documentHighlight failed when first opening a project

[Zhaoyilunnn]

Hello, thanks for the great work.

I have a small project wirtten in python. I found coc-pyright being very slow when starting. Specifically, when I first open my source file, it stucks for a long time beforing document highlighting works. Then I found the errors below. And before coc-pyright finally get to work, I found node cosuming 100% usage of a CPU core.

What's the output of :CocCommand pyright.version

[coc.nvim] coc-pyright 1.1.371 with Pyright 1.1.371

What's the output of :CocCommand workspace.showOutput Pyright

You can ignore the textDocument/documentHighlight error as the client cancelled it.

being very slow when starting

Can't reproduce this, do you have any error in :CocOpenLog?

Thanks for the quick reply.

There's no error in :CocOpenLog

It sometimes takes a long time (seconds to a minite) to highlight variables where my cursor locates, I am not sure whether this is expected behavior.

If I stay on one single source file, everything works fine after waiting for some moment (i.e., highlighting, goto definition, autocompletion, etc). However, if I do some other things like quickly switching between different tabs or use shift + G to go to the end of the source file, it somes got stuck again and I need to wait for a long time again.

As a comparison, my other coc-extensions like coc-rust-analyzer is much faster during the same period.

BTW, could you illustrate the meaning of request cancelled? I am sure I am not moving my cursor so this should not be proactively cancelled by myself, are there any other causes of request cancelled

[fannheyward]

Disable inlayHint.enable and try again, maybe same issue as #1087

are there any other causes of request cancelled

coc.nvim will cancel the request at documentHighlight.timeout, it's 300ms by default.

Thanks a lot, this do solve my problem
