RTC SDK v6.0 RC2 does not aware of connection lost/error.

[sswang]

Hi,

Here is what we found when testing project:

In RTC 5.x versions, when I deliberately pulled out network cable:

1. All network traffic stoped, but none app in Windows awares of it, include RTC SDK.
2. Force RTC SDK to send something out, now this situation is detected and RTC SDK will fire an connection error(or else) event to reflect it, just like what other apps will do.
3. We are able to do something about it.

But in 6.0 RC2, the behavior will be:

1.....
2. Force RTC SDK to send something out, it still CANNOT detect this situation and fire NO connection error event (or is there a new event for it that I didn't know?).
3. There's nothinng we can do....

It also happens when connection lost for some reason(not "pull out cable" trick), no connection lost event is fired.

This should not happen, because there were no changes in the event mechanism, nor in the lower-level socket implementations between v5.17 and v6.0 RC2.

1. What is the exact RTC SDK version you were using before moving on to RTC SDK v6.0 RC2? I need this version number, so I can compare changes made on the low-level code to see if something could have resulted in this new behavior.

2. Which Delphi version are you using and for which target platform are you compiling your Project?

3. Please send me a short example Project which demonstrates the problem, with a short explanation on how to reproduce the issue:

The last version I use is 5.11. After I tried to make a demo project and run it, the problem is gone and I cannot reproduce it anymore. An connection lost event will be triggered correctly right now. The weired thing we saw just happened once. We will keep testing, Thanks for your quick response.

Thanks for your feedback. Please keep me posted on this. Should the problem reapear and you can reproduce it with a short example, please forward it to me and I will take a closer look.
