  • CM(3) : Service Level Agreement
  • 2004
  • Ingår i: 20TH IEEE INTERNATIONAL CONFERENCE ON SOFTWARE MAINTENANCE, PROCEEDINGS. - 0-7695-2213-0 ; s. 432-436
  • Konferensbidrag (refereegranskat)abstract
    • To be able to provide support to the customers in their daily operation, one must not only have an efficient support process, but also an agreement on the types and quality of the services to be provided Such an agreement is usually called Service Level Agreement (SLA). In this paper, we suggest an SLA model and show how it is realised within four organisations in Sweden. Our model is called CM(3) : SLA, and is part of a major model called CM(3) : SLA/OLA.

  • Integrating proprietary and open-source tool chains through horizontal interchange of XMI models
  • 2007
  • Ingår i: IEEE International Conference on Software Maintenance, 2007 : ICSM 2007. - IEEE conference proceedings. - 1-4244-1256-0 - 978-1-4244-1256-3 - 978-1-4244-1255-6 ; s. 521-522
  • Konferensbidrag (refereegranskat)abstract
    • Model driven development has several advantages over traditional development, including simplified maintenance. We demonstrate an architecture which, through model driven engineering, allows heterogeneous distributed development of components in a mechatronics application. Key to the approach is an architecture which allows automated and dynamic component integration, together with model sharing through the transformation of XMI files.

  • Simplifying maintenance by using XSLT to unlock UML models in a distributed development environment
  • 2007
  • Ingår i: IEEE International Conference on Software Maintenance, 2007 : ICSM 2007. - IEEE conference proceedings. - 1-4244-1256-0 - 978-1-4244-1256-3 - 978-1-4244-1255-6 ; s. 465-468

    • XMI is a standardized format for model interchange between tools. However, XMI-based interchange currently has one great disadvantage: an XMI file exported from one tool is unlikely to import correctly into a different tool. This makes XMI unusable for moving models around in a heterogeneous development environment, leading to increased maintenance problems. We suggest using specialized XSLT transformations to bridge between the XMI dialects of tools, and report on an industrial case study in which the technique has been successfully applied.

  • Towards Accurate Binary Correspondence using Runtime-Observed Values
  • 2016
  • Ingår i: 32nd IEEE International Conference on Software Maintenance and Evolution. - IEEE Computer Society. - 978-1-5090-3806-0 - 978-1-5090-3807-7 ; s. 438-442
  • Konferensbidrag (refereegranskat)abstract
    • Establishing binary correspondence is the process of finding corresponding pairs of program elements, e.g., functions or individual instructions, between two semantically equivalent (or nearly-equivalent) but syntactically different program binaries. The binary-correspondence problem has applications in many fields, e.g., plagiarism and clone detection, reverse engineering, and security, and has therefore received significant attention both in industry and academia. Most binary-correspondence methods used in practice today are based on static analysis of the control structure in binaries. Unfortunately, such methods are often highly sensitive to syntactic differences between binaries, and discrepancies in the control structure due to, for example, using different compilers or optimization levels often severely reduce their accuracy. Several recent works have therefore proposed using dynamic analysis and comparing runtime-observed results of computations to establish binary correspondence. In this paper, we study the discriminative power of runtime-values for matching instructions in binaries, and propose several ways to increase the accuracy of value-based analyses. By utilizing techniques from the field of information retrieval combined with dynamic data-flow analysis, we improve matching accuracy by up to 55% in our experiments.

  • A case study on regression test suite maintenance in system evolution
  • 2004
  • Ingår i: 20TH IEEE INTERNATIONAL CONFERENCE ON SOFTWARE MAINTENANCE, PROCEEDINGS. - 0-7695-2213-0 ; s. 438-442
  • Konferensbidrag (refereegranskat)abstract
    • When a system is maintained, its automated test suites must also be maintained to keep the tests up to date. Even though practice indicates that test suite maintenance can be very costly we have seen few studies considering the actual efforts for maintenance of test-ware. We conducted a case study on an evolving system with three updated versions, changed with three different change strategies. Test suites for automated unit and functional tests were used for regression testing the extended applications. With one change strategy more changes were made in the tests code than in the system that was tested, and with another strategy no changes were needed for the unit tests to work.
