Language server compilation error and no syntax highlighting in vscode when code is valid on Windows

[markphillips100]

1. Minimal reproduce step (Required)

I've added a minimal repro sample here that triggers error popups in VSCode along with no syntax highlighting, even though the code is valid (I think).

It "feels" like the server has a problem with the filter statement but this could be just a false observation on my part.

Whenever the issue arises and I make some change to rectify, I always have to restart VSCode to test if the server is okay again.

2. What did you expect to see? (Required)

Syntax highlighting should work even if there is a compilation error and indicate what the error is to the user.

If I comment the code in resources/contributorAssignees.k and restart VSCode, main.k shows the following expected highlighting and no errors from language server.

3. What did you see instead (Required)

I see errors under the kcl language server output window:

[Info  - 7:47:28 PM] on did open file: AbsPathBuf("d:\\Dev\\github\\kcl-test\\main.k")
thread '<unnamed>' panicked at sema\src\core\global_state.rs:514:66:

main.k shows no coloured highlighting.

4. What is your KCL components version? (Required)

kcl --version: 0.8.6 kcl-language-server: 0.8.5 VSCode extension "KCL" by kcl_extension_publisher v0.1.6 VSCode v1.88.1 Windows 11

[Peefy]

Thank you for your feedback. There are indeed bugs in version 0.8.5 of the language server, which have been fixed. We will release version 0.8.6 later.

Closed by https://github.com/kcl-lang/kcl/pull/1247 and released kcl-language-server v0.8.6

[markphillips100]

@Peefy is this supposed to be fixed in kcl-language-server v0.8.6? I just bumped kcl to v0.8.7 and kcl-language-server to v0.8.6 and still seeing the same issue with my test repo (pull latest as I removed a file from the "language-error" branch.

[Peefy]

cc @He1pa Can you help investigate it on the Windows platform. The code repo is here. https://github.com/markphillips100/kcllsp-test

I was unable to successfully reproduce the issue.

[markphillips100]

Just FYI @Peefy @He1pa , I got hold of a macbook briefly and tried my test repo and also my real compositions repo under the same conditions. No problem on the mac so appears this may be a windows OS only thing.

[Peefy]

Thank you! @markphillips100 We will fix it soon. ❤

[Peefy]

Closed by #1283, will release kcl-language-server v0.8.7 soon.

[markphillips100]

Hi @Peefy kcl-language-server v0.8.7 appears to fix the current test repo, however my real code is still throwing errors in the language server - usual "compile failed code: -32603". Something else causing a problem now I suspect.

I'll see if I can narrow it down and update the test repo.

[Peefy]

Thank you @markphillips100 Could you please give more language server logs?

[markphillips100]

Yep. I'll copy code for one of my compositions into a new test repo, the smallest one that breaks, and reference here when available with logs attached.

[markphillips100]

@Peefy I've added branch error2 and included one of my real compositions. Note, there seems to be a separate issue in regards to some schema complaints around matchControllerRef. You'll see assuming syntax highlighting works for you. I know the code compiles and is used by function-kcl so not sure what the complaint the compiler has here. Anyway, back to the main issue...

What I've observed is that if I close any open files, close VSCode, reopen it and wait a few seconds then select main.k, syntax highlighting appears, and if I select each file in the project it'll show correct highlighting.

If I do the same but open the resources/notification.k file, or any of the files in resources actually, then the language errors start. Here's log output:

cc @He1pa Can you help investigate this issue?

[Peefy]

Closed by #1301 and release kcl-language-server v0.9.0-alpha.1

[markphillips100]

@Peefy I'll give it go tomorrow and give you feedback.

[markphillips100]

@Peefy all looks great in all my kcl composition code on windows, so thank you and @He1pa

I also fixed the issue you mentioned which falsely report error about schema config

[markphillips100]

Yes thank you. I did notice that was working now too. Great work
