 Debugging - Wikipedia, the free encyclopedia
Some claim that the term "debugging" was first defined by Glenford J Myers in his 1976 book Software Reliability: Principles and Practices as "diagnosing the precise nature of a known error and then correcting the error".
The story goes that when one of the early computers malfunctioned, Admiral Grace Hopper discovered that the problem was that a moth had got into the circuitry and caused a short circuit.
This form of debugging is an instance of the scientific method.

There are many ways to go about debugging, such as printing out messages to the screen, using a debugger, or just thinking about the program execution and making an educated guess about the problem.
One of the primary features of this patch is that the remote host running gdb connects to the target machine (running the kernel to be debugged) during the boot process.
With Linux, the traditional method for debugging a system crash has been to analyze the details of the Oops message sent to the system console at the time of the crash.

 DebugInfo.com - Generating debug information with Visual C++
When we use a debugger to debug an application, we expect that it will allow us to step through the source code, set breakpoints in source files, inspect values of various variables, including even complex user-defined types.
For a function compiled with FPO (frame pointer omission) optimisation, debug information also stores some data that helps the debugger to determine the size of the function’s stack frame, even when the frame pointer is not available.
A side effect of using /debug linker option is the change of the default /opt:ref option to /opt:noref.

And even for debugging the Assembly code that is required during the boot process: The software that checks the Partition Table on hard disks and loads OS Boot Sectors into Memory.
DEBUG was originally designed to work with.COM programs having a maximum size of only 65,280 bytes [ (64 x 1024) - 256 ] or less; how much less, depended upon how many bytes the program needed to place on the Stack.
The subtraction of 256 bytes is necessary since DEBUG often uses the area from offset 00 through FF hex for some internal data such as the name of the file that was loaded.

 Important Information on Debug Commands  [ISDN/Channel Associated Signalling (ISDN/CAS)] - Cisco Systems
For example, if we enable debug x25 all on a box that has 200 VCs, and the output is logged to the buffer (using the no logging console and logging buffered commands), the timestamp displayed in the debug output (within the buffer) might not be the exact time when the packet passes through the interface.
When the Conditionally Triggered Debugging feature is enabled, the router generates debugging messages for packets entering or leaving the router on a specified interface; the router does not generate debugging output for packets entering or leaving through a different interface.
With ATM debugging you should explicitly specify the interface for which debugs should be enabled rather than enabling debugs on all atm interfaces and specifying a condition.

If you use methods in the Debug class to print debugging information and check your logic with assertions, you can make your code more robust without impacting the performance and code size of your shipping product.
In contrast, in Visual Studio.NET projects, Trace is enabled by default for both release and debug builds, so code is generated for all trace methods in both release and debug builds.
Note To enable debugging in C#, add the /d:DEBUG flag to the compiler command line when you compile your code, or add #define DEBUG to the top of your file.

The debug session may then call entrypoints in DBMS_DEBUG to read events that were posted from the target session and to communicate with the target session.
Without debug information it is not possible to look at or modify the values of parameters or variables.
Therefore it is the responsibility of the debug session to check and make sure that the target session has not terminated.

DEBUG stores data for its own use in those locations, so we recommend that you never overwrite bytes in that area; unless you know for sure they won't be necessary!
Example: A student in an Assembly class was told to enter a string of commands under DEBUG, the last one being: JMP 0 which he was supposed to Trace (T) to the next command and then execute it.
DEBUG uses the convention of enclosing operands which refer to Memory locations in square brackets '[ ]' (as opposed to an immediate value as an operand).

The actual memory heap of the application is by default not saved in a minidump; it is not required to debug a surprisingly high percentage of crashes.
This is to be expected; a call stack can only be walked accurately with debug information, so as you add more information, your stack will get more accurate, which will often expose additional frames that were not in the original.
In addition, the creation of minidumps from a Windows service that has an unhandled exception poses additional challenges, to do with desktop access (for example, if no one is using the console, then you cannot prompt them) and security contexts.

The idea of Debug is that you just add calls to Trace, and as far as possible, you don't need to add anything else, especially declarations.

A TraceListener class is a class that handles message output for Debug and Trace classes (located in the System.Diagnostic namespace).
So if you added both the TextWriterTraceListener and the EventLogTraceListener objects to Debug.Listeners, youll get the Assertion message sent to Visual Studios debug output window, the event viewer, and a text file (You must configure each listener via their constructor, but that is outside the scope of this example).
When the application is first started, the Debug class will check the web.config file and look to see if any TraceListeners should be added to its Listeners collection.
