Combine this with a regression test suite that exercised all of the site's functionality and pages, and you'd have something. As with Unit Tests, if it isn't tested, it should be deleted . --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Ok, quick and probably dumb idea how one could write a "ZLinkBot". If there is a central part in zope (ZPublisher?) which always runs when methods/scripts/etc are called, one could patch it to also log the path of the object which is called (the physical path!). Then just use a web spider which crawls the whole site, and after that compare the list which has been produced by the method above to the list of objects in your ZODB. Everything which hasn't been touched is an orphan. Could ZPublisher.Publish.call_object() be that central piece of code? cheers, oliver ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

You might manage a Quick and Dirty implementation, but to guarantee you've not missed anything you pretty much have to run the site as a program, which leads you to the classic computer science halting problem, I think. And that still doesn't address the question of external references. > By the way, new question: > Is this the correct mailing list for such suggestions? > If not, which one is it? For the original "has anyone implemented" question, probably 'zope'. For a discussion of how to implement this (or rather the effective impossiblity of implementing this reliably) this is probably the appropriate place. --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Just to make it clear what I'm talking about when I say "effectively impossible", consider the following bit of DTML: How are you going to figure out which objects that references? And this is a *very* simple example, just in DTML. You should see some of the indirection gyrations certain of my python code goes through . --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Well, I simply liked to know if anyone had already done it, so I simply
forgot to add them.

Well, the search seed could be an optional argument w/default value
'index_html'.

Interesting suggestions! Of course, these unfortunately won't handle
the acquisition thing correctly.
To dream a dream:
Consider a tab for folderish objects which allows to search them for
unused scripts/methods/... (after pressing a button because it would
possibly take a while), producing a sortable list of links, with
checkboxes for deletion...
Consider a tab for methods... which allows to parse them and produces
a sortable list of links to the other referenced methods...
Maybe I'll write something like that, but it would be my very first
Zope product.
By the way, new question:
Is this the correct mailing list for such suggestions?
If not, which one is it?
