In addition to physical and virtual memory layers, we add another abstraction, the memory layer associated with source code values. We call it declarative memory. This term is not to be confused with declarative (or explicit) memory in neuropsychology. Memory corresponding to values in source code may be linearly organized but translated to a different layout by a compiler, or different values can be translated to the same virtual memory location. For example, in Rust (which prompted us to introduce this new memory concept), the following tuple is mapped to a different memory layout:

let i: i32 = 1;
let tuple: (bool, i32, &i32) = (true, 0, &i);

0:000> dt tuples!tuple
Local var @ 0x5c3196f2f0 Type tuple$<bool,i32,ref$<i32> >
   +0x004 __0              : 1
   +0x000 __1              : 0n0
   +0x008 __2              : 0x0000005c`3196f2ec  -> 0n1

0:000> dq 0x5c3196f2f0 L2
0000005c`3196f2f0  00000001`00000000 0000005c`3196f2ec

0:000> dd 0x5c3196f2f0 L4
0000005c`3196f2f0  00000000 00000001 3196f2ec 0000005c

Another virtual memory cell reuse example is the Optimized Code (function parameter reuse) memory analysis pattern.

Whereas in trace and log analysis, where there is the Declarative Trace analysis pattern where a declarative trace statement in source code may correspond to many actual trace statements, a kind of 1 to 0..N correspondence, declarative memory is usually M to N, where M >= N.
Similar to virtual-to-physical mapping, where the amount of virtual memory is greater than the amount of physical memory, the amount of declarative memory can be greater than the amount of virtual memory.

Praise for the series:

I have been working with reversing, dumps, IAT, unpacking, etc. and I am one of the few at my workplace that like analyzing hangs and crashes. I always knew that I had more to learn. So I continuously look for more info. Many links directed me to dumpanalysis.org. Frankly speaking, its spartan/simple design made me question its seriousness. But after reading some articles, I immediately decided to order "Memory Dump Analysis Anthology". I have only read 100 pages so far. But I am stunned. It is such an amazing book. How the author refines/reconstructs the call stack, and finds useful information in the stack is incredible. I am enormously thankful for the effort that the author has put into making these books. They are very didactic even though the topic is a bit hard. It is a real treasure.

Table of Contents

In 2015, we introduced patterns-based root cause analysis methodology by adding software problem mechanisms to accompany software diagnostic problems and their analysis patterns. We also planned to start populating the new pattern catalog at that time, but due to other developments and ideas, we have postponed it until now. We also plan to include a new pattern catalog and case studies in our modeling software defects course.

Usually, an identified software diagnostic problem may have several different mechanisms, and a mechanism may contribute to several diagnostic signs and symptoms. Knowing such mechanisms helps greatly in modeling a problem, devising a debugging strategy, and proposing a code fix.

We start with the Spiking Thread memory analysis pattern, which has concrete analysis pattern variants for Windows, Linux, and macOS.

From its Stack Trace, we may identify the source code location. If the code uses some memory-intensive data structure, we may have an instance of Inefficient Container Implementation. Another mechanism to consider is Partial Breaking Functionality. The defect mechanism pattern names are provisional and may change as more patterns are added that require name revisions for generality, consistency, and perhaps just better names.

Inefficient Container Implementation is when a wrong container or flawed implementation is used for memory and CPU-bound code. For example, using a contiguous vector instead of a linked list may affect CPU resource consumption on insertions and deletions. Some containers, such as queues, may use underlying container implementations that can be replaced.

Partial Breaking Functionality is when we have a potentially infinite loop with checks for some conditions that prevent it from running forever. However, the list of such conditions is only partially implemented, leaving some conditions unchecked, which causes a real infinite loop with the detected CPU consumption.

Recently, we added a few “thermodynamic” analysis patterns to our trace and log analysis pattern catalog, such as Trace Volume, Trace Temperature, and, finally, derived from an ideal gas equation metaphor, Trace Pressure. These patterns allow us to employ a Carnot cycle metaphor for a typical analysis cycle:

Initially, we have a low temperature (low importance) for a low volume of traces.

1. During the incident, temperature (importance of traces) rises, triggering the rise in pressure.
2. The volume of collected traces increases during investigations, and the pressure may go up or down.
3. Once the problem is solved, the temperature comes down.
4. During this phase, we do a retrospective and gradually reduce the volume of traces necessary for continuous monitoring to its original volume.

Software Narratology, the science of software stories, found its successful application in software diagnostics of abnormal software behavior, especially in the pattern-oriented analysis of software logs from complex systems with millions of events, thousands of threads, hundreds of processes and modules. This is a revised and updated transcript of the Software Diagnostics Services seminar on the new application of software narratology to malware analysis.

In the past, I paid little attention to traditional performance and system behavior visualizations, for example, for time series. My own visualizations included Dia|gram graphical language for software narratives such as traces and logs and, recently, memory snapshots. My latest exposure to open-source observability and visualization tools led me to think about how to describe patterns I see in a pattern language. It is easy to communicate what I see by just sending the picture, but often, we need to compare it to the previous observations or do some symbolic processing of such information.

I decided to tailor existing rich diagnostic analysis pattern languages I developed over the last +15 years into the Language of visualizations that I simply call the Lov language, my new old love of visualizations of software behavior (no pun intended). It is not a programming language but primarily a language for description and analysis; also, it can be used for hypothesis testing and simulation with the appropriate tool support. The initial inspiration for Lov comes from two dual activities: visualization synthesis for time series data and analysis of such visualizations. For a simple initial illustration, the visualization description above of CPU consumption for all processes in the system reuses the existing Discontinuity for all PID Adjoint Threads of Activity and Blackout trace and log analysis patterns. We also see Signals for Counter Values. More Lov to come in the forthcoming months.
