Related to #618.
To support Python 3.13, changes are required in the codebase of the
_coclass_meta
,_cominterface_meta
, and_make_safearray_type
.This is due to changes in the implementation of
ctypes
starting from Python 3.13, which introduced breaking changes to metaclass initialization.I posted about this in python/cpython#124520 and arrived at this implementation after receiving advice from the
ctypes
maintainer.Please see also https://docs.python.org/3.13/whatsnew/3.13.html#ctypes.
I would like to hear from the community and other maintainers whether the codebases are reasonable and the comments will be helpful for future readers.
Any feedback is welcome.
If there are no objections, I plan to merge this after October 21st and release it as
comtypes==1.4.8
.
