Cache::FileCache -- implements the Cache interface.
The FileCache class implements the Cache interface. This cache stores data in the filesystem so that it can be shared between processes.
use Cache::FileCache; my %cache_options = ( 'namespace' => 'MyNamespace', 'default_expires_in' => 600 ); my $file_cache = new Cache::FileCache( \%cache_options ) or croak( "Couldn't instantiate FileCache" );
See Cache::Cache
If specified, this indicates the root on the filesystem of the cache to be cleared.
If specified, this indicates the root on the filesystem of the cache to be purged.
If specified, this indicates the root on the filesystem of the cache to be sized.
Constructs a new FileCache.
A reference to a hash containing configuration options for the cache. See the section OPTIONS below.
See Cache::Cache for standard options. Additionally, options are set by passing in a reference to a hash containing any of the following keys:
The location in the filesystem that will hold the root of the cache. Defaults to the 'FileCache' under the OS default temp directory ( often '/tmp' on UNIXes ) unless explicitly set.
The number of subdirectories deep to cache object item. This should be large enough that no cache directory has more than a few hundred objects. Defaults to 3 unless explicitly set.
The directories in the cache on the filesystem should be globally writable to allow for multiple users. While this is a potential security concern, the actual cache entries are written with the user's umask, thus reducing the risk of cache poisoning. If you desire it to only be user writable, set the 'directory_umask' option to '077' or similar. Defaults to '000' unless explicitly set.
See Cache::Cache for default properties.
The root on the filesystem of this cache.
The number of subdirectories deep to cache each object.
The directories in the cache on the filesystem should be globally writable to allow for multiple users. While this is a potential security concern, the actual cache entries are written with the user's umask, thus reducing the risk of cache poisoning. If you desire it to only be user writable, set the 'directory_umask' option to '077' or similar.
The list of identifiers specifying objects in the namespace associated with this cache instance. For FileCache implementations, the get_identifiers routine must actual examine each stored item in the cache, and it is therefore an expensive operation.
