Abstract: 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 old 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.

Abstract: A software package manager uses a distribution unit containing components for a software package and a manifest file that describes the distribution unit to manage the installation, execution, and uninstallation of software packages on a computer. Information in the manifest file pertaining to a software package is stored in a code store data structure upon installation of the package. The manifest file also contains information that permits the software package manager to resolve any software dependencies upon installation. The software package manager uses the code store data structure to locate the required components when the software is executed and to remove the components appropriately when the software is uninstalled.

Abstract: A verification module evaluates intermediate language code to verify that the code is type safe before passing the code for execution. Code that is not deemed type safe can cause execution errors, corrupt the runtime environment in which the code is executing, or cause unauthorized access to protected system resources. As such, the verification module protects a computer system from intentional or inadvertent breaches of the computer system's defenses. The verification module verifies the type safety of intermediate language code that supports significant high-level language constructs prohibited by verification modules in the prior art. One exemplary verification module verifies intermediate language code that includes one or more reference-based parameter, such as a pointer (or reference), a value class containing pointers, a RefAny parameter, or a nested pointer.

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), or other reference file available on the user's computer for purpose other than serving as a decompression aid. The pre-initialized compressor then compresses the old 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.
