Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

Hello list, I want to run the database in read-only mode from CD and configured it accordingly in the zope.conf: read-only-database on enable-product-installation off zserver-read-only-mode on Starting Zope, I get the following error: Traceback (most recent call last): File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 56, in ? run() File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 21, in run starter.prepare() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 98, in pre pare self.startZope() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 257, in st artZope Zope2.startup() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 47, in sta rtup starter.setConfiguration(cfg) File "D:\Programme\Zope\lib\python\Zope2\App\startup.py", line 56, in startup File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 96, in getDatabase File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 113, in _createDataba se File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 163, in o pen DB = self.createDB() File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 160, in c reateDB return ZODBDatabase.open(self) File "D:\Programme\Zope\lib\python\ZODB\config.py", line 97, in open File "D:\Programme\Zope\lib\python\ZODB\config.py", line 133, in open File "D:\Programme\Zope\lib\python\ZODB\FileStorage\FileStorage.py", line 112, in __init__ File "D:\Programme\Zope\lib\python\ZODB\lock_file.py", line 57, in __init__ IOError: [Errno 13] Permission denied: '\\Zope-Instance/var/Data.fs.lock' r+ means opening the file for updating. This has not to do anything with read-only. Does anybody know what I have to configure additionaly, that read-only works? I run Zope 2.8.4 on windows. Many thanks in advance, Ulla.

ZopeProfiler and Kcachegrind, how to convert statistics files ?
by Jean-Michel FRANCOIS 03 Feb '09

03 Feb '09

Is someone has try to use ZopeProfiler with KCacheGrind ? I would like to try KCachegrind because i found xdot very slow. I have started to read the code of ZopeProfiler and i have discovered the world of profiling file format. It seems that ZopeProfiler save it's file in pstats format. So i need to convert those file to calltree format. But all scripts i have tryed has failed: * pyprof2calltree * lsprofcalltree.py * hotshot2calltree So am i on the wrong way ? Do i need to fix one of these script ? Are you using on of them ? Thanks. JeanMichel FRANCOIS Makina-Corpus

Zope 3.4.0 Released!
by Stephan Richter 02 Feb '09

02 Feb '09

Hi everyone, It is finally here! Thanks goes to everyone who involved! January 29, 2009 - The Zope 3 development team announces the Zope 3.4.0 release. After 2 years of development, the Zope Foundation and the larger Zope community is proud to announce the release of Zope 3.4.0. The focus of the Zope 3.4 development effort has been the conversion from a monolithic source tree, to a set of many small packages (eggs), that can be used independently of each other. The core has been further stabilized through numerous bug fixes, and many new add-on packages have been developed to provide a richer development experience. With this release also comes a renewed commitment to a short and reliable release cycle of 6 months. Packages and Eggs ----------------- Zope 3 is now fully converted to an egg-based system. While some work still remains, it integrates very well with the rest of the Python community. The conversion to egg-based packaging also enables other Python developers to only have to use small bits and pieces of the complete Zope software system. The conversion means that Zope 3 developers do not use the classic Zope 3 tar-ball release anymore. However, for your convenience, Zope 3 developers will provide the classic Zope 3 tar ball releases for at least the 3.4 series and probably for 3.5 as well. So how are Zope 3 applications built using only eggs? The Known Good Set (KGS) ~~~~~~~~~~~~~~~~~~~~~~~~ The known good set -- or in short KGS -- is a configuration of packages and their versions that are known to work well together. The compatibility is frequently verified by running over twelve thousand tests on a daily basis [1]_. The KGS is tested against Python 2.4 and 2.5 on the 32- and 64-bit platforms. The list of controlled packages and their versions for Zope 3.4 can be found at the Zope 3 KGS site [2]_. The KGS can be used in several ways [3]_. The most common way is to "nail" the versions by downloading the version configuration file [4]_ and insert them as follows in your buildout configuration:: [buildout] versions = versions ... [versions] zope.interface = 3.4.0 ... ``zopeproject`` Project Builder ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To start building a project using a common setup, a package called `zopeproject` can be used to quickly setup the boilerplate for the project. Ample documentation is provided at the `zopeproject` home page [5]_. `zopeproject` uses Paste or ZDaemon to create a working server. The following commands get you started:: $ easy_install zopeproject $ zopeproject HelloWorld $ cd HelloWorld $ bin/helloworld-ctl foreground Demo Packages ~~~~~~~~~~~~~ At this point, there is no demo package demonstrating a simple Zope 3 application setup. However, the ``z3c.formdemo`` package can be used as a fairly minimal setup. To get started with it, enter the following:: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/tags/1.5.3 formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -v $ ./bin/demo fg ..

