is None.

In case of the heartbeat threads we didn't reset the channel
before reconnecting, so the dummy method doesn't do anything.

This change sets the channel to None to ensure the connection
is reestablished before the dummy method is run.

Also it replaces the dummy method by checking the kombu connection
object. So we are sure the connection is reestablished.

notif: Check the driver features in dispatcher
    
    The transport/driver features check is done into the get listener
    methods.
    So when these methods are not used the driver features checks is not
    done.
    
    This change moves it into the dispatcher layer to ensure the
    requirements are always checked.
    
    This changes a bit the behavior of when the check occurs. Before
    it was during the listener object initialisation. Now this
    when the listener server start.

batch notification listener
    
    Gnocchi performs better if measurements are write in batch
    When Ceilometer is used with Gnocchi, this is not possible.
    
    This change introduce a new notification listener that allows that.
    
    On the driver side, a default batch implementation is provided.
    It's just call the legacy poll method many times.
    
    Driver can override it to provide a better implementation.
    For example, kafka handles batch natively and take benefit of this.

default of kombu_missing_consumer_retry_timeout
    
    This change the default of kombu_missing_consumer_retry_timeout
    
    The initial value of 60 seconds, have been chosen because the default
    rpc_response_timeout is 60. That means, the client doesn't wait for
    its reply after rpc_response_timeout is reach, so we don't need
    to retry it send it its reply more than rpc_response_timeout.
    
    But the real intent of kombu_missing_consumer_retry_timeout is
    to mitigate the side effect when the rabbitmq server(s) died/failover/restart.
    
    So the question is more how long we expect the server(s) to come back
    and all the oslo.messaging applications to reconnect.
    
    In that case 60 seconds looks a bit high.
    
    Also this 60 seconds have a sad side effect when we can't send the reply
    when the rpc client is really gone (like nova-compute restart).
    The rabbitmq connection to send the reply is hold during 60 seconds.
    
    I propose 5 seconds because,i n case of failover or restart I expect
    everything because normal in less that 5 seconds.

Don't hold the connection when reply fail
    
    This change moves the reply retry code to upper layer
    to be able to release the connection while we wait between
    two retries.
    
    In the worse scenario, a client waits for more than 30 replies
    and died/restart, the server tries to send this 30 replies to this
    this client and can wait too 60s per replies. During this
    replies for other clients are just stuck.
    
    This change fixes that.

Move ConnectionPool and ConnectionContext outside amqp.py
    
    ConnectionPool and ConnectionContext can be used by other
    drivers (like Kafka) and hence should be outside of amqp.py.
    * Moving ConnectionPool to pool.py
    * Moving ConnectionContext to common.py
    * Moving a couple of global variables to common.py
    
    No other logic changes, just refactoring

Use round robin failover strategy for Kombu driver
    
    Shuffle strategy we use right now leads to increased reconnection time
    and provides no benefit. Sometimes it might lead to RPC operations
    timeout because the strategy provides no guarantee on how long the
    reconnection process will take. See the referenced bug for details.
    
    On the other side, round-robin strategy provides least achievable
    reconnection time. It also provides guarantee that if K of N RabbitMQ
    hosts are alive, it will take at most N - K + 1 attempts to
    successfully reconnect to RabbitMQ cluster.
    
    With shuffle strategy during failover clients connect to random hosts
    and so the load is distributed evenly between alive RabbitMQs.
    But since we shuffle list of hosts before providing it to Kombu, load
    will be distributed evenly with round-robin strategy as well.
    
    DocImpact
    A new configuration option kombu_failover_strategy for Kombu driver is
    added. It determines how the next RabbitMQ node is chosen in case the
    one we are currently connected to becomes unavailable. It takes effect
    only if more than one RabbitMQ node is provided in config. Available
    options are:
    
     * round-robin: each RabbitMQ host in the list is tried in cycle until
       oslo.messaging successfully connects. Since oslo.messaging
       shuffles list of RabbitMQ hosts, the order of hosts in the cycle
       will be random and will not depend on order provided in config.
    
