Apparently SourceForge's download link redirection does dynamic load balancing, so we potentially get a different URL each time:
Should figure out a way to stabilize that before we use this more widely... |

Motivation
Discord user "dan" pointed out that KSP2 mod
KSRe(frozen in KSP-CKAN/KSP2-NetKAN#174 after its author deleted it from SpaceDock) has been posting updates at https://sourceforge.net/projects/ksre/:https://sourceforge.net/projects/ksre/files/
Currently Netkan doesn't have the ability to crawl SourceForge, but while its API documentation looks quite inadequate, it does feature RSS-format (Really Simple Syndication, not Real Solar System) feeds for each mod's files:
https://sourceforge.net/projects/ksre/rss
Changes
Now a netkan with
$kref: '#/ckan/sourceforge/ksre'will be indexed from SourceForge based on its RSS feed. Each<item>with a title ending in.zipis taken to be a download, and the first one is treated as most recent.Retrieving and parsing the RSS feed went smoothly thanks to
System.ServiceModel.Syndication.SyndicationFeed, but getting a download URL was tricky because SourceForge thought our user agent string looked too browser-like and so wasn't returning redirects, so I had to pass in an alternate user agent string.Only a few fields can be set based on the minimal metadata in the feed, but luckily the
swinfo.jsonparser is able to handle the rest.
