breakpoints

问题 I want to build a simple linux kernel debugger for the x86 architecture. I first want it to set break points. I was wondering if there is a kernel api for configuring the debugger registers and if so any good documentation? If there is no kernel api for debugger registers is there any documentation on how to properly configure the registers manually(using the assembly "MOV" instruction)? 回答1: It depends on which kernel versions you would like to handle. There is an API for setting hardware

问题 I have no idea where it came from, it doesn't show up in my breakpoitns view, but every time I start my program, before it gets to my code it breaks at the beginning of FileInputStream.class It's just getting really annoying. I am using eclipse 3.4 and java 1.6. Thanks! Joshua 回答1: Did you check Why does my Eclipse project have phantom debugger breakpoints? ? More specifically the " Window > Preferences > Java > Debug : Suspend execution on uncaught exceptions " option. 回答2: I had a similar

问题 I have a method which returns a block. I want to add a breakpoint inside the block. In Xcode adding a breakpoint on a line that's inside the block causes execution to pause when the method is returned and not when the block is executed. How do I add a breakpoint inside a block? 回答1: I had the same difficulty, until I tried using Xcode 4's LLDB debugger (go to Product>Edit Scheme to turn it on). Perhaps you'll have better luck with it. 回答2: From the documentation You can set breakpoints and

问题 How can I save my breakpoints in Visual Basic 6? Are there any add-ins? For now I have MZ-Tools, but unfortunately they don't save breakpoints. 回答1: I'm not sure about third party tools, but you could always use: Debug.Assert False Just remember to remove it when you're done. 回答2: Here is a nice VB6 add-in to save breakpoints on exit. http://www.darinhiggins.com/bookmarksave-addin-for-vb6 回答3: This is what the Stop statement does, i.e. act as a persistent unconditional breakpoint. 来源： https:/

问题 I'm seeing some bizarre behaviour in PyCharm. I have a Django project where breakpoints stopped working in some files but not others. For example, all the breakpoints in my app's views.py work fine, but all the breakpoints in that same app's models.py are just ignored. I've tried the following but no joy: double-check the breakpoints are enabled removing/re-adding the breakpoints closed/re-opened the project quit & re-launch PyCharm delete my configuration and create a new one Some details:

问题 When debugging a java program in netbeans, I want the debugger to stop on the line that causes a NullPointerException so I can examine the variables there. I believe I have to use a condition on the breakpoint set at that line, but what is the syntax of the condition? thanks for the help 回答1: Go to debug > New Breakpoint (alternatively CTRL+SHIFT+F8). Change the breakpoint type to Exception in the top right hand drop down menu. Type java.lang.NullPointerException in the Exception class field.
