 [No title]
If the in-process debugger were to break on some event like a breakpoint getting hit, the entire host process would stop, including the in-process debugger, and there would be no way to resume either the debugger or the debuggee.
The process object that was returned can be called and controlled from that reference (which is fine as long as the process is running); however, many of the calls to control the process will fail because the process is not in a synchronized state.
Processes in the CLR are a new entity relative to the Active Script paradigm.

 Debugging Events (Windows)
A debugging event is an incident in the process being debugged that causes the system to notify the debugger.
Generated whenever a new process is created in a process being debugged or whenever the debugger begins debugging an already active process.
This debugging event only occurs the last time a DLL is unloaded from a process's address space (that is, when the DLL's usage count is zero).

  A Framework for Debugging Client-side, Reflective and Dynamic Web Applications
Debugging Web applications is a challenge process due to many factors including the nature the applications themselves, the nature of Run-Time Environments (RTEs), and the specific features of the languages used.
Difficult to Control: Facilitating the debugging process requires controlling the RTE in order for the developer to be able to stop execution at a certain point and be able to investigate the state of the program under execution.
This part is devoted for developing debugging techniques and methodologies realized as functions that can be augmented with the source code during the source expansion process (or their locations are identified) and then called as necessary.

Network Debugging Protocol Eric Mader RFC: 643 July 1974 NIC #30873 This document describes a proposed protocol to be used in an implementation of a PDP-11 network Bootstrap service and a cross-network debugger.
The protocol is designed for debugging processes running under an operating system which can perform some of the "lower level" debugging tasks, such as planting and removing breakpoints and single stepping.

 Capturing the Debugging Process   (Site not responding. Last check: )
Because the author already knew exactly what the bugs in the program were, he simulated the process he would use to fix the bugs.
The approach of using hypertext documents that capture the debugging process could be tested to see if they aid in teaching how to debug.

In a sense, this process is similar to that followed by experimental physicists, who try to explain natural phenomena with a theory or an equation.
Experience helps in the debugging process in two ways: first, you hone your ability to execute the previous four elements; and second, you might have seen a similar bug or just plain know more about a particular problem.
Debugging can be one of the most difficult and frustrating aspects of being a programmer, but your attitude makes a big difference.

 Microsoft IIS: Debugging Windows 2000 Web Applications
Debugging scenarios can be broadly classified under three headings: live debugging, postmortem debugging, local debugging, remote debugging, and debugging the user dump.
Remote debugging can be done either using a debugger attached to a remote process through an agent, or by running the debugger on the remote machine and sharing the command line of the debugger on the local machine.
Once you have isolated the problem at the process level, you can concentrate on the threads that were active inside that process during the 100% CPU problem and try to isolate the thread that caused the problem.

 [No title]
As their names suggest, a same-process debugger is one that executes in the same process context as the debuggee, and a separate-process debugger is one that executes as a separate process.
After the debugger fork()s a child process, the child process has to use this control messages to instruct itself to stop as soon as the exec() system call is finished so that as soon as the debuggee is loaded into the memory, it is suspended to wait for the debugger's instructions.
When reverse execution is needed, a specific process state is reconstructed by restoring the address from the saved history information incrementally, and restoring the checkpointed CPU state at the specific checkpoint, and the debuggee reexecutes forward from the reconstructed state.

 Peter's gdb Tutorial: Debugging A Running Process
Whenever GDB attaches to a running process, the process is paused so you can get a handle on what the call stack looks like.
The process halted and we were able to do everything that we would've been able to do had we started the process from within GDB.
As with debugging executables and corefiles, it's only convenient to debug processes that were started from executables with debugging information compiled into them.

 Visual Studio Tools for Applications : External Process Debugging in VSTA   (Site not responding. Last check: )
With External Process Debugging, the add-in being debugged is executed in a process separate from the host application.
This debugging process either launches a new instance of the host application and the two are connected (NDD), or it attaches to an already existing instance of the host (Alt-F11).
The add-in is then loaded in the external process and objects from the object model in the host process.

