What happened to rss.CacheParsedItemIDs #49

Closed zaddok closed 7 years ago

zaddok commented 7 years ago

My code no longer works. I assume this was changed recently. How do we reproduce this behaviour in the new versions?

See: https://gowalker.org/github.com/SlyMarbo/rss#CacheParsedItemIDs

I only remember I had to use this function to work around a bug I was encountering. I can't remember why exactly I was using it, it was a while ago now. It was likely to do with either running out of memory in a long running process, or to seeing updates to feeds coming through.

Hi,

The function is no longer necessary; caching is now automatic, so your code should continue to work the same way.

So this library no longer supports turning caching off? I really don't want tens of thousands of records collecting in memory over the course of the week... we probably have to start restarting the app every few days or create our own branch of this library.

If you don't want caching, simply use Fetch every time, rather than using Update after the first Fetch, but it's worth noting that the nature of RSS means that you'll probably get a lot of duplicate data.
