ANN: Zope News for August 17 Released
by Chris McDonough 17 Aug '01

17 Aug '01

The Zope News for August 17, 2001 by Chris McDonough (chrism(a)zope.com) also available via http://www.zope.org/Documentation/ZWN/ZWN-2001-08-17 Welcome to the Zope News for August 17, 2001! The top stories this time around include: Zope 2.4.0 released, Digital Creations pulls a name change, two security hotfixes released, documentation updates, ZDP alive?, EuroZope eats out, components are on the brain, Zope.org attacked by morons, more on opening up CVS, Zope 2.5 plan published, and the Zope "Weekly" News changes hands. And now for something completely different... What Is Zope? Zope is an open source web application server that can be used for managing website content, building intranets, and creating portals. For more information, see http://www.zope.org Zope is built using the Python programming language. For Python information, see http://www.python.org Front Matter A change of editorship has befallen the Zope News. Zope News readers will sadly no longer be treated to the deadpan editorial stylings of Ethan "Mindlace" Fremen, whose steady hand has guided the ZWN since what seems like the dawn of time. Ethan has retired to the Ukraine to live out the rest of his days as a feudal lord, and in doing so, has passed the editorial baton to me (Chris McDonough). The king is dead, long live the king! As a part of this editorship turnover, the Zope (ahem) "Weekly" News is changing its name to the Zope News in light of and in reverence to its not-so-weekly appearance. It will be produced biweekly from now on, and is meant to be released on the first and third Fridays of every month. If we miss the biweeklies.. well, at least nobody can make fun of the name! The change in editorship means that the content and format of the News is changing slightly to include "almanac" content from Zope.org as well as summations of interesting Zope maillist discussions. Hope you enjoy! Zope Core Development and Releases Zope 2.4.0 was released on July 23. You can download it from http://www.zope.org/Products/Zope/2.4.0/ New Features include: - Zope 2.4 supports (and requires) Python 2.1 - New restricted execution architecture - WebDAV Level 2 locking support - New "WebDAV Access" permission - A new built-in 'Authenticated' role - Product refresh without restart during development - New "Drop-in indexes" support for ZCatalog Read more about the new release at http://www.zope.org/Products/Zope/2.4.0/zope_240_released Zope 2.4.1, a minor bugfix release, is reportedly due in a matter of days. Zope Corp's Zope 2.5 development plan, which showcases new features slated to be added to the next major Zope release, is online. See http://dev.zope.org/Resources/zope_250_plan.html for the whole scoop. One of the important items slated for inclusion into Zope 2.5 is Zope Page Templates. ZPT is a technology which allows HTML designers and programmers to work together to create presentation and logic without stepping on each others' toes. Relatedly, a new release of Zope Page Templates that works with already-existing Zopes, ZPT 1.4, is out. See the Zope Page Templates Wiki for release and download details: http://dev.zope.org/Wikis/DevSite/Projects/ZPT/FrontPage . Other Development Phabric, a project which has as its essential goal the porting of Zope to Jython (the Python language as implemented in Java) has been announced. The project is sponsored by a company named WebElite. See http://www.phabric.org for more information. Brian Lloyd has done a lot of work coming up with a reasonable proposal for better Zope web services. See http://dev.zope.org/Wikis/DevSite/Proposals/WebServicesForZope Michael Bernstein is raising a ruckus on various lists with his SecurityJihad proposal See http://dev.zope.org/Wikis/DevSite/Proposals/SecurityJihad . Jeffrey Shell proposes unification of the tests that ship with the Zope core. http://dev.zope.org/Wikis/DevSite/Proposals/CleanUpAndUnifyCoreUnitTests Toby Dickinson proposes a transactional email capability. http://dev.zope.org/Wikis/DevSite/Proposals/TransactionalEmail Security Notices Two security hotfixes have been released since the last Zope News. It's recommended you check them out and install them if necessary. http://www.zope.org/Products/Zope/Hotfix_2001-07-25/security_alert http://www.zope.org/Products/Zope/Hotfix_2001-08-04/security_alert Documentation Development and Releases Although it was covered in the last Zope News, it bears repeating that the printed version of "The Zope Book" by Michel Pelletier and Amos Latteier became widely available in bookstores not too long ago. This is the dead-tree version of the content available from http://www.zope.org/Members/michel/ZB/ . If you buy it, maybe Michel will be able to afford a laptop on which he can run a better window manager than twm. ;-) The Zope Developer's Guide and Zope Book have been updated to match the features of Zope 2.4. See http://www.zope.org/Documentation/ZDG and http://www.zope.org/Members/Amos/ZopeBook24 . Thanks to Amos Latteier and Michel Pelletier. The Zope Documentation Project (http://zdp.zope.org) seems to have stalled almost entirely. The last update to any of its content appears to have been made in May! Egads. Alestay ontentcay entralcay! News Summaries Erik Enge's zope-dev maillist summary for July was relased. It's available at http://nittin.net/erik/summaries/2001-08-01 . Seb Bacon's CMF Week In Review #6 for the week ending July 27 is available from http://cmf.zope.org/news/weekly/20010727. Digital Creations Goings-On Digital Creations, Inc. (the producer of Zope) has changed it's name to "Zope Corporation". There is a new website at http://www.zope.com accordingly. The name change is intended to ensure that Zope (the application) and its primary financial backer are more closely associated with each other in the marketplace. See http://www.zope.com/News/PressReleases/DC2ZC for more info. A components architecture chat was had with Jim Fulton and Shane Hathaway from DC/ZC with the rest of the Zope community on August 3rd. A log of the chat is available at http://irclogs.espnow.com/zope-logs/show_file.php?logfile=Aug_03_2001.log. For the most part, Shane and Jim explained the content in the Zope Component Architecture wiki (see http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/FrontPage) which really essentially just turns out to be a set of best practices to use when developing Zope applications, as well as a set of enabling technologies. Ken Manheimer continues to plug away at opening up the CVS repository to contibutions external to and unmediated by Zope Corporation. A record of his travails is available at http://dev.zope.org/Wikis/DevSite/Projects/ZopeCVSMigration/CurrentStatus. EuroZope Goings-On This happened a while back (a whole month ago!), but was neglected mention in any prior Zope News. The EuroZope crew (http://www.eurozope.org ) had a barbeque in Berlin. There are pictures. They are mostly incriminating, and they feature about four thousand shots of Noa Harvey, which is fine with me. See http://adequat.c2a.fr/presentation/ZopeBerlin for the pics. Also a great shot of Michel Pelletier somewhere in here. Zope News Sightings A slightly "trollish" article at http://slashdot.org/article.pl?sid=01/08/14/2327248&mode=flat about web services in relation to open source software posted on LinuxToday and Slashdot generated lots of heat within those communities. Lots of (sane) people argued within the respective site talkback threads that "the answer is Zope." A bit of Linux Weekly News coverage at http://lwn.net/2001/features/oreilly2001/ of the latest O'Reilly Open Source conference deals with presentations given by Zope Corp folks. A bad picture of Tres Seaver and a good picture of Jim Fulton are contained within. Because I'm a Zopeaholic, I like to visit the Netcraft website (http://www.netcraft.net) every month to see how many folks are using Zope. Though their numbers don't take into account all the Zope sites behind Apache or other web or proxy servers, it's somewhat interesting all the same. See http://www.netcraft.com/survey/Reports/200107/byserver/Zope/index.html for Zope stats for July. Zope.org Meta Matter A small collection of morons is busy abusing Zope.org's "openness". This group uses Zope.org as a "warez" repository, creating throwaway accounts and storing large files in the various Member areas associated with these accounts. The large files are then downloaded many times by other morons. All of this activity takes up lots of disk space, bandwidth and other system resources. The Zope.org staff is busy fending off the onslaught. And they say open source software doesn't cost money! [;-)] Webalizer traffic statistics output for the systems that make up www.zope.org is available at http://ns1.zope.org:82/ Zope.org Almanac The Zope.org Almanac lists select new or updated content spotted on Zope.org since the last release of the Zope News.

