patch applied (cabal): Add a unuque identifier for installed packages (part 1 of 9)
by Duncan Coutts 22 Aug '09

Thu Aug 6 06:19:28 PDT 2009 Simon Marlow <marlowsd(a)gmail.com> * Add a unuque identifier for installed packages (part 1 of 9) Ignore-this: b774e5719e666baee504e1f52381cc8b NOTE: the patch has been split into 9 pieces for easy reviewing, the individual pieces won't build on their own. Part 1 does the following: Distribution.Package: - define the InstalledPackageId type as a newtype of String Distribution.InstalledPackageInfo: - add an installedPackageId field to InstalledPackageInfo - change the type of the depends field from [PackageIdentifier] to [InstalledPackageId] The idea behind this change is to add a way to uniquely identify installed packages, letting us decouple the identity of an installed package instance from its package name and version. The benefits of this are - We get to detect when a package is broken because its dependencies have been recompiled, or because it is being used with a different package than it was compiled against. - We have the possibility of having multiple instances of a given <package>-<version> installed at the same time. In the future this might be used for "ways". It might also be useful during the process of upgrading/recompiling packages.

[Hackage] #575: Cabal configure leaves behind temporary files on Windows

#575: Cabal configure leaves behind temporary files on Windows ----------------------------------+----------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.2 Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.10.1 Platform: Windows | ----------------------------------+----------------------------------------- Every time 'configure' is run on Windows, a single .exe is left behind in the user's %TEMP% directory and is never removed. The problem is in checkForeignDeps in Distribution.Simple.Configure, specifically when GCC is run in builds. A temporary filename is created to hold the output, but it has no extension. When GCC is given this filename for output it appends .exe extension automatically. Since this is a different filename it never gets removed. Fix is to specify an extension for the output, like ".tmp", so GCC will actually put it there. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/575> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Changelogs and "available since"
by Laszlo Nagy 18 Aug '09

Hi All, I was volunteer to solve this problem: <http://hackage.haskell.org/trac/summer-of-code/ticket/1565> In a conversation on the libraries(a)haskell.org I was suggested to scratch my idea here. I would use hoogle for this. Currently it stores the package name and the symbols of the modules about a package. I would extend it to store the version of the package as well. Extend the query methods to use all the available package description at search. And make a VersionRange from the matched Versions. In a second turn I have to solve the problem, how a user can get all the hoogle files about every version of the used packages. (Applied version policy can help to have less files.) #1 Using a central repository, (like hackage) where upload require hoogle input file as well. #2 Implement a tool, top of (or inside) cabal-install, which generates all the needed files. Finally Haddock has to be taught to query hoogle to get availability description for each symbol. Please feel free to suggest other ideas or tell your opinion about mine. Regards, Laszlo

darcs patch: Add --html for haddock command.

Sun Aug 16 02:40:17 BST 2009 Thomas Schilling <nominolo(a)googlemail.com> * Add --html for haddock command. This makes it easier to build both html documentation and a hoogle database: ./setup haddock [--html] # build only HTML docs (default) ./setup haddock --hoogle # build only Hoogle DB ./setup haddock --hoogle --html # build both

[Hackage] #467: Add support for HPC profiling.

#467: Add support for HPC profiling. ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: normal | Ghcversion: Platform: | ----------------------------+----------------------------------------------- Similar to how we support ghc's "normal" profiling way, we should enable support to build packages with hpc turned on. This would also eliminate the need for people to add support on a per- package basis, see eg #430. See also #200. We should consider how to support these various flavours of profiling in a more extensible way. Different compilers have different ways, for example nhc has several (especially when used with hat). -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/467> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

patch applied (cabal): Use a simpler method for the check on the base-upper-bound
by Duncan Coutts 12 Aug '09

Wed Aug 12 06:33:13 PDT 2009 Duncan Coutts <duncan(a)haskell.org> * Use a simpler method for the check on the base-upper-bound Ignore-this: 9234cc76670a135906c8b7d2e19e6199 The key point is that we do not complain for packages that do not depend on base at all (like ghc-prim).

Duncan asked me to split up the patch to make it easier to digest. So here it is, in 10 pieces (one of which is just a refactoring).
