ZSmime 1.1 and revised HOWTO available
by Ng Pheng Siong 21 Mar '01

21 Mar '01

Hello, ZSmime 1.1 is now available. ZSmime enables Zope to generate S/MIME-signed/encrypted messages. ZSmime is useful where Zope accepts confidential information over the web, e.g., credit card numbers, Swiss bank account instructions, etc. Such information can be protected by ZSmime and relayed off-site immediately. This reduces the value of the information carried on-site and in turn reduces the impact of a successful attack against the site. ZSmime adds a new DTML tag "dtml-smime" to Zope. This release improves on error checking. It has been tested with Zope 2.3.0 and Netscape Messenger. The ZSmime HOWTO has also been updated. Get it here: http://www.post1.com/home/ngps As usual, feedback is appreciated. -- Ng Pheng Siong <ngps(a)post1.com> * http://www.post1.com/home/ngps

iuveno AG only Zope company at CeBIT
by Stephan Richter 21 Mar '01

21 Mar '01

Hello everyone, iuveno AG, known from Linuxtag 2000 in Stuttgart and SYSTEMS in Munich, will be at CeBIT in Hall 16, Booth B64 as part of Bayern innovativ. As it is known to us, we are the only exhibitor presenting products based on Zope there. If you just joined the Zope community or if you are already a profound Zope developer, feel free to come by our booth and chat with us. People you may know from the Zope community: Joachim Werner, CEO of iuveno. He presented his "active box system" before and gave a tutorial at Linuxtag. He also offered his booth at SYSTEMS as the Zope meeting point. Me, Stephan Richter ... Well, I don't know what I am known for. Maybe for the crazy idea to have a ZopeCon at Linuxtag? ;-) So, if you are planning to come to CeBIT, feel free to drop by our booth. If you just want to come to meet us and chat with us then that is even better. :-) PS: If you are planning to have a longer Business-related meeting with us, please contact Sven Laue at sven.laue(a)iuveno-net.de or me at srichter(a)cbu.edu to make an appointment.

Localized DateTime classes
by svedovelli 18 Mar '01

18 Mar '01

Hello I have published a patched version of the DateTime class which now adapt itself to the Central European format (dd/mm) instead of the Anglo-american format mm/dd. Moreover the new class now returns day and month names in the localized form. At this very moment I have published two localized versions, Italian and French, but I plan in future to create a more sophisticated version which will try to guess in which country the system is running in order to return the proper translation. Any suggestion is very welcome. If you are interested in localized version for other languages, please, contact me. I will be glad to provide help. You can find the patched class at http://www.zope.org/Members/spinwing/localized_DateTime I hope you will enjoy it Stefano Vedovelli

interview w/Paul Everitt and Ken Manheimer
by Daniel Chudnov 16 Mar '01

16 Mar '01

I was very fortunate to meet Paul and Amos and others at the Digital Creations booth LinuxWorld in NYC, and was blown away by the planning and development going into Zope, especially at the metadata level. We librarians are always looking out for better tools for leveraging the power of standardized metadata systems, and Zope's moving in this direction as fast as anything else going, particularly in the new CMF. Paul and Ken (who both admit to being closet librarians) graciously agreed to an interview for oss4lib to help bring these new metadata developments to light for the community of fellow librarians interested in better metadata management. The interview is available here: http://oss4lib.org/readings/interview-everitt-manheimer-2001-03.php While it is largely geared to our metadata-happy community, perhaps others will find it a worthwhile read as well. Thanks to Paul and Ken's responsiveness and extensive examples it hopefully will help explain where Zope can help take us with content description and management among so many other applications. Regards, -Dan

ANNOUNCE: Zope 2.3.1 beta 2 released
by Brian Lloyd 15 Mar '01

15 Mar '01

Hello all, Zope 2.3.1 beta 2 has been released - you can download it from Zope.org: http://www.zope.org/Products/Zope/2.3.1b2/ Zope 2.3.1b2 contains a number of bug fixes, including the fixes for the issues addressed by the 02/23 and 03/08 hotfixes. It also contains a number of changes to address issues with ZCatalog. New data structures have been introduced to reduce the number of conflict errors caused by object indexing under some types of usage, and to reduce the amount of object database bloat that occurs when indexed objects change frequently. The changes to ZCatalog have been designed so that newly created ZCatalog objects will take advantage of the new data structures. Existing ZCatalog objects will continue to work with the old data structures, but will not gain any of the benefits of the new code. It is possible to upgrade an existing ZCatalog object to use the new data structures by following the How-To at: http://www.zope.org/Members/mcdonc/HowTos/UpgradeToNewCatalog **Users of the Zope source releases should note** that this release contains new C code, as well as a few changes to existing C code. If you are using a source release (or the source diff update), be sure to run 'w_pcgi.py' or 'wo_pcgi.py' as appropriate before starting Zope to ensure that your binaries are rebuilt. For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release: http://www.zope.org/Products/Zope/2.3.1b2/CHANGES.txt http://www.zope.org/Products/Zope/2.3.1b2/HISTORY.txt Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.3.x site.

