This is all because LiveJournal has undocumented size limits on incoming syndication feeds, limits that DWiki can easily blow past. Since I actually wanted LiveJournal to be able to get syndication feeds from me, DWiki has grown two new configuration settings.
feed-max-size is an integer kilobytes. It is a rough limit on how
large any feed can be; once DWiki generates a feed that is this many
kilobytes or larger it stopps adding more entries, regardless of the
atomfeed-display-howmany. If unset, there is no size
feed-max-size to the whitespace
separated list of IP addresses or tcpwrappers style IP address
prefixes (eg '
66.150.15.' to get all of
Syndication fetches from other addresses will behave as if there was
feed-max-size limits only the size of the
atom::comments output to that size. Whatever else
is tacked on to make up a feed (hopefully not very big) will add some
feed-max-size a bit. For LiveJournal, the limit is
apparently 150 kilobytes (currently), so setting it to '120' or so
should provide a comfortable safety margin.
Although I'm not entirely fond of this (to put it one way), the documentation has been updated appropriately, making this feature more or less official.
