It's not documented what that does, but I assume it picks a random free port? In that case, is there a way to find out what it picked?

Yeah I had the feeling that's what it does but couldn't find anything explicitly saying so. I guess that means this would also be satisfied by a getPort sort of...

I think it's not just aesthetics, because in the recommended pattern you still have that extra 5, which can go wrong in two ways: one is updated in one place...

Sorry about the delay, got distracted for a while. Yes I was aware of the `--derivation` behaviour, in this case I was wanting to take advantage of the quirk by...

Yeah there errors I'm seeing are a bit different, not sure if they're the same underlying problem. It may be hard to reproduce without building a lot of things in...

BTW, I can now pretty easily reproduce this. Even after implementing a retry, it'll fail so much that on every single build it exceeds the 3 try maximum every time....

Wow, this is good news. Unfortunately my old code to use ca-derivations has surely gotten quite obsolete, so it'll take some time to bring it back to test this. I'll...

@kittywitch very interesting, can you say how you discovered this workaround? Is nix intentionally using ControlMaster for latency reasons, or accidentally picking it up from the ambient ssh config? Also,...

It's that a missing argument on the toplevel function `confusing` instead gets (apparently) pinned on `do_thing`. The ideal thing would be for it to say the signature and declaration don't...

Yes, I agree the error "Couldn't match expected type `() -> Either String Int with actual type Either String Int` is reasonable, and the misleading part is where it points....
