Scott Robertson had sent us some patches related to this that unfortunately are going to take some bandwidth to think about. Supporting previous database, where the pickles have the paths to the modules recorded in them, is apparently tricky business. Until then, feel free to experiment with Scott's patches and see what you folks think. --Paul

error when starting with ZServer
by Service Informatique CHSR 23 Mar '99

23 Mar '99

Hello, This is a weird error I get. Hope that it can be useful to track down a bug. I've got a base (Data.bbb.*) that is served by a PCGI/Apache Zope. When I publish this base with ZopeHTTPServer, no problemo, it just work fine. However, If I try to publish the base with ZServer, I get this traceback: -------------------------------8<------------------------------- Traceback (innermost last): File "./PubCore/ZServerPublisher.py", line 94, in __init__ publish_module( File "/home/webdevel/devel/Zope/lib/python/ZPublisher/Publish.py", line 877, in publish_module response = publisher.publish(module_name,after_list, File "/home/webdevel/devel/Zope/lib/python/ZPublisher/Publish.py", line 325, in publish (bobo_before, bobo_after, request_params, File "/home/webdevel/devel/Zope/lib/python/ZPublisher/Publish.py", line 616, in get_module_info module=__import__(module_name, globals(), globals(), ('__doc__',)) File "/home/webdevel/devel/Zope/lib/python/Main.py", line 103, in ?

I copied them with cp -R to do my tests: $ cp -R ZopeWithPCGI ZopeWithZHS $ cp -R ZopeWithPCGI ZopeWithZS $ cd ZopeWithZHS; ./start.py # it works. Then I shutdown the Zope process $ cd ZopeWithZS/var; ../ZServer/start.py # don't work. I wanted to "suck" all my sources from my site by FTP with ZServer to work on it offline, but I can't because of this stuff :-))) Hope that can help. And if anyone here has a solution, it is also welcome... Regards, Jephte CLAIN, Service Informatique CHSR

ANNOUNCE: The Instance Product Patch
by Scott Robertson 22 Mar '99

22 Mar '99

I just uploaded this patch to the contrib section of the zope web site. >From the README.... INSTANCE PRODUCTS PATCH This patch is useful for people who would like to run multiple instances of Zope from the same source directory, but have each instance have it's own database and product directories. Actually this patch allows each instance to share the Products in SOFTWARE_HOME/Products and to let the instance have it's own personal products under INSTANCE_HOME/Products. SOFTWARE_HOME is an environment variable that points to the directory that Zope is installed in, normally Zope-version/lib/python. INSTANCE_HOME is an environment variable that points to the directory that contains the var directory which in itself contains the Zope Object Database, normally Zope-version/. When Zope first starts, it loads all the products installed under SOFTWARE_HOME/Products/ into zope. Additionally if you set INSTANCE_HOME to point to a directory other than Zope-version/, Zope looks for a directory named var/ under INSTANCE_HOME and either creates the Object Database in that directory or opens the pre-existing one. With this patch Zope will also look under INSTANCE_HOME/Products/ for additional products to install, if the environment variable ALLOW_INSTANCE_PRODUCTS equals 'Yes'. The best way to accomplish all this is to use apache with pcgi and have something like the following lines in your configuration file. --Example httpd.conf file------------------------------ #...Other configuration directives. # Zope configuration maps / to the Zope.cgi CGI script and passes # authentication information. RewriteEngine on RewriteOptions inherit RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] # Launch an instance of zope for this Virtual Host <VirtualHost www.bogus.com> ServerAdmin webmaster(a)bogus.com # Inherit the above rewrite rule RewriteEngine on RewriteOptions inherit DocumentRoot /home/bogus ServerName www.bogus.com SetEnv INSTANCE_HOME /home/bogus/ SetEnv PCGI_SOCKET_FILE /home/bogus/var/pcgi.soc SetEnv PCGI_PID_FILE /home/bogus/var/pcgi.pid SetEnv PCGI_ERROR_LOG /home/bogus/var/pcgi.log SetEnv ALLOW_INSTANCE_PRODUCTS Yes User bogus Group bogus </VirtualHost --------------------------------------------------- - Scott Robertson Phone: 714.972.2299 - - CodeIt Computing Fax: 714.972.2399 - - http://codeit.com - ---------------------------------------------------

AW: [Zope-dev] Security tab in home grown Product
by Stefan Franke 20 Mar '99

20 Mar '99

It seems (just a guess) your Product inherits permissions for attributes it doesn't have. Do you define or inherit manage_main in your Product class? You could try to force a breakpoint at the beginning of manage_changePermissions via import pdb; pdb.set_trace() and inspect the variables there. manage_changePermissions itself is called directly from the security management form. Maybe this can light things up a bit. Stefan > -----Ursprüngliche Nachricht----- > Von: James A. Hillyerd [SMTP:james@blarg.net] > Gesendet am: Freitag, 19.

Could you, Martijn, or someone else, please say a little more about the above ? I really, *really* would like to see the code which tests whether the AUTHENTICATED_USER has (eg) read permission for a given object. I've studied the zope code and the docs. It fried my brain. But for this hangup, my client's extranet would be running on zope right now.

ZPOS? ZBase? ZPersist? I'd also like to settle on the final name for the database. Choices are: a. ZDB b. ZBase c. ??? Comments? --Paul

You could call it Z POS, but people might think it's a point of sale system. ZDB or ZODB is probably good, unless someone comes up with a great marketing-friendly term (Z Whizzo!).

Who did Pil integration? How's that Calendar coming along?
by Brad Clements 19 Mar '99

19 Mar '99

Yes, I'm begging for code. I now need to create a new image class called "photo" with some new properties, and I'd like to be able to generate thumbnails on-the-fly and cache them (with an automatic expiry from Bobo/ZDB). Someone on this list said they'd gotten Pil integrated with Zope, can you point me towards some hints? Also, two months ago someone showed a possible Calendar layout. I'm looking for something to do an event calendar for aviation events. What I'd like to do is add vCalendar support so a person could automatically download a whole bunch of events to their desktop if they desire. If I had a some kind of calendar code to start with, I could get vCalendar added much quicker.. Give me a boost, and I'll give it back to Z community.. ;-) Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com ICQ: 14856937
