I haven’t looked at the code, but I assume it’s a simple mistake. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/372> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#299: Add changelog feature to hackagedb --------------------------------+------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: hackageDB website | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | --------------------------------+------------------------------------------- It would be great if releases on hackagedb were required (or even permitted) to include short descriptions of the changes made since the last release. Currently there is no easy way to get this information for most packages, since many packages have no home page other than their hackagedb page. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/299> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#171: Add command to automagically create an initial cabal package --------------------------+------------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.6 Platform: Linux | --------------------------+------------------------------------------------- Don Stewart has a nice tool called mkcabal (http://www.cse.unsw.edu.au/~dons/code/mkcabal/) which creates an initial cabal package. It would be nice to have this built into the 'cabal' program itself so that "cabal create" or "cabal init" or similar would interactively create a cabal package. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/171> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

In the HackageDB package overview, it is shown whether packages contain libraries and/or programs, but this does not seem to work correctly in all cases, as emgm demonstrates. kosmikus -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/385> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #423: add option to fetch a single package without dependencies

#423: add option to fetch a single package without dependencies ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ----------------------------+----------------------------------------------- Right now, {{{cabal fetch}}} fetches all missing dependencies of a package along with its source. In some cases, in particular when studying code, those dependencies are not useful. It would be nice to have an option, say {{{--no-deps}}} to fetch just the specified packages. (This is related to {{{cabal unpack}}} -- see #390.) -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/423> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #403: Bad error message when running ./configure fails to find sh

#403: Bad error message when running ./configure fails to find sh ----------------------------------+----------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: HEAD Severity: minor | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.10.1 Platform: Windows | ----------------------------------+----------------------------------------- For `build-type: Configure` we have to run `./configure`. On windows this will very often fail of course because they usually lack the `sh` program. Currently the error message users get is not great: {{{ sh: runGenProcess: does not exist (No such file or directory) }}} It would be nicer if they got a better message. Perhaps the way to do that is to catch the `DoesNotExist IOException` and re-throw a better message. Alternatively we could explicitly check for `sh` before invoking it. If it's not found on Windows then we could report that the package needs a unix-style command shell program eg from `mingw` to build. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/403> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #261: Marking packages deprecated

#261: Marking packages deprecated ----------------------------+----------------------------------------------- Reporter: nibro | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- There should be a way to mark a package as '''deprecated''' so it doesn't show up on the main Hackage listing. If a newer package, with the same name, is uploaded then the older packages will in effect be defunct. But if you don't have a newer package with the same name, there is currently no way to "get rid of" packages that are no longer valid. There may be several reasons for why you would want to do this, likely most often because the contents of the package are superceded by functionality in some other package, with a different name. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/261> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #282: profiling versions of libraries not managed well

#282: profiling versions of libraries not managed well ---------------------------------+------------------------------------------ Reporter: SamB | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: profiling Difficulty: normal | Ghcversion: 6.8.2 Platform: | ---------------------------------+------------------------------------------ At the moment, if you want profiling builds of libraries which you have already installed, the only way to get them is to unregister and rebuild with profiling turned on. This is especially inconvenient when you have a program that depends on many different libraries... Ideally, I could just add a flag to rebuild a program with profiling, regardless of whether I'd installed profiling versions or not... Any ideas on how this should be managed? What configurations should be allowed? How do we make sure the same library version is used for the profiling build as was used for the normal build? When do we just give up and make the user figure it out? -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/282> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #320: cooperation with Windows Vista's User Access Control

#320: cooperation with Windows Vista's User Access Control ----------------------------+----------------------------------------------- Reporter: Toxaris | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.4.0.1 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: Windows | ----------------------------+----------------------------------------------- Installation of a cabal package under Windows Vista with UAC activated may fail even when working as administrator, because cabal doesn't request the necessary rights to write to, e.g., "c:\Program Files\Haskell\<whatever>". A workaround is to start an "Administrator console" to start Cabal from a process which already acquired admin privileges. Cabal should request the necessary rights instead of failing. cabal-install should check in advance whether the target destination is writeable and fail early or request the necessary rights. (currently, cabal-install fails after compiling all dependencies. After starting cabal-install again from an Administrator console, everything has to be build again). {{{ C:\Downloads\Haskell\typeof-0.1.1>runhaskell Setup install Setup: C:\Program Files\Haskell\doc\typeof-0.1.1: copyFile: permission denied (P ermission denied) }}} -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/320> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
