SCWEB 0.1 to be released
by Philippe C. Martin Oct. 25, 2005

Oct. 25, 2005

Dear all, I intend to release withing the next very few week the version 0.1 of SCWEB, a cross-platform web authentication platform _mostly_ written in Python. SCWEB will come with server modules (cgi), client modules (Firefox extension/plugin and XPCOM modules) All modules are operational except for the XPCOM part. I wished to announce the coming SCWEB now because I have opened a blog (www.snakecard.com/WordPress) so I might potentially get important feedback prior to the release. SCWEB will be distributed under the GPL license. Comments are quite welcome: www.snakecard.com/WordPress Regards, Philippe Martin

Subject: ANN: 4Suite XML 1.0b2
by Uche Ogbuji Oct. 25, 2005

Oct. 25, 2005

Today we release 4Suite XML 1.0 beta 2, now available from Sourceforge and ftp.4suite.org. The most important development is that 4Suite is being 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 The main reasons for this split are * The core XML libraries are much more mature than the rest of 4Suite, and indeed have been 1.0 quality for a long time * The size of the overall package gives pause to people who just want a basic XML processing toolkit The plans are to push 4Suite XML to 1.0 and then focus on 4Suite RDF and 4Suite Repository. Highlights of changes in 4Suite XML since the last release -- * New user manual and improvements to API documentation * Domlette: Convenience parse functions Ft.Xml.Parse and Ft.Xml.ParsePath * XSLT: XSLT processing convenience functions Ft.Xml.Xslt.Transform and Ft.Xml.Xslt.TransformPath * XML Catalogs: improved implementation and compliance * XInclude and XPointer: improved coverage of the spec * Yet more significant performance increases throughout: * XSLT: Fixed huge performance bug with large, complex transforms * Combined XML string routines into a single module Ft.Xml.Lib.XmlString - IsQName, IsNCName, IsName and IsNmtoken implemented in C - Removed Python versions of implemented functions * Domlette: switched struct allocs to use the Python object allocator (speed) * Domlette: changed callback qualified names to be reported as a struct instead of a string with parts separated by a special character (speed & memory) * Domlette: changed Node.prefix to be computed runtime rather than stored (memory) * Domlette: added interning of individual name parts (speed & memory) * Domlette: new parsing function ParseFragment (to replace NonvalParse(parseAsEntity=True)) * Saxlette: Ft.Xml.Domlette.SaxWalker class for walking a DOM and emitting SAX events as if from a parse * Saxlette: suspend and resume support, which allows users to create SAX applications using Python generator semantics * Saxlette: new ContentHandler (Ft.Xml.Sax.DomBuilder) for constructing Domlette Documents * Saxlette: improved compatability with PySAX * Saxlette: support for full LexicalHandler and ContentHandler interfaces * Fix case-sensitivity clashes in modules in some Windows set-ups * Improved DocBook utilities * moved SourceArgToInputSource from Ft.Xml.Lib to Ft.Lib.CommandLine.CommandLineUtil * RELAX NG: Add support for wxs string type facets maxLength, minLength and pattern * XPath: Added extension function typing information. Currently only used for documentation purposes but could lead to automatic type conversions. * Installation locations should be accessed in the form Ft.GetConfigVar('xxxDIR'), rather than the original Ft.xxxDIR * XPointer: new Ft.Xml.XPointer.Compile convenience function * XSLT: Add i18n in XSLT support (f:setup-translations and f:gettext ext elements) * XSLT: implement Extended versions of XSLT elements for debugging and execution tracing (Ft.Xml.Xslt.ExtendedProcessingElements) * XSLT: Support UTF-8 BOM in xsl:output and exsl:document (extension attribute f:utfbom)Support safegaurs against file overwrite in exsl:document (extension attribute f:overwrite-safeguard) * XSLT: Add prefix to namespace mapping to 4XSLT command line * Internal detail: Added UCS4/UTF-32 internal encoding support to Expat to allow for direct copying of XML_Char into Py_UNICODE thus preventing an unnecessary decoding step on our part. This also greatly simplifies XML_Char routines. 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.

