ZODB 3.4.1 final released
by Tim Peters 10 Aug '05

10 Aug '05

I'm pleased to announce the release of ZODB 3.4.1 final. This corresponds to the ZODB that will ship in Zope 2.8.1. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.4 Note that there are two Windows installers, for Python 2.3 (2.3.5 is recommended) and Python 2.4 (2.4.1 is recommended). There have been many bugfixes in various areas since ZODB 3.4. In addition, optional ZEO client cache tracing was badly broken with the introduction of multiversion concurrency control (MVCC) in ZODB 3.3, and ZODB 3.4.1 is the first attempt to repair that. See the news file for details: http://zope.org/Products/ZODB3.4/NEWS.html Note that ZODB 3.4.1 does not support any version of Zope 2.6 or 2.7. Current Zope 2.8 development uses ZODB 3.4.1, and current Zope3 development uses a ZODB 3.5 prerelease. The ZODB 3.3 line is officially retired (3.3.1 final was the last release in the 3.3 line).

Zwiki 0.44 released
by Simon Michael 03 Aug '05

03 Aug '05

Zwiki is a free wiki engine for Zope, for creating both plain zope and CMF/Plone wikis. You can find out all about it at http://zwiki.org . Nothing earthshaking this month.. unless you count the retirement of the venerable full/simple/minimal ! Summary Drop full/simple/minimal and simplify the standard skin, more robust wiki contents. Upgrade notes Customized skins which use the old wikipage_macros template will stop working with this release, as discussed in the 0.42 upgrade notes. If this affects you, you'll need to make the changes described there now. Changes Page hierarchy * clarify updateWikiOutline and call it on every page view to avoid out of date contents and hopefully avoid the need to call it manually General - skins * drop full/simple/minimal modes from the standard skin. (cf http://zwiki.org/UserDiscussion#msg20050726150738-0700@zwiki.org) * drop backwards compatibility support for pre-0.42 wikipage_macros * drop the background colour in top and bottom bars * wikipage template cleanups * rewrote and redocumented setskin, fixed permission declaration not sure I accomplished much. * (commented out) if a "background.jpg" object is present, use it as the body background image (for the main page view only) Best, --Simon

Fredericksburg, VA ZPUG August 10: .Net, functional testing
by Gary Poster 02 Aug '05

02 Aug '05

Please join us August 10, 7:30-9:00 PM, for the third meeting of the Fredericksburg, VA Zope and Python User Group ("ZPUG"). This meeting has four features of note. - Brian Lloyd, the author of Python for .Net (http://www.zope.org/ Members/Brian/PythonNet/) and the Zope Corporation VP of Engineering, will discuss his .Net platform and give a brief .Net overview. - Benji York, Zope Corp Senior Software Engineer, will discuss current functional testing practices on Zope 3, including using Selenium on Zope 3, using demo storage for functional testing, and using his own compelling new functional test package. Note that the majority of this discussion has strong applicability to automated testing of all web frameworks and applications. - We will serve the now-usual geek-chic fruit, cheese, and soft drinks. - Fred Drake, Zope Corp Senior Software Engineer, Python core developer, Python documentation maintainer and editor, and co-author of the O'Reilly book Python & XML will give two of his books (http:// www.amazon.com/exec/obidos/tg/detail/-/0596001282/) to new attendees. Upon pressure, he admitted that he would be willing to autograph them if bribed with fruit, cheese, and soft drinks. Note that we are eager to have non-Zope-Corporation employees give presentations. :-) We had three new attendees last meeting, for a total of ten. Please come and bring friends! More information http://www.zope.org/Members/poster/ fxbgzpug_announce_3 and below. Hope to see you there!

Zope 3.1.0c1 released!
by Stephan Richter 02 Aug '05

02 Aug '05

The Zope 3 development team is proud to announce Zope 3.1.0 candidate 1. 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 in our opinion that Zope 3.1 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. Please test this release carefully and send us any feedback! In particular, we have tried very hard to keep backward-compatibility with the previous X3 3.0 release, so please let us know if the new release breaks your code. 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 3.1 requires Python 2.3.5 or 2.4.1 to run. You must also have zlib installed on your system. Important Changes Since 3.1.0b1 All of the outstanding issues in the to-do list were completed, which included many bugfixes and the removal of all outstanding XXX comments. There was also a lot of work done in fixing many places that were not translatable. Most Important Changes Since 3.0 - New Pluggable Authentication Utility (PAU), which is similar in philosophy to the Zope 2 PAS. The following features are available in the in the basic PAU facility: + Credentials Plugins: Basic HTTP Auth, Session + Authenticator Plugins: Principal Folder, Group Folder For a detailed description of the pluggable authentication utility, see 'zope/app/authentication/README.txt'. - Major simplifications to the component architecture: + Removal of the concept of a service. All outstanding services were converted to utilities: Error Reporting, FSSync, Authentication. + Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar. + Local registrations can now only have two states: active and inactive. This simplified the code so much, that 'zope.app.utility', 'zope.app.registration' and 'zope.app.site' were all merged into 'zope.app.component'. + Implemented menus as utilities. The API also supports sub-menus now. + Implemented views as adapters. Skins and layers are now simply interfaces that the request provides. - Added an integer-id facility for assigning integer identifiers to objects. - Added basic catalog and index frameworks. - Added "sources", which are like vocabularies except that they support very large collections of values that must be searched, rather than browsed. - Created a new granting UI that allows advanced searching of principal sources. - Implemented a generic user preferences systsem that was designed to be easily used in TALES expressions and via Python code. Preferences can be edited via 'http://localhost:8080/++preferences++/'. A demo of the preferences can be found at:: http://svn.zope.org/Zope3/trunk/src/zope/app/demo/skinpref/ - ZCML now supports conditional directives using the 'zcml:condition' attribute. The condition is of the form "verb argument". Two verbs, 'have feature' and 'installed module' are currently implemented. Features can be declared via the 'meta:provides' directive. - Improved API doctool: Code Browser now shows interfaces, text files and ZCML files; the new Book Module compiles all available doctext files into an organized book; the new Type Module lets you browser all interface types and discover interfaces that provide types; views are shown in the interface details screen; views and adapters are categorized into specific, extended and generic; user preferences allow you to customize certain views; 3rd party modules can now be added to the Code Browser. - Improved I18n-based number and datetime formatting by integrating 'pytz' for timezone support, implementing all missing format characters, and reinterpreting the ICU documentation to correctly parse patterns. - Added '++debug++' traversal adapter that allows you to turn on debugging flags in 'request.debug'. Currently the following flags are defined: source, tal, errors. - Improved logout support. - Added the HTTP request recorder, which lets you inspect raw HTTP requests and responses. It can be used to create functional doctests without requiring third-party tools such as TCPWatch. - Developed a generic 'browser:form' directive. It is pretty much the same as the 'browser:editform' directive, except that the data is not stored on some context or adapted context but sent as a dictionary to special method (by default). For a complete list of changes see the 'CHANGES.txt' file.
