Three fixes that close the remaining structural sources of CI flakes
after PR #13363.
## 1. Per-test reset of module-level singletons and ContextVars
Python modules are singletons per process, and pytest-xdist workers are
long-lived. Module-level dicts/sets and ContextVars persist across tests
on the same worker. A test that sets state in `tools.approval._session_approved`
and doesn't explicitly clear it leaks that state to every subsequent test
on the same worker.
New `_reset_module_state` autouse fixture in `tests/conftest.py` clears:
- tools.approval: _session_approved, _session_yolo, _permanent_approved,
_pending, _gateway_queues, _gateway_notify_cbs, _approval_session_key
- tools.interrupt: _interrupted_threads
- gateway.session_context: 10 session/cron ContextVars (reset to _UNSET)
- tools.env_passthrough: _allowed_env_vars_var (reset to empty set)
- tools.credential_files: _registered_files_var (reset to empty dict)
- tools.file_tools: _read_tracker, _file_ops_cache
This was the single biggest remaining class of CI flakes.
`test_command_guards::test_warn_session_approved` and
`test_combined_cli_session_approves_both` were failing 12/15 recent main
runs specifically because `_session_approved` carried approvals from a
prior test's session into these tests' `"default"` session lookup.
## 2. Unset platform allowlist env vars in hermetic fixture
`TELEGRAM_ALLOWED_USERS`, `DISCORD_ALLOWED_USERS`, and 20 other
`*_ALLOWED_USERS` / `*_ALLOW_ALL_USERS` vars are now unset per-test in
the same place credential env vars already are. These aren't credentials
but they change gateway auth behavior; if set from any source (user
shell, leaky test, CI env) they flake button-authorization tests.
Fixes three `test_telegram_approval_buttons` tests that were failing
across recent runs of the full gateway directory.
## 3. Two specific tests with module-level captured state
- `test_signal::TestSignalPhoneRedaction`: `agent.redact._REDACT_ENABLED`
is captured at module import from `HERMES_REDACT_SECRETS`, not read
per-call. `monkeypatch.delenv` at test time is too late. Added
`monkeypatch.setattr("agent.redact._REDACT_ENABLED", True)` per
skill xdist-cross-test-pollution Pattern 5.
- `test_internal_event_bypass_pairing::test_non_internal_event_without_user_triggers_pairing`:
`gateway.pairing.PAIRING_DIR` is captured at module import from
HERMES_HOME, so per-test HERMES_HOME redirection in conftest doesn't
retroactively move it. Test now monkeypatches PAIRING_DIR directly to
its tmp_path, preventing rate-limit state from prior xdist workers
from letting the pairing send-call be suppressed.
## Validation
- tests/tools/: 3494 pass (0 fail) including test_command_guards
- tests/gateway/: 3504 pass (0 fail) across repeat runs
- tests/agent/ + tests/hermes_cli/ + tests/run_agent/ + tests/tools/:
8371 pass, 37 skipped, 0 fail — full suite across directories
No production code changed.
base.py's _keep_typing refresh loop calls send_typing every ~2s while
the agent is processing. If signal-cli returns NETWORK_FAILURE for the
recipient (offline, unroutable, group membership lost), the unmitigated
path was a WARNING log every 2 seconds for as long as the agent stayed
busy — a user report showed 1048 warnings in 41 minutes for one
offline contact, plus the matching volume of pointless RPC traffic to
signal-cli.
- _rpc() accepts log_failures=False so callers can route repeated
expected failures (typing) to DEBUG while keeping send/receive at
WARNING.
- send_typing() tracks consecutive failures per chat. First failure
still logs WARNING so transport issues remain visible; subsequent
failures log at DEBUG. After three consecutive failures we skip the
RPC during an exponential cooldown (16s, 32s, 60s cap) so we stop
hammering signal-cli for a recipient it can't deliver to. A
successful sendTyping resets the counters.
- _stop_typing_indicator() clears the backoff state so the next agent
turn starts fresh.
E2E simulation against the reported 41-minute window: RPCs drop from
1230 to 45 (-96%), log lines from 1048 WARNINGs to 1 WARNING + 44
DEBUGs.
Credits kshitijk4poor (#12056) for the _rpc log_failures kwarg idea;
the broader restructure in that PR (nested per-chat loop inside
send_typing) is avoided here in favour of stateful backoff that
preserves base.py's existing _keep_typing architecture.
First pass of test-suite reduction to address flaky CI and bloat.
Removed tests that fall into these change-detector patterns:
1. Source-grep tests (tests/gateway/test_feishu.py, test_email.py): tests
that call inspect.getsource() on production modules and grep for string
literals. Break on any refactor/rename even when behavior is correct.
2. Platform enum tautologies (every gateway/test_X.py): assertions like
`Platform.X.value == 'x'` duplicated across ~9 adapter test files.
3. Toolset/PLATFORM_HINTS/setup-wizard registry-presence checks: tests that
only verify a key exists in a dict. Data-layout tests, not behavior.
4. Argparse wiring tests (test_argparse_flag_propagation, test_subparser_routing
_fallback): tests that do parser.parse_args([...]) then assert args.field.
Tests Python's argparse, not our code.
5. Pure dispatch tests (test_plugins_cmd.TestPluginsCommandDispatch): patch
cmd_X, call plugins_command with matching action, assert mock called.
Tests the if/elif chain, not behavior.
