The fix involved embedding the session id in the forms, and not allowing the
forms to be submitted if the embedded id does not match the session id.
In the case of the preferences form, if the session id is not embedded,
then the CGI parameters are cleared. This avoids a secondary attack where the
link to the preferences form prefills password or other fields, and
the user hits "submit" without noticing these prefilled values.
In the case of the editpage form, the anonok plugin can allow anyone to edit,
and so I chose not to guard against CSRF attacks against users who are not
logged in. Otherwise, it also embeds the session id and checks it.
For page editing, I assume that the user will notice if content or commit
message is changed because of CGI parameters, and won't blndly hit save page.
So I didn't block those CGI paramters. (It's even possible to use those CGI
parameters, for good, not for evil, I guess..)
The only other CSRF attack I can think of in ikiwiki involves the poll plugin.
It's certianly possible to set up a link that causes the user to unknowingly
vote in a poll. However, the poll plugin is not intended to be used for things
that people would want to attack, since anyone can after all edit the poll page
and fill in any values they like. So this "attack" is ignorable.

* meta: To support the pagespec functions, metadata about pages has to be

* Fix encoding bug when pagestate values contained spaces.
The customary 2.5 hours of staring at random css turtorials later, here
is a pure css latout for the static recentchanges page that, while not as good
as the old table layout, it decent. And it works well in lynx. And
should generate some pretty nice rss too.
- add a title to the editpage form;
- pass a reference to the list of buttons to the formbuilder_setup
hooks, so we can add ours;
- relax asumption about the possible submit values (use "Save Page"
explicitly);
- de-hardcode the submit buttons from the editpage template
(This was needed for compatability with a bug in CGI::FormBuilder
3.0401, but ikiwiki already needs a newer version.)
* Pass buttons to all other formbuilder_setup hooks too.

* The patch also adds dcterms:creator to rss items that have a known author.
ESCAPE=HTML for titles in the templates for these feeds, and instead
escape the title going in to the template. Previously, the title was
sometimes double-escaped in a feed (if set via meta title), and sometimes
not (if set from the page filename).
* In the meta plugin, when a title is set, encode the html entities in it
numerically. This works better in the current landscape of a rss spec that
doesn't specify encoding, and variously broken feed consumers, according
to <http://www.rssboard.org/rss-profile#data-types-characterdata>.

you'll want to rebuild wikis on upgrade to this version to avoid
inconsistencies.

there.
