Hi everyone, I built my first Zope 3 instance with buildout yesterday. After I got an initial version working, I found it pretty lame to use "zope.app.zcmlfiles". With "zope.app.zcmlfiles" I had 100 eggs without it 84 eggs (this is somewhat project-specific.)
However, I had to add several unneeded dependencies, because the main "configure.zcml" of a package usually also includes the browser "configure.zcml". For example, I have a dependency on "zope.app.form", just because "zope.app.securitypolicy" (and other packages) create old-style forms. In fact, I do not even use anything declared in "IDefaultBrowserLayer", so any browser "configure.zcml" is totally overhead for in this case. In fact, anyone creating a new skin from scratch will want to avoid the same overhead. I think the solution can be very simple and be effectively backward-compatible for most cases: 1. Do not include the browser "configure.zcml" files in the main "configure.zcml" of that package. 2. (a) If the package has a SETUP.cfg and "package-configure.zcml", then add the browser "configure.zcml" include to that "package-configure.zcml". (b) If the package is currently loaded via "zope.app.zcmlfiles"'s "configure.zcml", then we will add the browser "configure.zcml" there. This solution would not be fully backward-compatible with people including package "configure.zcml" files manually. I think this is okay, since people often do not even want the browser stuff. A fully backward solution would be to put all the generic package configuration in a new ZCML file and combine them both in "configure.zcml". However, I find that solution very undesirable, so I hope noone will like it either. :-) I would like to get this change started as soon as possible to make it work for Zope 3.4. If noone objects, I will start with this in a few days.
