Hello,
(progn
(require 'server)
(setq server-use-tcp t)
(server-start))
generates an error:
Debugger entered--Lisp error: (error "localhost/0 nodename nor servname provided, or not known")
make-network-process(:name "server" :server t :noquery t :sentinel server-sentinel :filter server-process-filter :coding raw-text-unix :family nil :service t :host local :plist (:authenticated nil))
apply(make-network-process :name "server" :server t :noquery t :sentinel server-sentinel :filter server-process-filter :coding raw-text-unix (:family nil :service t :host local :plist (:authenticated nil)))
server-start()
(progn (require (quote server)) (setq server-use-tcp t) (server-start))
eval((progn (require (quote server)) (setq server-use-tcp t) (server-start)))
eval-last-sexp-1(nil)
eval-last-sexp(nil)
call-interactively(eval-last-sexp nil nil)
Any idea how to fix this?
Tested with GNU Emacs 23.2.3 (x86_64-apple-darwin10.3.0, X toolkit)
of 2010-05-23 on Victoria.local.

That is not server.el-specific, is it? I mean, you're getting an error
on calling make-network-process to create a TCP server. Do you get an
error from
(make-network-process :name "server" :server t :family nil :service t
:host 'local)

Yeah make-network-process is the problem; it is in C and I don't know
how to fix it.
I have used the following in server-start as workaround:
(make-network-process :name "server" :server t :family 'ipv4 :service t)
BTW, with the server running over TCP, I can eval sexp in a shell script
from another machine and inform emacs what's going on there. That is
very useful when my code and build are in two different machines.
Kind regards,
Leo

If ":family 'ipv4" works and ":family nil" does not, that surely means
that Emacs is chosing ipv6. Does server.el work with the attached
patch?
I don't know whether that means that your system is set up only for
ipv6, or that it has both ipv6 and ipv4 and make-network-process is
selecting ipv6 for `localhost'. In any case, server.el / emacsclient.c
are not adapted to ipv6, so forcing ipv4 seems right for the moment
being.

There was one more difference, which was that your suggestion included ":host 'local" and his workaround did not.
Using ":host 'local" causes the C code to look up the name "localhost", which may or may not map to IPv4 and/or IPv6 addresses. (Almost always an IPv4 address of 127.0.0.1; sometimes IPv6 also, and I've occasionally seen it mapped to the local ethernet interface's IPv4 address.) Not specifying the host at all causes a wildcard address to be used, which would be reachable from other hosts, whereas 127.0.0.1 generally is not. (Actually, in the version I'm looking at, which isn't quite current, it causes INADDR_ANY to be used, which looks like a bug if the address family is not specifically given as AF_INET. I'll try to look at that a little closer if I get some time next weekend.)

[Ah, the wonders of TCP.]
I think you're right, because in Leo's examples it works when he
specifically sets "127.0.0.1", so it's clear that Emacs isn't
selecting that address with "localhost" or 'local. I suppose the Right
Thing to do for server.el is to force it to use "127.0.0.1" instead of
'local for the :host argument.

I meant that server.el should stick to IPv4 and make sure it does so,
not that it was the fix for your problem.
If you ping localhost and it reaches 127.0.0.1, but
(make-network-proces ... :host 'local) does not use that address, it
is obvious there's a bug somewhere...

Still a problem, isn't it?

gethostbyname works quite different from getaddrinfo.

Still a problem that (make-network-process ... :host 'local) fails.
Something's obviously not right.

I suspect there is a bug in getaddrinfo on Mac OS X 10.6.4. At least,
the behavior of the following program is incompatible with that on Mac
OS X 10.5.8.
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
main ()
{
struct addrinfo hints, *res;
char *servnames[] = {"0", "1", NULL};
int error, i;
memset (&hints, 0, sizeof (hints));
hints.ai_family = PF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;
for (i = 0; i < sizeof (servnames) / sizeof (servnames[0]); i++)
{
if (servnames[i])
printf ("servname = \"%s\":\n", servnames[i]);
else
printf ("servname = (null):\n");
error = getaddrinfo ("localhost", servnames[i], &hints, &res);
if (error != 0)
puts (gai_strerror (error));
else
{
struct addrinfo *r;
for (r = res; r; r = r->ai_next)
{
printf ("family = %d, socktype = %d, protocol = %d\n",
r->ai_family, r->ai_socktype, r->ai_protocol);
}
freeaddrinfo (res);
}
puts ("");
}
}

Actually, one can find a major rewrite in getaddrinfo's
implementation. (Libinfo in

That would make sense if emacsclient.c only supports ipv4. Not being
up-to-speed on ipv6, I do not know whether that's the case.

We should rather do that in the C code of make-network-process, where
instead of "localhost" we might prefer using "127.0.0.1".

It is right now, at least because there are a few hardcoded 127.0.0.1.

Wouldn't that run counter to adapting to IPv6?

Could be, but if the workaround is needed for server.el, I can't see why
it would not be needed for other (IPv4) uses of make-network-process.

You're right, but at the moment we haven't received any other
complain, and it's equally possible that changing it will break
someone's code that works right now.
But, all in all, I agree that if `localhost' can be interpreted as
variably as Ken has pointed out, we shouldn't use it.

For Emacs-24's code, it's OK because we have a fair bit of time to test it.

Could you make the corresponding change in `trunk'?

That is another bug. I'm closing this one.
I suggest either commiting your fix, if appropriate, or filing a new
