Beware Perl Encode.pm v2.25 when updating TWiki 4.2.2 or WysiwygPlugin

Tag: new, perl, twiki, wiki — Sven Dowideit @ 11:19 pm

I just ran across a pretty annoying issue when updating one of my TWiki’s from 4.2.0 to 4.2.2. The server it is on was running Perl 5.10, but the Encode module was 2.25, resulting in Wysiwyg edits having all their spaces replaced with %20, and line feeds %0A ala

%20Debian%20equivalent%20of%20chkconfig%0A%0A/usr/sbin/update-rc.d%20avahi-daemon%20defaults%0A%0Ahttp%3A//wiki.linuxmce.org/index.php/Hardware%0A

(look familiar Martin? :))


perl -MCPAN -e shell
>upgrade Encode

Got me to Encode v2.26, which fixed it for me.

update: Martin’s just confirmed that it didn’t help him on perl 5.8.4, so perhaps its an odd combination of outdated modules?

Working towards Native TWiki attachment search

Tag: perl, search, twiki, twikiapplication, wiki — Sven Dowideit @ 7:31 pm

And along the way, TWiki’s inbuilt Topic and structured Search is going to get a boost too.

I’ve been working on trying to bring SearchEngineKinoSearchAddOn into TWiki properly - by adding it as a configuration item in the SearchAlgorithms. So far, its a pretty cool - it super fast, especially on my test topic set of 50,000 plants - even allowing simple structured queries based on TWiki FormFields.

The work will require a few refactorings that will be in TWiki 4.2.2 and above (planned for mid-September), so I expect things to move along quickly.

Enterprise Wiki - TWiki 4.2.1 update released

Tag: enterprise, new, perl, twiki, twikiapplication, wiki — Sven Dowideit @ 1:02 pm

This release makes over 150 improvements to the current Enterprise TWiki.

Along with many WYSIWYG Editing improvements, better UTF8 support, User mapping fixes and SEARCH improvements, This release contains an optimization that should see 4.2.1 being 10-30% faster than 4.2.0.

I will be updating the TWikiInstallers as soon as I can - the Windows installer should see the biggest impact, as I have managed to fix a number of SEARCH issues that are windows specific.

see TWikiRelease04×02x01 for more details.

Debian TWiki repository now with 212 TWiki Plugins, Contribs, Skins and more.

Tag: debian, enterprise, environment, new, twiki, twikiapplication, wiki — Sven Dowideit @ 3:09 pm

I’ve just updated the Experimental TWiki and Plugins repository. It now contains TWiki 4.2.0 and 212 Plugins, Contribs and Skins that you can simply apt-get install

To use them, add the following 2 lines to your /etc/apt/sources.list

deb http://distributedinformation.com/experimental/ experimental main contrib
deb-src http://distributedinformation.com/experimental/ experimental main contrib

then type

apt-get update

to update the available packages.

you can now see all 212 packages with apt-cache search twiki-

and install (assuming you don’t have twiki installed yet)

apt-get install apache2 twiki

and TWiki Contrib installation is as easy as

apt-get install twiki-bugscontrib

You will still need to use configure to enable Plugins.

Please report your experiences to me - bugs, gripes, you name it - its a work in progress. and I need your help!

TWiki 4.2.0 OpenIDUserContrib Consumer released.

Tag: enterprise, openid, perl, twiki, twikiapplication, wiki — Sven Dowideit @ 5:39 pm

I have just uploaded the OpenIDUserContrib for TWiki 4.2.0. It adds OpenID login and 1.1 Attribute functionalty to TWiki.

Currently, it disables Registration, and limits authentication to OpenID users.

It has the advantage over the OpenIDAuth apache module, that it automatically requests the User’s OpenId 1.1 attributes like Name, Email address directly from their OpenID identity.

While it trusts the user’s choice of ‘FullName’ registration attribute when displaying who made changes to topics, the TWiki topic source
actually stores the authenticating OpenID URI, thus their user details will be updated from the authentication server next time they log in.

Note that TWiki Topic based Groups are not yet implemented using this Mapper.

Future directions

  • add mixing of UserMappers to allow OpenID and ‘normal’ TWiki auth
  • turn TWiki into an OpenID identity server
  • add Safe Group definition system
  • add OpenId to TWiki’s registration process (would require openid auth first, then prefill registration details from any available attributes
    • This will require re-writing of TWiki’s inbuilt registration system
  • move the list of Known users and their mapping information from data/OpenIdUsers.txt to somewhere more scalable. (perhaps DBI)
    • combine the info TWiki uses persistently with the Session and other caching info OpenID11? uses

Net::OpenID11 (based on Net::JanRain::OpenID)

To make this work, I fixed the Perl bugs I found in Net::JanRain::OpenID, and renamed the resulting modules under Net::openID11 (as it is not OpenID2.0). I expect to upload these packages to CPAN some time soon.
