debugging

问题 I'm running a JAR with the option -Dsun.security.krb5.debug=true . How and where do I see the debug information generated? 回答1: This is a parameter for JVM. It usually goes with -Dsun.security.jgss.debug=true Afterwards, to see debug lines, perform any JGSS/Kerberos operation, for example those described in tutorial: http://docs.oracle.com/javase/7/docs/technotes/guides/security/jgss/tutorials/. Debug information is written to console. To see it you can either start jar from console java -jar

问题 I am trying to run my app which uses this GitHub project: https://github.com/PaoloCuscela/Cards/wiki/Overview But when I run my app on my iPhone 6, it crashes and gives me the error in the title. I've written 28 of these in my viewDidLoad function and the app runs fine on the simulator. let tennisCard = CardHighlight(frame: CGRect(x: 67, y: 3362, width: 250, height: 300)) tennisCard.title = "Exercise 11" tennisCard.itemTitle = "Tennis" tennisCard.backgroundColor = UIColor(red: 0/255, green:

问题 While trying to answer another question, it dawned on me that you can have code run any time in a thread when you theoretically should not have control. CPython has a settrace function for registering a tracing function in one's code. To test this idea from the use of a class, the following code was written. The problem is that tracing does not seem to occur, and no data is generated in the tracing log. What is causing the problem in the code shown below? #! /usr/bin/env python3 import atexit

问题 How to keep the browser window open after a test executes in Testcafe? There was a question on the forum here that brought me to a live Testcafe version, but it seems to be deprecated. I wish to keep the browser window open to see the elements while I'm developing the test. Update: This is my config file: { "name": "testcafe-demo", "version": "1.0.0", "description": "", "main": "index.js", "dependencies": { "testcafe": "^1.8.2" }, "devDependencies": {}, "scripts": { "test": "testcafe chrome

问题 I am trying to debug my Maya plugin that I build for Maya 2013 using Xcode 4.6.3 debugging features. I want to be able to set a breakpoint and trace through the plugin but I am not able to set Xcode up for Maya debugging. In the Edit Scheme section, I set the executable to Maya.app but that results in the following output in my Console window: Flags: -v prints the product version and cut number -batch for batch mode -prompt for interactive non-gui mode -proj [dir] look for files in the

问题 An architecture which I have to deal with is quite complicated: a native C++ Windows Service creates an out-of-process COM object (native C++, CoCreateInstance with context = CLSCTX_LOCAL_SERVER) which dynamically loads (AfxLoadLibrary) my C# DLL. I would like to debug my DLL when I click Debug -> Start Debugging. I know that I can debug it when I attach to COM object process using Debug -> Attach to process and I can use System.Diagnostics.Debugger.Launch() in my DLL code if I need to debug

问题 I have made a webpage that stores cookies to remember what ID a user has put in a scheme viewer. It works in desktop versions of IE, Firefox and Chrome. But when I try to visit it with Android or iPhone it doesn't work. What I would like to know is how you see stored cookies or how you debug JavaScript/HTML/CSS. If I look at errors in desktop Firefox I get no errors for JavaScript and CSS. 回答1: I recommend you use the remote debugger built into the chrome for android app. e.g. Start adb with

问题 I've been trying to trace a bug for 10+ hours now, and by now I'm starting to think that the bug can't be on my side. However, I have a feeling it could be me who's just forgetting or misunderstanding something. I have a class member of type std::vector called temp_materials, and inside the constructor (when temp_materials is still empty), this code runs: Material &stonewallbug = temp_materials.emplace_back(resource_lib.get_shader("DeferredGeometryShader")); stonewallbug.set_texture("texture
