(This is going into the Collector too.)

I've been working extensively with the ZCatalog in the past few weeks, using it to link to cataloged object using REQUEST.resolve_url(BASE0 + catalog.getpath(data_record_id_)). Along the way I've encountered a number of problems that have come up here on the list, mainly with people complaing about "Uncatalog of absent id". I'm running Zope 2.1.0 and 2.1.1.

1. Find Items to ZCatalog vs. IndexAware: Finf and IndexAware index object in the ZCatalog. The problem is that they do it using completely different formats. Find creates ZCatalog entries with a / in the beginning, and not url_quoted. IndexAware creates ZCatalog entries without a / in the beginning, and url_quoted.

For example, the following object /A Folder/an object will be cataloged two ways using Find: /A Folder/an object using IndexAware: A%20Folder/an%20object

2. REQUEST.resolve_url will only accept non url-quoted URLs, so if you want to use the result of a ZCatalog search on IndexAware objects you'll need to unurlquote them. ZCatalog.getobject uses REQUEST.resolve_url, so I assume it will also break on IndexAware objects. You have to pass a full URL for some reason, too - http://zope:8080/index_html, instead of /index_html.

The problem here is that Zope does not define what format an URL should be in. I propose that the standard format be unurl_quoted (spaces, not %20) with a '/' in the beginning, but the other way around is okay as long as there is a STANDARD. Is it too late to fix REQUEST.resolve_url, or is there some good reason that I need to prepend BASE0 every time I call it?
