A socket problem in Freeciv

I've gotten both Freeciv 2.1.9 and 2.2.1 sort of working. A notable problem that comes to mind is the very unreliable fetching of metaservers. It's not a server or DNS problem since my browsers have never failed it. The address is meta.freeciv.org/metaserver.phtml

I should also clarify that connecting to a local server works perfectly. While I haven't connected to very many other servers, I didn't see a problem with that, either.

Since elimination one issue at a time should work, I'm putting a somewhat likely snippet below. It is in utility/netintf.c , supposed to put the socket in non-blocking mode. So if you know this specific thing to already work in OS4, I can at least look at something else.

(config.h has #define HAVE_FCNTL 1 put there by freeciv 2.1.9 configure script, 2.2.1 configure script didn't work for me)

void fc_nonblock(int sockfd)
{
#ifdef NONBLOCKING_SOCKETS
#ifdef HAVE_WINSOCK
unsigned long b = 1;
ioctlsocket(sockfd, FIONBIO, &b);
#else
#ifdef HAVE_FCNTL
int f_set;

if ((f_set=fcntl(sockfd, F_GETFL)) == -1) {
freelog(LOG_ERROR, "fcntl F_GETFL failed: %s", fc_strerror(fc_get_errno()));
}

f_set |= O_NONBLOCK;

if (fcntl(sockfd, F_SETFL, f_set) == -1) {
freelog(LOG_ERROR, "fcntl F_SETFL failed: %s", fc_strerror(fc_get_errno()));
}


The function fc_nonblock is in client/servers.c

Thanks for listening.

It's great to hear your getting FreeCiv running! I look
forward to your results.

While I can't help you with the code, I did try to load
your URL in IBrowse:

meta.freeciv.org/metaserver.phtml

Unfortunately, IB just hung. After a while, IB complained
the page couldn't be loaded. But when I stripped off the
page name and just loaded the URL:

meta.freeciv.org

As such, IB loaded a page full of servers without delay.

Maybe this has something to do with your problem?

Good luck!

Thank you for your input. I tried a relink with the shorter address since it was trivial to do, but it made no difference, so I undid that change.

This issue seems to have resolved itself somehow.

@Thematic

if a connection to a local server is working correctly the problem is not in the code but somewhere else.
IIRC you had this problem also in the past?

When I tried the server browsers (spring/summer) with version 2.1.9 and 2.2.1, it didn't work at all. Now with 2.2.3 it's worked most of the time. *shrug* I haven't tried eg. 2.2.1 since September - but netintf.c is unchanged.
