commit ba303f946ecd3e15e58de0072ce71b50aa423d59
Author: Nicolas Dandrimont <nicolas@dandrimont.eu>
Date:   Thu Jan 21 17:31:43 2021 +0100

    grab_next_visits: don't re-schedule visits too fast
    
    The earlier implementation would just schedule new visits for origins
    forever, regardless of whether they were already scheduled or not.

commit 808ae6851faee9b633e773f9150d360cdb927146
Author: Nicolas Dandrimont <nicolas@dandrimont.eu>
Date:   Thu Jan 21 17:29:45 2021 +0100

    Allow overriding the timestamp of grab_next_visits
    
    This makes the simulator behavior more consistent with reality.

Author: Nicolas Dandrimont <nicolas@dandrimont.eu>

    simulator: add simple lister simulation

commit 1f1aad459c4b0740ecbe96e9809e4b31f66bf999
Author: Valentin Lorentz <vlorentz@softwareheritage.org>
Date:   Thu Jan 21 14:54:53 2021 +0100

    Factor out ListedOrigin generation to use the OriginModel
    
    This generates consistent last_update values according to the model and
    simulated time.

commit b93aa5be2c2d5dc2130e1027698f3e1255052d8d
Author: Valentin Lorentz <vlorentz@softwareheritage.org>
Date:   Thu Jan 21 13:01:53 2021 +0100

    Make PaginatedListedOriginList a concretization of PagedResult
    
    1. consistent with swh-storage and swh-indexer-storage
    2. we can use swh.core.api.classes.stream_results on scheduler.get_listed_origins.

commit 2f47936731cf438a5195978a2af3250597b693b5
Author: Nicolas Dandrimont <nicolas@dandrimont.eu>
Date:   Wed Jan 20 17:29:16 2021 +0100

    Add scheduling policy for already visited origins with known last update
    
    This policy schedules origins by decreasing order of "visit lag" (that
    is, origins with the most lag are scheduled first).

commit acad712ad3f71f88f99e45e9b4f571ad751945dc
Author: Nicolas Dandrimont <nicolas@dandrimont.eu>
Date:   Wed Jan 20 17:25:46 2021 +0100

    Add scheduling policy for never visited origins
    
    This policy orders never visited origins by increasing date of last
    update (scheduling the "oldest" never visited origins first).

See https://jenkins.softwareheritage.org/job/DSCH/job/tests-on-diff/234/ for more details.
