Segmentation fault with custom TypeTraverserVisitor #8360
Description
I'm trying to copy methods from one class into the other, need to add some imports to other class' module.
https://github.com/django/django/blob/b9cf764be62e77b4777b3a75ec256f6209a57671/django/db/models/manager.py#L101
I'd like to use custom TypeTraverserVisitor for that
signature_node: FuncDef
def import_symbol_from_source(name: str) -> None:
if name in source_symbols['__builtins__'].node.names:
return
sym = source_symbols[name].copy()
self.semanal_api.add_imported_symbol(name, sym, context=self.semanal_api.cur_mod_node)
class UnimportedTypesVisitor(TypeTraverserVisitor):
def visit_instance(self, t: Instance) -> None:
super().visit_instance(t)
if isinstance(t.type, FakeInfo):
return
type_name = t.type.name
sym = currently_imported_symbols.get(type_name)
if sym is None:
import_symbol_from_source(type_name)
signature_node.type.accept(UnimportedTypesVisitor())
Compiled version of mypy segfaults for me, when I'm trying to use code like this. The plain Python version runs just fine.
