[Zope] Same product in multiple instances automatically?
I'm running multiple instances of Zope 2.7.7 on a FreeBSD server. Each of those instances uses the same products, which I handle by making symlinks from the site's Products directory to that instance's Products directory: [1] /usr/local/www/Zope/Products/ZPsycopgDA [2] /usr/local/www/Zope/Products/exUserFolder /usr/local/www/Zope/instance1/Products/ZPsycopgDA - [1] /usr/local/www/Zope/instance1/Products/exUserFolder - [2] /usr/local/www/Zope/instance2/Products/ZPsycopgDA - [1] /usr/local/www/Zope/instance2/Products/exUserFolder - [2] ... To be honest, I'd expect something a little different, namely that each instance would automatically pull in all the products in the site installation (like [1] and [2] above), but that doesn't seem to be the case. Is that a configuration issue, by design, or by accident? It's not that I mind making a symlink here or there, but it's one more thing to remember when making a new instance and just feels wrong. -- Kirk Strauser The Day Companies ___ 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 )

That simply says that there is a default Products directory ($SOFTWARE_HOME/lib/python/Products), you can't get rid of it, and you shouldn't try to configure it here. The more interesting part is:: Name of a directory that contains additional Product packages. This directive may be used as many times as needed to add additional collections of products. Each directory identified will be added to the __path__ of the Products package. If you want your instances to use Products from some other directory, name it here. --jcc -- Building Websites with Plone http://plonebook.packtpub.com ___ 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 )

Problem solved, although I'm not sure why /usr/local/www/Zope/Products exists in the first place; maybe it was meant to be a symlink to ./lib/python/Products? Anyway, I think I can figure it out from here. Thanks! In the beginning, there was only one Products directory; this was in lib/python/ along with the rest of the software defining Zope. If you wanted to have, say, two or more running distinct instances of Zope you would have to copy the whole thing. Plus, with third-party products co-mingling with default products, upgrading became difficult. Thus was created the instance/software distinction. Everything needed to run Zope goes into the SOFTWARE_HOME; everything that defines a specific distinct instance goes into INSTANCE_HOME (3rd party Products, Data.fs, config files, logs, etc). You can thus manage (move, upgrade, etc) instances and software separately, and don't have to copy the whole thing to run many instances. (On my dev box, I may have 4-5 running at one time, and maybe 20 total!) This should explain why there are two such directories, and how they should be used. Short version: do not touch the SOFTWARE_HOME after it has been installed. In fact, it might be a good idea to remove all write permissions from that directory. You can co-mingle, of course, but be aware of what advantages you are losing. --jcc -- Building Websites with Plone http://plonebook.packtpub.com ___ 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 )

In other words, it seems to be a FreeBSD bug rather than a Zope bug, and I'm off to file a problem report so that it'll hopefully get fixed.
