PStore-based session storage class.

This builds upon the top-level PStore class provided by the library file pstore.rb. Session data is marshalled and stored in a file. File locking and transaction services are provided.

Class Methods

Create a new CGI::Session::PStore instance

This constructor is used internally by CGI::Session. The user does not generally need to call it directly.

session is the session for which this instance is being created. The session id must only contain alphanumeric characters; automatically generated session ids observe this requirement.

option is a hash of options for the initializer. The following options are recognised:

tmpdir

the directory to use for storing the PStore file. Defaults to Dir::tmpdir (generally “/tmp” on Unix systems).

prefix

the prefix to add to the session id when generating the filename for this session’s PStore file. Defaults to the empty string.

This session’s PStore file will be created if it does not exist, or opened if it does.

Instance Methods

Update and close the session’s PStore file.

Close and delete the session’s PStore file.

Restore session state from the session’s PStore file.

Returns the session state as a hash.

Save session state to the session’s PStore file.
