In my fantasy world, the `with` block would be tried again ;-) - if using cache-size-bytes, is the parameter that limits the number of objects by number ignored? It would be ideal to specify a size in bytes and an unlimited number of objects... - where can I find out more about invalidation-age? cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@... https://mail.zope.org/mailman/listinfo/zodb-dev |

No, even "non-persistent" caches persist for the length of the client process and have to be checked on reconnection. > Are those safe to use now? [1] They are much safer than they used to be. We're using them. We've had a couple of problems that I need to investigate.
