摘要： A method and system for downloading software update data for installing a revised software product on a client computer minimizes the amount of update data to be transmitted over the network by downloading only those files needed to put the client computer in the state for installing the product. In the beginning of the downloading process, the client computer obtains from a setup server an initial setup package that includes a setup program and a list of files required for installing the software product. The setup program running on the client computer then determines whether some current or earlier versions of those files required for installation already exist on the client computer, and compiles a request list of files needed for updating the client computer. The client computer sends the request list to a download server, which maintains a collection of update files and patches. In response to the request list, the download server downloads updating files to the client. Depending of the availability of the requested files or other factors, the downloaded files may or may not be exactly those requested. Using the downloaded files, the setup program updates the existing files to provide the set of installation files on the client computer. The desired revised software product is then installed on the client computer.

摘要： Rather than comparing an old file with a new file to generate a set of patching instructions, and then compressing the patching instructions to generate a compact patch file for transmission to a user, a patch file is generated in a single operation. A compressor is pre-initialized in accordance with the old version of the file (e.g. in an LZ77 compressor, the history window is pre-loaded with the file). The pre-initialized compressor then compresses the new file, producing a patch file from which the new file can be generated. At the user's computer, a parallel process is performed, with the user's copy of the old file being used to pre-initialize a decompressor to which the patch file is then input. The output of the decompressor is the new file. The patch files generated and used in these processes are of significantly reduced size when compared to the prior art. Variations between copies of the old file as installed on different computers are also addressed, so that a single patch file can be applied irrespective of such variations. By so doing, the need for a multi-version patch file to handle such installation differences is eliminated, further reducing the size of the patch file when compared with prior art techniques. Such variations are addressed by “normalizing” the old file prior to application of the patch file. A temporary copy of the old file is typically made, and locations within the file at which the data may be unpredictable due to idiosyncrasies of the file's installation are changed to known or predictable values.

摘要： A data compressor uses data known to exist on a destination computer for compressing an input data stream by encoding portions of the input data stream as references to matching portions of the known data. The known data is preprocessed to better correlate with the input data stream. The preprocessing includes identifying and modifying internal references in the known data, such as relative offsets and addresses of jump and call instructions in executable code or cross references and hyperlinks in documents. The preprocessing is driven by generating a set of data that describes specific individual modifications or alternatively indicates relationships between the known data and the input data stream, such as code or data block motion, from which individual modifications can be deterministically made. This generated descriptive data is included with the compressed data stream so that identical preprocessing can be applied to the known data at the destination computer based on the generated descriptive data prior to decompression. Preprocessing the known data improves compression of the input data stream since changed internal references that interrupt matches of the input data stream to the known data can be eliminated.
摘要翻译： 数据压缩器使用已知存在于目的地计算机上的数据来压缩输入数据流，通过对输入数据流的部分进行编码作为对已知数据的匹配部分的引用。 已知的数据被预处理以更好地与输入数据流相关。 预处理包括识别和修改已知数据中的内部引用，例如可执行代码或交叉引用中的跳转和调用指令的相对偏移量和地址以及文档中的超链接。 通过生成描述特定个体修改的数据集合或者可选地指示已知数据和输入数据流之间的关系（例如代码或数据块运动）来驱动预处理，从中可以确定地进行各种修改。 该生成的描述性数据被包括在压缩数据流中，使得可以基于在解压缩之前生成的描述数据将相同的预处理应用于目的地计算机上的已知数据。 由于可以消除将中断输入数据流的匹配到已知数据的改变的内部引用，所以预处理已知数据改善了输入数据流的压缩。

摘要： Information that describes two or more content delivery solutions for a particular set of target files is received in a computing environment. The solutions are associated with a container at least portions of which can be delivered to the computing environment. The container is dynamic and has internal delta dependency. An expansion mechanism at the computing environment, upon determining that more than one of the solutions is achievable in the computing environment, selects one of the achievable solutions for implementation.

摘要： In a content delivery scheme for target files, one or more recipes for each of the target files are encoded in an index. The index uses a framework that is able to represent content delivery schemes involving static containers, dynamic containers, self-contained containers, containers that are not self-contained, containers with internal delta dependency and containers with no internal delta dependency.

摘要： A system and method for managing the installation of files on a computing device are provided. A client computing device obtains installation information identifying a version of a baseline installation component stored on the client computing device. The installation information also includes an installation component delta patch that is merged with the baseline installation component to generate an updated installation component. The updated installation component is utilized to install one or more files on the client computing device. Upon completion of the installation, the updated installation component can be deleted.

摘要： A system and method for updating one or more files on a computing device are provided. A client computing device obtains update information including an index identifying particular delta patches with specific versions of installed files. Upon selecting which of the applicable updates will be implemented, an update agent on the client computing device performs an inventory to identify which version a file to be updated is installed on the machine. The update agent selects a corresponding delta patch and transmits the request to an update service.
