In twisted.internet.abstract.FileDescriptor.loseConnection, the
loseConnection method
is defined like:
def loseConnection(self,
_connDone=failure.Failure(main.CONNECTION_DONE)):
while in twisted.internet._newtls.ConnectionMixin , we have:
def loseConnection(self):
If I run *tox -e mypy* in trunk, mypy complains with this:
src/twisted/internet/tcp.py:204:1: error: Definition of
"loseConnection" in base class "ConnectionMixin" is incompatible with
definition in base class "FileDescriptor" [misc]
src/twisted/internet/tcp.py:527:1: error: Definition of

src/twisted/internet/unix.py:431:1: error: Definition of

definition in base class "FileDescriptor" [misc]
Do the signatures of loseConnection need to match in order for this to
be a valid subclass?
Is there any way to fix the code so that the mypy error goes away, or
do we need to add a comment to turn off the mypy error here?
