Sydney Python Group Meeting This Thursday 27 July
by hex-dump 24 Jul '06

24 Jul '06

Hi Everyone, The Sydney Python group is having its first meeting for the year on Thursday July 27. Usual time and new place: Thursday, July 27, 2006 (6:30 PM - 8:30 PM) The "new" University of Sydney School of IT Building. Thanks to Bob Kummerfeld for arranging the venue. The venue is approx 1 km from both Central and Redfern stations. Use the entrance from the University side, not the Cleveland St side. If you come from City Rd, enter the Seymour Centre forecourt and follow the curve of the new building down to the foyer entrance. http://www.cs.usyd.edu.au/~dasymond/index.cgi?p=Map Talks: Graham Dumpeton on what is coming in the next major version of mod_python (3.3). This version of mod_python should represent a significant improvement over previous versions in certain areas with ramifications on stability. New features have also been added which make mod_python a bit more flexible than it is now and more useable in the way that Apache modules should be able to be used. Result is that mod_python can truly be used for more than just a jumping off point for stuff like WSGI and all those Python web frameworks that keep popping up every day. Mark Rees on his experiences in using IronPython with .NET and Mono. The talks will be 15-20 minutes in length with plenty of time for questions. See you there. Mark

cx_OracleDBATools 2.2
by Anthony Tuininga 24 Jul '06

24 Jul '06

What is cx_OracleDBATools? cx_OracleDBATools is a set of Python scripts that handle Oracle DBA tasks in a cross platform manner. These scripts are intended to work the same way on all platforms and hide the complexities involved in managing Oracle databases, especially on Windows. Binaries are provided for those who do not have a Python installation. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Added option --replace-existing to CloneDB in order to support issuing one command to replace an existing database with a copy of another one. 2) Always set the enviroment, even when connecting directly using cx_Oracle, as otherwise the wrong SID could be set and the wrong action take place. 3) Do not prompt for the value for ORACLE_HOME if the --no-prompts option has been invoked. 4) Increase the size of the template system tablespace for Oracle 10g as it was too small. 5) On Windows, wait until the service is actually started or stopped before continuing.

cx_OracleTools 7.4
by Anthony Tuininga 24 Jul '06

24 Jul '06

What is cx_OracleDBATools? cx_OracleTools is a set of Python scripts that handle Oracle database development tasks in a cross platform manner and improve (in my opinion) on the tools that are available by default in an Oracle client installation. Those who use cx_Oracle (a Python interface driver for Oracle compatible with the DB API) may also be interested in this project, if only as examples. Binaries are provided for those who do not have a Python installation. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Use cx_Logging to output messages rather than write directly to stderr. 2) Added support for describing comments on tables and columns. 3) Improved output when an exception occurs. 4) cx_Oracle 4.2 is now required. 5) Replace use of executemanyprepared() with executemany() and bind arrays instead of dictionaries which actually improves performance by about 20-25% in some cases. 6) Moved code from module cx_DumpData in project cx_PyOracleLib into DumpData. 7) Provide more meaningful message when source or target directory is missing in GeneratePatch as requested by Micah Friesen. 8) Ignore invalid objects of type "UNDEFINED" when describing objects. 9) Export the roles before the users as the reason the roles are included is because they are administered by the users and the grants will by definition fail. 10) In ExportObjects, create the directory before any exporting actually takes place in order to handle the situation when no objects are exported as requested by Micah Friesen. 11) Eliminated identical grants made by different users when describing objects. 12) Add phrase "(n% of file)" to the reporting message of ImportData when possible as requested by Don Reid. 13) Display something more reasonable when compiling statements that modify constraints.

Toronto Python User's Group this Tuesday, 6:30PM at Linux Caffe (note time change!)
by Mike C. Fletcher 23 Jul '06

23 Jul '06

We're going to try meeting 1/2 hour earlier this month to be more considerate to our hosts, Linux Caffe (who stay open late just for us on the fourth Tuesday of the month). I realise many people won't be able to get down to the Caffe by 6:30, so the first half hour we'll use for socialisation, organisation, picking up coffee and pastries, and generally getting to know one another. We'll start the more "formal" part of the gathering at 7:00. As is usual, we'll go out afterward for beer (or whatever your poison, (cheesecake being a popular second)) for further socialisation and camaraderie. The topic for this week is the SQLObject Object-relational Mapper. This is one of the more popular ORMs for Python which provides a truly OO view of your RDBMS objects which attempts to automate all of your SQL code generation so that you deal largely (only) with Python objects with natural-feeling APIs. We can look at the basic usage patterns, some of the cooler features (such as automated inheritance), and discuss some of the gotchas that show up when using the package. SQLObject is one of the core default packages of the TurboGears web framework, and as such it's probably something you want to learn about, even if you choose another ORM for your projects. Linux Caffe is located at the corner of Grace and Harbord, one block south of Christie subway station. http://www.linuxcaffe.ca It's got a trendy geek-positive atmosphere, great coffee and wifi or hard-line network links. Have fun all, Mike -- ________________________________________________ Mike C. Fletcher Designer, VR Plumber, Coder http://www.vrplumber.com http://blog.vrplumber.com

