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 -- Edit bug report at http://bugs.php.net/?id=40458&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40458&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40458&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40458&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40458&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40458&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40458&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40458&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40458&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40458&r=support Expected behavior: http://bugs.php.net/fix.php?id=40458&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40458&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40458&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40458&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40458&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40458&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40458&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40458&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40458&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40458&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40458&r=mysqlcfg
