Duplicate messages on zope lists
by Ken Manheimer 29 May '00

29 May '00

Though zope.org's network hookup is once again allowing the mail to get through, we're seeing multiple copies of many maillist messages. We hope to track down the cause of this problem soon - in the meanwhile, we apologize for the disruption! If you want to reduce the impact of the duplicates in the meanwhile, you could try setting your list subscriptions to 'digest' mode. (You may want to leave your zope-announce subscription as is, since it's relatively low traffic, and we're going to use it to announce the resolution of the problem.) To set to digest mod, for example, for the zope list, visit: http://www.zope.org/mailman/options/zope/your@subscription.address and set the digest option. (If you don't know your subscription address, visit the respective roster page, eg http://www.zope.org/mailman/roster/zope If you don't know your password, click the "send password" button on your options page to have it delivered to you.) You may still get duplicates of the digests, but at least they'll come less frequently... Ken Manheimer klm(a)digicool.com

PROPOSAL: Online chat with Jim and Paul
by Paul Everitt 27 May '00

27 May '00

Howdy folks. It's clear that we were unclear in communicating the Perl For Zope announcement. What this needs is a little...clarity! I propose an IRC chat on Wednesday with Jim Fulton and me. The topic will be "What Are Methods and How Does Perl Fit In?" I'll announce time and location later, when someone coaches me on just how you do these damn things on IRC. :^) Why are we doing this? First, I think it's crucial that we at Digital Creations work harder to engage the community in the thinking of Zope. (In fact, this is the number one goal of Brian Lloyd, Zope Product Manager). And the great debate over the announcement makes this a perfect time. Second, I'm hoping that this can become a regular event. The Mozilla crowd has done this, with good success I believe. I'm trying to follow their pattern (one hour, logs posted afterwards). Thoughts? --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909 ----------------------------------------- The Open Source Zope application server http://www.zope.org/ -----------------------------------------

LoginManager 0.8.6
by Ty Sarna 26 May '00

26 May '00

A new release of LoginManager is now available on zope.org. The main changes in this release are support for having user folders at multiple levels in the tree, and preliminary Zope 2.2 compatability (though the Generic User Source hasn't been updated for 2.2 yet and likely won't work). See the Changes file for more details. URL: http://www.zope.org/Members/tsarna/LoginManager/LoginManager-0_8_6.tgz/view

ANN: Perl For Zope
by Paul Everitt 24 May '00

24 May '00

Howdy gang. Below is an announcement that we'll start distributing over the next 24 hours. I wanted to let you folks see it first. In summary: Perl Methods. This isn't a press release, which we'll be doing in the run-up to the O'Reilly Open Source conference in July, when the code is closer to being available. ----------- Digital Creations, creators of the Open Source Zope application server, announced today that it is teaming with ActiveState, a leading provider of Internet programming software, to make Perl a scripting language for Zope. Perl is the predominant scripting language for Internet applications and is a key success story for the Open Source software movement. Zope is written in Python, the fastest growing Open Source scripting language. "It is clear that the strength of Zope realizes the future architecture of the Web," says Paul Everitt, CEO of Digital Creations. "This dynamic architecture, and the people working with it, are a fantastic match for scripting languages. Thus it is natural that Digital Creations would team with ActiveState to make Perl a scripting language for Zope." "Zope is a powerful content management system that we use internally," said Dick Hardt, CEO of ActiveState. "By adding the power of Perl to Zope, we will be able to leverage all the existing Perl technology that we have as well as bring the worlds of Python and Perl closer together." Under this agreement, ActiveState will get Python and Perl to run in the same application. More specifically, Perl programmers can code critical pieces of business logic in Zope solutions. "The Perl for Zope project brings the worlds of the two most important open source programming languages together," stated Gisle Aas, Senior Developer, ActiveState. "Python programmers will be able to directly take advantage of the large collection of reusable Perl program modules, like DBI, found on CPAN. Perl programmers will be able to program and customize the Zope web application server using their favorite language." The initial developer release of Perl For Zope will coincide with the O'Reilly Open Source Software Convention in July 2000. For more information on the project, please visit the Perl For Zope project page at http://www.zope.org/Wikis/zope-perl/. Contact Information For Digital Creations, contact Paul Everitt, paul(a)digicool.com, 540.371.6909x102. For ActiveState, contact Lori Pike, lorip(a)activestate.com, 604.713.8433. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909 ----------------------------------------- The Open Source Zope application server http://www.zope.org/ -----------------------------------------

