New submission from Vincent Michel <vxgmic...@gmail.com>:
I'm not sure whether it is intended or not, but I noticed a change in the behavior of `StreamReader` between version 3.7 and 3.8. Basically, reading some received data from a closed TCP stream using `StreamReader.read` might hang forever, under certain conditions. I'm not sure what those conditions are but I managed to reproduce the issue consistently with the following workflow: - server writes some data - client reads a part of the data - client closes the writer - server closes the writer - client tries to read the remaining data The test attached implements the behavior. It fails on 3.8 but passes on 3.7 ---------- components: asyncio files: stuck_on_py38.py messages: 328430 nosy: asvetlov, vxgmichel, yselivanov priority: normal severity: normal status: open title: Reading received data from a closed TCP stream using `StreamReader.read` might hang forever versions: Python 3.8 Added file: https://bugs.python.org/file47891/stuck_on_py38.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35065> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
