Trying to bson_append a binary value with NULL data asserts.
bson_t ex = BSON_INITIALIZER; /* this asserts */ bson_append_binary (&ex, "a", 1, BSON_SUBTYPE_BINARY, NULL /* data */, 0);
The assertion occurs here.
I think an empty binary value should be valid. From bsonspec.org:
binary ::= int32 subtype (byte*)
Additionally, it seems we can decode JSON with an empty binary value:
bson_t ex = BSON_INITIALIZER; #define JSON(s) #s char* json = JSON({"a": {"$binary": {"base64": "", "subType": "0"}}}); bson_init_from_json (&ex, json, strlen(json), NULL);
But we can get UBSAN errors when copying a bson_value_t of an empty binary value here:
memcpy (dst->value.v_binary.data,
src->value.v_binary.data,
dst->value.v_binary.data_len);
