Details
Get up-to-speed with the latest Linux Qt debugging and performance tools
This training gives an introduction to various tools which help developers and testers in finding bugs and performance issues.
The tools presented cover a wide range of problems, from general purpose debugging and CPU profiling to Linux specific high-level analyzers. Often, it is relatively simple to run a tool, but interpreting the results, or even just using some of the more advanced tools, requires deep technical knowledge.
Table of contents
Debugging on Linux:
- a debugger that allows to go back in time: RR
- tracing: strace
- memory error detectors: AddressSanitizers
- thread error detectors: ThreadSanitizer
- GammaRay to investigate internals of Qt applications
Profiling on Linux:
- CPU: Linux perf, hotspot
- memory usage: heaptrack
Prerequisite
Knowledge and experience programming with Qt and C++. Basic understanding of multithreaded programming.
We will cover what I consider the most essential debugging and profiling tools on Linux. I'll show you how to use the tools, how to interpret the results. We will talk about problems you may run into during setup. And we will discuss optimizations for certain types of code patterns.
Topics include:
- sanitizers ASAN/UBSAN/TSAN
- linux perf, hotspot
- heaptrack
