Commit Message

build a new tuple for each lookup in copyreg._extension_registry

The previous approach of reusing the same tuple and mutating its
contents, which is impossible in python, stopped working after cpython
3.14, after commit 8614f86b716 (gh-131525: Cache the result of
tuple_hash (#131529), 2025-03-27)

This change modifies _pickle_33.c to build a new tuple for each lookup
, using the same logic that is now in cpython's pickle.c , since cpython
commit 23bdd83053d (Encapsulate cpickle global state in a dedicated
object., 2013-11-27)
