Re: mailq on solaris 8

[Trent MacDougall <trent@infointeractive.com>]

Matti,

I found where the problem is, but I don't quite understand it. Solaris 8 has
getaddrinfo...I did some debugging and found that gettaddrinfo was returning
a 3 (EAI_BADFLAGS).  I then found that mailq.c was including:

#if     defined(HAVE_SOCKET) && (defined(HAVE_RESOLVER) || defined(HAVE_YP))
#include <netdb.h>
#ifndef EAI_AGAIN
# include "netdb6.h"
#endif
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <fcntl.h>
#include <sys/file.h>
#endif  /* HAVE_SOCKET */

netdb.h defines:

#define AI_CANONNAME    0x0010  /* return canonical version of host */

And then netdb6.h defines:

#ifndef AI_CANONNAME
#define AI_CANONNAME   2       /* Request for canonical name.  */
#endif

I then took the define of AI_CANONNAME from netdb.h and put in in the
mailq.c code right before you initialize the req and ai structures around
line 315, recompiled and:

mail# mailq -sv
0 entries in router queue: idle
0 messages in transport queue: idle
Transport queue is empty -- or scheduler uses -Q -mode


What do you make of this?
