New submission from Thomas Krennwallner <t...@postsubmeta.net>:
The `inspect` module does not contain functions for determining the current state of asynchronous generators. That is, there is no introspection API for asynchronous generators that match the API for generators and coroutines: https://docs.python.org/3.8/library/inspect.html#current-state-of-generators-and-coroutines. I propose to add `inspect.getasyncgenstate` and `inspect.getasyncgenlocals` (following `inspect.isasyncgenfunction` and `inspect.isasyncgen`). % ./python Python 3.8.0a0 (heads/fix-issue-getasyncgenstate:a24deae1e2, Jan 17 2019, 11:44:45) [GCC 6.3.0 20170516] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import inspect >>> async def agen(): ... x = 1 ... yield x ... x += 1 ... yield x ... >>> ag = agen() >>> inspect.getasyncgenstate(ag) 'AGEN_CREATED' >>> inspect.getasyncgenlocals(ag) {} >>> ag.__anext__().__next__() Traceback (most recent call last): File "<stdin>", line 1, in <module> StopIteration: 1 >>> inspect.getasyncgenstate(ag) 'AGEN_SUSPENDED' >>> inspect.getasyncgenlocals(ag) {'x': 1} >>> ag.__anext__().__next__() Traceback (most recent call last): File "<stdin>", line 1, in <module> StopIteration: 2 >>> inspect.getasyncgenstate(ag) 'AGEN_SUSPENDED' >>> inspect.getasyncgenlocals(ag) {'x': 2} >>> ag.aclose().send(None) Traceback (most recent call last): File "<stdin>", line 1, in <module> StopIteration >>> inspect.getasyncgenstate(ag) 'AGEN_CLOSED' >>> inspect.getasyncgenlocals(ag) {} ---------- components: Library (Lib) files: 0001-inspect-add-introspection-API-for-asynchronous-gener.patch keywords: patch messages: 333861 nosy: tkren priority: normal severity: normal status: open title: inspect module does not implement introspection API for asynchronous generators type: enhancement versions: Python 3.8 Added file: https://bugs.python.org/file48066/0001-inspect-add-introspection-API-for-asynchronous-gener.patch _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35759> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
