classmethod from_metadata(metadata: Dict[str, Any], url: str, filename: str) → swh.loader.package.deposit.loader.DepositPackageInfo

class swh.loader.package.deposit.loader.DepositLoader(url: str, deposit_id: str)

Bases: swh.loader.package.loader.PackageLoader[swh.loader.package.deposit.loader.DepositPackageInfo]

Load pypi origin’s artifact releases into swh archive.

visit_type = 'deposit'

get_versions() → Sequence[str]

Return the list of all published package versions.

Returns

Sequence of published versions

get_metadata_authority() → swh.model.model.MetadataAuthority

For package loaders that get extrinsic metadata, returns the authority the metadata are coming from.

get_metadata_fetcher() → swh.model.model.MetadataFetcher

Returns a MetadataFetcher instance representing this package loader; which is used to for adding provenance information to extracted extrinsic metadata, if any.

get_package_info(version: str) → Iterator[Tuple[str, swh.loader.package.deposit.loader.DepositPackageInfo]]

Given a release version of a package, retrieve the associated

package information for such version.

Parameters

version – Package version

Returns

(branch name, package metadata)

download_package(p_info: swh.loader.package.deposit.loader.DepositPackageInfo, tmpdir: str) → List[Tuple[str, Mapping]]

Override to allow use of the dedicated deposit client

build_revision(p_info: swh.loader.package.deposit.loader.DepositPackageInfo, uncompressed_path: str, directory: bytes) → Optional[swh.model.model.Revision]

Build the revision from the archive metadata (extrinsic artifact metadata) and the intrinsic metadata.

Parameters

• p_info – Package information

• uncompressed_path – Artifact uncompressed path on disk

Returns

Revision object

get_extrinsic_origin_metadata() → List[swh.loader.package.loader.RawExtrinsicMetadataCore]

Returns metadata items, used by build_extrinsic_origin_metadata.

metadata()

Returns metadata from the deposit server

load() → Dict

Load for a specific origin the associated contents.

for each package version of the origin

1. Fetch the files for one package version By default, this can be implemented as a simple HTTP request. Loaders with more specific requirements can override this, e.g.: the PyPI loader checks the integrity of the downloaded files; the Debian loader has to download and check several files for one package version.

2. Extract the downloaded files By default, this would be a universal archive/tarball extraction.

   Loaders for specific formats can override this method (for instance, the Debian loader uses dpkg-source -x).

3. Convert the extracted directory to a set of Software Heritage objects Using swh.model.from_disk.

4. Extract the metadata from the unpacked directories This would only be applicable for “smart” loaders like npm (parsing the package.json), PyPI (parsing the PKG-INFO file) or Debian (parsing debian/changelog and debian/control).

   On “minimal-metadata” sources such as the GNU archive, the lister should provide the minimal set of metadata needed to populate the revision/release objects (authors, dates) as an argument to the task.

5. Generate the revision/release objects for the given version. From the data generated at steps 3 and 4.

end for each

6. Generate and load the snapshot for the visit

Using the revisions/releases collected at step 5., and the branch information from step 0., generate a snapshot and load it into the Software Heritage archive
