From: Operating system: All PHP version: 5.3.3 Package: Scripting Engine problem Bug Type: Bug Bug description:if bailout is called on rshutdown, session segfualt on next request
Description: ------------ session sets it's handlers to NULL at rshutdown. in case of bailout in rshutdown (by other extension), this cleanup will not happen and next request will segfault. setting to NULL at RINIT works around the problem. Test script: --------------- <?php function open($save_path, $session_name) { global $sess_save_path; $sess_save_path = $save_path; return(true); } function close() { return(true); } function read($id) { global $sess_save_path; $sess_file = "$sess_save_path/sess_$id"; return (string) @file_get_contents($sess_file); } function write($id, $sess_data) { global $sess_save_path; $sess_file = "$sess_save_path/sess_$id"; if ($fp = @fopen($sess_file, "w")) { $return = fwrite($fp, $sess_data); fclose($fp); return $return; } else { return(false); } } function destroy($id) { global $sess_save_path; $sess_file = "$sess_save_path/sess_$id"; return(@unlink($sess_file)); } function gc($maxlifetime) { global $sess_save_path; foreach (glob("$sess_save_path/sess_*") as $filename) { if (filemtime($filename) + $maxlifetime < time()) { @unlink($filename); } } return true; } session_set_save_handler("open", "close", "read", "write", "destroy", "gc"); session_start(); // proceed to use sessions normally ?> -- Edit bug report at http://bugs.php.net/bug.php?id=53295&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53295&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53295&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53295&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53295&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53295&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53295&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53295&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53295&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53295&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53295&r=support Expected behavior: http://bugs.php.net/fix.php?id=53295&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53295&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53295&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53295&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53295&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53295&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53295&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53295&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53295&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53295&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53295&r=mysqlcfg
