fix(openai): async pagination for OpenAI list methods #14911

PROFeNoM · 2025-10-16T09:49:20Z

Hey, so this is an attempt to fix #14574 where doing async for model in client.models.list() would fail with TypeError: 'async for' requires an object with __aiter__ method, got coroutine.

The Problem

Methods like AsyncModels.list() and AsyncFiles.list() don't actually return coroutines - they return AsyncPaginator objects that you can either:

await to get the first page (what existing code does)
Use with async for to iterate through all items (what was broken)

But our wrapper in _patched_endpoint_async was converting everything into coroutines, which broke the async for use case.

What I Tried

First attempt was using inspect.iscoroutinefunction() to detect which methods are actually async vs just returning async objects. That got messy fast because checking unbound methods from classes didn't work reliably.

Then I tried just using the sync wrapper for list methods:

if method_name == "list":
    wrap(openai, async_method, _patched_endpoint(openai, endpoint_hook))

This looked promising - the pagination tests passed! But it broke test_model_alist and test_file_alist because those tests do await client.models.list() and expect full tracing with response metadata like openai.response.count. Using the sync wrapper meant we lost all that when the paginator was awaited.

Also tried returning the paginator directly without any wrapping, but that meant we lost tracing entirely when someone did async for. Not acceptable.

A Solution

Created a _TracedAsyncPaginator wrapper class that implements both __aiter__ and __await__. This way:

When you do await client.models.list() -> calls __await__, traces properly, returns first page (existing behavior preserved)
When you do async for model in client.models.list() -> calls __aiter__, traces on first iteration, yields items (fixes the bug)

The wrapper is ~50 lines but it's the minimal solution that preserves 100% backward compatibility while fixing the breaking bug. Had to use finally blocks to ensure traces complete even if iteration stops early.

Testing

Added two new pagination tests (test_model_list_pagination and test_model_alist_pagination) that specifically test the async for pattern.

Hey, so this is an attempt to fix #14574 where doing `async for model in client.models.list()` would fail with `TypeError: 'async for' requires an object with __aiter__ method, got coroutine`. ### The Problem Methods like `AsyncModels.list()` and `AsyncFiles.list()` don't actually return coroutines - they return `AsyncPaginator` objects that you can either: - `await` to get the first page (what existing code does) - Use with `async for` to iterate through all items (what was broken) But our wrapper in `_patched_endpoint_async` was converting everything into coroutines, which broke the `async for` use case. ### What I Tried First attempt was using `inspect.iscoroutinefunction()` to detect which methods are actually async vs just returning async objects. That got messy fast because checking unbound methods from classes didn't work reliably. Then I tried just using the sync wrapper for list methods: ```python if method_name == "list": wrap(openai, async_method, _patched_endpoint(openai, endpoint_hook)) ``` This looked promising - the pagination tests passed! But it broke `test_model_alist` and `test_file_alist` because those tests do `await client.models.list()` and expect full tracing with response metadata like `openai.response.count`. Using the sync wrapper meant we lost all that when the paginator was awaited. Also tried returning the paginator directly without any wrapping, but that meant we lost tracing entirely when someone did `async for`. Not acceptable. ### A Solution Created a `_TracedAsyncPaginator` wrapper class that implements both `__aiter__` and `__await__`. This way: - When you do `await client.models.list()` -> calls `__await__`, traces properly, returns first page (existing behavior preserved) - When you do `async for model in client.models.list()` -> calls `__aiter__`, traces on first iteration, yields items (fixes the bug) The wrapper is ~50 lines but it's the minimal solution that preserves 100% backward compatibility while fixing the breaking bug. Had to use `finally` blocks to ensure traces complete even if iteration stops early. ### Testing Added two new pagination tests (`test_model_list_pagination` and `test_model_alist_pagination`) that specifically test the `async for` pattern. (cherry picked from commit 52929aa)
