Hi all, I've should have CCed cabal-devel on this discussion from the start. My apologies. I will try to remember to have all these discussion in the open in the future. We're discussing how the sandbox mechanism that cabal got during this year's GSoC should be exposed to users. I've included the discussion so far below: --8<----------------------- Date: Fri, 24 Aug 2012 15:40:14 -0700 Subject: Agreeing on a UI for sandboxes From: Johan Tibell <johan.tibell(a)gmail.com> To: Duncan Coutts <duncan.coutts(a)googlemail.com>, =?ISO-8859-1?Q?Andres_L=F6h?= <andres.loeh(a)googlemail.com>, Mikhail Glushenkov <the.dead.shall.rise(a)gmail.com> Hi all, I've now merged Mikhail's last patches and the remaining work is to figure out how to expose the sandbox mechanism to users in a way that easy to understand and convenient to use. Mikhail has added some hidden commands that you can use to today to work within the sandbox. The goal is to remove these commands in favor of modifying the behavior of the current command set. If we could bring out the different possible designs and issues before ICFP, perhaps we can solve any remaining issues in person there. Mikhail, as a starting point, could you please explain how you'd use these hidden commands (you can probably reuse your description from the pull request). -- Johan --8<----------------------- Date: Sat, 25 Aug 2012 01:01:04 +0200 Subject: Re: Agreeing on a UI for sandboxes From: Mikhail Glushenkov <the.dead.shall.rise(a)gmail.com> To: Johan Tibell <johan.tibell(a)gmail.com> Cc: Duncan Coutts <duncan.coutts(a)googlemail.com>, =?ISO-8859-1?Q?Andres_L=F6h?= <andres.loeh(a)googlemail.com> Hi all, On Sat, Aug 25, 2012 at 12:40 AM, Johan Tibell <johan.tibell(a)gmail.com> wrote: > Mikhail, as a starting point, could you please explain how you'd use > these hidden commands (you can probably reuse your description from > the pull request). There are four new hidden commands: * cabal sandbox-configure Same as 'cabal configure', but also initialises a new sandbox to be used for building. * cabal sandbox-add-source Makes a source package available for installation inside the sandbox. * cabal sandbox-build Builds a package inside the sandbox. * cabal sandbox-install Installs a package into the sandbox. I tried to keep the UI close to the current one, so dependency installation & configuration is still done manually. If a dependency added with sandbox-add-source is updated, it must be manually reinstalled with cabal sandbox-install LibName.

Not if the same version is already installed. We can change it so all dependencies added with add-source are always reinstalled when you run sandbox-install. I'm not quite satisfied with both the current and the proposed solution, ideally it'd possible to detect when some .hs files have changed and the package needs to be reinstalled. >> Here's an example session: >> >> $ git clone git://github.com/haskell/cabal.git >> $ cd cabal/cabal-install >> $ cabal sandbox-configure -w /path/to/ghc-7.4.1 > > So I can only create a sandbox in a Cabal package directory?

Good point, I'm also a bit uneasy about this. On the other hand, running 'sandbox-install --only-dependencies' directly after creating a sandbox is a common use case. I also don't like requiring the user to run 'sandbox-configure' twice.

We discussed this - the initial idea was to have a separate link-source command. Johan thinks that it is redundant and it would be best to avoid adding it. One idea is to make 'install' run 'cabal build' on packages added with add-source (those that we depend on) and then only install those files that have actually changed (so that re-linking is avoided). > And I guess you can > add-source not only local packages, right? The plan is to allow linking to remote repositories. This is not yet implemented. >>> I'm not particularly fond of having non-install commands download >>> stuff from the internet. >> >> Good point, I'm also a bit uneasy about this.

