Argh! This was really annoying! Much time wasted (one naturally thinks that
silly error must be one's own).
But, anyway:
Lines:
244 nitems = (chunk.chunksize - chunk.size_read) / self._sampwidth
464 self._nframes = initlength / (self._nchannels * self._sampwidth)
Need to use Python 3.x "//" integer division.
As a workaround, at least for writing wav-files (I haven't tested reading), one
may just set the number of frames exactly before writing them.
That should also fix any problems with piping (avoiding file pos seek to patch
up header).
Also, the unit test should best be improved to check that updating and
backpatching of number of frames actually works.
PS: It would be nice if someone(TM) could describe here in detail how to
properly report errors like this. Of course I'm not going to do it if it
involves establishing Yet Another Account somewhere. But hopefully it doesn't?
Cheers & hth.,