[ANNOUNCEMENT]: New documentation
by Michel Pelletier 09 Mar '01

09 Mar '01

Hey folks, As I dropped earlier before the conference, I was going to make a number of important announcements. Well, for those of you who could not attend, here they are, as well as some other information that should be of interest to you. First off, as many of you know, New Riders is now publishing The Zope Book. The upshot of this is that the book is now under the Open Publication License (http://opencontent.org/openpub) The book has a new home at SourceForge, and you can go there and check the book out of CVS, add patches, bug reports, and request features. http://sourceforge.net/projects/zope-book/ And now for the *new* news, DC has commited to create a Zope Developer's Guide. This will be the authoritative text on building Zope components. It will cover Interfaces, Components, Persistence, Product Development, Security, Publishing, Debugging, and Testing. Its home is also at SourceForge, and it is also under the OPL. http://sourceforge.net/projects/zope-devel/ And last, but not least, we are writing yet another guide for you, the Zope Administrator's Guide. This guide will cover installation, building, clustering, database troubleshooting and repair, and many other very useful bits of information. Details are the same, SourceForge and OPL. http://sourceforge.net/projects/zope-admin/ As you can see, DC is commiting itself to providing full documentation coverage of all aspects of Zope: using, developing, and administerating. Please visit these projects and tell us what you think. The Zope Book is in its final stages of development, and the dev and admin guides are in their planning stages, so there's still a lot of work to be done. Finally, I'd like to mention that we have decided to start a weekly 'Featured Interface' article to be published in a as yet undetermined online publication, and Zope.org. This weekly article will feature one interface out of Zope, and prose and examples explaining the interface and how it can be used to complete useful projects. These articles will be oriented to be a very useful resource in conjunction with the upcomming dev guide, and will eventually be compiled into an upcomming, comprehensive interface reference for Zope. Well, that's it! (as if that's not enough ;). Stay tuned, and definately give us a hand if you feel the itch to help, we could use it. We are looking for bug-catchers, community editors, feature requests, pointers to existing documentation that can be included, and if you can write according to our guidelines and documentation process, authors. http://www.zope.org/DocProjects/developing Please send any comments or questions to docs(a)digicool.com, or any project specific comments to one of the above SourceForge projects. It was good to meet with many of you at the conference, and I was really pleased to hear lots of positive feedback about our recent documentation efforts. From here, it will only get better, and more fun! -Michel

SECURITY ALERT and Zope hotfix release [2001-03-08]
by Brian Lloyd 09 Mar '01

09 Mar '01

Hello all - An issue has come to our attention (thanks to Randy Kern) that necessitates a Zope hotfix. Hotfix products can be installed to incorporate modifications to Zope at runtime without requiring an immediate installation upgrade. Hotfix products are installed just as you would install any other Zope product. This hotfix (Hotfix_2001-03-08)addresses an important security issue that affects Zope version 2.3.0 and the current 2.3.1 beta 1 release. The issue involves an error in the 'aq_inContextOf' method of objects that support acquisition. A recent change to the access validation machinery made this bug begin to affect security restrictions. The bug, with the change to validation, made it possible to access Zope objects via acquisition that a user would not otherwise have access to. This issue could allow users with enough internal knowledge of Zope to perform actions higher in the object hierarchy than they should be able to. We *highly* recommend that any Zope site running Zope 2.3.0 final or any alpha or beta version of 2.3.0 or 2.3.1 beta 1 have this hotfix product installed to mitigate the issue. Zope 2.3.1 beta 2 will contain a fix for the issue, at which time the hotfix can be removed. Zope versions prior to 2.3.0 are not affected by this issue. - http://www.zope.org/Products/Zope/Hotfix_2001-03-08/README.txt - http://www.zope.org/Products/Zope/Hotfix_2001-03-08/Hotfix_2001-03-08.tgz Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
