Pair conditional approval buttons into rows of two so the full Allow Once /
Session / Always / Deny set stays readable instead of one truncated 4x1 row.
Follow-up hardening for the salvaged #69240 readiness gate (#67498):
- _start_polling_once now returns its (generation, progress_event) pair
so the strict cold-start gate binds to exactly the generation it
started, instead of re-reading self._polling_progress_event which a
concurrent recovery task may have replaced with a newer generation's
event (the G1/G2 race flagged in the #69240 review).
- Strict cold start no longer schedules background polling recovery: a
polling error during the readiness wait is captured by a strict
callback and fails the connect attempt immediately with a loud
OSError, so GatewayRunner disposes the partial adapter and retries
with a fresh one — no more waiting out the full readiness deadline on
a generation that already errored, and no G2-on-partial-app healing.
- After readiness is proven the strict callback delegates every later
polling error to the real background-recovery callback, preserving
the existing degraded/reconnect semantics for the polling lifetime.
- The readiness-timeout error message now states the deadline and that
the gateway will retry with a fresh adapter (loud failure, not a
silent wait).
- Regression tests: current-generation progress connects; a polling
error during strict cold start fails fast without scheduling
background recovery (the #67498 idle-threads shape); stale-generation
progress is rejected.
Progresses #67498
Use wall deadlines for deleteWebhook and start_polling, then fail cold startup unless getUpdates proves progress. This lets the gateway discard partial PTB state and retry with a fresh adapter.\n\nRefs #67498

Together with the salvaged #55339/#60741 commits this closes out issue
#53428's bug class; the salvaged #60751 linter rule in
check-windows-footguns.py now enforces it repo-wide (verified: 807 files
scanned, zero findings).
The Telegram adapter's connect retry loop could silently stall after
'Connecting to Telegram (attempt 1/8)...' with the event loop permanently
parked in select() — all threads idle, no attempt 2/8 ever scheduled.
Root cause analysis:
- The retry loop reused the same Application object across all
8 attempts. After a failed initialize() the app could be in a partially-
initialized state (closed httpx transports from ,
or flag set before the hang) causing subsequent calls
to silently skip real initialization.
- CancelledError (a BaseException, not an Exception) propagated silently
through all except handlers with no logging — the task driving the retry
loop could exit without any trace.
- No total watchdog bound existed for the entire retry loop; only per-attempt
timeouts via _await_with_thread_deadline. If the loop itself stalled
between attempts (between-attempt sleep, cleanup, or scheduling), there
was no timeout to catch it.
Fixes:
1. **Total watchdog deadline**: Compute a total deadline for the entire
connect loop (8 attempts × init_timeout + 120s margin). Before each
attempt, check the wall clock; if exceeded, raise OSError immediately
instead of attempting another initialize().
2. **Fresh Application per retry**: On each failed attempt, rebuild
via and re-register all handlers. The old
app is best-effort shutdown with . This ensures
each retry starts with a clean slate — no stale transports, no stale
flag, no leaked state from the previous attempt.
3. **BaseException logging + propagation**: Added
(placed LAST after all other handlers) to log CancelledError and other
non-Exception signals before propagating. Previously these exited the
retry loop silently with no log message.
4. ** block for app rebuild**: The clause runs after
every failed attempt that isn't the last, rebuilding the app and
discarding the old one regardless of which exception class caused the
failure.
Several platform fetch paths called is_safe_url before constructing ordinary httpx clients, leaving a second DNS lookup at connection time. This preserved the rebinding window for Slack batch images, Feishu documents, Telegram URL-photo fallback, and WeCom remote media.
Route each path through create_ssrf_safe_async_client and the shared redirect guard so direct connections validate and dial vetted IPs while configured proxies remain an explicit trusted egress boundary. Add per-path regressions that change DNS from public at preflight to metadata at connect time.
The Skills Hub provenance fixture intentionally serves content over loopback. Opt that test-scoped server into private-address access so it keeps exercising the real HTTP transport without weakening production blocking.

Removes Homebrew and PyPI wheel/sdist as Hermes distribution paths while
preserving the supported source, Docker, and Nix workflows.
