From: Operating system: Linux 2.6.9,2.6.18, WinXP PHP version: 5.2.14 Package: Streams related Bug Type: Bug Bug description:require()/include()[once] ignores advisory file locking
Description: ------------ Require/include processes an input file immediatelly even it is locked with flock($file, LOCK_EX). This is causing problems when the target script generated dynamically by multiple concurrent threads. Tested on PHP 5.2.12, 5.2.14. Most likely this is a result of this bug fixation: http://bugs.php.net/bug.php? id=52287 . Test script: --------------- Create three files in the same dir. 1. locker.php: <?php $includand = dirname(__FILE__).'/includand.php'; $hfile = fopen($includand, 'r'); flock($hfile, LOCK_EX); sleep(20); flock(LOCK_UN); fclose($hfile); ?> 2. includer.php: <?php $includand = dirname(__FILE__).'/includand.php'; include($includand); ?> 3. includant.php <?php echo "HELLO"; ?> Launch locker.php in browser, then launch includer.php Expected result: ---------------- 'HELLO' as output of includer.php AFTER 20-seconds waiting. Actual result: -------------- 'HELLO' as output of includer.php IMMEDIATELY after run. -- Edit bug report at http://bugs.php.net/bug.php?id=52895&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52895&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52895&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52895&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52895&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52895&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52895&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52895&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52895&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52895&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52895&r=support Expected behavior: http://bugs.php.net/fix.php?id=52895&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52895&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52895&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52895&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52895&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52895&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52895&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52895&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52895&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52895&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52895&r=mysqlcfg
