| | | | | | | | | | | | | | | | | | | | | | | | Use the rabbit_ha_queues boolean option. It is off by default, and you need to wipe RabbitMQ Mnesia database (/var/lib/rabbitmq/mnesia) when changing it. Change-Id: Id06692a142d1e5316602f6ceed4ccad615ce74c1

* | | fanout subscriptions in impl_zmqEric Windisch2012-09-202-20/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This necessary to support Quantum's scalable agents in the Folsom release. Supports matchmaking and subscribing to publishers, in addition to sender-only fanout broadcasting. Until now, senders of fanout messages had to know of all recipients via the matchmaker. This patch allows recipients to discover message publishers via the matchmaker. This is useful in patterns when there are few publishers, but many subscribers. The raw message passed to ZeroMQ is changed so that zmq_subscribe can filter by topic. This patch may be partially reverted in Grizzly, after the arrival of the ServiceGroupAPI which will significantly improve the matchmaking capabilities.

| * | | Normalize_time() always return naive objectYunhong, Jiang2012-09-131-2/+4
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the timeutils.normalize_time() returns naive datetime object when parameter timestamp is an naive object or a non-UTC aware datetime object, and returns aware datetime object if parameter timestamp is a UTC aware datetime object. The basic problem here is that utcoffset() of None means the object is naive but a utcoffset() of zero means that the object is aware but represents UTC time. This is fragile implementation and will trigger potential issue, because aware/native datetime is not interoperatable. For example, "timeutils.utcnow() > timeutils.normalize_time(m)" will success at most time, while trigger TypeError if m is a UTC aware object. We want to normalize all objects into naive objects.

| * | Change the qpid_heartbeat default to 60 seconds.Russell Bryant2012-09-131-1/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The heartbeat option enables sending a message at the AMQP layer at a regular interval. This helps ensure that the connection is still up and working. Once a failure is detected, a reconnection can be attempted. The default for qpid_heartbeat was previously 5 seconds. This is pretty aggressive and can lead to invalid timeouts occuring. An example is the nova-compute service. It may block in native code (such as libvirt) under normal circumstances. When this happens, other greenthreads (such as the one responsible for sending the heartbeat) can not be scheduled. This patch makes the default a less aggressive 1 minute. Fix bug 1050661.

* / Added a method for parsing host:port pairs.Eugene Kirpichov2012-09-111-0/+44
|/ | | | | | | | | | | | The method works correctly with ipv6. An alternative way would be to use urlparse, but urlparse only works correctly starting with Python 2.7, so to be compatible, we have to reimplement this part.

| * Update zmq context cleanup to use term.Dan Prince2012-08-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Updates the RPC cleanup function for the zmq RPC driver to use Context.term() instead of Context.destroy(). This allows the Nova code to work with older versions (pre 2.1.10) of pyzmq. The Context term() function seems to do the job just as well as destroy() (and is also thread safe) so lets just use it instead. Fixes LP Bug #1044004.

* | Allow non-string items in the creds dict.Vishvananda Ishaya2012-08-201-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | The generic checking in policy allows us to match against data from the creds_dict using a very simple syntax. For example, in policy.json if you had something like: "some_action": [["project_id:foo"]] it would only allow project foo to perform that action, but something like: "some_action": [["is_admin:True"]] where is_admin is a boolean fails. This modifies the check to convert the value to unicode before attempting to compare it. It includes a test. Fixes bug 1039132 Change-Id: I0e53a6ea2709212d4a1536f901bcf1e717a232ca

This patch adds support for overriding with a None value by adding a special internal class. set_override('foo', None) will now override the existing value with None. This is a slight change to the existing behavior, so this patch adds two calls for the old functionality of clearing defaults and overrides. Example syntax for the new calls are shown below: conf.clear_default('foo') conf.clear_override('foo') The patch also updates the tests to reflect the change in functionality and adds new tests to verify the new functionality.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Related to blueprint cfg-global-object When using the global config object pattern, you often have modules which define options that are referenced in other options. So, for example if module A defined option 'foo' and module be needed to reference that option, you might do: import A print CONF.foo However, this makes it entirely unclear to the casual reader why module A was imported. Nova has a flags.DECLARE() function that helps with this problem by allowing you to do: flags.DECLARE('foo', 'A') The function simply imports module A and checks that the 'foo' option is now defined in the global config object. This is fine, but it is also implicit that this function applies to the global config object. Instead, let's do the following: CONF.import_opt('foo', 'A') Change-Id: I7b98f5be71068bbde70cc0eab991eaebb577de52
