Update Bundler to 1.0.15.
Update Rails to 2.3.12.
Update rails_xss plugin.
The latter two were the
source of a considerable
amount of grief, as rails_xss
is now MUCH stricter about what
string methods can be used.
Also made it possible to use
rake 0.9.x with Instiki. But
you probably REALLY want to use
ruby bundle exec rake ...
instead of just saying
rake ....
Use Bundler to manage RedCloth
gem. 4.x should be much faster
and less buggy. Unfortunately,
it doesn't support mixed
Textile/Markdown syntax. So
we keep an (appropriately
renamed) copy of 3.x around,
for the users of the "Mixed"
text filter.
Completely removed the html5lib sanitizer.
Fixed the string-handling to work in both
Ruby 1.8.x and 1.9.2. There are still,
inexplicably, two functional tests that
fail. But the rest seems to work quite well.
Apply the same methodology, as in Revision 432,
to the category chunk-handler. This completes
the replacement of all the code that looks like
if string.is_utf8?
do something
else
complain
end
with code that looks like
string.purify
do something
Refactor the upgrade_instiki rake task.
Based on the (very nice) JHerdman's
64d305f2a8
but defaults to 'production' environment, instead.
Instiki users don't know about production/development/test.
Instiki defaults to 'production'. So should its associated rake tasks.
Added the ability to rename existing pages.
[[!redirects Some Page Name]] redirects Wikilinks [[Some Page Name]] to
the current page (assuming "Some Page Name" does not exist).
Real pages trump redirects (though this may change, depending on
user feedback).
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!).
When a Web uses one of the Markdown Text Filters, and you export
all the pages as a zip file, you'd like the MathML and SVG to
render when the pages are viewed locally. This means saving them
with a .xhtml extension. Users of non-XHTML-capable browsers or
Textile users should still get .html files.
Ruby's String.sub!(pattern, replacement) routine is fundamentally
broken. But the block version works fine.
Using the broken routine in the Chunk handler was a subtle mistake.
WikiWord (and the like) could wreak havoc in equations. Protect them
(the way <a>, <pre> and <code> blocks are protected).
For some reason, this doesn't seem to work in inline equations.
Maruku is doing something funny there ... => one failing Unit Test.
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.
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.
Another request from the old (and apparently defunct) Instiki Bug Tracker:
allow single letter WikiLinks, e.g. "[[a]]". Requested by a Japanese user.
Fixed.
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.
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.)
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.
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).
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.
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.
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).
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.
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.
