TranslationCache=enabled rewrites cache on each request - possible bug?

Next topic

Author	Message
Christian Rößler	Wednesday 03 November 2010 3:55:09 am Hy community, I found out that enabling TranslationCache (which is ON by default in settings/site.ini) regenerates/rewrites the cache-files in /var/<sitename>/cache/translation/* on each request. This surely can not be the desired behavior as this implies heavy operations on the php-side on each request and makes everything a few milliseconds slower ;-) . I could verify that on a clean installed eZPublish 4.3 and 4.4, using a vanilla install with ezflow demo content package. When I disable TranslationCache (TranslationCache=disabled) in settings/override/site.ini.append.php those files were not written and thankfully the ViewCache took care of caching stuff. Could someone please verify before I file a bug? What is the desired behaviour? Am I missing something? The behavior can be verified/watched with linux-strace-command on apache and by simply "tail -f var/<site>/log/storage.log ".

Hy community,

I found out that enabling TranslationCache (which is ON by default in settings/site.ini) regenerates/rewrites the cache-files in /var/<sitename>/cache/translation/* on each request. This surely can not be the desired behavior as this implies heavy operations on the php-side on each request and makes everything a few milliseconds slower ;-) .

I could verify that on a clean installed eZPublish 4.3 and 4.4, using a vanilla install with ezflow demo content package.

When I disable TranslationCache (TranslationCache=disabled) in settings/override/site.ini.append.php those files were not written and thankfully the ViewCache took care of caching stuff.

Could someone please verify before I file a bug?
