by Adrian Hungate 15 Feb '02

15 Feb '02

I have just released version 1.1.2 of ZCGI. The following is the change-log entry for this release: Fixed bug where POSTing was not working from a DTML call Fixed bug where Query string was not being passed from a DTML call Added the ability to allow environment variables to pass through to the CGI script Fixed bug where data was POSTed even if method was GET Added support for calling script from DTML etc. Syntax: * ripoffheaders (Def 1) - If true, headers/footers are ripped off output * PATH_INFO (Def []) - List containing path elements for PATH_INFO or string containing entire PATH_INFO * method (Def 'GET') - GET or POST (CGI Method) * All other params are passed as form data. This is not yet supported by ZCGIFolder, only ZCGIScripts You can get ZCGI from http://www.zope.org/Members/haqa/ZCGI Please note, this is still a development level product, but I have had some very promising results. If you can spare some time to test ZCGI in your environment, I would love to hear your results, good and bad!

Zope Python User Group News
by Chris Abraham 13 Feb '02

13 Feb '02

Zopistas: ZPugDC <http://www.zpug.org> Mailing List Died and Rose Again! Well, it used to be quite a fine Mailing List. And it shall be again. First things first, though. Python Motivated Me! I was so motivated by last week's Python 10 conference that I got my hands dirty and with Jon and Ethan's help (thanks iMeme for the free hosting of the ZPug) I have the list up and all the old names in there. (Yes, I am giving up being ZPug-lazy for Lent, if you really must know . . .) ZPug.org was never down, but the list, our lifeblood, was. To get straight to the list, check out DC-Gen <http://lists.zpug.org/mailman/listinfo/dc-gen/>, realising that I am in the process of building a franchising operation wherein all the ZPugs, the PiGs, the ZUGs, the Pugs, and the PZigs can have either a for real home or a referral to the official site. Franchising Opportunities If you need a Mailing List for your local Zope User Group, Python User Group, or ZPug? I have one for you. Just ask. Same thing if you need web space. It will be a subweb off the Zpug site, but we'll learn to share the fridge. <chris(a)zdev.com> Next Gen Zpug is a Community Wonderland So, the next step is the ZPug Community CMF. I will be enlisting your help (those who offered) this upcoming week. It was wicked cool seeing all you all who were there for the Python 10 conference. Also, thank you Miss Joya for hosting the last ZPug meeting and Andrew for winning the Gold and speaking at the last meeting as well.

Vancouver Python and Zope User Group
by Andy 12 Feb '02

12 Feb '02

Announcing the first meeting of the Vancouver Python and Zope User Group (VanPyZ). A few of us Python and Zope users in Vancouver thought it would be cool to meet other users and have a general chin wag. ActiveState has kindly lent us the use of the mezzanine for the opening meeting. We'll start off with a video presented by Paul Prescod that was shown at IPC10: "Python, a love story" followed by an informal natter, then maybe a beer. Along the way we'll see if there is enough interest to do this again on a regular basis, what format it should be and all those niggly details. Date: Thursday, Feb 21st Time: 7pm Location: ActiveState, 580 Granville, Vancouver, BC (http://www.activestate.com/Contact/) Hope to see you all then and if you have any further questions give me a yell. -- Andy McKay

[Ann] TamedXMLExport for Steve Spicklemire's ZCVSFolder
by Dieter Maurer 11 Feb '02

11 Feb '02

Steve Spicklemire has implemented ZCVSFolder, a product that provides restricted CVS support for Zope objects. CVS operations are performed via an intermediate working directory inside the file system. ZCVSFolder uses Zope's import/export facility to synchronize the Zope objects with the corresponding files in the file system and normal CVS commands to synchronize working directory and repository. While ZCVSFolder is already very helpful, there are currently two severe restrictions: 1. The XML export format contains lots of ids consecutively assigned. They provide the necessary references in case that the same subobject is referenced twice. However, these ids make merging a nightmare, as already small changes of an object lead to wide spread changes in these artificial ids. 2. The recursive features of ZCVSFolder are enabled only for standard Zope Folders. Other types of ObjectManagers are not supported. Even for Zope Folders, properties assigned to the folders are not CVS maintained. The reason comes from the fact, that Zope Folders are mapped to file system directories and they do not have place to store the properties. The module "CVSSupport" provides a significant improvement towards the first restriction. More information and download at <http://www.dieter.handshake.de/pyprojects/zope> I fear that even the tamed "exportXML" of this module is not yet stable: When you import an object and export it again, the result may be different from the original XML file causing unnatural revisions in CVS. I am working on a stable export facility. Dieter

