[Ann] [Zope3 in Zope2] "localevent": Zope3 events in Zope2 applications
by Dieter Maurer 07 Mar '05

07 Mar '05

Events (and event subscriptions) are a major concept for loose integration of independent components. Zope3 supports events and event subscriptions. However, its subscriptions are global. Many (local) services are interested in events generated in a specific subsite. A prominent example are catalogs that catalog objects in a subsite. "localevent" is a Zope2 product. It provides a (persistent and local) local_event_subscription tool (in the sense of CMF tools). Other tools can use it to subscribe for (Zope3) events originating in the subsite rooted in the parent of the local_event_subscription instance.

A second Zope 3 book
by Philipp von Weitershausen 07 Mar '05

07 Mar '05

Hello all, I'm proud to announce that a second book on Zope 3, "Web Component Development with Zope 3", is officially out now. It is the ideal companion to Stephan Richter's expert "Developer Handbook", serving as a general introduction to Zope X3.0 from a beginner and intermediate point of view. The book covers every aspect of X3.0, the latest Zope 3 release. All chapters are accompanied by a common example application. Prior Zope 2 knowledge is not necessary, though useful. The book also provides a full ZCML and zapi reference in the appendix. More information about it, such as a sampler chapter and locations to buy, can be found at the book's offical website, http://worldcookery.com. At this point I'd like to thank everyone who made this book possible, most importantly Springer-Verlag for publishing it, Jan Smith for her invaluable advice and proof-reading, Sidnei da Silva and Fred L. Drake for their technical support and proof-reading, Róman Joost for his contribution to the example application and last but not least Paul Everitt for his advice and for writing the foreword. Best regards, Philipp

ZODB 3.2.6 beta 1 released
by Tim Peters 01 Mar '05

01 Mar '05

I'm pleased to announce the release of ZODB 3.2.6 beta 1. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.2 There are several critical bugfixes in this release, addressing rare problems in two major areas: - Thread and asyncore races while ZEO is attempting to make a connection, leading to connection failure and/or missed messages. - Rare cases in which FileStorage could reuse oids already assigned, leading to distinct objects with the same oid (object identifier). The primary cause was that FileStorage.restore() didn't update the storage's idea of the largest oid in use, regardless of how large an oid was passed to it. The first stage of ZRS recovery, and copyTransactionsFrom(), both rely on the .restore() method, and so both could create database copies that believed no oids had yet been assigned. A secondary cause was that a FileStorage's .index file contains a "maximum oid in the index" record, and the value in this record was believed even when it was incorrect. The primary cause was repaired by simple changes to .restore() and .store(), so that .index files with a bad max-oid record are no longer created. But there may be such databases already in existence, so the secondary cause was addressed by larger changes to ignore the max-oid record in the .index file, extracting the largest oid directly from the index instead (this is basically a BTree mapping oids to file offsets, so finding the largest key is very efficient; the separate max-oid record is really a leftover from earlier times, before a BTree was used here). Note that although ZODB 3.2.6 ignores an .index file's max-oid record, it still writes a max-oid record when it saves an .index file. This is so older ZODB releases can continue to read .index files produced by ZODB 3.2.6. See the news file for details: http://zope.org/Products/ZODB3.2/NEWS ZODB 3.2.6 can be used with Zopes in the 2.7 line, at or after Zope 2.7.3. Note that ZODB 3.2.6 does not support development on Zope 2.8, Zope X3 or Zope 3 (they require the ZODB 3.3 line).

DeadlockDebugger 1.0
by Florent Guillaume 23 Feb '05

23 Feb '05

Debugging a running or deadlocked Zope http://www.zope.org/Members/nuxeo/Products/DeadlockDebugger This product adds a hook so that a deadlocked Zope process can be debugged, by dumping a traceback of all running python processes. The dump is sent to the event log (at the DEBUG level) and returned to the browser (even though the Zope is deadlocked and doesn't answer any other requests!). DeadlockDebugger can of course also be used to debug Zope in non-deadlock situations, when a Zope process is taking a long time and you wish to know what code is being executed. DeadlockDebugger requires the third party 'threadframe' python module, http://www.majid.info/mylos/stories/2004/06/10/threadframe.html Florent -- Florent Guillaume, Nuxeo (Paris, France) CTO, Director of R&D +33 1 40 33 71 59 http://nuxeo.com fg(a)nuxeo.com
