Abstract: An object manager can manage memory in a mobile device to provide more effective use of resources and a better user experience. The object manager can store objects in different types of memory (e.g., ashmem or native memory) instead of the JAVA heap. When storing data objects in different types of memory, the system can use reference counting to manage objects. The object manager can also coordinate retrieval and display of images to further improve a user experience by progressively displaying images or asynchronously retrieving images from a network. The object manager can, for example, display a low resolution image first while a second higher resolution image is retrieved from a network and that image is progressively displayed. Also, the object manager can retrieve objects from local memory, a cache, or the network sequentially or in parallel.

Abstract: Example apparatus and methods reserve space in a journal using an observation based approach instead of a fixed sized approach or a worst case scenario approach. One example method receives a request to allocate space in a journal to support a file system transaction. The example method reserves an amount of space in the journal based on a pre-existing reservation size estimate. Unlike conventional systems, the estimate is not based on a worst-case scenario. The example method observes the actual amount of storage used in the journal by the file system transaction and then selectively automatically adjusts the pre-existing reservation size estimate. The estimate may slowly shrink if no overflows are encountered but may quickly grow if an overflow is detected.

Abstract: A technique for transaction recovery by one transaction manager of another transaction manager's transactions in which each transaction manager is adapted to manage two phase commit transactional operations on transactional resources and to record commit or rollback decisions in a transaction recovery log. The recovery transaction manager detects apparent unavailability of the another transaction manager for transaction processing and initiates a transaction recovery process for the another transaction manager's transactions. This process also determines whether any of the transactions of the another transaction manager have all respective resources prepared to commit without there yet being a pending commit decision record in the another transaction manager's recovery log. If so, the recovery transaction manager writes a rollback record indicating an intention to roll back the identified transaction, in the another transaction manager's recovery log provided no commit decision record has been recorded.
