[Hackage] #380: Ability to blacklist packages that are on hackage

#380: Ability to blacklist packages that are on hackage ---------------------------------+------------------------------------------ Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: wishlist blacklist Difficulty: normal | Ghcversion: 6.8.3 Platform: | ---------------------------------+------------------------------------------ Sometimes there are packages on hackage that I don't want to install, perhaps ever. Maybe there is a buggy release I'm trying to avoid, or something of that nature. So, my proposal is a user defined blacklist. I think the version specification could work just like that of a .cabal file. I also think cabal should tell you when it skips a dependency due to blacklisting. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/380> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Instead, 'cabal install' without a package name argument should inspect whether the package is already configured and use whatever options have been set. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/309> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#294: Setup build should call Setup configure, if necessary ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: Severity: minor | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- If you change the Cabal description file of your project, you need to reconfigure it by calling ''Setup.lhs config'' (assuming that your Setup program is called ''Setup.lhs''). Since most editors don't know anything about Cabal, that requires you to have a shell open and type the command in question manually, which can get quite annoying, if you reconfigure often. ''Setup.lhs build'' recognizes the case, when the configuration has changed and dies with an error. It would be very useful, if it would call the ''configure'' command automatically instead, for example with the last used flags, or with a default set of flags configured in the description file. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/294> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Three (all from different authors, and only looking at those with "string" as a substring of the name!) include stringtable-atom, bytestring-csv and packedstring.

#371: cabal-install can break installed packages by rebuilding dependents ---------------------------------+------------------------------------------ Reporter: duncan | 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: | ---------------------------------+------------------------------------------ Install plans sometime involve rebuilding a package. This is not a safe operation however. Rebuilding a package can and does change its ABI. The ideal solution is to use a persistent package store like nix. That would mean we do not replace any installed package, just add new instances. In the mean time however one solution would be to extend an install plan the re-installs a package such that it rebuilds all reverse dependencies too. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/371> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

This means, for instance, that one can't view it in the offline documentation distributed with GHC. It's also not directly linked from http://www.haskell.org/cabal/, making it altogether a bit better hidden than it should be. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/386> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #303: cabal clean: Error while removing dist/: dist/setup: removeDirectory: unsatisified constraints (Directory not empty)

#303: cabal clean: Error while removing dist/: dist/setup: removeDirectory: unsatisified constraints (Directory not empty) ----------------------------+----------------------------------------------- Reporter: simonmar | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.4.0.1 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ----------------------------+----------------------------------------------- cabal clean has a problem on Windows and Unix with NFS that causes it to fail when using a custom `Setup.hs`. The problem is that we compile `Setup.hs` to `dist/setup/setup`, and then invoke `dist/setup/setup clean` which is supposed to remove the whole of the `dist` tree, including the running binary. This causes problems on Windows where running binaries can't be deleted, and also on NFS where deleting the running binary leaves a `.nfs` file behind, preventing the parent directory from being deleted. {{{ > cabal clean -v Creating dist/setup (and its parents) dist/setup/setup clean --verbose=2 --distpref=dist cleaning...
