Note that we still cannot avoid using the global package db, that is it'll fail if we use `--package-db=clear --package-db=foo` because ghc always looks at the global package db anyway.

[Hackage] #731: Custom Build-type with --package-db and --global encounters runtime error

#731: Custom Build-type with --package-db and --global encounters runtime error ---------------------------------+------------------------------------------ Reporter: cygnus | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.8.0.4 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: 6.12.2 Platform: Linux | ---------------------------------+------------------------------------------ To reproduce: * Run `cabal init`, change `Build-type` to `Custom` (`Setup.hs` already provided by `cabal init`) * Run `ghc-pkg init db` * Run `cabal configure --package-db=./db --global` * Output: {{{ Resolving dependencies... cabal: internal error: unexpected package db stack }}} In `cabal-install-0.8.2`, this appears to be caused by the code on lines 112-114 of `Distribution.Client.Configure`: {{{ usePackageDB = if UserPackageDB `elem` packageDBs then packageDBs else packageDBs ++ [UserPackageDB] }}} in combination with the code on lines 297-306 of `Distribution.Client.SetupWrapper`: {{{ ghcPackageDbOptions :: PackageDBStack -> [String] ghcPackageDbOptions dbstack = case dbstack of (GlobalPackageDB:UserPackageDB:dbs) -> concatMap specific dbs (GlobalPackageDB:dbs) -> "-no-user-package-conf" : concatMap specific dbs _ -> ierror where specific (SpecificPackageDB db) = [ "-package-conf", db ] specific _ = ierror ierror = error "internal error: unexpected package db stack" }}} Essentially, the order of the package databases in the stack is not as expected since the list already contains a `SpecificPackageDB` when the `UserPackageDB` is appended. (Note: this applies to GHC 6.12.3 and Cabal 1.8.0.6 on my system, but I could not select those versions in the ticket properties.) -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/731> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Test and benchmark dependencies could only be installed for source packages because no package description is available for named packages before dependency resolution. Now, test and benchmark stanzas are enabled or disabled through constraints passed to the dependency resolver. This way, we can install dependencies for the test suites of target packages without propagating '--enable-tests' through the entire dependency tree; i.e., tests and benchmarks, when enabled, are built only for target packages. Later, this will allow us to automatically run test suites and, e.g., install only upon their success.

[Hackage] #931: Support building source trees with many packages

#931: Support building source trees with many packages ---------------------------------+------------------------------------------ Reporter: tibbe | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.10.2.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ A not uncommon use case is building a package against a set of dependencies that exist in (unreleased) source form. For example, given two packages: {{{ $ ls hashable unordered-containers }}} I'd like to be able to {{{ $ cd unordered-containers cabal build --root=.. }}} Cabal should then recursively traverse directories from `--root`, looking for .cabal files to use when fulfilling dependencies (i.e. in this case it'd find `hashable`.) Those dependencies should also be marked as preferred to any Hackage versions of the package with the same version number. It'd also be convenient to add several `--root` flags, so one can specify specific packages to use in source form (without using e.g. the user's complete `~/src` directory.) {{{ $ cd unordered-containers cabal build --root=../hashable --root=../text }}} -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/931> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
