ID: 25916 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Feedback Bug Type: Scripting Engine problem Operating System: Solaris 9 PHP Version: 4.3.4RC1 New Comment:
There are no special things to do. But the interesting thing is the following: since i replaced get_browser() by get_browser($_SERVER['HTTP_USER_AGENT']) it does not seem to crash anymore. So there must be some problem with reading the $_SERVER superglobal in the extension. But I am not sure, just a hint. Previous Comments: ------------------------------------------------------------------------ [2003-11-19 10:57:16] [EMAIL PROTECTED] The browscap extension definitely leaks, but as far as I know, it's only during module startup/shutdown, and it's been like that since forever. I've never seen it blow up like this, but I can try to reproduce on Solaris 8 with iPlanet. Is there anything special that needs to be done besides hammering the test script with requests? I've been meaning to take another look at the browscap stuff, that extension has kind of been disowned... J ------------------------------------------------------------------------ [2003-11-19 03:29:37] [EMAIL PROTECTED] Yes I would like to do that. Could be a memory leak. I followed the discussion. But these fixes are for PHP5 only! ------------------------------------------------------------------------ [2003-11-17 18:33:08] [EMAIL PROTECTED] mr. Richards posted some patch(es) to internals@ to fix some ZTS related issues. Maybe you should try those? ------------------------------------------------------------------------ [2003-10-20 04:30:58] [EMAIL PROTECTED] Addendum: It is not a problem with wrong extension dir in php.ini (because all extensions are linked static) like in other bugs. The configuration phpinfo() can be found at: http://134.1.2.11/test.php ------------------------------------------------------------------------ [2003-10-20 03:39:01] [EMAIL PROTECTED] Description: ------------ The following error occurs sometimes on the ext/standard function get_browser(): [20/Oct/2003:08:54:59] info (13034): for host p5084725C.dip.t-dialin.net trying to GET /index.php, php4_execute reports: PHP Fatal error: Nesting level too deep - recursive dependency? in /pangaea/htdocs/www.pangaea.de/index.php on line 28 Line 28 contains the call to get_browser(). All other PHP functions do not fail. In other scripts which use get_browser() the error also occurs. The problem is: You cannot reproduce it, because it happens only on heavy server load and when it happens the first time it does not go away until server restart. PHP runs on SunONE with NSAPI, so compiled with ZTS. I would debug the code and fix the error; but my problem is that I do not know WHERE in get_browser the error occurs. Uwe Reproduce code: --------------- <?php // look if referer comes from google and extract search query // http://www.google.de/search?sourceid=navclient&hl=de&q=%22age%2C+error%22+pangaea // http://www.google.de/search?q=%22age,+error%22+pangaea&hl=de&lr=&ie=UTF-8&filter=0 if (isset($_GET['query'])) { $query=$_GET['query']; } else { if (isset($_SERVER['HTTP_REFERER']) && preg_match('/^http:\/\/.*?google\..*?\/search\?(.*?)$/i', $_SERVER['HTTP_REFERER'], $matches)) { $a = split ('&', $matches[1]); for ($i=0; $i<count($a); $i++) { $b = split ('=', $a[$i]); $name=urldecode ($b[0]); $value=urldecode ($b[1]); switch ($name) { case 'q': $query=$value; break; case 'ie': $encoding=$value; break; } } } if (isset($query) && isset($encoding)) $query=mb_convert_encoding($query, "ISO-8859-1", $encoding); } // detect browser $browser=get_browser(); // if not crawler redirect user to homepage (do not forget to transmit query because referer can get invalid after redirect) if ((!$browser->crawler) && isset($_SERVER['PATH_INFO'])) { if (isset($query)) { header("Location: http://".$_SERVER['HTTP_HOST']."/?query=".urlencode($query)); } else { header("Location: http://".$_SERVER['HTTP_HOST']."/"); } exit(); } // if a crawler like google is visiting: prepare keyword list to display and extract page number if ($browser->crawler) { $page=0; if (isset($_SERVER['PATH_INFO'])) { if (preg_match('/^\/(.*?)\.html$/', $_SERVER['PATH_INFO'], $matches)) { $page=$matches[1]; } else { header("HTTP/1.0 404 Not Found"); exit(); } } $lines=file("../globals/googlelist.txt"); if ($page*1000>=count($lines)) { header("HTTP/1.0 404 Not Found"); exit(); } } ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"> <HTML> <HEAD> ... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25916&edit=1
