Advogato Status Report

A new rev of mod_virgule code went live today. See the changelog for the details. Other than a few more bug fixes, the big change is the addition of a blog aggregator. This will allow Advogato users who keep their blog somewhere else to syndicate it here so it shows up in the recentlog. There are already seven users whose posts have returned to the recentlog. Hopefully more past Advogato users will follow.

Initially the aggregator supports Atom v1.0, RSS v0.91, v0.92, v2.0, and RDF Site Summary (sometimes known as RSS v1.0, a fork of "real" RSS). My recommendation is to use Atom v1.0 if you've got, with RSS v2.0 as a safe alternative. I expect there are still some bugs to work out, so bear with me for a week or so as we sort things out. There are a few known caveats:

  • Due to limitations in the existing recentlog code, bursts of multiple syndicated entries from the same user that arrive within a narrow time window will only result in one recentlog entry. This is only likely to be noticed the first time the feed is grabbed when maybe 5 or 10 entries get sucked in at once.
  • The blog post title, link, and original posting date are stored locally but the current diary code doesn't display them yet. The additional info should start showing up after the next code release. Soon...
  • Some variants of older RSS (v0.xx) feeds may produce unexpected results. There seem to be an endless number of variations of the RSS formats and I may not have accounted for them all yet.
  • RDF Site Summary format is more complex than Atom or RSS. It's a "modular standard" with dozens of different modules. Trying to parse the output of every conceivable combination of modules is non-trivial. Fortunately, this format isn't very common. Right now, I'm parsing a couple of combinations that use RDF Site Summary v1.0, plus the date tag from the Dublin Core module and the content encoding fields of the most recent draft version of the Content module. That's working for the one RDF Site Summary feed I know of on Advogato. If you can't use Atom or RSS and your RDF Site Summary feed doesn't work, send me a link and I'll try to support it.
  • It will be safer to either to use Advogato for blogging or syndicate your blog here from another site. Mixing the two options, while possible, may produce unexpected results with regard to the ordering of the posts if you post multiple times per day.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
