[Zope] ExtFile/ExtImage compatibility with Zope 4/5?

[Jens Vagelpohl]

Hi Jesus,

I don’t know anything about ExtFile/ExtImage specifically, the only reference I was able to find is from old.zope.org and no one has touched it since 2007. It looks like there is no support.

The product will need to be repackaged as an egg or wheel first, otherwise you won’t be able to start any real compatibility testing. Zope 4 does not allow you to just unzip a product inside a products folder anymore.

Most products only need minor modifications once they are repackaged. How to do this repackaging is a general Python packaging question, I suggest you just look at Zope products that are compatible, e.g. https://github.com/zopefoundation/Products.PluginRegistry, to get an idea.

Zope products are hosted where all other Python packages are hosted: pypi.org.