FYI: Zope Weekly News
by Mike Pelletier 23 May '00

23 May '00

G'day, Zope Weekly News is a digest of some of the useful and interesting events which have occurred on the various Zope mailing lists and the Zope.org site. It is published each Wednesday evening. New Products and Announcements * Paul Everitt announces Sybase support in a joint press release. http://lists.zope.org/pipermail/zope/1999-November/013946.html http://www.digicool.com/News/Sybase * "Zen" released ZRadius, a product which allows you to authenticate web users via the Radius authentication protocol. http://www.zope.org/Members/Zen/ZRadius * Anthony Pfrunder announces VisualZope 0.1a. From his web page: Basically, the "goal" of VZ is to provide a SIMPLE visual editing system for graphic designers which works cross-browser and takes advantage of the acquisition and role systems within Zope. What follows is a brief description of the components which make up the final VZ system (probably more accurate than previous posts). http://163.182.196.200/zwiki/VisualZope * Jeff Sheldon has started a weblog of his experiences with Zope. Jeff Sheldon is new to Zope, and is not a professional programmer. His weblog is a valuable resource to those also starting out with Zope. http://weblogs.userland.com/zopeNewbies/stories/storyReader$0 Updates * Zope 2.1.0 beta 2 has been released. This release includes fixes for issues found in beta 1, an updated load_site.py script and Martijn Pieters' patches to implement try/except/else and try/finally in DTML. Unless something major comes up, this will be the final beta before 2.1.0 final. http://www.zope.org/Products/Zope/2.1.0b2/ * "4am" has submitted an update to his PythonMethod product. It allows methods, written in Python, to be created via the Zope web management interface. http://www.zope.org/Members/4am/PythonMethod * "Drew" contributed an update to his Photo product. It generates thumbnail views of images at the user's preferred size. Requires PIL. http://www.zope.org/Members/Drew/Photo * Itamar Shtull-Trauring announced ZCache v0.2. ZCache is a Python Product which allows you to cache expensive methods, taking strain off your server. It also generates 'Last-Modified' headers, aiding browser and proxy caches. http://lists.zope.org/pipermail/zope/1999-November/014115.html http://www.zope.org/Members/itamar/ZCache Zope.org items * "Zen" submitted a tip he picked up from Michel Pelletier. He explains how volatile attributes work, and how to populate them when your object is loaded from the database. Volatile attributes are attributes which do not get written to the database, and are good for data which changes frequently. http://www.zope.org/Members/Zen/tips/VolatileAttributes * "AlexR" submitted a How-To detailing the use of the DTML entity syntax. "DTML entities" are chunks of DTML which look like this: "&dtml-title_or_id;" http://www.zope.org/Members/AlexR/EntitySyntax Notable Discussions * DTML is a HUGE topic this week. Discussions spill across several lists. A very good job is done of identifying DTML's weak points. Many hold that the difficulty in using DTML comes from it's roots as a reporting language-- it isn't supposed to be used for logic. The problem is, there isn't yet an easy replacement for DTML as a programming language. Python Methods are cited as an excellent start on providing a means of moving logic out of DTML. Christopher Petrilli mentions that DC is looking at grooming Python Methods for inclusion in Zope. Others feel that reporting vs. programming is a forced distinction, and that it is awkward to have to use two different solutions. The claim that generating HTML is actually a rather complex task, and the powerful but ugly features of DTML are a necessary evil. DTML is compared to Perl! <gasp!> Otherwise, lots of very useful tips for using DTML are revealed. An excellent read for DTML beginners and wizards alike. http://lists.zope.org/pipermail/zope/1999-November/013710.html http://lists.zope.org/pipermail/zope-dev/1999-November/002088.html http://lists.zope.org/pipermail/zope-dev/1999-November/002102.html * Darcy Clark alerts the list of Jon Udell's latest article mentioning Zope. Jon's article discusses the ease of using Zope with Windows databases, the pain of using it with Unix databases, cheers ODBC, and jeers lack of a similar magic bullet for Unix. The thread then continues to discuss the relative merits of various free databases and using them with Zope. http://www.byte.com/column/BYT19991104S0001 http://lists.zope.org/pipermail/zope/1999-November/013711.html Also, Karl Fast does an excellent job of summarising the thread, generating more sage comments. http://lists.zope.org/pipermail/zope/1999-November/013762.html http://lists.zope.org/pipermail/zope/1999-November/013812.html http://lists.zope.org/pipermail/zope/1999-November/013813.html http://lists.zope.org/pipermail/zope/1999-November/013840.html * Francois-Regis CHALAOUX posed a question about using Zope with virtual hosting. Several useful responses were generated. http://lists.zope.org/pipermail/zope/1999-November/013678.html http://lists.zope.org/pipermail/zope/1999-November/013688.html * Ben Galbraith submitted a comparison of Zope and Cold Fusion and solicited comments. Some of the usual suspects offer theirs. http://lists.zope.org/pipermail/zope/1999-November/013730.html * Otto Hammersmith started a thread about Zope and security. In it, he speaks of some of the security pitfalls that unsuspecting Zope users could experience. Brian Lloyd submits some solutions. http://lists.zope.org/pipermail/zope/1999-November/013779.html * Paul Everitt wrote in to remind us that there is a zope-dev(a)zope.org list for technical discussions. A brisk discussion developed to debate what constituted a technical discussion. http://lists.zope.org/pipermail/zope/1999-November/013796.html * Theodore Patrick launched a lengthy thread with questions about the effect of threading in Zope. A number of folks from Digital Creations provide answers. The discussion moves on with high volume and content to the topics of benchmarking and performance tuning Zope. http://lists.zope.org/pipermail/zope/1999-November/013808.html * Farzad Farid revives the uncacheable image thread. Because Acquisition can lead to different URLs being generated for images when viewed from different locations, it makes caching difficult and can generate excessive traffic. Others offer advice to solve this problem. http://lists.zope.org/pipermail/zope/1999-November/014021.html * David Harrison asks zope-dev how to return an image generated on-the-fly by an External Method. Answers found. http://lists.zope.org/pipermail/zope-dev/1999-November/002107.html Mike Pelletier
