[lsp] 0.11.0 consistently crashing

[jamie-oconnell]

Bug Report

When using v0.11.0 of the lsp. I am getting consistent crashes and poor performance. Tested in both WSL and Windows. I am testing with some fairly large imported crds. Downgrading to v.0.10.8 of the lsp I have seen less frequent crashes.

1. Minimal reproduce step (Required)

Use KCL lsp inside vscode.

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

No crashes.

3. What did you see instead (Required)

kcl version v0.11.0

Does this problem occur in a specific project, or does it occur in any project? If just in some specific project, can you provide sample code?

[gagemillerlob]

I also see the LSP constantly having issues when using the vscode extension. It really degrades usability when working with the language.

[He1pa]

Can you provide some code snippets that cause the error, or some steps to reproduce it? @gagemillerlob

Same issue in JetBrains IDEs. As long as no dependencies are required all works perfectly. I added the crossplane module and the performance issues had begun. After a while (minutes not seconds) the IDE will crash or all my files are highlighted with an error:

Cannot find the module crossplane. v1.pkg_crossplane_io_v1_configuration from /home/redacted/Projects/my-model/crossplane/v1/pkg_crossplane_io_v1_configuration  (CannotFindModule)
pkgpath crossplane.v1.pkg_crossplane_io_v1_configuration not found in the program  (CannotFindModule)

...

[dependencies]
k8s = "1.31.2"
crossplane = "1.17.3"

In kcl run main.k all works perfectly but takes longer than in v0.10

Example to reproduce:

import crossplane.v1.apiextensions_crossplane_io_v1_composition as cp

compositionBase: cp.Composition = cp.Composition {
    metadata = {
        name = "dummy"
    }
    spec = cp.ApiextensionsCrossplaneIoV1CompositionSpec {
        compositeTypeRef = cp.ApiextensionsCrossplaneIoV1CompositionSpecCompositeTypeRef {
            apiVersion = "dummy"
            kind = "dummy"
        }
        mode = "Pipeline"
        pipeline = [
            cp.ApiextensionsCrossplaneIoV1CompositionSpecPipelineItems0 {
                step = "automatically-detect-ready-composed-resources"
                functionRef = cp.ApiextensionsCrossplaneIoV1CompositionSpecPipelineItems0FunctionRef {
                    name = "function-auto-ready"
                }
            }
        ]
    }
}

@debfire thank you, I will fix it as soon as possible

@debfire @He1pa
Any lead on this issue? We are trying to use LSP with crossplane and facing the same issue of constant crashes :/

I'm still not starting to migrate to kcl from cue yet, a lot because of this issue...
