rejected_origins: List[RejectedOrigin]#: List of origins rejected by the lister.

class swh.lister.save_bulk.lister.SaveBulkLister(url: str, instance: str, scheduler: SchedulerInterface, credentials: Dict[str, Dict[str, List[Dict[str, str]]]] | None = None, max_origins_per_page: int | None = None, max_pages: int | None = None, enable_origins: bool = True, per_page: int = 1000, max_workers: int = 4)[source]#

Bases: Lister[SaveBulkListerState, List[SubmittedOrigin]]

The save-bulk lister enables to verify a list of origins to archive provided by an HTTP endpoint. Its purpose is to avoid polluting the scheduler database with origins that cannot be loaded into the archive.

Each origin is identified by an URL and a visit type. For a given visit type the lister is checking if the origin URL can be found and if the visit type is valid.

The HTTP endpoint must return an origins list in a paginated way through the use of two integer query parameters: page indicates the page to fetch and per_page corresponds the number of origins in a page. The endpoint must return a JSON list in the following format:

[
    {
        "origin_url": "https://git.example.org/user/project",
        "visit_type": "git"
    },
    {
        "origin_url": "https://example.org/downloads/project.tar.gz",
        "visit_type": "tarball-directory"
    }
]

The supported visit types are those for VCS (bzr, cvs, hg, git and svn) plus the one for loading a tarball content into the archive (tarball-directory).

Accepted origins are inserted or upserted in the scheduler database.

Rejected origins are stored in the lister state.

LISTER_NAME: str = 'save-bulk'#

state_from_dict(d: Dict[str, Any]) → SaveBulkListerState[source]#: Convert the state stored in the scheduler backend (as a dict), to the concrete StateType for this lister.

state_to_dict(state: SaveBulkListerState) → Dict[str, Any][source]#

Convert the StateType for this lister to its serialization as dict for storage in the scheduler.

Values must be JSON-compatible as that’s what the backend database expects.

get_pages() → Iterator[List[SubmittedOrigin]][source]#

Retrieve a list of pages of listed results. This is the main loop of the lister.

Returns:: an iterator of raw pages fetched from the platform currently being listed.

check_origin(origin_url: str, visit_type: str) → ListedOrigin | RejectedOrigin[source]#

get_origins_from_page(origins: List[SubmittedOrigin]) → Iterator[ListedOrigin][source]#

Extract a list of model.ListedOrigin from a raw page of results.

Parameters:: page – a single page of results
Returns:: an iterator for the origins present on the given page of results
