Server side streaming continues despite loss of client

[Robert Bielik]

Hi,

I have a C++ client/server and an RPC where a progress message is sent back to the client. However, if the client dies unexpectedly, the server side keeps on

sending message without fail, i.e. writer->Write(msg) does not return false.

I'm using gRPC v1.0.1.

I build the server with grpc::ServerBuilder, and there is no explicit option set for it. Anything here I can do ?

Regards

What you're saying smells to me like issue 11157 (never mind the Python/C++ distinction; the problem is suspected to be in shared code) although we're not aware of it having been introduced as early as 1.0.1.  Are you able to upgrade to a more recent version of gRPC and confirm your observations?

I tried tag v1.4.0 right now, but CMake fails on a lib called "cares" ?

"You have called ADD_LIBRARY for library cares without any source files. This typically indicates a problem with your CMakeLists.txt file."

Is the CMake stuff up to par on v1.4.0 ?

Maybe; I'm not too familiar with that part of building gRPC but someone else certainly is (another reason to retain the list in the conversation).

It seems I was a bit too hasty. Always miss that submodule update thing... hrmf...

Glad to hear you're moving forward.

It seems I was mistaken, the continued streaming was due to a future that didn't get cancelled properly, so the application was still running in the background. If I kill the app via taskmanager, the streaming stops from the server, just as expected. I've tried both v1.0.1 and v1.4.0.
