* pagestats: Class parameter can be used to override default class for
custom styling.
* pagestats: Use style=list to get a list of tags, scaled by use like
in a tag cloud. This is useful to put in a sidebar.
* Rework example blog front page.
The meta title data set by comments needs to be encoded the same way that
meta encodes it. (NB The security implications of the missing encoding
are small.)
Note that meta's encoding of title, description, and guid data, and not
other data, is probably a special case that should be removed. Instead,
these values should be encoded when used. I have avoided doing so here
because that would mean forcing a wiki rebuild on upgrade to have the data
consitently encoded.
For a while, I was avoiding capitalizing ikiwiki at the beginning of a
sentence. I now think that's a bad idea (unless explicitly referring to
the `ikiwiki` command). Still, I don't go all the way and always cap it,
as a proper noun. That would make the logo look bad. ;)
I also tend to avoid capping it as IkiWiki, except when referring to the
perl internals, which do use that capitalization. (Too late to change
that.) However, it's also reasonable to do so in a WikiLink, as a nod to
historical camelcase wikis.
Colons are not allowed at the start of urls, because it can be interpreted
as a protocol, and allowing arbitrary protocols can be unsafe
(CVE-2008-0809). However, this check was too restrictive, not allowing
use of eg, "video.ogv?t=0:03:00/0:04:00" to seek to a given place in a
video, or "somecgi?foo=bar:baz" to pass parameters with colons.
It's still not allowed to have a filename with a colon in it (ie
"foo:bar.png") -- to link to such a file, a fully qualified url must be
used.
Since Firefox version 3, it's done aggressive caching of visited pages, and
does not, by default, check if the cached content is still valid when
reloading or revisiting a page. By default, Firefox seems to not re-contact
the web server at all. Compare with eg, Epiphany and Chromium, which appear
to always check, and get back a 304 when the page is unchanged.
This header makes Firefox do the right thing, at least for html files. It
still over-caches if css, javascript, images, etc, are changed.
The info is stored in the session database, not the user database.
There should be no reason to need it when a user is not logged in.
Also, hide the email field in the preferences page for openid users.
Note that the email and username are not yet actually used for anything.
The email will be useful for gravatar, while the username might be used
for a more pretty display of the openid.
