several questions about shared libraries and security
by Denis V. Gudtsov 03 Nov '05

Hello! The former I wrote python library. This lib is used to interact with database and defines some hi-level methods. I'm planing to use this lib in scripts, running on the same machine and zope. Now library is located on /usr/local/lib/. Is it possible to use it in zope? And the later i wanted to now how i can create a flexible access rules? There are two procedures needed: authentication and authorization. The first is not difficult to realize with "user folder". But what is the ability to control access rights of users for access to some types of information? I'm thinking it will about 10 users at all. Do I need to use pgUserFolder for this? Thank you,All! ;-)

It involves not only your individual setup, but also two distinct pieces of software, namely Zope and Apache. So until Zope gets mind reading code and full access to your apache config file (wherever that may live), no such luck. You might try the "RewriteRule witch" (a rewriterule generator) though, just to be sure that your RewriteRule contains no typos or mistakes: http://betabug.ch/zope/witch The day before yesterday there was someone with a very similar problem on #zope. His rule looked right but he got 403s always. After many tries it turns out some other part of the httpd.conf file was b0rken... duh. Regards, Sascha

About compressing files on the flight...
by Enrique Arizón 03 Nov '05

Maybe is just that I didn't take enough coffee this morning but I have been searching on Google and didn't find any "standard" way to compress uploaded files at flight while uploading to the server. Any hint?

URL Rewriting chaos
by zope＠tropolinux.com 02 Nov '05

Hi, I've tried everything in both the Zope and Plone books and read the Apache URL Rewrite guide also, but I just can't seem to get the silly thing working! I'm sure that it does ;-) but for some reason it is beyond me. Let me tell you what I've tried, and tell me which one should work: I am using apache to rewrite the urls. 1. Host monsters, both one in the zope root folder, and multiple in each plone site's folders. I have tried both with the mappings and without (even though the books say they're not needed with apache). 2. apache rewrite rules, this is how (the current attempt looks) please assume that the big url is all on one line, email programs may have changed that. <VirtualHost *:80> ServerName example.net RewriteEngine On RewriteRule ^/(.*) http://example.net:8080/plone_site/VirtualHostBase/http/example.net:80/Virtu alHostRoot/$1 [L,P] </VirtualHost> I have tried all combinations of things in the 'example.net' places above, including the fqdn, local ip number and local host name. Is there a shortcoming in the documentation here? Have I accidentally skipped over a word somewhere that was more important than I realised? Please help me on this, it is the MAJOR sticking point in convincing people that it's a good idea for us (and them) to move to zope :-) Thanks in advance.

You should consider: - upgrading to Zope 2.7.8 (IIRC, Silva does not yet runs on 2.8.x) - and install Python 2.3.5 - Zope 2.x is not supposed to be Python 2.4.x compatible -- bruno desthuilliers développeur bruno(a)modulix.org http://www.modulix.com

Cannot show blob image from sql server
by Thomas G. Apostolou 01 Nov '05

01 Nov '05

Hi all, i have made an external method to connect and get data from an sql server 2000, and then show them in a table. All works fine but one of the columns i retrieve is a BLOB image witch makes my external method to crash. So i used z SQL Method (witch is not prefared because there is a lot of customization and that's why i used External Method with Python from the begining) and it goes fine with retrieving and showing the data. But still i cannot show the BLOB image as image. It shows as a very very long string. Any sugestion-solutions-readings would be most apreciated. Thanks A LOT. PS : Newbie 8-( Thomas G.

Zope hangs with 'idle in transaction'
by Yuan HOng 01 Nov '05

01 Nov '05

Hi, list, I have a site running with Zope 2.7.6 under Linux. The site access a PostgreSQL database through ZSQL and psycopg 1.1.18. Only read access is used, nothing is written to the database. The one thing that annoys me very much is, with time passing, Zope will eventually hang and has to be restarted. When I use ps -Af to view the data connection status, I discovered that whenever Zope hangs, I can found all zope database connection in the status 'idle in transaction', like below: postgres 13605 799 0 16:22 ? 00:00:07 postgres: zopeapp backupdb 127.0.0.1 idle in transaction postgres 13611 799 0 16:22 ? 00:00:06 postgres: zopeapp backupdb 127.0.0.1 idle in transaction postgres 13614 799 0 16:22 ? 00:00:00 postgres: zopeapp backupdb 127.0.0.1 idle in transaction postgres 14078 799 0 16:26 ? 00:00:05 postgres: zopeapp backupdb 127.0.0.1 idle in transaction It seems zope is initiating some database transactions even though my site only access the database for reading. And those transaction somehow get into deadlock status and finally used up the maximun db connection allowed for zope. But why? How do I find out what zope is doing and why the connection are locked up? Any clue and direction pointing are heartily appreciated.

Permissions and Instances of ZClasses
by Dave Case 01 Nov '05

01 Nov '05

I'm trying to build a product through the ZMI (like the example in The Zope Book), I have some DTML methods in a ZClass were I want to be able to do a SecurityCheckPermission() on a permission that I have defined in the containing product. When I view the instance of the DTML, it doesn't see the permission. I'm able to at least see the 'View' permission... When I look around in the Permissions and Define Permissions of the various objects (both the ZClass, and the DTML methods), I don't see my permission in the lists, except for under 'Class Permissions' in the Permissions tab for the ZClass (were I have highlighted it, which I assume is correct?) The call to SecurityCheckPermission() looks like this... <dtml-if expr="_.SecurityCheckPermission('Manage Diary',this())"> I'm thinking maybe I'm calling SecurityCheckPermission in the wrong context? Making a product certainly can be confusing at times. :) Thanks! -- David Case Dav3xor(a)gmail.com www.builddiary.net
