Jacques Distler 513b2b16c1 Better
Put the "safe" XHTML sanitization in lib/santize.rb, rather than in lib/chunks/nowiki.rb.
D'oh!

Jacques Distler 758325923f Fix another ill-Formedness hole
The html5lib sanitizer does not necessarily produce well-formed output.
Take some "bad" input, wrap it in a <nowiki> tag and -- bingo! -- you get
ill-formed output.

Fixed. (Though, probably, one should fix the html5lib sanitizer, instead.)

Jacques Distler 2e81ca2d30 Rails 2.2.2
Updated to Rails 2.2.2.
Added a couple more Ruby 1.9 fixes, but that's pretty much at a standstill,
until one gets Maruku and HTML5lib working right under Ruby 1.9.

Jacques Distler 1b69b148de More Ruby 1.9 Compatibility fixes
Still a long way to go, but these will help.

Jacques Distler c427807274 Blahtex
Sync with latest Maruku.
Pave the way for Blahtex (PNG-based math) support (from Ari Stern).
   (no visible functionality, yet, but that will come)

Fix regexp for tag chunk.

Jacques Distler 45405fc97e New Sanitizer Goes Live
The new sanitizer seems to work well (cuts the time required
to produce the Instiki Atom feed in half). Our strategy is to
use HTML5lib for <nowiki> content, but to use the new sanitizer
for content that has been processed by Maruku (and hence is
well-formed).

The one broken unit test won't affect us (since it dealt with
very malformed HTML).

Jacques Distler 800880f382 Rough In New Sanitizer
Start work (which may not pan out) on a new sanitizer. Right now, it passes
all but 1 of the HTML5lib Sanitizer's unit tests. But it doesn't do much
of anything to ensure well-formedness. This is not an issue for Maruku-processed
content, but it is a concern for <nowiki> blocks.

(One solution would be to use the HTML5lib parser on <nowiki> blocks.)

In any case, this baby is 3 times as fast as the HTML5lib sanitizer.

Jacques Distler 41346bf8bd Efficiency: Entity handling
Previously, used a regexp to find and convert named entities in the content.
Now use a more efficient algorithm.
Similar tweak for converting NCRs before checking whether text is valid utf-8.
2008-05-17 01:43:11 -05:00
Jacques Distler 5ca0760f7c Efficiency: Sanitize Once
Envoke the HTML5lib Sanitizer just once (when the content is finally rendered),
rather than each time it passes through the chunk-handler.
2008-05-15 01:22:13 -05:00
Jacques Distler 6359d06ed1 Bug in Include Chunk-handler
Fix the chunk-handler for [[!include ...]] so that it behaves as expected.
2008-01-16 11:28:43 -06:00
Jacques Distler 4586614914 Misc Cleanup
Cleaned up some dependencies, and added a mime_types.yml file for Mongrel-compatibility.

Jacques Distler 6873fc8026 Upgrade to Rails 2.0.2
Upgraded to Rails 2.0.2, except that we maintain

   vendor/rails/actionpack/lib/action_controller/routing.rb

from Rail 1.2.6 (at least for now), so that Routes don't change. We still
get to enjoy Rails's many new features.

Also fixed a bug in Chunk-handling: disable WikiWord processing in tags (for real this time).

Jacques Distler 0f6889e09f Fix Unicode bug
Fix Diego Restrepo's bug (see Rev 184).
Update to latest HTML5lib.

Jacques Distler 1911d18f65 Performance
OK. This is a better way: define a custom TreeWalker which converts named entities to utf-8 as it goes. This avoids having to do an extra tree traversal in sanitize_rexml, AND avoids the trainwreck that is html5/inputstream.rb.

Jacques Distler 198d7847bd Performance
My REXML::Element.to_ncr (and REXML::Element.to_utf8) is horribly slow. For long documents, it proves more efficient to serialize to a string, apply String.to_ncr (or String.to_utf8) and then Sanitize the string.

Jacques Distler be8bb3d06d InterWeb Links
From Jason Blevins:  [[Web Name:Page Name]] or [[Web Name:Page Name|alternate label]] produce inter-Web links on the same Instiki installation.

Jacques Distler 08857ebe8e Fix Markdown (non-math) Engine, Tweak Themes
More tweaks to the supplied S5 themes.
Fixed a minor regression in the non-Math Markdown engine.

Jacques Distler 54aada824c Use Standard PageRenderer for S5 Content
From Jason Blevins: use the standard PageRenderer class to render S5 content. This way, WikiWords (etc) are processed in S5 slideshows.

Jacques Distler 119ab342dc Security: Sanitize <nowiki>
Another XSS hole: the contents of <nowiki>...</nowiki> was not being sanitized.

Jacques Distler 9035c98dc5 Bugfix: Category listings
Fixed bug where clicking on a category link would stomp on the "All Pages" listing.
2007-09-09 23:20:06 -05:00
Jacques Distler 5b182bd228 HTML5lib Bug
Fixed a bug in the HTML5lib tokenizer (affects S5 slideshows).
Some miscellaneous code cleanup. In particular, don't bother with zapping control characters;
instead, rely on is_utf8? method to raise an exception (which we do anyway).

Jacques Distler 5ff1b7f6da XSS Security Fix
There  was a XSS vulnerability in the handling of categories. Now they are escaped.

Jacques Distler 3de374d6c1 More fixes, sync with HTML5lib
Do a better job with the wrapper <div>s added by xhtmldiff and Maruku's to_html_tree method.
More tests fixed.

Jacques Distler 3ca33e52b5 Cleanup
Got rid of redcloth_for_tex.
Fixed almost all the busted tests.
2007-06-13 01:56:44 -05:00
Jacques Distler f0cf0ec625 Sanitize REML trees
OK. Enabled sanitization of rexml trees instead of strings.
My timing tests seem to be erratic. Can't tell whether this is really faster.
2007-06-05 17:13:44 -05:00
Jacques Distler bd8ba1f4b1 REXML Trees
Synced with latest HTML5lib.
Added preliminary support (currently disabled) for sanitizing REXML trees.

Jacques Distler 0db06a9fa3 To be really XML-safe, don't emit XHTML+MathML named entities. (Ported MathML::Entities to Ruby.) 2007-03-29 03:30:10 -05:00
