Publish/Subscribe issue with mixed RCF versions

Hello, here is an issue with using RCF publish/subscribe with different RCF versions. Publishing an event from a publisher (v3.2) to a subscriber (v2.2) is somehow silently swallowed. Nothing happens on subscriber side, no event is received and no error is thrown on either subscriber or publisher si...

Enable TCP socket option KEEPALIVE

Hello Jarl and all others, here is a question about the possibility of enabling keep-alive packets for socket connections on client-side. The goal is that the client will be notified via the TCP keep-alive feature if a connection faces problems. With access to the underlying native handler and some ...

Re: Turn On/Off Nagel algorithm?

Hello, sorry for hijacking this thread. But i think that this is an extension to the original question relating to set TCP_NODELAY. We have a Publisher/Subscriber implementation here. And on Win7 we can see delays of 200 ms. The delays are observed on subscriber-side when the publisher tries to send...

Re: Creating callback connection established new connection.

Hi Jarl, well, this is embarrassing. :oops: The callback connection still established two connections, even with the addtional statement in Marshal.cpp . In my test scenario the second connection was made somewhat later on but is still created. Somewhere in TcpAsioServerTransport (e.g. method implTr...

Re: Creating callback connection established new connection.

Hi Jarl, thanks for your response and your remarks to the topic. But i disagree with your statement if you want to keep on making regular client-to-server calls, you need to setup a new RcfClient<>, which will have its own TCP connection to the server. With my experiences so far with RCF, this is no...

The Android platform was evaluated for the possibility of using the rcf library in version 1.3.1. At last the creation and using of a static lib was successfull with an additional small patch, attached in this post. I am not sure if the rcf framework is tested or even supported on this platform by y...

Re: Initialize a SubscriptionService before sending data.

Ok, late, but here is an answer post :) Thanks for your answer jarl. Here is it how it is implemented now in case someone is interested in. Now on the client side there is one RcfServer which serves the following purposes: It should listen for UDP Broadcasts if a service is somewhere available where...

Initialize a SubscriptionService before sending data.

Is it possible to remotely initialize a service subscriber while conneting before it get service data through the publishing service? In RCF there is the possibility to install a setOnConnectCallback function in the publisher. The callback knows the RCF Session object. Now this object is converted v...
