debugging

问题 I'd like to experiment with using form helpers inside the Rails console, but my simple minded approach of doing extend ActionView::Helpers::FormHelper didn't work. For example, subsequently calling form_for resulted in the error NoMethodError: undefined method 'dom_class' for main:Object . Using include produces the same results. Is there an "easy" way to enable me to call form helpers from the console? I'd prefer to do this without any dependency on controller or view files, if possible. 回答1

问题 I'm using VS 2015 Update 2 with an asp.net 5 web project configured for debug mode. When I run the project with F5 to debug it and hit a break point, some variables can not be observed in the watch window even when they are in scope. Further, if I hover over such variables no value is displayed. If I use the same visual studio to create an empty web project and add a webform and place the code in the load method, the debugger works fine. That is to say, I can see the variables in the watch

问题 What I mean by "map" is that I have a "main" function which calls many other programs inside, and I want to be able to see which file runs first, second, third, etc. Basically, I want to be able to see the list and order of dependencies in this large OOP design program (which the creator did not make a UML class diagram for) to help decipher the code. Surely such a functionality must exist in popular IDE's? I'm mostly dealing with C++ and MATLAB so I'm more concerned with these two

问题 I have a 32 bit .Net 4.0 application running in a wow64 environment in a 64 bit machine. The application encountered an error and I took a dump with 32 bit taskmanager present in C:\Windows\SysWOW64\taskmgr.exe I am using a 32 bit Windebugger to analyze this dump. I loaded the following dlls. 1).loadby sos CLR 2).load mscordacwks ( from the client machine). But still I am not able to use SOS commands like !clrstack,!threads etc. I get the error: Failed to load data access DLL, 0x80004005 What

问题 I am trying to debug a dump file for an application that I wrote. I added the following symbols paths to WinDbg I assumed this would download the windows symbols necessary to debug this. I then run the following cammand in WinDbg "!analyze -v" This starts analyzing and then fails because of symbols it cannot find. When I look at C:\MyServerSymbols I see the following I would have expected to see more than just the kernelbase.dll The analyze command is complaining that it cannot find the ntdll

问题 My debugger doesn't even begin to run my code. I press F5, the debug tab opens, shows that it is loading, and after a while it says "Session-1 timed out waiting for debuggee to spawn" in a pop-up window. I'm using VS Code version 1.40.1, I have my virtual environment setup, and the debugger used to work, stopping at breakpoints and changing the color of the blue bar at the bottom of the screen. Issue appeared while messing with the open() function, but the debugger doesn't work with any file.

问题 There is the excellent Start Profiling button in the SCM portal that works perfect for CPU. Then there are some sources that refer to a Download GC Dump button: https://stackoverflow.com/a/27987593/647845 But that doesn't seem to be available anymore. Then there is the Download memory dump button. But for now I can't figure out how/if I can see the Type / Refcount / Size stastistics that I'm used too. What is the recommended way to look for memory leaks in a C# Azure Web App? 回答1: Try using
