JSON

The libsson function bson_as_json does not properly serialize the extended JSON type Code.

The expected behavior is to output an object with "$code" and "$scope" attributes as demonstrated by json_util from PyMongo

>>> import bson

>>> from bson import json_util

>>> from bson.code import Code

>>> json_util.dumps({"code": Code("function x() { return 1; }")})

'{"code": {"$code": "function x() { return 1; }", "$scope": {}}}'

>>> b = bson.BSON.encode({"code": Code("function x() { return 1; }")})

>>> b

'*\x00\x00\x00\rcode\x00\x1b\x00\x00\x00function x() { return 1; }\x00\x00'

>>> import bjson

>>> bjson.dumps(b)

'{ "code" : "function x() { return 1; }" }'

>>>

bjson.dumps is a thin wrapper around bson_as_json using the Python C API.
