[Grok-dev] dependencies missing needed for Grok 1.1 backwards compatibility

[Martijn Faassen]

Hi there,

I'm trying to upgrade a project to use Grok 1.1. Some dependencies are 
missing from Grok proper that are needed for backwards compatibility.

In the past we discussed a "backwards compatibility" package that would 
have these dependencies on packages that used to be in Grok 1.0 but that 
Grok 1.1 doesn't pull in anymore. Someone who is updating a Grok app to 
Grok 1.1 could then also depend on this grokbackward package to pull in 
the old dependencies. They could then work on removing these 
dependencies step by step.

Do people think this is a good idea? The alternative would be to write 
upgrade notes asking people to change their imports, but the drawback 
would be that there's no way to get code working without changing imports.

The one I just ran into is zope.app.catalog, but I imagine there are 
more. Could someone do a comparison between the packages pulled in by 
Grok 1.0 and Grok 1.1rc1 and make a list?

Regards,

Martijn
