Handler for the various legacy things that a contextFactory can be.

Exception LegacyContextFactoryWarning You should be using a newer TLS context configuration interface.
Function older Compatibility shim for IOpenSSLContextFactory.getContext-style method to create(Client/Server)Creator.
Function oldest Comptibility shim that does largely the same thing as older but for things that don't even properly implement the old-style interface; check explicitly for the method and try to provide a useful assert if the object is just the wrong type rather than simply using an older API.
Type Alias SingleArgFactory Undocumented
Type Alias SomeConnectionCreator Undocumented
Function _convertToAppropriateFactory Upgrade a connection creator / context-factory-ish object into something with a signature like the most recent interface for building OpenSSL connection objects (i.e. like the methods on IOpenSSLClientConnectionCreator...

Compatibility shim for IOpenSSLContextFactory.getContext-style method to create(Client/Server)Creator.

def _convertToAppropriateFactory(isClient: bool, creator: SomeConnectionCreator) -> SingleArgFactory: (source)

Upgrade a connection creator / context-factory-ish object into something with a signature like the most recent interface for building OpenSSL connection objects (i.e. like the methods on IOpenSSLClientConnectionCreator and IOpenSSLServerConnectionCreator), accounting for all the various interfaces older versions of Twisted used for context configuration.
