After intermittently thinking about this for a few
days, let me see
if I understand what's going on.
1) When I import any new page via importDump, it gets parsed and
saved in the parser cache.
2) During this parsing, the magic word {{SERVER}} looks for $_SERVER
and finds 'localhost' instead of my base url.
3) When I click on the page without editing, it calls that cached
version, which includes localhost instead of
mywiki.org or whatever.
All the other new content is already there because it was generated
at the same time as the incorrect value of {{SERVER}}.
Yep.
I had
foolishly thought that there was some kind of separate caching of
templates magic words (doh).
Nope. :)
4) When I do any kind of edit from the web interface,
it reparses the
page and saves the new version in the cache, but now it correctly
interprets {{SERVER}}.
Yep.
Is that right? If so, am I correct that:
- Temporarily disabling caching during import won't help
Well, you could disable the parser cache I guess...
- setting $wgServer will work, but only if I set it
somewhere where
it won't be reset to localhost by importDump. i.e. I should set it in
AdminSettings.php?
LocalSettings.php would be an appropriate place.
- {{SERVER}} will get confused either way if I have
different URLs
pointing to the same wiki? In my case, I have
ecoliwiki.org,
ecoliwiki.net, and
ecoliwiki.com. To fix this, I should do some
rewrite rules.
The system generally expects that you'll only deal with one canonical
URL and isn't currently really set up to handle multiple access points
that aren't done by redirects.
You could do some tweaking with the parser cache user config hash key if
you're careful; see extensions/RenderHash.php for an example; you'd set
something based on the alternate access route being used.
