Problem with Apache+Zope
by G. Clifford Williams 26 Feb '03

26 Feb '03

I'm having a problem getting to the "manage" page of the zope server. My configuration is as follows. <VirtualHost *> ServerName zope.xyz.com ServerAdmin webmaster(a)clave.info RewriteEngine On RewriteRule ^/(.*) http://localhost:8080/$1 [L,P] #ProxyPass / http://localhost:8080/ #ProxyPassReverse / http://localhost:8080/ ProxyVia on </VirtualHost> Everytime a request for zope.xyz.com comes in it get's the main page but any attempt to go to zope.xyz.com/manage/ results in errors from the client machine about not being able to connect to "localhost:8080" It's set up this way because this machine is only accessible through port 80 So the idea is just to have Apache act as a gateway to the zope site(s) running locally on 8080. Any help would be greatly appreciated.

3 of 4 Zope threads hanging - how to find culprit?
by Dario Lopez-Kästen 26 Feb '03

26 Feb '03

Hello, I am experiencing 3 of 4 of Zopes threads hanging and only being released by restarting Zope. The threads have been hanging up to more than 78 000 seconds before we restarted the application. We use DCOracle2 all the time, several SQL-queries for each request. Due to the natuerw of the underlying SQL the response from the database can tale up to 15 seconds to complete, and requests get stacked waiting for the repsonse from the database server. This leads to the situation that only 1 Zope-thread responds to requests. There is no difference in the queries executed by each thread. Any advice in how to prevent threads from locking up is appreciated, as well as advice on how to find out why the threads lockup. Zope 2-5-1, RedHat 7.2 DCO2 is not the latest release, but from somwhere this summer (fromCVS). Thanks, /dario - -------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

XRON problem
by Ria Marinussen 26 Feb '03

26 Feb '03

Hi all, I try to periodically gather information about pages from which the set "expiration date" lies within the next week. I wrote a Python script that gathers the information and writes it to the server, and sends out a notifying e-mail with the link to the output on the zope server. The script works as I hoped it would. However, I'm trying to schedule it with XRON. The script gets triggered, the file gets written, the mail gets send. But The result is not what I had hoped. The information that should be gathered is missing, only an almost empty file gets created. During testing I noticed that when using the "View" tab of the Xron Method everything works OK, but when I use the "Trigger" tab to trigger the Xron event I have no meaningfull output. Zope version: (Zope 2.4.3 (source release, python 2.1, linux2), python 2.1.2, sunos5) Xron version: 0-0-10 Does anyone know what I can do to make this work? Thanks in advance, Ria Marinussen Webmaster INF University of Twente Enschede The Netherlands.

Manager DN Specification
by Krishna 26 Feb '03

26 Feb '03

Thanks for your help !! ... With the information you gave me I could authenticate / add and delete users. Below is the complete list of LDAP ACLs I have currently active. ************************************************** defaultaccess read access to dn="ou=People,dc=mysite,dc=com" by dn="uid=zeo,ou=People,dc=mysite,dc=com" write by * read access to dn="ou=zope-grps,dc=mysite,dc=com" by dn="uid=zeo,ou=People,dc=mysite,dc=com" write by * read access to filter="objectclass=cdObject" by dn="uid=zeo,ou=People,dc=mysite,dc=com" write by * read access to attr=userpassword by self write by * read access to * by * read ********************************************************* I also provided the Manager Dn in the LDAP user folder as... cn=Manager,dc=mysite,dc=com Now with all these settings i can successfully add / modify / delete / authenticate the relevant users. But what I need to know is .....do we need the Manager DN/passwd within the LDAP user folder??... In fact, the manager should only be used for server administrative tasks, we use it to get system account information into the LDAP directory. I need to know if there is a way for me to achieve the same WITHOUT specifying the Manager DN within the LDAPUserFolder !!!! .... would be helpful if I get some guidance :-) ...!!!! Thanks once again, Kris :-)

