ZODB 3.2 release candidate 1
by Jeremy Hylton Oct. 2, 2003

Oct. 2, 2003

We are happy to announce that ZODB 3.2 release candidate 1 has been released. You can find it at the usual place: http://www.zope.org/Products/ZODB3.2. This release contains a few bug fixes since the ZODB 3.2b3 release last week. If no major bugs are found in the release candidate, we will make the final release next week with identical code. If there are bugs, we will do another release candidate next week. What is ZODB? It is the Zope Object Database. It provides an object-oriented database for Python that provides a high-degree of transparency. Applications can take advantage of object database features with few, if any, changes to application logic. ZODB includes features such as a pluggable storage interface, rich transaction support, and undo. ZODB 3.2 has a number of new features and improvements over ZODB 3.1: - improve performance and stability of ZEO - new ZEO authentication protocol - new configuration language, ZConfig, for databases, storages, and ZEO servers - many bug fixes - improved documentation - new daemon tools The most recent changes from the NEWS.txt file are included below. -- Jeremy Hylton <http://www.python.org/~jeremy/> What's new in ZODB3 3.2 release candidate 1 =========================================== Release date: 01-Oct-2003 Added a summary to the Doc directory. There are several new documents in the 3.2 release, including "Using zdctl and zdrun to manage server processes" and "Running a ZEO Server HOWTO." Fixed ZEO's protocol negotiation mechanism so that a client ZODB 3.1 can talk to a ZODB 3.2 server. Fixed a memory leak in the ZEO server. The server was leaking a few KB of memory per connection. Fixed a memory leak in the ZODB object cache (cPickleCache). The cache did not release two references to its Connection, causing a large cycle of objects to leak when a database was closed. Fixed a bug in the ZEO code that caused it to leak socket objects on Windows. Specifically, fix the trigger mechanism so that both sockets created for a trigger are closed. Fixed a bug in the ZEO storage server that caused it to leave temp files behind. The CommitLog class contains a temp file, but it was not closing the file. Changed the order of setuid() and setgid() calls in zdrun, so that setgid() is called first. Added a timeout to the ZEO test suite that prevents hangs. The test suite creates ZEO servers with randomly assigned ports. If the port happens to be in use, the test suite would hang because the ZEO client would never stop trying to connect. The fix will cause the test to fail after a minute, but should prevent the test runner from hanging. The logging package was updated to include the latest version of the logging package from Python CVS. Note that this package is only installed for Python 2.2. In later versions of Python, it is available in the Python standard library. The ZEO1 directory was removed from the source distribution. ZEO1 is not supported, and we never intended to include it in the release.

PyCon DC 2004: Call for Proposals
by PyCon Chair Oct. 1, 2003

Oct. 1, 2003

[Please repost to local Python mailing lists.] Want to share your expertise? PyCon DC 2004 is looking for proposals to fill the formal presentation tracks. PyCon DC 2003 had a broad range of presentations, from reports on academic and commercial projects to tutorials and case studies, and we hope to extend that range this year. As long as the presentation is interesting and potentially useful to the Python community, it will be considered for inclusion in the program. The proposal deadline is December 1; the proposal submission system should be up by mid-October. We'll send out another notice with more info when the submission system goes live. Proposals should be 250-1000 words in text (plain or reST) or HTML. You may request either thirty or sixty minutes for your timeslot. Proposals will be accepted or rejected by January 1, 2004. If your proposal is accepted, you may include a companion paper for publication on the PyCon web site. If you don't want to make a formal presentation, there will be a significant amount of Open Space to allow for informal and spur-of-the-moment presentations for which no formal submission is required. There will also be several Lightning Talk sessions (five minutes or less). For more information, see http://www.python.org/pycon/dc2004/cfp.html PyCon is a community-oriented conference targeting developers (both those using Python and those working on the Python project). It gives you opportunities to learn about significant advances in the Python development community, to participate in a programming sprint with some of the leading minds in the Open Source community, and to meet fellow developers from around the world. The organizers work to make the conference affordable and accessible to all. DC 2004 will be held March 24-26, 2004 in Washington, D.C. The keynote speaker is Mitch Kapor of the Open Source Applications Foundation (http://www.osafoundation.org/). There will be a four-day development sprint before the conference. We're looking for volunteers to help run PyCon. If you're interested, subscribe to http://mail.python.org/mailman/listinfo/pycon-organizers Don't miss any PyCon announcements! Subscribe to http://mail.python.org/mailman/listinfo/pycon-announce You can discuss PyCon with other interested people by subscribing to http://mail.python.org/mailman/listinfo/pycon-interest The central resource for PyCon DC 2004 is http://www.python.org/pycon/dc2004/ -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ "It is easier to optimize correct code than to correct optimized code." --Bill Harlan

patch to add support for jabber and spread messages to logging
by g.p.ciceri Oct. 1, 2003

Oct. 1, 2003

Hello all, I've just finished a little patch to logging.handlers to send logging events notification as both jabber and spread messages. It's rather untested, but perhaps it's already useful. You'll find it at http://pyhacks.suddenthinks.com/ Any comment will be appreciated, as usual.
