Hi,

In MamaTransport.cpp:83 the status codes MAMA_TRANSPORT_CONNECT_FAILED/MAMA_TRANSPORT_WRITE_QUEUE_LOW_WATER_MARK/MAMA_TRANSPORT_WRITE_QUEUE_HIGH_WATER_MARK are missing from the list. Java is the same as C++.

Is this for a specific reason or just missing?

If missing I can submit a patch with new callbacks.

Thanks,

Reed.

Hi Reed,

Thanks for your email.

In regards to the status codes

- MAMA_TRANSPORT_CONNECT_FAILED

- MAMA_TRANSPORT_WRITE_QUEUE_LOW_WATER_MARK

- MAMA_TRANSPORT_WRITE_QUEUE_HIGH_WATER_MARK

The Water Marks have not been ported across because they are not necessary.

C++ and Java  have their own implementation callbacks “onHighWatermarkExceeded” etc,  whereas within C we need to specifically set the callbacks, but if you require these please feel free to submit a patch for consideration.

Transport failed was historically used in an old middleware, but is now no longer required so therefore has not been ported to C++ or Java, but again please feel free to submit a patch.

Thanks,

Adrienne

Hi Reed,

On second thoughts, the callbacks are the internal MamaQueue.  

Possibly it may have been added for Avis [which is deprecated] let us look into it a bit more.

Thanks,

Hi,

The context is that for the Tick42 bridge when the user is not valid (not in DACS) then the bridge sends MAMA_TRANSPORT_CONNECT_FAILED to the transport callback, but the C++ app does not get a callback.

Thanks,

Reed.

If the status codes are defined in the fundamental C API then the language bindings that build on that layer must support them. This is supposed to be middleware agnostic – you can’t make assumptions about whether connection failures are going to be synchronous  or not. Some platforms they might be, others they are not.
