Heads up - moving the bug tracker to github
by Bryan O'Sullivan 11 May '12

11 May '12

Hi folks - Some time next week, I am planning to import all open Cabal bugs into the github issue tracker. At that point, we should put the Trac issue tracker into read-only mode. Here's a preview of what the imported issues will look like: https://github.com/bos/test1/issues Most issue metadata is preserved, except for being able to attribute issues and their comments directly to users (github's API doesn't allow this).

[Hackage] #949: cabal should fail if compilation depends on a file not existing in the cabal file

#949: cabal should fail if compilation depends on a file not existing in the cabal file ---------------------------------+------------------------------------------ Reporter: LeventErkok | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.10.2.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ Cabal doesn't complain if the build depends on a Haskell module that exists in the filesystem properly, but is not mentioned in the cabal file itself as part of "exposed-modules" or "other-modules". The build succeeds because ghc can find the relevant file just fine. I've got bitten by this several times, especially after pushing a package to hackage, only to get it fail to build on the server because I've failed to put the name of a file in the appropriate section of the cabal file, thus it didn't make it to the .tar.gz bundle that got uploaded to the server. I realize this might be hard to ensure, as it would require a deeper look into the dependencies between modules, but I trust the GHC API should have all the information necessary for cabal to complain appropriately. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/949> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Andres and I discussed this the other day. I think our consensus was to use 'get' and to have that also work for tarballs (like the current 'unpack'). We didn't discuss in detail what a 'get' command would look like, e.g. how to say you want to get the scm version rather than the tarball version. Duncan

Darcs home page updated
by Simon Michael 30 Apr '12

30 Apr '12

With 2.8 released, I felt Darcs deserves better presentation. After surveying other VCS sites I worked on an update to our home page layout and content over the last few days, with review and input from #darcs, and it went live last night. It's far from perfect but I hope it's a good step forward. Thanks for the input, and have at it: http://darcs.net -Simon

[Hackage] #947: let "cabal -fSomeFlag" produce error for undeclared flags

[Hackage] #948: some way to specify common build-depends for library, executables and test-suites

#948: some way to specify common build-depends for library, executables and test- suites ---------------------------------+------------------------------------------ Reporter: Oblosys | Owner: Type: enhancement | Status: new Priority: low | Milestone: Component: cabal-install tool | Version: 1.10.2.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ Not sure whether this is a feature request or a bug report. I sometimes have a number of dependencies that are the same for library, executable, and test-suite. The global property 'build-depends' looks like an ideal place to put these, but any dependencies I list there seem to be ignored by cabal. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/948> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #946: Packages are downloaded insecurely

#946: Packages are downloaded insecurely ----------------------------+----------------------------------------------- Reporter: cooldude | Owner: Type: defect | Status: new Priority: high | Milestone: Component: Cabal library | Version: 1.10.2.0 Severity: major | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- It appears that when running cabal install package, the package is downloaded without any transport security. Anyone who can perform a man in the middle attack could tamper with the package that is being downloaded, resulting in a complete compromise of the cabal user. This makes it impossible to use cabal. The servers should utilize TLS, it is possible to get a free certificate from startcom if price is a concern. Additionally when packages are verified as non-malicious, they should be signed with a "cabal" signing key, and then the package signatures should be verified by cabal. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/946> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #780: Simpler support for isolated/sandboxed builds

#780: Simpler support for isolated/sandboxed builds ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ Cabal/cabal-install allows setting the install prefix and the package database. Together these allow creating isolated builds. This is clearly not sufficiently easy to use as there are now two projects that provide wrappers over cabal-install to provide more direct support for this use case: * http://github.com/creswick/cabal-dev/blob/master/README.md * http://www.haskell.org/haskellwiki/Capri The task is to investigate what user behaviour is desired and to integrate this in the best way with Cabal/cabal-install. This is probably related to: * ticket #556 about local config files (e.g. persistently setting some sandbox flag) * ticket #734 about supporting multiple local .cabal files * ticket #524 about supporting file, directory and url targets for packages and .cabal files -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/780> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
