I have a lisp xml-rpc server. When I launch it from a repl in a terminal, the server responds to the client's requests but when this server is launched from the sly repl in Emacs, the client is stuck waiting.

I don't understand why this happens...

EDIT (yes it wasn't clear): I use s-xml-rpc, https://s-xml-rpc.common-lisp.dev/

In the sly-mrepl for sbcl, if I define a function like this :

(defun s-xml-rpc-exports::|lisp.GCD| (m n)
  (gcd m n))

and then I start the server in the sly-mrepl:

  (setq *xml-server* (s-xml-rpc:start-xml-rpc-server :port 6665 ))

from a client written in python :

import xmlrpclib

print(xmlrpclib.ServerProxy("http://localhost:6665/RPC2").lisp.GCD(12155, 130130))

the client remains blocked without a response from the server.

but

but if I do the same thing but from a sbcl repl launched from the terminal, the server answers and the client displays 715

    Hi VaK. You will get better answers if you include details. Which CL? On which platform? Which XML-RPC server? Which CLI client, and what does its output look like? Which version of sly? Is there *any* output? Which version of Emacs? On which platform? Any or all of these *could* be decisive. – Phil Hudson Apr 28 '22 at 08:22
  • Can you see the server with `netstat -plan` or similar? Is there any way to turn on logging by the server to see what it's doing? – NickD Apr 28 '22 at 19:28
  • yes i can see the server with netstat – VaK Apr 28 '22 at 20:24