     * shuffle: oslo.messaging selects a random host from the list and
       tries to connect to it. If connection fails, oslo.messaging repeats
       attempt to connect to another random host. Oslo.messaging stops
       once it successfully connects to a host. Note that in each
       iteration a host to connect is selected independently of previous
       iterations, i.e. it might happen that oslo.messaging will try to
       connect to the same host several times in a row.
    
    The option's default value is round-robin. Before the option was
    introduced, the default strategy was shuffle. For the reasoning,
    see the main body of the commit message and the referenced bug.

Provide alias to oslo_messaging.notify._impl_messaging
    
    Ifb96c2ae9868426cac2700bf4917c27c02c90b15 moved the _impl_messaging
    module to oslo_messaging.notify.messaging which breaks neutron.
    
    Neutron is fixed on master for mitaka but neutron on stable/liberty
    is broken, and changing neutron on stable/liberty to use the new
    path would require a global-requirements minimum version bump for
    oslo.messaging to 2.6.0, which we want to avoid for people that have
    already shipped liberty.
    
    So provide an alias to the moved module so neutron in stable/liberty
    continues to work. We deprecate the module so consumers know they
    need to upgrade and move off this. We may need to cap oslo.messaging
    in global-requirements on stable/liberty at some point when we remove
    the deprecated alias module.

Robustify locking in MessageHandlingServer
    
    This change formalises locking in MessageHandlingServer, which closes
    several bugs:
    
    * It adds locking for internal state when using the blocking executor,
      which closes a number of races.
    * It does not hold a lock while executing server functions,
      which removes a potential cause of deadlock if the server does its
      own locking.
    * It fixes a regression introduced in change
      gI3cfbe1bf02d451e379b1dcc23dacb0139c03be76. If multiple threads
      called wait() simultaneously, only 1 of them would wait and the
      others would return immediately, despite message handling not having
      completed.  With this change only 1 will call the underlying wait,
      but all will wait on its completion.
    
    Additionally, it introduces some new functionality:
    
    * It allows the user to make calls in any order and it will ensure,
      with locking, that these will be reordered appropriately.
    * The caller can pass a `timeout` argument to any server method, which
      will cause it to raise an exception if it waits too long.
    * The caller can pass a `log_after` argument to any server method,
      which will cause it to raise a log message if it waits too long. It
      can also be used to disable logging when waiting is intentional.
    
    We remove DummyCondition as it no longer has any users.
    
    This change was originally committed as change
    I9d516b208446963dcd80b75e2d5a2cecb1187efa, but was reverted as it
    caused a hang in a Nova test. This was caused by the locking behaviour
    for handling restarting a previously stopped server. The original
    patch caused the state to 'wrap' immediately after the user called
    wait(). This caused a hang in tests which redundantly called stop()
    and wait() multiple times. This new patch only wraps when the user
    calls start() again. Callers who do not restart a server will
    therefore not be affected by the wrapping behaviour. Callers who do
    restart a server will be no worse than before. We add a deprecation
    warning on restart, as this operation is inherently racy with this api
    and there is a simple, safe alternative.
    
    This new version has been successfully tested against the unit and
    functional tests of nova, cinder, glance, and ceilometer.

Remove a useless statement
    
    This statement is useless since both 'username' and 'password' are set to None
    in the for loop, and that they are not used outside of the loop.
    
    Removing this line also help us getting rid of a false positive thrown by
    bandit.

Robustify locking in MessageHandlingServer
    
    This change formalises locking in MessageHandlingServer. It allows the
    user to make calls in any order and it will ensure, with locking, that
    these will be reordered appropriately. It also adds locking for
    internal state when using the blocking executor, which closes a number
    of races.
    
