This patch uses the new record_strip_nonxml routine to attempt to display
the record when it contains invalid characters
Rather than silently strippg these, we warn in the logs, then add an 'about'
container to the response. It is displayed nicely in the web view or sent as "INVALID_METADATA" in
the xml response
The 'error' codes for OAI seem to be at the request level, and the offered codes don't have a match
for a bad record. Adding the about when we can recover seems the most generous response
To test:
Test plan, assumes using KTD default data - otherwise you need to find and import a record with encoding issues:
1 - Enable OAI-PMH system preference
2 - Browse to:
http://localhost:8080/cgi-bin/koha/oai.pl?verb=ListRecords&resumptionToken=marcxml/350////0/0/352
3 - 500 error:
Invalid data, cannot decode metadata object (biblio_metadata.id=368, biblionumber=369, format=marcxml, schema=MARC21, decoding_error=':8: parser error : PCDATA invalid Char value 31...
4 - Apply patch, restart all
5 - Reload the page
6 - It loads!
7 - Click 'Metadata' for record 369 - it succeeds!
8 - Check the logs - confirm you see a warning of the record problem
9 - Confirm 369 has an about section
10 - Check the individul 'GetRecord' response as well
