Technical
Currently
ia_import()
will twice query the (memcached) Internet Archive API during the process for importing from an Internet Archive ID.This PR passes the already-fetched
metadata
to the function that calls the metadata API again (get_marc_record_from_ia()
), thereby avoiding the second call to the (memcached) API.First, in "case 1", the metadata is gathered:
Once #8331 is merged, this will be the final query to the the IA metadata API, if that IA record has data in the
openlibrary_edition
field. ("Case 2".)However, if the IA record does not have data in
openlibrary_edition
, then there is a query for MARC data from the IA item, which callsget_marc_record_from_ia()
, which again calls the metadata API:This PR avoids that second query.
Testing
Verify already-fetch metadata is now passed into
get_marc_record_from_ia()
, and that IA imports still work as expected.Stakeholders
