  • What is the difference between debugging and testing?

    - by persepolis
    Introduction To Software Testing (Ammann & Offutt) mentions on p.32 a 5-level testing maturity model: Level 0 There’s no difference between testing and debugging. Level 1 The purpose of testing is to show that the software works. Level 2 The purpose of testing is to show that the software doesn’t work. Level 3 The purpose of testing is not to prove anything specific, but to reduce the risk of using the software. Level 4 Testing is a mental discipline that helps all IT professionals develop higher quality software. Although they don't go into much further detail. What are the differences between debugging and testing?

  • What do you look for when debugging deadlocks?

    - by Michael K
    Recently I've been working on projects that heavily use threading. I think that I'm OK at designing them; use stateless design as much as possible, lock access to all resources that more than one thread needs, etc. My experience in functional programming has helped that immensely. However, when reading other people's thread code, I get confused. I am debugging a deadlock right now, and since the coding style and design are different from my personal style, I am having a difficult time seeing potential deadlock conditions. What do you look for when debugging deadlocks?

  • Debugging HLSL for Windows 8 application [migrated]

    - by Shervanator
    i'm currently in the process of creating a Windows 8 applicaiton using SharpDX (the managed c# directx wrapper). However I have ran into problems with one of my shaders and I want to know if its possible to debug such applications. PIX doesn't seem to work of directX apps as the executable does not like opening directly, and the new visual studio graphics debugging toolkit in VS2012 always states "unable to start the experiment" when I try to capture any information about my session. Thanks!

  • What are the most important programming skills you need to improve as a team Leader or project manager?

    - by Aba Dov
    I decided to ask this question after I read the valuable answers to the great question What is the single most effective thing you did to improve your programming skills? and after attending Ad Burns "Secrets of a rock star programmer". It made me think about me and what programming skills I try to improve. I came to realize that there should be a difference in the programming skills you try to improve as developer and the programming skills you should improve as a team leader or project manager. My question is: What are the most important programming skills you need to improve as a team Leader or project manager? What would you recommend to others that want to improve?

  • Would installing debugging symbols help for reporting bugs?

    - by Chris
    I'm running a beta version of Ubuntu (12.10) and I've been reporting crashes through apport's automated system. I've glanced at the stacktraces for a couple of the issues and noticed a lot of what look like hex addresses and these: "No symbol table info available." I was wondering if installing the debugging symbols packages from synaptic would provide better information to package maintainers when I report bugs. In other words, would the stacktrace be more useful if I installed those packages? If so, would installing those packages make any (noticeable) performances differences (will my computer run slower)? Thanks, Chris

  • Page debugging got easier in UCM 11g

    - by kyle.hatlestad
    UCM is famous for it's extra parameters you can add to the URL to do different things. You can add &IsJava=1 to get all of the local data and result set information that comes back from the idc_service. You can add &IsSoap=1 and get back a SOAP message with that information. Or &IsJson=1 will send it in JSON format. There are ones that change the display like &coreContentOnly=1 which will hide the footer and navigation on the page. In 10g, you could add &ScriptDebugTrace=1 and it would display the list of resources that were called through includes or eval functions at the bottom of the page. And it would list them in nested order so you could see the order in which they were called and which components overrode each other. But in 11g, that parameter flag no longer works. Instead, you get a much more powerful one called &IsPageDebug=1. When you add that to a page, you get a small gray tab at the bottom right-hand part of the browser window. When you click it, it will expand and let you choose several pieces of information to display. You can select 'idocscript trace' and display the nested includes you used to get with ScriptDebugTrace. You can select 'initial binder' and see the local data and result sets coming back from the service, just as you would with IsJava. But in this display, it formats the results in easy to read tables (instead of raw HDA format). Then you can get the final binder which would contain all of the local data and result sets after executing all of the includes for the display of the page (and not just from the Service call). And then a 'javascript log' for reporting on the javascript functions and times being executed on the page. Together, these new data displays make page debugging much easier in 11g. *Note: This post also applies to Universal Records Management (URM).

  • Get Rhythmbox debugging info

    - by skytreader
    I'm having a weird problem with Rhythmbox that no one else seems to have. When I pause on any audio CD, I can't get Rhythmbox to play it again. I've tried various workarounds including trying to play next/previous track, trying to manually move the seek bar, etc. but to no avail. When this happens I've no choice but to remove the CD from my drive and insert it again. There does not seem to be anything weird with my system when this happens, apart from the fact that Rhythmbox isn't playing as it is supposed to. Is there anything I can do to get more info on why Rhythmbox is acting up as such?

  • Writing Large Portions Of Code Then Debugging?