ZServer & OpenSSL
by Samir Mishra 26 Feb '03

26 Feb '03

I integrated ZServer & SSL and everything seems to be going OK except that I'm getting a lot of the following errors (from DEBUG mode in console) - 2003-02-26T13:38:45 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3291 at 0x2d061bc channel#: 104 requests:> bad write retry ------ 2003-02-26T13:38:48 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3292 at 0x2d15764 channel#: 105 requests:> bad write retry ------ 2003-02-26T13:38:52 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3293 at 0x2da6c6c channel#: 106 requests:> bad write retry ------ 2003-02-26T13:40:04 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3290 at 0x2d7ea9c channel#: 103 requests:> bad write retry ------ 2003-02-26T13:40:12 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3294 at 0x2db445c channel#: 107 requests:> unexpected eof ------ 2003-02-26T13:41:57 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3296 at 0x218fd24 channel#: 109 requests:> bad write retry ------ 2003-02-26T13:42:02 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3295 at 0x2adb7bc channel#: 108 requests:> bad write retry ------ 2003-02-26T13:42:07 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3299 at 0x2ca68d4 channel#: 112 requests:> bad write retry ------ 2003-02-26T13:42:11 INFO(0) ZServer recv: closing channel <ZServer.HTTPS_Server.zhttps_channel connected 131.70.10.82:3300 at 0x2b575fc channel#: 113 requests:> bad write retry etc. I'm getting a LOT of "unexpected eof" & "bad write retry" error messages. The former is OK, the latter makes the client browser hang. Anybody else experience this before? Any suggestions? I'm running Zope on Win32/XP with OpenSSL. Thanks. Samir.

Variable interpolation / string embedding in Python script?
by Jon Whitener 26 Feb '03

26 Feb '03

In Zope Page Templates, you can insert a variable into a path expression like: here/folder/?id Where 'id' is evaluated before the path expression is. It's great for repeat structures. Is there a similar mechanism for use in a Python Script? Something like context.?id.method() I haven't had any luck finding it, if it exists. Thanks in advance, Jon Whitener Detroit Michigan USA

Managing permissions & Security
by Samir Mishra 26 Feb '03

26 Feb '03

Hello all, Hoping for some help on permissions & security. I have a root folder defined as UserFolder. Within UserFolder, I've defined 3 additional roles of FolderManager, Author & Reviewer. None of the permissions are acquired from parent, Author, Reviewer & FolderManager roles have appropriate explicit permission settings. Manager has been granted ALL permissions. FolderManager has been granted only the following permissions (below) - Access Transient Objects Access arbitrary user session data Access contents information Add Folders Access session data Add Forum posting Add MetaEntrys Add User Folders Change ExtFile/ExtImage Change Local File System properties Change MetaPublisher FTP access List folder contents Log Site Errors Mail forgotten password Manage users MetaPublisher: Add Entry MetaPublisher: Edit Entry MetaPublisher: List Entries MetaPublisher: Manage MetaPublisher: Search Entries Overwrite local files Query Vocabulary Set Own Password View View Forum View management screens query No "local roles" have been defined. What I'm trying to do is create a user within the UserFolder who has permission to grant access to other users from the management screen. I.e., the FolderManager should be able to grant access to other users as either (Authenticated, Author, Reviewer) by updating the User Folder with additional usernames. The problem I'm having is that I find the FolderManager can create a user with a role of "Manager' and this user will then have the ability to change any of the permissions - permissions not originally available to FolderManager. Question - 1) how do I allow the FolderManager to create users with ONLY one of the following roles - Authenticated, Author, Reviewer - and exclude them from creating users with the Manager role? Can this be done through the normal management views? 2) Is there a better way of achieving this - creating a user within a folder who has the ability to add/delete users in other roles, but cannot assign themselves to any other role but of FolderManager? If any of the above is confusing PLEASE let me know, as I'm in a real twist over how to change this behaviour. Thanks in advance. Regards, Samir.
