[BUG] deepfreeze modifies the original dict

[kenodegard]

Welcome! You should write in your Bug Report:

OS version (https://www.google.com/search?channel=fs&q=check+os+version&ie=utf-8&oe=utf-8):
macOS 14.3

Python3 version (python3 -V -V):
Python 3.12.2

Steps to reproduce:

1. Create some nested dict and call deepfreeze on it.

Actual result (with the python stack trace if present):

>>> o = {'a': 1, 'nested': {'b': 2}}
>>> d = deepfreeze(o)
>>> d
frozendict.frozendict({'a': 1, 'nested': frozendict.frozendict({'b': 2})})
>>> o
{'a': 1, 'nested': frozendict.frozendict({'b': 2})}

I expected deepfreeze to leave the original object untouched.

Well, that's why is called deepfreeze. If you want to freeze only the main object, do

d = frozendict.frozendict(o)

[kenodegard]

But frozendict will only make the outter most object immutable.

Isn't the goal of deepfreeze to create a recursively immutable object?

I'm not understanding why deepfreeze should have any affect the original data structure.

Can you please provide the expected output?

Sorry for misunderstanding, the patch will be released in v2.4.2
