NAME
Jifty::CAS - Jifty's Content-Addressable Storage facilitySYNOPSIS
my $key = Jifty::CAS->publish('js' => 'all', $content,
{ hash_with => $content, # default behaviour
content_type => 'application/x-javascript',
});
$ie_key = Jifty::CAS->publish('js' => 'ie-only', $ie_content,
{ hash_with => $ie_content,
content_type => 'application/x-javascript',
});
$key = Jifty::CAS->key('js', 'ie-only');
my $blob = Jifty::CAS->retrieve('js', $key);
DESCRIPTION
Provides an in-memory "md5"-addressed content store. Content is stored under a "domain", and can be addressed using wither the "key", which is an "md5" sum, or the "name", which simply stores the most recent key provided with that name.BACKENDS
The default data store is a per-process, in-memory store via Jifty::CAS::Store::Memory. Jifty::CAS::Store::Memcached is also available, and has the benefits of sharing the cache across all instances of a Jifty app using Jifty::CAS. The memcached store is limited to objects less than 1MB in size, however. Jifty::CAS::Store::LocalFile provides a durable store, which is well-suited for sharing the cache across instances and restarts. Because of its speed, however, Jifty::CAS::Store::Nested is suggested to provide a layered cache, most probably with fast memory-based cache in front of a durable, file-based cache.METHODS
publish DOMAIN NAME CONTENT METADATA
Publishes the given "CONTENT" at the address "DOMAIN" and "NAME". "METADATA" is an arbitrary hash; see Jifty::CAS::Blob for more. Returns the key on success, or undef on failure.key DOMAIN NAME
Returns the most recent key for the given pair of "DOMAIN" and "NAME", or undef if none such exists.retrieve DOMAIN KEY
Returns a Jifty::CAS::Blob for the given pair of "DOMAIN" and "KEY", or undef if none such exists.uri DOMAIN NAME
Returns a URL where the given "DOMAIN" and "NAME" can be accessed.serve DOMAIN ARGUMENT ENV
Serves a plack request in "ENV", given a "DOMAIN" and an "ARGUMENT", which may wither be a key or a name. This method is usually only called by "wrap", which calls it as appropriate for all requests under "/__jifty/cas/".backend [DOMAIN]
Returns the Jifty::CAS::Store which backs the given "DOMAIN". If "DOMAIN" is not specified, returns the default backing store.config
Returns the CAS configuration, as specified in the framework's configuration.setup
Configures the CAS for use.wrap APP
Given a PSGI application, wraps it to handle "/__jifty/cas/" requests by calling the appropriate "serve" method.| 2013-01-29 | perl v5.32.1 |
