New submission from STINNER Victor: The following code copies data, whereas the copy can be avoided using a memory view:
chunk = self._input[self._input_offset:self._input_offset + _PIPE_BUF] self._input_offset += os.write(key.fd, chunk) It should be replaced with: input_view = memoryview(self._input) ... chunk = input_view[self._input_offset:self._input_offset + _PIPE_BUF] self._input_offset += os.write(key.fd, chunk) This issue is a reminder for one of my comment of issue #18923. ---------- messages: 202240 nosy: haypo, neologix priority: normal severity: normal status: open title: subprocess.communicate() should use a memoryview versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19506> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