 Apache HTTPD Debugging Guide - The Apache HTTP Server Project
The child worker process we want has many more threads (a few more than you configured with the ThreadsPerChild directive.) The process name is Apache (for 1.3 and 2.0) or httpd (for 2.2).
For situations where a child process is crashing intermittently, the server must be configured and started such that it produces core dumps which can be analyzed further.
However, for security reasons, most Unix systems do not allow a setuid process to dump core, since the file contents might reveal something that is supposed to be protected in memory.

 Debugging with GDB: Running
This debugging information is stored in the object file; it describes the data type of each variable or function and the correspondence between source line numbers and addresses in the executable code.
When debugging, it can be useful to try running your program with a modified environment without having to start GDB over again.
The GDB thread debugging facility allows you to observe all threads while your program runs--but whenever GDB takes control, one thread in particular is always the focus of debugging.

 Simon Mourier's WebLog : Debugging process considered harmful
If you have put all your debugging efforts in the Visual Studio debugger, putting your application in production is like sending a spaceship towards Mars without any communication with the ship: welcome to the unknown.
In a team development mode, the time spent by one individual on debugging is simply lost for the rest of the team.
I think debugging is a total waste of time for me(don't flame me ;-), and also when I look at people when they debug.

 Java Tip 56: How to eliminate debugging problems for RMI-based applications
Debugging RMI-based programs -- a painful chore -- can be made vastly easier through the use of an in-process server mechanism that allows us to use any JDK 1.1-compatible debugger to develop RMI-based client/server code.
Debugging client/server programs using the RMI API is particularly painful, because the execution path jumps back and forth between client and server.
The same codebase can be used to run the client and server in separate processes or in a single process, merely by toggling a boolean flag in the client.

 The Evolution of Software Debugging
Software debugging is the process by which developers attempt to remove coding defects from a computer program.
This is because at each stage of the error detection process, it is difficult to determine how long it will take to find and fix an error, not to mention whether or not the defect will actually be fixed.
As stated earlier, the debugging process will be significantly improved in the near future.

 Technical Note TN2124: Mac OS X Debugging Magic
In cases where a debugging facility is documented in another place, there's a short overview of the facility and a link to the existing documentation.
The BSD subsystem implements process, memory, file, and network infrastructure, and thus is critical to all applications on Mac OS X. BSD implements a number of neat debugging facilities that you can take advantage of.
For example, the debug library is prebound at a different address from the non-debug library, so prebound programs won't be able to launch prebound, and thus will launch slower.

 Debugging In-Process   (Site not responding. Last check: )
If you will eventually be deploying an in-process component, it is suggested that you perform debugging in-process within a suitable client.
One thing to bear in mind, however, is that when running in another process the Dolphin IDE is no longer in control of its own lifetime, and so if the host executable decides to shutdown then the image may be rudely terminated without giving one an opportunity to save any pending changes.
On normal shutdown, however, you should be prompted to save the image, and if not any lost changes should be recoverable from the change log in the normal way.

 debugging process
Hi, I am trying to create a separate process that will launch python and then can be used to step through a script programmatically.
I have tried something like: (input, output) = os.popen2(cmd="python") Then I expected I could select over the two handles input and output, make sure they aren't going to block, and then be able to write python code to the interpreter and read it back.
I intend to import a module, run it in the debugger with pdb.run() and the start passing debug commands in and read the output.

Funded by $1.2 million from the National Science Foundation, Whyline— short for Workspace for Helping You Link Instructions to Numbers and Events — is designed for programmers of all kinds, from hard-core professionals to weekend Web designers.
Whyline, meanwhile, has been used only to debug programs in Alice, an academic programming language with a limited vocabulary of commands to make interactive 3-D worlds, like video games.
Despite Whyline's current limitations, "we have this new way to think about debugging tasks and I don't think there is any question we can make it better than it is today," Myers said.
