WIP: initial attempt to update to scala 3.0.0-M3

[scalavision]

This is an attempt to upgrade the lib to scala 3.0.0-M3, unfortunately the compiler crash at building a typed array, at this line

https://github.com/scala-js/scala-js-dom/compare/master...scalavision:upgrade-scala3-M3?expand=1#diff-314a459d5f91479dc5debdf12f163c51278abfcee6b3503ad31dea16d07a4f61R216

I will file a bug in either scala-js or dotty (depending on where it fits best) and point to this branch. I get this compiler output:

[error] -- Error: /../scala-js-dom/src/main/scala/org/scalajs/dom/ext/Extensions.scala:219:6

[error]     |    ]#TypedArrayType
[error]     |  )
[error]     |]

Increasing the stack doesn't help.

It's a compiler crash, so it's necessarily an issue in dotty. And here apparently it's not even related to Scala.js.

Thanks , I'll report an issue in dotty then :-)

I added a bug report in dotty as suggested:

• infinite recursion in Scala.js using 3.0.0-M3 due to compiler error in dotty. scala/scala3#11064

I have a similar PR - and it seems to be green.

#446

Great! Then I'll close mine, thank you very much :-) There was a bug fixed some time ago.