Changes:
- Removes the Homebrew formula, PyPI publish workflow, sdist manifest
(MANIFEST.in), and wheel/sdist release-attachment logic from scripts/release.py.
- Keeps setuptools metadata and entry points required by editable installs
and Docker/Nix builds, but adds a setup.py guard that rejects wheel/sdist
builds outside a sealed Nix derivation (HERMES_NIX_BUILD=1).
- Removes pip/Homebrew install detection, PyPI update checks, the pip
self-update path, the deprecation-banner state, the postinstall subcommand,
wheel data-directory fallbacks in agent/i18n.py and hermes_constants.py,
and the ACP Registry manifest/version-lockstep release logic.
- Adds /nix/store/ path detection so `nix run` / `nix profile install`
installs (which don't set HERMES_MANAGED) are correctly identified as
"nix" rather than falling through to "git"/"unknown".
- Retired install-method values ("pip", "homebrew") in existing
.install_method stamps (both code-scoped and home-scoped) are ignored by
the allowlist reader and fall through to "unknown" instead of resurrecting
a retired enum value.
- Updates Nix packaging to ship bare runtime data (locales, optional-mcps)
through store symlinks and wrapper env vars instead of wheel data-files.
- Removes the ACP Registry manifest/icon and their version-lockstep tests.
- Deletes or rewrites packaging, pip-update, Homebrew, and ACP Registry
tests; adds parametrized coverage for the packaging build guard covering
BOTH sdist and wheel paths (the guards live in separate cmdclass entries
— a passing sdist test proves nothing about the wheel path).
- Updates installation/platform documentation and related user-facing copy.
- Adjusts the supply-chain scan so deleted install-hook files do not trigger
a finding, while additions or modifications still require the existing
ci-reviewed label gate.
Supported installation paths (unchanged):
- git installer (install.sh)
- Docker
- Nix/NixOS
- editable development installs (uv sync, uv pip install -e ., pip install -e .)
A platform with a missing dependency or missing credentials can never
succeed on retry, but connect() returned bare False, so the gateway
treated the failure as transient and queued it for background
reconnection — looping forever at the backoff cap. Set
_set_fatal_error(..., retryable=False) for missing-dependency and
missing-credential failures in the Slack, Telegram, and Discord
adapters so the reconnect watcher drops them from the retry queue.

Widen the allow_session tier from Matrix to every adapter the gateway
notifies: Telegram, Discord, Slack, Feishu, and Teams gate their Session
button on it; WhatsApp Cloud and qqbot accept the kwarg (no session tier
in their button sets). Also thread allow_session through the plugin-
escalation gate, the execute_code guard payload, and the plain-text
fallback so every notify path carries the same capability flags.
Three related messaging-approval fixes:
1. approvals.timeout default 60 -> 300. PR #63501 collapsed the gateway
wait onto the canonical approvals.timeout (previously
gateway_timeout=300), silently shrinking messaging approval windows
to 60s. Push-notification approvals routinely arrive later than a
minute; taps landed after the wait had already failed closed.
2. Stale-tap honesty: adapters resolved the approval AFTER rendering
'<checkmark> Approved by <user>' (Telegram/Discord/Slack), or ignored a zero
resolve count (WhatsApp Cloud/Feishu). A tap on an expired prompt
claimed approval while the command had already been denied. All
button paths now resolve first and render 'Approval expired -
command was not run' when nothing was waiting.
3. Mixed-warning prompts (dangerous pattern + tirith finding) now offer
Always: the persistence layer already permanently allowlists the
pattern key and downgrades the tirith key to session scope, but the
UI hid Always whenever ANY tirith warning was present. Pure-tirith
prompts still withhold Always (content findings are session-max by
design), and Smart-DENY overrides remain once-only.
The wedged-recovery heartbeat watchdog (line 2526) calls
_notify_fatal_error() directly from the heartbeat task. disconnect()
cancels _polling_heartbeat_task unconditionally (no current_task guard,
unlike _polling_error_task). Same bug class as #68406: the child
disconnect cancels the heartbeat parent before the runner can queue
reconnect.
Widen _handoff_polling_fatal_error() to also clear
_polling_heartbeat_task when it is the current task, and route the
heartbeat watchdog call site through the handoff helper.
