QAMQP::Frame used to be public API mostly for MessageProperties. There
is no longer a need to keep this API public, as it should all be wrapped
with the cleaner Message/Queue/Exchange/Client API set
Though it's not necessarily recommended (per spec), Channels can be
shared by multiple Exchanges and Queues. I've added a test here showing
that's possible with QAMQP
We had frame handlers for Close messages from the server, but were not
doing our due diligence and sending a corresponding CloseOk back to the
server after processing. It seems RabbitMQ is generous in this case, but
at least we're doing it the right way now
Fleshed out the previously unimplemented flow control frame handling,
added an auto test for it. Also refactored out the stateChanged ChannelPrivate
method, if we need proper state support in the future it will be added with
a better implementation
existing tests have been immediately declaring queues and exchanges, and
not testing non-delayed declaration (queue/exchange is OPEN when declaration
occurs). these new tests cover this case
There are two distinctive type sets in AMQP, the basic AMQP types
and then the superset of Table value types. This commit attempts to
make that distinction more clear by the addition of a Table class.
Basically, AMQP value type read/write support is left in Frame for the
time being, while table value field read/write support has been moved
to the Table class. Also, a number of type differences exist between
the spec and rabbitmq's binary parser (noted in the errata page) which
were not previously honored.
the message was being needlessly duplicated into the Content frame,
now we only store the size there to be sent out, rather than the whole
message
remove QAMQP prefix in authenticator
the qos autotest required initially for us to wait for messages to
be added to the queue before running the test, and this was flakey
at best. these changes make it much more dependable
MessageProperties is currently defined in Frame::Content, which makes it
cumbersome to use when working directly with a Message itself. I attempted
to make this easier by using typedefs, but it's become pretty obvious that
it belongs in the Message class itself.
AMQP Basic qos support added to Channel class. There is an option
for global qos which is currently not added. Also, added auto tests
for qos definition, proper qos operation and verifying that RabbitMQ
does not support prefetchSize.
removed noAck as it relates only to the synchronous get AMQP api
moved noAck to get method
applied visual separation in headers between AMQP Queue and AMQP Basic methods
a Queue can act as a consumer in QAMQP, but previously we did no checks
to ensure that a Queue sent a request to consume only once. This commit
adds API for checking and ensuring that this is the case. Also, I reverted
the changes to allow multiple consumer tags because this was incorrect.
Also included is a new signal "consuming" to notify when consumption occurs,
and auto tests have been updated to use this, as well as verify that it
can only occur once per-consumer
- add publish options to Exchange (these need to move to a Basic abstraction)
- listen for bmReturn in Exchange to catch errors
- added auto tests to check behavior of an invalid mandatory publish
- cleaned up bit fields in exchange and queue
Messages used to be "delivered" and pushed right onto the queue, which
is where the requirement for Message to be explicitly shared came from.
Now messages that are incomplete come in and are stored in a "currentMessage"
private member (there is a requirement that messages are delivered in this
fashion, by the spec). Once the message body has come in, it is put into
the local queue and the messageReceived signal is emitted.
Also, modified Queue to be able to track a number of consumer tags. This
was exposed by the "routing" tutorial, where a single consumer can bind
to a number of exchanges with a generated consumer tag. The previous example
did not run into this problem because it used an explicitly set consumer tag
and therefore there were no conflicts.
