Recently I had the opportunity to try the new buildouts of two Zope 3
projects, namely zope.tal and zope.fssync. In both, the dependency
specification in install_requires looks innocent:
These looks like dependencies that should only pull in a few more
packages at most. Unfortunately this is not the case. zope.tal somehow
ends up depending on, say, zope.dublincore and zope.lifecycleevent,
zope.app.publisher, zope.formlib, and a total of about 60 dependencies.
The story is very similar for zope.fssync. You'd not think the basic
page template interpreter should have a dependency on formlib.
Do we have a plan for unweaving these dependencies? It just doesn't seem
needed that such basic packages pull in so much of zope. Is there a
particular dependency that we could surgically alter to minimize this
explosion? It'd be useful to start publishing some dependency graphs to
identify critical packages. Is anyone already doing this work?
