ddblabs-ometha's Issues

Fehler beim Harvesten der OAI Schnittstelle der BSB (MARC)

Das Harvesten der OAI-Schnittstelle der Bayerische Staatsbibliothek (BSB) für MARC-Daten scheitert mit neueren Versionen von Ometha. Mit anderen OAI-Schnittstellen treten die u. g. Fehler nicht auf.
Mit z. B. Ometha 1.8.2 (Windows, exe) funktoniert das Harvesten der BSB-OAI-Schnittstelle.

Alle Beispielaufrufe verwenden die folgende Konfiguration:

BSB_m21.yaml

name: BSB_m21
baseurl: http://bdr.oai.bsb-muenchen.de/OAIHandler
metadataPrefix: MarcXchange
datengeber: BSB
set:
   - all
fromdate: null
untildate: null
timeout: 4
outputfolder: BSB_m21
debug: false
lazy: false
numberofprocesses: 2

Der Aufruf ist jeweils
ometha conf -c BSB_m21.yaml

Ubuntu über SSH (Ometha 1.9.5) schläg fehl:

connectionpool.py 836 urlopen
retries = retries.increment(method, url, response=response, _pool=self)

retry.py 574 increment
raise MaxRetryError(_pool, url, error or ResponseError(cause))

urllib3.exceptions.MaxRetryError:
HTTPConnectionPool(host='bdr.oai.bsb-muenchen.de', port=80): Max retries exceeded with url: /OAIHandler (Caused by ResponseError('too many 500 error responses'))

--------------------------------------------------------------------------------------------------------------------------
ometha 8 <module>
sys.exit(main())

__init__.py 252 main
session.get(baseurl, verify=False, timeout=(20, 80))

sessions.py 542 get
return self.request('GET', url, **kwargs)

sessions.py 529 request
resp = self.send(prep, **send_kwargs)

sessions.py 645 send
r = adapter.send(request, **kwargs)

adapters.py 510 send
raise RetryError(e, request=request)

requests.exceptions.RetryError:
HTTPConnectionPool(host='bdr.oai.bsb-muenchen.de', port=80): Max retries exceeded with url: /OAIHandler (Caused by ResponseError('too many 500 error responses'))

Ein entsprechender Aufruf mit Curl funktioniert und liefert die ersten Identifier:

curl -G -d "verb=ListIdentifiers" -d "metadataPrefix=MarcXchange" -d "set=all" http://bdr.oai.bsb-muenchen.de/OAIHandler

Der Aufruf mit Ometha 1.9.6 (exe) unter Windows schlägt ebenfalls fehl:
