Bug-Fix for PackageProduct patch of PatchKit
by Adrian Hungate 04 Sep '01

04 Sep '01

I have just fixed a potentially troublesome bug in PatchKit that makes products that are packaged on a Windows server incompatible with Unix versions of tar. I was (incorrectly) using os.path.join, which inserts '\' in paths, but on Unix this does not create a file in a subdirectory, just a file with a long, strange name. If you have packaged any products using this, you may need to re-package them. (Sorry - Blame me) The corrected PatchKit is available at http://www.zope.org/Members/haqa/PatchKit .

The Zope News for August 31, 2001
by Chris McDonough 31 Aug '01

31 Aug '01

The Zope News for August 31, 2001 by Chris McDonough (chrism(a)zope.com) Also available via http://www.zope.org/Documentation/ZWN/ZWN-2001-08-31 Welcome to the Zope News for August 31, 2001! The top stories this time around include: Zope 2.4.1 beta 1 released, a new ZEO beta is announced, Paul forks off a kid, versioning is hot, Tim Peters gets paid, Zope for Mac OS X, a big fat client, and a Zope-XPath marriage is proposed. And now for something completely different... Front Matter It would have been an excellent several weeks in the Zope community if it hadn't been for the SciFi Channel's re-running of the entire Farscape series on a daily basis (every night, 8pm... well, at least in the US). The actual viewing and discussion of the show has so sapped productivity lately that we're sending Ken Manheimer to forcibly dismantle the transmitter next week. Wish him luck. ;-) Seriously, however, a few people asked last week for me to link the blurb topics in this document's overview section to the respective items in the news text due to the sheer size of this thing. I would have done this, but, well... I didn't. ;-) Sorry! Zope Core Software Development and Releases Zope 2.4.1 beta 1, a minor bugfix release, was released on August 17. It's available from http://www.zope.org/Products/Zope/2.4.1b1 . Jeremy Hylton announces a new ZEO (Zope Enterprise Objects) beta release: "At long last, the fourth and final beta release of ZEO 1.0 is available at http://www.zope.org/Products/ZEO. I expect to release 1.0 final next week." ZEO turns the Zope object system into a distributed architecture, allowing multiple processors, machines, and networks to act as one website. It also basically rules the universe, as far as I'm concerned. Software Development Proposals and Projects Michael Bernstein continues to gain momentum (and lots of comments) on his SecurityJihad proposal, which aims to tighten out-of-the-box Zope security for developers. See http://dev.zope.org/Wikis/DevSite/Proposals/SecurityJihad . Dylan Jay proposes to allow Zope objects to be queried via XPath. See http://dev.zope.org/Wikis/DevSite/Proposals/ZDOMXPath . His PrototypeObjects proposal, though not particularly new, is also very interesting. http://dev.zope.org/Wikis/DevSite/Proposals/PrototypeObjects Shane Hathaway and Jim Fulton's Component Architecture project is turning out to be the genesis of a future "paradigm shift" for Zope development and has received a lot of discussion lately. See http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/RecentChan…. BackTalk is a system based on Zope which allows users to comment on prestructured booklike content through the web. I put BackTalk out a while back on SourceForge, but I haven't really advertised it. I'll do so now. http://sourceforge.net/projects/backtalk/ . This is unspported software, is sparsely documented, and is available only through CVS at the moment. Comments appreciated. A BackTalk demo is available at http://serenade.digicool.com:8187/ZopeBook . Design credits go to Bruce Eckel, Bill Venners, and Kent Hoxsey. Developers wanted! Ken Manheimer produces a comprehensive set of requirements for Zope versioning. This appears to be a step in the direction of encoding a revision-specification scheme into URLs, which looks a little weird at first glance. http://dev.zope.org/Wikis/DevSite/Proposals/VersioningForContentManagement David Shaw makes his second beta binary release of Zope for the Mac OS X platform. It includes Python, his lickable GUI Zope control tool (http://homepage.mac.com/dshaw/ for screenshots), ZEO, and some other assorted goodies. Download it from http://homepage.mac.com/osx/ The Zope Fat Client project (http://sourceforge.net/projects/zfc/) run mostly by our friends at NIP Ltd. is a project aimed at.. well, in their own words, "The Zope Fat Client project aims to explore the space of an interactive and potentially distributed Zope client to compliment Zope's current paradigms."! That's a mouthful. But it looks interesting! Security Notices No security notices since the last News issue. Documentation Development and Releases A CMF FAQ was started on the "dogbowl": http://cmf.zope.org/Members/tseaver/how_tos/faq_announce . I don't think it has been mentioned before in the Zope News, but the documentation folks at Zope Corporation continue to kick out new "Articles" which highlight hands-on use of some of Zope's core technologies. For more info, see http://www.zope.org/Documentation/Articles . The latest article from Michel Pelletier is about using Zope with Amaya, Dreamweaver, and other WYSIWYG HTML tools. Hernan Foffani updates ZopeSHELF for Zope 2.4! The Zope Shelf is a compilation of the Zope Book, the Deveveloper's Guide, the How-Tos, the Articles and an HTML and CSS Ref Guide in Microsoft HTMLHelp format. http://www.orgmf.com.ar/condor/zopestuff.html News Summaries No news summaries since the last News issue. Zope Corporation Goings-On No real news to tell on the "opening" of the Zope CVS. We're still waiting on a wet signature document. The project makes its home, however, at http://dev.zope.org/Wikis/DevSite/Projects/ZopeCVSMigration/FrontPage. Paul Everitt, Zope Corporation principal, is the father of Charles Merlo Everitt, some-odd pounds, some-odd ounces born a few days ago. I'm as usual a little hazy on the details (there was no stork mentioned and I didn't a very good glimpse of him with all the other folks hovering over him and coochy-cooing), but the point is that Paul's a new father. Wish him well via paul(a)zope.com ! Zope Corporation has established a mailing list to specifically discuss issues which arise when integrating Zope and various relational datbases -- zope-db(a)zope.org. Any posting from "how do I?" to "but..." and the ever-favorite "help with ...!" is fair game. If you have an interest in subscribing, please visit http://lists.zope.org/ today, and sign up to the Zope-DB list. EuroZope Goings-On There were no updates on the EuroZope site at http://www.eurozope.org since the last News issue. Zope Sightings I had fun attending the Washington DC Zope Python Users' Group (the DC ZPUG) meeting. There are incriminating pictures. http://www.chrisabraham.com/article.php?sid=109&mode=flat&order=0 . I shepherded a Q&A session without any real topic, after which Andreas Jung (also an employee of Zope Corporation, but desperately pretending not to be) gave a talk about Python as middleware. Michael Roberts of Vivitek writes a piece for IBM developerWorks about how to extend Zope and Python in C. http://www-106.ibm.com/developerworks/library/l-pyzo.html . He appears to have really gotten traction since his last developerWorks article about Zope in April titled "Zope for the Perl/CGI programmer" ( http://www-106.ibm.com/developerworks/library/l-zope.html ). I missed this in last week's issue. Dennis Tenney from Linux Weekly News interviews Guido van Rossum and Jim Fulton. See http://lwn.net/2001/features/oreilly2001/GuidoJimInterview.php3 . Inside, Guido talks about how he likes Zope Corporation, and Jim talks about the component architecture and PHDs. Jon Udell mentions Zope in his byte article on paying forweb services. http://www.byte.com/documents/s=1113/byt20010822s0003/0827_udell.html Tim Peters explains how Zope Corporation calculates his pay rate. http://groups.google.com/groups?hl=en&safe=off&selm=mailman.998686118.5319.… Spoke Technologies' CrankSet is a commercial website-building tool based on Zope. http://www.spoke.net . Maik Roeder's Uzopia has an (older but fascinating) tidbit about how to use the underscore in Python to retrieve the last evaluated expression, as well as some other interesting stuff. You learn something new every day! http://uzopia.editthispage.com/ (scroll down about midway for the underscore hack explanation) Zope.org Meta Matter Due to Zope.org bandwidth and storage abuse by "warez" and MP3 distributors, we were forced to close a few accounts and remove an estimated 2 GB of files, and place some restrictions on File upload sizes. This means that Members can no longer upload files over 500 KB in size. Sorry! Blame society. Webalizer traffic statistics output for the systems that make up www.zope.org is available at http://ns1.zope.org:82/ . The Zope.org site itself has weathered some minor but obvious tweaks lately, mostly having to do with graphics replacements in the header and sidebars. Many thanks to Penney Simpson!

