Summary: str.join() intercepts UnicodeDecodeError raised by iterator
Initial Comment:
This is somewhat similar to #905389 which has already been fixed.
If you run the following two lines,
def gen(): raise UnicodeDecodeError
''.join(gen())
then instead of UnicodeDecodeError, you get:
TypeError: function takes exactly 5 arguments (0 given)
I found this bug in Python 2.3.5, 2.4.4 and 2.5.1 on Windows and Linux.
The bug appears exactly for UnicodeDecodeError,
UnicodeEncodeError, UnicodeTranslateError; all other exceptions work as
expected. You can verify this with the following program:
import exceptions
def gen(e): raise e
for e in dir(exceptions):
e = getattr(exceptions, e)
if type(e) != type(Exception):
continue
try:
''.join(gen(e))
except BaseException, f:
e = e.__name__
f = f.__class__.__name__
if e != f:
print e, f
