Software Heritage Base Loader

Software Heritage - Loader foundations

The Software Heritage Loader Core is a low-level loading utilities and helpers used by :term:loaders <loader>.

The main entry points are classes:

• :class:swh.loader.core.loader.BaseLoader for VCS loaders (e.g. svn)
• :class:swh.loader.core.loader.DVCSLoader for DVCS loaders (e.g. git, ...)
• :class:swh.loader.core.loader.ContentLoader for Content loader
• :class:swh.loader.core.loader.DirectoryLoader for Directory loader
• :class:swh.loader.package.loader.PackageLoader for Package loaders (e.g. PyPI, Npm, ...)
• ...

Package loaders

This package also implements many package loaders directly, out of convenience, as they usually are quite similar and each fits in a single file.

They all roughly follow these steps, explained in the :py:meth:swh.loader.package.loader.PackageLoader.load documentation. See the :ref:package-loader-tutorial for details.

VCS loaders

Unlike package loaders, VCS loaders remain in separate packages, as they often need more advanced conversions and very VCS-specific operations.

This usually involves getting the branches of a repository and recursively loading revisions in the history (and directory trees in these revisions), until a known revision is found
