Eggs Task Notes

Zope Ovulation

Phase 1: Manual installation of eggs

• load parts of Zope from manually placed eggs — works as expected, so long as you specify the PYTHONPATH both when installing the eggs and running z3.py

PYTHONPATH=eggs easy_install -d eggs/ ~/basket/zope_interface-3.0-py2.4-linux-i686.egg

Phase 2: Download of eggs from the network

• create a setup.cfg which contains the following

[install]

install_lib = ~/Projects/zhuevos/eggs

install_scripts = ~/Projects/zhuevos/eggs

• from within your Zope3 (huevos-rancheros-branch) checkout, do the following:

   $ md eggs

   $ PYTHONPATH=eggs python ez_setup.py

• if you already have setuptools installed on your machine, you may need to do:

   $ md eggs

   $ PYTHONPATH=eggs python ez_setup.py -U setuptools

• install the eggs:

   $ PYTHONPATH=eggs eggs/easy_install -f http://yergler.net/basket zope_i18nmessageid

   $ PYTHONPATH=eggs eggs/easy_install -f http://yergler.net/basket zope_interface

• you can the run z3.py, specifying PYTHONPATH=eggs

Phase 2 (alternate approach)

• from within your Zope3 (huevos-rancheros-branch) checkout, do the following:

   $ md eggs

   $ PYTHONPATH=eggs python ez_setup.py --install-dir ./eggs setuptools

• if you already have setuptools installed on your machine, you may need to do:

   $ md eggs

   $ PYTHONPATH=eggs python ez_setup.py -U setuptools

• install the eggs:

   $ PYTHONPATH=eggs eggs/easy_install -f http://yergler.net/basket --install-dir ./eggs zope_i18nmessageid

   $ PYTHONPATH=eggs eggs/easy_install -f http://yergler.net/basket --install-dir ./eggs zope_interface

• you can the run z3.py, specifying PYTHONPATH=eggs

Phase 3: Handling eggs in the Makefile

• perhaps an over-arching zope “meta-egg” which simply depends on everything else we want (even specific versions for a release?)

Phase 4: Loading ZCML from eggs

Projectification & Oogenesis

• create separate projects in svn for individual modules (zope.i18nmessageid, etc)
• replace the modules in the trunk with svn:externals
• curse because svn:externals are half baked
• create setup.py for the new projects with the ability to create eggs
• release (need to eggify deps as well)
• make eggs initially not zip safe

• convert places where we use file to use pkg resource APIs

• then finish pkg_resource work
• convert Make file to use easy_install
