>Subject: [PATCH] Bug 38416: Failover to MARCXML if cannot roundtrip USMARC
> during indexing
>
>This change failsover to MARCXML from USMARC if there are any
>warnings generated by MARC::File::USMARC::decode when trying to
>roundtrip the record.
>
>Test plan:
>0. Apply the patch
>1. Setup your koha-testing-docker to use Elasticsearch
>2. Create a new record with 15,000 characters in the 500$a field
>3. Index that record
>(e.g. perl misc/search_tools/rebuild_elasticsearch.pl --biblios -v -v)
>4. Note that a warning saying the following appears:
>"Warnings encountered while roundtripping a MARC record to/from USMARC.
>Failing over to MARCXML"
>5. View the "Elasticsearch record" on the detail page and note that the
>marc_format is MARCXML
>6. Perform a search for the record (the keyword should be something that
>brings up other results too)
>7. Note that the record appears correctly in the search results
