From 3d698ba4e115ebb1db2b7b8a71ba565ac54d4a90 Mon Sep 17 00:00:00 2001 From: Teknium Date: Sat, 4 Apr 2026 23:27:03 -0700 Subject: [PATCH] feat(gateway): live-stream /update output + forward interactive prompts Adds real-time output streaming and interactive prompt forwarding for the gateway /update command, so users on Telegram/Discord/etc see the full update progress and can respond to prompts (stash restore, config migration) without needing terminal access. Changes: hermes_cli/main.py: - Add --gateway flag to 'hermes update' argparse - Add _gateway_prompt() file-based IPC function that writes .update_prompt.json and polls for .update_response - Modify _restore_stashed_changes() to accept optional input_fn parameter for gateway mode prompt forwarding - cmd_update() uses _gateway_prompt when --gateway is set, enabling interactive stash restore and config migration prompts gateway/run.py: - _handle_update_command: spawn with --gateway flag and PYTHONUNBUFFERED=1 for real-time output flushing - Store session_key in .update_pending.json for cross-restart session matching - Add _update_prompt_pending dict to track sessions awaiting update prompt responses - Replace _watch_for_update_completion with _watch_update_progress: streams output chunks every ~4s, detects .update_prompt.json and forwards prompts to the user, handles completion/failure/timeout - Add update prompt interception in _handle_message: when a prompt is pending, the user's next message is written to .update_response instead of being processed normally - Preserve _send_update_notification as legacy fallback for post-restart cases where adapter isn't available yet File-based IPC protocol: - .update_prompt.json: written by update process with prompt text, default value, and unique ID - .update_response: written by gateway with user's answer - .update_output.txt: existing, now streamed in real-time - .update_exit_code: existing completion marker Tests: 16 new tests covering _gateway_prompt IPC, output streaming, prompt detection/forwarding, message interception, and cleanup. --- gateway/run.py | 211 ++++++++++- hermes_cli/main.py | 83 ++++- tests/gateway/test_update_command.py | 2 +- tests/gateway/test_update_streaming.py | 496 +++++++++++++++++++++++++ 4 files changed, 775 insertions(+), 17 deletions(-) create mode 100644 tests/gateway/test_update_streaming.py diff --git a/gateway/run.py b/gateway/run.py index 33bfa1d79fc..3feb0f0080c 100644 --- a/gateway/run.py +++ b/gateway/run.py @@ -517,6 +517,10 @@ class GatewayRunner: # Key: Platform enum, Value: {"config": platform_config, "attempts": int, "next_retry": float} self._failed_platforms: Dict[Platform, Dict[str, Any]] = {} + # Track pending /update prompt responses per session. + # Key: session_key, Value: True when a prompt is waiting for user input. + self._update_prompt_pending: Dict[str, bool] = {} + # Persistent Honcho managers keyed by gateway session key. # This preserves write_frequency="session" semantics across short-lived # per-message AIAgent instances. @@ -1737,6 +1741,26 @@ class GatewayRunner: self.pairing_store._record_rate_limit(platform_name, source.user_id) return None + # Intercept messages that are responses to a pending /update prompt. + # The update process (detached) wrote .update_prompt.json; the watcher + # forwarded it to the user; now the user's reply goes back via + # .update_response so the update process can continue. + _quick_key = self._session_key_for_source(source) + _update_prompts = getattr(self, "_update_prompt_pending", {}) + if _update_prompts.get(_quick_key): + response_path = _hermes_home / ".update_response" + response_text = (event.text or "").strip() + if response_text: + try: + tmp = response_path.with_suffix(".tmp") + tmp.write_text(response_text) + tmp.replace(response_path) + except OSError as e: + logger.warning("Failed to write update response: %s", e) + return f"✗ Failed to send response to update process: {e}" + _update_prompts.pop(_quick_key, None) + return f"✓ Sent `{response_text}` to the update process." + # PRIORITY handling when an agent is already running for this session. # Default behavior is to interrupt immediately so user text/stop messages # are handled with minimal latency. @@ -1744,7 +1768,6 @@ class GatewayRunner: # Special case: Telegram/photo bursts often arrive as multiple near- # simultaneous updates.
