This is the minimum required code to showcase this example. I can show more if it's still needed, let me know. It's possibly related to how something like:
@dataclass(eq=False, repr=False)
class AnyValue(betterproto.Message):
string_value: str = betterproto.string_field(1, group="value")
bool_value: bool = betterproto.bool_field(2, group="value")
int_value: int = betterproto.int64_field(3, group="value")
double_value: float = betterproto.double_field(4, group="value")
array_value: "ArrayValue" = betterproto.message_field(5, group="value")
kvlist_value: "KeyValueList" = betterproto.message_field(6, group="value")
bytes_value: bytes = betterproto.bytes_field(7, group="value")This definitely works for the intended use case. You may have not instantiated the Message
Is there a unit test that shows this functionality is working?

from dataclasses import dataclass
from typing import List
import betterproto
@dataclass(eq=False, repr=False)
class AnyValue(betterproto.Message):
string_value: str = betterproto.string_field(1, group="value")
bool_value: bool = betterproto.bool_field(2, group="value")
int_value: int = betterproto.int64_field(3, group="value")
double_value: float = betterproto.double_field(4, group="value")
bytes_value: bytes = betterproto.bytes_field(7, group="value")
@dataclass(eq=False, repr=False)
class KeyValue(betterproto.Message):
key: str = betterproto.string_field(1)
value: "AnyValue" = betterproto.message_field(2)
@dataclass(eq=False, repr=False)
class ObjectWrapper(betterproto.Message):
content: bytes = betterproto.bytes_field(1)
@dataclass(eq=False, repr=False)
class InnerObject(betterproto.Message):
attributes: List[KeyValue] = betterproto.message_field(1)
key_value = KeyValue(key="my_key_value", value=1000000000)
inner_object = InnerObject(attributes=[key_value])
# This fails
my_wrapper = ObjectWrapper(content=bytes(inner_object))
print(my_wrapper)
Summary
Getting the bytes of an int64_field is leading to infinite recursion
Reproduction Steps
Script to reproduce:
The area of issue is likely in this part of the code: https://github.com/danielgtaylor/python-betterproto/blob/master/src/betterproto/__init__.py#L470-L498
Expected Results
The bytes to represent the number are returned.
Actual Results
Using the script, after running the second
print(bytes(int64_field))infinite recursion seems to occur. It will continue to print out the following string forever:System Information
Checklist
pip install -U --pre betterproto, if possible.
