debugging

问题 Is there a way for an eclipse plugin to get a notification when user clicks on the "Terminate Debug" button? 回答1: You can call DebugPlugin.getDefault().addDebugEventListener(listener); to set up an IDebugEventSetListener . The DebugEvent passed to the handleDebugEvents method of the listener has TERMINATE as one of the event kinds. For example this handler is from the Ant plugin: @Override public void handleDebugEvents(DebugEvent[] events) { for (int i = 0; i < events.length; i++) {

问题 I'm using Visual Studio 2017 Version 15.9.6 on Win10 When I try to debug my application with break points, I see "The breakpoint will not be hit. No symbols have been loaded for this document.". I checked Debug > Windows > Modules and found "Binary was not built with debug information.". This is only the case for my application, all references and system DLL's are loaded. I have ensured "Debug Info" is set to Full. I have tried deleting my Bin and Obj folder and rebuilding. My profile is set

问题 I am having difficulty understanding this heroku stack trace. My app has been running very well both locally and in Heroku for a few years now. Yet I am suddenly plagued by immediate crashes on Heroku. Here is the stack trace: 2019-05-14T14:05:14.947049+00:00 heroku[web.1]: Starting process with command `yarn run server` 2019-05-14T14:05:17.599376+00:00 app[web.1]: yarn run v1.16.0 2019-05-14T14:05:17.680344+00:00 app[web.1]: $ babel-node src/server.js 2019-05-14T14:05:20.674637+00:00 app[web

问题 I've written a python script that I am attaching to a watchpoint in LLDB, such as: def wpCallback(frame, wp, internal_dict): ... and I am attaching the callback with: watchpoint command add -F commands.wpCallback watchpointID I would like execution of the program to immediately resume after wpCallback is finished. Currently, execution halts as the watchpoint normally would. Is it possible to silently continue after the function is done? Based on this answer it seems like you can do something

问题 URL in question: https://www.halleonard.com/viewpressreleasedetail.action?releaseid=10261 When you view the source in a browser and in Developer Tools, you can see all of the meta tags for Open Graph and Twitter. I have checked the Facebook Debugger and, aside from a few canonical issues, I'm fairly happy with the results. I also plugged the above URL into a third-party Open Graph Debugger: http://debug.iframely.com/ and all of the tags for Open Graph, Twitter and even other all come back

问题 I just started to learn React and I am trying to figure out how to find a specific value I am looking for. Just like you have the each.do method in Ruby and you can iterate through an array, I'm trying to do that with React. class Gallery extends React.Component { render () { // debugger; return ( <div> <img> {this.props.gallery.thumbnail_url} </img> </div> ) } } I am trying to access the thumbnail._url and when using the debugger, I am not able to access all the objects and images. I thought
