[ANN] Zope 2.8.1 final released
by Andreas Jung 11 Aug '05

11 Aug '05

Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.1. You can download Zope 2.8.1 from http://www.zope.org/Products/Zope/2.8.1/ Some new features of Zope 2.8: - ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. - Integration of Zope 3 technologies through Five (see http://codespeak.net/z3/five/) For more information on what is new in this release, see the CHANGES.txt files for the release: http://www.zope.org/Products/Zope/2.8.1/CHANGES.txt See also: http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView Please bring all the bugs you have found to the Zope bugtracker: http://collector.zope.org/Zope":http://collector.zope.org/Zope For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.plope.com/Books/2_7Edition/InstallingZope.stx Please also keep in mind that Zope 2.8.1 requires Python 2.3.5. Zope 2.8.1 is not certified for any Python 2.4.x versions. So using Python 2.4 is neither recommended nor supported and any related questions or problems are likely to be ignored until 2.4 is an officially support Python version for Zope. -- Andreas Jung (andreas at zopyx dot com)

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

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).

SECURITY WARNING: Don't use the Zope 3 sendmail mailer
by Jim Fulton 29 Jul '05

29 Jul '05

There is a feature in Zope 3, called the "sendmail" mailer, which is not enabled by default, for using a shell command to invoke a mailer to send mail. (The name comes from the popular Unix mailer sendmail, which is often invoked as a sub-process.) Invoking a shell from a server program is a potential serious security hole. This feature can be enabled with a ZCML directive like: <mail:queuedService permission="zope.SendMail" queuePath="./queue" mailer="sendmail" /> If you have added a directive like this to your configuration, you should remove it or change it to use the smpt mailer: <mail:queuedService permission="zope.SendMail" queuePath="./queue" mailer="smtp" /> This feature will be removed in future versions of Zope, including Zope 3.1, and 3.0.2 (if there is a 3.0.2). If you gave questions about this, please send them to the Zope 3 users list, zope3-users(a)zope.org. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!