I think that I'll make sandbox-install initialise a sandbox by default because of this use case: $ mkdir darcs && cd darcs $ cabal sandbox-install darcs But using 'install' for building feels inconsistent. For the normal build you are using 'cabal configure && cabal install --only-dependencies && cabal build'. For the sandboxed build you would be using 'cabal install --sandbox'. Ideally, I'd like the differences between workflows to be minimal. Assuming that the standard commands were made sandbox-aware: $ cabal configure --sandbox $ cabal install --only-dependencies $ cabal build But configure fails when the sandbox is empty, so one has to run it twice. --8<----------------------- Date: Tue, 28 Aug 2012 16:45:55 -0700 Subject: Re: Agreeing on a UI for sandboxes From: Johan Tibell <johan.tibell(a)gmail.com> To: Mikhail Glushenkov <the.dead.shall.rise(a)gmail.com> Cc: =?ISO-8859-1?Q?Andres_L=F6h?= <andres.loeh(a)googlemail.com>, Duncan Coutts <duncan.coutts(a)googlemail.com> Hi, I haven't had time to collect my thoughts fully yet, so here are some initial thoughts: It's important that users don't use a mix of sandbox and non-sandbox commands by misstake. That would lead to confusing build errors. Ideally the users should request that work is to be done in a sandbox once and then all commands should use the sandbox. This means that there should be no e.g. cabal build/test/bench --sandbox flags. Perhaps a separate command, cabal init-sandbox, would be the best approach. Running that command would create the right package environment for running in a sandbox and the remaining commands would then use that sandbox. Separating init-sandbox from configure prevents the user from removing the sandbox preference when reconfiguring for some other reason (e.g. to add --enable-tests). To get out of the sandbox the user would edit the package environment file. Alternatively we could have a sandbox command that lets you both add and remove sandboxes. cabal sandbox --init cabal sandbox --delete cabal sandbox --init --path=/path/to/sandbox -- Johan --8<----------------------- Date: Tue, 28 Aug 2012 16:56:20 -0700 Subject: Re: Agreeing on a UI for sandboxes From: Johan Tibell <johan.tibell(a)gmail.com> To: =?ISO-8859-1?Q?Andres_L=F6h?= <andres.loeh(a)googlemail.com> Cc: Mikhail Glushenkov <the.dead.shall.rise(a)gmail.com>, Duncan Coutts <duncan.coutts(a)googlemail.com> On Mon, Aug 27, 2012 at 11:28 PM, Andres L=F6h <andres.loeh(a)googlemail.com>= wrote: >> We can change it so all >> dependencies added with add-source are always reinstalled when you run >> sandbox-install. > > I wouldn't change it yet.

And I guess you can > add-source not only local packages, right? I'm worried about making cabal even more cumbersome to use. Today you need to do the following to work on several repos at once: for every dependency: cd $dir cabal configure cabal build cd $main-dir cabal configure --package-db=3D$dir1/dist/package.conf.inplace --package-db=3D$dir1/dist/package.conf.inplace ... If the use manually has to rebuild dependencies every time the change even when using a sandbox we have essentially no improvement over status quo and or cabal-dev. Cabal today is too much about mechanism and not enough about user intentions. Lets try to move it towards the latter, not away from it. Here's my claim, if rebuilding my project requires something more than "cabal build", we did something wrong in designing the user interface. -- Johan

New cabal-install release (and schedule) needed
by Bryan O'Sullivan 27 Aug '12

27 Aug '12

We need to publish a new cabal-install 0.16 release shortly, ideally before GHC 7.6.1 and the next Haskell Platform come out. At the very least, there's a newish incompatibility between GHC 7.6 and cabal-install that causes all -Werror builds to fail because cabal-install uses a deprecated package flag. This was fixed back in May, but that needs to actually go out into the wild. Stepping back, I'd also like to suggest that we move to a quarterly release cycle on a simple, widely used model. A major goal here is to get code into people's hands on a predictable schedule. We maintain two branches, stable and master. Master freezes a month before a release, with only bugfixes and typo fixes going in. At release time, the stable branch opens (in case any emergency fixes are needed), and master opens up for normal development again. Johan and I are happy to do the work to manage these cycles. I suggest that we start the first cycle with a target release date of the end of September, then go four months to the next one (after all, it would be unrealistic to pretend that we might do a release at the end of December). Does this sound reasonable?

Some possible solutions for the dependency issues
by Chris Moline 25 Aug '12

25 Aug '12

Hi, so with all the furor over dependency hell I've been thinking about how to address the issue. I've come up with an approach that I'm willing to try to implement, if it's sensible. First is using explicitly versioned libraries and executables. For example, using 'alex-3.0.2' instead of just 'alex'. Next is implementing the suggestion for soft and hard upper bounds. Hard upper bounds would be denoted by a duplicated first character of the relevant operator, ie, <<, <<=, ===. Finally, if an install fails because of dependency versioning issues, automated support for fixing these issues would kick in, probably after prompting the user if they want to attempt it, or after issuing a command such as 'cabal repair'. There would be integration with bug reporting and bug report search so that if there are problems that are more than the user wants to deal with the bug report could be submitted easily. This functionality would be available with the command 'cabal submit-issue'. If the repair was successful patches would be submitted to the maintainer after checking that similar patches haven't been submitted already. Maybe it could be useful for cabal to provide convenient means of communicating with the package maintainer. For example, instead of having to subscribe to the mailing list for gtk 'cabal submit-issue' would present the results of search to see if the issue was already brought up. If the user doesn't think anything relevant came up they could then be presented with a form for filing a bug report. After that the user would be kept in the loop without having to subscribe to the mailing list. So does this sound like a useful solution?

Cabal install solver as a library
by Benjamin Edwards 20 Aug '12

20 Aug '12

Hi, Was looking at some slides from well typed ( http://www.haskell.org/wikiupload/b/b4/HIW2011-Talk-Loeh.pdf) which suggested that at some point cabal-install would be available as a lib. I am currently trying to get cabal to play nicely with meta-build systems and it would be great if I could dump install plans in json or similar. Is there anyone looking at this? Is it feasible? Would someone be available to mentor such a change if I volunteered some time? Ben
