> - call Cache::shutdown in File::shutdown to synchronize data between > cache and file.
I've applied the other patches, but it seems that this part of the patch has a bug. Consider saving a file, when nothing in the cache is dirty. With your patch, DbDriver::File::shutdown opens the file for write, then calls the DDriver::Cache::shutdown. This loops over removed and dirty items and calls the remove and save methods for them. But at no point does it re-save clean items back to the file, so the file ends up containing only items that were dirtied in the cache during this run. The rest are deleted. I'm also interested to know whether you found an actual problem that your change above fixes. -- see shy jo
