[New-bugs-announce] [issue15393] JSONDecoder.raw_decode breaks on leading whitespace

[Antti Laine]

New submission from Antti Laine <antti.a.laine at iki.fi>:

raw_decode on json.JSONDecoder does not handle leading whitespace. According to RFC 4627, section 2, whitespace can precede an object. With json.loads leading whitespace is handled just fine.

d = json.JSONDecoder()
d.raw_decode(' {}')
ValueError: No JSON object could be decoded

Tested with versions 2.6.7, 2.7.3, 3.1.3 and 3.2.3
