Egg on My Face

In yesterday's post, I wrote:

Chris McDonough made a start on the ZODB-related packages. Investigate and merge:

• BTrees
• persistent
• transaction
• ThreadedAsync
• ZEO
• ZODB
• ZConfig
• zdaemon

Build a meta-package which depends on all the ZODB and related stuff, and supplies the scripts to create storage server instances.

Howver, EasyInstall is smarter than that: if I ask it to install the ZODB sdist tarball, it downloads it, and then creates and installs its own egg. E.g.:

  $ mkdir -p zeoserver/bin zeoserver/lib/python
  $ PYTHONPATH=zeoserver/lib/python /path/to/easy_install \
    --install-dir zeoserver/lib/python --script-dir zeoserver/bin \

Phillip Eby rocks!

Chunking the separate packages out into their own eggs is a way lower priority than just being able to add install_requires=['ZODB3 = 3.6.0'] to my meta-packages. Breaking them out would help adoption of those pieces outside of Zope, so it is still worth doing. Meanwhile, we can just drop the appropriate ZODB tarballs inside the distribution directory for each release, and get on with packaging the rest.
