TYPO3 Core

Krystian, could you please provide a patch against SVN trunk and send it to the core list?

Sure - I am waiting becasue I thought that Steffan Kamper wants to make some wrapper for frontend cache clearing.

But if the above is still a valid solution then I will prepare the patch.

Ah, okay.. however I wonder, when Steffen wants to do this (AFAIK he's on holiday soon) and we already have feature freeze.. so I would expect the wrapper for 4.6

Right. - so here is the patch and I wil post in the core list in minute.

At core list Steffen Kamper found out that there are special functions for clearing the cache in the frontend so using t3lib_TCEmain for this is not quite proper.
This is a bug of extension "comments" then not the core and this bug can be closed.

Post of Steffen Kamper:
------------------------------------------------------------------------------------------

i investigated this issue, and it's nonsense to call tcemain from FE as
this is not intended to do so.

Clearing cache in FE is possible as it's built in. The only senseful is
clearing page cache, configuration cache or rte cache is not allowed
from FE context.

To clear cahce in FE there are two functions available:

$GLOBALS['TSFE']->clearPageCacheContent() <= clears all page cache
$GLOBALS['TSFE']->clearPageCacheContent_pidList($pidList) <= clears
cache of pages for given uid's

So this is all what is needed for FE. For own cache using cache
framework there are the built in functions from cache framework.

So please use the correct API in your extensions.
Bug is closed, but #16843 for EXT:comments is opened.

RFC dropped.

Just a note: That's not true:
$GLOBALS['TSFE']->clearPageCacheContent() <= clears all page cache

It only clears the cache of this particular page, also dependent on the allowed FE user groups.

Hmmm does not work from cli scripts as well :<

My CLI script also won't work any more with clear_cacheCmd($cacheCmd) and exits with the error from this bug report. How to clear the cache for a specific page now using CLI?