6. Kwarg-to-mock verification (test_auxiliary_client ~45 tests,
test_web_tools_config, test_gemini_cloudcode, test_retaindb_plugin): tests
that mock the external API client, call our function, and assert exact
kwargs. Break on refactor even when behavior is preserved.
7. Schedule-internal "function-was-called" tests (acp/test_server scheduling
tests): tests that patch own helper method, then assert it was called.
Kept behavioral tests throughout: error paths (pytest.raises), security
tests (path traversal, SSRF, redaction), message alternation invariants,
provider API format conversion, streaming logic, memory contract, real
config load/merge tests.
Net reduction: 169 tests removed. 38 empty classes cleaned up.
Collected before: 12,522 tests
Collected after: 12,353 tests
Fixes#4647 — Signal replies duplicated when gateway streaming is enabled.
Root cause: stream_consumer.py did not handle the case where send() returns
success=True but no message_id (Signal behavior). Every stream delta produced
a separate send() call (7+ messages instead of 2), plus the gateway sent
another full duplicate since already_sent was never set.
Changes:
- stream_consumer.py: Add elif branch for success-without-message_id — enters
fallback mode (sets already_sent, disables editing, sends only continuation)
- signal.py send(): Extract timestamp from signal-cli RPC result as message_id
so stream consumer follows normal edit→fallback path
- signal.py: Add public stop_typing() delegating to _stop_typing_indicator()
so base adapter's _keep_typing finally block can clean up typing tasks
- gateway/run.py: Per-platform tool_progress_overrides (#6164) — lets users
set e.g. signal: off while keeping telegram: all
- hermes_cli/config.py: Add tool_progress_overrides to DEFAULT_CONFIG
Refs: #4647, #6164
The Signal adapter inherited base class defaults for send_image_file(),
send_voice(), and send_video() which only sent the file path as text
(e.g. '🖼️ Image: /tmp/chart.png') instead of actually delivering the file
as a Signal attachment.
When agent responses contain MEDIA:/path/to/file tags, the gateway
media pipeline extracts them and routes through these methods by file
type. Without proper overrides, image/audio/video files were never
actually delivered to Signal users.
Extract a shared _send_attachment() helper that handles all file
validation, size checking, group/DM routing, and RPC dispatch. The four
public methods (send_document, send_image_file, send_voice, send_video)
now delegate to this helper, following the same pattern used by WhatsApp
(_send_media_to_bridge) and Discord (_send_file_attachment).
The helper also uses a single stat() call with try/except FileNotFoundError
instead of the previous exists() + stat() two-syscall pattern, eliminating
a TOCTOU race. As a bonus, send_document() now gains the 100MB size check
that was previously missing (inconsistency with send_image).
Add 25 tests covering all methods plus MEDIA: tag extraction integration,
method-override guards, and send_document's new size check.
Fixes#5105
Fixes two Signal bugs:
1. SSE connection: URL-encode phone numbers so + isn't interpreted as space (400 Bad Request)
2. Attachment fetch: use 'id' parameter instead of 'attachmentId' (NullPointerException in signal-cli)
Also refactors Signal tests with shared helpers.
- test_plugins.py: remove tests for unimplemented plugin command API
(get_plugin_command_handler, register_command never existed)
- test_redact.py: add autouse fixture to clear HERMES_REDACT_SECRETS
env var leaked by cli.py import in other tests
- test_signal.py: same HERMES_REDACT_SECRETS fix for phone redaction
- test_mattermost.py: add @bot_user_id to test messages after the
mention-only filter was added in #2443
- test_context_token_tracking.py: mock resolve_provider_client for
openai-codex provider that requires real OAuth credentials
Full suite: 5893 passed, 0 failed.
Complete Signal adapter using signal-cli daemon HTTP API.
Based on PR #268 by ibhagwan, rebuilt on current main with bug fixes.
Architecture:
- SSE streaming for inbound messages with exponential backoff (2s→60s)
- JSON-RPC 2.0 for outbound (send, typing, attachments, contacts)
- Health monitor detects stale SSE connections (120s threshold)
- Phone number redaction in all logs and global redact.py
Features:
- DM and group message support with separate access policies
- DM policies: pairing (default), allowlist, open
- Group policies: disabled (default), allowlist, open
- Attachment download with magic-byte type detection
- Typing indicators (8s refresh interval)
- 100MB attachment size limit, 8000 char message limit
- E.164 phone + UUID allowlist support
Integration:
- Platform.SIGNAL enum in gateway/config.py
- Signal in _is_user_authorized() allowlist maps (gateway/run.py)
- Adapter factory in _create_adapter() (gateway/run.py)
- user_id_alt/chat_id_alt fields in SessionSource for UUIDs
- send_message tool support via httpx JSON-RPC (not aiohttp)
- Interactive setup wizard in 'hermes gateway setup'
- Connectivity testing during setup (pings /api/v1/check)
- signal-cli detection and install guidance
Bug fixes from PR #268:
- Timestamp reads from envelope_data (not outer wrapper)
- Uses httpx consistently (not aiohttp in send_message tool)
- SIGNAL_DEBUG scoped to signal logger (not root)
- extract_images regex NOT modified (preserves group numbering)
- pairing.py NOT modified (no cross-platform side effects)
- No dual authorization (adapter defers to run.py for user auth)
- Wildcard uses set membership ('*' in set, not list equality)
- .zip default for PK magic bytes (not .docx)
No new Python dependencies — uses httpx (already core).
External requirement: signal-cli daemon (user-installed).
Tests: 30 new tests covering config, init, helpers, session source,
phone redaction, authorization, and send_message integration.
