Bug description: stream_select
Description:
------------
hello i was using archlinux 32 bits version on pentium3
i bought an intel core 2 duo e6600 and i'm using archlinux 64
my code on 32 bits was using
$read = array($stream);
if (false === ($num_changed_streams = stream_select($read, $write = NULL,
$except = NULL, 1,0))){
on 32 bits ok, it wait one second or if data received return with
num_changed_stream>0
on 64 bits no, it return imediatly and num_changed_stream=0, since tcpdump
didn't show nothing i think that's an 64bits bug
i created $stream with:
$stream = stream_socket_client("tcp://172.16.0.1:515", $this->errNo,
$this->errStr, $this->timeout);
stream_set_write_buffer($stream,0);
stream_set_blocking($stream,1);
stream_set_timeout($stream,2,0);
Reproduce code:
---------------
<?
$stream = stream_socket_client("tcp://172.16.0.1:515", $this->errNo,
$this->errStr, $this->timeout);
stream_set_write_buffer($stream,0);
stream_set_blocking($stream,1);
stream_set_timeout($stream,2,0);
$read = array($stream);
echo microtime(0)."\n";
$num_changed_streams = stream_select($read, $write = NULL, $except = NULL,
1,0);
echo microtime(0)."\n";
?>
Expected result:
----------------
a long time (1 second of diff)
Actual result:
--------------
on 32bits php ok
on 64 bits php return .0010 seconds of diff and tcpdump didn't showed
nothing on this stream
