There is a real need of non-blocking operation, but I now think that adding a set_blocking() method is not the right solution. First, as said by Charles-Francois: O_NONBLOCK flag has no effect on regular files. Second, there is no portable way to declare a file as "non blocking": as said by Tim, it is complelty different on Windows (I/O Completion ports).
The asyncio module has been merged into Python 3.4: you can now use it to access a file asynchroniously. I don't think that the asyncio is complete for your use case, but if something should done: it is in this module, only in this module, not the API of the io.FileIO class.
asyncio can be used to watch pipes of a subprocess asynchroniously. |
