New submission from Amaury Forgeot d'Arc <[email protected]>:
The script below shows that the error handler is always called with the same
error object. The 'start', 'end', and 'reason' properties are correctly
updated, but the 'args' is always the same and holds the values used for the
first call.
It's a bit weird that error.args[2] is not equal to error.start, for example.
All versions are affected: 2.7, 3.2, 3.3.
And by the way, I could not find where these are attributes documented.
def custom_handler(error):
print(error.args,
(error.start, error.end, error.reason))
return b'?'.decode(), error.end
import codecs
codecs.register_error('custom', custom_handler)
b'\x80\xd0'.decode('utf-8', 'custom')
