• Seg Fault with malloc'd pointers

  - by anon

  I'm making a thread class to use as a wrapper for pthreads. I have a Queue class to use as a queue, but I'm having trouble with it. It seems to allocate and fill the queue struct fine, but when I try to get the data from it, it Seg. faults. http://pastebin.com/Bquqzxt0 (the printf's are for debugging, both throw seg faults) edit: the queue is stored in a dynamically allocated "struct queueset" array as a pointer to the data and an index for the data

• draw is being constantly called in my android map overlay

  - by Itsik

  I'm trying to draw a route onto my MapView. I've extended Overlay and implemented the draw() method. The route is displayed properly, although while debugging, I added a breakpoint on draw(), and noticed it is being called constantly. I only want it to be re-drawn if someone moves the map or zooms (the draw take into account these changes when drawing the route) What can cause this ?

• Ember-App-Kit: How to execute code only in release mode?

  - by Dominik Schmidt

  I have created an error handler as described here: http://emberjs.com/guides/understanding-ember/debugging/#toc_implement-a-code-ember-onerror-code-hook-to-log-all-errors-in-production But this code is not only executed in production mode but also in normal debug builds which floods my server logs. I know that Ember.debug() calls and alike are being filtered out for production builds, but I couldn't find out where/how that is implemented and if that same mechanism could be used to make my code only fire in production code.

• MSSQL using SSH-tunnel from Visual Studio

  - by pbt

  Hi, I recently contacted a web host regarding support for external database access to a Microsoft SQL Database included in a package they offer. They replied saying that it is only possible with an SSH-tunnel. Is it possible to connect to a MS SQL database in Visual Studio using an SSH-tunnel? It is important for me to be able to access the database from my local machine (for debugging, generating LINQ classes, editing tables, etc). Or, how should I go about working with their database?

• How to determine at runtime hen your C++ application has the visual studio debugger attached?

  - by Jeremy Bell

  How do you determine at runtime whether the visual studio debugger is attached to your process. I've seen instructions for how to do this in .NET, but my process is a native C++ process. Support for detecting Just-in-time debugging would be nice but not a strict requirement.

• How can I get the assembly last modified date?

  - by Juan Manuel Formoso

  I want to render (for internal debugging/info) the last modified date of an assembly, so I know when was a certain website deployed. Is it possible to get it though reflection? I get the version like this, I'm looking for something similar: Assembly.GetExecutingAssembly().GetName().Version.ToString(); ie: I don't want to open the physical file, get its properties, or something like that, as I'll be rendering it in the master page, and don't want that kind of overhead.

• Cookieless Django for government site

  - by phoebebright

• What Read-eval-print-loops (REPL's) are available for C++ ?

  - by Justin Ethier

  REPL's are very useful for live debugging and experimentation. Most dynamic languages such as Ruby, Python, etc come with one built-in, however it is more difficult to build one for a statically-typed language such as C++. Despite the technical challenges, are there any REPL's available for C++?

• Spring MVC: easiest way to see incoming requests

  - by flybywire

  I am debugging a Spring MVC (3.0) app, deployed on tomcat. I want to see in my console or log files all the incoming requests. Including 404s, both generated by my app or by spring because it didn't find an appropriate controller. I'd like to see something like this: GET /index.html GET /img/logo.png GET /js/a.js GET /style/b.css POST /ajax/dothis?blah=yes POST /ajax/dothat?foo=np GET /nextpage.html ... What is the easiest way to see that.

• appengine log console extremely slow

  - by Joey

  I am using the python app engine and finding that the log console on the local development server is terribly slow. Output to this window seems to show in chunks of about 5-15 lines every second. Is that typical? I find that it's so slow that it hinders my debugging time waiting for log data to appear.

• Visual Studio Colour Settings

  - by Ian

  I've got a custom colour set in Visual Studio and one of the colours when debugging is making things a bit of a misery. Unfortunately I can't figure out which one it is, and when going through and changing all the light background ones, it still remains. Can anyone point me in the right direction? In this screenshot the current line is yellow, and the caller is the white/cream sort of colour which is the one I want to change... Thanks very much! :)

• Rails-like console for PHP?

  - by Chad Johnson

  Every so often, things work in my local PHP development environment, while in my test environment on my server, things do not. It's a nightmare to debug this. If I had a console like Rails provides, debugging would be much much simpler. Is there anything like the Rails console but for PHP? I should mention that I am using a home-brewn PHP application.

• Method parameters confusion

  - by elec

  Often time methods take more than 3 parameters which are all of the same type, eg. void mymethod (String param1, String param2, String param3) then it's very easy for the client to mix up the parameters orders, for instance inverting param1 and param2: mymethod (param2, param1, param3); ...which can be the cause of much time spent debugging what should be a trivial matter. Any tips on how to avoid this sort of mistake (apart from unit tests) ?

• Compiling in g++ for gprof

  - by myahya

  I do not understand the documentation for gprof regarding how to compile your program for profiling with gprof. In g++, is it required to compile with the -g option (debugging information) in a addition to the -pg option or not. In each case I get different results, and I would like to see where the bottlenecks in my application are in release mode, not in debug mode, where many optimizations are left out by the compiler (e.g. inlining)

• Why does this compile?

  - by akf

  I was taken aback earlier today when debugging some code to find that something like the following does not throw a compile-time exception: public Test () { HashMap map = (HashMap) getList(); } private List getList(){ return new ArrayList(); } As you can imagine, a ClassCastException is thrown at runtime, but can someone explain why the casting of a List to a HashMap is considered legal at compile time?
