New submission from ivank <[email protected]>:
This probably only applies to Windows. The redundant 'b' modes still work on
Linux.
These worked on Windows in 2.6.4:
open('test', 'rbb')
open('test', 'wbb')
open('test', 'abb')
and possibly others.
In 2.7a2, they throw ValueErrors like this:
>>> open('test', 'wbb')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: Invalid mode ('wbb')
It would be nice if the old behavior were preserved for backwards
compatibility. Some programs append a 'b' indiscriminately.