    - by The Floating Brain
    Lately I have been writing a game engine, and I have been writing a lot of "foundation stuff" (standard interfaces, modules, a message system ect.), but I have noticed a pattern, a lot of the stuff is interdependent and I can not debug until everything is done, hence I do not debug for about 3 to 5 hours at a time. I am wondering if this is an acceptable practice for this part of the project, and if not, if anyone can give me some advice? -----Update-----: I downloaded some code metrics tools, and my programs cyclomatic complexity is 1.52 which as I understand it is good, and should correlate to high cohesion, if I am wrong please correct me/

  • Remote Debugging

    - by Pemdas
    Obviously, the easiest way to solve a bug is to be able to reproduce it in house. However, sometimes that is not practical. For starters, users are often not very good at providing you with useful information. Costumer Service: "what seems to be the issue?" User: "It crashed!" To further compound that, sometimes the bug only occurs under certain environmentally conditions that can not be adequately replicated in house. With that in mind, it is important to build some sort of diagnostic framework into your product. What type of solutions have you seen or used in your experience? Logging seems to be the predominate method, which makes sense. We have a fairly sophisticated logging frame work in place with different levels of verbosity and the ability to filter on specific modules (actually we can filter down to the granularity of a single file). Error logs are placed strategically to manufacture a pretty good representation of a stack trace when an error occurs. We don't have the luxury of 10 million terabytes of disk space since I work on embedded platforms, so we have two ways of getting them off the system: a serial port and a syslog server. However, an issue we run into sometimes is actually getting the user to turn the logs on. Our current framework often requires some user interaction.

  • Developing instincts and "subconscious debugging" [closed]

    - by ggambett
    For some time now (a couple of years, perhaps?) I've noticed something that happens when I'm writing code. I write something with a syntax error, or some other subtle error. I don't really notice it on a conscious level, but I have a weird feeling about what I just wrote. I then try to compile it and I get a warning or error on the line that provoked the feeling. Lately I've been trying to pay attention to these feelings as they happen, and more often than not, I find errors right there. It's like I'm developing a subconscious debugger (or at least subconscious syntax checking ;)) I've heard of people fixing bugs in their sleep (I did a couple of times), but I don't think I've heard this kind of thing. Does it happen to someone else?

  • How to avoid “The web server process that was being debugged has been terminated by IIS”

    - by ybbest
    Problem: When debugging asp.net by attaching w3wp.exe process, you often will see encounter the following error message, the web server process that was being debugged has been terminated by IIS. Analysis: This caused Internet Information Services (IIS) to assume that the worker process had stopped responding. Therefore, IIS terminated the worker process. Solution: 1. Open IIS manager. 2.Click application Pools>>select the application pool associated with the site>>and click Advanced Settings 3. Click Advanced Settings of the application pool and set the Ping Enabled property from True to False. Now, reattach the process from Visual Studio, you should not get the error message.

  • How to fix Ogre3d segfault with std::_Rb_tree_insert_and_rebalance ?

    - by Balázs Béla
    Hello all. I'm working on a 3d music visualizer using Ogre3d, basically it's a spectrum analizer, a lot like the old xmms plugin: (http)://www.youtube.com/watch?v=_6NKBiwYN24 It works well, the bars are drawn and updated, there are no framerate issues, but it crashes randomly. Sometimes it can run without problems, finish the song, other times it crashes instantly, other times the music just stops, without a crash. Here is the source code for the main class : https://github.com/balazsbela/OgreVisualizer/blob/master/src/VisualizerApplication.cpp#L221 Also the crashes seem to happen less often when I display the framerate overlay from Ogre samples. Would limiting the framerate help ? The crashes are seemingly random. Is it a performance issue ? Please help me out, I'm quite lost on this one, I also posted on Ogre3d forums but I received no responses. (http)://www.ogre3d.org/forums/viewtopic.php?f=2&t=63207 I also tried stackoverflow: (http)://stackoverflow.com/questions/5050147/how-to-fix-ogre3d-segfault-with-std-rb-tree-insert-and-rebalance Thank you.

