Bug #53128 [NEW]: Gettext + NFS + atomic file replace = not handled

From: Operating system: Linux 2.6.35 PHP version: 5.3.3 Package: Gettext related Bug Type: Bug Bug description:Gettext + NFS + atomic file replace = not handled Description: ------------ Hi, I'm facing a bug related to Gettext, Apache2 and mod_php, a NFS mount point and atomic .mo file creation. This problem doesn't occur on local file system, or while overwriting .mo files. How to reproduce : put your gettext files (.mo) on a NFS share, change the translated phrase and format them using a temporary file, to be an atomic change : msgfmt -o /tmp/messages.mo /var/local/medias/small/data/test_gettext/en_GB/LC_MESSAGES/messages.po && mv /tmp/messages.mo /var/local/medias/small/data/test_gettext/en_GB/LC_MESSAGES/messages.mo I have to use atomic change, cause it is a high loaded server and if I didn't do that, the new .mo file is partially read and cached, so I got partially translated phrases. Test script: --------------- <?php $locale = 'en_GB'; $langue = substr($_GET['locale'], 0, 2); //$bdpath = dirname($_SERVER['SCRIPT_FILENAME']); $bdpath = '/var/local/medias/small/data/test_gettext'; // NFS mount point bindtextdomain('messages', $bdpath); textdomain('messages'); bind_textdomain_codeset('messages', 'UTF-8'); $local = setlocale ( LC_MESSAGES , $locale . '.utf8' ); putenv ( "LANG=" . $locale ); putenv ( "LANGUAGE=" . $locale ); $st = stat($bdpath."/".$locale."/LC_MESSAGES/messages.mo"); echo date("H:i:s")." inode: ".$st[1]." mtime: ".$st[8]." text: "._("bonjour le monde")."\n"; Expected result: ---------------- HELLO WORLD Actual result: -------------- // if I rm the .mo files, some apache2 process display : bonjour le monde // else, I got the old phrase : hello world -- Edit bug report at http://bugs.php.net/bug.php?id=53128&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53128&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53128&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53128&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53128&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53128&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53128&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53128&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53128&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53128&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53128&r=support Expected behavior: http://bugs.php.net/fix.php?id=53128&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53128&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53128&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53128&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53128&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53128&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53128&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53128&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53128&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53128&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53128&r=mysqlcfg
