Hi all,

I updated the One-Click-Installer to the brand new Ruby 1.8.4. After  
that the Instiki 0.10.2 didn’t start any longer (Constant Logger::Format  
not defined). So I tried to update Instiki to 0.11.0

Now, while trying to migrate that Windows based Instiki installation  
from 0.10.2 to 0.11.0 I ran into this following error message:

> ```
> from d:/tmp/instiki-0.10.2/vendor/madeleine-0.7.1/lib/madeleine.rb:53:in `new'
> from d:/tmp/instiki-0.10.2/vendor/madeleine-0.7.1/lib/madeleine/automatic.rb:272:in `initialize'

> from d:/tmp/instiki-0.10.2/app/models/wiki_service.rb:147:in `instance'
> from script/import_storage:165
> 
> ```

(Let’s hope the formatting doesn’t get mangled…)

Might that be my fault? If yes, what might have caused it?

Happy rubying

Stephan

I think that was due to some version mismatch between  
instiki/rails/ruby-1.8.2. nm.

Some mystery bug in zlib (i think) which I could never isolate, but it  
caused the snapshot files to be considered as corrupt zips. Solution  
is a bit of black magic: extract the latest .snapshot file contents  
with a non-zlib zip (e.g. [7-zip.org](http://7-zip.org)), rezip them again as .gz and try  
the upgrade script again.