  • GPU Debugging with VS 11

    - by Daniel Moth
    With VS 11 Developer Preview we have invested tremendously in parallel debugging for both CPU (managed and native) and GPU debugging. I'll be doing a whole bunch of blog posts on those topics, and in this post I just wanted to get people started with GPU debugging, i.e. with debugging C++ AMP code. First I invite you to watch 6 minutes of a glimpse of the C++ AMP debugging experience though this video (ffw to minute 51:54, up until minute 59:16). Don't read the rest of this post, just go watch that video, ideally download the High Quality WMV. Summary GPU debugging essentially means debugging the lambda that you pass to the parallel_for_each call (plus any functions you call from the lambda, of course). CPU debugging means debugging all the code above and below the parallel_for_each call, i.e. all the code except the restrict(direct3d) lambda and the functions that it calls. With VS 11 you have to choose what debugger you want to use for a particular debugging session, CPU or GPU. So you can place breakpoints all over your code, then choose what debugger you want (CPU or GPU), and you'll only be able to hit breakpoints for the code type that the debugger engine understands – the remaining breakpoints will appear as unbound. If you want to hit the unbound breakpoints, you'd have to stop debugging, and start again with the other debugger. Sorry. We suck. We know. But once you are past that limitation, I think you'll find the experience truly rewarding – seriously! Switching debugger engines With the Developer Preview bits, one way to switch the debugger engine is through the project properties – see the screenshots that follow. This one is showing the CPU option selected, which is basically the default that you are all familiar with: This screenshot is showing the GPU option selected, by changing the debugger launcher (notice that this applies for both the local and remote case): You actually do not have to open the project properties just for switching the debugger engine, you can switch the selection from the toolbar in VS 11 Developer Preview too – see following screenshot (the effect is the same as if you opened the project properties and switched there) Breakpoint behavior Here are two screenshots, one showing a debugging session for CPU and the other a debugging session for GPU (notice the unbound breakpoints in each case) …and here is the GPU case (where we cannot bind the CPU breakpoints but can the GPU breakpoint, which is actually hit) Give C++ AMP debugging a try So to debug your C++ AMP code, pull down the drop down under the 'play' button to select the 'GPU C++ Direct3D Compute Debugger' menu option, then hit F5 (or the 'play' button itself). Then you can explore debugging by exploring the menus under the Debug and under the Debug->Windows menus. One way to do that exploration is through the C++ AMP debugging walkthrough on MSDN. Another way to explore the C++ AMP debugging experience, you can use the moth.cpp code file, which is what I used in my BUILD session debugger demo. Note that for my demo I was using the latest internal VS11 bits, so your experience with the Developer Preview bits won't be identical to what you saw me demonstrate, but it shouldn't be far off. Stay tuned for a lot more content on the parallel debugger in VS 11, both CPU and GPU, both managed and native. Comments about this post by Daniel Moth welcome at the original blog.

  • Vista: Improving troubleshoot approach skills

    - by Chau
    I'm not a Windows SuperUser, but neither just the regular user. I don't mind browsing the Registry, using Process Explorer, reading the Event logs, (un)installing new drivers and so on, but all this only makes me solve some problems. I tend though to run into problems where these tools aren't enough. Which tools should I learn about to improve my troubleshooting skills in Windows? Currently I'm using Windows Vista x64 (not moved to 7 yet), facing audio/video stuttering problems and I think this is a good place to improve my troubleshooting skills. I know this post is similar to this question, but my machine is only hanging occationally.

  • If my team has low skill, should I lower the skill of my code?

    - by Florian Margaine
    For example, there is a common snippet in JS to get a default value: function f(x) { x = x || 10; } This kind of snippet is not easily understood by all the members of my team, their JS level being low. Should I not use this trick then? It makes the code less readable by peers, but more readable than the following according to any JS dev: function f(x) { if (!x) { x = 10; } } Sure, if I use this trick and a colleague sees it, then they can learn something. But the case is often that they see this as "trying to be clever". So, should I lower the level of my code if my teammates have a lower level than me?

  • How to kill msvsmon.exe when finished remote debugging?

    - by dferraro
    Hi, We are a .NET LOB shop using MS CRM as our CRM platform. To this end, we many times a day during development phases are using remote debugging due to 2 connection limit to the server. We are able to setup remote debugging without logging onto the machine by using PsExec. This works great - but how the heck do we kill the remote debugger for that user, once we are finished debugging? In fact, not even sure how to kill the remote debugger in general, even when manually opening it... without remoting into server and using task manager, or keeping the server open and doing File-Exit on the debugger. Any advice?

  • 503 service unavailable when debugging PHP script in Zend Studio

    - by user25932
    I have a web server with apache 2.0 installed. It comes with Zend Server install pack. When I’m trying to debug my php files apache serves a blank page with 503 service unavailable. Of course slow server-side code is tying up Apache requests for far too long, but I need it to wait, until my debugging comes to end. When I call to the page from a browser it launches ZendStudio debugging my PHP script (request redirects Zend Debugger module). I debug through my script and if I finish debugging in 120 seconds, I normally return to the browser. When it takes more than 120 seconds the browser displays '503 service unavailable' and I can't return to page output. I have even forced 'max_execution_time = 300' 'max_input_time = 600' in php.ini and 'TimeOut = 500' in httpd.conf. No matter whether it is Opera, IE or Firefox. I spent two days googling it, no right answer until now.
