Software Disruption Patterns (Part 1)

Saturday, January 12th, 2013

These are not really testing patterns but patterns of a user or program behaviour resulting in abnormalities such as colored screens (blue and grey), crash dumps and other support artefacts including performance alerts and UI problem patterns. The first such pattern is called Space Precondition. It is often a case that a process checks for free disk space before proceeding, for example, with updates. This precondition may be violated by a user filling disk after the check but before or during installation. Such was the case with our recent Mac OS X update where we did some copying in the background while the update was downloaded that resulted in insufficient space after reboot, then a grey screen after that and subsequent disk corruption and finally reinstalling OS and loss of several hours better spent with other pattern categories.

What is a Software Narrative?

Tuesday, March 20th, 2012

The previous definition of software narratology was restricted to software traces and logs (the top left quadrant on a software narrative square, also the part of Memoretics which studies memory snapshots). Now, with the broadening of the domain of software narratology to the whole world of software narrative stories including actor interactions with software in construction requirements use cases and post-construction incidents we give another definition:

Software narrative is a representation of software events and changes of state. Software Narratology is a discipline that studies such software narratives (software narrative science).

Software Problem Description Language (Part 1)

Friday, November 11th, 2011

One of the new initiatives for 2012 is the development of SPDL (Software Problem Description Language). Its purpose is automatic generation of a software troubleshooting tool(s) based on the description of a problem. Here software problem means a post-construction problem as outlined in Introduction to Pattern-Driven Software Problem Solving. The tool construction will utilize an expanded set of DebugWare and Workaround patterns together with the refind version of RADII software development process. This will also provide necessary effectiveness, efficiency and enhanced problem solving capabilities to existing TaaS (Tools as a Service) implementations that are limited in the number of tools they offer.

I would like to thank you and recommend your training. I think that the “Accelerated Windows Memory Dump Analysis” training is a pin-point, well taught training. I think it’s the leading training in the dump analysis area and I’ve enjoyed it, the books and materials are very detailed and well written and Dmitry answered all of the needed question. In addition after the training Dmitry sent a PDF with written answers and more information about the questions that were asked. I will give this training 5/5. Thank you Dmitry.

Workaround Patterns (Part 4)

Sunday, June 26th, 2011

Sometimes Fake API calls can be an alternative to source code defect fixing especially if it provides quick problem resolution in production environment. Such faking can be implemented at binary level (as patching and hooking after link phase) or at object code level (before link phase). For the latter example please look at the following case study: Applying API Wrapper Pattern. The reverse process (introducing unexpected situations via unit testing, modeling software defects) is similar and for C and C++ can be done using Isolator++.

Just In Time Crash Analysis Report (JIT CAR)

Thursday, April 21st, 2011

Imagine a pattern-driven crash analysis report (car) when you need it: at the very moment of a crash, just in time! And the car drives you to a problem resolution. Imagine also a periodic pattern-driven just-in-time memory space analysis (JIT MSA) that provides you instant intelligent reports on what’s going on inside memory while your application, service or system is running! This is a forthcoming optional client side part of CARE (Crash Analysis Report Environment) which is being developed by Memory Dump Analysis Services engineering team under the leadership of Alexey Golikov. Combined with generative debugging techniques both client and server parts form a complete unique enterprise crash and hang analysis solution suitable for development and production environments. Stay tuned for further exciting updates.

PS. The car drives on a road to the first fault software problem solving.
