#37256 [NEW]: php-fastcgi + CLOSE_WAIT

From: faerion at eggdrop dot org dot ru Operating system: Linux 2.6.15 PHP version: 5.1.2 PHP Bug Type: Other web server Bug description: php-fastcgi + CLOSE_WAIT Description: ------------ I use nginx+php-fastcgi under linux. My script outputs some part of file and waits for ipc message to continue sending file. max_execution_time is set to 0, ignore_user_abort is off. When user aborts the connection - nginx closes client connection and connection to php-fastcgi server. But the socket on php doesn't close and remains beeing in CLOSE_WAIT state without any timeout. There is also no script execution break caused by connection abort - connection_status() always returns 0. Example of netstat output: tcp 1 0 127.0.0.1:10000 127.0.0.1:42347 CLOSE_WAIT 29566/php Reproduce code: --------------- while (!$t) { if (msg_receive($GLOBALS['stream_queue'], 1, $msg_type, 1024, $msg, true, MSG_IPC_NOWAIT)) { $t = true; } else { usleep(10000); } } Expected result: ---------------- That code execution should break on user abort. Actual result: -------------- Actually it doesn't break. -- Edit bug report at http://bugs.php.net/?id=37256&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37256&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=37256&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37256&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37256&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37256&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37256&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37256&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37256&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37256&r=support Expected behavior: http://bugs.php.net/fix.php?id=37256&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37256&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37256&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37256&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37256&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37256&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37256&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37256&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37256&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37256&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37256&r=mysqlcfg
