#435: ban upwardly open version ranges in dependencies on base ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ----------------------------+----------------------------------------------- This is wrong! {{{ build-depends: base }}} This is still wrong! {{{ build-depends: base >= 3 }}} Each major release of the base package breaks most packages. Packages should specify an upper bound on the base version. Eg: {{{ build-depends: base >= 3 && < 4 }}} or equivalently: {{{ build-depends: base == 3.* }}} Cabal should check for this and suggest a sensible upper version on the base package, given that we know that base follows the package version policy. Note this is a special case for base but in general we should do this for all packages that opt-in to the versioning policy (see #343). Doing it for all such packages is a medium term goal. Doing it for base is quick and easy and has a lot of immediate benefits for the next release of base. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/435> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

I found this useful - see http://code.haskell.org/asn1/Setup.hs for an example. Dominic.

Thus in the package description at http://hackage.haskell.org/cgi-bin/hackage-scripts/package/cabal-install the word "Distribution" should be a link to http://hackage.haskell.org/packages/archive/pkg- list.html#cat:Distribution This way one can easily browse for other packages of the same category. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/417> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

It would be very useful if there was a stable URL where the documentation of the latest version of a package could be found. -- Neil Mitchell -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/273> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#488: Include links to GHC documentation in packages' haddock docs --------------------------------+------------------------------------------- Reporter: SamB | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: hackageDB website | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | --------------------------------+------------------------------------------- It would be really nice if packages' haddock documentation didn't have broken (well, missing) links whenever it refers to GHC core packages that aren't also on hackage. Even nicer would be if dependencies on GHC core packages also linked to their Haddock documentation. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/488> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #318: Library cannnot be used when registered in-place on OS X

#318: Library cannnot be used when registered in-place on OS X ---------------------------------+------------------------------------------ Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.4.0.1 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: Mac OS | ---------------------------------+------------------------------------------ I built and registered a library --inplace using cabal-install on Mac OS X 10.5.4 using cabal-install 0.5.1 and Cabal 1.4.0.1. I was unable to then use the package afterwards. It failed at link-time with: {{{ Linking Main ... ld: in /... blah .../lib/dist/build/lib-0.1.a, archive has no table of contents collect2: ld returned 1 exit status }}} After talking to Beelsebob and dcoutts on #haskell, I used '''ranlib''' on lib-0.1.a, and it worked. According to dcoutts: "it's because we run ranlib when we install it, but not when we first generate it." -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/318> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #549: The reason for an upload error is not reported

See also #338. Apparently this also affects download, not only upload. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/549> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#185: Temporary executables leave foo.exe.manifest files behind ----------------------+----------------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal | Version: HEAD Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.1 Platform: Windows | ----------------------+----------------------------------------------------- When Cabal creates and runs a temporary program, as it appears to do with hsc when running over the base libraries doing haddock, it leaves a manifest behind in dist. On Windows, ghc --make with 6.8.1 produces a foo.exe and a foo.exe.manifest. Cabal deletes the former, but not the latter. Very minor, but should be easy to fix too. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/185> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

that test hook
by Peter Gammie 02 Jun '09

02 Jun '09

Hello, I see from the archives that this hook is much unloved. How is one supposed to use it? The arguments to the function are underspecified. What is the Bool? I want access to the command-line flags, or at least verbosity settings. How do I do that? I envisage testing like so (approx): Setup test file Setup test dir Setup test --verbose Has anyone used it in anger? cheers peter
