debugging

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

问题 I'm updating a package from python 2 to 3 and I cannot get imports to work. Even the easy ones like import math or import os. Everything checks out ok when I run it with idle. If I try to run it through terminal I get a failed to load process message. In debugger it runs through a few file paths and always gives the same error. I've read a lot of documentation on imports and I'm fairly certain the imports are correct. import os ... import logging ... ... import argparse log = logging

问题 I use Netbeans on my windows desktop to debug a PHP web application remotely running on a Linux server with xdebug installed. One missing feature that constantly bothers me is: I can not view the content of static variables in a class. Often I have to resort to the "print" or "var_dump" method to find the variable content, which is very inconvenient. Does anyone know how to config it properly? I failed to find any related settings in the Netbeans menu. My Netbeans version is 7.0.1 running on

问题 If I have a line like this: var.getSomething().getSomethingElse().setNewValue(stuff.getValue().getWhatever()); If that line creates a NullPointerException , is there any way of finding out which method is returning a null value? I believe I was able to split the line at every dot and get the exception showing which line was failing. But I can't get that to work anymore (maybe I remember incorrectly). Is the only good debugging possibility to write it like this? a = var.getSomething(); b = a

问题 I am having troubles with a Linux kernel panic which I need to investigate further. When it happens, the kernel panic output always goes to the display adapter only and is shown on the monitor. I need to have the kernel panic output to a serial USB console, not only on the display adapter. In the situation where the panic happens there is no monitor available. I have a serial USB console working, can log in from there and I also see some kernel messages there sometimes. However when I provoke

问题 I'm calling through php a vb6 .dll (IIS) and on some rare and weird occasions when i call a particular function the php-cgi.exe crashes with message: the instruction 0x029b7387 referenced memory at "0x0f138000". The memory could not be written. Click OK to terminate, click cancel to debug the memory address might slightly change but always ends in 8000. Is there any way to debug and find out what is wrong with my .dll ? thanks in advance. 来源： https://stackoverflow.com/questions/14502834/debug

问题 If I wrote: IList<Video> videoContainer = videos.ToList(); DateTime theData = videoContainer.First().YouTubeEntry.Published; the code works perfectly. But if I go in Debug mode and I analyze videoContainer expanding the fields, I can't see that field Published . Why? 回答1: It works a lot easier when you grab the item of interest first IList<Video> videoContainer = videos.ToList(); var entry = videoContainer.First().YouTubeEntry; // debug 'entry' DateTime theData = entry.Published; 回答2: Just a

问题 I recently upgraded Keycloak to version 9, and when running in Docker, I'm having trouble attaching a remote debugger. I suspect this has to do with Keycloak's underlying upgrade to Java 9+. The error I get is: handshake failed - connection prematurally closed I have my ports mapped correctly within Docker (I can run Keycloak version 7 and it attaches just fine). 回答1: As it turns out, Java 9 introduced a security enhancement with respect to debugging.

问题 How do you print FPU registers using lldb? In gdb, you would do something like p $st0 , however doing the same in lldb results in the error: error: use of undeclared identifier '$st0' . register read st0 doesn't work either and gives the error error: Invalid register name 'st0'. . 回答1: By using register read --all as suggested by paulsm4 , I found that the name of the registers are actually stmm0 to stmm7 and not st0 to st7 . So doing register read stmm0 --format b will get you the binary
