What is Debugging?

In computer programming and software development, debugging is the process of finding and resolving bugs (defects or problems that prevent proper operation) in a computer program, software, or system. Debugging tactics can involve interactive debugging, control flow analysis, unit testing, integration testing, log file analysis, monitoring at the application or system level, memory dumps and profiling. Many programming languages ​and software development tools also offer programs to help with debugging, known as debuggers.

Tools For Debugging

A debugger is a software tool that allows programmers to monitor program execution, stop it, restart it, set breakpoints, and change values ​in memory. The term debugger can also refer to the person doing the debugging. To debug electronic hardware (e.g. computer hardware) as well as low-level software (e.g. BIOS, device drivers) and firmware, instruments such as oscilloscopes, logic analyzers, or in-circuit emulators (ICE) are often used, alone or in combination. ICE can perform many software debugger tasks on low-level software and firmware.

  • Debugging tactics

May involve interactive debugging, control flow analysis, unit testing, integration testing, log file analysis, monitoring at the application or system level, memory dumps and profiling. Many programming languages ​and software development tools also offer programs to assist with debugging, known as debuggers.

  • Print debugging

(or tracing) is the act of observing (live or recorded) a trace statement, or print statement, indicating the execution flow of a process. This is sometimes called printf debugging, because of the use of the printf function in C. This type of debugging was enabled by the TRON command in the original version of the beginner-oriented BASIC programming language. TRON stands for, “Trace On.” TRON causes the line number of each BASIC command line to be printed while the program is running.

  • Remote debugging

Is the process of debugging programs running on a different system than the debugger. To initiate remote debugging, the debugger connects to the remote system via a communication link such as a local area network. The debugger can then control the execution of the program on the remote system and retrieve information about its state.

  • Post-mortem debugging

Is debugging a program after the program crashes. Related techniques often include various tracking techniques such as examining log files, issuing call stacks on crash, [9] and analyzing memory dumps (or core dumps) of corrupt processes. Process dumps can be retrieved automatically by the system (for example, when the process has been terminated due to an unhandled exception), or by instructions entered by the programmer, or manually by interactive users.

  • Algorithm “wolf fence”

Edward Gauss described this simple but very useful and now famous algorithm in a 1982 article for ACM Communications as follows: “There is one wolf in Alaska; how do you find it? First build a fence in the middle of the state, wait for the wolf to howl, determine which side the fence is on. Repeat the process only on that side, until you reach a point where you can see the wolf.” [10] This is implemented for example in the Git version control system as the git bisect command, which uses the above algorithm to determine commits which introduces a specific bug.

  • Record and replay debugging

Is a technique of creating a program execution record (e.g. using Mozilla’s free rr debugging tool; enabling debugging / reversible execution), which can be played back and debugged interactively. Useful for remote debugging and debugging of intermittent, non-deterministic defects and other defects that are difficult to reproduce.

  • Delta Debugging

technique of automating test case simplification

  • Saff Squeeze

a technique of isolating failures in tests using progressive alignment of the parts of the failed test.

  • Causality tracking

There are techniques for tracing causal chains in computing. The technique can be adapted for specific bugs, such as null pointer dereference.
