Method and system are provided for identifying a source file for use in debugging compiled code. The method includes referencing a compiled file for debugging and searching for potential source files of the compiled file from configured repositories. The method obtains the potential source files from the configured repositories and iterates over the obtained potential source files to compile and compare each potential source file to the compiled file. One or more matching source files are identified for use in debugging the compiled file.

Identifying a source file for use in debugging compiled code

Diagnostic information for a program execution is provided, where the program is executable in a machine having a program stack for individual program elements. At least one program element is saved from the program stack into an event buffer as the at least one program element is executed. A historical event buffer associated with at least one runtime error is loaded, and a similarity between the event buffer and the historical event buffer is determined. It is requested that at least one type of diagnostic information be provided with the execution of the program in the event buffer when the determined similarity exceeds a threshold similarity.

Diagnostic stackframe buffer

Optimizing deployment of a modular application in a runtime environment is provided. The optimizing includes: deploying application modules of the modular application, each application module having a module manifest and at least one application module having parts for execution, one or more module manifests include one or more references to parts of another application module, and parts required for execution of the application, the deploying is according to the module manifest; executing the modular application; determining that at least one deployed application module has no parts executing in the runtime environment; and adapting the module manifest so that the determined at least one deployed application module will not be deployed as part of the modular application in future deployments.

System module deployment optimization

This invention relates to a system, method, and computer program product for providing diagnostic data for execution of a program, the program executable in a virtual machine having a program stack for individual program elements, the system comprising: a historical event buffer comprising historical execution data associated with at least one runtime error; an event buffer for saving each program element from the program stack as each program element is executed and updated with a new program element in the program stack; a buffer similarity engine for determining a similarity of the event buffer with any one of the loaded historical event buffers; and a diagnostic engine for requesting diagnostic information with the execution of the program in the event buffer when the similarity of the event buffer and a loaded historical event buffer is more than a threshold similarity.
