Sending multiple codeLens requests from VSCode

[kenkangxgwe]

Issue Type: Bug

I am developing a language extension but it receives multiple (two or more) codeLens requests from VSCode whenever a file is opened or changed.

After I disabled Live Share extension the codeLens went back to normal. Once a time.
Actually, I just installed the Live Share extension, but did not even run any session with it. So I guess the Live Share somehow duplicates the request.

Here is the log that shows the editor sending 3 requests with the same textDocument URI simultaneously. The textDocument was not changed during this short time.

[Trace - 1:13:20 AM] Sending request 'textDocument/codeLens - (3)'.
Params: {
    "textDocument": {
        "uri": "file:///d%3A/Projects/lsp-wl/repo/src/WolframLanguageServer/Server.wl"
    }
}


[Trace - 1:13:20 AM] Sending request 'textDocument/codeLens - (4)'.
Params: {
    "textDocument": {
        "uri": "file:///d%3A/Projects/lsp-wl/repo/src/WolframLanguageServer/Server.wl"
    }
}

@daytonellwanger Is this by design?

[daytonellwanger]

This is not by design, and quite unexpected to be happening outside of a Live Share session. Outside of a Live Share session, Live Share shouldn't be modifying the behavior of the IDE in any way.

@kenkangxgwe could you provide a minimal extension that repros the problem?

[kenkangxgwe]

Sure, just use the above commit kenkangxgwe/vscode-extension-samples@097b16b, modified from official samples.
In debug window, change the message level to verbose and open a plaintext file you will see two codeLens requests at the same time.

Any updates?

I am running into this too. Getting multiple codelens requests for one document change even when there is no live share session going. Disabling live share fixes the problem.

I'm going to close this as #4470 will address the issue of Live Share activating when not in use.
