I think it's changed again since 3.00. The --expiry option defaults to
four hours now; if the cache is older than that then it is refreshed.
(It's also refreshed if explicitly requested, or it doesn't exist.)
Hi Ralph
I don't think what is described in the v3.00 release notes was ever
implemented. I don't remember its ever working differently from the way you
describe. It does not appear to retrieve the whole of the this_week
schedule in one go. The most recent entry in my cache is 5 minutes before
the time of the refresh.
I always specify a very high --expiry option because I explicit refresh
the cache once each morning, without waiting for it to finish, and then
don't want it delay any of my later runs of get_iplayer during the day.
Thanks for reminding me about the --expiry option. Someone did tell me
about it a few months ago, but I couldn't remember what it was called and I
could not find it in the documentation. During the Proms I sometimes found
I had started to download the wrong Prom because an unexpected refresh had
changed the index numbers. I agree that it makes sense to set it to about a
month and I can then refresh under my control and when I want to.
Best wishes
Richard