ZEO 1.0b4 released
by Jeremy Hylton 24 Aug '01

24 Aug '01

At long last, the fourth and final beta release of ZEO 1.0 is available at http://www.zope.org/Products/ZEO. I expect to release 1.0 final next week. Zope Enterprise Objects (ZEO) provides the ability for multiple processes to use a single Zope Object Database. ZEO turns the Zope object system into a distributed architecture, allowing multiple processors, machines, and networks to act as one website. The 1.0b4 release fixes all the major bugs reported since 1.0b3. The list of bug fixes is: - Improved robustness of ZEO under load. Many non-fatal socket errors are caught and handled now. Also fix NameError bug that could cause ZEO to fail on Windows. - Reduced the likelihood that a thread.error exception ("release unlocked lock") will be raised if a client disconnects from a storage unexpectedly. - Fixed a bug in undo handling that caused connections to be reset and prevented undos from propagating to all clients. - Fixed a bug that prevented a client from reconnecting to a server if the server restarted. - Fixed start.py so that it prints a message on the console when it fails in addition to using zLOG. - Fleshed out installation instructions and version dependencies. - Fixed bug in non-transactional undo that caused undo to fail and clients to restart.

ImageTag_hotfix - auto thumbnail generation
by marc lindahl 21 Aug '01

21 Aug '01

ImageTag_Hotfix This hotfix makes it so that all Image (and derived) object use PIL to resize when you use the tag method with integer (non-%) height and/or width parameters. This way, stuff like the PhotoAlbum will behave (not give you a page full of full-image thumbnails). This version should be cache aware, it's recommended for big sites to associate these with a RAMcache to cut down on PIL usage- thought it's pretty fast. It also steals the RESPONSE.set_header code from Image so the thumbs are cached on the clients. Since it's a hotfix it's easy to try it and see if it's working for you, and remove it if not. It does not modify any of your images - it generates the thumbs on the fly and only stores them in a RAMcache if you have one set up. Check the README.txt for sage advice on getting PIL to work :) here: http://www.zope.org/Members/bowerymarc/ImageTag_Hotfix
