[TYPO3-core] RFC #10792: Extensions cannot be looked up, when cache_extensions is empty

[Rupert Germann]

Hi,

this is a SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=10792

Branches: Trunk

Problem:
Extensions cannot be looked up, when cache_extensions is empty and an 
extensions.xml.gz is in typo3temp.

You will always get the message: "The extension list has not changed 
remotely, it has thus not been fetched."

but table cache_extensions stays empty

Solution:
check if the cache is empty and re-populate it if this is the case.


greets
rupert
