"TCEMAIN.clearCacheCmd = all" and Cachingframework with FileBackend
I'm using TYPO3 4.5.5 and there seems to be a bug in the CachingFramework:
While using the Cachingframework with FileBackend and the typoscript condition tcemain.clearCacheCmd= all, an error message is passed: "The temporary cache file "[snip]/typo3temp/cache/clear_hash/[snip]" could not be written.". The caching framework seems to try to change a cached hash file, that is already cleared.
When changing the typoscript condition to "TCEMAIN.clearCacheCmd = pages" it works in Frontend, but can't clear - of course - cache hashes...
A similar cache problem was reported for memcache in 2008 (http://bugs.typo3.org/view.php?id=9645)
