Item8096: DBCachePlugin's copy of TWiki:DBCacheContrib calls Foswiki:DBCacheContrib storage modules

In a fresh install of Foswiki 1.0.4 and the latest DBCachePlugin, the following error will be the only output received when trying to visit any page:

Can't locate object method "store" via package "Foswiki::Contrib::DBCacheContrib::Archivist::BDB" at /www/foswiki/lib/TWiki/Contrib/DBCacheContrib.pm line 336

I found that DBCachePlugin's copy of DBCacheContrib ends up calling the Foswiki::DBCacheContrib whenever it tries to access the storage module. It's because lib/TWiki.pm (I'm assuming) defines *TWiki::cfg = \\%Foswiki::cfg; and DBCacheContrib calls the store function via $TWiki::cfg{DBCacheContrib}{Archivist}....

I worked around this by adding the following after the 'use' statements in lib/TWiki/Contrib/DBCacheContrib.pm:

$TWiki::cfg{DBCacheContrib}{Archivist}='TWiki::Contrib::DBCacheContrib::Archivist::Storable';

Based on the comments in http://foswiki.org/Tasks/Item1346 it appears that this started in 1.0.4. This was my first install of Foswiki so I'm not sure if it was present before.

I can confirm, that the suggested workaround works. In my eyes this bug is therefore more related to DBCacheContrib, which caused me to change this in the "Affected Component" formfield below.

To everybody who encountered this bug:
Please also have a look at Item1612, which seems as well be related to

lib/Foswiki/Contrib/DBCacheContrib/Archivist/Storable.pm

Is this related?

I can imagine that there are problems installing the current DBCachePlugin - which is still in tmwiki namespace and comes with an old internalized DBCacheContrib - with an up-to-date DBCacheContrib. The new DBCacheContrib comes with much advanced storage mechanisms. Alas, the port of DBCachePlugin has not been straight forward. It is one of the plugins that went to the end of my detwikification crusade as it is one of the harder jobs. Once done, this bug reported here will be solved as well. Setting this to waiting for me so that I don't forget to docu upgrades to this bug.

DBCachePlugin has been detwikified finally. So I assume this problem as solved.
