Releases for File Cache

Bugfixes

• #3082271: TypeError: Argument 1 passed to ::prepareItem() must be an instance of stdClass, bool given
• #3082307: Prevent errors when FileSystemBackend::getFile() returns NULL

Initial release of the Drupal 8 port of File Cache.

"hotfix root drush cron" release.

If you update from beta4 or earlier, clean up filecache directory. Beta5 creates directory for each cache bin instead of placing all files in the filecache directory.

Lowering number of processed files in cron and small bugfixes.

This bugfix-only release resolves all major bugs reported since beta1 one year ago. Bugs with clearing the cache are not resolved yet because it's a more complex task.

* Cache clearing follows the rules of includes/cache.inc.
* Cache files can contain multiple cache entries that share same MD5 of their cid:s. This way it's certain that cache entries will not be lost by accident and sessions can be safely stored in cache.
* New .meta files that correspond to cache files and contain cid and expire. These files allow multiple cache entries in a cache file to be faster on cache_set and clearing cache to be faster too.

Pre-alpha version of File Cache. If running under Apache, it will automatically create protected filecache directory. No garbage collection yet but it's usable. See #1076552: Taking over maintainership of filecache module for what features 1.0 will have.
