tunnel_manager.py DOX

Purpose

• Own the tunnel_manager.py helper module.
• This module selects and coordinates configured tunnel providers.
• Keep this file-level DOX profile synchronized with tunnel_manager.py because this directory is intentionally flat.

Ownership

• tunnel_manager.py owns the runtime implementation.
• tunnel_manager.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• TunnelManager (no explicit base class)
  • get_instance(cls)
  • get_notifications(self)
  • get_last_error(self)
  • start_tunnel(self, port=..., provider=...)
  • stop_tunnel(self)
  • get_tunnel_url(self)
• Top-level functions:
• normalize_provider(provider)
• Notable constants/configuration names: SUPPORTED_TUNNEL_PROVIDERS, TUNNEL_PROVIDER_ALIASES.

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: tunnel state.
• Imported dependency areas include: collections, flaredantic, helpers.cloudflare_tunnel, helpers.microsoft_tunnel, helpers.print_style, helpers.serveo_tunnel, helpers.tailscale_tunnel, helpers.tunnel_common, threading, time.

Key Concepts

• Important called helpers/classes observed in the source: strip.lower, threading.Lock, join, ValueError, deque, self.notifications.clear, ServeoTunnelHelper, self._ensure_subscribed, strip, notifier.subscribe, CloudflareTunnel, MicrosoftDevTunnel, TailscaleTunnel, normalize_provider, threading.Thread, tunnel_thread.start, cls, event_value, PrintStyle.error, self._append_notification.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_tunnel_remote_link.py
