23e9c6beb2 Use AssetTagHelpers in S5 Template
Otherwise S5  breaks when Instiki is
deployed to a non-root URL (e.g., by
setting RailsBaseURI in Passenger).

Also a stylistic tweak in lib/node.rb

There's a moderate efficiency gain to be had by
using Set#include?, rather than Array#include?

3ff68ef42f Don't Expand NCRs
That operation is not idempotent (among other defects).
Instead, just check that the NCRs corespond to valid utf-8.

116255dc0d Purify Categories
Apply the same methodology, as in Revision 432,
to the category chunk-handler. This completes
the replacement of all the code that looks like

  if string.is_utf8?
    do something
  else
    complain
  end

with code that looks like

  string.purify
  do something

c79fef9c01 Clean, rather than Complain
Previously, if the user tried to submit content which was
malformed utf-8, Instiki would complain loudly to him.

A slightly more user-friendly approach was suggested by
the latest Rails 2.3.4, and a conversation with Sam Ruby
(who suggested some improvements).

Now, instead of complaining, we remove the offending bytes,
leaving a well-formed utf-8 string, which we pretend is what
the user meant to submit.

d7832ba262 Wiki Redirects and Page Renaming
Added the ability to rename existing pages.
[[!redirects Some Page Name]] redirects Wikilinks [[Some Page Name]] to
  the current page (assuming "Some Page Name" does not exist).
  Real pages trump redirects (though this may change, depending on 
  user feedback).

8ea8b6a8f7 <video> and x-sendfile
Using <object> and <embed> were forbidden for obvious
security reasons. Instiki now permits embedding video
via the HTML5 <video> element (Ogg/Theora encoded videos
only, with .ogg or .ogv extensions). You can even upload
videos with

    [[foo.ogg:video]]

Instiki now support x-sendfile. See the Proxying page for
configuring Apache (with the x-sendfile module). Lighttpd
should work similarly.

Update Rails to latest Edge (hopefully converging on RC2!).

133c21b801 Bugfixes and Rails Edge
Update to Rails 2.3.1.
  (Actually, not quite. Doesn't look like 2.3.1 will be released
   today, but I REALLY want to push these bugfixes out.)
Removed bundled Rack (Rails 2.3.1 comes bundled with Rack 1.0).
Add
     config.action_view.cache_template_loading = true
  to production environment.
Fix FastCGI bug (http://rubyforge.org/tracker/index.php?func=detail&aid=24191&group_id=186&atid=783).
Fix WikiWords bug (http://rubyforge.org/pipermail/instiki-users/2009-February/001181.html).

5d15e3f39d Security: Instiki 0.16.2
On Webs with file uploads enabled, uploaded files were stored
(in version 0.16.1 and earlier) in the public/ directory.

This was a security threat. A miscreant could upload a .html file.
When a user clicked on the link to the file, it was opened (unsanitized)
in the browser.

As of version 0.16.2, uploaded files are stored in the webs/
directory. Now, when the user clicks on the link, the file is sent
with the

    Content-Disposition: attachment

header set, which causes the file to be downloaded, rather than opened
in the browser. As always, files downloaded from the internets should be
treated with caution. At least, this way, they are not aoutomatically 
opened in the browser.

To move your existing uploaded files to the new location, do a

     rake upgrade_instiki

0b2a6935a2 Export XHTML Pages
When a Web uses one of the Markdown Text Filters, and you export
all the pages as a zip file, you'd like the MathML and SVG to
render when the pages are viewed locally. This means saving them
with a .xhtml extension. Users of non-XHTML-capable browsers or
Textile users should still get .html files.

13b7e1d766 A Real Fix For the "Backslashes in Included Equations" Bug
Ruby's String.sub!(pattern, replacement) routine is fundamentally

294ac909c4 Don't hide equations, except in MarkdownMML and MarkdownPNG
In other engines, e.g. textile, the equation delimiters have no
special meaning. So they should not be used to hide content from
wiki processing.

074711d4c5 Hide Equations From WikiChunk Processing
WikiWord (and the like) could wreak havoc in equations. Protect them
(the way <a>, <pre> and <code> blocks are protected).

For some reason, this doesn't seem to work in inline equations.

82e7aa52c7 Referring Pages for File List
For the file_list  action, include the pages which link to the given file(s).
This required rejiggering so that that information is actually retained in the database.
Unfortunately, you'll actually need to revise the page(s) in question, because that's the
only time this information is updated in the database.

52c1f74ecc Add a couple of XSS tests.
Some more tests from Clint Ruoho. The main branch of Instiki (and, I guess,
the old sanitizer) are vulnerable.

Also: under Ruby 1.8.x, CGI.unescapeHTML screws up horribly decoding NCRs
which represent high-bit ASCII characters. UTF-8 agrees with 7-bit ASCII,
but CGI.unescapeHTML doesn't seem to know that they disagree for i>127.

3a109d1c82 Thread Safety
Use "Thread.current[:included_by]" instead of  the Class variable,
"@@included_by".

The former will work on some newfangled multi-threaded Webserver stack,
which uses separate threads to handle multiple simlutaneous requests
(one request/thread). Dunno that the rest of the application is
thread-safe, but using a class variable, in this context, probably isn't.

Thanks to Sam Ruby for the suggestion.

91eb8f5fbf Fix Recursive Includes
Another very amusing 3-year old bug from the main Instiki Bug Tracker
(don't they ever fix anything?): the chunk-handling code was supposed
to prevent recursive [[!include ...]] statements. Alas, instead of
actually preventing them it would -- when it encountered a recursive
include -- churn away until Rails ran out of stack space.
