wow, that went green! this might mean, we can directly include ZODB >= 4.0 instead, including the dependencies listed in https://github.com/zopefoundation/ZODB3/blob/master/setup.py

@plone/release-team should that get PLIP'ed? I'm unaware of anything else besides tests that should be checked though...

Jenkins (again although green on the first run): http://jenkins.plone.org/job/pull-request-5.0/535

Upgrading should be checked too

A PLIP would be good to be able to keep track of this. I guess this upgrade would require a Plone 5.1 release. The PLIP does not need to be long. Just mark this issue as a PLIP and add a few lines regarding the change and the possible risks.

@gforcada PLIP decisions should be directed to @plone/framework-team

Since ZODB3 3.11.0 depends on BTrees >= 4.0.0dev, you should also depend on Products.ZCatalog >= 3.1. This one includes a change, which raises a TypeError when a None value is indexed:

Raise a TypeError when trying to index or lookup None in an UnIndex. This is a required change for BTrees 4.0+ compatibility, which prevents objects without a clear ordering definition from being inserted in a tree.

This will result in a little more work, since depending on this ZCatalog version will result in some test failures. We need to make sure, we don't index None values in our indexers but a marker value instead, if we need to.

There a related discussion on the [Zope-dev] mailinglist: http://comments.gmane.org/gmane.comp.web.zope.devel/30447
And a related Github issue: zopefoundation/Products.ZCatalog#5

@thet thanks for the pointers, and yes, sorry I meant to mention the framework team not the release team :)

I this in Scope of Zope4 already?

[gforcada]

@jensens makes sense to bundle it with Zope 4 effort and/or being done afterwards...
