PluggableAuthService question about roles
by Thomas Bennett 03 Apr '07

03 Apr '07

I have installed the following: Zope Version (Zope 2.9.7-final, python 2.4.4, linux2) Python Version 2.4.4 (#1, Oct 23 2006, 13:58:00) [GCC 4.1.1 20061011 (Red Hat 4.1.1-30)] System Platform linux2 SOFTWARE_HOME /var/zope/lib/python ZOPE_HOME /var/zope INSTANCE_HOME /var/zope CLIENT_HOME /var/zope/var Network Services ZServer.HTTPServer.zhttp_server (Port: 8086) ZServer.HTTPServer.zwebdav_server (Port: 9800) I'm using Zeo storage with this. The main problem is my understanding roles with my new set up. I am moving from a Zope 2.6.1 setup to the setup shown above. I've already added some Products to my INSTANCE_HOME/Products directory including Plone which includes the PluggableAuthService folder. I installed a Plone site for testing and deleted it. It appears that PAS has taken over my root acl_users folder or is this now a default in 2.9. Now I can only add users from the ZODB User Manager under /acl_users/users, there is nowhere to add a user from an Add buttion as in the older version of Zope. I can add roles from ZODB Role Manager in /acl_users/roles but these roles don't show up under the Security tab on any page. I can add local roles under the Security tab and they don't show up in /acl_users/roles. I have searched and can find little to no documentation on use or difference in the two authentication methods. Where can I find more information on roles in 2.9.7 and use in this situation? Is this normal behavior and if so how can I synchronize roles between the Security tab and /acl_users/roles or is it not possible? Am still searching the WEB and archives in the meantime.

All Of My Zope 2.6 Transactions Since 2/6/07 Are Gone!
by Mark, Jonathan (Integic) 03 Apr '07

03 Apr '07

Zope 2.6.2 on Red Hat 7.3 started acting flaky a week or two ago. It started dying every day or so. Then it lost all transactions since 2/6/07, displaying content as it was two months ago. Then it recovered the lost content, now it has lost it again. Zope Undo shows incorrectly that there were no transactions between 2/6/07 and 3/28/07 when the data loss occurred. What is the best approach to getting this data back?

about LocalFS
by Alan 02 Apr '07

02 Apr '07

Dears, Just checking and maybe looking for some advices. My application in Zope depends on LocalFS. I want to make my application reproducible at other Zope servers. My question is if LocalFS is still maintained and under developed and if so is there any other version newer than http://www.easyleading.org/Downloads/LocalFS-1.7rc1-andreas.tar.gz/view? In order to still use LocalFS I need to hack in its code and it's not such a thing I would like to request to another user to do if he/she wants to do my application. If I have to move from LocalFS, which other product would replace it keeping at least LocalFS features? Many thanks in advance. Regards, Alan

ZSQL, call for early beta testers
by Peter Bengtsson 02 Apr '07

02 Apr '07

I've developed a little module that makes it really easy to plug in .sql files into a python product class as ZSQLMethods. It's extremely easy to use and doesn't require any CMF or ZODB stuff. It also has support for memcache for those of you with slow db queries that you need to repeat. It works something like this:: from Products.ZSQL import initializeSQLfiles class _SQLBase(Acquisition.Implicit): dbConnection = 'Psycopg_database_connection' class SQLUser(_SQLBase): pass folders2classes = {'sql/Userstuff': SQLUser} home = package_home(globals()) initializeSQLfiles(folders2classes, home) If in the folder 'sql/Userstuff' you have a file called 'select_users.sql' you will the be able to just run: # select users: print SQLUser.select_users() # same but first printed the final SQL used print SQLUser.select_users(debug__=True) # save time for the next call print SQLUser.select_users(memcache__=True) Is anybody interested in a being early beta testers before I release it as Open Source? It works quite well here for me but I fear I'm getitng a bit home blind based on just my needs. I'm pretty sure it works but some early feedback would be appreciated.

include?
by Katie 02 Apr '07

02 Apr '07

We're almost finished getting the new site done completely in zope using css and mySql. We have an older portion of the old site done in php thought that we don't really want to re-write. We'd like to include it in the dtml document page that has all the common elements of every page but I'm at a loss of a way to do it other than using an inline frame. Is there a dtml include that takes a url string the way the <dtml-var> tag renders the associated file? Katie