    It fixes a regression introduced in change
    gI3cfbe1bf02d451e379b1dcc23dacb0139c03be76. If multiple threads called
    wait() simultaneously, only 1 of them would wait and the others would
    return immediately, despite message handling not having completed.
    With this change only 1 will call the underlying wait, but all will
    wait on its completion.
    
    We add a common logging mechanism when waiting too long. Specifically,
    we now log a single message when waiting on any lock for longer than
    30 seconds.
    
    We remove DummyCondition as it no longer has any users.

Modify simulator.py tool
    
    Introduce mechanism of generating real life messages to the tool
    using the information gathered during Rally testing. This change
    allows to generate messages of the specfic length due to the
    distribution observed on real environment.
    
    messages_length.txt file contains lengths of string JSON objects
    that were later sent through the MQ layer during deployment and
    deletion of 50 VMs.
    
    simulator.py was modified to use this data as a baseline to generate
    random string messages of the required length with the needed
    probability.

Fix target resolution mismatch in neutron, nova, heat
    
    Some tempest tests were failing because of NoSuchMethod,
    UnsupportedVersion and other missed endpoint errors.
    
    This fix provides new listener per each target and
    more straight-forward matchmaker target resolution logic.

Use yaml.safe_load instead of yaml.load

Trivial locking cleanup in test_listener
    
    ListenerSetupMixin.ThreadTracker was reading self._received_msgs

Fix a race calling blocking MessageHandlingServer.start()
    
    This fixes a race due to the quirkiness of the blocking executor. The
    blocking executor does not create a separate thread, but is instead
    explicitly executed in the calling thread. Other threads will,
    however, continue to interact with it.
    
    In the non-blocking case, the executor will have done certain
    initialisation in start() before starting a worker thread and
    returning control to the caller. That is, the caller can be sure that
    this initialisation has occurred when control is returned. However, in
    the blocking case, control is never returned. We currently work round
    this by setting self._running to True before executing executor.start,
    and by not doing any locking whatsoever in MessageHandlingServer.
    However, this current means there is a race whereby executor.stop()
    can run before executor.start(). This is fragile and extremely
    difficult to reason about robustly, if not currently broken.
    
    The solution is to split the initialisation from the execution in the
    blocking case. executor.start() is no longer a blocking operation for
    the blocking executor. As for the non-blocking case, executor.start()
    returns as soon as initialisation is complete, indicating that it is
    safe to subsequently call stop(). Actual execution is done explicitly
    via the new execute() method, which blocks.
    
    In doing this, we also make FakeBlockingThread a more complete
    implementation of threading.Thread. This fixes a related issue in
    that, previously, calling server.wait() on a blocking executor from
    another thread would not wait for the completion of the executor. This
    has a knock-on effect in test_server's ServerSetupMixin. This mixin
    created an endpoint with a stop method which called server.stop().
    However, as this is executed by the executor, and also joins the
    executor thread, which is now blocking, this results in a deadlock. I
    am satisfied that, in general, this is not a sane thing to do.
    However, it is useful for these tests. We fix the tests by making the
    stop method non-blocking, and do the actual stop and wait calls from
    the main thread.

Fix assumptions in test_server_wait_method
    
    test_server_wait_method was calling server.wait without having
    previously called server.start and server.stop. This happened to work
    because it also injected server._executor_obj. This is problematic,
    though, as it assumes internal details of the server and does not
    represent the calling contract of server.wait, which is that it must
    follow server.stop (which must itself also follow server.start).
    
    This change makes the necessary changes to call server.wait in the
    correct sequence.

Rename MessageHandlingServer._executor for readability
    
    MessageHandlingServer has both MessageHandlingServer.executor, which
    is the name of an executor type, and MessageHandlingServer._executor,
    which is an instance of that type. Ideally we would rename
    MessageHandlingServer.executor, but as this is referenced from outside
    the class we change _executor instead to _executor_obj.
