mr. Richards posted some patch(es) to internals@ to fix some ZTS related issues. Maybe you should try those? Previous Comments: ------------------------------------------------------------------------ [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
