How to include work-level-rels in web service API for a large release?

cngcng · February 7, 2021, 1:06am

I set up a local musicbrainz-docker server, to tag classical music file using Picard & classical Extra.
If a release has many tracks or media (I’m not sure what is the constraint), the web service API doesn’t include work in the API response.
For example,
http://musicbrainz.org/ws/2/release/788e89aa-10a5-4524-bcfb-bcbf92d10a27?inc=release-groups+media+discids+recordings+artist-credits+artists+aliases+labels+isrcs+collections+artist-rels+release-rels+url-rels+recording-rels+work-rels+recording-level-rels+work-level-rels

This response doesn’t have work relationship in the recording.
How can I change this to include work relationship, even if a release has a large track count?
I mean, changing my own local server setting.

Regards.

Hi!

You want to change this number, or change the code to not set a max:

github.com

metabrainz/musicbrainz-server/blob/f8bd7e9366eb6e836dfcee9b626e1ca969db1c4f/lib/MusicBrainz/Server/Controller/WS/2/Release.pm#L150


      
          my $inc_artist_credits = $inc->artist_credits;
          if ($inc_artist_credits) {
              push @ac_entities, @tracks, @recordings;
          }
          
          # The maximum number of recordings to try to get relationships for, if
          # inc=recording-level-rels is specified. Certain releases with an enourmous
          # number of recordings (audiobooks) will almost always timeout, driving up
          # server load average for nothing. Ideally we can remove this limit as soon as
          # we resolve the performance issues we have.
          my $max_recording_relationships = 500;
          
          if ($inc->recording_level_rels && @recordings <= $max_recording_relationships) {
              push @rels_entities, @recordings;
          }
          
          # Disable artist-credits during linked_recordings, since we load
          # them below together with the tracks and release.
          $inc->artist_credits(0) if $inc_artist_credits;
          $self->linked_recordings($c, $stash, \@recordings);
          $inc->artist_credits(1) if $inc_artist_credits;

Hi.

I increased the size to 3000. I confirmed the server response includes the work relations for the previous example.

Thanks.
