PTAL @parlough

[AlexV525]

@parlough It's not working. :(

[parlough]

I think that's just because the test.sh script wasn't updated to handle the changes. That's why the other PR simplifies the testing.

@AlexV525 , @parlough : Is this still an active concern or fix? If so, I'd love to approve and merge soon.

It's ready on my side. Passing to @parlough. :)

@parlough : Can you make the needed changes please?

[parlough]

Yep. I discussed with Alex and I'll get back to this soon if something else I'm trying doesn't work out.

[atsansone]

@parlough : Any updates?

[parlough]

Thanks for working on this Alex and for being patient!! Sorry about the recurring delay on reviewing it and getting it landed.

We plan to remove the Docker setup from the repository, at least for now, sometime within the next few weeks. I'll have more updates soon. I'll also be making sure to spend time getting things working on Windows too.

So since this is going to be dropped since, I'll close this for now. Thanks again 💙
