Hi all,

Where does release planning happen? I'd like to start on merging some
solver-related PRs, but if there's an imminent release, that might not
be such a good idea...

Regards,

Yes, there will be a release of Cabal/cabal-install together with GHC 8.

Is it the general rule that Cabal releases are synced with GHC releases, or
can Cabal releases be more frequent?

Yes, they can, and we actually want them to. Ideally, a new
Cabal/cabal-install version would be released every six months, though
in this cycle this didn't happen.

I'd gathered as much :).

When (or where, i.e. which commit) is the branch-off point? Does anybody
know? Would it make sense to do it now-ish, or do we need to wait for
GHC 8.0rc1 or something?

Hi Mikhal

Thank you for stepping up to be the Cabal "chair".  

|  Yes, there will be a release of Cabal/cabal-install together with GHC
|  8.

Can I ask what will be in it?  Specifically, I would love to know 
what you plan concerning the issues in this snip:

| As I understand it, the idea is that for the GHC 8.0 release 
| we will also have a new Haskell Platform.  And that new HP will 
| not suffer from at least some of the flaws that have caused angst 
| in the past.
|
| The message from Mark and Michael is attached, but it dates back 
| to July.   Since then Mark has stood down, and Gershom has taken 
| over (thanks Gershom).  So I have a number of questions
| ?	Does the plan (attached) remain the same?
| ?	What development work (if any) , in HP or Cabal or 
|     stack, is needed to achieve that?  Is it done, or in 
|     progress, or not started?
| ?	GHC has for some time had the hooks to install multiple
|     instances of the same library without conflict, but Cabal 
|     does not (or did not).  I know Duncan was planning to do 
|     this.   Will the Cabal that comes with HP 8.0 have this ability?
|
| I ask because there is lots of traffic about getting GHC 8.0 
| ready for release, but I haven?t seen any about HP or Cabal.  
| Maybe I?m just not on the right mailing lists.
|
| Regardless, would it be worth some announcements so that the 
| Haskell community knows the plan?   If I don?t know, probably 
| many others do not.

I enclose three replies to that message, but the discussion 
never converged to a conclusion.

Since then Gershom did send an update about the HP, also attached,
but that didn't cover Cabal.

Much of this this pre-dates when you became chair, so you won't 
have seen it before, but you will be very familiar with the issues.
I'd love to know in more detail what you plan for Cabal and cabal-install,
esp concerning choices (1) and (2) outlined in Edward Yang's message attached.

thanks again

Simon

Subject: Cabal/cabal-install 1.24 release status
Message-ID: <CA+tcxkAorWy64vxyoNGZVaa9Xbgt=-v-0sauL+d4GSyhLBkbgQ@mail.gmail.com>

Hi *,

As some of you know, I've recently been elected as Cabal "chair"/release
coordinator. GHC 8/Cabal 1.24 release date is fast approaching, so I'll try to
summarise my current plans regarding the next release.


Release schedule:

* I'll create the 1.24 branch in about two weeks' time (Dec. 30 let's say).

* GHC 8 RC1 will be using Cabal HEAD/1.23.

* If there will be a GHC 8 RC2 (Herbert tells me it's very likely), it'll use
  the Cabal 1.24 pre-release (1.24 branch).

* Cabal 1.24 final will be released simultaneously with GHC 8 (maybe a bit
  earlier).

* cabal-install 1.24 will be released either simultaneously with Cabal 1.24, or
  soon after. I don't want to delay it by much.


Cabal patches I'd like to see in 1.24:

* Library support for Duncan's nix-local-build branch. This has just went
  in (#2948).

* Kristen's improved 'Setup configure' (#2925). Needs a review.

* Edsko's foreign library patches (#2540). Mostly ready to go in, but needs
  rebasing and some additional review.

* **/* globbing (#2522). I want to rework it a bit.

* (Possibly) #2829 - Thomas's reconfigure work, though he seems to have
  abandoned it.


cabal-install patches I'd like to see in 1.24:

* hackage-security. Duncan tells me that Edsko is working on it right at
  the moment, and some preliminary patches have already been merged. We may
  delay cabal-install's release a bit to get this in.

* Duncan's nix-local-build work in some form. This release will probably be a
  "technical preview".

* Andres's solver patches (#2731). Needs tests.

* Kristen's solver improvements (#2917, #2916, #2914). Would be nice if Andres
  could do a review.

* 'gen-bounds' (#2774).

* 'user-config init' (either #2640 or #2604).


Comments welcome!


Some other TODO items on my list:

* Gershom/Haskell.org are willing to allocate some build bot time to us for
  producing cabal-install binaries (Windows/OS X/Linux) and possibly
  nightlies. This will need a patch to ghc-builder [2], but should in principle
  be not that hard to set up. GitHub Releases can be used for hosting downloads.

* Revamp the web site [3]. I'd like to set up a news feed/blog and start posting
  monthly news updates akin to what haskell-mode devs have been doing [4].

* Reorganise the user guide. We need to put more focus on the 'cabal' tool and
  less on the 'Setup.hs' interface.


If someone is willing to help me with these three last ones, it'd be
appreciated!

I've just posted a status update to the cabal-dev mailing list:

http://article.gmane.org/gmane.comp.lang.haskell.cabal.devel/10456

Cabal/cabal-install 1.24 will include Duncan's no-reinstall work in
some form (likely a "technical preview"). The Cabal library parts have
just been merged. Gershom's minimal HP patch is already in Cabal
master.

It's possible that cabal-install 1.24 will not be released
simultaneously with Cabal 1.24, so the HP 8 release may also be
delayed a little bit.

Thanks Mikhail

When you make the release, do advertise to us non-Cabal-experts about the new no-reinstall ability and how to use it.  It's a game-changer.

Edward's blog post describes the issue
http://blog.ezyang.com/2015/09/is-no-reinstall-cabal-coming-to-ghc-8/
Having another blog post describing the solution would be excellent; with pointers from the Cabal home page.

Simon

Cabal 1.22.6.0 and cabal-install 1.22.7.0 (with Cabal 1.22.6.0) have both
been released and are available on hackage.

I am still pushing the changes to the Cabal downloads page, this should be
