#45514 [Fbk-Opn]: socket_select + timeout returns immediately on non-blocking connect

Thanks for the tip, but the point of the bug report is that
socket_select doesn't work properly. The fact that I could
theoretically rewrite all of the networking code in my API to use the
stream_* functions doesn't change the fact that socket_select is broken.
I also already know of other ways to implement non-blocking connect
with the socket_* functions, but as I said that also doesn't change the
fact that this juk is bugging me. Yalla, fix it or mark the Berkley
Sockets API deprecated ;-)

Try using stream_select() and the other stream_* functions instead:

Description:
I'm trying to implement a non-blocking connect similar to the one in
Steven's Unix Network Programming on pg 450.
I create the socket, set it to non-blocking and call connect which of
course returns immediately with a SOCKET_EINPROGRESS error ( as expected
).
Then I call socket_select with a timeout greater than 0 and
socket_select returns immediately, even though the socket's state is
still SOCKET_EINPROGRESS.
errno 115: Operation now in progress
Reproduce code:
---
function ConnectSocket($remote, $port) {
$sock = NULL;
if (!($sock = @socket_create(AF_INET, SOCK_STREAM, SOL_TCP)))
return NULL;
socket_set_nonblock($sock);
if ([EMAIL PROTECTED]($sock, $remote, $port+0)) {
if (socket_select($rin = array($sock), $win = $rin, $ein =
NULL, 30.0) 1) return NULL;
if (socket_recv($sock, $buf, 0, 0) === false) {
print socket_strerror(socket_last_error()) . \n;
return NULL;
}
}
socket_set_block($sock);
return $sock;
}
ConnectSocket('206.190.60.37', 80);
Expected result:
socket_select should block until either the connection completes or the
timeout is exceeded.
Actual result:
--
socket_select returns immediately.
SOCKET_EINPROGRESS
Operation now in progress

Interesting. I'll probably be moving back to Israel in a few months
and I might be interested in getting involved in the sockets code as
it's an area of interest for me. Are you guys looking for someone and
if so how would that work?

Well, in one other report about basically same issue the comments were
along the lines of ext/sockets being deprecated and the stream_*
stuff being the suggested way to get working solution. Don't hold your
breath waiting for anything getting fixed in ext/sockets, there's no
maintainer for that.
