ExtFile 1.2.0 copying
by Ryan T. Bard 05 Jun '04

05 Jun '04

In general, I have existing files that are part of a yearly curriculum. I need to be able to copy them so that a file can be used from academic year to academic year with any changes to that file for a given year only occur to that year's file instance. Any ideas how I would go about creating a new ExtFile object while using an existing ExtFile object as the file's source? Can this be done in a DtmlMethod or must I use a python script or external script to pull this off? When I try to point to an existing ExtFile object as the file argument in order to force a _copy call, I get an error. Maybe I am referencing the ExtFile object incorrectly; however, the fact that the error indicates a problem with the _copy call itself lends me to believe that the error lies elsewhere. Details: The syntax for adding an ExtFile to Zope is manage_addExtFile, with four arguments: id, title, description, file. In this example I have an ExtFile object in a folder called "files", which lies in the folder "Test". This DtmlMethod is being called from the Test folder as well. I have even gone as far as to set Proxy permission to Manager just to see if it is a permissions issue, with no change. In a DtmlMethod I have: <dtml-call "Test.manage_addProduct['ExtFile'].manage_addExtFile('tempfile', '', '', Test.files['instructions.doc'])"> I get an Attribute Error with the following partial stack trace: (Object: Test.manage_addProduct['ExtFile'].manage_addExtFile('tempfile', '', '', Test.files['instructions.doc'])) (Info: Test) File <string>, line 2, in f File Zope/lib/python/Products/ExtFile/ExtFile.py, line 101, in manage_addExtFile (Object: Test) File Zope/lib/python/Products/ExtFile/ExtFile.py, line 371, in manage_file_upload (Object: tempfile) File Zope/lib/python/Products/ExtFile/ExtFile.py, line 488, in _copy (Object: tempfile) AttributeError: read Does it seem to be something I am doing? A problem with the ExtFile product itself, perhaps? Any ideas? Thanks! -- Ryan T. Bard Webmaster/Software Developer Department of Medical Education University of Miami School of Medicine

Group mapping not working on LDAPUserFolder
by Josef Meile 05 Jun '04

05 Jun '04

Hi, I just found that the group mapping isn't working for our LDAP. I tried with the LDAPUserFolder 2.4beta2 and CookieCrumbler 1-1. I could authentificate myself against the LDAP, search some users, and I could also see the groups, but the group mapping (on the groups tab) didn't work. This is what I have: 1) We have an extra attribute for the LDAP Schema: LDAP Attribute Name: ou Friendly Name: group Multi-valued: Yes This attribute gives us a list of groups to which a user belongs to. The rest configuration for the LDAP is quite normal: Login Name Attribute: uid RDN Attribute: uid Users Base DN: ou=grp1,ou=grp2,ou=grp3,ou=grp4,o=org,c=country Scope: SUBTREE Group storage: Groups stored on LDAP server Groups Base DN: cn=foo_account,ou=admins,ou=grp3,ou=grp4,o=org,c=country Password: xxxxxx Manager DN Usage: Always Read-only checked User password encryption: SSHA Default User Roles: LDAP=Anonymous LDAP Servers: my_ldap.mydomain.com, port: 636, LDAP over SSL 2) Group mapping on the LDAPUserFolder's "groups" Tab: "foo_group" maps to zope role "Manager" 3) Tried the following PageTemplate to authenticate my self on the LDAP (it prints the roles I have over the request): User: <p tal:replace="python:user.getUserName()"></p><br> Roles: <p tal:replace="python:user.getRolesInContext(here)"></p><br> <p tal:condition="python:user.getUserName()=='Anonymous User'"> you aren't logged in </p> <span tal:condition="python:user.getUserName()=='Anonymous User'"> <span tal:condition="python:request.has_key('firstTime')"> <h1>Login error</h1> <br><br> This user name isn't valid.<br> Perhaps your browser doesn't has cookies enabled. <br><br> </span> <span tal:condition="python:not request.has_key('firstTime')"> <h1> For the following pages you need to login. </h1> </span> <table> <tr> <td> <form method="post" name="loginForm" action="some_url" tal:attributes="action python:request.URL0"> <input type="hidden" name="firstTime" value="0"> <table cellspacing="10"> <tr> <td align="left" valign="top" width="170"> <font face="verdana"><strong>login:</strong></font> </td> <td align="left" valign="top"> <input type="TEXT" name="__ac_name" size="20" class="text" value="" tal:attributes="value python:request.get('__ac_name','')"> </td> </tr> <tr> <td align="left" valign="top"> <font face="verdana"><strong>password:</strong></font> </td> <td align="left" valign="top"> <input type="PASSWORD" name="__ac_password" size="20" class="text"> </td> </tr> <tr> <td align="right" colspan="2"> <input type="submit" value=" Login " class="button"> </td> </tr> </table> </form> </td> <td> <p> Login problems?<br> Perhaps your browser has cookies disabled </p> </td> </tr> </table> </span> I can authenticate myself against the LDAP, but What I get when printing the roles is: User: my_login_name Roles: ['Anonymous', 'Authenticated'] "my_login_name" belongs the foo_group and other groups as well, but It doesn't get the 'Manager' role as expected. Then, I found that line 333 of LDAPUserFolder.py (method _lookupuserbyattr): groups = list(self.getGroups(dn=dn, attr='cn', pwd=user_pwd)) doesn't return any group for this user, so, I replaced it for: groups = user_attrs.get('ou',None) if groups==None: groups = list(self.getGroups(dn=dn, attr='cn', pwd=user_pwd)) and now it works. I think this is possible on our case because of the additional "ou" attribute, but would it work on other configurations? Is this only happening to me, or is it a bug? Regards, Josef

