      Change rep of module re-exports, and do resolution ourselves · a3d3273a
      Duncan Coutts authored
      The initial support for module re-exports relied on ghc-pkg to resolve
      user-specified re-exports to references to specific installed packages.
      This resolution is something that can fail so it's better for Cabal to
      do it during the package configure phase.
      In addition, it is inconvenient in ghc-pkg to be doing this resolution,
      and it just seems fishy as a design. Also, the same ModuleExport type
      was being used both for user-specified source re-exports and also for
      the specific re-exports in the package db.
      This patch splits the type into two: one for source level, and one for
      resolved ones for use in the package db. The configure phase resolves
      one to the other.
      One minor change: it is now possible to re-export a module defined in
      the same package that is not itself exported (ie it's in other-modules,
      rather than exposed-modules). Previously for modules definied in the
      same package they had to be themselves exported. Of course for
      re-exports from other packages they have to be exposed.

      Bump version. · 7a24dd6a

      So that the 'install_from_tarball' build bot step doesn't try to use the old
      1.21 snapshot that comes with GHC HEAD.

      Fix regression for V09 test library handling. · 2b50d0a7
      Edward Z. Yang authored
      detailed-1.0 test libraries allow users to define a test library as part
      of package, which has a different package ID than the original library.
      When I made the change to packageKey, I forgot to assign new package keys
      here; the result was that the test library was compiled with the same
      package key as the original.  The fix is a bit of a hack, since arguably
      this should have been done properly in the configure step!

      Implement package keys, distinguishing packages built with different deps/flags · 41610a0b
      Edward Z. Yang authored
      Previously, the GHC ecosystem assumed that for any package ID (foo-0.1), there
      would only be one instance of it in the installed packages database.  This
      posed problems for situations where you want a package compiled twice against
      different sets of dependencies: they could not both exist in the package
      Package keys are a hash of the package ID and package
      dependencies, which identify a package more uniquely than a package ID, but less
      uniquely than an installed package ID. Unlike installed package IDs, these can
      be computed immediately after dependency resolution, rather than after
      compilation.  Package keys require support from the compiler.  At the moment,
      only GHC 7.10 supports package keys (the reason is that old versions of GHC
      do a sannity check to see that the <pkg-name>-<pkg-version> stored in the
      package database matches with the -package-name embedded in an hi file; so
      the format is fixed.) We fallback to package keys == package IDs for old
      Note: the ./Setup configure fallback script does not try particularly hard to
      pick consistent sets of dependencies.  If your package database is too difficult
      for it to resolve, manually provide installed package IDs or use cabal-install's
      dependency solver.
      Note: This patch *suspends* the reinstall check unless it would result in
      a different package, so cabal-install will now happily reinstall foo-0.1
      compiled against bar-0.2 if foo-0.1 already exists.

      Weaken dependency on process. · ebd4d4b9
      Edward Z. Yang authored
      GHC 7.6 still distributes by default with an old version of process, which
      means that requiring the most recent version prevents GHC from properly
      bootstrapping out of the box.  In this patch, we relax the version requirement
      on process, disabling proper ctl-c handling when the version is not sufficiently
      Perhaps one problem with lowering the bound, is if someone attempts to install
      Cabal out of the box on GHC 7.6, the dependency solver will prefer the old
      installed version, so it is very easy to end up with a cabal-install which
      doesn't have working ctl-c.

      Implement "reexported-modules" field, towards fixing GHC bug #8407. · 62450f9a
      Edward Z. Yang authored
      Re-exported modules allow packages to reexport modules from their
      dependencies without having to create stub files.  Reexports of the same
      original module don't count as ambiguous imports when module finding
      occurs.  The syntax is:
          "orig-pkg" OrigName as NewName
      You can omit 'as NewName', in which case it is reexported as the same
      name.  Self referential aliases work too; however, they're only visible
      to packages which depend on this package.
      Left to future work: just provide a module name 'OrigName', where ghc-pkg
      figures out what the source package is.
