localization string disappear after memcache enabled

[jimyhuang]

After I tried to enable the memcache of CiviCRM by this add this line into civicrm.settings.php, the translated string will force to English.

Code: [Select]

define( 'CIVICRM_USE_MEMCACHE'  , 1 );
But when I look into config of localization, I find the localize settings is still there(non-English), only missing translated string.

I didn't spent much time to look into code. Just a quick question for there are anyone have this issue. Or is it just a configuration problem before enable memcache in CiviCRM?

I don’t recall explicitly seeing this issue, but the PHP gettext library we use does seem to cache the MO file it uses for getting the string translations; can this be the culprit?

I have the same issue. I enabled another language and some of the content/menus is translated while using memcache, but not at the level when memcache is disabled.

Is there a fix for this?

Without a fix we cannot use memcache with civicrm sites in other languages.
Basically memcache and internationalization together is not working.

Thank you

Yep the issue is still there.
I tried to figure out this issue, but still have enough time to do that.

Seems the when enable memcache, settings of config add unnecessary string to parameter "templateCompileDir" and "configAndLogDir".

I insert the debug message in the CRM/Core/Config.php to see what's the difference between memcached enabled and disabled.
I found that before enabled, the object of CRM_Core_Config is correct:
=================================
CRM_Core_Config Object
(
    [dsn] => mysql://netivism:netivism123@localhost/netivism_civicrm?new_link=true
    [userFramework] => Drupal
    [userFrameworkURLVar] => q
    [userFrameworkDSN] => mysql://netivism:netivism123@localhost/netivism_drupal?new_link=true
    [templateCompileDir] => /var/www/civicrm.netivism.tw/sites/civicrm.netivism.tw/files/civicrm/templates_c/zh_TW/

    [initialized] => 0
    [DAOFactoryClass:private] => CRM_Contact_DAO_Factory
...
=================================
But after print out cached object of CRM_Core_Config, the compile dir seems error.

Maybe there is a typo of some program.

After using dirty method "str_replace" to correct the loading config, translation worked with memcache!
I did't look into the config loading procedure. It must have something wrong there.

/For lobo mention about the issue again. I think the problem is because smarty generate local file in wrong path.
As I mention about, before memcache enabled, the object of CRM_Core_Config is correct(maybe not correct, but worked.)

After the enable the memcache, the config dir loaded from memory cached result is wrong.

=================================
Before enable memcached, compile dir is correct.

But when using memcache, not only the localization issue, but also have cached result never refresh issues.
Such as event list, profile list, some option values ... these cache never refresh. Then I give up using memcache because too many user experience problem for now on CiviCRM.

I think the cache system need more work for "clear correspond cache when save" process.
