Sorry if I wasn't clear enough, but when I sent UDF support to ML in ~3 years ago, nobody seemed to care and had no feedback since then, so I thought it would never get accepted and then I gave up on trying to improve, cleanup, etc. -- I even started working write support for it but also gave up. It would not make sense to work on it anymore. Right? I would not know to tell you in which branch it should go, but as the driver gives you the ability to access an UDF fs as it's supposed to, then, IMHO, it'd be ready to go either way. > > >Paulo, >Could you help do more evaluation to the code as you said "I *do* know >that the code really needs refactoring, documentation, etc"?

Yep. We should refactor the code, fix coding style issues, improve documetation. Since I was the only one who tested it, it definitely needs a little more testing. With you help, we definitely can resolve all those TODO items. Thanks!
