i have an account with phpwebhosting. i was able to install zope but when i runzope it begins @ hostname domo.phpwebhosting.com instead of starting @ mydomain.org in zope.conf i specified in <http-server> address mydomain.org:8080 and still no luck, any pointers?

Catalog problem
by Kevin Carlson 09 Feb '05

09 Feb '05

Hi all, I have a Zope db that contains several thousand documents all indexed in a single catalog. When I query this catalog in the ZMI, I get results, but when I query this catalog as an anonymous user through a dtml-method, no results are returned. The catalog in question is actually the portal_catalog from a CMF-1.3 and I am curious as to whether or not the allowedRolesAndUsers index is automatically referenced when querying the portal_catalog? Also, when I try and reindex some of the indices, I get a POS key error... Anyone have any thoughts on this? Thanks.

I tried your suggestion, but it does not work in Zope. I createad a simple Script(Python) object like this: print 'ciao ciao'.encode('base64') return printed But when I try to see it from Zope it returns this error: Error Type: SystemError Error Value: module "encodings.base64" failed to register Bye

Well, I will check the options I used to compile python (I think it was default options). But I think that threading is mainly required for the Zope Servers (HTTP, FTP, WEBDAV), which is precisely the part of the functionality we move to Apache in the attempt I did (each child process runs a Zope instance that only has one thread, i.e. that only handles one request at a time and that only has 1 connection to ZEO). Another place where threads were needed is ZODB, but again, in my attempt, ZODB is handled in an external ZEO instance.

Yes, I still have a Zeo instance running, because mod_python does not provide a "global" interpreter, so there is no way to give access to a FileStorage (because each child process would try to open/read/write it, so there would be locking problems, etc, on the file). Yup, well, I use the Zope module standard functions to read configuration for a zope.conf file, where I have declared my Zeo server. The main difference between the standard zope.conf file and the one I use it that the Servers (HTTP,WEBDAV,FTP) section is removed. So I guess that a question I will soon hear about will be : how to get WEBDAV/FTP working ? I have no answer, if I needed them, I would keep a separate "real" Zope instance for that purpose I guess, that would connect to Zeo. But it may be possible to do some mod_python handler for WebDav and FTP, as Apache support these protocols, as far as I know. Before submitting a feature+patch on zope.org, I would like to make more tests : + load tests + replace one of our "real" Zope instances by this in our production environment + get more feedback (I have contacted mod_python developper, so he may have a look too) ... But of course, at some point, I do it. About load testing, the first very simple AB test we did : "out-of-the box zope.conf" Zope instance vs. "out-of-the box httpd.conf" Apache2/mod_python/ZopeHandler showed that the later was 2 times faster. But I think I have to make the number of child processes in Apache and the number of connections (both implying the max number of sumultaneous requests that can be handled on both architectures) and then load test again. At least I can say that with Apache2/mod_python/ZopeHandler CPU repartition is much better for multi-cpu servers because each request really runs in a separate OS process.

Hehe, well, the community is very greatful :-) Hopefully this can end up as something that ships with Zope by default? Can you submit the work you've done to http://www.zope.org/Collectors/Zope as a feature+patch? > My installation has now been running for 5 days, and I have still no issues, > both browsing my site or using the ZMI. Coool, have you tried load testing it with AB or some such?

Yes, during the first tests we did at lastminute.com, we saw a better load repartition accross processors on our test servers. This is because each request is handled in a dedicated Apache process, which is linked to an independent python process.

As I understand it, a normal zope install would only run on a single proc, but this sounds like it would result in that no longer being the case. Thanks!

CMFBoard w/PortalTransport question
by Shankar Acharya 09 Feb '05

Hello, I need some help getting PortalTransport and/or CMFBoard configured correctly such that email messages sent to the forum email address show up in the forum. So far I have been successful in sending email to the *public* forum which is setup with (state = open). However, when I send email to the *members* forum (state = members), I see the following in my Zope 'event.log' 2005-02-08T04:51:41 INFO(0) PortalTransport Products/PortalTransport/MailTransportInfo.py[143]:deliver Can't find destination location. Here are the config details for the CMFBoard forums. ======== FORUM #1 ======== id: public state: open email address (reply-to): public-test-forum(a)stix.pri email address (return-path): public-test-admin(a)stix.pri ======== FORUM #2 ======== id: members state: members email address (reply-to): members-test-forum(a)stix.pri email address (return-path): members-test-admin(a)stix.pri The email address used for sending messages to both forums is 'my-user(a)stix.pri', which belongs to Plone site member 'My User'. This user has 'Forum writer' role in both forums. I would greatly appreciate any pointers the group has to offer.
