Recent wiki vandalism
« on: October 01, 2007, 03:53:19 AM »

Hello guys,

I think the recent issues are due to a vandalbot.
Seems there is no real permanent way to cure this, except maybe to add a kind of Turing test in the subscription form.

These two softwares may help to get rid of bots from subscribing:The contribution concept of reCAPTCHA seems to be particularly interesting.

What's your opinion Barry?
I might implement a prototype on a wiki sandbox (if I find time to do so).

I'm all for a more secure login-procedure, and would love to implement a CAPTCHA-test. However we need to find a solution/module that is compatible with ZWJ's current version (MediaWiki: 1.4.2) -- which is not at all a recent version. In case you did find one, please do let me know.

Me, I'm (once again) looking into upgrading the wiki to the latest version, which I suppose has native support for CAPTCHA. This is not something for the faint of heart though. Procedure:

- back up database (currently at 127.8MB, meaning I have to export table per table of which there are 26)
- back up current wiki's files
- set up test-domain, upload newest mediawiki version
- copy current ZWJ database to another hostname (so as not to touch the "live" db data)
- run upgrade.php
- if things haven't exploded by this point: overwrite older (current) wiki-files with the latest version on "live" server
- run upgrade php, pointing it to the "live" database
- bliss -- or permanent damage

I'll keep you posted...

But why?  What is the point of it?  They are obviously unaware of the low volume of contributions so they will be spotted and reverted straight away.

1.4.2!!!  Wikipedia (now at 1.11.0) uses a CAPTCHA for registration and before you can save an article with a web link within the text.

One day all upgrades will come with a Revert button  Wink

I just managed to successfully install 1.11.0 on a test domain and upgrade (a copy of) the old database in the process... huzzah! I'll be attempting the same on the live wiki. Stay tuned... Smiley

I'm now working on getting our custom template to play well with the new installation.
This includes backing up the live mediawiki install, with all its custom prefs and image folder, of course.

It's okay to continue editing on the live wiki for now, as its database will be the one that gets upgraded, once i've got the customization on the test server worked out.

Important note: Any image uploads made after I posted this message will not be included in the latest install. So I would urge all wiki contributors not to upload any images for the time being.

If that, erh, makes any sense to you Wink

Okay, I've got everything set up perfectly on the test-server -- with one caveat: Pagetitles that have an ampersand (&) in them don't load properly. For instance "Roxy & Elsewhere" stops at "Roxy", and then offers up a "yet to be edited" page. I've tried every possible way around it, to no avail. The problem's there because of the rewriting of "ugly urls" (index.php?title=Whatever to index.php/Whatever).

Since I'm on a shared hosting plan, my only option was to use mod_rewrite in a .htaccess file (see this mediawiki page and this one for more).
What's more, the wiki is now set up to be accessed from wiki.killuglyadio.com/wiki/Main_Page by default ("/wiki/" instead of "/index.php/"). This is how wikipedia does things. However it still does allow access via "/index.php/" - in order for Google to still serve up correct pages. With time, as Google crawls the wiki, it will start replacing the "/index.php/" pages with "/wiki/" pages and at some point I could drop the support for "/index.php/". If ya know what I mean...

My question: this ampersand problem, is it important? Important enough not to upgrade to 1.11.0? The obvious workaround would be to replace the ampersands in any page-titles with "And" instead of "&".

Is that acceptable for you guys? Let me know before I go on...

Aah, but I just figured out that all you have to do is insert a #REDIRECT[Roxy & Elsewhere] and it shows up fine! Smiley I guess that would qualify as a solution, no?

All done! I've also implemented the reCaptcha extension that Maroual suggested.
Poke around and let me know if all works well... Smiley

Thank you very much Barry.
This new sausage in the logo is cool.
Sure I started to hunt the errors, the only one I found so far is on my own page which uses borderline syntax.

I assumed the poodle logo was an early version - poodle looking out of page rather than into  as before.  I am off to explore and see if it was worth the effort  Wink

That was indeed an early version poodle! Fixed...

Ok, I guess the redirection should be considered as a temporary workaround because it prevents from using the 'What links here' functionality.

Plus I found a few exceptions that cannot be solved with a simple redirection.

London Symphony Orchestra Vol. I
will obviously not redirect to
London Symphony Orchestra Vol. I & II

Frank Zappa will not redirect to
Frank Zappa & the Mothers of Invention (The Album)
or
Frank Zappa & the Mothers of Invention (The Album - 2)

Anyway I will apply the workaround everywhere it is possible.
In a second time, I will move the pages and then replace "&" by "And" anywhere I can.
