* fix(gateway): race condition, photo media loss, and flood control in Telegram
Three bugs causing intermittent silent drops, partial responses, and
flood control delays on the Telegram platform:
1. Race condition in handle_message() — _active_sessions was set inside
the background task, not before create_task(). Two rapid messages
could both pass the guard and spawn duplicate processing tasks.
Fix: set _active_sessions synchronously before spawning the task
(grammY sequentialize / aiogram EventIsolation pattern).
2. Photo media loss on dequeue — when a photo (no caption) was queued
during active processing and later dequeued, only .text was
extracted. Empty text → message silently dropped.
Fix: _build_media_placeholder() creates text context for media-only
events so they survive the dequeue path.
3. Progress message edits triggered Telegram flood control — rapid tool
calls edited the progress message every 0.3s, hitting Telegram's
rate limit (23s+ waits). This blocked progress updates and could
cause stream consumer timeouts.
Fix: throttle edits to 1.5s minimum interval, detect flood control
errors and gracefully degrade to new messages. edit_message() now
returns failure for flood waits >5s instead of blocking.
* fix(gateway): downgrade empty/None response log from WARNING to DEBUG
This warning fires on every successful streamed response (streaming
delivers the text, handler returns None via already_sent=True) and
on every queued message during active processing. Both are expected
behavior, not error conditions. Downgrade to DEBUG to reduce log noise.
* fix(gateway): prevent stuck sessions with agent timeout and staleness eviction
Three changes to prevent sessions from getting permanently locked:
1. Agent execution timeout (HERMES_AGENT_TIMEOUT, default 10min):
Wraps run_in_executor with asyncio.wait_for so a hung API call or
runaway tool can't lock a session indefinitely. On timeout, the
agent is interrupted and the user gets an actionable error message.
2. Staleness eviction for _running_agents:
Tracks start timestamps for each session entry. When a new message
arrives and the entry is older than timeout + 1min grace, it's
evicted as a leaked lock. Safety net for any cleanup path that
fails to remove the entry.
3. Cron job timeout (HERMES_CRON_TIMEOUT, default 10min):
Wraps run_conversation in a ThreadPoolExecutor with timeout so a
hung cron job doesn't block the ticker thread (and all subsequent
cron jobs) indefinitely.
Follows grammY runner's per-update timeout pattern and aiogram's
asyncio.wait_for approach for handler deadlines.
* fix(gateway): STT config resolution, stream consumer flood control fallback
Three targeted fixes from user-reported issues:
1. STT config resolution (transcription_tools.py):
_has_openai_audio_backend() and _resolve_openai_audio_client_config()
now check stt.openai.api_key/base_url in config.yaml FIRST, before
falling back to env vars. Fixes voice transcription breaking when
using a custom OpenAI-compatible endpoint via config.yaml.
2. Stream consumer flood control fallback (stream_consumer.py):
When an edit fails mid-stream (e.g., Telegram flood control returns
failure for waits >5s), reset _already_sent to False so the normal
final send path delivers the complete response. Previously, a
truncated partial was left as the final message.
3. Telegram edit_message comment alignment (telegram.py):
Clarify that long flood waits return failure so streaming can fall
back to a normal final send.
* refactor: simplify and harden PR fixes after review
- Fix cron ThreadPoolExecutor blocking on timeout: use shutdown(wait=False,
cancel_futures=True) instead of context manager that waits indefinitely
- Extract _dequeue_pending_text() to deduplicate media-placeholder logic
in interrupt and normal-completion dequeue paths
- Remove hasattr guards for _running_agents_ts: add class-level default
so partial test construction works without scattered defensive checks
- Move `import concurrent.futures` to top of cron/scheduler.py
- Progress throttle: sleep remaining interval instead of busy-looping
0.1s (~15 wakeups per 1.5s window → 1 wakeup)
- Deduplicate _load_stt_config() in transcription_tools.py:
_has_openai_audio_backend() now delegates to _resolve_openai_audio_client_config()
* fix: move class-level attribute after docstring, clarify throttle comment
Follow-up nits for salvaged PR #4577:
- Move _running_agents_ts class attribute below the docstring so
GatewayRunner.__doc__ is preserved.
- Add clarifying comment explaining the throttle continue behavior
(batches queued messages during the throttle interval).
* fix(update): handle conflicted git index during hermes update
When the git index has unmerged entries (e.g. from an interrupted
merge or rebase), git stash fails with 'needs merge / could not
write index'. Detect this with git ls-files --unmerged and clear
the conflict state with git reset before attempting the stash.
Working-tree changes are preserved.
Reported by @LLMJunky — package-lock.json conflict from a prior
merge left the index dirty, blocking hermes update entirely.
