Previously if multiple attempts to call consume were made, then
QAmqpQueue would send a frame for each of them leading to multiple
consumer tags and general confusion. This guards from calling
consume multiple times.
On socket errors we always close the socket per amqp specification,
however there is no need to do so if the connection has already been
forcibly closed from the server side. This causes recursive loops
when using SSL connections
Provides an accessor and change signal for the state of QAmqpClients
internal ssl socket. This also defaults the internal socket to low
latency mode, as well as keep alive.
This gives an example of how you can use QMetaObject::invokeMethod to
call a QAmqpExchange from another thread. Also, moved the qRegisterMetaType
for QAmqpMessage::PropertyHash to the ctor of QAmqpClientPrivate
tuneOk was only properly tuning the heartbeat delay value for values
larger than the default delay sent by the server. This changes that
behavior to send back the requested heartbeat delay if one was provided
This is a bit of a contrived example, since I explcitly have left
out a synchronous API for QAMQP, however, it still shows how one can
use the CorrelationID and ReplyTo properties to implement RPC behavior
QAmqpExchange and QAmqpQueue both have a number of actions associated
with them that should be defined as slots (especially for a potential
future where they are exported as QML objects). This is a step in the
direction of fully making these classes scriptable
nextChannelNumber is being incremented twice. When the counter wraps
around it starts declaring already existing channels and the AMQP server
disconnects the client. This patch doubles the number of channels that
can be created before this happens.
A public accessor and mutator was provided for using a QSslConfiguration
with a QAmqpClient, however the configuration was never actually assigned
to the internal socket. This patch fixes that, and removes the needless
storage of a copy of the QSslConfiguration as well
In cases where exchanges and queues are added and deleted during
an extended use of a QAmqpClient, the client should internally cleanup
the frame handlers registered for those objects. This patch does that
as well as providing two test cases verifying this behavior for both
QAmqpQueue and QAmqpExchange.
When a socket error occurs the string version of the error is now
stored in QAmqpClient's internal errorString variable, providing
access to the string to users of the client.
This adds preliminary support for SSL connections to a RabbitMQ
server. Instead of providing two clients (QAmqpClient/QAmqpSslClient),
the SSL support was directly rolled into QAmqpClient itself, providing
signals/slots to deal with errors (sslErrors/ignoreSslErrors), and
the ability to assign a QSslConfiguration. Travis testing for ssl
support is currently disabled, pending a solution to a travis
limitation for starting ssl listeners
Since you can provide amqps endpoints, it makes no sense to have a
separate class for SSL client support. This functionality will be
merged directly into QAmqpClient
QAmqpQueue and QAmqpExchange both now have an isDeclared property,
and QAmqpChannel::isOpened was renamed to isOpen to more closely follow
Qt style/api guidelines
RabbitMQ supports publish confirms (Publisher Acknowledgements) on
a given channel. This enables the user to toggle this functionality
and ensure that published messages are in fact published.
- opt for QDataStream overloads instead of read ctor and toStream methods
- removed some unneccesary prefixes to Type and MethodClass enums
- removed documentation from header (this is coming back!)
- cleaned up some confusing code paths, removed unneccessary methods (like readHeader/writeHeader)
This is a very small library, so there is no real pressing need for
a library namespace. Further, the namespacing actually makes it rather
difficult to work with in some cases. Opting for a more "Qt" style
class naming scheme, using the QAmqp class prefix
The internal buffer should not be used blindly when reading
Frame::HEADER_SIZE, as it is error prone and adds nothing over reading
on the stack (and it's only 7 bytes). There are places in this class
where buffer.clear() is called.
amqp_<filename> is used in at least two other C/C++ projects related
to amqp, so this commit changes all our source to use a qamqp header.
This avoids potential clashes, and is more in line with Qt style
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
