What is post mortem debugging?

What is post mortem debugging?

Post-mortem debugging involves inspecting the state of an application that has crashed or failed in some way, in order to determine the conditions that lead to the failure. Like runtime debugging, both symbolic debugging with a debugger and ad-hoc print statements are useful for analyzing an application after it fails.

What is debugging in C programming?

Debugging is a methodical process of finding and reducing the number of bugs (or defects) in a computer program, thus making it behave as originally expected.

What are various debugging techniques in C?

Effective Techniques for Debugging C & C++

• Step Into Selection. Typical run control allows you to navigate through your code with commands such as run, stop, step, etc.
• Dynamic Printf.
• Disassembly View.
• Memory View.

What are debuggers used for?

A debugger is a software tool that can help the software development process by identifying coding errors at various stages of the operating system or application development. Some debuggers will analyze a test run to see what lines of code were not executed.

How do I get rid of ProcDump as default debugger?

For more information on managing security related to folders, see Security During Postmortem Debugging. To uninstall ProcDump as the postmortem debugger, and restore the previous settings, use the -u (Uninstall) option.

What is the difference between testing and debugging?

But there are various differences between testing and debugging. Testing is the process using which we find errors and bugs. Debugging is the process using which we correct the bugs that we found during the testing process.

What are the types of debugging?

There are two types of debugging techniques: reactive debugging and preemptive debugging. Most debugging is reactive — a defect is reported in the application or an error occurs, and the developer tries to find the root cause of the error to fix it.

What is the best debugging techniques?

Debugging strategies

• Incremental and bottom-up program development.
• Instrument program to log information.
• Instrument program with assertions.
• Use debuggers.
• Backtracking.
• Binary search.
• Problem simplification.
• A scientific method: form hypotheses.

How do debuggers work?

The simplified answer is: When you put a break-point into the program, the debugger replaces your code at that point with a int3 instruction which is a software interrupt. As an effect the program is suspended and the debugger is called.

How do I stop ProcDump from running?

Automated Termination: Setting an event with the name “procdump-” is the same as typing Ctrl+C to gracefully terminate ProcDump.

What are debugging strategies?

Debugging Strategies: Backwards analysis of the problem which involves tracing the program backward from the location of failure message in order to identify the region of faulty code. A detailed study of the region is conducting to find the cause of defects.
