We sure have some products, but it should not crash the main system.

Going to 3.0
by Fernando Lujan 09 Jan '06

09 Jan '06

We use a Psycopg connection, and Z SQL Objects... We don't have any programs written in python that use zope interfaces and so on. We have a entire site written in DTML in Zope 2.x. Now, after some discuss here We want to migrate it to Zope3.x. and start to develop using the zope 3 facilities and OO and ZPT. I already install Zope 3.1.0 and try to copy the Data.fs. But it produces a lot of erros. How can I handle this? Will exist a way to migrate from Zope 2.x to Zope 3.x? Thanks in advance. Fernando Lujan

Please keep this on the mailing list. What you are referring to is a use case Zope cannot cater for. To run a Zope server you must have certain levels of access to the server. Zope is not like a CGI-script that you can upload and run out of Apache, it is a full-blown server process on its own. This is neither an oversight nor a limitation, this requirement exists for all real server software you want to install and run. jens

Zope 3.2.0 released!
by Stephan Richter 08 Jan '06

08 Jan '06

Hello everyone, The Zope 3 development team is proud to announce Zope 3.2.0. Zope 3 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. It is our opinion that Zope 3 is more than ready for production use, which is why we decided to drop the 'X' for experimental from the name. We will also continue to work on making the transition between Zope 2 and Zope 3 as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in the form of Five. This is a long term effort. We're not there yet. **You can't run Zope 2 applications in Zope 3.** Downloads http://zope.org/Products/Zope3 Installation instructions for both Windows and Un*x/Linux are now available in the top level 'README.txt' file of the distribution. The binary installer is recommended for Windows. Zope 3.2 requires Python 2.4.2 to run. You must also have zlib installed on your system. Most Important Changes Since 3.1 - The ZServer has been replaced with the Twisted server. The Twisted server supports all that the ZServer supporting has well has HTTP over SSL natively and SFTP (disabled for now because of error handling problems). Also in the future it brings a better chance of other non-HTTP related protocols from being implemented for Zope3, like SMTP-in and IMAP. ZServer is still supported and will be used if you use the --zserver when you run mkzopeinstance. - Added a test browser. The test browser simulates a real Web browser as much as possible as a Python object. This allows us to write functional tests the same way the site would be experienced by the user. This greatly simplifies functional tests, makes documentation better and even helps analyzing usability. And of course, it can be used in functional doctests. - Changed the way returning large results is handled. The response.write method is no longer supported. Applications can now simply return files to the publisher. - Implemented the password managers proposal. Main idea beside the proposal is a standard way to implement password encoders/checkers, see zope.app.authentication.interfaces.IPasswordManager for details. + Added basic password managers: Plain Text, MD5, SHA1. + Support for password managers added for ZCML principals and principals saved in local PrincipalFolers. + Added bin/zpasswd command line script which helps to create ZCML principals. + Password managers support integrated into bin/mkzopeinstance. + New database generation created for convert local principals to new format. - Implemented the language namespace proposal. Now you can override the browser preferred language through the URL, like this: http://site.org/++lang++ru/path Note: If you want to use a custom IUserPreferredLanguages adapter and the '++lang++' feature together you should use zope.app.publisher.browser.CacheableBrowserLanguages adapter as a base class or at least as example. - Implemented a new object introspector. Instead of just providing information of the object's class, the new introspector focuses on providing information that is specific to the instance, such as directly provided interfaces and data, for example attribute values and annotation values. - Implemented the `devmode` switch for `zope.conf`. When turned on a ZCML feature called `devmode` is provided. Packages can then register functionality based on this feature. In Zope 3 itself, the devmode is used to only load the API doc is devmode; turning off the devmode thus closes a potential security hole and increases the start time by more than a second. - addMenuItem directive supports a `layer` attribute. - Added a re-implementation of i18n message IDs (now simply called ``Message``) that is immutable and thus can be treated like unicode strings with respect to security proxying. This implementation will replace the old one in upcoming versions. - Added "test" message catalog for testing i18n. If you specify ++lang++test in a URL, then all translated strings will be translated to [[domain][message_id], as in "[[zope][Preview]]". Text without the domain marker isn't translated. For a complete list of changes see the 'CHANGES.txt' file.

Uploading file to Zope
by Sune Christiansen 08 Jan '06

08 Jan '06

Hei. I am trying to upload a pdf file to a plone zope server but when I do so I get the following error massage: ValueError Sorry, a site error occurred. Traceback (innermost last): Module ZPublisher.Publish, line 175, in publish_module_standard Module ZPublisher.Publish, line 132, in publish Module Zope.App.startup, line 204, in zpublisher_exception_hook Module ZPublisher.Publish, line 64, in publish Module ZPublisher.HTTPRequest, line 385, in processInputs Module cgi, line 511, in __init__ ValueError: Maximum content length exceeded (Also, an error occurred while attempting to render the standard error message.) The file is 246 KB. When I try to upload a smaller file it works fine, so I presume I have to change some kind of parameter defining the maximum length. Any suggestings where to do that? Thanks, Sune

> Actually, that's not true. Languages such as Perl and Python > were designed to write scripts, not to code entire > applications. Prove it. Prove what the creators and initial shapers of the language intended! There is an argumentative fallacy called "hasty generalization" - surely you know what I'm talking about. This is a baseless claim without warrant or data, and is a generalization tantamount to saying something silly like "Lisp was only created to give Emacs users a way to change their colors." > Python is an exception because it can be > successfully used to code large applications, unlike some > other scripting languages. Have you considered that you are trying to create a rule and find a way for the exception not to prove it false. Has it occurred that you are creating a false dichotomy? You sound as silly as clerics in medieval Europe in denial about retrograde motion of the planets in the night sky - after all, we all know that the Earth is the center of the universe. That analogy is apt because it is the same pattern of logic - try to scapegoat the obvious hole in your theory as an irrelevant outlier, label it, and hope that an inquisition of name-calling destroys it. > So it's best to call Python a > "scripting programming language" because it has this dual > nature. So what really matters is what we call it? I must make a note to remember how much more important this is than how we use it. > All said and done, I prefer to use Java over Python > for large applications Good for you; there are others that share your tastes, but that's all it is: preference. A good coder could create an equally powerful suitably large application in either language in the same amount of time. The only difference is that the Python coder's wrists hurt 75% less from doing 25% of the typing, and the Python coder's peers' eyes hurt 75% less as they can read code quicker. > simply because it's cleaner and has > mechanisms in place that support reusability of components > and extensibility. Huh? You can do pretty much the same designs, patterns, etc in Python. Why does language make a difference here in re-usability. Perhaps you are arguing for single-inheritance as a constraint (which you can self-impose in design in Python). > Also, OO concepts such as abstraction and > inheritance are well defined in Java. And they aren't in python. I think this is just another baseless statement. > Also, both compiled and interpreted languages have their > advantages and disadvantages. The real Java/Python debate is about dynamic strong typing versus static strong typing. Such debates have already been had, ad nauseum, elsewhere. This "interpreted" or "scripting versus programming" angle on a language flamewar is neither new, nor insightful.