Co-authored-by: Imgaojp <6065749+Imgaojp@users.noreply.github.com>
Release the current polling-recovery task's ownership before invoking
the fatal-error handler. The runner bounds adapter cleanup in a child
task; disconnect() cancels the tracked polling-recovery task, so
retaining the current notifier in _polling_error_task would cancel the
fatal callback before the runner can finish its reconnect-queue or
shutdown decision.
The new _handoff_polling_fatal_error() helper clears
_polling_error_task only when it is the current notifier. Other
recovery tasks remain tracked and are still cancelled and awaited
during teardown.
Covers both network retry exhaustion and polling-conflict exhaustion.
Replaces the misleading "Restarting gateway" message with "Escalating
to gateway recovery".
Fixes#68406.
The Telegram gateway could go silently deaf for hours: the reconnect ladder
stalled mid-way (e.g. "attempt 4/10, reconnecting in 40s" then nothing) while
the process stayed active(running), so Restart=always never fired.
Root class: every recovery path — the ladder's re-entry
(_schedule_polling_recovery), the pending-update probe (_probe_pending_updates),
and PTB's error callback — gates new recovery on _polling_error_task.done(). If
that single task wedges on any hung await, all recovery returns early forever
and nothing retries.
The heartbeat loop is a separate task, so make it an independent, cause-agnostic
watchdog: if the same recovery task stays in-flight past
_POLLING_ERROR_TASK_STUCK_TIMEOUT (300s — well beyond a healthy ladder attempt's
bounded stop+drain+start+backoff), force a retryable-fatal so the background
reconnector rebuilds the adapter instead of relying on the frozen ladder. This
guarantees progress regardless of *where* the stall is (issue direction #1),
tracked locally so no task-assignment site needs to change.
Also salvages @koduri-mahesh-bhushan-chowdary's #66492 (drain-await timeout),
which closes the one concrete wedge vector documented in the incident
(_drain_polling_connections' unbounded shutdown()/initialize() on a wedged
CLOSE-WAIT pool). The watchdog covers the rest of the class.

_drain_polling_connections() awaited polling_req.shutdown() and
.initialize() without a timeout. When the getUpdates httpx connection is
wedged on a stale CLOSE-WAIT socket, that close can block forever, hanging
_handle_polling_network_error (the tracked _polling_error_task). The task
never completes, so every escalation path — _schedule_polling_recovery,
_probe_pending_updates, the heartbeat verifier — stays gated behind its
in-flight guard, the ladder freezes mid-way, _set_fatal_error is never
reached, and Restart=always never fires: the gateway is alive but silently
dead.
Wrap both drain awaits in asyncio.wait_for with a new module-level
_DRAIN_TIMEOUT (15.0s, matching _UPDATER_STOP_TIMEOUT), mirroring the
existing bounded stop()/start_polling() sites. On timeout the drain logs and
continues, so the handler task completes and the ladder always advances
toward the fatal-restart escalation.
Adds test_reconnect_continues_if_drain_hangs, which wedges the drain and
asserts the handler still reaches start_polling within a hard bound.

Bare /reasoning and /fast now render a native one-tap picker on
picker-capable platforms, with automatic fallback to the text status
card everywhere else — parity with the /model picker UX.
- gateway/slash_commands.py: generic send_choice_picker capability gate
(detected on the adapter type, like send_model_picker); selection and
typed arguments flow through one shared application path so they can
never diverge; choices built from VALID_REASONING_EFFORTS so future

- telegram: flat inline-keyboard picker (cp:<idx> callbacks), authorized
users only (same gate as approval buttons)
- discord: ChoicePickerView select menu, auth mirrors ExecApprovalView,
2-minute timeout with expiry edit

Telegram only auto-derives a voice/audio clip's duration from container
metadata for short recordings; clips longer than ~4:50 are delivered with
duration 0 and render as 0:00 in the player. Probe the length locally
(stdlib wave -> mutagen -> ffprobe) and pass duration explicitly to
sendVoice/sendAudio. Best-effort: when nothing can read the file we omit
duration and fall back to Telegram's prior behavior.
