New submission from Sergey Kostyuk: Good day
Maybe I misunderstood something, but I'm failed to fetch any data by calling asyncio.StreamReader.read if `n` is less than zero (or left default). It just hangs in the loop forever (see line number 614 of asyncio/streams.py: https://github.com/python/cpython/blob/3e56ff0/Lib/asyncio/streams.py#L614). If `n` is equal to any positive value - coroutine works as expected and returns if there is any data in socket buffer. Even if available data size is less than `n` bytes. Expected behavior: collect all data from the buffer and return Current behavior: hangs in the loop forever if n < 0 My usage sample: https://git.io/v7nJq ---------- components: asyncio messages: 299332 nosy: Sergey Kostyuk, yselivanov priority: normal severity: normal status: open title: asyncio.StreamReader.read hangs if n<0 type: behavior versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31059> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
