#199: when installing a new version of GHC, there should be a way to upgrade my packages ---------------------------------+------------------------------------------ Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: Linux | ---------------------------------+------------------------------------------ If I have version 6.6 of GHC installed, with packages foo, bar, and bang, and I install ghc 6.8, I'd like a way to automatically install foo, bar, and bang. This could be part of GHC's installation script possibly, or maybe a feature of cabal install. cabal can check the installed packages for the previous version of GHC and "cabal install" them. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/199> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#330: Take non-haddock documentation in account ----------------------------+----------------------------------------------- Reporter: fons | 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: | ----------------------------+----------------------------------------------- The generation and installation of Non-Haddock documentation (README and INSTALL files, LaTeX and Docbook tutorials/guides, Haskell examples using the package in question) is not currently taken in account by Cabal. Making Cabal understand how to generate documentation for all those formats would probably be too ambitious, but it could be eased (e.g. letting the user provide Makefiles instead of creating custom hooks). More importantly, the installation of documentation would be much easier with a new package property such as "doc-files" ("data-files" nor "extra- source-files" are semantically suitable). -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/330> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

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

#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

#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

[Hackage] #231: "buildable: False" should fail the current configuration

#231: "buildable: False" should fail the current configuration ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- Currently resolving configurations does not take account of the `buildable` field. It should act rather like `build-depends: non- existant`, though with a different error message. If possible the error message should relate to the guard condition expression (the conjunction if there are several nested guards). At the moment it is not considered at all and we don't notice that the package cannot be built until the build step, rather than the configure step. One problem is that it's not clear if `buildable: False` is always fatal. People sometimes do that for test executables that are not supposed to be installed. So what should the behaviour be? The lib or only exe failing to configure must be an error. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/231> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#338: use of HTTP needs overhauling ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ---------------------------------+------------------------------------------ We're not using HTTP the protocol or HTTP the package effectively * As I understand it, the HTTP lib buffers the entire http download in memory rather than returning it lazily, so we cannot stream it to disk. It's also all done using `String`. * We do not check (and nor does the HTTP lib) for truncated downloads. That is where the `Content-Length` header differs from the actual length. * We do not cache the ETag so we cannot optimise the case of re- downloading an unchanged index. * We make a new tcp connection for each download, rather than doing all downloads within a single browse session. * We are not doing downloads concurrent with package builds. We should probably use a dedicated thread for downloads. It should serialise downloads and use a single browse session. Even without support for streaming the body directly we could at least write files atomically, checking length header. And also cache the ETag. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/338> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