Extracts and hardens the Telegram-only part of the stale, Piper-bundled
PR #7815 (ffprobe-only, predates the send_voice retry/anchor refactor);
relates to #8508.
Extends @AlexFucuson9's 3-site fix (#58594) across the full adapter:
every logger call and SendResult.error that interpolates a raw PTB
exception now routes through _redact_telegram_error_text(). Covers
polling conflict/retry/network ladders, overflow-split edits, draft
sends, prompt/approval/clarify/picker sends, media send fallbacks,
media cache failures, reactions, and chat-info lookups (48 additional
sites). Telegram Bot API exceptions embed the token in the request URL
(/bot<TOKEN>/<method>), so any raw str(exc) is a leak surface.
Adds regression tests for SendResult.error redaction (update prompt,
clarify) and delete_message debug-log redaction.
Telegram Bot API URLs carry credentials in the path as
/bot<TOKEN>/<method>. Three error-handling paths logged raw exception
text that could include these URLs:
- sendRichMessage fallback (line 1603)
- editMessageText fallback (line 1709)
- polling reconnect warning (line 1902)
Replace raw / with which
uses the existing redact_sensitive_text(force=True) pipeline. This
matches the pattern already used by transient send failures, retry
errors, and legacy edit paths.
Fixes#58376
Follow-ups on the salvaged #20096 profile-routing feature:
- _profile_name_for_source now returns None unless gateway.multiplex_profiles
is on. Routing stamps source.profile, which namespaces session/batch keys,
but the profile-scoped agent run only activates under multiplexing — without
the gate, configured routes with multiplexing off split batch/session keys
into agent:<profile> while the agent still ran from agent:main.
- Widen the profile-aware _text_batch_key fix from Discord to every adapter
that builds batch keys via build_session_key (telegram, whatsapp, matrix,
feishu, wecom, weixin) — routing is platform-generic, so the batch-key
namespace fix must be too.
- Downgrade the no-route-matched log from INFO to DEBUG (fired on every
unrouted inbound message).
- GatewayConfig.to_dict(): serialize profile_routes as plain dicts
(ProfileRoute dataclasses are not JSON-safe).
- Docs: correct the 'independent of multiplexing' claim in
docs/profile-routing.md (routing requires multiplexing), fix the
platform-only specificity row (0, not 1), and document profile_routes in
website/docs/user-guide/multi-profile-gateways.md.
- Tests: pin the multiplex gate (routes ignored when off, active when on,
build_source end-to-end stays in agent:main when off).
PTB's HTTPXRequest/BaseRequest use __slots__. On Python 3.13 their
instances no longer carry a __dict__, so the getUpdates progress
instrumentation's `request.do_request = wrapper` monkey-patch raises
`AttributeError: 'HTTPXRequest' object attribute 'do_request' is
read-only`, failing every Telegram connect (#64482). It only worked on
Python 3.12, where the instance still had a __dict__ — the Docker image
ships Python 3.13, so the release broke Telegram outright.
Re-tag the request to a thin `__slots__ = ()` subclass that overrides
do_request instead of mutating the instance. This preserves the exact
progress-observation semantics, works on both 3.12 and 3.13, and covers
the real request and the test doubles alike.
After #53825's fix removed the auto-rich table bypass from
_rich_delivery_enabled(), _content_is_pipe_table_primary() had zero
callers. Remove it and simplify _rich_delivery_enabled() to the bare
rich_messages opt-in check (content param no longer used).
Remove the pipe-table bypass from _rich_delivery_enabled() so that
rich_messages: false is fully honoured. Previously, pipe tables were
auto-routed to sendRichMessage regardless of the config flag, breaking
delivery on clients without Bot API 10.1 support (AyuGram, Telegram
Web, some desktop clients).
Fixes#53824
The #63309 hang class — gateway stuck at 'Connecting to Telegram
(attempt 1/8)' with no retry, no timeout, for minutes — can only occur
when the event loop thread itself is blocked in a synchronous call:
_await_with_thread_deadline's timer fires off-loop, but its expiry
hand-off (call_soon_threadsafe) still needs the loop to run, and the
gateway's outer wait_for is a pure loop timer. When the loop is pinned,
every layer goes silent simultaneously and the process wedges with no
evidence of where.
