debugging

问题 I have a library that will be built and published as a nuget package in release mode. However for debugging purposes it is useful to capture stacktraces at various points. Capturing a stack trace is relatively expensive, and I don't want to do it in release. However neither do I want to force everyone to replace my nuget package with the debug version when they want to debug their code. Is there a way to check if the executable that a dll is running in was compiled with debug or release? In

问题 In Firebug, //@ sourceURL can be used in a Javascript eval . We can use this technique to concatenate multiple Javascript files into a single file, and still have them show up as separate files in devtools/Firebug, like so: eval("... foo.js contents ...\n//@ sourceURL=foo.js"); eval("... bar.js contents ...\n//@ sourceURL=bar.js"); Is there a similar technique for CSS files? 回答1: In CSS the correct API is to use: /*# sourceURL=<url> */ 回答2: In the absence of a better idea, it might also be

问题 I think this question is addressed here: Python spyder debug freezes with circular importing But I didn't quite get a solution. First time using the Debugger in Python. I am using IDLE. The program runs fine otherwise, but when run through the Debugger it freezes and I have to kill the program. The problem, I have figured out, is that I import scripts that I have created, that I use mostly as databases. So it's something like this. from ownScript import array where array is just a list of

问题 I know I really shouldn't ask for bug solutions here in Stack exchange, but I'm new to C and I made a program that unrolls code and prints the code out in a .c file. The problem is that when I want to print out some lines of code, the fputs function to codeOutput crashes the program(I've debugged it this far). I've tried changing the codeOutput file from .c to .txt, but it hasn't changed anything. I know this code excerpt is not really repeatable, but I'm sure I just made a dumb mistake in

问题 When I run this code, it works for about 100 iterations of the for loop then throws this error: Error in seq.default(start.at, NROW(data), by = by) : wrong sign in 'by' argument Here is the data that I used, and here is my code... library(igraph) library(zoo) #import network data as edgelist fake.raw.data <- read.csv("fakedata.csv") fake.raw.data <- fake.raw.data[,2:3] as.matrix(fake.raw.data) #create igraph object from edglist data fgraph <- graph_from_data_frame(fake.raw.data, directed =

问题 So I'm trying to debug this source code (in Python) that I didn't write that has a GUI (Kivy in particular, and I'm trying to figure out what code/event is being triggered when I click on certain things. I try to put in breakpoints for where I think it's going to be triggered, I sometimes find that I'm wrong, and the breakpoint doesn't seem to ever be encountered for what I want. Anyone have any advice for GUI debugging, and figuring out what is being triggered by certain events, especially

问题 Can anybody explain me that very strange fenomenon ? In my VS2005 Managed C++ project file (VCPROJ) is defined: <Configuration Name="Debug|Win32" .... PreprocessorDefinitions="WIN32;_DEBUG" .... </Configuration> <Configuration Name="Release|Win32" .... PreprocessorDefinitions="WIN32;NDEBUG" .... </Configuration> Whereever I used the symbol _Debug it works perfect. For example: #ifdef _DEBUG #include "noexist.h" #endif produces an error C1083: Cannot open include file: 'noexist.h': No such

问题 I have an error message arising for watchOS code to measure heart rate in HealthKit, that is working fine in a different Xcode project. I've compared the code and they seem the same. the file is InterfaceController.swift. For the line 'self.workoutsession?.delegate = self' I get the red flag error "cannot assign value of type 'interface controller' to type HKWorkoutSessionDelegate" Any ideas? Here is the code for the function. The last para is the function with the error (The prior code is
