A reverse patch for undoing a forward patch for obtaining a new binary image from an old binary image is generated in two parts. First a reverse index file is generated when the forward patch is created at a host or server. The reverse index file identifies regions of similarity between the old binary image and the new binary image. The reverse index file is transmitted with the forward patch to an electronic device. Second, while applying the forward patch to obtain the new binary image from the old binary image, the electronic device generates the reverse patch based upon the new binary image, the old binary image, and the reverse index file. The forward patch and reverse patch may both be incremental patches. Incremental patches are generated and applied on a sector-by-sector basis.

Systems and methods for operating upon a mobile communications device. A system and method can be used with data operations with respect to the mobile communications device's memory, wherein the memory has sectors. Data structures are used with the data operations to determine whether a sector contains valid data or to locate a record's pointer in the memory. The data structures can be used for such operations as record creation, record movement, recovery, etc.

摘要:
An incremental patch is generated as a set of delta files or sector-specific patches, intended to be applied incrementally to an old binary image. Each sector-sized patch takes into account changes to the binary image made by previous patches in the series, such that cyclic dependencies are eliminated. The sector-sized patches are generated by applying a binary difference algorithm to the then-current partially patched image, until each sector has a corresponding delta file. The order for patching sectors may be determined by selecting sectors for patching based on first overwriting those sectors making the least contribution of data to generation of the new binary image.

An “UltraLite” database development environment capable of creating a database application that is more portable across multiple devices, including ones having limited computational power, is described. The applications themselves can incorporate SQL statements and SQL cursors for use against data sources, including UltraLite databases. The UltraLite development environment generates code to process the SQL in the application. The application code and generated code are compiled and then linked with the UltraLite runtime library. The result is an UltraLite program that includes application logic and database logic together in a single program. The environment includes, at its core, an “Analyzer” which receives SQL from the pre-compiler and submits the SQL to an available database server (e.g., Sybase Adaptive Server Anywhere) for parsing and optimization. The Analyzer uses the database server's (i.e., the database server of Adaptive Server Anywhere) access plans and schema information to generate C code to execute the SQL statements. By making the footprint for an UltraLite program as small as possible, the system provides a database system with low overhead, making it easier to create an application targeting device having limited computational power.

In a computer system, a system, method and computer program product for pre-selecting a folder for a current message. The system, method and computer program product involve (a) providing a folder pre-selection cache having n configurable entries, n being a predetermined positive integer greater than one, each configurable entry being configured to include an associated pre-selection criterion for matching with the current message, and an associated folder identification for identifying an associated folder in the plurality of folders; (b) for at least one entry in the folder pre-selection cache, comparing a comparison criterion, obtained from the current message, with the associated pre-selection criterion to determine a matching entry in the folder pre-selection cache; and, (c) pre-selecting the folder identified by the associated folder identification of the matching entry when the message comparison module determines the matching entry in the folder pre-selection cache.

摘要:
A system for reducing the size of software for use in a mobile device includes a predictor module and a compression module. The predictor module is operable to apply a predicate to a plurality of software routines that are to be stored in the mobile device. The predicate identifies one or more of the software routines having a pre-determined feature indicative of a software routine that is unlikely to be executed repeatedly on the mobile device. The compression module is configured to compress the identified software routine(s) to generate a compressed software routine(s). After the plurality of software routines have been loaded to the mobile device, the mobile device decompresses the compressed software routine(s) when the compressed software routine(s) is accessed by an execution thread on the mobile device.
