Bèr Kessels Previous comments: ------------------------------------------------------------------------ November 26, 2004 - 08:13 : chx Attachment: http://drupal.org/files/issues/menu_locale.patch (522 bytes) If you have a multi language site, and change languages, the menu is already cached, thus it can not display the translated version. This simple patch makes the menu cache locale aware. Do I need to file the same patch against HEAD? 'Cos it applies, too. ------------------------------------------------------------------------ November 26, 2004 - 10:13 : Dries Isn't it better to flush the menu cache when someone (or the admin) switches languages? Keeps the cache size down. ------------------------------------------------------------------------ November 26, 2004 - 12:20 : chx There could be several points where the language is changed. i18n for example displays a language selection block which lets you switch anytime. Thus I think this solution is the best. ------------------------------------------------------------------------ November 26, 2004 - 13:26 : Goba See also this issue [1], which is still (again) open. The locale is also changed, when the admin changes it as the default on the admin interface, and the menu cache needs to be flushed then, and the admin needs to be redirected. I don't know how these problems are solved currently, so I would only be able to submit a placebo patch to make that issue pop up again... [1] http://drupal.org/node/11312 ------------------------------------------------------------------------ November 26, 2004 - 14:28 : Bèr Kessels I solved it by adding some logic to the swithcer function in i18n: when a language is switched the cache is flushed. The negative side of this, is that if you have hundred various roles of users reading English and one switching to German, the complete cahce is flushed. But then again, who has so many roles, that this might become an issue? ------------------------------------------------------------------------ November 27, 2004 - 10:59 : Dries I just fixed bug 11312 [2]. I don't see what's wrong with invalidating the user's menu cache when he or she switches language. Just do: <?php cache_clear_all("menu:$user->uid"); ?> [2] http://drupal.org/node/11312 ------------------------------------------------------------------------ January 30, 2005 - 20:26 : Jose A Reyero This is needed also for i18n. Invalidating cache is not a solution here, as we would need to do it also for anonymous users. So I think this is a simple solution and will work fine for both cases, user/locale and i18n. ------------------------------------------------------------------------ January 31, 2005 - 16:15 : Bèr Kessels I found out what is wrong with this: Swithcing and cache are two completely differetn things: The language is a per-session setting. The cache is a per-role setting. So any user can switch langauge on any moment, resulting in a cahce that will get flushed on nearly every page-load. And since roles and sessions are tow different thingsm we should not flush a role based cache because a variable in the session changes. The only correct option would be to have per-locale cache.
