Browsing through the list I saw this post:

https://mail.zope.org/pipermail/zope/2011-June/176165.html

with reference to a directive in zope.conf:

products /usr/local/Products.CMFCore-2.2.4/

I tried it with the package Products.ZSQLMethods here:

http://pypi.python.org/pypi/Products.ZSQLMethods

but no product is added and I see no error messages.

The README.txt is not helpful and I found nothing useful in zope docs.
In despair, I tried python setup.py build/install and all I got is a lot
of zope packages being downloaded and dumped into the python install.

Could someone be so kind to tell me the procedure to install Products
from pypi?

Is it possible to do it also with old products not in pypi?

Also, what is the difference between zope.xxx and Products.xxx packages?

Regards,
Fernando

Hi Fernando,

the option 'enable-product-installation' in zope.conf has to be set to
on to enable product registration of old products in the Products
directory.

Stefan

Does anyone have any further information on this bug in 2.10 regarding
ZSQL methods? Would an upgrade from 2.9 to 2.10+ in an app using lots of
zsql methods cause unforseen issues?

I can not tell for sure if the problem was that one of the aliases
mentioned by Tres Seaver in results.py. However, I had a simple
application displaying merely one page and involving a few tables and
maybe 10 queries, and 2.10 could not even take hundreds of hits.

I made a simple Python program to hit the web site on the same page and
randomly changing the parameters. In my experience, if you cook up some
simple testing like this you'll quickly see the leak (I was using top in
Linux).

Stefan, thanks for your reply.

In the meanwhile I was indeed able to put products in INSTANCE/Products
(Zope 2.13.8). I did not know about that option you mention and I cannot
check it now, but the Products from pypi were being recognised, as long
as I put only the specific Product subfolder (not the whole pypi package
which contains "cruft" for eggs, whatever else, I still don't fully
understand).

However, with ZSQL Methods, the situation is different. It contains the
specific ZSQL Methods folder, but also Shared/DC/ZRDB. When loading,
Zope complains it can't find the module ZRDB/Search.py (or something
like that).

So, ZSQLMethods depends on Shared, but Share is not being recognised (or
at least not yet processed before ZSQL). How can I fix this? Somehow I
guess the pypi package should be made an egg and dropped in
lib/python2.6, and somehow configured. I couldn't yet find instructions
on doing this for Zope.

I've been trying to read about this whole new procedure[s] (setup tools,
buildout, eggs, virtualenv, ???), but I have the impression the
situation has been changing and it's quite hard to figure out what makes
sense or works right now.

I suggest using http://pypi.python.org/pypi/plone.recipe.zope2instance
(it is not Plone specific) and referring to the Plone documentation
for installing add-ons:
http://plone.org/documentation/kb/add-ons/installing

Thanks Lawrence,

I have already a zope 2.13.7 installation following the instructions and
using virtualenv. This seems to be an alternative to the buildout system
explained in those links.

There are several options in the add-ons page and I don't feel confident
it really applies to my case:

1) what is the ZSQLMethods package in pypi?
http://pypi.python.org/pypi/Products.ZSQLMethods/2.13.4. It's a zip with
some "egg-info" stuff in there but it is not clear that it really is an
egg (no .egg extension)

2) is Buildout compatible with virtualenv? The option to install an Egg
without Buildout is not recommended over there.

I would recommend using buildout, most people do, if you have problems
it helps to be in the main stream.

This is a source distribution that a binary egg will be automatically
built from. As you are using virtualenv you should be able to
easy_install Products.ZSQLMethods in the same way you installed Zope2.
(I hope you have some way of ensuring a consistent known good set of
packages equivalent to the buildout versions.cfg, without it you are
unlikely to get a working system.)

On my development machine I have a virtualenv python (using
--no-site-packages) which I use to run buildout's bootstrap.
