Callbacks are called when the data buffer of the message assiciated
with the corresponding region is no longer needed by the transport.
Example in examples/advanced/Region/
Devices implementing the conditional run method are typically source
devices and a rate control can be desireable. New option '--rate' with
a float number argument in Hz can be used to configure rate control.
By default it is switched off.
* 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.
- Add shared memory example in examples/MQ/SharedMemory
- Device/Task termination: try soft first, and abort if it fails
- Interactive mode: prevent cin from blocking forever (poll)
- 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.
- Remove the compile time check of the transport implementation.
The transport (zeromq/nanomsg) can be chosen at run time with:
`device.SetTransport("zeromq"); // possible values are "zeromq" and "nanomsg"`.
For devices that use FairMQProgOptions, the transport can be configured via cmd option:
`--transport zeromq` or `--transport nanomsg`. Default values is "zeromq".
The device receives the configured value with:
`device.SetTransport(config.GetValue<std::string>("transport"));`
Old method of setting transport still works. But the NANOMSG constant is not defined.
- Remove old `fairmq/prototest` directory. It was only used as a test for protobuf.
The protobuf part of Tutorial3 does the same (with different values).
- Fix a bug in FairMQPollerNN, where the `revents` value was not initialized.
This caused the `poller->CheckOutput()` to trigger when it should not.
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.
