Library names, with Cabal submodule update
A library name is a package name, package version, and hash of the
version names of all textual dependencies (i.e. packages which were included.) A library
name is a coarse approximation of installed package IDs, which are suitable for
inclusion in package keys (you don't want to put an IPID in a package key, since
it means the key will change any time the source changes.)
- We define ShPackageKey, which is the semantic object which
is hashed into a PackageKey. You can use 'newPackageKey'
to hash a ShPackageKey to a PackageKey
- Given a PackageKey, we can lookup its ShPackageKey with
'lookupPackageKey'. The way we can do this is by consulting
the 'pkgKeyCache', which records a reverse mapping from
every hash to the ShPackageKey. This means that if you
load in PackageKeys from external sources (e.g. interface
files), you also need to load in a mapping of PackageKeys
to their ShPackageKeys so we can populate the cache.
- We define a 'LibraryName' which encapsulates the full
depenency resolution that Cabal may have selected; this
is opaque to GHC but can be used to distinguish different
versions of a package.
- Definite packages don't have an interesting PackageKey,
so we rely on Cabal to pass them to us.
- We can pretty-print package keys while displaying the
instantiation, but it's not wired up to anything (e.g.
the Outputable instance of PackageKey).
