v0.8.0 example client/server error

[so-schen]

Version

v.0.8.0 platform: macos, M2

Steps to reproduce

1. start server RUST_LOG=info cargo run --example server -- ./ --listen 127.0.0.1:4433
2. start client RUST_LOG=info cargo run --example client https://localhost:4433/Cargo.toml

Failures

Can not setup connection, the ip and port 16.2.220.1:127 is unknown, seems it is trying to use a client address that from somewhere?

Why are you on 0.8?

[gftea]

@djc , we have old software using crate that depends on this version, and I am looking into if this version is stable and any known issues

[Ralith]

We don't have the resources to provide support for old versions. I'd strongly encourage updating; 0.8 is pretty old, but most APIs should still be similar.

[gftea]

I fully understand that, but by chance you may remember or know the possible cause, why the server tried to send to destination of a unknown socket addr?

[Ralith]

It could be the bug fixed in https://github.com/quinn-rs/quinn/pull/1391. If you're on 0.8.0 then perhaps you didn't pick up quinn-udp patch level fixes either. You should at the very least update to quinn 0.8.4 and quinn-udp 0.1.3, which will require no changes in your code. Pinning old patch versions is inviting avoidable breakage just like this.

Thanks @Ralith ! Ticket can be closed.
