Re: [Zope] Question about Upgrading Zope and OS X Server
So OS X Server Snow Leopard comes with Python 2.6.1. Is there any reason to think that this Python version would cause problems with Zope 2.8.6? We have had nice stability with Python 2.3.5. Either way, is Zope 2.8.7 a significantly better choice than 2.8.6?

[Zope] Openflow_ZPygresqlDA_products_broken_on_ZMI
Hi, Can I install ZPygresqlDA without uninstalling ZPsycopgDA on the same m/c? Will it work properly? If it works properly I will install ZPygresqlDA-0.0.3 on dev Linux box & again import my source code & check whether it still appears broken? Please help me so that I can progress accordingly. If this doesn't work I will install all the products on dev with the same version as the products on live as suggested by you. Thanks a Lot in Advance!

Re: [Zope] Question about Upgrading Zope and OS X Server
Dan - we are using 64bit Zope 2.8.7 and python 2.4 with no problems for years now. It can do everything we want with regards to Python scripting, database connectivity etc. I can't think of any huge problems with staying on Zope 2.8.6/7 era. I have said before 2.10+ breaks lots of products that would take ages to hack about (especially for companies using Zope not individuals with time on their hands). I'm all for upgrading, bug fixing and refactoring normally, but the backwards compatibility with Zope makes it harder than it should be.

Re: [Zope] Question about Upgrading Zope and OS X Server
We're running several perfectly working 2.8 Zopes. They've been very stable. Annoying that Ubuntu insists on making Python 2.4 hard to install but for some of the servers we've changed back to Debian. On 7 December 2010 16:58, Dan Gaibel wrote: > Good advice here, thanks!