Belated Book Blurb
by jerry 11 Feb '02

11 Feb '02

(this is a copy, the address got mangled the first time) Greetings Zope Fans, At long last we are officially posting notice that: "The New Zope Book is here!" In mid-December 2001 a book with a ridiculously long title, and author names to match, turned up in the Web section of bookstores here and abroad. Though no known group claimed responsibility at that time, the alleged authors hereby acknowledge paternity. Since our names are on the cover, it seems rather pointless to remain in denial. "Zope: Web Application Development and Content Management" (ISBN # 0735711100) has been released by New Riders, publishers of the hard copy version of "The Zope Book". The authors were convinced that many Zope hopefuls, not unlike ourselves, had wished for supplementary examples beyond those covered in "The Zope Book". We all agreed it would be ideal to have a series of extended explanations of how and why one puts Zope to practical use. So, we went ahead and wrote it. Z:WAD&CM is designed to step the reader through a sequence of progressively more complex "real world" exercises. After a brief overview, the reader is advised to take advantage of the wealth of existing modules by downloading packages and constructing a dynamic, sophisticated web site in short order. Next, the reader is immersed in user and site administration, content management with CMF and Page Templates, indexes and searching via ZCatalog, and external database access using ZopeDAs and ZSQLmethods. Topics covered in the latter chapters will be most relevant to those facing more challenging needs for robust development standards required by mission critical systems. There you will find examples of load balancing and redundancy using ZEO, multi-developer version control with ZCVS, and ZPatterns based application integration techniques. The authors realize that despite the best intentions to present the current "state of the (Zope) art", our book is merely a set of snapshots from scattered quadrants of the rapidly expanding Zope universe. Still, we hope the finished work is useful, helpful, and may even see a second edition one day. Regarding the pace of Zope development, primary author Steve Spicklemire says: "Writing a book about Zope is like making an ice sculpture of rush-hour traffic." Accordingly, errata, updates, and timely tips have already begun to accumulate at the companion web site: http://webdev.zopeonarope.com Our thanks goes out to all the Zope folks around the globe, and at Zope.com. Your dedication and enthusiasm have made Zope an Object Publishing Environment that sets the bar just a bit higher for everything else. Also, many thanks to New Riders for "taking us on", and for jumping into Zope with both feet! Sincerely, Jerry Spicklemire, (also for Steve Spicklemire, Kevin Friedly, and Kim Brand)

RELEASED - StandaloneZODB 1.0 final
by barry＠zope.com 09 Feb '02

09 Feb '02

I'm please to announce the release of StandaloneZODB, the Python object persistency system also known as the Z Object Database. ZODB is the object-oriented database underlying Zope; the StandaloneZODB project's goal is to provide those same facilities to non-Zope related Python applications. Today we are releasing StandaloneZODB 1.0 final. A brief description of the changes since release candidate 1 is outlined below. StandaloneZODB is based on the same code as the ZODB in Zope, albeit on a separate release branch. Its inspiration comes from Andrew Kuchling's StandaloneZODB project on SourceForge. While there are still some differences, the Standalone 1.0 release is the first on the path toward convergence. Subsequent releases should complete the merge of Andrew's and Zope Corporation's packages. The StandaloneZODB release includes the following components: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - Supporting modules such as ExtensionClass - The persistent BTrees modules - ZEO - Experimental Berkeley storages - Some documentation <wink> See the README file for details on building and installing StandaloneZODB. For details on using ZODB, see Andrew's included user guide. StandaloneZODB 1.0 is released under the ZPL 2.0. It should be compatible with all Python versions from Python 2.1 to Python 2.2. It may or may not work with versions earlier than Python 2.1. Download StandaloneZODB-1.0 from: http://www.zope.org/Products/StandaloneZODB and visit the StandaloneZODB Wiki page at: http://www.zope.org/Wikis/ZODB/StandaloneZODB See also: http://www.zope.org/Wikis/ZODB/FrontPage for more information about our long-range ZODB plans. Enjoy, -Barry Barry A. Warsaw Zope Corporation, Pythonlabs barry(a)zope.com -------------------- snip snip -------------------- What's new in StandaloneZODB 1.0 final? Release date: 08-Feb-2002 ======================================= All copyright notices have been updated to reflect the fact that the ZPL 2.0 covers this release. Added a cleanroom PersistentList.py implementation, which multiply inherits from UserDict and Persistent. Some improvements in setup.py and test.py for sites that don't have the Berkeley libraries installed. A new program, zeoup.py was added which simply verifies that a ZEO server is reachable. Also, a new program zeopack.py was added which connects to a ZEO server and packs it.
