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.
Split 3/4 of the companion bridge (#863, #871 landed 1/4 and 2/4). Adds admin-only
device pairing to the companion router.
- GET /api/companion/pair -- renders a form; never mints (a GET must not mint a
credential: SameSite=Lax session cookies ride top-level GET navigations, so
GET-minting would be CSRF-triggerable via a link/<img>)
- POST /api/companion/pair -- mints a one-time chat-scoped token. Admin-cookie
only; CSRF-safe because a SameSite=Lax cookie is not sent on a cross-site POST,
the same protection POST /api/tokens relies on. ?format=json returns the
pairing payload for an in-app screen.
Minting invalidates the auth middleware's token cache so the code works on the
next request with no restart. companion/pairing.py holds the mint/LAN/QR helpers;
the token is shown once and stored only as a bcrypt hash + prefix
(mirrors routes/api_token_routes.py).
Tests (tests/test_companion_pairing.py):
- a bearer/'api' caller and a non-admin user are rejected by require_admin (403);
an admin passes
- the token is returned once and persisted only as a hash
- minting invalidates the cache (works without restart)
- minting is exposed on POST, never GET (CSRF)
