debugging

问题 From what I can tell, pdb does not recognize when the source code has changed between "runs". That is, if I'm debugging, notice a bug, fix that bug, and rerun the program in pdb (i.e. without exiting pdb), pdb will not recompile the code. I'll still be debugging the old version of the code, even if pdb lists the new source code. So, does pdb not update the compiled code as the source changes? If not, is there a way to make it do so? I'd like to be able to stay in a single pdb session in order

问题 I know about the (jvm) startup options to have the jvm wait until a debugger is attached - this is not what I mean here. Is it possible from within Java code to also detect attachment of a debugger, so that I could e.g. write a "script" that is doing some stuff and then at a certain point make my app wait for the debugger? 回答1: No. The options are JVM options, and no Javacode is executed before the debugger connects. You can however let the app start, and spinloop on a getter for a variable,

问题 In Visual Studio 2010 I get an error which tells me the first 1024 bytes of a response from a WCF service when consumed, but no more. I would really like to see the entire response so I can work out what is going wrong, where can I get this info from? Is there a way of logging the full text of an error or are they all limited by the 1024 byte rule? How to View more than 1024 bytes of a wcf response when an error occurs in Visual Studio 2010? 回答1: If you are doing this in debugging mode, where

问题 Is there a method to signal a breakpoint in Java like System.Diagnostics.Debugger.Break() in C#? 回答1: yes I wanted something like this, so I implemented a pretty simple solution from my C days. This may be useful if you want a lightweight answer. public class DebugHelper { public static breakHere() { int i = 0; // Set breakpoint on this line in your IDE } } To use this method. Put a breakpoint in your code on the "int i = 0;" line. And call that method in the code you are debugging. It is a

问题 I have to write a program that reads a .txt file into the tree and then it allows to perform specific operations with it. I'm stuck on the part where I need to sort tree by names and search by name as well, any input would be awesome. So, my input file is in the format : 3800 Lee, Victor; 2.8 3000 Brown, Joanne; 4.0 So, my binary tree is in the format of: typedef struct { int id; char name[MAX_NAME_LEN]; float gpa; } STUDENT; typedef struct node { STUDENT* dataPtr; struct node* left; struct

问题 Sorry for the strange name of my question. I don't know how to look for this because I don't know how these things are called. There's a features in Visual Studio at least where you can click on the left of the code and set a starting point which is a big red dot. Then you run the program and you can trace the steps by pressing f8 or f5 (different f's really) and you see the variable values on each step etc. I find it extremely useful because I can see where an error occurs and how the

问题 I have a set of points derived from a polygon. I am testing several solution in order to obtain the minimum area or the rectangle. As benchmark I am using ArcGIS (10.1). points = [(560036.4495758876, 6362071.890493258), (560036.4495758876, 6362070.890493258), (560036.9495758876, 6362070.890493258), (560036.9495758876, 6362070.390493258), (560037.4495758876, 6362070.390493258), (560037.4495758876, 6362064.890493258), (560036.4495758876, 6362064.890493258), (560036.4495758876, 6362063.390493258

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 problem similar to one mentioned in this question. I'm trying to debug protractor tests in IntelliJ Idea. After I set configuration for Node.js and press Run all tests run properly, but after clicking Debug , I see only: "C:\Program Files (x86)\JetBrains\IntelliJ IDEA 14.0\bin\runnerw.exe" "C:\Program Files\nodejs\node.exe" --debug-brk=65500 --nolazy --debug node_modules\protractor\lib\cli.js protractor.conf.js debugger listening on port 65500 [launcher] Running 2 instances of
