rss2 feeds times-out in miro/itunes/firefox

Who will test this:


In Miro, iTunes and Firefox rss2 feeds load very slowly and often timing out. listSyndicatableContent inside from qRSS2Syndication

It seems it loads all actual objects from the brains, ie it unpickles objects from the zodb, instead of just using the catalog search result object (the brain)

FYI RSS1 loads fine.

The solution would be, of course, to stop waking up items while rendering the page. the only obvious way is to add the infos into the metadatas' of the plone catalog.

As Anna recommended, I had a look at It works on plone3 and could have provided a solution (at least for the plone3 plumi) but.. no. It wakes every objects served also. Creepy. I guess we'll have to work on a policy of catalog metadatas. If critical, we could propose a new zcatalog (feeding catalog) that would contain only the needed info. Any idea, andycat ?

just upping the importance of this one even though I know people know about it as EM vodcast feeds have been broken for a few months now.

might be a solution

and the start of the transmission metadata impl

comment:5 Changed 10 years ago by andycat

Ive just noticed that the /RSS view , that is rss 1 wakes up objs form the catalog too! Inside the the ContentLicensing template we are using which we use in


I guess we didnt notice because we are mainly using rss2 feeds to download the videos..

This tag specifies the artwork for your podcast. Put the url to the image in the href attribute. iTunes prefers square .jpg images that are at least 300 x 300 pixels, which is different than what is specified for the standard RSS image tag.

iTunes supports images in JPEG and PNG formats. The url must end in ".jpg" or ".png". If the itunes:image tag is not present, iTunes will use the contents of the RSS image tag.