Two changes:
1. Loop-blocked watchdog in _await_with_thread_deadline: a second
daemon timer fires one grace period (5s) after the deadline; if the
loop still hasn't processed the expiry, it logs a WARNING from the
timer thread and faulthandler-dumps all thread stacks to stderr —
converting the silent hang into a trace that names the exact
blocking frame. A threading.Event set by the expiry callback (and on
normal exit) keeps completed awaits from ever being misreported.
2. discover_fallback_ips: the system-resolver leg runs
socket.getaddrinfo in a worker thread with no timeout, and
asyncio.gather waited on it unboundedly — a wedged OS resolver
stalled discovery for minutes between the two startup log lines. Its
result only feeds a log message, so it no longer gates discovery:
DoH legs (already client-bounded) are gathered alone and the system
leg is awaited with a _DOH_TIMEOUT cap, best-effort.
Refs #63309
Tests: 3 watchdog regressions (blocked-loop dump fires; responsive-loop
timeout does not; completed await does not) + 2 hung-resolver
regressions (DoH results returned promptly; worst-case seed fallback
stays bounded).
Keep empty-tail recovery scoped to the current stream segment and bound fallback flood retries. Preserve Telegram's server retry hint without blocking final delivery through a long cooldown.
Follow-up on the salvaged fix, which bounded start_polling() only in
_handle_polling_network_error. The same wedge (#59614) exists at the two
sibling call sites:
1. _start_polling_resilient (bootstrap): an exhausted pool hangs connect()
forever. The TimeoutError from wait_for is a builtins TimeoutError
(OSError subclass), so the existing except classifies it via
_looks_like_network_error and schedules background recovery.
2. _handle_polling_conflict (conflict-retry ladder): identical hang wedges
conflict attempt N forever; timeout now converts to RuntimeError and the
existing except schedules the next attempt.
Tests replaced with a stronger suite: hung-network-ladder repro (RED without
the fix), bootstrap hang schedules recovery, success-path sanity, and a
bug-class contract test asserting EVERY updater.start_polling( call site is
wrapped in wait_for so a new unbounded site can't reintroduce the wedge.
Verified RED (3 failures) with the wrappers removed, GREEN with them.
When the connection pool is in a degraded state after
_drain_polling_connections(), start_polling() can hang indefinitely
when both primary and fallback Telegram endpoints are unreachable. The
httpx client may hold a stale socket that neither connects nor times out
within PTB's internal flow, causing the reconnect ladder to stall at
attempt 1/10 forever.
Wrap start_polling() in asyncio.wait_for() with a 30-second timeout so a
hung call raises asyncio.TimeoutError and feeds back into the existing
retry ladder. This unblocks:
- The 10-retry ladder advances to attempt 2, 3, ...
- The heartbeat loop sees _polling_error_task.done() and can trigger recovery
- The reconnect watcher gets the adapter in _failed_platforms
Fixes#59614
* fix: cool down transient Telegram typing failures
Port from openclaw/openclaw#93020: add per-chat cooldown for transient sendChatAction failures so keep-typing refreshes do not hammer Telegram during network blips or rate limits.
* fix: support bare Telegram adapters in typing cooldown
* test: update typing backoff imports for relocated Telegram adapter
The Telegram adapter moved from gateway/platforms/telegram.py to
plugins/platforms/telegram/adapter.py since this branch was created;
point the test imports and monkeypatch targets at the new module.
_redact_telegram_error_text() strips bot tokens from api.telegram.org
URLs embedded in transport-error text, and is already applied across the
send/edit transient-error paths. Four sites still built their message
from the raw exception:
- connect()'s fatal-error handler is the most severe: the raw text is
passed to _set_fatal_error(), which persists it via
write_runtime_status() to a dashboard/admin-facing runtime status
file, not just a log line. A transient network error during startup
commonly embeds the request URL
(https://api.telegram.org/bot<TOKEN>/getMe), so this could leak the
live bot token into that surface.
- disconnect(), send_document(), send_video() build the same unredacted
pattern into a warning log line (lower blast radius, but the same
leak class).
