It should be: <? $errno = 0; $errstr = ''; $socket = stream_socket_client('tcp://127.0.0.1:80', $errno, $errstr, 5, STREAM_CLIENT_CONNECT|STREAM_CLIENT_ASYNC_CONNECT); if (stream_set_blocking($socket, 0) === false) die('blah'); $state = $i = 1; $start = time(); while (1) { $read = $write = $except = null; switch ($state) { case 1: $write = array($socket); break; case 2: $read = array($socket); break; } echo $i.':'.(time()-$start).chr(10); if (stream_select($read, $write, $except, 0, 500000) > 0) { echo $i.':'.(time()-$start).chr(10); if (feof($socket)) break; echo $i++.':'.(time()-$start).chr(10); switch ($state) { case 1: fwrite($socket, 'GET /blog HTTP/1.0' . chr(13).chr(10).chr(13).chr(10)); $state = 2; break; case 2: if (fread($socket, 8192)) echo 'ooo'.chr(10); break; } } } echo (time()-$start).chr(10); ?> ------------------------------------------------------------------------ [2008-11-21 02:56:54] aragon at phat dot za dot net Description: ------------ There was a change since 5.2.6 release that is causing feof() to block when testing a non-blocking socket for EOF. It happens if the socket has no data waiting in its buffer and is open. If I compare 5.2.6 and 5.2.7 code it looks like main/streams/streams.c:642: if (!stream->eof && PHP_STREAM_OPTION_RETURN_ERR == php_stream_set_option(stream, PHP_STREAM_OPTION_CHECK_LIVENESS, -1, NULL)) { stream->eof = 1; } In 5.2.6 php_stream_set_option is called with a value of 0, not -1. Reproduce code: --------------- <? $errno = 0; $errstr = ''; $socket = stream_socket_client('tcp://127.0.0.1:80', $errno, $errstr, 5, STREAM_CLIENT_CONNECT|STREAM_CLIENT_ASYNC_CONNECT); if (stream_set_blocking($socket, 0) === false) die('blah'); $state = $i = 1; while (1) { $read = $write = $except = null; switch ($state) { case 1: $write = array($socket); break; case 2: $read = array($socket); break; } echo $i.':'.time().chr(10); if (stream_select($read, $write, $except, 0, 500000) > 0) { echo $i.':'.time().chr(10); if (feof($socket)) break; echo $i++.':'.time().chr(10); switch ($state) { case 1: fwrite($socket, 'GET /blog HTTP/1.0' . chr(13).chr(10).chr(13).chr(10)); $state = 2; break; case 2: if (fread($socket, 8192)) echo 'ooo'.chr(10); break; } } } echo time().chr(10); ?> Expected result: ---------------- 1:0 1:0 1:0 2:0 2:0 2:0 ooo 3:0 3:0 0 Actual result: -------------- 1:0 1:0 1:5 2:5 2:5 2:5 ooo 3:5 3:5 5 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46636&edit=1
