#766: hackage build logs gone missing? --------------------------------+------------------------------------------- Reporter: claus | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: hackageDB website | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | --------------------------------+------------------------------------------- It seems that build logs are no longer linked from package pages (used to be linked from the `built on` entries, iirc), such as: http://hackage.haskell.org/package/haddock Also, the `latest/` directory has `doc/`, but not `logs/`, while the archived versioned directory has both: http://hackage.haskell.org/packages/archive/haddock/latest/ http://hackage.haskell.org/packages/archive/haddock/2.8.1/ And, since I've more than once confused myself with that directory structure (`package` singular, but `packages/archive` plural? why the different prefix, where a version number postfix should be enough? why both `http://hackage.haskell.org/package/haddock-2.8.0` and `http://hackage.haskell.org/packages/archive/haddock/2.8.0/`?), could that be simplified (or, at least, a link be provided from the `package`-entry to the shadow-hierarchy `packages/archive`)? -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/766> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #895: Mis-parses curly braces in package description

#895: Mis-parses curly braces in package description ----------------------------+----------------------------------------------- Reporter: nomeata | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- Curly braces can be used to replace the layout rule in cabal file. This features seems to go wrong when curly braces are used in the description field, where they are also replaced by line breaks or something similar. This is inconvenient for those trying to give good documentation already in the description, e.g. http://hackage.haskell.org/package/BlogLiterately and http://hackage.haskell.org/package/hamlet Curly braces inside the description (or probably inside any field) should be left alone; or at least some escaping mechanisms needs to be provided. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/895> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #832: Cabal aggregates dependencies for executables

#832: Cabal aggregates dependencies for executables ----------------------------+----------------------------------------------- Reporter: juhp | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.10.1.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- I discovered over the weekend while trying to subpackage bluetile, that Cabal seems to aggregate dependencies of executables. For example http://hackage.haskell.org/packages/archive/bluetile/0.5.3/bluetile.cabal generates several executables. Some depend on gtk, others not, and yet Cabal passes "--package-id gtk-..." to "ghc --make" for all of them and as a result the bluetile program (which doesn't depend on gtk) gets linked against gtk (and glade), leading to executable/dependency bloat. Only the executables that are listed with explicit build-depends on gtk should be linked against the gtk package, etc. I will try to dig into the source later and maybe even cook up a patch if I can: a code pointer would be appreciated. I assume Cabal is currently just accumulating all the build-depends which is sub-optimal. (Arguably ghc shouldn't link unused libraries to executables either, though I think that is pretty standard compiler behaviour. But I can file a bug against ghc too if appropriate.) -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/832> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#830: Use wide Windows APIs in Cabal -----------------------------+---------------------------------------------- Reporter: batterseapower | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: HEAD Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | -----------------------------+---------------------------------------------- As part of my work on GHC's Unicode support (http://hackage.haskell.org/trac/ghc/wiki/Status/Encoding-Tickets) I identified some potential Unicode problems in Cabal install. The attached patch resolves them: 1. Use wide (UTF-16) APIs to retrieve file paths 2. Use withFilePath (from base) when marshalling a file path, as this will do the Right Thing when my changes are committed, though it is functionally equivalent to withCAString right now.

[Hackage] #802: copy command should not overwrite files

#802: copy command should not overwrite files ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- see http://hackage.haskell.org/trac/ghc/ticket/4955 Cabal can inadvertently get users into situations where they have registered packages that do not match their package registration information. Consider the package darcs and darcs-fastconvert which depends on the darcs library. If one installs darcs, then later in the darcs build tree do a `cabal copy` then it will overwrite the library .hi files but not update the library registration. This will mean that subsequent builds of darcs-fastconvert will fail with very confusing error messages (see the ghc ticket above). A similar thing could happen with inplace registrations. The suggestion to avoid this problem is for `cabal copy` to refuse to overwrite .hi files (executables are fine). This is also partly related to #645 because some people are using `cabal copy` to avoid having to use `cabal install` which spends too long reconfiguring and checking nothing needs building before actually installing. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/802> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
