           Summary: rpcrt4: NdrClientInitializeNew() does not wait for
                    server connection
           Product: Wine

Application log (WINEDEBUG=+timestamp,+pid,+tid,+seh,+rpc,+file,+sync)

I'm debugging a crash of the RekordboxAgent application. The problem is that
it's terminated by the RPC_S_SERVER_UNAVAILABLE exception.

I noticed that the client connection for the endpoint .\pipe\wine_plugplay (see
NdrClientInitializeNew() API call on line 11168) had been triggered before the
server started listening (see NdrServerInitializeNew() API call on line 13286).

Since the application works well under Windows 10/11, I believe it's a wine
implementation related problem. 
To me it seems like the client connection should wait until the server becomes
available. I made a small patch to test this theory (see rpcrt4.patch). Now I
can see in the logs that the WaitNamedPipeW API is called on line 11189, but
looks like does not have the desired effect as rpcrt4_conn_open_pipe connection
failed appears immediately on line 11194.

Any help regarding that would be appreciated.

Call to

NtFsControlFile( pipe_dev, NULL, NULL, NULL, &iosb, FSCTL_PIPE_WAIT,
  pipe_wait, wait_size, NULL, 0 );

fails on the wineserver side with OBJECT_NAME_NOT_FOUND error (see line 56670
in  the log).

That code was added intentionally, though. It might be incorrect, but it needs
tests to prove it.