The binary installer is recommended for Windows. Zope 3.4 requires Python 2.4 or 3.5 to run. You must also have zlib installed on your system.

It was rewritten from scratch based on the latest software design patterns and the experiences of Zope 2. The component architecture is the very core of Zope 3 that allows developers to create flexible and powerful web applications. Compatibility with Zope 2 ~~~~~~~~~~~~~~~~~~~~~~~~~ Zope 3 is not upwards compatible with Zope 2. This means you cannot run Zope 2 applications in Zope 3. We continue to work on the transition from Zope 2 to Zope 3 by making Zope 2 use more and more of the Zope 3 infrastructure. This means that new code written in Zope 2 can benefit from Zope 3 technology. Also, with care, code can be written that works in both Zope 3 and Zope 2. This allows a Zope 2 application to slowly evolve towards Zope 3. Unchanged Zope 2 applications are never expected to work in Zope 3, however. About the Zope Foundation ------------------------- The Zope Foundation, based in Fredricksburg, Virginia, is a not-for-profit organisation that provides support for the Zope community and the Zope platform and its associated software. Its community includes the open source community of contributers as well as the community of businesses and organizations that use Zope.

31 Jan '09

Hi folks, The deadline for the O'Reilly Open Source Convention Call For Participation is Tuesday Feb 3rd. OSCON will be held July 20-24 in San Jose, California. As of today, there are no Zope-related proposals, so yours could have a pretty good chance of acceptance. ;-) There have been a lot of exciting developments in the Zope world in the past year, and I for one would really like Zope to get more public exposure. So please, write up your proposals and submit them before the deadline! For more information, see http://conferences.oreilly.com/oscon http://en.oreilly.com/oscon2009/public/cfp/57 Cheers, - Michael Bernstein

calling satisfied Zwiki users

Forwarding this to the Zwiki and ex-Zwiki diaspora. Thanks all! -Simon On Jan 28, 2009, at 3:00 PM, Simon Michael wrote: Marketing.. sure, why not. New Zwiki users are still showing up and a little more marketing wouldn't hurt. I think some of us enjoy using Zwiki and I've thought about collecting some testimonials/quotes. I know when I see a project that has realistic testimonials from happy users, that really helps motivate me to try it out. I don't have much sense of how large/active/plugged in to this page the Zwiki-using community is, but if you are reading this, are happy with the software and can write a short testimonial, please send it. Don't wait, just hit reply now! :) Testimonials are like a micro-review, typically a short quote. (Longer reviews are of course welcome too!) They should come from your real experience with Zwiki, and be honest (negative reviews are also useful.) Include the name you'd like to appear with the quote; the strongest testimonials include a real full name and organization. You might mention whether you are using Zwiki with or without Plone. If I can collect enough positive ones, I'll start rotating them on the zwiki.org home page. -- forwarded from http://zwiki.org/GeneralDiscussion#msg5B888B82-B2DC-4C76-8007-18D87C7BAB05@…

declarePublic function
by Milos Prudek 28 Jan '09

28 Jan '09

I would like to upgrade my site from Zope 2.7.x to Zope 2.10.x When I try to run my site under Zope 2.10.x, I get this exception: class JMZPTMacros: File "/home/orl/Zope/Products/JMZPTMacros/JMZPTMacros.py", line 28, in JMZPTMacros security.declarePublic() TypeError: declarePublic() takes at least 2 arguments (1 given) I need to use JMZPTMacros. It is an old product that seems to require a patch to line 28. I can see that Zope 2.7.x defines declarePublic() as: def declarePublic(self, *names): and that Zope 2.10.x defines declarePublic() as: def declarePublic(self, name, *names): therefore I understand that one parameter is obligatory. But I cannot guess what parameter it should be for JMZPTMacros. I tried to look how declarePublic is used inside Zope but it gave me no clue. Please help. -- Milos Prudek

What am I getting with a plone windows installer?
by Joseph Thomas (s) 27 Jan '09

27 Jan '09

I recently installed plone from plone.org, just curious what's the difference between the python installation that's bundle with plone and/or zope and a stand-alone python installation? Can I use the bundled python installation as the base for other applications that need python, like wxPython?
