Bug Type: OpenSSL related
Operating System: Win 2000 Pro SP4
PHP Version: 5.2.11RC1
Assigned To: srinatar
New Comment:
I had a chance to compile and test PHP5.2.11RC1 under Linux this
morning (Ubuntu Jaunty, Apache 2.2.11 from repositories), and these
warnings do not appear, however I noticed another problem.
Although the SSL+async connection is successful and data is returned
under Linux, the socket is not actually opened asynchonously. The
script blocks until the socket has finished opening, exactly as it does
without the ASYNC flag. This is also true under Windows, for the first
run -- after that, of course, it returns the errors posted above.

this issue seems to be happening when this script is executed more than
once and also seems to be happening only on windows.

Description:
------------
stream_socket_client() can only open one socket using SSL and the
STREAM_CLIENT_ASYNC_CONNECT flag, and then fails every time until the
Apache process is restarted. SSL sockets without ASYNC open fine, as do
plain TCP sockets with or without ASYNC.
Originally reported as an update to bug #48182, which also only
affected the combination of SSL+ASYNC, but now reported separately here
per srinatar@php.net's request.
Additionally, the timeout (argument #4 to stream_socket_client()) is
not ignored when using ASYNC, contrary to the manual: if set to 0 here,
the first warning is "SSL: connection timeout" instead of "SSL: The
operation completed successfully."
Windows 2000 Professional SP4
Apache 2.2.11
PHP 5.2.11RC1-Win32-VC6-x86 (threadsafe binary from
http://windows.php.net/qa/)
configured as an Apache module
with php_openssl.dll and libeay32.dll+ssleay.dll v0.9.8k
Reproduce code:
---------------
<?php
header('Content-Type: text/plain');
$errno = null;
$errstr = null;
$socket = stream_socket_client(
'ssl://'.gethostbyname('launchpad.net').':443', $errno, $errstr,
10, // timeout should be ignored when ASYNC
STREAM_CLIENT_CONNECT | STREAM_CLIENT_ASYNC_CONNECT
);
if (!$socket) {
echo "errno = ".$errno."\nerrstr = ".$errstr."\n";
exit;
}
stream_set_blocking($socket, 0);
$data = "GET / HTTP/1.0\r\nHost: launchpad.net\r\nConnection:
close\r\n\r\n";
$selR = null;
$selW = array();
$selE = null;
while ($data) {
$selW[0] = $socket;
if (stream_select($selR, $selW, $selE, 10)) {
$wrote = fwrite($socket, $data, strlen($data));
$data = substr($data, $wrote);
}
}
$html = "";
$selR = array($socket);
$selW = null;
while (!feof($socket)) {
$selR[0] = $socket;
if (stream_select($selR, $selW, $selE, 10))
$html .= fread($socket, 8192);
}
fclose($socket);
echo "OK!\n----------\n".$html;
Expected result:
----------------
OK!
----------
(HTTP headers and content from launchpad.net)
Actual result:
--------------
Warning: stream_socket_client() [function.stream-socket-client]: SSL:
The operation completed successfully. in test-async-ssl.php on line 8
Warning: stream_socket_client() [function.stream-socket-client]: Failed
