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.
Using <object> and <embed> were forbidden for obvious
security reasons. Instiki now permits embedding video
via the HTML5 <video> element (Ogg/Theora encoded videos
only, with .ogg or .ogv extensions). You can even upload
videos with
[[foo.ogg:video]]
Instiki now support x-sendfile. See the Proxying page for
configuring Apache (with the x-sendfile module). Lighttpd
should work similarly.
Update Rails to latest Edge (hopefully converging on RC2!).
Dunno why this was buggered again. ":back" doesn't seem to function as it used to.
Also, when uploading a file from page "foo", it's important to return to "foo" after
a successful upload, rather than redirecting to the HomePage.
Finally, a favicon tweak.
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.
Instiki now runs on the Rails 2.3.0 Candidate Release.
Among other improvements, this means that it now
automagically selects between WEBrick and Mongrel.
Just run
./instiki --daemon
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.
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.
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.
Fix Session CookieOverflow bug when rescuing an InstikiValidation error.
Fix some random things which will cause problems with Ruby 1.9. (Plenty
more where those came from.)
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.
The action_cache plugin is now rather superfluous (Rails has native support for ETags, for instance).
And it wasn't working right with Rails 2.0.x (pages were being cached, and 304s were being returned
as appropriate, but cached pages were not being served).
Sessions are now stored in a cookie (signed and Base-64 encoded).
Form_spam_protection stores form_keys in the session.
Make sure spambots implement both cookies and javascript, by storing hashed (with salt) keys in the session.
