Jacques Distler 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

Jacques Distler b80995dbdc Equation Numbering in Maruku+itex2MML
This was spooged by Revision #263 (to accommodate) BlahTeX/PNG support.
Hopefully this way will work in both modes.

Jacques Distler 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.

Jacques Distler 13b7e1d766 A Real Fix For the "Backslashes in Included Equations" Bug
Ruby's String.sub!(pattern, replacement) routine is fundamentally
broken. But the block version works fine.

Using the broken routine in the Chunk handler was a subtle mistake.

Jacques Distler 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.

Jacques Distler a6d80426a9 Revert Revision 338
That didn't work with nested includes:
A: [[!include B]]
B: [[!include C]]
C:   fubar!

Added a test for that issue.

Jacques Distler 41006d20ef Fix the "Backslashes in Included Equations" Bug
See
  http://golem.ph.utexas.edu/instiki/revision/Known+Bugs?rev=3#IncludedEqs

Who knew that

      @pre_rendered = String.new(self)

was not the same as

      @pre_rendered = String.new
      @pre_rendered = self

?

Jacques Distler 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.
Maruku is doing something funny there ... => one failing Unit Test.

Jacques Distler 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.

Jacques Distler 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.

Jacques Distler 8832dd3438 Version 0.16.1
Make this version (minimally) usable with Textile Markup:

   For Webs with "Textile", "RDoc" or "Mixed" markup option selected,
   send text/html instead of application/xhtml+xml. This makes this
   software minimally usable with those markup dialects.

"Markdown+itex2MML", "Markdown+BlahTeX/PNG" and "Markdown" should work
as before, sending application/xhtml+xml to capable browsers.

Bump the version number.

Deleting a page removes all revisions of that page.
Deleting a Web removes all pages (and all revisions thereof)

Jacques Distler c3c33b68dd Multiple leading capital letters in a WikiWord
CMyApp  is a WikiWord (at least, on other Wiki systems, like TWiki).
Should allow that here

Also, choose a more obscure name for the thread-local variable tracking
included chunks.

Jacques Distler 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.

Jacques Distler 1b54b695c3 Single Letter WikiLinks
Another request from the old (and apparently defunct) Instiki Bug Tracker:
allow single letter WikiLinks, e.g. "[[a]]". Requested by a Japanese user.

Fixed.

Jacques Distler 1192f70f44 @import In Published View
In the Stylesheet Tweaks, the owner of a Web can specify an @import rule
to pull in CSS styles form an external file. This worked in the "show"
view, but was broken in the "published" view.

Fixed.

Also, update a functional test to match Revision 313.

Jacques Distler 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.

Fixed.

Jacques Distler dcd3e63ae8 Nowiki Include
Previously,
   <nowiki>[[!include foo]]</nowiki>
would produce some garbage, like

instead of the desired rendered text,
   [[!include foo]]

Fixed.

Jacques Distler ad049bcc4b Drop hostname from cache key
By default, Rails will cache

    example.com/mywiki/show/SomePage
and
    www.example.com/mywiki/show/SomePage

In Instiki, this just leads to stale cached pages and frustration.
Fix that behaviour.

Be a little gentler in recovering from Instiki::ValidationErrors, when saving a page.
Previously, we threw away all the user's changes upon the redirect. Now we attempt
to salvage what he wrote.

Jacques Distler 5d2b0da4d5 Faster
Update dnsbl_check plugin to latest version.
Update Maruku to latest version.
In the wiki_controller, only apply the dnsbl_check before_filter 
  to the :edit, :new, and :save actions, instead of all actions.
  This makes mundane "show" requests faster, but does not 
  compromise spam-fighting ability.
