fix: improve reliability of proxy mock server tests#810
Merged
Conversation
- Fix race condition in socket handoff by making it synchronous:
- Handler now blocks waiting for socket via message
- Socket is sent after controlling_process completes
- This ensures handler never tries to use socket before ownership
transfer is complete
- Increase timeouts for CI reliability:
- Accept timeout: 100ms -> 500ms
- Recv timeouts: 5s -> 10s
- Connect timeouts: 5s -> 10s
- Socket handoff wait: 1s -> 10s
These changes address flaky proxy integration tests that occasionally
failed on Linux x86_64 OTP-28 CI runners with errors like
{connect_proxy_failed, proxy_error} and {socks5_proxy_failed, badarg}.

Summary
Background
Proxy integration tests were occasionally failing on Linux x86_64 OTP-28 CI runners with errors like
{connect_proxy_failed, proxy_error}and{socks5_proxy_failed, badarg}.The root cause was a race condition in socket handoff: the spawned handler process could try to use the socket before
gen_tcp:controlling_processcompleted. The fix ensures the handler blocks until the socket is explicitly sent to it after ownership transfer.
