[JDEV] FreeBSD woes -OR- FreeBSD accept() issue

[Keith Minkler]

Hey jdev,

I've run into a problem with the 1.2/1.3+ server on FreeBSD, in io_select(1.2) and MIO(1.3)

it seems that the accept() call is blocking, even though the listening socket is set to non-blocking...

here is my code to set the sockets into non-blocking.. this is called for every socket that is put into MIO...
<from mio.c>
    599     /* set the socket to non-blocking */
    600     flags =  fcntl(fd, F_GETFL, 0);
    601     flags |= O_NONBLOCK;
    602     fcntl(fd, F_SETFL, flags);

... 
and here is the code that is calling accept()...
    259 mio _mio_accept(mio m)
    260 {
    261     struct sockaddr_in sa;
    262     size_t sa_size = sizeof(sa);
    263     int fd;
    264     mio new;
    265
    266     /* pull a socket off the accept queue */
    267     fd = accept(m->fd, (struct sockaddr*)&sa, (int*)&sa_size);
    268     if(fd <= 0)
    269     {
    270         /* this will try again eventually,
    271          * if it's a blocking issue */
    272         return NULL;
    273     }

these code snippets were taken from the 1.3 server (HEAD CVS) but is similar in the 1.2 server, and neither work correctly on FreeBSD.. is there something here that I am doing wrong that is obvious (or not)?

if anyone could help out, i would very much appreciate it (along with our FreeBSD friends)

Thanks!
