In gh-72793: C implementation of parts of copy.deepcopy by eendebakpt · Pull Request #91610 · python/cpython · GitHub part of the python
deepcopy implementation is replaced with C code to improve performance. The PR passes tests and performance is good, but the windows build is failing.
The C code lives in
Modules/_copy.c and I added the new
_copy module to
Modules/Setup.stdlib.in. That was sufficient for the linux build. What more should be done for the windows build?
