target-cpu=native breaks client ability to connect to server inside container and remote server #41

Open Fogapod opened 9 months ago

Fogapod commented 9 months ago

Any network indirection (connecting to remote server or local/remote container) prevents client from spawning.

docker server command: run --name ssnt --network host --rm -e RUST_LOG=debug ssnt --public-address 127.0.0.1 (broken with both --network host and manual port)

After attempting to spawn as any role both client and server log connection once:

# client
2024-01-11T13:37:51.856986Z  INFO networking: Joining server 127.0.0.1:33998
2024-01-11T13:37:51.913513Z  INFO networking: Connected to server
2024-01-11T13:37:51.985569Z  INFO networking: Joined server tick=0.016666668

# server
024-01-11T13:37:51.937588Z  INFO networking: New client connected connection=ConnectionId(1704980271857) id="cceb82c6-047e-f4d0-cceb-82c6047ef4d0"

Next server log should be INFO ssnt::body: Created creature but it never gets there. Client is stuck in main menu. Hosting server outside container works and i cannot reproduce bug.

I tested a bunch of things so far, none of these change behaviour (local works, container doesnt):

I ran client in pdb and it seem to be stuck in some deadlock:

I eventually discovered that "-C", "target-cpu=native" rustc flag causes this to happen. I am not sure how to debug this further

Fogapod commented 9 months ago 
[target.x86_64-unknown-linux-gnu]
linker = "/usr/bin/clang"
rustflags = ["-C", "link-arg=--ld-path=/usr/bin/mold", "-C", "target-cpu=native"]

removing "-C", "target-cpu=native" fixed this. i have no idea how it bugged out in a way game couldnt connect to container. there is a bug in linux or linkers or clang
