stops working when using in a loop #13

Closed timglabisch closed 7 years ago

timglabisch commented 7 years ago

i tryed rust-rpc, here is the code:

https://github.com/timglabisch/grpc_examples/blob/a56e668958e19b6b84ba069620012eb1af553673/rust_server/src/main.rs

when i run the php client php example.php gprc-rust and the php client are working well together. after a few thousand messages (depends on the package (string) length), grpc-rust stops working. it's totally reproducable. the node grpc implementation works, so it must be an issue with grpc-rust

Yes, I think the bug is in gRPC. HTTP/2 implementation in grpc-rust is very incomplete, and I think the reason behind hanging is missing window implementation (currently gRPC simply ignores WINDOW frames and does not sent it, which is wrong).

I'm going to fix it soon.

This particilar issues must be fixed in 39a07b687f6f88d1001139a8603a79b910d71afd.

Although window support is far from complete.