Fix: route all four through the existing _redact_telegram_error_text()
helper before building the message/log line, mirroring the send/edit
paths exactly. Also drops exc_info=True from the two logger.error/
logger.warning calls that had it — exc_info prints the exception's own
traceback (including its unredacted message) separately from the format
string, which would otherwise defeat the redaction; the already-redacted
sibling call sites in this file follow the same convention.
The unreadable-config-overwrite bug (an existing config.yaml that reads as
{} on a permission/IO error gets replaced with only defaults or the edited
section) is not limited to save_config / config set / auth. The same
read-then-atomic_yaml_write pattern lives at ~7 other independent write
sites that don't route through those functions:
- gateway/slash_commands.py: _save_config_key, memory/skills write_approval
toggles, tool_progress toggle, runtime_footer toggle, personality set
- hermes_cli/doctor.py --fix (stale root-key migration)
- gateway/platforms/yuanbao.py auto-sethome
- plugins/platforms/telegram/adapter.py topic thread_id persistence
- tui_gateway/server.py _save_cfg
- agent/onboarding.py mark_seen
Rather than sprinkle require_readable_config_before_write() at each site,
add a single fail-closed chokepoint, atomic_config_write(), that runs the
guard then delegates to atomic_yaml_write, and route every config.yaml
write through it. Root cause remains that read_raw_config() can't tell an
absent file from an unreadable one (returns {} for both) — read-only
callers correctly stay fail-open, but any full-file replacement now fails
closed in one enforced place instead of relying on each caller to remember
the guard.
save_config / set_config_value / auth keep the contributor's original
guard calls (their commit); this commit widens the fix to the sibling
call paths and adds a regression test on the chokepoint (fails closed on
unreadable existing file + still creates a genuinely absent file).
Follow-up on the #58790 fallback-limits fix: tighten the now-stale
_with_limits docstring and note on the fallback branch why it injects
limits at the transport level (not via _with_limits) so a future editor
does not re-route it through the client-level helper httpx would discard.
httpx ignores the client-level `limits` kwarg when a custom `transport`
is supplied. The #31599 keepalive fix injected limits via
`httpx_kwargs[limits]`, but the fallback-IP branch also passes a
custom `TelegramFallbackTransport` — so the limits were silently
discarded and the inner AsyncHTTPTransport instances ran with httpx
defaults (keepalive_expiry=5.0), leaking CLOSE_WAIT fds.
Pass the tuned limits directly into `TelegramFallbackTransport`
via `transport_kwargs` so its inner transports honour keepalive_expiry.
Only affects the fallback-IP branch; proxy and direct-DNS branches
continue to use `_with_limits()` as before.
Fixes#58790
Post-#48648, oversized mid-stream edits truncate to a 4096-char preview
instead of splitting. But when rich messages raise the consumer's overflow
budget to 32k, the consumer keeps accumulating past 4096 and keeps issuing
progressive edits every edit_interval — each one truncating to the SAME
preview text. Telegram counts every one of those no-op requests against the
flood budget: a long streamed reply fires ~1 identical edit per 0.8s for
the rest of the stream, trips flood control (200s+ penalties), and the
final delivery hangs behind inline flood sleeps. Users see the bot stuck
'streaming' and the chat unresponsive.
Fix at the chokepoint: track the last truncated preview per
(chat_id, message_id) and skip the API call when the new truncation is
identical. Previews still update when the visible prefix actually changes
(e.g. chunk-count marker 1/2 → 1/3). State clears on finalize and when
content shrinks back under the cap, so dedup can never mask a real edit.
Live repro: 19,956-char streamed reply, transport=edit, rich available —
4x flood-control hits within ~700ms, 250s penalties, hung final delivery.
E2E harness on the same stream: 14 edit calls on main vs 7 with the fix
(the delta is pure no-op duplicates; scales with stream length).
The salvaged fix (#58272) guarded the primary network-error reconnect path.
Issue #58270's Scope section names three more unguarded await updater.stop()
sites that can hang identically on a CLOSE-WAIT socket:
- conflict handler (before the retry back-off sleep)
- conflict-retries-exhausted teardown (before the fatal notify)
- disconnect() teardown (would hang gateway shutdown/restart)
Each is now wrapped in asyncio.wait_for(..., _UPDATER_STOP_TIMEOUT) with a
warning on timeout, matching the primary path, so no reconnect/teardown ladder
can wedge on a dead socket.
