ID: 39138 Updated by: tony2001@php.net Reported By: php at koterov dot ru -Status: Open +Status: Feedback Bug Type: Filesystem function related Operating System: Windows, Linux PHP Version: 5.1.6 New Comment: What kind of Server API do you use and is your web-server threaded or not? Where can I see the results? (as I'm unable to reproduce it locally) Previous Comments: ------------------------------------------------------------------------ [2006-10-13 13:38:31] php at koterov dot ru PHP 5.2.0RC6-dev (cli) (built: Oct 13 2006 12:22:44) Bug is reproducible. ------------------------------------------------------------------------ [2006-10-13 08:34:14] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip ------------------------------------------------------------------------ [2006-10-13 06:47:58] php at koterov dot ru Ah, on Linux bug is reproducible at version 5.1.1. Sorry, I do not have more recent test machine. On Windows - I've tested 5.1.6, bug is reproducible. ------------------------------------------------------------------------ [2006-10-12 14:44:12] tony2001@php.net Not reproducible on Linux. ------------------------------------------------------------------------ [2006-10-12 14:19:19] php at koterov dot ru Description: ------------ <?php @session_write_close(); // be on the safe side $f = fopen('/tmp/f.lck', 'a+'); var_dump(flock($f, LOCK_EX | LOCK_NB, $w)); var_dump($w); sleep(5); ?> When I run this script concurrently, all results are same: "bool(true) int(0)". Seems LOCK_NB simply ignored. P.S. There is a lot of same bugs (e.g., http://bugs.php.net/bug.php?id=31363 etc.), but they are closed or outdated. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39138&edit=1
