No matter how I modify this following code it does not work with Solaris. Solaris always returns "non-recoverable name resolution failure":
int error;
char port_buf[NI_MAXSERV];
size_socket addrLen = sizeof(vio->remote);
if (getpeername(vio->sd, (struct sockaddr *) (&vio->remote),
&addrLen) != 0)
{
DBUG_PRINT("exit", ("getpeername gave error: %d", socket_errno));
DBUG_RETURN(1);
}
if ((error= getnameinfo((struct sockaddr *)(&vio->remote),
sizeof(struct sockaddr_storage),
buf, buflen,
port_buf, NI_MAXSERV, NI_NUMERICHOST|NI_NUMERICSERV)))
{
WATCHPOINT_STRING(gai_strerror(error));
DBUG_PRINT("exit", ("getnameinfo gave error: %s",
gai_strerror(error)));
DBUG_RETURN(1);
}
Linux, FreeBSD, OSX, AIX, Windows.... all are fine. Except Solaris. For DNS resolution nsswitch.conf lists files, then DNS.
I am completely capable of FUBAR code myself. So some part of me really does believe this is my mistake. When I google for "non-recoverable name resolution failure" and Solaris I get plenty of hits though, so I am skeptical.
Very few open source projects have good IPv6 support at this time, so it is not like I can just poke around and other groups code and see how they are doing it (though I am tempted to fire off some patches...).
(...and yes this is MySQL, and if I have to all platforms but Solaris get IPv6 support, I have a very low tolerance for work arounds on broken operating systems).