Also hoist the shared 15.0s bound to a single module constant
_UPDATER_STOP_TIMEOUT (self-documenting + DRY across all 4 sites), and update
the CLOSE-WAIT regression test to patch that constant instead of monkeypatching
asyncio.wait_for process-wide.
Fatal-notify idempotency: bounding the conflict-exhausted teardown stop() adds
an await AFTER _set_fatal_error, which yields the loop and lets a concurrent
retry task (scheduled by an earlier conflict, already suspended past the entry
guard) reach the fatal branch too — double-firing the fatal handler (surfaced
as a Python 3.11 CI failure in test_polling_conflict_becomes_fatal_after_retries).
Snapshot the pre-transition fatal state and only notify on the first transition.
When the TCP connection enters CLOSE-WAIT the PTB polling task is blocked
on epoll on a dead socket and never wakes. updater.stop() awaits that task
and therefore hangs indefinitely.
Consequence: _polling_error_task stays alive-but-blocked forever; every
subsequent heartbeat probe sees it as "in-flight" and skips triggering a
new reconnect; the gateway silently drops messages for hours until a manual
restart. Field incident: 11-hour outage on 2026-07-04 UTC despite the
heartbeat loop firing a reconnect at 01:11 — stop() blocked the entire
ladder.
Fix: wrap the updater.stop() call inside asyncio.wait_for(timeout=15).
On TimeoutError log a warning and continue to _drain_polling_connections()
+ start_polling() — same recovery path, just unblocked.
The heartbeat loop (PR #48496) correctly detects the dead socket and fires
_handle_polling_network_error. This commit is the missing second half:
ensuring the reconnect itself always completes.
Test: test_handle_polling_network_error_updater_stop_timeout() simulates
a hang by making stop() sleep forever and verifies that drain + start_polling
are still reached after the timeout.
Fixes#58270
Follow-up to @msh01's wall-deadline init-timeout fix.
- Resource leak: on timeout the initialize() task is abandoned without
awaiting its (shielded, possibly-never-completing) cancellation, so the
half-built PTB app's httpx client / connection pool was never closed —
up to 8x across the retry ladder. Add an optional on_abandon cleanup to
_await_with_thread_deadline that best-effort app.shutdown()s the abandoned
app, run detached + exception-swallowed so it can never re-block or re-hang
the ladder (mirrors _close_client_on_timeout in agent/auxiliary_client.py).
- Cover the helper itself: the salvaged test monkeypatched out the real
_await_with_thread_deadline, so its abandonment/cleanup path was untested.
Add direct tests for happy-path return, prompt-timeout-with-cleanup, and
cleanup-error-swallowed; the wedged coroutines swallow cancellation for a
bounded window (proving the helper returns before cancellation completes,
the #58236 shielded-scope behavior) without leaving an immortal task that
would wedge pytest teardown. Widen the salvaged stub to accept on_abandon.
- Attribution: add yingwaizhiying@gmail.com -> msh01 to AUTHOR_MAP (bare
gmail does not auto-resolve the check-attribution gate).
Known follow-up (not addressed here): the retry ladder reuses the same
self._app across all 8 attempts; a fresh app per attempt would fully close
the coherence risk if an abandoned initialize() completes in the background.
That is a larger restructure of the ~130-line builder+handler setup, left
for a separate change.
Wrap each Telegram initialize() attempt in asyncio.wait_for(HERMES_TELEGRAM_INIT_TIMEOUT,
default 30s). When api.telegram.org and all fallback IPs are unreachable, the connect
chain has no outer bound, so a single initialize() blocks for minutes and the
retry-on-exception loop never fires — the gateway appears to hang after the banner.
The timeout guarantees each attempt is bounded, then retries with backoff, then fails
with an actionable error. Also adds WARNING-level progress logs before DoH discovery
and each connect attempt (visible at default log level).
Salvaged onto plugins/platforms/telegram/adapter.py (Telegram moved from
gateway/platforms/ since the PR was opened). Adds env var to docs + AUTHOR_MAP.
