Support for GHC-8.10.3

[mouse07410]

Since 8.10.2 turned out to be a short-term update. and 8.10.3 is about to be released and become "it", HLS should support it. ;-)

[mouse07410]

Out of curiosity - do you know if GHC-8.10.3 is coming, and if so - roughly when?

[jneira]

it still has not been released

[domenkozar]

would be great to also support non-moving GC once it lands

[pepeiborra]

What needs to be done to support the non-moving GC? Do you want to enable it by default?

[domenkozar]

Probably only a flag to enable it if compiled with GHC 8.10.3+ and some testing that it works.

What needs to be done, now it has been released?

[jneira]

wait for secondary releases in package managers used by ci, chocolatey f.e. for Windows
maybe we could cut a stack.yaml using it right now

[alanz]

Ok. Can we do a release that installs for non-windows (e.g. ghcup installed), and then follow up with the rest?

Not sure how long the wait will be.

[jneira]

yeah, GitHub macos uses ghcup, Linux hvr ppa and Windows choco, circle ci stack (so it needs only a working stack.yaml)
will check them

[jneira]

I am preparing the support here: https://github.com/jneira/haskell-language-server/tree/ghc-8.10.3 but no ci provider is ready yet nor stack. You can set compiler: ghc-8.10.3 but you have to install it manually.

@jneira Thanks, I tried your ghc-8.10.3 branch, and it works :-)
BTW, should ghc-lib-8.10.3.20201220 be allowed?

[jneira]

BTW, should ghc-lib-8.10.3.20201220 be allowed?

yeah, we have to at least, try it out, thanks to note it

ghc-8.10.3 is already in chocolatey, so we only have to wait for support in github actions and stack.
