C/C++ Code hints often disappear suddenly

[fm123456]

Code hints often disappear suddenly, and it will take effect only after restarting vscode. What is going on, can you help me?

[Nathaniel7687]

After cpptools updated to the version 0.28.3, I cannot use all of the features about cpptools. Also, when I run vscode, the process as shown in the picture below continues and does not end.

@fm123456 cpptools-srv might be crashing. Do you see any "failed" messages in the C/C++ Output logs?

@Nathaniel7687 The download has some issue. Can you try installing the offline vsix at https://github.com/microsoft/vscode-cpptools/releases/tag/0.28.3 ?

[Nathaniel7687]

@sean-mcmanus Even if, the vscode installed, the offline vsix cannot install the extension with the below error.

FYI, my vscode version is 1.45.1.

@Nathaniel7687 Don't double-click it -- that causes Windows to try to use the default .vsix handler of VS and not VS Code.

Instructions

To use the "offline" .vsix (that doesn't download OS-based dependencies on extension activation), download the .vsix that matches your OS and run the "Install from VSIX" command in VS Code.

@sean-mcmanus Thanks for your guidance. The problem is solved.

@sean-mcmanus hi, sean-mcmanus. How to see if cpptools-srv has crashed. the cpptools-srv is still running when code hint has uneffect

It seems that cpptools-srv has crashed，but then restarted

[sean-mcmanus]

@fm123456 Yeah, cpptools-srv will usually restart after a crash. Our next release will have some crash fixes for cpptools-srv. You could attach a debugger to cpptools-srv before the crash to get a crash call stack if you want us to identify which crash is occurring.

[fm123456]

@sean-mcmanus i find some cpptools-srv corefile, call stack are shown in the picture below

Hope it helps you~~

[sean-mcmanus]

@fm123456 This crash has already been fixed in our pending 0.29.0-insiders. This is the 1st user report of the crash though.

[fm123456]

@sean-mcmanus thanks

[sean-mcmanus]

This crash should be fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/0.29.0-insiders .
