[repository] #1460066: backport datafeed cube as cubicweb source * add some attributes to CWSource to handle this kind of source (not natural to put everything in 'config' string). Adding a CWSource subclass has been attempted then rollbacked because it adds pain to handle multi-sources planning and it introduce an ambiguity on a generic relation (cw_source), which may be a penalty in multiple case * data feed sources are a new kind of source, namely 'copy based', which have no effect on the query planner * a data feed source is associated to a list of url and a parser (appobjects in the 'parsers' registry * entities imported by a data feed have cwuri set to their url on the distant site, their cw_source relation point to the data feed source, though their source stored in the entities table (returned by cw_metainformation) is their physical source, hence 'system'

from cubicweb import UnknownEid
source, = __args__

sql("DELETE FROM entities WHERE type='Int'")

ecnx = session.pool.connection(source)
for e in rql('Any X WHERE X cw_source S, S name %(name)s', {'name': source}).entities():
    meta = e.cw_metainformation()
    assert meta['source']['uri'] == source
    try:
        suri = ecnx.describe(meta['extid'])[1]
    except UnknownEid:
        print 'cant describe', e.__regid__, e.eid, meta
        continue
    if suri != 'system':
        try:
            print 'deleting', e.__regid__, e.eid, suri, e.dc_title().encode('utf8')
            repo.delete_info(session, e, suri, meta['extid'], scleanup=True)
        except UnknownEid:
            print '  cant delete', e.__regid__, e.eid, meta
