Thanks for the quick fix! I'm the reporter of #4532. I tested this branch independently with a mock-transport harness and found one remaining gap.
Spans ended while the app still holds the stream (async, openai 3.22.1):
Reproduction: import asyncio, json, httpx, openai
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import SimpleSpanProcessor
from opentelemetry.sdk.trace.export.in_memory_span_exporter import InMemorySpanExporter
from opentelemetry.instrumentation.openai import OpenAIInstrumentor
def sse():
def c(d, f): return {"id": "c1", "object": "chat.completion.chunk", "created": 0, "model": "m",
"choices": [{"index": 0, "delta": d, "finish_reason": f}]}
ev = "".join(f"data: {json.dumps(c({'content': p}, None))}\n\n" for p in ["Hel", "lo", "!"])
return (ev + f"data: {json.dumps(c({}, 'stop'))}\n\ndata: [DONE]\n\n").encode()
exporter = InMemorySpanExporter()
provider = TracerProvider(); provider.add_span_processor(SimpleSpanProcessor(exporter))
OpenAIInstrumentor().instrument(tracer_provider=provider)
async def main():
client = openai.AsyncOpenAI(api_key="x", base_url="http://mock/v1", http_client=httpx.AsyncClient(
transport=httpx.MockTransport(lambda r: httpx.Response(
200, headers={"content-type": "text/event-stream"}, content=sse()))))
s = await client.chat.completions.create(
model="m", messages=[{"role": "user", "content": "hi"}], stream=True)
await s.__aiter__().__anext__()
await s.aclose()
print("spans ended after aclose():", len(exporter.get_finished_spans())) # expected 1, actual 0
asyncio.run(main())Suggested fix: also define Environment: this branch, openai 3.22.1, opentelemetry-sdk 1.45.0, Python 3.12. |
OpenAI SDK 3.x added AsyncStream.aclose(); the wrapt proxy defined only close(), so await stream.aclose() delegated straight to the wrapped stream and the LLM span stayed open until GC. Add an async aclose() that runs the idempotent _ensure_cleanup() first, then delegates to the wrapped stream's aclose when present (getattr guard keeps it safe on SDK 2.x). Regression tests: aclose ends the span on an SDK 3.x-shaped stream, and still ends the span when the wrapped stream has no aclose (2.x). Reported-by: armanunix (review thread on traceloop#4534)

A return inside finally would swallow a BaseException (e.g. KeyboardInterrupt) escaping _ensure_cleanup(). Assign the delegated result in finally and return it afterwards instead.

Fixes #4532
Problem
ChatStreamwired span cleanup into__exit__and__del__only, so when an application reads part of a streamed chat completion and then callsstream.close()(sync) orawait stream.close()(async), the LLM span was not ended. It stayed open until the stream object was garbage-collected:Changes
ChatStream.close()now runs the idempotent_ensure_cleanup()(which ends the span and records partial metrics) before delegating to the wrapped stream'sclose(). For an async wrapped stream it returns a coroutine the caller awaits (await stream.close()); sync streams close inline.ChatStream.__aexit__now runs_ensure_cleanup()like the sync__exit__already did (it previously skipped cleanup entirely).packages/opentelemetry-instrumentation-openai/tests/traces/test_chat_stream_close.py: sync close, async close, idempotency, close-after-full-consumption, sync__exit__, async__aexit__.Small, additive, non-breaking: cleanup is idempotent, and underlying
close()errors still propagate to the caller as before.Test evidence
Bug reproduced first with a mock-based script (0 finished spans after
close()in both sync and async cases); passes after the fix (1 finished span each).New tests: 6/6 pass; 4 of the 6 fail on the unpatched code (the other 2 pin pre-existing
__exit__/full-consumption behavior).Existing suite:
test_semconv_compliance.py(34 tests, exercisesChatStreampaths) all pass with the change;ruff checkclean on both touched files. (test_chat.pyVCR tests error identically on the pristine tree in this sandbox — environmental, unrelated.)I have added tests that cover my changes.
