Something else occurred since 5 years: the PEP 475 was accepted, it makes Python more reliable when it receives signals. If recv(WAIT_ALL) is interrupted by a signal and returns less bytes, we must call PyErr_CheckSignal(). If the signal handler raises an exception, drop read data and raises the exception. If the signal handler does not raise an exception, we now *must* retry recv(WAIT_ALL) (with a shorter length, to not read too much data). The IncompleteRead exception is still needed if the socket is closed before receiving the requested number of bytes. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1103213> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
