cx_Oracle 4.1.1
by Anthony Tuininga 16 Dec '05

16 Dec '05

What is cx_Oracle? cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a few exceptions. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Add support for dropping a connection from a session pool. 2) Add support for write only attributes "module", "action" and "clientinfo" which work only in Oracle 10g as requested by Egor Starostin. 3) Add support for pickling database errors. 4) Use the previously created bind variable as a template if available when creating a new variable of a larger size. Thanks to Ted Skolnick for the initial patch. 5) Fixed tests to work properly in the Python 2.4 environment where dates and timestamps are different Python types. Thanks to Henning von Bargen for pointing this out. 6) Added additional directories to search for include files and libraries in order to better support the Oracle 10g instant client. 7) Set the internal fetch number to 0 in order to satisfy very picky source analysis tools as requested by Amaury Fogeot d'Arc. 8) Improve the documentation for building and installing the module from source as some people are unaware of the standard methods for building Python modules using distutils. 9) Added note in the documentation indicating that the arraysize attribute can drastically affect performance of queries since this seems to be a common misunderstanding of first time users of cx_Oracle. 10) Add a comment indicating that on HP-UX Itanium with Oracle 10g the library ttsh10 must alos be linked against. Thanks to Bernard Delmee for the information. Anthony Tuininga

ANN: cElementTree 1.0.4 (december 13, 2005)
by Fredrik Lundh 15 Dec '05

15 Dec '05

effbot.org proudly presents release 1.0.4 of the cElementTree library, a fast and very efficient implementation of the ElementTree API, for Python 2.1 and later. On typical documents, it's 15-20 times faster than the Python version of ElementTree, and uses 2-5 times less memory. cElementTree 1.0.4 is 1.0.2 plus 2.3.5/2.4.2 compatibility fixes for copy/deepcopy (previously released as 1.0.3, as binaries only), new "pi" and "comment" targets in XMLParser, plus the ability to link against "pyexpat" instead of "expat" (this requires Python 2.5). The library is available as C source code, and as Windows installers for recent Python versions. Get your copy here: http://effbot.org/downloads#celementtree The cElementTree module uses some support functions from the standard ElementTree library, and will not work properly without it. If you haven't installed it already, you can get it from: http://effbot.org/downloads#elementtree enjoy /F

Flightdeck-UI Online development release 0.5.0 available
by George Belotsky 15 Dec '05

15 Dec '05

The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general-purpose user interfaces. The Flightdeck-UI Online 0.5.0 development release focuses on some code cleanup and documentation (mostly based on analysis with pylint) starting from the previous stable release, version 0.4.0. See the homepage: "http://www.openlight.com/fdui" or download directly from: "http://openlight.com/fdui/downloads/fdui-online-0.5.0.tar.gz". What is Flightdeck-UI --------------------- The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. The project has released the following packages. * Flightdeck-UI Online is a Web-based monitoring system/dashboard, which allows you to create multiple control panels to observe a diverse set of variables. You view these control panels entirely through a web browser (requires Flash). * Flightdeck-UI Multi-Variable Monitor(MVM) is a monitoring system/dashboard application that you install locally. It runs under both Windows and Linux. MVM includes a graphical editor (with theme support) for creating monitoring consoles. * Flightdeck-UI Library is a collection of virtual instruments that you can use in your own programs. Both Flightdeck-UI Online and Flightdeck-UI MVM use the library. Flightdeck-UI Online and Flightdeck-UI MVM share the same plugin architecture. The online version, however, is capable of monitoring each plugin at a different sampling rate. Both applications can track multiple heterogeneous data sources (hosts on the Internet, embedded devices, etc.) simultaneously. Plugins can use threads, simple synchronous I/O, or asynchronous I/O; the distributions contain examples of each type. For example, almost any Unix command that you enter manually via the shell can be automatically executed by Flightdeck-UI Online or Flightdeck-UI MVM, and the results displayed by the system's virtual instruments. The author welcomes ideas and suggestions: please email them directly to "python(a)openlight.com". Best Wishes, George Belotsky.