z3c.rml 0.5 released!
by Stephan Richter 02 Apr '07

02 Apr '07

Hi everyone, I am very proud to announce the release of z3c.rml version 0.5, an independent implementation of the ReportLab Markup Language (RML). RML is a XML dialect that describes the generation of a PDF using the ReportLab PDF generation library. This release focuses on compatibility with the RML version developed by ReportLab, Inc. In the future, however, the plan is to divert from the original API to fix inconsistencies between the RML Specification and the ReportLab API and to extend beyond the original functionality. Features -------- - Full support of all common RML directives. - Support for merging in pages from external PDF files thanks to pyPdf. - Directives are fully documented using an extension to Zope's interfaces and schemas. - Code-generated DTD file. - Code-generated RML Reference document, of course as PDF built with z3c.rml. - Optional integration of page templates, allowing dynamic RML documents to be created. - Support for charts. - Test suite with 90 files. Roadmap to 1.0 -------------- - Fix inconsistencies between ReportLab and RML APIs. - Finish the documentation of the chart support. - Finish the page insert and merge functionality. - Improve the DTD generator and possibly write a generator for RelaxNG. - Integration of a hyphenation support, if a proper package can be found. Installation ------------ z3c.rml has been uploaded to the Python cheese shop. Thus you should only need to say: easy_install z3c.rml Unfortunately, easy install will not install the ``reportlab`` dependency, since it is not available in the cheese shop. This will have to be done by hand. Also, by default the pagetemplate support is not enabled, because of the many dependencies. However, if you want the pagetemplate support, you can simply install it or install the "zope.pagetemplate" egg. Questions and Comments ---------------------- If you have any questions or comments, please feel free to contact the Zope 3 Users mailing list at zope3-users(a)zope.org or E-mail me directly at srichter(a)cosmos.phy.tufts.edu. Enjoy! Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training

getting a unique object id
by David Bear 30 Mar '07

30 Mar '07

I am needing to write an external cache mechanism for rss feeds from zope/plone. My thinking was to use feedparser, then grab the set of object attributes for the item from zope. Then, grab the actual document the feed pointed to and save it. When naming the document that I store locally, I was looking for a simple way to map the zope objectId to the file name hoping it would be unique. However, if this is not unique, is there another attribute from a zope object that I can get that would be? If so, how would I get it? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

Problem with __before_publishing_traverse__
by Peter Bengtsson 30 Mar '07

30 Mar '07

I have a product that looks like this:: class MyApp(Something): meta_type = 'x' def foobar(self): """ doc str """ return "xxx" def __before_publishing_traverse__(self, object, request=None): print "HOUSTON" index_html = PageTemplateFile(...) When I view objects of this class I'd expect Zope to call the __before_publishing_traverse__ hook and print HOUSTON, but it doesn't :( I started fiddling with /usr/lib/zope-2.8.8/lib/python/ZPublisher/BaseRequest.py to try to see what's going on. BEFORE (around line 269):: while 1: bpth = getattr(object, '__before_publishing_traverse__', None) if bpth is not None: bpth(object, self) path = request.path = request['TraversalRequestNameStack'] AFTER:: while 1: bpth = getattr(object, '__before_publishing_traverse__', None) if bpth is not None: bpth(object, self) if object.__class__.__name__ == 'MyApp': print object.foobar() print object.foobar print object.__before_publishing_traverse__(object, self) print bpth path = request.path = request['TraversalRequestNameStack'] When I look at the output of this I get: xxx <bound method MyApp.foobar of <MyApp at /IMS>> None This is on Zope 2.8.8 and I've never had problems with __before_publishing_traverse__ in Zope 2.8's before. Could it be that something in Zope 2.8.8 has changed? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

Announcing the Release of Zope version 2.8.9.1
by Tres Seaver 29 Mar '07

29 Mar '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.9.1. You can download the sources from "http://www.zope.org/Products/Zope/2.8.9.1/", http://www.zope.org/Products/Zope/2.8.9.1 This bugfix release corrects a problem introduced in 2.8.9, which prevented starting Zope in "background" / "daemonized" mode. New features of Zope 2.8.x - ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. - Integration of Zope 3 technologies through Five (see http://codespeak.net/z3/five/) More Information For more information on what is new in this release, see the CHANGES.txt files for the release: "http://www.zope.org/Products/Zope/2.8.9.1/CHANGES.txt", http://www.zope.org/Products/Zope/2.8.9.1/CHANGES.txt See also: "http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView" http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: "http://www.plope.com/Books/2_7Edition/InstallingZope.stx", http://www.plope.com/Books/2_7Edition/InstallingZope.stx Reporting Bugs Please report all the bugs you have found to the Zope bugtracker: "http://collector.zope.org/Zope", http://collector.zope.org/Zope Supported Python versions At this time the only **supported** and **recommended** Python versions are 2.3.5 and 2.3.6. Using Python 2.4.X is **not supported** and **not recommended** at this time. Python 2.4.X will be supported when a security audit takes place. This means that you are using Python 2.4 + Zope 2.8 at **your own risk**. This warning also applies to binary packages that install Zope packages ogether with a system wide Python 2.4 installation (e.g. Fedora, SuSE...). Such installations are in general not supported. In addition there some third-party products and Python packages that don't work with Python 2.4 and can cause trouble when using Python 2.4. - -- =================================================================== Tres Seaver +1 540-429-0999 tseaver(a)palladion.com Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGDCIL+gerLs4ltQ4RAjV8AJ4qc4gChSxhoDQC2E+l+5UbbTr2kgCgiDZf f23x570Y4wNvsWcS55QZ8+o= =CNr8 -----END PGP SIGNATURE-----
