Problem with zope.org?
by Joachim Werner 11 Jan '01

11 Jan '01

Hi! I'm getting this or similar errors quite frequently these days: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /foo. Reason: Document contains no data Additionally, a 502 Bad Gateway error was encountered while trying to use an ErrorDocument to handle the request. Apache/1.3.12 Server at www.zope.org Port 80 This seems to be a problem with zope.org, not my local stuff. Cheers, Joachim.

hi, I have worldpilot almost working on a latest version of zope on NT. The only problem is that when reading a message I don't get the text of the message, everything else is file. The docs mention something about setting the default domain, how do I do that? thanks, tom --------------------------------------------------- WorldPilot - Get Synced - http://www.worldpilot.org The Open Source Personal Information Manager Server Powered by Python and Zope - http://www.zope.org

How can I compare the type of 2 variables in a python method? The instruction "if type(var1) == type(var2): ...." doesn't work.

Zope vs. java solutions : looking forward ?
by Henk Schets 11 Jan '01

11 Jan '01

Hi, We are planning a major update of our site (i.e. building a new one). At the moment our site is based on php,cgi, MySql and Apache on Linux. However, for the new site, we are considering other 'platforms' like Zope or Enhydra. I find Zope an elegant solution for our new site because we will be relying heavily on non-technical people contributing articles for publication. But the problem is this : the development will be made by a small commercial firm (the guys who work there are friends) and they are biased towards a java solution because they think this will be a standard for the future. They do not want to invest in learning Zope en end up in not being able to sell their acquired knowledge in this. I should note that, at the moment, they have no experience in Java nor Python, so they will have to learn one or the other. The problem I will be facing is the maintenance of the site and adding new features. What do you guys think ? Does Zope have a future with respect to e.g. Enhydra (this is Python versus Java for internet applications)? Does someone have experience with both and can you comment on the learning curve ? Thanks, Henk

RE: [Zope] Storing and Using Object references

Thanks for th pointer Shane, My original attempt with Andy's help was to use the REQUEST's resolve_url. However, the SiteAccess2 product breaks that method. I'll try your suggestions.

Store object2.getPhysicalPath(), which returns a tuple, in object1. To find object2 again, call object1.unrestrictedTraverse(stored_physical_path). Note that this only works in Zope 2.2.x+.

RE: [Zope] PoPy Installation. Where's the BEEF?

AAKK! I just noticed something... -----8<-- Start Snip --8<----- ZPoPyDA Import Traceback Traceback (innermost last): File "/usr/local/Zope/lib/python/OFS/Application.py", line 397, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/zope/lib/python/Products/ZPoPyDA/__init__.py", line 32, in ?

The PoPy module is not installed -----8<-- End Snip --8<----- Notice the paths in the traceback. I have one copy of Zope (no PostgreSQl support) in: /usr/local/Zope And another copy that will need to connect to PostgreSQL is in: /usr/local/EcoZope and ZPoPyDA is in: /usr/local/EcoZope/lib/python/Products/ZPoPyDA/ The traceback is displaying wrong paths. I searched the ZPoPyDA python source for hard coded paths but didn't find any. Is there an environment variable that sets this? Thanks for any help...

