Cabal and simultaneous installations of the same package
by Simon Peyton Jones 29 Aug '15

29 Aug '15

Dear Cabal developers You'll probably have seen the thread about the Haskell Platform. Among other things, this point arose: | Another thing we should fix is the (now false) impression that HP gets in | the way of installing other packages and versions due to cabal hell. People mean different things by "cabal hell", but the inability to simultaneously install multiple versions of the same package, compiled against different dependencies is certainly one of them, and I think it is the one that Yitzchak is referring to here. But some time now GHC has allowed multiple versions of the same package (compiled against different dependencies) to be installed simultaneously. So all we need to do is to fix Cabal to allow it too, and thereby kill of a huge class of cabal-hell problems at one blow. But time has passed and it hasn't happened. Is this because I'm misunderstanding? Or because it is harder than I think? Or because there are much bigger problems? Or because there is insufficient effort available? Or what? Unless I'm way off beam, this "multiple installations of the same package" thing has been a huge pain forever, and the solution is within our grasp. What's stopping us grasping it? Simon

ANN: Cabal and cabal-install 1.22.3.0 released
by Ryan Thomas 06 May '15

06 May '15

A minor release of Cabal and cabal-install has been completed. This is available for download on haskell.org as well as hackage. The main reason for this release was a fix for the ghcjs-pkg version number handling. The changelog entries for both are below. Cabal: 1.22.3.0 Ryan Thomas <ryan(a)ryant.org> April 2015 * Fix for the ghcjs-pkg version number handling (Luite Stegeman) * filterConfigureFlags: filter more flags (Mikhail Glushenkov) * Cabal check will fail on -fprof-auto passed as a ghc-option - Fixes #2479 (John Chee) cabal-install: 1.22.3.0 Ryan Thomas <ryan(a)ryant.org> April 2015 * Fix bash completion for sandbox subcommands - Fixes #2513 (Mikhail Glushenkov) * filterConfigureFlags: filter more flags (Mikhail Glushenkov) Miëtek, Mikhail: If you would be willing to build the additional binaries as was done with 1.22.2.0 I will update the downloads page with them too. Cheers, Ryan

Cabal and cabal-install minor release (1.22.2.0)
by Ryan Thomas 06 May '15

06 May '15

I have released both Cabal and cabal-install 1.22.2.0 today, cabal-install has just gone out now. These have been published to Hackage and are available on the download page of haskell.org. As a part of this process I have also updated the release documentation (https://github.com/haskell/cabal/wiki/Making-a-release) to support the new sftp-only push to haskell.org. There are a couple of outstanding items to tie off with this release: - The {Cabal|cabal-install}-latest symlinks on haskell.org still need to be updated - The Windows/OSX/Linux specific binaries need to be built and updated on the download page; Johan I will probably need some guidance on the process for this. Once I get these items tied off, my main focus will be the automation of this release process. Cheers, ryan

Is there an open ticket for the issues you experienced? The only remaining problem that I know of is that the script sometimes picks dependency versions poorly; that's something we're set up to solve now. You can read about the tools in development here: https://github.com/fpco/stackage-server/issues/95 > But for Haskell to be a robust multi-platform portable language > we need to keep it simple.

Cabal has already become > far too complex to be in such a critical role for bootstrapping. The solution you propose adds to that complexity. Under your proposal, to bootstrap cabal-install, a user needs to: 1. Download cabal-bootstrap. 2. Install curl or equivalent, if it's not part of their usual platform (Windows). 3. Download and install a large number of dependencies, and finally cabal-install. Why is there an extra step at the beginning? Why does the user need to install curl only to immediately replace it? In contrast, under the Gershom's proposal, which I am endorsing, the user only needs to: 1. Install curl or equivalent, if it's not part of their usual platform (Windows). 2. Download and install a smaller number of dependencies, and finally cabal-install. That's a much simpler process. Having a separate bootstrap system is just adding a step: once curl or an equivalent is available on the user's system, there is no reason not to keep using it! I don't see any reason to believe any library will do a better job. Cabal is already very good at detecting available command-line utilities and managing alternatives. Regards, Tom

Making cabal-install SSL capable
by Gershom B 30 Apr '15

30 Apr '15

So there are many discussions over various hackage security schemes, and there are a variety of takes on the different elements of how we could make package distribution more secure. However, everyone seems to agree that it would be unambiguously better if the cabal install executable were able to communicate over ssl. I looked at the previous discussion on this topic [1], and it seems that HsOpenSSL and tls were both considered. I don’t have any experience with how cross-platform compatible HsOpenSSL is (i.e. if it is sufficiently easy to use for both Windows and OS X that we can just encourage people to “cabal install cabal-install” and things will just work). I don’t know if anyone else can speak to this? Furthermore, of course, redistributing cabal-install binaries could potentially be more of a pain with links to external c libraries. I’m not quite sure how much an issue this would be. Meanwhile, tls is certainly cross-platform, but there is the question about how trustworthy it is, as it is not nearly as widely used and vetted as openssl. Also, we have the option of simply shelling out to curl, wget, or the appropriate powershell command (on windows 7 or above you get those by default). So rather than rely on either HsOpenSSL or tls, we could also teach cabal to probe for one of the appropriate executables on first run, save that configuration, and warn if no such executable is available (allowing the user to fall back to http with warnings indefinitely). I would like to pursue getting SSL into cabal by any of these three avenues. What do people feel about the relative tradeoffs of these options? Honestly, I lean towards simply using the tls package, because https is ultimately only going to be a complimentary aspect of our security architecture plans and not central to it. And a pure-haskell dependency is the most logical approach. If people find too much fault with that approach, I would be inclined to shell out as the next option, with HsOpenSSL as the last option only because I worry about too many “unknown unknowns” of the sort I listed above. But if others have more experience with these approaches, proposals are welcome! —Gershom

How to compile git-annex?
by Peng Yu 26 Apr '15

26 Apr '15

Hi, I got too many error messages when I try to install git-annex. Is there a good way to fix them? Why cabal install print so many irrelevant messages?
