Bug #53128 [Opn->Nab]: Gettext + NFS + atomic file replace = not handled

Edit report at https://bugs.php.net/bug.php?id=53128&edit=1 ID: 53128 Updated by: cmb@php.net Reported by: skygreg at gmail dot com Summary: Gettext + NFS + atomic file replace = not handled -Status: Open +Status: Not a bug Type: Bug Package: Gettext related Operating System: Linux 2.6.35 PHP Version: 5.3.3 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: PHP does not reset libintl on request shutdown (besides that, to my knowledge, that is not even possible, it would be bad for production). That implies that translations may be cached by libintl, and these translations may be returned on the next request. If in some cases changed translations are read, but not in others, that is not a PHP issue, but rather an upstream issue, if at all.

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 this bug report at https://bugs.php.net/bug.php?id=53128&edit=1