ANN: Amara XML Toolkit 1.1.7
by Uche Ogbuji 14 Dec '05

14 Dec '05

http://uche.ogbuji.net/tech/4suite/amara ftp://ftp.4suite.org/pub/Amara/ Changes since Amara 1.1.6: * Deprecate xml_text_content property * Add xml_child_text property that concatenates all immediate child text nodes (no recursive descent) * Change unicode coercion for documents and elements to recurse through all descendant text (now analogous to XPath's string() coercion) * Return added or removed node in - xml_append - xml_insert_after - xml_insert_before - xml_remove_child - xml_remove_child_at * Update allinone bundle to 4Suite 1.0b3 * Packaging fixes Amara XML Toolkit is a collection of Python tools for XML processing-- not just tools that happen to be written in Python, but tools built from the ground up to use Python idioms and take advantage of the many advantages of Python. Amara builds on 4Suite [http://4Suite.org], but whereas 4Suite focuses more on literal implementation of XML standards in Python, Amara focuses on Pythonic idiom. It provides tools you can trust to conform with XML standards without losing the familiar Python feel. The components of Amara are: * Bindery: data binding tool (a very Pythonic XML API) * Scimitar: implementation of the ISO Schematron schema language for XML; converts Schematron files to Python scripts * domtools: set of tools to augment Python DOMs * saxtools: set of tools to make SAX easier to use in Python * Flextyper: user-defined datatypes in Python for XML processing There's a lot in Amara, but here are highlights: Amara Bindery: XML as easy as py -------------------------------- Bindery turns an XML document into a tree of Python objects corresponding to the vocabulary used in the XML document, for maximum clarity. For example, the document <monty> <python spam="eggs">What do you mean "bleh"</python> <python ministry="abuse">But I was looking for argument</python> </monty> Becomes a data structure such that you can write binding.monty.python.spam In order to get the value "eggs" or binding.monty.python[1] In order to get the value "But I was looking for argument". There are other such tools for Python, and what makes Anobind unique is that it's driven by a very declarative rules-based system for binding XML to the Python data. You can register rules that are triggered by XPattern expressions specialized binding behavior. It includes XPath support and supports mutation. Bindery is very efficient, using SAX to generate bindings. Scimitar: Schematron for Pytthon -------------------------------- Merged in from a separate project, Scimitar is an implementation of ISO Schematron that compiles a Schematron schema into a Python validator script. You typically use scimitar in two phases. Say you have a schematron schema schema1.stron and you want to validate multiple XML files against it, instance1.xml, instance2.xml, instance3.xml. First you run schema1.stron through the scimitar compiler script, scimitar.py: scimitar.py schema1.stron The generated file, schema1.py, can be used to validate XML instances: python schema1.py instance1.xml Which emits a validation report. Amara DOM Tools: giving DOM a more Pythonic face ------------------------------------------------ DOM came from the Java world, hardly the most Pythonic API possible. Some DOM-like implementations such as 4Suite's Domlettes mix in some Pythonic idiom. Amara DOM Tools goes even further. Amara DOM Tools feature pushdom, similar to xml.dom.pulldom, but easier to use. It also includes Python generator-based tools for DOM processing, and a function to return an XPath location for any DOM node. Amara SAX Tools: SAX without the brain explosion ------------------------------------------------ Tenorsax (amara.saxtools.tenorsax) is a framework for "linerarizing" SAX logic so that it flows more naturally, and needs a lot less state machine wizardry. License ------- Amara is open source, provided under the 4Suite variant of the Apache license. See the file COPYING for details. Installation ------------ Amara 1.1.7 requires Python 2.4 or more recent. If you do not have 4Suite XML 1.0b2 or better, grab the Amara-allinone package. If you already have 4Suite XML installed, grab the stand along Amara package. In either case, unpack to a convenient location and run: python setup.py install -- Uche http://uche.ogbuji.net http://copia.ogbuji.net

