XCode 4 (final) seems to be inconsistent. Using one argument works on the device, but fails in the simulator: -com.apple.CoreData.SQLDebug 1 Using two arguments works on the device and in the simulator: -com.apple.CoreData.SQLDebug 1
To put breakpoints in your code, double click in the left margin on the line you want execution to stop on. You may alternatively put your cursor in this line and then press Shift+Ctrl+B. To control execution use the Step Into, Step Over and Step Return buttons. They have the shortcuts F5, F6 and F7 … Read more
I would recommend you to use valgrind for linux. It will catch not freed memory, among other bugs like writing to unallocated memory. Another option is mudflap, which tells you about not freed memory too. Use -fmudflap -lmudflap options with gcc, then start your program with MUDFLAP_OPTIONS=-print-leaks ./my_program. Here’s some very simple code. It’s not … Read more
From http://www.gnu.org/s/libc/manual/html_node/Heap-Consistency-Checking.html#Heap-Consistency-Checking: Another possibility to check for and guard against bugs in the use of malloc, realloc and free is to set the environment variable MALLOC_CHECK_. When MALLOC_CHECK_ is set, a special (less efficient) implementation is used which is designed to be tolerant against simple errors, such as double calls of free with the same … Read more
Make sure you have Just My Code Enabled by going into Tools–>Options–>Debugger–>General–> Enable Just My Code. This will change your Debug–> Exceptions Dialog Box to show a CheckBox for User-unhandled Errors.

I actually found the problem. It wasn’t with JS as I thought, but with the CSS. I added class to make a CSS transition to fade in some elements. For anonymous users these elements had display: none; and probably never ran the opacity transition. The strange thing is that the transitions was on exactly two … Read more

[EDIT] From the docs at http://developer.android.com/guide/publishing/app-signing.html#setup The Android build tools provide a debug signing mode that makes it easier for you to develop and debug your application, while still meeting the … Read more
Yes. You have to spawn your process in a new port. There is a workaround to debug with clusters, in the same way you can do: Start your app with the –debug command and then: var child = require(‘child_process’); var debug = typeof v8debug === ‘object’; if (debug) { //Set an unused port number. process.execArgv.push(‘–debug=’ … Read more
It sounds like you are running out of ephemeral ports. To check, use the netstat command and look for several thousand ports in the TIME_WAIT state. On Mac OS X the default ephemeral port range is 49152 to 65535, for a total of 16384 ports. You can check this with the sysctl command: $ sysctl … Read more
