test(fastapi): skip flaky websocket subprocess test on 3.19 by christophe-papazian · Pull Request #18982 · DataDog/dd-trace-py

christophe-papazian · 2026-07-10T16:15:49Z

Why

The fastapi websocket subprocess tests are the only tests consistently failing on the 3.19 release pipeline (contrib/fastapi 1/4):

test_traced_websocket
test_websocket_only_sends
test_websocket_tracing_sampling_not_inherited
test_websocket_tracing_not_separate_traces

Each runs in a subprocess and asserts the child's STDERR is empty, but Python's asyncio event loop emits a benign teardown warning at interpreter shutdown:

Exception ignored in: <function BaseEventLoop.__del__ ...>
ValueError: Invalid file descriptor: -1

which pollutes STDERR and fails the assertion deterministically.

This is not a tracer bug — the traceback is pure CPython asyncio/selectors (no ddtrace frames) and Python itself ignores the exception (process exits 0). main already resolves it by running these tests in-process. Rather than backport that larger refactor to a release branch, we skip them on 3.19.

The fastapi websocket subprocess tests (test_traced_websocket, test_websocket_only_sends, test_websocket_tracing_sampling_not_inherited, test_websocket_tracing_not_separate_traces) assert the child process emits no STDERR, but a benign asyncio event-loop teardown warning (BaseEventLoop.__del__ ... 'Invalid file descriptor: -1') pollutes STDERR and fails them deterministically on the release pipeline. It is not a tracer bug (the traceback is pure CPython asyncio, no ddtrace frames), and main already resolves it by running these in-process. Skip them on 3.19.
