Use Kotlin 1.3

[vietj]

Kotlin 1.3 was recently released, it should be used in Vert.x 3.6 release.

[vietj]

@gmariotti interested to tackle this ?

[gmariotti]

that was my goal after reopening the previous MR 😂. More than happy to help there

Just putting this here for future reference:

https://github.com/Kotlin/kotlinx.coroutines/blob/master/COMPATIBILITY.md

We will have to think carefully about whether upgrading to stable coroutines will break backwards compatibility (I haven't really looked too hard at this).

[dualscyther]

@gmariotti are you working on this? I'd also be keen to help out. It might be a good time to make API improvements too since we're likely to break the API anyway given our upgrade to new coroutines with the structured concurrency model.

[gmariotti]

@dualscyther not yet. I'd like to have #89 in first so that all the deprecated coroutines code is removed and then starting the migration. I quickly tried on my machine and the coroutines migration is quite simple the moment all the deprecated code is removed.

[gmariotti]

@vietj you should announce the completed migration to Kotlin 1.3 and coroutines 1.0 on the Kotlin Slack workspace

[vietj]

yes, are you present on that space ?

[gmariotti]

Yes, should I post something there? I can also share a tweet from you in some of the main channels

[vietj]

I've posted there

[vietj]

do the most noise you can :-)