Deleting a Role Doesn't Appear to Remove Permissions
by Jason Grigsby 11 Jan '01

11 Jan '01

Today I ran into an issue in Zope where even after you delete a role that the permissions associated with that role exist. If a user has that role assigned to them, whatever permissions where last assigned to that role will be available. To test this, I created a test file with the following code: <dtml-if "AUTHENTICATED_USER.has_permission('Set Access Rule',content)"> foo </dtml-if> I chose Set Access Rule as a permission that is not normally associated with a regular user. Testing this page produced no foo because the user does not have access to the "Set Access Rule" permission on the content object (you could pick any Zope Object to test on). Then I created a test role. I assigned that test role to a user. I again tested the output and got nothing. I then gave the test role the permission to "Set Access Rule". Now when the page is reloaded, foo appears. Here is where it gets interesting. After deleting the test role, foo still appears. This means that the role, while supposedly deleted, still exists and is still assigning permissions. Finally, I create a new role with the same name as the test role I created earlier. This new role had the "Set Access Rule" button already selected--indicating in my mind that the role was never really deleted. If I am correct about this, this means that if we create a role and then delete it, we will need to make sure that the role does not exist for any users or they will continue to have the access that they had before. Has anyone else run into this or seen a reported bug similar? (I searched the Zope Bug Collector to no avail). -Jason

does xml-rpc work with zope and pcgi/apache?
by Roman Milner 11 Jan '01

11 Jan '01

I'm having problem getting xml-rpc calls to work with zope running on apache/pcgi. I'm using the python xml-rpc module to send an xml-rpc request that looks like this (when captured at the socket level): POST /asdf/1/ HTTP/1.0 User-Agent: xmlrpclib.py/0.9.5 Host: localhost:8888 Content-Type: text/xml Content-Length: 107 <?xml version='1.0'?> <methodCall> <methodName>listServices</methodName> <params> </params> </methodCall> What I get back from a zope running zserver only is: HTTP/1.0 200 OK Server: Zope/Zope 2.3.0a2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Thu, 11 Jan 2001 04:44:21 GMT Connection: close Content-Type: text/xml Content-Length: 229 <?xml version='1.0'?> <methodResponse> <params> <param> <value><array><data> <value><string>troubleTickets</string></value> <value><string>openTicket</string></value> </data></array></value> </param> </params> </methodResponse> When I send the exact same request through the same zope server running with apache/pcgi the response I get is a 404 (not found) error. I have an apache rewrite rule set up that works fine - I can go to /manage and so forth, and it works. The 404 makes a little sense, as the above posts to /asdf/1 which doesn't have an index_html in it, so in apache land this would be a bit like posting to a directory, but I thought that zope would have taken care of this some how. I have included the full error message sent back from the zope/apache below. We are working on a flash application that we were planning on having talk to zope via xml-rpc, but if xml-rpc won't work through apache, I guess we'll have to come up with some other way of talking to zope. Any help is greatly appreciated. ^Roman HTTP/1.1 404 Not Found Date: Thu, 11 Jan 2001 04:46:45 GMT Server: Apache/1.3.14 (Unix) mod_snake/0.4.1 Bobo-Exception-File: /home/Zope2/lib/python/ZPublisher/HTTPResponse.py Bobo-Exception-Line: 528 Bobo-Exception-Type: NotFound Bobo-Exception-Value: <HTML><HEAD><TITLE>asdf</TITLE></HEAD><BODY BGCOLOR="#FFFFF F"> <HTML> <HEAD><TITLE>Zope Error</TITLE></HEAD> <BODY> <TABLE BORDER="0" WID TH="100%"> <TR VALIGN="TOP"> <TD WIDTH="10%" ALIGN="CENTER">   </TD> <TD W IDTH="90%"> <H2>Zope Error</H2> X-Powered-By: Zope (www.zope.org) Python (www.python.org) Content-Length: 1591 Connection: close Content-Type: text/html <HTML><HEAD><TITLE>asdf</TITLE></HEAD><BODY BGCOLOR="#FFFFFF"> <HTML> <HEAD><TITLE>Zope Error</TITLE></HEAD> <BODY> <TABLE BORDER="0" WIDTH="100%"> <TR VALIGN="TOP"> <TD WIDTH="10%" ALIGN="CENTER">   blah blah blah...

Re: [Zope] ZWikiWebs Product
by Simon Michael 11 Jan '01

Off the top of my head - you don't mention whether they have Add ZWiki Webs permission - presumably they do are you using the zwikiwebs.zexp shipped with zwiki ? The separate zwikiwebs product is due to be retired and not recommended. -Simon
