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/
This correction to the previous commit leaves the <sstream> header in, because
std::stringstream has been using already before and the header was missing.
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.
* move Plugins::Version to fair::mq::tools
* fix Parser interface
* make device a shared pointer in main
* provide std::hash template specialization
* fix FairMQ.Plugins/FairMQ.PluginsStatic when run with ctest
* fix MQ/serialization example
* add --no-as-needed flag
* GCC 4 does not support member refs, move to pointer types
* 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.
