-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Rationale - -------- The focus of the 2011 Pyramid GSoC project has been to port crucial Pyramid dependencies to Python3: https://github.com/Pylons/pyramid/wiki/Python-3-Porting At the end of this year's US PyCon, Lennart Regebro labelled[1] zope.component as "high-hanging fruit", due to the following factors:: - - "magic" - - Mostly tested via doctests - - "Hairy" dependencies (e.g., zope.proxy, zope.security) - - Many more optional / testing dependencies (ZODB3, zope.schema, zope.configuration, etc.) Based on IRC discussion at project kickoff[2], Joel Bohman, one of the two Pyramid GSoC students, has tackled this issue by factoring zope.component into two pieces: - - Joel has moved the core registry bits into a new 'zope.registry' package, now hosted in the Zope SVN repository: http://svn.zope.org/zope.registry/trunk Notes on the new package: - The tests in this package have been converted to standard unit tests: they all pass on Python 2.6, 2.7, and 3.2. - The "hairy" and optional / testing dependencies drop out: zope.registry depends only on zope.interface and zope.event. - - Joel made zope.component depend on zope.registry in a branch: http://svn.zope.org/zope.component/jbohman-zope.registry This branch leaves BBB imports intact. Proposal - -------- On bahalf of Joel and the Pyramid GSoC project, I would like to propose the following changes to the ZTK trunK: - - Land 'zope.registry' as a full ZTK package, with its own Launchpad artifacts, etc. This step may also involve moving bugs from zope.component to zope.registry. - - Merge the 'jbohman-zope.registry' branch of zope.component to the trunk, and bump its minor version accordingly. - - Cut releases of both packages. Once done, the remaining work to port zope.component should be smaller (much of the "magic" bits are now in zope.registry). We will update pyramid to use zope.registry in place of zope.component.
