Ok, no worries, I'll keep using 2.3.4.

But the unit tests do pass. Can you do the following and retry: - Edit your zope.conf to show 'debug-mode on' - Run Zope in the foreground, and not as root, e.g. '$ bin/zopectl fg' from your instance home. See if you get any useful output.

Hi, Does someone know if final Zope 2.8 will run with python 2.4 ? I currently use Zope 2.7.2 and I tried rebuilding eveything on python 2.4 Zeo server starts, Zope server do not, and apparently before event.log logging starts... Thanks.

Zope 2.7.3 database pack fails
by Dennis Allison 01 Dec '04

01 Dec '04

Well, the ol' Data.fs got bigger (now 3.9GB) and so it's time to cut it back down to size. Unfortunately, just clicking "pack" on the control panel does not seem to do the job. This Data.fs has a history (2.5.1b3, 2.6, and now 2.7.3). The question is, how to pack it.

Sharing images between different sites
by John Poltorak 01 Dec '04

Is there any way to set up an images folder which can be shared between several sites under one zope instance? If so how would I reference them if they were all in the /images folder? -- John

Using ZGDChart with a python script as data method
by Josh 01 Dec '04

01 Dec '04

Hi, I am attempting to use data gathered by a python script to create a chart with zgdchart. I am using zope 2.6.4, zgdchart 0.6.4 on windows 2000. Within a zgdchart object, if I use a dtml method as the data method with code such as: <dtml-return "(('syd','melb','bris', 'adel', 'perth'),(5, 7, 6, 4, 6),(5, 10, 5, 1, 6))"> the chart works fine. When I try to use a python script as the data method, with code such as: return (('syd','melb','bris', 'adel', 'perth'),(5, 7, 6, 4, 6),(5, 10, 5, 1, 6)) the chart fails to be produced. Can anyone provide any tips? Thanks, Josh

I'm trying to follow the directions on how to change the Plone JPEG logo and had a question about a snag... When i log into ZMI I can only "Add" a very restricted set of types everywhere. e.g. I can't add content of type Images.....just Archetypes Content, Plone Conent, some CMF stuff. Any help greatly appreciated.

Which database?
by John Poltorak 01 Dec '04

I'd like to connect up a database to Zope, but have no real database experience. My choice is between MySQL and PostgreSQL. Is there any difference between them from Zope's POV? -- John

I disagree - not every project needs a DBMS that supports ACID transactions and foriegn key integrity checking (which, by the way, MySQL has supported for a couple of years at least if you use InnoDB tables instead of MyISAM). In 99% of small web applications, and even some large ones, the integrity checking can either be done on the client side, or even ignored all together (a really _bad_ idea). If you're dealing with 5 tables it really isn't hard, and if you're just using the database as a backend to an object-relational mapping system you can avoid many problems. Of course, there are times when they are needed. The important thing here is to choose the DBMS that is best suited to your needs. If you will be doing few inserts and many simple selects, and don't need your DBMS to manage foreign keys for you, then use MySQL. If you're going to deploy (or can foresee youself deploying) several applications that use the same system then you can save yourself many headaches by choosing one that does. > > You should hit the MySQL, PostgreSQL, etc. mailing lists, and ask a few > > questions with your needs in mind. > > > > Spend some time outlining your needs, and you'll reap the benefits down > > the road... > > > > Agreed, x2! You can make that x3, but if you choose the wrong one now you will pay the price. My basic rules of thumb are like this: Basic web app (INSERT/UPDATEs rare, many simple SELECTs): MySQL/MyISAM App that needs ACID/relational integrity (more complex app, frequent updates, maybe more complex selects): MySQL/InnoDB Complex app that has multiple clients (web/desktop etc. Here stored procedures and referential integrity are real benefits): PostgreSQL. But I have no experience with Firebird. Just as a reference point, one of the busiest sites I know the backend of - Livejournal.com - uses MySQL. They're transitioning to InnoDB at the moment. On their system the critical feature was cost, rather than supporting advanced features. Anyway, on their current deployment they couldn't use any real integrity checks... -- Phillip Hutchings http://www.sitharus.com/ sitharus(a)gmail.com / sitharus(a)sitharus.com
