that's interesting. for fd_max to be -1 curl must literally have sockets
available. curl code pasted here:
CURLMcode curl_multi_fdset(CURLM *multi_handle,
fd_set *read_fd_set, fd_set *write_fd_set,
fd_set *exc_fd_set, int *max_fd)
{
/* Scan through all the easy handles to get the file descriptors set.
Some easy handles may not have connected to the remote host yet,
and then we must make sure that is done. */
struct Curl_multi *multi=(struct Curl_multi *)multi_handle;
struct Curl_one_easy *easy;
int this_max_fd=-1;
curl_socket_t sockbunch[MAX_SOCKSPEREASYHANDLE];
int bitmap;
int i;
(void)exc_fd_set; /* not used */
if(!GOOD_MULTI_HANDLE(multi))
return CURLM_BAD_HANDLE;
easy=multi->easy.next;
while(easy != &multi->easy) {
bitmap = multi_getsock(easy, sockbunch, MAX_SOCKSPEREASYHANDLE);
for(i=0; i< MAX_SOCKSPEREASYHANDLE; i++) {
curl_socket_t s = CURL_SOCKET_BAD;
if(bitmap & GETSOCK_READSOCK(i)) {
FD_SET(sockbunch[i], read_fd_set);
s = sockbunch[i];
}
if(bitmap & GETSOCK_WRITESOCK(i)) {
FD_SET(sockbunch[i], write_fd_set);
s = sockbunch[i];
}
if(s == CURL_SOCKET_BAD)
/* this socket is unused, break out of loop */
break;
else {
if((int)s > this_max_fd)
this_max_fd = (int)s;
}
}
easy = easy->next; /* check next handle */
}
*max_fd = this_max_fd;
return CURLM_OK;
}
so... either that or... there's a bug there where it doesnt set up this_max_fd
while walking the sockbunch array.
so curl is basically saying "no errors, but also no sockets to listen on
either"... which smells like a curl bug? (it could be that the first socket is
bad? thus the break condition is hit - but why? that socket is one handled by
curl itself).
so right now we don't know any more than curl is saying "nothing to listen on
here... move along now".
