Zope, Python 2.4 pythonScripts import problem

[krzychu@bmpg.pl]

Hi,

I have installed brand new platform - Zope-2-7-6, Python 2.4.1, Plone
2.0.5, OS Debian 1:3.3.6-2.

After import a old Plone site from the following platform
Zope-2-7-4, Python 2.3.3, Plone 2.0.3 to the new one, I get error when
I visit PuthonScript in the ZMI.

"invalid syntax (Script (Python), line 1)"

There 2 are examples of 1 line:
from DateTime import DateTime
and
request = container.REQUE ST

There is no syntax error!

When I just save this script in ZMI then error disappers :)

What is the reason???
KK

p.s I have the same problem when I import to the same platform but with
Python 2.4.0

You may then ask in a zope or plone list. This is a python specific
list. But I will answer you any way.

So, you are exporting the plone site, then importing it? I had once some
problem like that and the solution was to call an script that compiled
all python scripts again. I'm not sure if this solves your problem, but
you may look at the first script here:

As I said, you may ask in a zope or plone list for a better answer. My
best guess is that somewhere there is some old compiled version of your
script.

I just have to warn you that some persons in the zope list are going to
tell you "Python 2.4 isn't a supported option for zope". So, you may use
it only for testing and not in a production environment.

Re: Zope, Python 2.4 pythonScripts import problem

I see that Python 2.4.x does not work with Zope-2-7-6 properly. When I
start zope I get warning that I should recompile my pythonScripts by
executing manage_addProdu ct/PythonScripts/recompile. I do it and get
list of scripts whoose were compiled but when I repeat that action I
get the same list of scripts. It doesn't compile them -> when I visit
script by ZMI I still get the following error message "invalid syntax
(Script (Python), line 1)".

The first script at page
http://www.zope.org/Members/goppelt/2-4-3Upgrade gives no effect ->
outcome is "invalid syntax (Script (Python), line 1)" error i scripts.

I'm affraid that I will have to resign with Python 2.4.x :(
I read that Python 2.4 was complaisant back but I don't think that
Zope-2-7-6 is???

Please read the docs that come with zope. No version of zope supports python
2.4 right now. For zope 2.7 and zope 2.8 the python version to use is python
2.3.5.

Everytime a new version of python is done a lot of stuff is checked to make
sure it works and minor changes are made. I know it is possible to get
zope2.7 and 2.8 working fine on python 2.4 but that should only be done by
zope developers and not by zope users.
