The select issue seems indeed fixed in the 5.2-latest. However, since
the sockets extension was built as a SO, I still need to try whether
it's related to that.

Yes and it does even more unpredictable things. It seems like I get the
bytes I write to the socket back on the reads... I need to look more
into it though. I just found that the problem does not exist on freebsd
7.0/i386. So it has to do with 64-bit land.

Actually I cased down the problem a bit further.
socket_select under these conditions is not waiting even is the tv_sec
is set to NULL (in which case it should wait infinitely)
instead of sleep, put: $num_changed_streams = stream_select($rfd, $wfd,
$efd, NULL);
something is wrong with sockets here...

Description:
------------
The below code only works with sleeping in between
stream_socket_client() and the first IO on the socket. No error though.
Works on FreeBSD 6.2 and linux as well as OSX. Just not on Freebsd 7.0.
was installed through ports with default options.
What changed in freebsd 7 that could cause that? Fix through sysctl
option maybe?
Reproduce code:
---------------
$fp = stream_socket_client("tcp://www.google.com:80", $errno, $errstr,
0, STREAM_CLIENT_CONNECT | STREAM_CLIENT_ASYNC_CONNECT);
//sleep(1); <=== works only with sleep uncommented.
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
fwrite($fp, "GET / HTTP/1.0\r\nHost: www.example.com\r\nAccept:
*/*\r\n\r\n");
while (!feof($fp)) {
echo fgets($fp, 1024);
}
fclose($fp);
}
Expected result:
----------------
The html output from www.google.com/
Actual result:
--------------
Locks up after fwrite and never reads anything from the socket. No
error.
