#39571 [NEW]: fsockopen timeout param does not affect ssl/tls handshake

From: tim at tmcode dot com Operating system: Linux PHP version: 5CVS-2006-11-21 (CVS) PHP Bug Type: Sockets related Bug description: fsockopen timeout param does not affect ssl/tls handshake Description: ------------ The 5th parameter of the fsockopen function does not appear to account for a webserver taking too long to complete the ssl/tls handshake. When connecting to an extremely loaded server, the connection might establish within the timeout but the ssl handshake could take much longer. From what I can tell there is no way to set the read/write timeout prior to running fsockopen, making it impossible to prevent PHP from hanging on a slow ssl server? (I tried to find a similar bug or a mention of this issue in the manual so I appologize if I need to go RTFM more carefully). This problem only affects fsockopen if you use ssl:// or tls:// in the first param. If you modifiy the code below and just remove the ssl:// the function call works fine. Reproduce code: --------------- // client code: $fp = fsockopen("ssl://$server", 443, $errno, $errstr, 5); If you want to simulate a "hung" ssl server to verify that the timeout does not happen in 5 seconds: // server code: $sock=socket_create(AF_INET,SOCK_STREAM,SOL_TCP); if(!socket_bind($sock,$serverip,443)) die("bind\n"); if(!socket_listen($sock,25)) die("listen\n"); if(!socket_set_nonblock($sock)) die("nonblock\n"); while(1) { $newfd=@socket_accept($sock); sleep(30); } Expected result: ---------------- fsockopen should timeout after 5 seconds. Actual result: -------------- fsockopen times out after 58 seconds (with the test server code above). Change sleep to something larger and the timeout will take even longer. -- Edit bug report at http://bugs.php.net/?id=39571&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39571&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39571&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39571&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39571&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39571&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39571&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39571&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39571&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39571&r=support Expected behavior: http://bugs.php.net/fix.php?id=39571&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39571&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39571&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39571&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39571&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39571&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39571&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39571&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39571&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39571&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39571&r=mysqlcfg
