rpc status: fix for Win32 #8806

nojb · 2023-09-30T22:19:11Z

Beginning of a fix for #8799, but not complete because dune rpc status does not seem to be fully working:

(no data is reported for the connected client)

After further testing, it seems to be working:

@Alizter, can you give it a try on your side to confirm? Thanks!

Works great, thanks!

cc @emillon any chance we can get this backported for 3.9-3.11? Or at least add it to a list in case another point release is decided.

otherlibs/dune-rpc/private/where.ml

-        | Error e -> Error e
-        | Ok contents ->
-          (match of_string contents with
+      (match default ~build_dir () with


I don't know what the issue is yet, but this fix doesn't seem right to me. Previously, the code would look at the socket inside the build directory to connect, and now it's just assuming the address is the default address.

Nothing has changed here for Unix systems: default ~build_dir () still returns the socket inside the build directory:

dune/otherlibs/dune-rpc/private/where.ml

Lines 130 to 134 in 071cb47

let default ?(win32 = win32) ~build_dir () =

if win32

then `Ip (`Host (Unix.string_of_inet_addr Unix.inet_addr_loopback), `Port default_port)

else `Unix (Filename.concat build_dir rpc_socket_relative_to_build_dir)

;;

Okay, but even on Windows, the workflow to connect should be:

Inspect the file _build/.rpc/dune

If it's a socket, connect to it (will never happen on windows)

If it's a normal file, read it and get the connection string from here. On windows, that connection string will have the address we want to connect on.

Oops, you are right. I hadn't grasped the logic behind the client/server split. Now I pushed a commit with the right fix I think.

src/dune_rpc_client/where.ml

-  | `Ip (`Host host, `Port port) -> sprintf "%s:%d" host port
-;;
+let to_string t = Dune_rpc_private.Where.to_string t


Use the right "dbus" format so that it can be parsed back in

dune/otherlibs/dune-rpc/private/where.ml

Lines 154 to 162 in 071cb47

let of_file f =

let+ contents = IO.read_file f in

match contents with

| Error e -> Error e

| Ok contents ->

(match of_string contents with

| Error e -> Error e

| Ok s -> Ok (Some s))

+- Fix `dune rpc status` on Windows (#8806, fixes #8799, @nojb)


This fixes a little more than status. It should fix all dune rpc commands in fact.

Looks like monitor too.

Thanks for the review. I amended the Changes entry.

Works great, thanks!

Sure. To be clear, this is a regression introduced in 3.9.0?

I suspect this has never worked on Windows, until this PR.

emillon · 2023-10-02T07:08:58Z

OK. Note a huge rush then. I'll backport that to 3.11.1.
