I am almost sure that the "import App.FindHomes" solution will never go into ZEO. It would tie ZEO to Zope (which probably is unwanted). It would be nice if ZEO would learn configuration options that would cover all of Zope's products locations. But unfortunately, ZEO is part of ZODB and Jim declared recently that he is the benevolent dictator for the ZODB project and he will usually defer things which can increase the complexity -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Someone else reported about a ZEO patch that does the same thing without a need to import "App.FindHomes". If you have Zope installed and ZEO is running in the Zope installation (shares its code), then "import App.FindHomes" in sufficient to import "App.FindHomes". Any plans to incorporate either of these solutions in the next release? I would like to avoid trying to explain how to do this to users of a third-party product that needs to be accessible to ZEO. And a related question. Any suggestions on how to support multiple product directories like a non-zeo config? I checked already and zeo.conf doesn't appear to support the "products" directive. "App.FindHomes" can be controlled via the envvar "PRODUCTS_PATH". If defined, it is a "pathsep" separated sequence of directories where Zope should look for products. It may contain "%()s" patterns with "" from "PRODUCTS_PATH", "SOFTWARE_PRODUCTS" and "INSTANCE_PRODUCTS". In these cases, the pattern is replaced by the corresponding path. Ahh... this sounds good. So, assuming App.FindHomes in imported, then all I would need to explain is how to add the necessary "export" lines to zeo.conf? (or maybe zeoctl?)
