I just installed the AdaptableStorage product. When I try to upload a bigger File (File Product), it gives an error. I did not try to find the exact size, but 120 KB uploads OK, but 130 KB does not. So, maybe 128 KB? Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module OFS.Image, line 59, in manage_addFile Module OFS.Image, line 424, in manage_upload Module OFS.Image, line 501, in _read_data Module ZODB.Transaction, line 222, in commit Module ZODB.Transaction, line 195, in commit Module ZODB.Transaction, line 256, in _commit_objects Module Products.AdaptableStorage.zodb.ASConnection, line 153, in commit Module Products.AdaptableStorage.zodb.ASStorage, line 195, in new_oid Module Products.AdaptableStorage.mapper_std.PathKeychainGenerator, line 27, in makeKeychain AttributeError: 'None' object has no attribute 'startswith' The file does not upload. I used Zope2-filesystem mapping exactly from the doc.txt The same files to ordinary ZODB upload OK.
