Hi,

I've a long list of categories (external to drupal taxonomy) and for each category I'd like to provide a block that offer some category aggregate info.

I'd like to keep the block list/configure interface (admin/build/block), so that users could decide if, where and when those aggregate info should be displayed. But I can't present the whole list of categories in the block interface.

As an example I picked up views to see how to dynamically create blocks.

But it doesn't seem that views do any garbage collection in the {blocks} table after a view is deleted.

A better example was core menu module that actually does some clean up.

Even themes leaves a lot of garbage in {blocks}.

How this is supposed to work?

Do you have a general approach to suggest to this problem? Does a module already exist to do some clean up? eg. a couple of switches that will ask: - would you like to clean all blocks assigned to a not installed module? - would you like to clean all blocks that are assigned to a not installed theme?

Shouldn't a policy exist in the docs to ask modules/themes to do their own clean-up?

I saw this problem seems to be solved in D7.
