Bug Summary and Steps to Reproduce

Bug Summary:

when openning a source code from remote ubuntu, it uses a long time to loading symbols, and then can not find the symbols with Ctrl+shift+O.
after loading the symbols for some time, it will lost the symbols until loading again
if I add a new function, outline can not load the function symbols
some functions can not be loaded, but I can not find the cause, may be like this code in the function: #if xxx #if xxx #endif #endif

Are you able to provide any repro code?

Also, if you set C_Cpp.loggingLevel to "Debug" do you see any "tag parsing" error messages in the C/C++ logging window?

it spends long time to load symbols (76.122), while sourceinsight can load it immediately.

Jul 14 '22 13:07 ganqiuye

The IntelliSense update time is different from "document symbols". One problem might be if the files are being accessed remotely, ideally, the files should exist on the remote Linux OS. Another issue is that the 1951 error squiggles, so it seems like IntelliSense is not configured correctly, which could contribute to slower results due to extra error handling.

Jul 14 '22 21:07 sean-mcmanus

You need to add a flag to compilerArgs to make IntelliSense target linux-clang-arm64 instead of linux-clang-x64 -- that's probably why you're getting the 1951 error squiggles. You should check what flag your compiler is using.

Jul 14 '22 21:07 sean-mcmanus

thx, I found that it looks faster when using clang-arm64， but it only works for setting first，it will change to x64 later.

my settings: tt2

Jul 15 '22 03:07 ganqiuye

And I found that OUTPUT is showing: tt3

it took a long time, which I think it's not necessary to query

Jul 15 '22 04:07 ganqiuye

Well, I can accept for loading symbols long time when opening a source file, but not for losing the symbols some time later until loading again, and that will go on and on.

Jul 15 '22 06:07 ganqiuye

We're detecting that your clang compiler builds x64 by default and there should be args you can add to compilerArgs to make it cross-compile for arm64.

What do you mean by "losing symbols"? Can you provide logging or a screenshot for that case?

Jul 15 '22 16:07 sean-mcmanus

I may have reproed the bug. It says "No symbols found in document" in the outline view.

Jul 15 '22 17:07 sean-mcmanus

The bug stopped reproing. Any idea how to get it back into the bad state?

Jul 15 '22 18:07 sean-mcmanus

hi, I have found what codes like that will cause the symbols can not be loaded:

fun1() 
{  //l_bracket0
.....
#if 1
  if (condition1) {    //l_bracket1
#else
  if (condition2) { //l_bracket2
#endif
 ....
   } //r_bracket1
} //r_bracket2

fun2()
{
}

symbol of fun2 can not be loaded, because l_bracket2 <->r_bracket1, l_bracket1 <-> r_bracket2

but l_bracket0 has none!

Actually, l_bracket1 <-> r_bracket1 l_bracket0 <-> r_bracket2

Jul 26 '22 09:07 ganqiuye

Thanks for reporting this. I've filed a bug on our shared VS parser at https://developercommunity.visualstudio.com/t/C-IntelliSense-has-no-document-symbol/10104429 .

https://github.com/microsoft/vscode-cpptools/issues/8613 and https://github.com/microsoft/vscode-cpptools/issues/3681 are related bugs, but they have different root causes.

Jul 26 '22 17:07 sean-mcmanus

Thx, now, there are 3 questions left：

when openning a source code from remote ubuntu, it uses a long time to loading symbols, and then can not find the symbols with Ctrl+shift+O.
after loading the symbols for some time, it will lost the symbols until loading again
if I add a new function, outline loads the function symbols with a long time

question 1 and 3 should be the same reasion.

And now I have set the config like this：

then, it looks faster than before，and it takes about 1 minute but not immediately, the reasion may be that:

it takes long time to traverse header files, which I don't want, I just think of vscode as an editor, not a compiler. Forgive me if I'm wrong for orientation of vscode. Thanks again

and question 2, I have also found the way to reproduce it:

open a source file(A) until loading all symbols
add（fix） some codes in a function and keep the file A openning
open another source file(B)
change to file A while file B loading the symbols

Then You will see the symbols of File A are all lost in the OUTLINE window, and saying: "Loading document symbols for FILE A"

Loading the symbols takes a minute time,

Then, if I often fix codes in files, and switch files, it will spend too much times.
