A call to os.read that used to work on older Linux kernel, doesn't anymore with newer Linux kernel. As a workaroud we can use libc.read (ctypes) instead of os.read. But I feel like os.read should work, as it used to. The code (and comments) can be seen here : http://code.activestate.com/recipes/576375-low-level-inotify-wrapper/ |

Can you please explain what the bug is in Python; that is, what exactly was wrong with os.read? |

This is not a Python bug. Linux is just not accepting "0" as a valid size argument to read(). You don't see this using libc.read because you don't check errno. Just don't call os.read() if size == 0. |

Thanks Benjamin ! I should have known that "Python doesn't break things" :) |
