06 Sep '03

Munkware, a transactional and persistent queueing mechanism, is proud to announce version 0.2 for public consumption. Bug fixes/enhancements include: - Bug-fix - re-instantiation of a full queue was throwing an exception. This is fixed now. - Re-added support for the un_*() syntax in addition to *_rollback() - Added support for passing in a callback class. Usefulness of such a feature includes easy queue prioritization, queue filtering, etc. There are a couple of example scripts in the example directory of the download. The Sourceforge Project page is located at http://sourceforge.net/projects/munkware/ and the project home page is located at http://munkware.sourceforge.net/ Future plans for Munkware include: - Better documentation with diagrams of state traversal - currently in progress. - Auto-commit functionality - planned for version 0.3 - Transactional and persistent queueing server with a Web Services interface If you have any suggestions, please feel free to email them to me.

ANN: dnspython 1.2.0b1
by Bob Halley 06 Sep '03

06 Sep '03

dnspython 1.2.0b1 has been released. Here's the README: dnspython INTRODUCTION dnspython is a DNS toolkit for Python. It supports almost all record types. It can be used for queries, zone transfers, and dynamic updates. It supports TSIG authenticated messages and EDNS0. dnspython provides both high and low level access to DNS. The high level classes perform queries for data of a given name, type, and class, and return an answer set. The low level classes allow direct manipulation of DNS zones, messages, names, and records. To see a few of the ways dnspython can be used, look in the examples/ directory. dnspython originated at Nominum where it was developed to facilitate the testing of DNS software. Nominum has generously allowed it to be open sourced under a BSD-style license, and helps support its future development by continuing to employ the author :). ABOUT THIS RELEASE This is dnspython 1.2.0b1. New since 1.1.0: Timeout support has been overhauled. It now works on Python 2.2 as well as 2.3, and the total time spent processing a query is now much more controllable before since the timeout is now on the whole query instead of just on individual network calls. The master file reader now gives the filename and line number of the offending input when a syntax error occurs. $INCLUDE is now supported in DNS master files. Processing of $INCLUDE can also be disabled if desired. BIND 8 style TTLs, e.g. "1w2d3h4m5s", are accepted when reading a master file, but will never be emitted. Basic zone sanity checks are made after a zone is loaded. Specifically, the zone must have SOA and NS rdatasets at its origin. This release fixes all known bugs. See the ChangeLog file for more detailed information on changes since the prior release. REQUIREMENTS Python 2.2 or later. INSTALLATION To build and install dnspython, type python setup.py install HOME PAGE For the latest in releases, documentation, and information, visit the dnspython home page at http://www.dnspython.org/ DOCUMENTATION Documentation is sparse at the moment. Use pydoc, or read the HTML documentation at the dnspython home page, or download the HTML documentation. BUG REPORTS Bug reports may be sent to bugs(a)dnspython.org MAILING LISTS A number of mailing lists are available. Visit the dnspython home page to subscribe or unsubscribe.

Retic EAI Server 0.5 Released - 3 new components
by alexander.dejanovski 05 Sep '03

05 Sep '03

I've released a new version of Retic with new components : - SOAPSource - xmlBlasterSink - XindiceSink (apache foundation XML Database) Other changes are : - Bug fixes in SQLTreeSource (Major one preventing from closing some tags correctly) - Bug fix in SQLSource : fetchall() method was called without all the required arguments (used when msgSize = 0) - Modified fileSink : Now choice is given between appending and overwriting output file - Many improvements on exception handling (now written to loggers with ERROR level) - The designer is now bundled with retic and not anymore alone (works on win32 only). It is available on sourceforge : http://sourceforge.net/projects/retic Feedback would be widely appreciated : alexander.dejanovski(a)laposte.net ============================================================= WHAT IS RETIC ? Retic is an EAI Server. The aim is to permit applications to communicate, even if they don't speak the same language (which means transport protocols as well as data structures). This is done by building adaptors. An adaptor is composed of : - One source - Several pipes (process data transformations) - Several sinks (destination of data) - Several loggers (using the logging module of python 2.3) ============================================================= Have fun !!!

mail is working again
by Barry Warsaw 04 Sep '03

04 Sep '03

I believe that the mail system for python.org and zope.org is now working again. We had several problems related to our Exim installation, running out of disk space, and our spam/virus defenses. Please note that it is possible that some legitimate messages got lost. It may take a while for all the Exim and Mailman queues to get cleared out, so please do not resend your message right away. But if your post does not reach the intended mailing list or python.org recipient within a few days, you may need to resend it. Huge thanks to Jeremy Hylton, Andrew Kuchling, and Skip Montanaro for helping me get the system up and running again. -Barry

ANNOUNCE: MojoView 1.0
by Jamey Cribbs 04 Sep '03

04 Sep '03

MojoView 1.0 is now available at: http://www.netpromi.com/files/MojoView-1.0.zip What is MojoView? MojoView is a Python package that assists you in building simple gui database applications using PyGTK2. It consists of a set of classes that you can subclass in your application. Each class is either a dialog or a widget that should be placed inside a dialog, along with supporting code that handles a lot of the mundane details inherant in most gui database apps. I think that this package will mostly help those new to or unfamiliar with developing PyGTK2 applications. Experienced PyGTK programmers will have probably already developed their own libraries providing similar or better functionality. To find out more about MojoView, go to: http://www.netpromi.com/mojoview.html

ANNOUNCE: KirbyBase 1.5
by Jamey Cribbs 04 Sep '03

04 Sep '03

KirbyBase 1.5 is now available at: http://www.netpromi.com/files/KirbyBase-1.5.zip What is KirbyBase? KirbyBase is a simple, pure-Python, plain-text, flat-file database management system that can be used either embedded in your application or in a client/server, multi-user mode. To find out more about KirbyBase, go to: http://www.netpromi.com/kirbybase.html Changes: Well after reading some posts on comp.lang.python about how slow eval can be, I set about eliminating eval from KirbyBase. It resulted in uglier code, but increased performance, enough of a performance increase that I figured I would go ahead and release a new version. Specifically, the changes are: Changed the way queries are handled internally. Instead of doing an eval to do numeric and datetime comparisons, I changed it to do the actual comparison itself. This resulted in a 40% speed increase on large queries that do comparison expressions. Changed how data is passed between the server and the client in client/server mode. I now use cPickle instead of repr and eval. This resulted in an approximately 40% speed increase in client/server operations. An anecdotal example, doing a date range select query against a 78,000 record table returning 23,800 records in the result set. Version 1.4: 13 seconds Version 1.5: 8 seconds Who says Python isn't fast? :)
