Intellisense randomly failing in MacOS

[dengyaotriangle]

Type: LanguageService

Describe the bug

• OS and Version: MacOS Catalina 10.15.7
• VS Code Version: 1.54.1
• C/C++ Extension Version: 1.2.2
• Other extensions you installed (and if the issue persists after disabling them): Disabled
• Does this issue involve using SSH remote to run the extension on a remote machine?: No

Trying to edit any code cause the language provider to fail.

[2021-03-10 23:33:00.726] [exthost] [error] [ms-vscode.cpptools] provider FAILED
[2021-03-10 23:33:00.726] [exthost] [error] undefined
[2021-03-10 23:33:48.726] [exthost] [error] [ms-vscode.cpptools] provider FAILED

[2021-03-10 23:33:49.966] [exthost] [error] undefined

In some cases, the extension still works fine after the error. But sometimes stuck and stop to function. The latter case happen more often with computer with weaker performance or when the system is under load.

Developing UE4 and the "Pawn.cpp" is a generated headerfile with 24 includes that likely cascade.

When looking up a symbol for the first time I see cpptools-srv CPU spike and this:

@dengyaotriangle The logging

[2021-03-10 23:33:00.726] [exthost] [error] [ms-vscode.cpptools] provider FAILED

is normal and doesn't indicate a failure. I don't see any failure occurring in your logging. What is the failure you are seeing? If you're seeing it get stuck we may need more repro info, such as a call stack (https://github.com/microsoft/vscode-cpptools/wiki/Attaching-debugger-to-cpptools-or-cpptools%E2%80%90srv) or performance logs (https://github.com/microsoft/vscode-cpptools/wiki/Troubleshooting-Performance-Issues).

@magwa101 Your issue seems unrelated. Can you file a new issue with more repro details? What does "looking up a symbol" mean exactly? Is the cpptool-srv process restarting due to memory usage, e.g. you can try increasing C_Cpp.intelliSenseMemoryLimit?

[magwa101]

Ok, got it.

Your PCH some logic has issues. I have 2 files PawnTank.h and PawnTank.cpp. If in PawnTank.ccp when I do a look up (hover with with left mouse button held down) cpptools.srv goes up as high as 2GB Real Mem then generates a 1.7GB PCH cache file for PawnTank.h. This takes about 50 seconds. If I close PawnTank.cpp, then reopen it, the whole process takes another 60 seconds as PawnTank.h PCH is regenerated unnecessarily yet again.

You're building a huge in memory cache structure, then dumping it when the file is closed. I recommend some sort've memory mapped DB that is local plus better cache invalidation logic.

The UE4 tutorial "Toon Tanks" is here https://gitlab.com/GameDevTV/UnrealCourse/ToonTanks. Install UE4, clone "Toon Tanks", build and step around, you'll see.

I didn't want this to be a career move so I'm going to live with what I've got.

I switched C_Cpp Tag Parser and for the time being, it works like a charm.

It‘s spitting out "error" messages so I mistakenly assumed that they are related. It does not get stuck too often. When it got stuck, the intellisense info does not get updated. Here's a screenshot.

I've changed the code but the error information still shows the error before the change.

the process cpptools-srv have 0% cpu usages after it got stuck.

It is maybe same as #7118. But I do not know the steps to reproduce. It randomly happens while editing code normally.

[sean-mcmanus]

@dengyaotriangle Yes, if you're seeing errors not updating after editing, that would be the same as #7118 . Unfortunately, we're not sure yet how to fix that yet and/or how to more reliably repro the issue. I debugged it when I was reproed it one time and saw it was in a state where it mistakenly thought it was in the middle of an update so it was aborting the valid update request, but I don't know how it got into that state. I think we need to find some better repro steps.
