Moving an application from Zope 2.8 to Zope 2.11
by Marco Bizzarri 17 Feb '09

17 Feb '09

Hi all. Following the advices I received about upgrading the current release of Zope, I'm moving an application from Zope 2.8 to Zope 2.11. I've already solve some minor issues with other Products I have, but now I would like to know how to handle this: I'm using Localizer inside the application, and TranslationService Product to proviide i18n namespace to PageTemplates. However, I think TransationService should not be used anymore in Zope 2.11, as there should be some other way to handle this stuff. Can anyone provide pointers? Regards Marco -- Marco Bizzarri http://notenotturne.blogspot.com/ http://iliveinpisa.blogspot.com/

With one client i have no problem. When there are 4/5 clients connected to update simoultanely, the plone freeze. ALL the system works very very slowly: all plone site in the same istance and the other plone sites in other istances too. There is some timeout to set up,or any other config to set? In etc/ zope.conf i haven't found anything about it. My extension is: def makeInsert(self, pagina, stringa, host, porta, accesso,content): import socket s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) hostname=host port = int(porta) s.connect((hostname, port)) data=s.send(str(content)) data = s.recv(1024) data = s.close() return repr(data) Thanks in advance Massimiliano

writing repozo messaging output to a file....
by michael nt milne 06 Feb '09

Would anyone know how to modify the repozo command to log output messages to a file? I realise that the 'v' flat displays messaging, however we're using a tool (VisualCron) which runs a series of commands and we are unable to view python output when this tool executes python commands... repozo -BvzQ -r /foo/backup -f /foo/Data.fs michael

zsync for zope 3.4 on windows
by Hoang-Vu PHUNG 04 Feb '09

04 Feb '09

Hi all, I read somewhere there is a tool called zsync for zope 3. I have installed zope 3.4 for python 2.5. My python 2.5 is in the folder c:\python2.5 and zope 3.4 was also installed in this folder (i believed because it automatically found the python2.5 installation directory and installed with asking). I do a search for zsync but can't find, please help me. Thanks, Rgds Vu

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.
