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
