I have a hard-to-catch error that only happend the 2 or 3 time I start my app, after a previous failure of it. But because when I do Run&Debug from the XCode menu the app is delete from the simulator or device, I can debug it to find what is happening. I try to attach to the process, but when I succed is too late and the app crash. I h...
My application has a Python interpreter embedded in it. However there's currently not any way to inspect anything about Python directly. I'd like to be able to pop up an interactive shell at various points to inspect what's going on in Python. I've found several similar questions which pointed me to code.InteractiveConsole and IPython. ...
this was the answer from the brad larson on this SO question If you add two breakpoints, you should be able to debug these exceptions. To do this, go to Run | Show | Breakpoints and create two global breakpoints (I do them globally because they are so useful in all my applications). The first should be named "objc_exception_throw" and i...

As part of my local testing process, I manually run the webdev.webserver.exe executable from a batch file. However, sometimes I would like to debug the app that runs in the ASP.NET Development Server process from within Visual Studio 2008, but I get an error whenever I try to attach to the executable: "Unable to attach to process". Doe...
I use gdb (actually DDD), and getting an element out of container is impossible. So I typically end up rolling my own loop for debugging purposes... What do you do? ...

Please suggest how I can improve in these areas in terms of: Approaches to take, where to start, and how to proceed. Tools to use, and how use them effectively. Recommended materi...
Hello, I have installed Eclipse CDT, CodeSourcery G++ toolchain on Linux host. I am using the Code Sourcery Eclipse IDE. I have installed Linux kernel using Linux Target Image Builder from the Freescale site, onto the MCF5485 board. I have created a "helloworld" project on my Linux host using the Sourcery Eclipse IDE. I have copied the ...
Hello. I'd like for debugging purposes to be able to log what functions are called and in what order. So I've been just putting Debug.WriteLine("myFunctionName(args)") all over my functions, logging it in the end to a file. Isn't there a better approach to do this? I'd hope so. ...
I've always wondered why the JVM doesn't tell you which pointer (or more precisely, which variable) is null when a NullPointerException is thrown. A line number isn't specific enough because the offending line can often contain numerous variables that could have caused the error. Is there any compiler or JVM flag that would make these ...
I'm maintaining an home-brew web-based help-desk solution and we are experiencing an erroneous change in a db field under some circumstances. The code involved is quite frankly a mess, mixing different approaches to database access (the worst and most dangerous one being building sql strings through concatenation). A full-text search of ...
Hi everybody, After learning R about 9 months ago, I am finally graduating from debugging by using print() statements every other line. I am now a pretty constant user of browser() and debug(). I have recently become aware of a few more tools: traceback(), trace(), and recover(). Does anybody have advice on when (and how) to use th...
When you change Java code while in a debugging session, Eclipse will upload the updated class files into the running JVM (hot code replace). This even works for remote applications. Is there a way to turn Hot Code Replace off (within Eclipse, not at the remote JVM)? We want to be able to debug our test and staging servers remotely, but...

I'm using TextWriterTraceListener to log diagnostics messages to a text file. However I wan't also to log a timestamp of every trace message added. Is it possible to define a kind of formatter for the listener that would automatically add timestamps? Currently I'm adding timestamps manually on every Trace.WriteLine() call but this isn't...
There are two cases where my code won't seg fault: When I use Smart::Comments in at least one place run through the debugger. I've tracked it down to this call: $action->{breakdown} = join( ' ' , each_pair { my ( $name, $length ) = @_; return "x$length" if $name eq 'FILLER'; ...
I am working on a multi-developer project and the application being developed is launcher through a launcher application which passes parameters such as the user logged in, their location, etc. Right now when I debug the application I set a breakpoint on the code that parses the input parameters and I assign the username variable my user...
Here's the scenario: I'm debugging a server process running in Eclipse 3.4.1. There are 20 threads or so, waking up at various interval after sleeping. I set a breakpoint in one method on one thread, and Eclipse stops there properly. The thread is expanded with a stack trace in the Debug view, and I can use the various buttons to st...
