Tue May 6 17:02:09 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Check that InstallPlan dependencies respect a state relation For example it's not allowed for installed packages to depend on configured packages.

patch applied (cabal-install): Hide the installed instance when installing the local package.

06 May '08

Tue May 6 06:32:36 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Hide the installed instance when installing the local package. Otherwise the dependency resolver may decide to pick the installed instance of the package but we really do want to install the local version. So to remove that choice from the dep resolver we just delete it from the installed package index.

patch applied (cabal-install): Add more info and debug messages at key parts of the install process

patch applied (cabal-install): Switch from DepGraph to InstallPlan
by Duncan Coutts 06 May '08

06 May '08

Mon May 5 02:17:43 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Switch from DepGraph to InstallPlan The dependency resolver has had to be extended in a slightly hacky way to gather the extra information needed by an install plan. In particular it requires the flags to use to configure each package, the actual versions of dependencies to use and all of the installed packages and their closure of dependencies. However the current resolver is fairly naive and so can be easily persuaded into producing an invalid install plan, in which case you'll get a detailed list of reasons as to why it is invalid.

patch applied (cabal-install): Improve InstallPlan error checking and reporting
by Duncan Coutts 06 May '08

06 May '08

Sun May 4 13:18:57 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Improve InstallPlan error checking and reporting Instead of just reporting that a plan is invalid, produce a detailed list of reasons why it is invalid. This should be useful for people debugging dependency resolvers. Also rename the complete property to closed, since the property is about the set being closed under the dependency relation. Also re-use the PackageIndex functions for checking the validity conditions rather than re-implementing the checks locally.

patch applied (cabal-branches/cabal-1.4): Add PackageIndex.reverseDependencyClosure
by Duncan Coutts 06 May '08

06 May '08

Tue May 6 16:49:02 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Add PackageIndex.reverseDependencyClosure It's similar to dependencyClosure but looks at reverse dependencies. For example it's useful to find all packages that depend on broken packages and are thus themselves broken.
