stack-trace

问题 I want to see the stack trace in any function of my code, so i made somthing like this to call it and print the stack trace: public function PrintStackTrace() { try { throw new Error('StackTrace'); } catch (e:Error) { trace(e.getStackTrace()); } } I like to know if there are other way to do this. In some place, the Error class creates the stack trace, but maybe it didn't do it with ActionScript 3.0 so maybe it's not posible, but i want to know. Thanks! 回答1: As far as I know, the only way to

问题 For diagnostic purposes I sometimes need to store the call stack that lead to a given state transition (such as granting a lock, committing a transaction, etc.) so that when something goes wrong later I can find out who originally triggered the state transition. Currently, the only way I am aware of to retrieve the call stack looks like the following code snippet, which I consider terribly ugly: StackTraceElement[] cause; try { throw new Exception(); } catch (Exception e) { cause = e

问题 This is a weird crash I am getting. The crash happens when I press a button that goes to a certain ViewController. The line which it crashes on is: DestinationInformationViewController *info = [[DestinationInformationViewController alloc] init]; [info setModalTransitionStyle: UIModalTransitionStyleCrossDissolve]; [self presentViewController:info animated:YES completion: nil]; // CRASHES HERE [info release]; The crash trace is: *** Terminating app due to uncaught exception

问题 I'm trying to compile a project (see this SO question) using Gobo compiler and its tools and I'm getting error messages refering to standard library equal(..) . I'm sure that error is somewhere in the code I have and not in standard library but I don't know how to get some more info from geant . I'd like to know which class, function, line of code from my code invoked equal(..) or any other standard library function which might call it. And yes, I've already tried going through all equal(..)

问题 e.printStackTrace() works fine (i.e. prints my stacktrace to stderr) but Log.X fails to print a stacktrace at all. For example: } catch (IOException e) { Log.e("Network", "Exception", e); e.printStackTrace(); } Output: 08-31 03:46:21.992: W/Network(13238): Exception 08-31 03:46:22.092: W/System.err(13238): java.net.UnknownHostException: Unable to resolve host "...": No address associated with hostname 08-31 03:46:22.204: W/System.err(13238): at java.net.InetAddress.lookupHostByName

问题 Are there any possible scenarios where the Stack Trace can be completely empty? I was passed an Event Log text copied from machine Event Properties, which says the following: Description : An unhandled exception occurred and the process was terminated. Application ID : DefaultDomain Process ID : 123 Exception : System.OutOfMemoryException Message : Exception of type 'System.OutOfMemoryException' was thrown. StackTrace : For more information, see Help and Support Center at http://go.microsoft

问题 I'm getting these stack traces when running my app which crash. I get that it has to do something with "ANR keyDispatchingTimedOut".

问题 I have an error on my Android Application and one of the really annoying things that LogCat does is write exception Caused at android. at android... at android... at android... and 21 more I need to read the error inside that 21 more. Is there a way to do it? I've tried filtering the results but no luck. 回答1: You can debug the app and add a conditional breakpoint for your exception, or just a normal breakpoint if you know where it's thrown exactly. Then when you're there, you have full access
