[issue1735418] file.read() truncating strings under Windows

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

It's a bug in the program's logic. The program assumes that the file
pointer will have advanced by the same number of bytes as were returned
by read(), but it is false when opened in text mode ('r') since text
mode under Windows will convert Windows newlines ('\r\n') into C
newlines ('\n').

Also, please note this is a feature of Windows itself, *not* of Python.
That's why you don't see it happening on e.g. Mac OS X.
And that's why the fix, short of changing the program's logic, is to
open in binary mode ('rb').
