Description
Bug
This isn't a significant bug but I found that when port 18081 is in use before starting cuprated the program aborts.
Expected behavior
Exit gracefully with an error message
Steps to reproduce
Example:
- run monerod
- start cuprated
Source Code Location
cuprate/binaries/cuprated/src/rpc/server.rs
Lines 84 to 87 in 97e5395
| tokio::task::spawn(async move { | |
| run_rpc_server(rpc_handler, restricted, addr, request_byte_limit) | |
| .await | |
| .unwrap(); |