OSDC 2005 Registration
by Richard Jones Oct. 24, 2005

Oct. 24, 2005

G'day folks, This is a quick note to let you know that registrations for Australia's second Open Source Developers' Conference are now open. Last year's conference was a huge hit with 60 high quality talks running in three streams over three days. If you weren't able to join us last year make sure you don't miss out this year! If you register before EARLY BIRD DATE you will receive a conference t-shirt and financial discount. You can register at http://www.osdc.com.au/registration/index.html OSDC is a grass roots-style conference designed by developers for developers, covering open source languages, tools, libraries, operating systems, licences and business models. We're booking 3 lecture rooms each day for the 3 days to hold a new set 60 different talks. Talks topics range from the safety Perl's Safe.pm, to rapid game development in Python, to using PHP for unorthodox applications, to utilizing Java's Groovy in your next application. We also have talks on conference skills, database integration, digital forensics, Gumstix and Nagios. You can find the full list of speakers and talk titles at http://osdc2005.cgpublisher.com/session_descriptions.html Because there are so many good talks, you can be certain that there will be something that interests you in every talk session. Each day will start with a keynote by our excellent keynote speakers. These include Damian Conway, Jonathan Oxer, Richard Farnsworth (from the Australian Synchrotron) and Anthony Baxter. The rest of the day will be filled with up to 5 hours of talks and plentiful food breaks. Our catering choices should result in you being extraordinarily well fed throughout the days of the conference. There will also be several BOFs (yet to be organised), lots of opportunities to socialise, a semi-formal dinner, a partners' programme and other usual conference stuff.

CherryPy-2.1.0-final released
by remi＠cherrypy.org Oct. 23, 2005

Oct. 23, 2005

Hello everyone, I am happy to announce the release of CherryPy-2.1.0 If is the result of 6 months of intense development since the last stable release and the work of a growing number of contributors. CherryPy has become increasingly popular these past few months (the mailing lists now have more than 500 people) and it is also used in other popular products such as Subway and Turbogears. This release is a major step forward for CherryPy. It is packed with new features and bug fixes. Here are the main improvements in this release: - New WSGI interface, which allow CherryPy sites to be deployed on any WSGI server. People are already running it on mod_python, FastCGI, SCGI, IIS or CherryPy's own built-in HTTP server. - New implementation for sessions, which supports multiple backends - Built-in list of convenient "filters" for things like gzip compression, XHTML validation, caching, unicode decoding/encoding, authentication, XML-RPC wrapper, etc ... These filters can easily be enabled/disabled through configuration. - New "development" mode which provides things like autoreload (no need to manually restart your server when you make a change), logging of page stats, etc ... - Better handling of file uploads - Internal implementation now uses generators everywhere (no more StringIO) - New built-in HTTP server implementation *************** About CherryPy: CherryPy-2 is a pythonic, object-oriented web development framework. Here is a sample Hello, World in CherryPy-2: # import cherrypy # class HelloWorld: # @cherrypy.expose # def index(self): # yield "<html><body>" # yield "Hello world!" # yield "</body></html>" # cherrypy.root = HelloWorld() # cherrypy.server.start() Main properties: - this code starts a multi-threaded HTTP server that dispatches requests to methods - requests like "http://domain/dir/page?arg1=va l1&arg2=val2" are mapped to "dir.page(arg1='val1', arg2='val2')" - CherryPy also supports "RESTful" URLs like http://domain/book/science/9 - requests are mapped to an object tree that is "mounted" on cherrypy.root (for instance: "cherrypy.root.user", "cherrypy.root.user.remi", ...) - method must be explicitly exposed with a decorator "@cherrypy.expose" (or "index.exposed = True" for Python-2.3) Remi. http://www.cherrypy.org

