I'm having a problem storing infinity. The following code reproduces
the problem on w2k:
from ZODB import FileStorage, DB
from persistent import Persistent
from persistent.mapping import PersistentMapping as dict
import transaction
storage = FileStorage.FileStorage('zodb.db')
db = DB(storage)
conn = db.open()
root = conn.root()
try:
root['data'] = 1e99999999
finally:
transaction.commit()
conn.close()
db.close()
storage.close()
Traceback (most recent call last):
File "test/test_zodb.py", line 14, in ?