[Ann] copyPropertySheet
by Dieter Maurer 11 Aug '01

11 Aug '01

Zope's support for PropertySheets is very weak. They cannot be renamed or copied. They can be exported but only imported if they are empty. The reason for these restrictions: The property values are not stored in the sheet but in the associated v_self (value self). The persistence mechanism, on with copying, renaming and export is based, cannot find them in the current implementation. copyPropertySheet uses the specific PropertySheet interface to handle property values correctly. You can use it to copy a PropertySheet sheet into a container container and optionally give it a different id. sheet and container can be either strings or objects. Strings are resolved into objects with restrictedTraverse. container defaults to the sheets container. Download at URL:http://www.dieter.handshake.de/pyprojects/zope Dieter

dtml-sendmail and transactions: Request For Comments
by Toby Dickenson 09 Aug '01

09 Aug '01

A new fishbowl proposal http://dev.zope.org/Wikis/DevSite/Proposals/TransactionalEmail Zope's dtml-sendmail tag is not integrated into the transaction system. This leads to two problems: o Duplicate copies of each email will be sent if a request has to be retried due to a conflict error. o Emails can be sent even if a request never completes, due to an error rendering the tail of the page, or a problem detected at transaction commit. Any comments gratefully accepted. Toby Dickenson tdickenson(a)geminidataloggers.com
