First class windows support

[djs55]

I need to make a datakit server which

• has logging customised for Windows (probably though a custom log reporter)
• listens on a named pipe
• listens on Hyper-V sockets
• is built on Windows in CI (e.g. on Appveyor)

What do you think is the best approach?

I can have a look if you want. I'll start by adding an appveyor file.

How do you listen for Hyper-V sockets? Can you listen on named pipes with the Unix library?

[djs55]

That would be awesome, thanks!

@yomimono and I are investigating named pipes. Normal OCaml doesn't support them, although ocamlnet does. I've started hacking on [djs55/ocaml-namedpipe].

I think Hyper-V sockets will be similar -- probably once we've got named pipes then adding Hyper-V sockets will be ok.

BTW I've got most of the code in piñata building on Windows with camlp4 -- in some cases I back ported windows fixes to before the ppx rewrite. Does datakit prefer camlp4 or ppx?

datakit uses cppo for optional compilation, but no other pre-processor stuff.

I've also compiled a version of datakit on Windows (it was 0.2.0 I think). I'll check that it still compiles and allow ways to do optionally compile more stuff in.

Do you know which logging framework do you want to use on Windows? The current default logger just uses stdout.

[djs55]

Actually stdout will probably work ok for now.

Closing this as datakit works now well on windows.
