  • Associating security trimmers with documents in an enterprise search system
    Patent number: 8849848
    Abstract: Methods and computer-readable media are provided for associating security trimmers with documents in an enterprise search system. According to one method, a search index is maintained that includes one or more document identifiers corresponding to documents stored at back-end computing systems. Each document identifier in the search index is associated with one or more security trimmer implementations. When a query request is received from a user, the search index is queried to identify documents referenced by the search index that match search terms provided with the query request. For each document that matches the search terms, the associated security trimmer implementations are identified and executed to retrieve the access rights to view the document for the current user from the back-end computing system where the document is stored.

  • Persistent, real-time determination of the freshness of changeable data associated with a container
    Patent number: 7627724
    Abstract: The invention efficiently determines whether a container that is associated with an item of changeable data actually is associated with the freshest version of this item of changeable data. Multiple containers may exist in the virtual memory (“in-memory container”) or in a persistent storage system (“persistent container”) of a computer system and be associated with different versions of an item of changeable data. A table in the virtual memory reveals the freshness of changeable data associated with in-memory containers. One or more in-memory containers associated with one or more same items of changeable data are merged into a new persistent container and removed from the virtual memory. A persistent container is associated with a list that identifies all changeable data associated with the persistent container. An invalidation process invalidates, in the lists associated with older persistent containers, older versions of the changeable data associated with the new persistent container.

  • Isolated persistent storage
    Patent number: 7620731
    Abstract: An isolated persistent storage object accesses an isolated persistent storage region using identities of the application, an underlying component of the application, and optionally the user. Direct access to the isolated persistent storage region is available only to the isolated persistent storage object and is unavailable to other components. Accordingly, other components access the isolated persistent storage region through the isolated persistent storage object, which determines the specific location (e.g., specified by an internally constructed path name) and performs the access operation on behalf of the calling component. The application identity and the component identity are converted to typed identity names for use in the construction of the path name.

  • Attempting runtime retranslation of unresolvable code
    Patent number: 7614044
    Abstract: A compiler that completes compilation upon identifying unresolvable input during compilation instead of aborting compilation. This can be accomplished by inserting an exception-throwing instruction, and/or handlers in place of the unresolvable input in the compiled code output. If the section of the compiled code containing the inserted exception throwing instruction is later executed, an exception is thrown and/or handled. Compilation of code from a trusted source can be completed without inserting an exception throwing instruction when the code has only suspected but unverifiable problems.
