Re: [Zope] questions about migrating forwards

The ExternalFile product is quite old, and could likely use a maintainer to keep it up to date. I haven't seen Craeg Strong (the author) around in Zopeland for quite some time: he might be happy to hand it over to you as a person who still needs to have the product work.

Subject: [Zope] questions about migrating forwards
Hi list
We have a legacy web service that is running on Zope 2.6.2 with Python 2.3.3
For various reasons - security, maintenance etc we have decide to try migrating
this forward to a current version of python and zope.
e.g. Python 2.6 + Zope 2.12.2
I have a new clean SUSE linux 11 installation with the correct python,
setuptools and I am using virtualenv to create a sandbox
I have installed the zope 2.12.2 and configured it in much the same way as the
older system - (zeo with two data files, + 1 zope instance.)
All is good and I can start up the instance and access the management pages.
My next step is to get the Products list that we were using running. Here I
have run into two problems
1. ExternalFile
This fails to load with the error 'ImportError: No module named Interface'
(stack trace below)
I tested this with zope 2.11.4 and it works ok.
Either port ExternalFile over to using zope.interface or find a new product to
do what ExternalFile was doing for you.
2. ZMySQLDA
This fails with the message 'ImportError: No module named _mysql'
again this works ok on zope 2.11.4
So I guess there is a key step that I am missing out or a path, or installation
that is required.
The main difference is that 2.12 is installed using virtualenv and then
easy_install
You need to install mysql-python into virtualenv, activate your environment and
use easy-install to install mysql-python from there.
e.g. bin/easy_install -i http://download.zope.org/Zope2/index/2.12.2 Zope2
Are there known incompatabilities with these Products ? or is my installation
just not quite right.
Thanks Andrew

Likely your mysql-python installation in not working correctly. The problem happens on the Python import level and has nothing to do with Zope directly...perhaps file permission issue or a messed up PYTHONPATH or sys.path or something like that. By using virtualenv, you have to make sure that your third-party modules are installed within the virtualenv environment.

I have installed the zope 2.12.2 and configured it in much the same way as the

My next step is to get the Products list that we were using running. Here I
have run into two problems
1. ExternalFile

2. ZMySQLDA
This fails with the message 'ImportError: No module named _mysql'
again this works ok on zope 2.11.4
So I guess there is a key step that I am missing out or a path, or installation
that is required.
The main difference is that 2.12 is installed using virtualenv and then
easy_install
e.g. bin/easy_install -i http://download.zope.org/Zope2/index/2.12.2 Zope2
Are there known incompatabilities with these Products ? or is my installation
just not quite right.
Thanks Andrew
