New submission from STINNER Victor <[EMAIL PROTECTED]>:
_json module of python 3.0 has some bugs.
(a) [_json.c] raise_errmsg() calls json.decoder.errmsg() from Python
module, but this function may fails. If it fails, error should be be
set to NULL. Example:
>>> import _json
>>> _json.scanstring(b"xxx", 1, "xxx")
Erreur de segmentation (core dumped)
=> json.decoder.errmsg() calls linecol() which raise an error on
b"xxx".index("\n").
(b) [_json.c] py_encode_basestring_ascii() calls PyBytes_Check(rval)
but rval can be NULL if ascii_escape_str() or ascii_escape_unicode()
fails. Example:
>>> import _json
>>> _json.encode_basestring_ascii(b"xx\xff")
Erreur de segmentation (core dumped)
(c) [Lib/json/decoder.py] linecol() doesn't support bytes, but it's
called with bytes argument: see point (a). For an example, see point
(a).
