Alexis Metaireau <ale...@notmyidea.org> added the comment: Attaching a work in progress file which intend to replace the current install.py file. The implementation isn't finished yet but the overall design is here.
It comes with four classes: - Installer which manages the overall installation procedure. It shares a distribution cache with the dependency handler so distributions are not downloaded / extracted multiple times. The installer is able to install / remove single distributions OR distributions with their dependency tree. - DependencyHandler which takes care about getting the dependencies from either the metadata stored in the indexes or inside the distirbutions. - The DistributionCache class is just a store containing the location of the distributions that had been extracted/downloaded. It provides methods to ease the work with them (so any external user don't need to care about the state of the distribution when requesting it). - DirectoryMover provides a way to deal with moving/deleting operations with a commit/rollback API. The goal is to simplify a lot the current API and to provide a reusable tool for other installers. why not putting this in shutil at some point. This file is provided here mostly for feedback, but the work is not finished yet. ---------- Added file: http://bugs.python.org/file25831/install.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14950> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
