<observations> Date: Aug 4, 2026 * 🟡 (19:42) Assistant created symlink `/home/byk/Code/getsentry/getsentry/.venv -> /home/byk/Code/getsentry/sentry/.venv` (gitignored but missing locally). AGENTS.md describes this setup. * 🟡 (19:42) prek ruff-format auto-reformatted 1 file in getsentry repo. Initial prek run failed, second run after reformat exit code 0. * 🟡 (19:42) Ruff reformatted imports in `tests/getsentry/receivers/test_orbital.py`: moved `MagicMock, patch` from `unittest.mock` to a new dedicated `from unittest.mock import MagicMock, patch` line, alongside `from unittest import mock`. * 🟡 (19:42) ruff format changed 3 files: `getsentry/conf/settings/cellsilo.py` (6 lines), `getsentry/receivers/orbital.py` (45 lines), `tests/getsentry/receivers/test_orbital.py` (48 lines) — 60 insertions(+), 39 deletions(-) * 🟡 (19:43) Local pytest run failed: `ModuleNotFoundError: No module named 'sentry_sdk.traces'`. Installed sentry-sdk was 2.47.0, but pyproject.toml requires `sentry-sdk[http2]==2.66.1`. * 🟡 (19:43) Files in sentry repo importing `from sentry_sdk.traces import StreamedSpan`: `src/sentry/hybridcloud/models/outbox.py`, `src/sentry/issue_detection/performance_detection.py`, `src/sentry/issues/occurrence_consumer.py`, `src/sentry/issues/status_change_consumer.py`, `src/sentry/monitors/consumers/incident_occurrences_consumer.py` * 🟡 (19:43) Assistant upgraded sentry-sdk 2.47.0 → 2.66.1 in `/home/byk/Code/getsentry/sentry/.venv/` via pip install. * 🟡 (19:44) After sentry-sdk upgrade, pytest still failed: `ImportError: cannot import name 'FutureTrackingProducer' from 'arroyo.backends.kafka'`. arroyo package not installed in venv (`WARNING: Package(s) not found: arroyo`). * 🟡 (19:44) sentry pyproject.toml expects `sentry-arroyo>=2.42.0` but it's missing from local venv. The venv is heavily stale; cannot run tests locally. * 🟡 (19:44) mypy direct run also broken: `pyproject.toml:1: error: Error importing plugin "mypy_django_plugin.main": No module named 'mypy_django_plugin'`. mypy_django_plugin not installed. * 🟡 (19:44) Decision: skip local test execution; trust CI. Reasoning: (1) lint/format pass locally, (2) CI was running tests against previous version successfully, (3) mypy errors that were CI-failing are fixed. * 🔴 (19:45) User stated (HIGH PRIORITY): In non-US cells `ORBITAL_UDP_SERVER` is unset, so `notify_orbital` is bound to a noop at module load and emits no per-event metrics. (Source: test docstring `test_notify_orbital_is_noop_when_udp_socket_unset`) * 🟡 (19:45) Final orbital.py (103 lines) structure: imports, module-load `udp_socket`/`udp_addr` init guarded by `if ORBITAL_UDP_SERVER:` with try/except emitting `outcome=no_socket` metric on failure, `_ip_from_event(data: Any) -> str | None`, `_notify_orbital(ip: Any, data: Any = None, **kwargs: Any) -> None` (now prefixed with underscore), conditional `notify_orbital = _notify_orbital` if `udp_socket is not None` else noop `def notify_orbital(*args: Any, **kwargs: Any) -> None: pass`, then `event_accepted.connect(notify_orbital, weak=False)`. * 🟡 (19:45) Code uses `# type: ignore[union-attr]` on `udp_socket.sendto(...)` call because mypy sees `udp_socket`/`udp_addr` could be None even though `_notify_orbital` only binds when `udp_socket is not None`. * 🟡 (19:45) cellsilo.py change: `ORBITAL_UDP_SERVER` default for US cell changed from `orbital-udp.default.svc.cluster.local:5556` to `orbital-udp.default.svc.cluster.local.:5556` (added trailing dot for FQDN). Comment notes: "trailing dot makes the name FQDN so pod-side `ndots:5` doesn't walk search domains on every sendto (same pattern as twemproxy-…svc.cluster.local.)". Reason: old hardcoded `10.2.0.43` (since 2019) no longer reaches all orbital pods reliably. * 🟡 (19:45) For non-US cells: `ORBITAL_UDP_SERVER = env("ORBITAL_UDP_SERVER") or None` (unchanged). defaults.py sets `ORBITAL_UDP_SERVER = ""`. * 🟡 (19:45) Test `test_notify_orbital_is_noop_when_udp_socket_unset` uses skipTest pattern: if `orbital.udp_socket is not
