Problems solved by technology

Because it is difficult to identify implicit file references, it is currently difficult to test the effect of file removal until the new program files are installed and the old files are actually removed from the runtime environment

[0050] According to the first embodiment of the present invention, the developer can also evaluate the effect of removing files. This is done by creating distinct layers within the multi-layer file system—including at least a back layer and an anti-file layer—and creating a corresponding The anti-file of the first file is implemented. The file system access controller can identify the distinct layers and identify matches between the first file and its inverse file. The file system access controller interprets the anti-file as an instruction to mask the existence of the first file. That is, the file system access controller can deny the existence of the first file in response to any program or data processing system attempting to access the first file through the file system access controller. When the file system access controller masks the existence of the first file, various operations can be tested on the resulting logical combination of files.

Abstract

Provided are methods, apparatus and computer program products for change management within a data processing system and in particular for simulating the effect of removal of a file from the system. An anti-file is created within a file system layer that is overlaid onto a set of computer program files. The anti-file hides a corresponding first file such that overlaying the anti-file layer on the set of program files simulates the effect of removing the first file from the set of program files.

Description

technical field [0001] The present invention provides a solution for change management in a data processing environment. In particular, the invention enables the evaluation of the effect of removing a file from a set of computer program files in a software development and testing system or a runtime data processing environment. Background technique [0002] A known technique for increasing software development is to place changes that need to be tested in file system directories that logically overlay pre-existing source code trees. Executable code can then be created from the resulting combination. The advantage of this technique is that many changes can be tested and checked out without rebuilding the entire source tree. [0003] Existing techniques provide adequate support for testing the effects of adding files or changing existing files, but little help in testing the effects of file removal. To determine the effect of removing a file requires the software developer ...
