Could you try with the attached patch ?
The problem is that subprocess silently replaces bufsize=0, so child.stdout is actually buffered, and when you read just one byte, everything that's available for reading is read into the python's object buffer. Then, select/poll doesn't see the pipe as ready for reading since everything as already been read.
Mixing buffered I/O and select leads to trouble, you're right to pass bufsize=0, but I don't know why subprocess goes out of its way and buffers it anyway:
if bufsize == 0:
bufsize = 1 # Nearly unbuffered (XXX for now) |
