grpclib-bug

A repository demonstating an issue with grpclib interacting with tonic using IPv6.

Steps to reproduce

1. Clone this repository
2. cd grpclib-bug
3. Install rustup (sudo apt install rustup)
4. cd helloworld-tonic
5. cargo run --bin helloworld-server &
6. cd ../client
7. python -m venv venv
8. . venv/bin/activate
9. python -m pip install "betterproto[compiler]==2.0.0b6" grpcio-tools grpcio protobuf
10. python grpclib_client.py

• Running python grpcio_client.py works.
• Running using IPv4 (listenting and connecting to 127.0.0.1) works.

Rebuilding the generated code

• python -m grpc_tools.protoc -I .. --python_out=. --grpc_python_out=. ../helloworld.proto `
• python -m pip install "betterproto[compiler]==2.0.0b6" grpcio-tools grpcio protobuf
