! THIS PATCH BREAKS NANOMSG TRANSPORT !
The subscriber command socket was created using the transport factory of
the channel which might not implement sub sockets. This patch creates
the subscriber command sockets in the device initialization and passes
them down (move) to the command interface initialization.
This patch puts more focus on the GetSocket interface of FairMQSocket,
because all command sockets are now implemented with the default
transport - the channels use an internal poller which polls over sockets
of potentially different transports now (e.g. zeromq command socket and
nanomsg data socket). Basically, all transports need to return file
descriptors compatible to be used in a single poll set. THIS IS NOT THE CASE!
! THIS PATCH BREAKS NANOMSG TRANSPORT !
* FairMQTransportFactoryZMQ: move the config invariant
initialization to ctor
* FairMQChannel: add new ctor that creates usable channel
* FairMQSocket*: close sockets in dtor
* FairMQTransportFactory*: terminate context in dtor
* FairMQChannel: add Bind/Connect facades (for explicit control, e.g. timing)
- give transport Initialize() method with access to device config.
- avoid using global context in the transport.
- simplify shutdown procedure (no need for extra thread).
- Avoid polling when only one input channel is used.
- Send only handles for shared memory transport.
- Avoid waiting in the rate logger thread when nothing to log.
- Hide warnings from generated files
- Fix#483
- Convert factory methods to return smart ptrs.
- Refactor state machine to use same thread for user states.
- Remove unused includes and dependencies, use std.
Sent messages will be scheduled among the endpoints according to socket
type: PUB will send the same data to all endpoints simultaneously, PUSH
will do round robin transfer.
Incoming data is fair queued between endpoints.
This is a feature of at least zeromq and nanomsg.
_____________
To use: in the device configuration, instead of specifying just one address,
specify a comma separated list e.g.
tcp://localhost:123,ipc:///tmp/socket
the connection method (bind/connect) applies to all endpoints in this case.
______________
Mixing binding and connecting endpoints is supported:
prefix "@" means "bind", "+" (or ">") means connect, e.g.
+tcp://localhost:123,@ipc:///tmp/socket,ipc:///tmp/asd
(in case of missing prefix, the default channel method is used for that
endpoint).
- OnData() channel data handler.
- ConditionalRun() for devices without incoming data.
- Header file with common main(), to be extended with getDevice/addCustomOptions.
- Update examples (MQ/Tutorial3) to use the new API and config.
- NewSimpleMessage() for simpler creation of small messages (additional copy).
- Replace SetProperty/GetProperty with fConfig access.
- Runtime configurable channel names for common devices.
- Configurable logging interval per channel.
- FairMQMultiplier for distributing same data to multiple outputs.
- Cleanup state machine messages.
- Cmd option to toggle signal handling.
- Simpler API for send/receive timeouts.
- Enable --log-to-file.
- Fix coverity issues, warnings.
- Various code cleanup and minor tweaks.
- Update DDS example command UI and extract it from example.
- Unify address handling via DDS properties for dynamic deployment.
- Update DDS docs with the new approach.
- Allow `--config-key` to be used to access common config in JSON.
- Allow common channel properties to be specified for all sockets.
- Update MQ examples and Tuto3 with new config options.
- Add start scripts to MQ examples for easier use.
- Implement nanomsg multipart with MessagePack.
- Use the MessagePack from FairSoft and handle not found case.
- Update splitter, merger and proxy devices to handle multi-part.
- Let FairMQParts.At() return pointer reference (can be used for moving).
- Add missing const specifier in the message interface.
- Add transmit kernel size setting to channels (ZMQ_SNDBUF).
- Remove FairMQBuffer device.
- Remove old multi-part methods from Tutorial3 example (to be replaced with Parts API).
- Make callback mandatory for newMsg(data, size, callback).
- Add missing <vector> include in FairMQSocket.
- Extend the multipart API to allow sending vectors of messages or helper
thin wrapper FairMQParts. See example in examples/MQ/8-multipart.
- NewMessage() can be used in devices instead of
fTransportFactory->CreateMessage().
Possible arguments remain unchanged (no args, size or data+size).
- Send()/Receive() methods can be used in devices instead of
fChannels.at("chan").at(i).Send()/Receive():
Send(msg, "chan", i = 0), Receive(msg, "chan", i = 0).
- Use the new methods in MQ examples and tests.
- No breaking changes, but FAIRMQ_INTERFACE_VERSION is incremented to 3
to allow to check for new methods.
Fix Weffc++ warnings
- Add missing copy constructors and assignment operators .
- Hide the warning from FairMQStateMachine.h where it is produced by boost and/or is intended.
- Some code cleanup.
- Move general config files out of example directory to fairmq/run.
- Use FairMQProgOptions for MQ example 5.
- Add SendPartAsync() for non-blocking send of a message part.
- Rename Tutorial3 MQ files for uniform naming.
- Add search for dylib in FindDDS.cmake (OSX).
- Add more detail to the DDS example readme.
- MQ Example 3 (DDS): choose network interface via command line option.
- Give FairMQ examples their own CMakeLists.txt for clarity.
- Remove C++11 checks in Tutorial3 from the code (they are now in CMake).
- Add Serializer for device properties (FairMQDevice::ListProperties()).
- FairMQ: add possibility to poll on multiple channels.
- FairMQ: include command channel when polling on blocking calls (for unblocking without termination).
- FairMQ: move signal handler inside of FairMQDevice class (call FairMQDevice::CatchSignals() in the main function).
- FairMQ: add 'bool CheckCurrentState(statename)' (instead of 'GetCurrentState() == statename' that cannot be thread safe).
- FairMQDevice: add 'InteractiveStateLoop()' method that can be used to change states from the command line.
- FairMQDevice: add automatic transition to IDLE state if Run() exits without an external event.
- FairMQDevice: implement device reset.
- FairMQDevice: use unordered_map for device channels.
- FairMQChannel: improve address validation for channels.
- FairMQChannel: add ExpectsAnotherPart() method to check if another msg part is expected (old approach still works).
- FairMQ: remove invalid transition from the run files.
- FairMQFileSink: disable ROOT termination signal handler.
- Tutorial3: spawn xterm windows from start scripts without overlapping for better visibility.
- FairMQ Examples: update protobuf test and move its files to a common directory.
- FairMQStateMachine: improve feedback on invalid transitions (more readable).
Organize sockets as a map of vectors of FairMQChannels.
Update FairMQStateMachine by removing SETTINGINPUT, SETTINGOUTPUT,
BIND and CONNECT states and by adding INITIALIZING_TASK, RESETTING_TASK
and RESETTING_DEVICE states. Run states functions in their own thread.