ANN: 4Suite XML 1.0b3
by Uche Ogbuji 14 Dec '05

14 Dec '05

Today we release 4Suite XML 1.0 beta 3, now available from Sourceforge and ftp.4suite.org. As of the last release (1.0b2) 4Suite is split into three separate packages: 4Suite XML - XML, XPath, XSLT, related technologies and support libraries 4Suite RDF - RDF processing libraries and stand-alone DBMS 4Suite Repository - XML and RDF repository This is a release of just the first component. Highlights of changes in 4Suite XML since the last release ------------------ * 4Suite now has native DTD validation for Domlette and Saxlette, implemented in C. PyXML (xmlproc) is no a requirement for validation, and thus PyXML is no longer required for any feature in 4Suite. For Domlette validation, simply use ValidatingReader. For Saxlette validation, use P.setFeature(xml.sax.handler.feature_validation, True). Also new to Saxlette are: DTDHandler, DeclHandler and ErrorHandler. * New Ft.Xml.Lib.BaseUri function, which attempts to implement the semantics of the baseURI DOM Level 3 attribute as a stop-gap until some improvements can be made directly in Domlette. * New Ft.Lib.Uri.Relativize function, which produces context-sensitive relative references from absolute URIs. * Platform fixes for 64-bit Intel/AMD and HP-UX * Deprecate Ft.Xml.ParsePath and Ft.Xml.Xslt.TransformPath (whose duties are now also taken up by Ft.Xml.Parse and Ft.Xml.Xslt.Transform) * Deprecate category metadata property for XSLT extension elements * Bug fixes, improvements to performance and documentation 4Suite is a comprehensive platform for XML and RDF processing, with base libraries and a server framework. It is implemented in Python and C, and provides Python and XSLT APIs, Web and command line interfaces. 4Suite XML is the core set of XML, XPath, XSLT, related technologies and support libraries. The manual is included in the documents, or you can browse it online at http://uche.ogbuji.net/tech/4suite/etc/CoreManual.html For general information, see: http://4suite.org http://uche.ogbuji.net/tech/4Suite/ For the files, see: ftp://ftp.4suite.org/pub/4Suite/ Sources: ftp://ftp.4suite.org/pub/4Suite/4Suite-XML-1.0b3.tar.gz ftp://ftp.4suite.org/pub/4Suite/4Suite-XML-1.0b3.tar.bz2 ftp://ftp.4suite.org/pub/4Suite/4Suite-XML-1.0b3.zip Windows installer: ftp://ftp.4suite.org/pub/4Suite/4Suite-XML-1.0b3.win32-py2.2.exe ftp://ftp.4suite.org/pub/4Suite/4Suite-XML-1.0b3.win32-py2.3.exe ftp://ftp.4suite.org/pub/4Suite/4Suite-XML-1.0b3.win32-py2.4.exe You can also get the files on Sourceforge: https://sourceforge.net/projects/foursuite/ https://sourceforge.net/project/showfiles.php?group_id=39954 Documentation: In the locations specified above, with filenames of the form 4Suite-XML-docs-1.0b3.* Release notes ------------------ The current installation directory layout document tells where package files are installed: http://4suite.org/docs/installation-locations.xhtml For insulation from Domlette implementation changes, developers should always use the generic Ft.Xml.Domlette APIs (rather than, say Ft.Xml.cDomlette). -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://fourthought.com http://copia.ogbuji.net http://4Suite.org Articles: http://uche.ogbuji.net/tech/publications/

ReSend: ANN: EasyGuider 0.1 Released!
by limodou 14 Dec '05

14 Dec '05

I'm sorry for resend the letter again. Because the whole project is rename to a new name. = What's it = It's a GUI toolkit based on wxPython. So if you want to use it you need to install wxPython on your box. The main idea of it is Data Driven. Because I found many times, what I want just a GUI interface to gain some data from the user, and I don't care about the beauty of the interface. And if I have time, I can promote the GUI interface later. In the earlier of the project, what I want just is quicker and quicker. And I also realized that, the GUI interface is easy to change, but the data is not the same. So I want to made a GUI toolkit to implement that: a GUI auto creating toolkit based on data driven. That is why the EasyGuider be found. There is lack of documents, but I'll do my best to do that. So according the idea, the main work you need to do is design the data model, and other things is left for EasyGuider. But the data model I designed is very simple, just a tuple list, so you can very easily to write the model. = What's the status of the project = It's still on developing. And main document is written in Chinese, I'm sorry for that. But if you have any question, you can send me email directly, I'll very glad to discuss with you. = Where to download = You can download it at here http://wiki.woodpecker.org.cn/moin/EasyGuider/?action=AttachFile&do=get&tar… maillist: http://groups.google.com/group/EasyGuider wiki: http://wiki.woodpecker.org.cn/moin/EasyGuider -- I like python!
