Module CPM.Repository.CacheFile
This module contains operations implementing a file-based repository cache
for faster reading the repository. This file-based implementation
is used if the command sqlite3
is not available (compare module
CPM.RepositoryCache.Init).
The repository cache contains reduced package specifications
for faster reading/writing by removing some information
which is not relevant for the repository data structure.
The relevant package fields are:
- small cache: name version dependencies compilerCompatibility
- large cache: synopsis category sourceDirs exportedModules executableSpec
