[Parse compiler field from old config files correctly
Duncan Coutts <duncan@haskell.org>**20090116002851
 Really old versions of cabal-install generated a default config
 containing "compiler: GHC". Sadly the new way we generate the
 config file parser from the command line parser means we end up
 with a case-sensitive parser as it only matches the exact
 command line flags. So we hack it and add in a traditional
 parser for that field only. Really the command line and config
 file infrastructure needs rewriting again. Sigh.

[Use a more precise package substitution test in improvePlan
Duncan Coutts <duncan@haskell.org>**20081219215922
 This is where we take a valid plan and we "improve" it by swapping
 installed packages for available packages wherever possible. This
 change is to the condition we use in deciding if it is safe to use
 the installed package in place of a reinstall. Previously we checked
 that the dependencies of the installed version were exactly the same
 as the dependencies we were planning to reinstall with. That was
 valid but rather conservative. It caused problems in some situations
 where the installed package did not exactly match the available
 package (eg when using development versions of a package or of ghc).
 What we do now is test if the extra constraints implied by selecting
 the installed version are consistent with the existing set of
 constraints. This involves threading the constraint set around. In
 theory this should even cope with adding additional packages to the
 plan as a result of selecting an installed package.
] 
[Use installed constraints instead of hiding versions of the base package
Duncan Coutts <duncan@haskell.org>**20081219193740
 We want to stop cabal-install from accidentally trying to upgrade
 the base package since this doesn't work in most cases. We used to
 achieve that by deleting the base package from the available package
 index. We now do it by leaving the package index as is and instead
 adding a constraint that we pick only an installed version of base.
 This is a nicer hack and has the potential to give better error
 messages.
] 
[Extend the invariant on the Constraints ADT
Duncan Coutts <duncan@haskell.org>**20081219192309
 It now carries around the original version of the database
 purely so that it can do a much more extensive consistency
 check. Packages are never gained or lost, just transfered
 between pots in various slightly tricky ways.
] 
[Fix constraint set handling for installed constraints
Duncan Coutts <duncan@haskell.org>**20081219182328
 A rather subtle bug. The code was actually correct but the transitionsTo
 assertion was not accounting for a transition between the case where
 a package's available version had been excluded and then the whole thing
 got excluded by a version constraint. It counted one side as a loss
 without a corresponding gain on the other side.
] 
[Add a install/upgrade --preference='foo < 2' flag
Duncan Coutts <duncan@haskell.org>**20081218213849
 This behaves just like the preferred-versions file in the hackage index

[Fix selecting paired packages
Duncan Coutts <duncan@haskell.org>**20081007062930
 Previously when we selected base 4 (and as a consequence
 slected base 3 too) we didn't properly trace the dependencies
 of base 3 so if nothing actually required base 3 then we ended
 up with base 3 in the solution but not with syb which it
 depends on. Consequently the solution was invalid.
 Now we select the paired package properly (hopefully).

[Take preferred versions into account in dependency planning
Duncan Coutts <duncan@haskell.org>**20081006055129
 This means we can now globally prefer base 3 rather than 4.
 However we need to be slightly careful or we end up deciding
 to do silly things like rebuild haskell98 against base 3.
 That would happen because the h98 package doesn't constrain
 the choice to one or the other and we would prefer base 3.
 So we have to add that we really prefer whatever it uses
 currently (if any).

[When finalising paired packages, cope with there being multiple choices
Duncan Coutts <duncan@haskell.org>**20081005053821
 For ordinary packages we selected a single version which means
  we added an equality constraint. As a consequence we used to
 assume there was only one version left when finalising. For
 paired packages there may be two versions left if the package
 did not directly constrain the choice to just one. If there is
 more than one version remaining then we have to pick between
 them. At the moment we still pick the highest version, but
 later we can take a global preference or polciy into account.

 The trick is that when applying constraints to paired

 would only exclude one then we discard the constraint.

 version depends on the other.

 of the same package that that excludes, and not the other packages
 we exclude by applying the dependency constraints of the selected
 package. In future we would like to do that so we now report the
 package name of discards not just the version. Though we do group
 by the package name to avoid too much repition.
