Three test files (test_auth_regressions, test_auth_event_loop,
test_null_owner_gates) install stubs for core.database / core.auth /
src.endpoint_resolver at module-import time, so they outlive the
file and are still present in sys.modules when later-collected test
files try to import the real modules. The stubs are minimal (a
handful of MagicMock attrs) so the import chain that follows fails
with ImportError on the very next real import.
test_companion_pairing also leaks, with a twist: its _DBStub
subclass returns a MagicMock for *any* attribute including dunders,
so the next test that does `from core.database import *` reads
`__all__` as a MagicMock and dies with 'Item in __all__ must be
str, not MagicMock'.
Move the stub installation into an autouse fixture per file and
register each stub with monkeypatch.setitem so sys.modules is
restored to its pre-test state on teardown. Tighten _DBStub to
refuse dunder names so __all__ stays undefined. _CAPTURED is
cleared per test so the mint-token assertions see a fresh dict.
Before: 3 test files fail at collection time (test_chat_image_routing,
test_context_compactor, test_webhook_ssrf_resilience). After: 0
collection errors. 1365/1370 pass, 1 skip, 4 unrelated pre-existing
failures (verified against origin/main baseline).
Out of scope: test_task_scheduler_session_delivery::
test_session_delivery_survives_empty_database also fails in the
full suite due to order-dependent state from a different test
file. That's a separate leak with a different root cause.
* fix: run bcrypt off the event loop in auth routes
The auth routes are async, but each bcrypt call ran synchronously on the event
loop. bcrypt (checkpw/hashpw) is intentionally CPU-expensive (~100-300 ms), so
every login / signup / setup / change-password froze the single event loop for
that window, stalling all other in-flight requests (chat streams, polling, ...).
/api/auth/login is the worst case: it is reachable unauthenticated, runs bcrypt
twice (verify_password, then create_session re-verifies), and is rate-limited
only per-IP. A burst of login attempts serializes the whole server — cheap
DoS amplification.
Offload the bcrypt-bearing AuthManager calls (setup, signup/create_user,
login's verify_password + create_session, change_password) via
asyncio.to_thread, matching how the codebase already offloads blocking work
(e.g. src/builtin_actions._run_subprocess, email summarize). The event loop
stays responsive while bcrypt runs on a worker thread.
Add tests/test_auth_event_loop.py: asserts login runs verify_password and
create_session on a worker thread, not the loop thread. Fails if those calls
are awaited inline again.
* test: isolate auth event-loop test from heavy core/* import chain
The regression test imported routes.auth_routes, which pulls in
core.auth and so triggers core/__init__.py — transitively importing
src.llm_core (hangs at import under the project venv) and the SQLAlchemy
declarative models (metaclass error on a bare core.database import / under
the conftest sqlalchemy stubs). Reported by the maintainer: collection
failed on system Python and hung under the venv.
Stub core.auth/core.database before the import, mirroring the existing
_ensure_stub pattern in test_auth_regressions.py and test_null_owner_gates.py.
AuthManager is only a type hint here and the handler is exercised with a
MagicMock, so no real core machinery is needed. Test now imports cleanly
and passes in <0.3s without bcrypt/sqlalchemy installed.
