Primoz Gabrijelcic: debugging in Delphi: strategy, tools and tricks

Primoz, a Delphi developer with 30+ years of experience, walks through two different views on debugging: a high-level methodical approach for complex, hard-to-reproduce bugs, and a set of practical Delphi debugger tips and tricks, including conditional breakpoints, data breakpoints, logging strategies, and multi-program debugging.

0:00 Introduction: two views on debugging
1:37 Why most developers never really learn how to debug
2:43 Rule 1: be methodical — follow a structured process
3:25 Step 1: always reproduce the problem first
6:06 Multithreading: pausing at a breakpoint to expose race conditions
8:01 Once reproduced: test hypotheses and gather data from the program
9:04 Single stepping: never commit code without stepping through every line
11:09 Automatically capturing exceptions and crash stack traces on deploy
12:13 Proving the fix: a potential fix is not a real fix until tested
20:43 Conditional breakpoints: powerful but slow — and when to use code instead
24:48 Data breakpoints: using CPU hardware to detect memory changes
30:10 Runtime error 217: tracking down faulty init units via the System unit trick
34:59 Breakpoints as logging: writing to the Output window without changing code
39:19 GP Console: 10× faster than OutputDebugString and thread-safe
41:16 Debugging multiple programs simultaneously in Delphi
