[Zope-dev] Utility factory handling for zope.component
Tools like GenericSetup which deal with mangement of utility registration are a bit handicapped at the moment: even though you can register a utility using a factory the utility registration itself only runs the factory methods but does not keep any information on it. As a result you can not round-trip utility registration information or check if the current configuration has changed from an original configuration. To fix that I made a wichert-utility-factories branch of zope.component which adds the factory information to the utility registration. All changes are fully backbwards compatible at both the API and persistence level. If there are no objections I intend to merge the branch to trunk in a few days.

I think there are at least two other possibilities that I can see without having looked closer: 1. Use the info object. The point of the info is to contain this sort of information. 2. Make the component have a factory attribute. I have done this at some places for APIDOC as well. Option 1 seems the cleanest because it was designed d for this.

I think there are at least two other possibilities that I can see without having looked closer: 1. Use the info object. The point of the info is to contain this sort of information. Which info object are you referring to? The only information I could see for utility registration is a tuple, not an object. This is used to build the UtilityRegistration object when querying registration information, and I added a factory method there. 2. Make the component have a factory attribute. I have done this at some places for APIDOC as well. Why would a component need to know how it was created? I can envision that a component may very well have an attribute named factory for something else entirely.