FarPy GUIE v0.2
by dberlin＠gmail.com Oct. 23, 2005

Oct. 23, 2005

http://farpy.holev.com/ GUIE (GUI Editor) provides a simple WYSIWYG GUI editor for wxPython. The program was made in C# and saves the GUI that was created to a XML format I called GUIML. This GUIML is a pretty standrad representation of the GUI created with the program. Next, GUIE takes these GUIML files and translates it to wxPython Python code. You may ask yourself why I took the extra step? Why didn't I go straight from C# controls to wxPython code? Why is GUIML neccessary? Well, it isn't. It is there simply for people (or maybe I) to take the GUIML and convert it to other languages. This, by effect can convert this tool from a Python GUI editor, to "any programming language with a GUI module" GUI editor. Changes (as of v0.2) Added: multi-window support!! Fix: error saving file after opening it Added: Calendar control Added: extra information status bar Fix: problem in dialogs causing .guiml to not show up Fix: controls aligning to correct position only after shown All over bug fix! (about 20 bugs fixed!) http://farpy.holev.com/

[ANN] PyLint 0.8
by Sylvain Thénault Oct. 22, 2005

Oct. 22, 2005

Hi there ! I'm very pleased to announce the new 0.8 release of PyLint. I've promised this release for a long time now, and finally got the time to do it :D. This release includes a lot of bug fixes and enhancements. Notice that a major change in this release is a new dependancy to the astng package which has been extracted from logilab-common. This package is downloadable from http://www.logilab.org/projects/astng. What's new ? ------------ * check names imported from a module exists in the module (E0611), patch contributed by Amaury Forgeot d'Arc * print a warning (W0212) for methods that could be a function (implements #9100) * new --defining-attr-methods option on classes checker * new --acquired-members option on the classes checker, used when --zope=yes to avoid false positive on acquired attributes (listed using this new option) (close #8616) * generate one E0602 for each use of an undefined variable (previously, only one for the first use but not for the following) (implements #1000) * make profile option saveable * fix Windows .bat file, patch contributed by Amaury Forgeot d'Arc * fix one more false positive for E0601 (access before definition) with for loop such as "for i in range(10): print i" (test func_noerror_defined_and_used_on_same_line) * fix false positive for E0201 (undefined member) when accessing to __name__ on a class object * fix astng checkers traversal order * fix bug in format checker when parsing a file from a platform using different new line characters (close #9239) * fix encoding detection regexp * fix --rcfile handling (support for --rcfile=file, close #9590) What is pylint ? ---------------- Pylint is a python tool that checks if a module satisfy a coding standard. Pylint can be seen as another pychecker since nearly all tests you can do with pychecker can also be done with Pylint. But Pylint offers some more features, like checking line-code's length, checking if variable names are well-formed according to your coding standard, or checking if declared interfaces are truly implemented, and much more (see http://www.logilab.org/projects/pylint/ for the complete check list). The big advantage with Pylint is that it is highly configurable, customizable, and you can easily write a small plugin to add a personal feature. The usage it quite simple : $ pylint mypackage.mymodule This command will output all the errors and warnings related to the tested code (here : mypackage.mymodule), will dump a little summary at the end, and will give a mark to the tested code. Pylint is free software distributed under the GNU Public Licence.

[ANN] ASTNG 0.13
by Sylvain Thénault Oct. 22, 2005

Oct. 22, 2005

I'm pleased to announce the release of the Logilab's ASTNG package. This package has been extracted from the logilab-common package, which will be kept for some time for backward compatibility but will no longer be maintained (this explains that this package is starting with the 0.13 version number, since the fork occurs with the version released in logilab-common 0.12). See below for a description of what's inside... What's new ? ------------ * .locals and .globals on scoped node handle now a list of references to each assigment statements instead of a single reference to the first assigment statement. * fix bug with manager.astng_from_module_name when a context file is given (notably fix ZODB 3.4 crash with pylint/pyreverse) * fix Compare.as_string method * fix bug with lambda object missing the "type" attribute * some minor refactoring What is astng ? --------------- The aim of this module is to provide a common base representation of python source code for projects such as pychecker, pyreverse, pylint... Well, actually the development of this library is essentialy governed by pylint's needs. It extends class defined in the compiler.ast module with some additional methods and attributes. Instance attributes are added by a builder object, which can either generate extended ast (let's call them astng ;) by visiting an existant ast tree or by inspecting living object. Methods are added by monkey patching ast classes.
