Works just fine for me on 3.7.3 on Ubuntu, reading 4096 bytes. How is it failing for you? Is an exception raised? It does seem faintly dangerous to explicitly use O_DIRECT when you're wrapping it in a buffered reader that doesn't know it has to read in units matching the minimum block size (file system dependent on older kernels, 512 bytes in Linux kernel 2.6+); BufferedIOBase.readinto is explicitly documented to potentially issue multiple read calls (readinto1 guarantees it won't do that at least). ---------- nosy: +josh.r _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38167> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
