A segmentation fault occurred when I try to execute following script:
import datetime
import msgpack
useful_dict = {
"id": 1,
"nickname": "foo",
"created": datetime.datetime.now(),
"updated": datetime.datetime.now(),
}
def decode_datetime(obj):
if b'__datetime__' in obj:
obj = datetime.datetime.strptime("%Y%m%dT%H:%M:%S.%f")
return obj
def encode_datetime(obj):
if isinstance(obj, datetime.datetime):
return {'__datetime__': True, 'as_str': obj.strftime("%Y%m%dT%H:%M:%S.%f")}
return obj
print("Dict before packing: %s" % str(useful_dict))
packed_dict = msgpack.packb(useful_dict, default=encode_datetime)
this_dict_again = msgpack.unpackb(packed_dict, object_hook=decode_datetime)
print("Dict after packing/unpacking: %s" % str(this_dict_again))python test_default.py
Dict before packing: {'updated': datetime.datetime(2012, 10, 12, 10, 47, 34, 405448), 'nickname': 'foo', 'id': 1, 'created': datetime.datetime(2012, 10, 12, 10, 47, 34, 405413)}
[1] 10601 segmentation fault (core dumped) python test_default.pyAfter short investigation using gdb and looking to the source code the reason became clear.
It happens because of insufficient error checking during unpacking process. A problem occurred when some user data structure packed into dictionary.
I've solved the problem in my forked repo and will try to create a pull request.
