Random "Failed to spawn IntelliSense process: 65520" on Mac with 1.13.3

[sean-mcmanus]

Has anyone else seen this? We're investigating....

[H-G-Hristov]

I haven't seen this error but it feels related to my previous complaint: #10090
Should it be a popup or a line in the log?
IMO: Generally 1.13.2 was better than version 1.13.3 and the earlier versions.

[sean-mcmanus]

@H-G-Hristov The error would appear in the C/C++ logging.

[sean-mcmanus]

@H-G-Hristov Also, this is the first I've heard about 1.13.3 being worse than 1.13.2. The wordexp issue is definitely fixed with 1.13.3. We don't know yet what the severity of this 65520 error is though.

[H-G-Hristov]

Well I couldn't find: Failed to spawn IntelliSense in th log and it looks like IntelliSense works but the flame is stuck there currently the hover displays: Running clang-tidy 1/2 (50%).

[sean-mcmanus]

@H-G-Hristov Is the clang-tidy process actually running? If you run code analysis on a particular file, does it queue and finish or is it stuck? It might be a bug with the status completion reporting (i.e. it might incorrectly think there's more work to do when there isn't).

[sean-mcmanus]

@H-G-Hristov Do you have the C_Cpp.codeAnalsysis.clangTidy.enabled and C_Cpp.codeAnalysis.runAutomatically both set to "true" or you are manually running it?

Yes.
Yes.I think runAutomatically is on by default.

@H-G-Hristov Is the clang-tidy process actually running? If you run code analysis on a particular file, does it queue and finish or is it stuck? It might be a bug with the status completion reporting (i.e. it might incorrectly think there's more work to do when there isn't).

Yesterday I checked activity monitor but I did't see a clang-tidy process.
I need to make some observations first to answer the questions.

What I am experiencing right now. After I start VSCode and I open a C++ file. Clang-tidy runs and displays some results. I continue working in the code editor - random stuff - editing, opining more files, and after a while I don't see the yellow squiggles anymore and the flame is stuck forever. I didn't observe such behavior in 1.13.2 I think. Before that I had a bunch of other issues which you fixed and I believe that 1.13.2 behaved overall rather reasonably.

[sean-mcmanus]

This 65520 issue happens very rarely (1 in 1000 or so?) and probably reproed with 1.13.2 as well but we didn't notice due to the lower repro probability than the other issues we were hitting and fixed. It's most likely unrelated to your issue, so we'll continue to track that code analysis issue with #10090 .
