Extension crashing on start after updating to latest version

[siferati]

The extension stopped working after updating to the latest version today.
Seems something related with libc?

0.26.0 would be the first time we released (and built the binaries) on GitHub Actions. My guess is the build machines provisioned for GH Actions are probably much newer. Comparing the 2 binaries, it seems like the newer one requires GLIBC_2.34 for certain symbols that before were found on 2.2.5.

Update: Looks like https://developers.redhat.com/articles/2021/12/17/why-glibc-234-removed-libpthread explains this.

"A downside of these changes is that we had to add many new GLIBC_2.34 symbol versions for existing functions."
"This new symbol version prevents applications that have been built against glibc 2.34 from launching on systems that have installed glibc 2.33 and earlier."

Looks like GH Actions has Ubuntu 20.04 which was released in 2020. Maybe we can try building on that for better compatibility.

What is your Linux distribution and version ? We should get a better idea of what versions would be losing support given this change.

I just tried using a ubuntu-20.04 runner and comparing to the previous (working) binary :

So I think this change could work! It looks like all the symbols maintained their earlier requirements.

Update: If you could try https://github.com/rgrunber/vscode-xml/releases/download/untagged-9ddcd1605a024802730f/vscode-xml-linux-x64-0.26.0-284.vsix and let me know if that fixes the issue that would be great. I created it by simply re-running the build with the following change : rgrunber@e6b6232

@rgrunber Thanks for looking into the issue!

What is your Linux distribution and version ?

I'm on Ubuntu 20.04.6 LTS

I can't open this link, it returns 404 page not found

[rgrunber]

I guess it would make sense that drafts are hidden 🤦 . I've published it in my fork. Could you try https://github.com/rgrunber/vscode-xml/releases/download/0.26.0/vscode-xml-linux-x64-0.26.0-284.vsix ?

@rgrunber Thanks, I confirmed your version works on my pc :)
