Systems and methods are described for capturing and utilizing specific module dependency information. A hierarchical model can be created to arrange the components an existing software system in a particular hierarchy. The model defines a priority of dependencies among the components. A tool is provided for analyzing each class file of the system for references to other class files and determining, for each said class file, whether each reference is acceptable according to the hierarchical model. Once the class files and references have been analyzed, a surrogate class file can be automatically generated for the references that are determined to be unacceptable according to the hierarchical model. This process can utilize white lists and black lists associated with the class files, where the white lists specify modules to which references are acceptable and the black lists specify modules to which references are unacceptable.

Methods for detecting inter-module dependencies involve receiving by a software configuration control system check-in for each of a plurality of software components accompanied by check-in information consisting at least in part of defect information, which is utilized to identify coupling between any of the checked-in software components that were checked in together on a same defect and any of the checked-in software components that were checked in on a defect that was introduced by a defect in another software component. Warnings and reports are generated of a likely incidence of coupling between any of the software components identified as having been checked in together on a same defect, as well as between any of the software components identified as having been checked in on a defect that was introduced by a defect in another software component and such other software component.

Embodiments of the present invention address deficiencies of the art in respect to module dependency loading in an Ajax environment, and provide a novel and non-obvious method, system and computer program product for the optimized downloading of Javascript in a component based architecture. In an embodiment of the invention, a method for optimized downloading of scripts in a component-based architecture can be provided. The method can include identifying a set of module dependencies for a script embedded in a page received for rendering, locating the module dependencies in a dependency graph for the script, determining from the dependency graph a subset of the module dependencies that have yet to be loaded for the page, requesting each module in the subset in a single request, and loading each requested module in conjunction with rendering the page.

This disclosure proposes a software defect prediction method based on the module dependency graph, which identifies the defect information of the software module according to the version information of the software to be analyzed; establishes the software module dependency graph according to the dependency relationship between the software modules, and uses the developer as a Nodes in the module dependency graph; extracting internal features of the software module, extracting the dependency features of each node in the software module dependency graph by means of network representation learning, and forming a metric tuple with the internal features and the dependency features between the modules, Establish the historical defect library of the software according to the measurement tuple and the defect information of the module; use the historical defect library to train the defect prediction model for subsequent software defect prediction, and the defect prediction adopts the dynamic selection of classifiers based on local optimum The model automatically optimizes the parameters of the defect prediction model, and uses the result of the software module defect prediction model as the defect prediction result of the software to be analyzed. This method can improve the flexibility of constructing network node metrics and improve the effect of software defect prediction.

The invention discloses a function freezing / defreezing method in the automatically switched optical network. The method comprises: (1) the control node detects the freezing parameter in the freezing command, to determine the freezing type is freezing or defreezing; (2) to judge whether the freezing module parameter is contained in the freezing command; if the freezing module parameter is not contained, enter Step (3), otherwise enter Step (4); (3) to freeze / defreeze the whole control node according to the freezing type, and the process is finished; (4) to freeze / defreeze the corresponding module and the module in the previous layer according to the freezing type, the freezing module and the module dependency relationship table, and the process is finished. The adoption of the invention can realize the freezing / defreezing of the whole function of partial function of the control node; when the freezing / defreezing is performed during the normal running of the system, the whole system function can't be influenced; the adoption of the divided function freezing strategy, the freezing module can be expanded at the proper time, the impact of the whole node freezing to the systemis released, and the flexibility is enhanced.

Aiming at the clustering problem of software modules in software system reconfiguration, the invention discloses a software module clustering method for probability selection. This method first extracts the module dependency graph of the software system from the source program of the software system, and then proceeds from the sparse points in the graph to perform local merge operations on the nodes based on probability selection to obtain the preliminary module clustering of the software system. The number of connections between modules dynamically adjusts the clustering of each node based on the probability to obtain the clustering results of the software modules. The invention provides a simple, fast convergence and good clustering effect engineering method for the software module clustering problem, which is used for reconfiguring the software system structure and improving the comprehensibility of the software system.
