the [[plugins/aggregate]] plugin mashes the `title` of an aggregated post into a filename. This results in long filenames. I have hit a filesystem length limitation on several occasions. Some (ab)uses of RSS, e.g., twitter, generate long titles. Especially once you throw escaping into the mix: $ ikiwiki --setup testsetup --aggregate --refresh failed to write ./test/lifestream/Hidden_Features_Of_Perl__44___PHP__44___Javascript__44___C__44___C++__44___C__35____44___Java__44___Ruby___46____46____46__._aggregated.ikiwiki-new: File name too long aggregation failed with code 9216 $ echo $? 25 It would also appear this abrubtly terminates aggregate processing (if not ikiwiki itself). Only after moving my test repo to `/tmp` to shorten the filename did I see newer RSS feeds (from a totally different source) picked up. -- [[Jon]] > I have to wonder what filesystem you have there where 147 characters > is a long filename.
