[ANN] MailBoxer 3.3 released
by Maik Jablonski 31 Aug '04

31 Aug '04

Hi, I've just released a new version of MailBoxer (3.3). # What is MailBoxer? MailBoxer is a mailinglist-/ newsletter-/ mailarchive-framework for Zope and is easy to use and customize. MailBoxer runs all mailinglists of the German Zope User Group (www.dzug.org) with several hundred subscriptions and mails per day. # Where can I see MailBoxer working? Have a look at the zope(a)zope.org-archives mirrored by MailBoxer: http://www.dzug.org/mailinglisten/zope-org-zope/ # Where can I download MailBoxer? http://mjablonski.zope.de/MailBoxer # What changed in 3.3? - added support for Jens Vagelpohls MaildropHost (http://www.dataflake.org/software/maildrophost) so MailBoxer works transactional (no more doubled mails due to read-/write-zodb-conflicts). Using MaildropHost is the RECOMMENDED setup for MailBoxer from now on!!! Thanks to Jens for a really great product, which should be the default MailHost-Product in Zope! - added a customizable view (mail_approve) with pending requests for moderation. Please use this template instead of the old plain-text messages. If no template is found, MailBoxer falls back to the old plain-texts. I'll drop this fall-back behaviour in one of the next releases. - added a unique id for queued messages, so a accidentially page-reload won't approve / discard a newly arrived mail. - added a unique message-id for each mail which is bulked to the list, so problems under some setups with cross-posts to several lists should be gone. Thanks to Christian Theune and his inital "5-minute-hacked-patch", which needed some improvements. Hope you like it this way, Christian...;) - fixed bug: if the url given to the smtp2zope.py is not found (404) (maybe some typo in the alias-file), the mail is bounced with "user-doesn't-exist" and not(!) queued by the MTA anymore for a next retry. Thanks to Christian Theune for patch! - fixed bug: the mail-bulk-code was protected with a "historical" try-except, which could result in loss of emails when something went wrong while talking to the smtp-server. - fixed bug: the smtp-connection is now closed / reopened after each batch, so MTAs which only accept a limited number of mails per connection won't defer your mails anymore. - fixed bug: under some wired circumstances the Mail in the REQUEST wasn't marshalled as string by Zope, so string-operations were broken on the mail-data. Added a getMailFromRequest()-method which does the string-conversion, so we always have a string. Thanks to Dirk Datzert for tracking this down! - fixed bug: searchMailBoxerArchive() used unrestrictedTraverse for traversing the Catalog. Changed to restrictedTraverse. - some minor refactorings & code-cleanups. Happy mailboxing, Cheers, Maik -- Maik Jablonski Universität Bielefeld - Zentrum für Lehrerbildung http://www.zfl.uni-bielefeld.de/personal/mjablonski/

[Ann] IncrementalSearch 0.1, ManagableIndex 0.10, AdvancedQuery 0.6
by Dieter Maurer 22 Aug '04

22 Aug '04

"IncrementalSearch" is an efficient incremental search engine supporting 'and', 'or' and 'not' queries. Unlike Zope's standard search engine, it determines hits incrementally, one at a time. It interleaves index lookup and thereby prevents the creation of large intermediate result sets and touches (almost) as few index blocks as possible. This can significantly reduce load time. Measurements comparing an incremental PathIndex with a standard Zope PathIndex showed speedups between 0.8 upto 50. Download: <http://www.dieter.handshake.de/pyprojects/zope#IncrementalSearch> "ManagableIndex" is a flexible indexing framework for the construction of efficient indexes tailorable via the Zope Management Interface. It now comes out of the box with Field-, Keyword-, Range-, Path- and WordIndexes. Unlike other index implementation which support pattern matching only for TextIndex, Managable Field-, Keyword- and WordIndexes support both glob as well as regular expression matching provided the indexed values are strings. New in version 0.10: * it now uses "IncrementalSearch" if available * an improved PathIndex with a new "depth" search option. While "level" controls the distance of the search path from the beginning (as with the standard PathIndex), "depth" controls its distance from the end (in a symmetrical way). * Fixes for unicode values Download: <http://www.dieter.handshake.de/pyprojects/zope#ManagableIndex> "AdvancedQuery" is a Zope product aimed to overcome several limitations of ZCatalog's native search function. Like ZCatalog's search, it supports elementary index searches. While ZCatalog can combine such elementary searches only by "and", AdvancedQuery allows them to be combined arbitrary with & (and), | (or) and ~ (not). While ZCatalog supports an efficient sorting via an index on one level, AdvancedQuery supports sorting via any level of (field) indexes. Moreover, it sorts the result incrementally -- only as far as you access your result. This can drastically speed up the time required for sorting. It uses Python's generators for this (and thus requires Python 2.2 or better). New in version 0.6: it now used "IncrementalSearch" if available. Download: <http://www.dieter.handshake.de/pyprojects/zope#AdvancedQuery> IMPORTANT NOTE: I consider to forbid institutions of the European Union (Commission, Council of Ministers, Parliament, ...) to use software developped by me. This is in protest against plans of the Council of Ministers to make logic (general ideas outside of a concrete technical system) and especially software patentable in Europe. Note that with such a restriction, this software will cease to be compatible with the GPL (GNU Public License). This version does not yet have the restriction but a future version may. -- Dieter

Zope X3 3.0.0 beta 3 released
by Stephan Richter 15 Aug '04

15 Aug '04

The Zope 3 development team is proud to announce the third beta release of Zope X3 3.0.0. Zope X3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. The "X" in the name stands for "experimental", since this release does not try to provide any backward-compatibility to Zope 2. Downloads http://zope.org/Products/ZopeX3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt of the distribution. The binary installer is recommended for Windows. Changes since beta 2 - Updated to use ZODB 3.3b2. - Reviewed security and fixed many outstanding open issues. This required some rearranging and writing of security-related code. - Removed several uses of 'removeAllProxies()' as this is considered a bad coding practice. - Added 'zope.security.proxy.removeSecurityProxy()' function to replace 'zope.security.proxy.trustedRemoveSecurityProxy()'. - Implemented rdb:gadflyRoot directive. You are now able to specifically point to a directory that should contain the gadfly databases. - When browsing the source code via the API doc tool's Class Browser, ZCML files are now shown as well. When viewed, a marked up version of the ZCML code is shown with links to other parts of the documentation. - Resolved or otherwise dealt with issues 112, 122, 130, 133, 139, 162, 190, 194, 202, 203, 211, 212, 219, 220, 221, 225, 228, 231, 234, 235, 238, 239, 245, 247, 249, 251, 252, 253, 255. - Fixed various bugs in the API doc tool. - Factory IDs have to be real IDs now, i.e. either a dotted name or a URI. - Cleaned up much of the source code. Now every module should have a module doc string with a title and 'id' tag in it. Goals The API is frozen for X3.0.0. We would like to ask all people to test this release and report any bugs or mis-behaviors! This might be the last beta release! The entire beta period will likely last for about 2 months. During this time we will try to complete the following tasks: - Fix outstanding bugs. - Optimize critical components to speed up the system. - Write and update documentation. - Add and complete translations. - Remove as many XXX comments as possible. Though much progress has been made since the second beta, there are still tasks to be completed! Even if you are not a programmer, you can help! Please send any bug reports and comments to zope3-dev(a)zope.org! Thank you very much in advance for your help! Contributors Jim Fulton, Fred Drake, Dmitry Vasiliev, Philipp von Weitershausen, Stephan Richter, Garrett Smith, Tim Peters. Thanks to everyone!
