Maruku uses greedy Regexps in a number of places, which,
in unfavourable circumstances, can lead to exponential
slowdowns (an apparent hang).
We worked around one such bug in Revision 355. Recently,
Toby Bartels found another (in Table Header parsing).
The "real" solution seems to be to make sure the Regexps
are not greedy. (Thanks to Sam Ruby for spotting the problem!)
Reverted the workaround in Revision 355, fixed Toby's
bug, and several other similar Regexps.
A Maruku-syntax <div> with an unclosed IAL (and, it seems, at least one equation)
would cause Instiki to hang. Badly. Requiring a 'kill -9' to terminate it.
Reverting the OpenDiv and CloseDiv Regexps to my, more simple-minded, versions
fixes the problem.
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.
Implement amsthm-like Theorem environments with Maruku.
Support is based on Maruku "div"s with special class-names.
Classes
num_*
produce numbered environments, and
un_*
produce un-numbered environments, where * is one of
theorem (for Theorem)
lemma (for Lemma)
prop (for Proposition)
cor (for Corollary)
def (for Definition)
example (for Example)
remark (for Remark)
note (for Note)
In addition, the class
proof
produces a Proof environment.
The LaTeX export works as expected, and these also work in the S5 view.
Bumped version number.
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.
Sam Ruby has been doing a bang-up job fixing the bugs in REXML.
Who knows when these improvements will trickle down to vendor distributions of Ruby.
In the meantime, let's bundle the latest version of REXML with Instiki.
We check the version number of the bundled REXML against that of the System REXML, and use whichever is later.
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).
Create a test case for utf-8 bug reported by Diego Restrepo. Seems to be related to WikiWord chunk handling.
Add some other tests, and fix a minor bug in vendor/plugins/maruku/lib/maruku/ext/math/latex_fix.rb.
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).
Added support for S5 Themes. Themes are stored in the public/s5/themes/ directory.
6 themes are included: default, nautilus, blue, flower, i18n, pixel.
