Hello, patool FTBFS depends on Archmage, which is Python 2 only. I'm trying to convert it to Python 3. So far I have the dependency pychm converted: https://copr.fedorainfracloud.org/coprs/eclipseo/pythontests/build/903162/ Here's my Py3 port with 2to3 and minor fixes: https://github.com/eclipseo/archmage/tree/python3_port The problem is it doesn't work as expected: $ archmage -x t.chm Traceback (most recent call last): File "/usr/bin/archmage", line 11, in <module> load_entry_point('archmage==0.3.1', 'console_scripts', 'archmage')() File "/usr/lib/python3.7/site-packages/archmod/cli.py", line 161, in main CHMFile(options.chmfile) or CHMDir(options.chmfile) File "/usr/lib/python3.7/site-packages/archmod/Cached.py", line 34, in __new__ __instance = object.__new__(classtype, *args, **kwargs) TypeError: object.__new__() takes exactly one argument (the type to instantiate) I haven't touched archmod/Cached.py code, and as far as I know the object.__new__() method has not changed from Python 2 to Python 3 so I don't get why it's not working anymore. Can anyone with more Python chops help me? For testing, use the chm from patool available here: https://eclipseo.fedorapeople.org/archmage_test/ Thanks