Zope X3 3.0.0 beta 1 released
by Stephan Richter 04 Jun '04

04 Jun '04

Dear Zope community, The Zope 3 development team is proud to announce the first beta release of Zope X3 3.0.0. Zope X3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. The "X" in the name stands for "experimental", since this release does not try to provide any backward-compatibility to Zope 2. Download http://zope.org/Products/ZopeX3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt of the distribution. Changes to alpha 2 - More packages have been removed from the distribution. This includes the 'session' package and all the packages that deal with Python code inside the ZODB, such as 'zodbcode' and persistent interfaces. - Complete reimplementation of the event system to use subscribers. - Updated the online help system (not to be confused with API doc tool) to reflect the latest APIs and design patterns. - The access log can now be configured via the 'zope.conf' file. - The underlying component lookup machinery has been overhauled. Every Zope thread now knows automatically about the context. This simplified the component lookup API a lot. - Several bug fixes. - The Russian translation was completed and the German one was updated as well. Goals The API is frozen now for X3.0.0. We would like to ask all people to test this release and report any bugs or mis-behaviors! The beta period is scheduled to last for about 1 month. During this month we will try to complete the following tasks: - Fix outstanding bugs. - Optimize critical components to speed up the system. - Write and update documentation. - Add and complete translations. - Remove as many XXX comments as possible. There is still much to do! Even if you are not a programmer, you can help! Please send any bug reports and comments to zope3-dev(a)zope.org! Thank you very much in advance for your help! Contributors Jim Fulton, Marius Gedminas, Fred Drake, Philipp von Weitershausen, Stephan Richter, Dmitry Vasiliev, Scott Pascoe, Bjorn Tillenius, Eckart Hertzler, Roger Ineichen, Stuart Bishop Thanks to everyone!

TextIndexNG and Word doc
by NKUNDABAGENZI Fabien 04 Jun '04

04 Jun '04

Hi all, I just noticed a problem with TextIndexNG. I'm running zope-2.6.2, with Plone 1.05 and TextIndexNG-2.05 on a RedHat distribution. Wvware and pdftotext are installed as well. When I run the server in Debug mode, there is no problem. All pdf and word documents are indexed. But once the server is ran normally (no debug mode), TextIndexNG works fine with the pdf files, but don't index word documents. There are no error messages and since the problem only occur when we aren't running on debug, it's not easy to find out what's going on. Thanks for any suggestions !

Running zope single threaded fixes memory leaks and frequent sigsegv(11) restarts.
by Richard Ettema 04 Jun '04

04 Jun '04

Hi, This combines two previous questions about problems I have been experiencing with large memory leaks and also lately zope being restarted regularly by a sigsegv(11) signal. Both of these issues have been "fixed" by running zope on our production server with a single thread. We are currently running zope 2.6.2, python 2.1.3, on debian stable. The memory leak problem could be reproduced on the dev server but the sigsegv problem could not be reproduced. Running the dev box single threaded did fix the leak problem there as well though. The dev box is due to be upgraded to zope 2.7 and python 2.3 but is there anything I should be looking at that could be the cause of these problems? I have done a lot of searching but have not found many clues to the next step other than upgrade zope. The page I read about running single threaded suggests a C extension being a likely cause. I have been reading up on creating c extensions for python, but how do you track down where/when existing python code makes use of a c extension? Being new to the debugging side of things, can someone give suggestions on links/info on simple explanations of debuggers and how best to use them to solve such an issue as I have here. Thanks for your help. Richard.

Autologin
by Peter Bengtsson 04 Jun '04

04 Jun '04

I've got a basic folderish python product where its instances will by default have the View permission switched off, so you get bugger all unless you authenticate yourself. By saving the username and password in Mozilla/IE/... it just requires an Enter touch when the login dialog appears; but I don't even want that to appear. I want it to work like Sourceforge does where it remembers my whole login without any authentication on each visit. What tools/hacks are available to achieve this? -- Peter Bengtsson, http://www.peterbe.com

Updating content from one Zope instance to another
by David Chandek-Stark 04 Jun '04

04 Jun '04

I want to run a development -> production system with two CMF sites and am looking for advice on how to do this. Should I run two CMF sites in the same ZODB, and write a script to update production content from development content? This system is an interim solution on the road to adoption of Zope4Edu. We're under a rigid deadline and staff resources are thin due to other demands. The content of the site lives in Page Templates, not portal content objects (I'm mainly using CMF for portal_skins) and there's no workflow. This probably wasn't the best way to do it, but it seemed easier to do everything "by hand". The main problem is, I'm worried about developers frequently breaking pages due to ZPT compilation errors and would prefer have changes made and tested on the development system, then copied to production (either manually or automatically). We are using Dreamweaver over WebDAV and can do XML validation there (we're standardizing on XHTML 1.0 transitional). Hopefully that will catch most problems, but ... I'd appreciate any thoughts, advice, links. -- David Chandek-Stark Web Applications Developer Duke University - Perkins Library (919) 660-5859 dc(a)duke.edu

Handling object changes
by Santi Camps 04 Jun '04

04 Jun '04

Hi all, I'm looking for some method to handle changes on my objects. I'm interested in persistence changes. I know I should be able to handle some changes writting a __setattr__ method, but I'm also interested into handle changes even if they are done in a list attribute, or in a dictionary attribute. That's it, I would be able to handle any changed market in the "self._p_changed = 1" way, but I'm not able to find the piece of code doing this work. Anybody knows if it is possible ? If not, anybody knows where is the logic doing this work in Zope (Connection, Storage, Persistence, ...) ? Thanks in advance Santi Camps
