visual GDB Clang/Intellisense stops working

[b.timofte]

Dear all

I have the file bellow in a Cmake project

#pragma once

#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/expressions.hpp>

namespace logging = boost::log;

typedef enum logLevels
{

} logLevels;

class LoggerClass
{
public:
LoggerClass()
{
}

void init()
{
logging::core::get()->set_filter(logging::trivial::severity >= logging::trivial::info);
}

};

 

I observe Clang intellisense go to definition randomly stops working and the code colors dissapear . Modifying the file or/annd invoking itellisense via member enumeration or autocompletion will freeze VS2017 for UP tp 1 minute . Any change in this file basically freezes down the editor

 

Any idea where is the bug ?

I attached a screenshot with the freeze for example when refactoring

Hi,

It looks like it takes VisualGDB over 30 seconds to parse the source file. It could be expected first time you parse a file with many includes (Boost would be a perfect example of that), but then VisualGDB should cache the header file contents and the subsequent operations should be much faster.

Also the refactoring should normally show the “Searching for references” window while it analyzes the source. It is by design that this window blocks the reset of the Visual Studio GUI as editing the code while it is being analyzed would lead to unpredictable results.

The last log snippet looks like VisualGDB fails to properly display a popup hint for some part of the code. It should not cause any slowdown or any other issues and can be safely ignored. If it looks like VisualGDB consistently doesn’t show a popup for some code where it should work, please let us know the repro steps and we will investigate it.