ANNOUNCE: Optik 1.5.3
by Greg Ward 23 Jul '06

23 Jul '06

Optik 1.5.3 =========== Optik is a powerful, flexible, extensible, easy-to-use command-line parsing library for Python. Using Optik, you can add intelligent, sophisticated handling of command-line options to your scripts with very little overhead. I have released Optik 1.5.3 mainly to ensure that Python 2.5 includes a version of optparse that is derived from a known release of Optik. Sharp-eyed readers will note that I didn't announce 1.5.2 -- that's because I released it prematurely, and then noticed a change to Lib/test/test_optparse.py in the Python source tree that I had to port to Optik. Oops. You can get Optik 1.5.3 from http://sourceforge.net/projects/optik Or you can just wait for Python 2.5rc1, which will include Optik 1.5.3 as optparse. Anyways, here are the changes since the last proper release (1.5.1): 1.5.3 (23 Jul 2006) ------------------- * Port r47026 from Python svn repository: fix unit test so it doesn't screw up other tests in the Python test suite. 1.5.2 (22 Jul 2006) ------------------- * Minor documentation tweaks. * SF bug #1498146: handle Unicode help strings (affects option help, description, and epilog). -- Greg Ward <gward(a)python.net> http://www.gerg.ca/ God is omnipotent, omniscient, and omnibenevolent ---it says so right here on the label.

Ophelia 0.1
by Thomas Lotze 22 Jul '06

22 Jul '06

The first release of Ophelia, 0.1, has just been tagged. From README.txt: ========================================================================= Ophelia creates XHTML pages from templates written in TAL, the Zope Template Attribute Language. It is designed to reduce code repetition to zero. At present, Ophelia contains a request handler for the Apache2 web server. Static content -------------- Consider Ophelia as SSI on drugs. It's not fundamentally different, just a lot friendlier and more capable. Use Ophelia for sites where you basically write your HTML yourself, except that you need write the recurring stuff only once. Reducing repetition to zero comes at a price: your site must follow a pattern for Ophelia to combine your templates the right way. Consider your site's layout to be hierarchical: there's a common look to all your pages, sections have certain characteristics, and each page has unique content. It's crucial to Ophelia that this hierarchy reflects in the file system organization of your documents; how templates are nested is deduced from their places in the hierarchy of directories. Dynamic content --------------- Ophelia makes the Python language available for including dynamic content. Each template file may include a Python script. Python scripts and templates contributing to a page share a common set of variables to modify and use. Ophelia's content model is very simple and works best if each content object you publish is its own view: the page it is represented on. If you get content from external resources anyway (e.g. a database or a version control repository), it's still OK to use Ophelia even with multiple views per content object as long as an object's views doesn't depend on the object's type or even the object itself. Trying to use Ophelia on a more complex site will lead to an ugly entanglement of logic and presentation. Don't use Ophelia for sites that are actually web interfaces to applications, content management systems and the like. ========================================================================= To use Ophelia, you need - Apache2 - Python 2.3 or better - mod_python 3.1 or better - the zope package from Zope3 Ophelia is released under the Zope Public License, version 2.1. You can access the source code repository at <https://svn.thomas-lotze.de/repos/public/Ophelia/>, browse it using ViewCVS at <http://svn.thomas-lotze.de/svn-public/Ophelia/>, and download the 0.1 release from <http://svn.thomas-lotze.de/svn-public/Ophelia/tags/Ophelia-0.1.tar.gz>. Ophelia is currently used to deliver its author's private web site. -- Thomas

cx_Logging 1.2
by Anthony Tuininga 21 Jul '06

21 Jul '06

What is cx_Logging? cx_Logging is a Python extension module which operates in a fashion similar to the logging module that ships with Python 2.3 and higher. It also has a C interface which allows applications to perform logging independently of Python. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Changed macros to support building with the Microsoft compiler as requested by Christopher Mioni. 2) Added keywords arguments for the StartLogging() method as requested by Christopher Mioni. 3) Use __DATE__ and __TIME__ to determine the date and time of the build rather than passing it through directly. 4) Added support for getting a file object for the file that is currently being logged to or None if no logging is taking place.
