Client cancellations aren't propagated to the server

When I close a streaming client request with an exception I would expect the corresponding server receive channel to throw an exception upon calling receive (or iterating the channel) but it doesn’t seem to do so - am I doing something wrong?

Client:

call.requestChannel.close(Exception("Testing Exception"))

Server:

try {
    for (request in requestChannel) {
        logger.info("Iterating")
    }
    logger.info("Closed normally")
} catch (e: Exception){
    logger.error("Caught exception", e)
}

I can confirm this is a bug. I think it was introduced when outbound flow control was reworked. It is actually addressed in the streaming machinery rewrite that is currently in progress. Since that rewrite is still in alpha stages, I’ll get a fix out for this bug in the very next release. The release is expected to occur on this up coming Monday. Ill get a PR opened tonight and tag you for visibility.

Hi Marco - thanks for the response (and the library).

I’ve replicated the issue I’m seeing in this repo: https://github.com/jebbench/kotlin-coroutines-gRPC-template

If you need anything else let me know.
