Zwiki contributor policy update
by Simon Michael 11 Dec '05

11 Dec '05

Hi all! I'm slightly burned out and bored with certain areas of Zope 2 Zwiki development. I think the product will provide some value for a while yet, and it's not too late to shake things up and make a bigger splash. If we don't do this during the period of Zwiki & Zope 2's relevance, our good work will bring less benefit than it might have. So I'm putting out a call for help. I'd really like to see more people take on development of Zwiki. What are the roadblocks - of my making, and otherwise - to a more active Zwiki developer community ? For one thing I needed to nail down some copyright/license issues more explicitly, to make contributing and accepting contributions more of a no-brainer. Here's my latest thinking: LICENSE Much Zope code uses the ZPL. We want to maximize code sharing and participation with the whole Zope community. Much of the rest of the FOSS world uses the GPL, and the same goes for them. Dual GPL/ZPL licensing may seem a good option, but I'm convinced it's not worth the added complexity, legal uncertainty and fragmentation; either straight GPL or straight ZPL is preferable. GPL is the mainstream license for the future IMHO, I think it's still the best option, and I have no plan to leave it. Also I think we should adopt GPLv3? <http://zwiki.org/PolicyAnnouncementDraft/createform?page=GPLv3> when it's ready. That said, there's now clear policy allowing non-GPL code to be added to Zwiki if necessary (below). Also I remain open to license exemption requests from Zope developers. COPYRIGHT I no longer think the single copyright holder policy is best for this project, and I'm going to drop it. I am changing the main repo's policy to multiple copyright holders (& allowing multiple licenses), with the simple condition that the overall project manager is assigned the right to relicense to newer license versions. The powerful darcs revision control system (together with new CONTRIBUTORS list) should help us to keep track of copyright & licensing status and even remove problematic commits later if needed. CONTRIBUTOR'S AGREEMENT To ensure that everyone gets proper credit for their work; a clear audit trail and legal status for the project; and that the project can remain license-compatible with other free & open-source software in future, I have added a very simple contributor agreement/contributor list: http://zwiki.org/repos/ZWiki/CONTRIBUTORS.txt . All Zwiki contributors should read and consider signing this file, to help us meet these goals. You can follow this easy procedure to add your name to the glorious list: (install darcs if needed, see http://darcs.net/DarcsWiki/CategoryBinaries) darcs get --partial http://zwiki.org/repos/ZWiki cd ZWiki echo "- Your Name <your@email>" >>CONTRIBUTORS.txt darcs record -a -m"signed it" CONTRIBUTORS.txt (enter your name & email address again) darcs send This will become the authoritative list of code committers (at least), and I'll be working to make sure all of you are listed properly. Many have donated their time and creativity over the years - this list will make that clearer. All comments, help and other ideas welcome. And I hope to see some of you online or off. Happy holidays, and thanks -Simon

resolving conflict errors
by Dennis Allison 10 Dec '05

10 Dec '05

Zope 2.7.6 I am a bit confused. I have a Zope DTML method that is generating ZODB conflict errors. The DTML method identified as producing the conflicts is a list of calls to other methods, conditionally executed. Most conflicts don't cause problems because the backoff and restart of the initial transaction will not have changed global state. In our particular case, the conflicting transaction has changed global state in our RDBMS so when it gets rerun, some RDBMS transactions are duplicated. And that's a problem. The solution, of course, is to resolve the conflicts properly. The first question: what data is generating the conflict? The DTML code and all the method references are static and unchanged. What data does Zope store in the ZODB when an object is evaluated? Presumably conflicts can be reolved programatically by setting a method on the object _p_resolveConflict( self, old, saved, new ) and returning one or another of the states (old, saved, new). It's not real clear how to do it. --

We expect papers from both academicians and practitioners, in all subjects related to Enterprise Information Systems and Enterprise Resources Planning. Authors that do not focus their work specifically in free/open source software can submit to Confenis 2006. Elsevier will publish proceedings of both events and best papers will be also published by top ranking IEEE and ACM periodicals. More information is available at http://www.confenis.org. About the IFIP: The IFIP (International Federation for Information Processing) was created in 1960 under the auspicious of UNESCO; it aggregates the main computer societies worldwide, including the ACM and IEEE. It is responsible for the realization of top ranking conferences like IFIP/W3C/ACM International World Wide Web Conference and IEEE/ACM/IFIP International Conference on Hardware/Software Codesign & System Synthesis. More information about IFIP is available at http://www.ifip.or.at/ About the IFIP TC8: The IFIP Technical Committee 8 Information Systems is divided in many subcommittees, each one for a specific IS area: · WG 8.1 Design and Evaluation of Information Systems · WG 8.2 Interaction of Information Systems and the Organization · WG 8.3 Decision Support Systems · WG 8.4 E-Business: Multi-disciplinary research and practice · WG 8.5 Information Systems in Public Administration · WG 8.6 Transfer and Diffusion of Information Technology · WG 8.8 Smart Cards At http://ifiptc8.itu.dk/ more information can be found about the IFIP TC8.

Broken Pipe Error

I am using Maik Jablonski's python script to convert from html to pdf in conjunction with the htmldoc product. FYI, I am running Mac OS X Tiger. When I run the script, I get the following error which is being generated by line 20 of the script: IOError: [Errno 32] Broken pipe line 20 is as follows: stin.write(html) The script is as follows: import AccessControl, os def html2pdf(self): """ html2pdf converts a HTML-Page to a PDF-Document """ securityContext=AccessControl.getSecurityManager() if securityContext.checkPermission('View', self): if self.meta_type=='Folder': html = self.index_html(self,self.REQUEST,self.REQUEST.RESPONSE) else: html = self(self,self.REQUEST,self.REQUEST.RESPONSE) (stin,stout) = os.popen2('htmldoc --footer " : " --webpage -t pdf --quiet --jpeg -') stin.write(html) stin.close() pdf = stout.read() stout.close() self.REQUEST.RESPONSE.setHeader('Content-type','application/pdf') self.REQUEST.RESPONSE.setHeader('Content-disposition','inline; filename="%s.pdf"' % (self.getId())) return pdf else: raise AccessControl.Unauthorized Any help would be appreciated.

No, you can just delete the instance directory. It's the copying that is the problem. The Data.fs can generally be copied without problems though. -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/
