When responding to ListRecords and ListIdentifiers verbs, OAI server doesn't
return proper resumption token. At the end of a result set, OAI server
generates a resumption token even if there isn't anymore records. Consequently,
OAI harverster will send a new request, based on this invalid resumption,
token. OAI Server responds with an empty resultset, which is considered as an
invalid response by most of the harvesters.
TO TEST:
- Find in your DB, a day where a few biblio records have been created. The
number of created biblios must inferior to OAI-PMH:MaxCount.
- Let say this day is 2014-01-09. Send an OAI-PMH request to Koha OAI Server:
/cgi-bin/koha/oai.pl?verb=ListRecords&metadataPrefix=marcxml&from=2014-01-09&until=2014-01-09
- At the end of the result, you will see a resumption token which looks like that:
<resumptionToken cursor="47">marcxml/47/2014-01-09/2014-01-09/</resumptionToken>
This is wrong. No resumptiion token should be sent since there isn't anymore
records to harvest.
- Apply the patch.
- Resend the OAI-PMH request. There is no resumption token at the end of the
result.
- You could test also with ListIdenfiers verb in place of ListRecord.
