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

www.zope.org host was off the net for 10 hours, is back
by Ken Manheimer 13 Apr '00

13 Apr '00

As several people have noticed, www.zope.org is back. The problem was some trivial hardware mishandling - an insufficiently seated ethernet cable. Of course, it's quite frustrating for *all* of us when the site is unavailable, and our service provider is properly contrite. We're sorry about the disruption - we don't expect it's going to happen again... Ken Manheimer klm(a)digicool.com

Zope News, Articles Welcomed
by Kevin Reichard 13 Apr '00

13 Apr '00

LinuxProgramming.com is now under the management of internet.com, home to several Linux sites (including Linux Today, Linux Planet, and LinuxStart). We're on the lookout for anything of interest to Linux and BSD programmers, and obviously Zope would fall under that category. Please share your stories of Zope: success stories, product announcements, and tutorials. We don't expect you to work for free, so in-depth tutorials will be rewarded with $$. We're working to bring Zope and other open-source tools the wider exposure they deserve, and we appreciate your help. Questions, comments, or idea can be sent to me at kreichard(a)internet.com. --Kevin Reichard Managing Editor, Linux/Open Source Channel internet.com

Local File System bug fix: v0.9.3
by Jonothan Farr 11 Apr '00

11 Apr '00

http://www.zope.org/Members/jfarr/Products/LocalFS This mainly fixes problems with the tree view. OK, so I slipped in a user-requested 'feature' there at the end. I'm just excited that people are actually starting to create their own custom views. - Fixed a bug in __getitem__ that broke the mapping protocol, i.e. localfs['subobject']. - Fixed a problem with tree tag items from separate localfs instances affecting each other's state. - Prevented exceptions in localfs tree rendering from crashing the management interface. - Added 'Display in Tree View' option to disable displaying LocalFS objects in the management tree. - Added LocalFile properties display_size and display_mtime which return formatted properties. The size and mtime attributes now return an integer and a DateTime object, respectively. This should make the LocalFile object more useful for creating custom directory views. --jfarr

Unicode strings in ZPublisher
by Toby Dickenson 10 Apr '00

10 Apr '00

Ive uploaded an updated version of my patch to support... * Unicode strings in ZPublisher; unicode fields in forms * Unicode strings as object properties * Unicode strings that work well with dtml http://www.zope.org/Members/htrd/wstring I've been waiting to release this version for a while (waiting for zope 2.1.6, which fixed some relevent bugs), so it's reasonably stable. However I wouldn't use it for anything important before Python 1.6, when I will switch over to the built-in unicode type. I would be grateful for any feeback, Toby Dickenson tdickenson(a)geminidataloggers.com
