Jacques Distler e0df6c8a6a Updated Tests and Sanitizer Fixes for Revision 439 2009-09-25 15:59:43 -05:00
Jacques Distler 513b2b16c1 Better
Put the "safe" XHTML sanitization in lib/santize.rb, rather than in lib/chunks/nowiki.rb.
D'oh!
2008-12-01 10:29:46 -06:00
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 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 f8e74e53bd Rollback
The "optimization" of using arrays instead of regexps to
implement to_utf8 and is_utf8? (and their brethren) is 
actually no faster. Go back to the logically-clearer implementation.
2008-05-18 13:22:38 -05:00
Jacques Distler dfe22be5ff Minor tweak
This is slightly better.
2008-05-17 02:32:20 -05:00
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 ebc409e1a0 Ensure the_content REALLY is utf-8
Our check that the the_content was valid utf-8 was rather busted.
This one works right. In particular, we needed to expand NCRs before checking.

Jacques Distler c8196cbe41 More Unicode Fun
From Philip Taylor (via Henri Sivonen): disallow U+fffe and U+ffff.
2008-01-01 22:00:07 -06:00
Jacques Distler de125367b0 Update RDOC documentation.
Update the documentation for sanitize.rb, to match current behaviour.
2007-10-14 22:22:18 -05:00
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.
2007-10-14 21:07:46 -05:00
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 6fd6be8fea Sanitizer Fix
Whoops! Looks like Ryan changed the API for the HTML5 sanitizer. Bad, bad, bad.
Fixed now.
2007-08-30 16:06:20 -05:00
Jacques Distler 1bc5da0053 Use XHTMLSerializer, where appropriate. 2007-07-04 18:53:03 -05:00

Jacques Distler 2da672ec5b Many Minor Fixes
Fixed a whole bunch of minor stuff.
Had a go at getting some of the plethora of broken tests to pass.
2007-06-12 17:37:55 -05:00

Jacques Distler bd8ba1f4b1 REXML Trees
Synced with latest HTML5lib.
Added preliminary support (currently disabled) for sanitizing REXML trees.
2007-06-05 16:34:49 -05:00
Jacques Distler 4dd70af5ae HTML5lib is Back.
Synced with latest version of HTML5lib, which fixes problem with Astral plane characters.
I should really do some tests, but the HTML5lib Sanitizer seems to be 2-5 times slower than the old sanitizer.
2007-05-30 10:45:52 -05:00
Jacques Distler e1a6827f1f Rollback Switch to HTML5lib
Apparently, HTML5lib does not handle astral plane unicode characters correctly.
Which makes it useless.
Return to the previous sanitizer.
2007-05-29 23:57:39 -05:00
Jacques Distler 6b21ac484f HTML5lib Sanitizer
Replaced native Sanitizer with HTML5lib version.

Unit tests, galore.
