Extension crashing in WSL

[daimor]

What it's going on, how to make it working? IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2022.1.1 (Build 374U) Tue Oct 18 2022 17:51:36 EDT Switched on trace, but nothing useful there

Looks like it happening not for every class, only one particular

[Error - 2:39:06 PM] The InterSystems Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information.

And why issue with just one file, affects the whole extension. If it caught something that it can't process just die, and does not work anymore, until reload

[daimor]

Managed to get minimal reproducible class, the issue in © in description

/// ©
Class User.crash

}

Hi @daimor, if you roll back to version 2.4.4 does the issue persist? I couldn't reproduce this on my Mac or PC, but I don't have WSL set up.

[daimor]

Installed 2.4.4, no difference also crashed

[daimor]

Looks like it's happening on any unicode symbol anywhere in the code

@daimor Something similar was reported in #298. Could changing locales fix your issue? If not and VS Code pulled the right extension version (should be the linux-x64 version based on your output) I can try to reproduce this.

[daimor]

locale is UTF8, no idea which locale to change, I used russian language as an example, I see no reason that it should crash on whatever locale is set anyway I discovered it for sign © which is not language specific the codebase I'm working on should be in English only anyway

[isc-bsaviano]

@daimor I upgraded my WSL2 distribution to 22.04 and node to 20 and then tried to reproduce this issue but I couldn't. Here's my terminal output. I used the current version of linux-x64-isclexer.node found in GitHub.

Reproduced in docker

docker run -v .:/demo -w /demo node:20 bug.js

[isc-bsaviano]

Is that container running in Docker on WSL or Docker Desktop on windows? Also, what's the base OS of that image, Alpine or some other Linux?

[daimor]

Docker on WSL this one is not alpine, with alpine isclexer does not work

[isc-bsaviano]

I was able to reproduce this with the node:20 container image on WSL and using Docker Desktop on my mac. Looks like the image uses Debian and not Ubuntu. I think our Linux binaries are built on Ubuntu. I wonder if that could be a cause.
