(await RequestStream.ReadAllAsync()) of stream in server is not waken when turn off client wifi. #1669

Open kimk-s opened 2 years ago

kimk-s commented 2 years ago

What version of gRPC and what language are you using?

2.44.0

What operating system (Linux, Windows,...) and version?

Windows

What runtime / compiler are you using (e.g. .NET Core SDK version dotnet --info)

6.0.201

What did you do?

  1. Run the server
  2. Run the client (running on a different computer than the server)
  3. Bidirection stream is connected, and turn off client wifi.

Proto file: https://github.com/kimk-s/RpcTest/blob/main/Proto/greet.proto Server service code: https://github.com/kimk-s/RpcTest/blob/main/Server/Services/GreeterService.cs Client code: https://github.com/kimk-s/RpcTest/blob/main/NetClient/Program.cs

What did you expect to see?

Then, RpcException is thrown in client, And I expected (await RequestStream.ReadAllAsync()) is waken in server(https://github.com/kimk-s/RpcTest/blob/main/Server/Services/GreeterService.cs#L25).

What did you see instead?

is not waken until server is stopped after 8 hours.

Something you could try is enabling server keep-alive pings in Kestrel.

See https://docs.microsoft.com/en-us/aspnet/core/fundamentals/servers/kestrel/options?view=aspnetcore-6.0#http2-keep-alive-ping-configuration
