newtype PackageCache index Source #
Cached information about packages in an index. We have a mapping from package name to a version map. Within the version map, we map from the version to information on an individual version. Each version has optional download information (about the package's tarball itself), and cabal file information. The cabal file information is a non-empty list of all cabal file revisions. Each file revision indicates the hash of the contents of the cabal file, and the offset into the index tarball.
The reason for each Version mapping to a two element list of
CabalHashes is because some older Stackage snapshots have CRs in
their cabal files. For compatibility with these older snapshots,
both hashes are stored: the first element of the two element list
being the original hash, and the (potential) second element with
the CRs stripped. [Note: This is was initially stored as a two
element list, and cannot be easily packed into more explict ADT or
newtype because of some template-haskell that would need to be
modified as well: the versionedDecodeOrLoad function call found
in the getPackageCaches function in PackageIndex.]
It's assumed that cabal files appear in the index tarball in the correct revision order.
