Intellisense gets slower over time

Environment

Version: 1.83.0-insider Commit: bccfade64adb249f57c8fcf03cba41609f76ce5c Date: 2023-09-15T05:34:53.161Z Electron: 25.8.1 ElectronBuildId: 23779380 Chromium: 114.0.5735.289 Node.js: 18.15.0 V8: 11.4.183.29-electron.0 OS: Linux x64 6.2.0-32-generic

Bug Summary and Steps to Reproduce

Bug Summary: This issue is similar to https://github.com/microsoft/vscode-cpptools/issues/2994. Intellisense progressively becomes slower as I work across cpp and header files. Seems like large header files are not cached properly because jumping to a definition inside a large header becomes slow after 3 or 4 attempts.

Edit: Looking at the debug logs, it seems like requests to the LSP are not handled properly when I send them too quickly. I have attached logs showing what happens when I perform the repro steps

Steps to reproduce:

  1. Open a project that uses a big header e.g. vulkan
  2. Use a class from the header
  3. repeatedly press f12 to go to definition, and then ctrl+alt+- to go back

Expected behavior: Once intellisense finishes loading, f12 should be instant Actual behaviour: After 3 or 4 attempts of going to definition, intellisense starts to become very slow

Other Extensions

The issue is still present even when cpptools is the only enabled extension.

Additional context

This behaviour also happens on windows.

Hello, I'm sorry that we missed this issue. We recently released an IntelliSense overhaul that should improve the scenario you described. Previously, we were not able to pre-empt expensive IntelliSense operations with faster commands like go to definition. This should be possible starting in the 1.19.2 pre-release. Please give it a try and let us know if your issue still persists.

no, still not working.

Ok. Thanks for the update. I'll reopen this issue.

bobbrow avatar Feb 03 '24 01:02 bobbrow

Hi @billgan1024 . When you activate a file, that initiates an IntelliSense pass on that file (even if it has not changed). This is partly a failsafe to accommodate for other causes of changes, such having edited a header used by that file since it was last active, or having edited the file in another editor. Switching between files also triggers a flurry of requests from VS Code, for things like semantic tokens and folding ranges. I believe what you've captured in your prior comment is the impact of other simultaneous operations. When there are other operations in progress, new requests may be delayed behind them. This type of work should not be slowing down IntelliSense over time, per se.

For this type of issue, getting the C/C++ log channel output (with the "C_Cpp.loggingLevel": "Debug") would be helpful to correlate what is also ongoing while you're seeing a performance issue. (I do not see any issue in the log output you provided earlier. If you can show the output simultaneously with the recording of slow operations, perhaps that can show a correlation.)

This issue has been closed because it needs more information and has not had recent activity.

This issue is a lost cause. My only request now is that Code - OSS be renamed as to stop appropriating open source values and to stop tempting people to waste their time filing issues here.

billgan1024 avatar Mar 20 '24 08:03 billgan1024

I'm sorry that this frustrates you. As your video shows, sometimes it's instant and sometimes it's not. There is a lot of complexity involved in writing a language server. We are always striving to improve all the scenarios and appreciate your feedback, but insults will be moderated per our code of conduct.

bobbrow avatar Mar 20 '24 16:03 bobbrow

With all due respect, I don’t think it’s in good taste to cry about how hard it is to maintain a language server while simultaneously keeping it locked down and proprietary.
