Note
Medium Risk
Touches tunnel startup/monitoring and HTTP error mapping, so regressions could impact tunnel reliability or change the surfaced error types/messages for consumers.
Overview
Improves tunnel diagnostics across the SDK and CLI by adding structured errors and surfacing richer failure details from the underlying
frpcprocess.The SDK now introduces
TunnelLimitReachedError, enrichesTunnelConnectionErrorwith an optionaltunnel_id, parsesfrpclogs to produce clearer connection failures, and preserves recentfrpcoutput for post-exit inspection. The API client also maps certain400responses to quota errors, handles additional timeout types, and includes astatusfield onTunnelInforeturned byget_tunnel/list_tunnels.The CLI now monitors tunnel process health after startup, prints tailored messages for connection/timeout/quota failures, and displays tunnel status in
listandstatuscommands.Written by Cursor Bugbot for commit deb0c8b. This will update automatically on new commits. Configure here.
