The Xron product release is almost a year old, but Scheduler seems to be only available via CVS.
Can anyone comment as to the maturity/stability of these products? Any advice would be much appreciated.
I can't vouch for either of the products you mentioned, but I've had good luck with cron on linux teamed with wget :-) There doesn't seem to be much support in Zope for use cases where an action is not event driven, ie not a request/response pair. *** Vaporware Follows*** What *I* want, (but haven't written yet) is a product that can do continuous low level scraping of legacy data sources and feed this data into an RDBMS or the ZODB. A kind of "helper daemon". How each instance is scheduled would be one of many adjustable per instance config options :-) However, assuming that I do get around to building this product, I don't know where on the scale between ugly hack and elegant, reusable solution it will fall. This will also determine whether you ever see it on "zope.org" :-) Adam
