Cabal: Release for GHC 8.6

[bgamari]

It would be great to have GHC's core libraries sorted out by mid-July at the latest (by the end of June would be better).

[23Skidoo]

I'll create a release branch next week.

[bgamari]

Thanks @23Skidoo!

[quasicomputational]

Is the next version going to be 2.4? The glob stuff is gated on 3.0, so I'll change that (+ tests, docs, etc) if it is.

[23Skidoo]

We decided to do a 2.4, yep.

[23Skidoo]

Current status: blocked by #5351 and #5395, which we want to merge first.

[quasicomputational]

I've got a bunch of PRs which are each individually smallish that I'd really like to see land before the release as well. I don't think anything is blocking these except that I'd like a second set of eyes on them before I go ahead and merge. I've put them all in the 2.4 milestone, if anyone would like a look.

[phadej]

@23Skidoo note, #5351 is cabal-install patch only (well, it adds Ord to one type in Cabal the lib, that could be merged immediately).

[hvr]

@phadej btw, the reason to wait for that PR with all those carefully crafted logical commits is to avoid cherry-picking dozens of commits manually between branches... :-)

[phadej]

@hvr, yeah whatever is simpler&easier for Mikhail

[tom-bop]

Any chance new-install will make it in?

[typedrat]

I just need someone to look over the code and ideally try it on another platform or two. Seems to work at least for me, and I feel like it could make it in.

[int-index]

Let's not forget to add new extensions, QuantifiedConstraints and StarIsType.

[quasicomputational]

I've put up #5419 for those two new extensions.

[sboosali]

@typedrat I can test it on Windows and Ubuntu. Send me the branch, and tell me if I should do anything beyond running the test sweet and installing a random package. (Like, build a package under GHC 8.6 too? Or is there an integration tests or something that covers that.)

[bgamari]

@23Skidoo, any update on the 2.4 branch?

[bgamari]

Ping.

[bgamari]

I will be pushing out the 8.6.1 beta within the next week; I would strongly prefer not to have to do any further submodule bumps (and certainly no major version bumps) after this. It would be nice to have a more-or-less ready branch by early-to-mid next week. If this isn't possible perhaps then we could instead just cut a release from the 2.2 branch.

[23Skidoo]

2.4 branch created. Sorry for the delay.

[bgamari]

Thanks @23Skidoo!

[bgamari]

How is the final release looking?

[sboosali]

(btw, for a lay person to test this out, should i just clone the branch and
use it to build a project? do i have to clean out an old dist-newstyle, or
is the Cabal version part of the package hash? i have something small with
signatures, so maybe that's relevant.)

Ping.

[23Skidoo]

@bgamari I think we can do a lib:Cabal release this week and a cabal-install one soon after.

[23Skidoo]

@sboosali It should work out of the box.

[bgamari]

@23Skidoo, right, let me know as soon as you have a commit.

[23Skidoo]

@bgamari Cabal-2.4.0.0 tagged and released on Hackage.

[bgamari]

Thanks @23Skidoo!

[23Skidoo]

@bgamari I've released Cabal-2.4.0.1 now as well, which has one important bugfix (#5569); would be nice if 8.6.1 included that version instead.
