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 61c3fb1ab9 Bump Version Number
Version 0.16

Also, allow Includes of single-letter pages.

Jacques Distler 0f843bc537 Slicker
Clean up the recursive-include code a bit.

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 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
   chunk18226682includechunk
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.

Jacques Distler a503e2b8ac Gentler
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 5d7d89d193 Fix Slowdown in Sanitizer Regexp
Deal with the issue:

   http://code.google.com/p/html5lib/issues/detail?id=83

by fixing a regexp used for sanitizing inline style attributes.

Jacques Distler 5d47fdff8b Make Interweb Links Work Right
Links to a published web should be to the 'publish' action, not to the
'show' action. Previously, the published status of the source, not the target
was used.

Also, correct display of the Navigation Links for the 'published' action.
2008-12-01 22:58:09 -06:00
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 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.)
2008-11-30 21:44:52 -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.
2008-11-24 15:53:39 -06:00
Jacques Distler 1b69b148de More Ruby 1.9 Compatibility fixes
Still a long way to go, but these will help.
2008-11-12 09:47:24 -06:00
Jacques Distler 7600aef48b Upgrade to Rails 2.2.0
As a side benefit, fix an (non-user-visible) bug in display_s5().
Also fixed a bug where removing orphaned pages did not expire cached summary pages.
2008-10-27 01:47:01 -05:00
Jacques Distler e1c7d035c9 Some more SVG attributes for the sanitizer
From Sam Ruby.
2008-07-28 10:57:55 -05:00
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)

Jacques Distler ca1e8de89c Minor Cleanups
Remove a no-longer-needed function.
&apos; -> &39;
Fix regexp for tag chunk.
2008-05-22 02:46:45 -05:00
Jacques Distler f6508de6dd Whoops!
In some circumstances, the new Sanitizer was double-escaping text nodes.
Fixed (with unit test).
2008-05-21 14:14:43 -05:00
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).
2008-05-21 02:06:31 -05:00
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.
2008-05-20 17:02:10 -05:00
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 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.
2008-01-14 14:46:38 -06:00
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.
2008-01-03 15:27:03 -06:00
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 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).
2007-12-21 01:48:59 -06:00
Jacques Distler 0f6889e09f Fix Unicode bug
Fix Diego Restrepo's bug (see Rev 184).
Update to latest HTML5lib.
2007-12-17 03:17:43 -06:00
Jacques Distler 207fb1f7f2 New Version
Sync with Latest Instiki Trunk.
Migrate to Rails 1.2.5.
Bump version number.
2007-10-15 12:16:54 -05:00
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 5dd75d4cb0 File Upload Links
I like this a little better.
2007-10-09 23:56:55 -05:00
Jacques Distler fbdf4c5dfe Fix Broken Test
Was not picking up user-supplied alt text in [[filename|Alt text:pic]].
Fixed.
2007-10-09 11:02:44 -05:00
Jacques Distler 0eb723e125 Accessibility: Use Uploaded File Descriptions
The file upload dialog asks for a description of the image or file to be uploaded. Use this as the default alt-text for the image and as a title attribute for a file link.
2007-10-09 02:51:38 -05:00
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.
2007-10-06 16:04:11 -05:00
Jacques Distler 3a3cfeaa9b Drop URI Chunk-handling
The URIChunk and LocalURICunk handlers were

1) Slow
2) Buggy (prone to produce ill-formed pages in edge cases)
3) Of dubious utility

So I ditched them. No auto-linked URLs, but who cares?
2007-10-05 16:25:41 -05:00
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.
2007-09-14 18:09:24 -05:00
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).
2007-09-06 10:40:48 -05:00
Jacques Distler 5ff1b7f6da XSS Security Fix
There  was a XSS vulnerability in the handling of categories. Now they are escaped.

Jacques Distler 6fd6be8fea Sanitizer Fix
Whoops! Looks like Ryan changed the API for the HTML5 sanitizer. Bad, bad, bad.
Fixed now.
