[sfWiki-devel] info.php3

[Todd L. M. <tm...@ha...>]

	Should saving a WikiTopic* update all pages links-to-me field?  
Pros: the info.php3 page could be pre-rendered.  Cons: it will take a long
time, and probably require some locking to handle contention
properly.  (That is, we could end up in a situation where every other
topic in the database reflects one edit, and the other half a different
edit.)  It will also require additional space in the database.  The
info.php3 could not be pre-rendered; in fact, neither could the
links-to-me field.  (Thought it may be worthwhile to cache the list
anyway, checking for 'expiration'; this would require another field in the
database, however.)

	That being said, the infastructure for links-to-me (requires
links-from-me field) is in place.  (Though the 'elegant' solution I came
up with for it involves the 'tag' <wikitopic TopicName /wikitopic>!  I
chose not to remove the tags from the final rendered version, in case they
become handy later on :))  This, in turn, means that it will be easy to
determine orphan status, and hub/node lists.**  Furthermore, because the
pre-rendering code includes auto-timestamping, the most-recently-changed
list ought to be fairly simple to generate.

Which brings up the question of generating the global information page.  
I think once-a-day (e.g. by cron) or from the admin pages on-demand is a
good way to go about it; on-the-fly generation will be rather expensive,
and there's probably not a good way to pre-render/cache it -- every edit
would have update things, which would get messy.
