And allow import to be made from an installed product similar to the way external scripts work. And let it find its extension automatically. So we could we could import the file myImport.zexp that resides in Products/MyProduct/import as MyProduct.myImport -- mit freundlichen Grüssen Robert Rottermann www.redCOR.ch ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Sounds good. One thing to watch out for - this needs to be tested with CMF, specifically with the FilesystemDirectoryView product. FSDV does not (as of zope 2.6) find its filesystem content if it is anywhere other than under lib/python/Products or $INSTANCE_HOME/Products. It is the only product I've tried that doesn't work anywhere else on $PRODUCTS_PATH. -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's UGLY-HAIRDRESSER!

I keep trying to forget about that. One approach may be to use the import mechanism but not the import search mechanism for that. So there's still a .zexp file in the software, but it's not part of the general import/export support. > The Extensions directory... errr.. this should probably not be in a > software home anymore.

So this one doesn't present a problem. The default list will only include the Extensions in the INSTANCE_HOME, and configuration will override that if something else is desired. > Personally, I think we should just hardcode '/home/fred/zope/import' > into the core as the import directory and be done with it. ;-) That's fine with me.

Actually, both of these directories have historically worked in much the same way as the Products package does. A software home may have (actually currently must have) an "import" directory. Zope currently slurps various TTW "examples" from a zexp file in the software home import directory. I'd really like to dump this dependency, but it would take a bit of work. The Extensions directory... errr.. this should probably not be in a software home anymore. I can't think of anything that would break were it to not be there anymore (besides products that depend on the physical layout of the software home, which shouldn't exist). > > I'm sure that utilizing these options in the config file will break > > things that rely on having a monolithic INSTANCE_HOME such as products > > that attempt to do something like "import_dir = > > os.path.join(INSTANCE_HOME, 'import'). > > Any product that does that will prove fragile eventually.

For products, we use the specified directories to add to the Products package, but that makes sense given that the base Products package is a required component. For imports and extensions, we should consider using the specified directories *instead* of the default. This is easy enough; if the directories are given as relative directories, they should be resolved relative to config.instancehome; the schema can then include the defaults and very little new code will be needed. > I'm sure that utilizing these options in the config file will break > things that rely on having a monolithic INSTANCE_HOME such as products > that attempt to do something like "import_dir = > os.path.join(INSTANCE_HOME, 'import').
