PyXML 0.8 is released
by loewis＠informatik.hu-berlin.de July 31, 2002

July 31, 2002

Version 0.8 of the Python/XML distribution is now available. It should be considered a beta release, and can be downloaded from the following URLs: http://prdownloads.sourceforge.net/pyxml/PyXML-0.8.tar.gz http://prdownloads.sourceforge.net/pyxml/PyXML-0.8.win32-py2.1.exe http://prdownloads.sourceforge.net/pyxml/PyXML-0.8.win32-py2.2.exe http://prdownloads.sourceforge.net/pyxml/PyXML-0.8-2.2.i386.rpm Changes in this version, compared to 0.7.1: * Python 1.5 is not supported anymore; Python 2.0 or higher is required. * Expat has been updated to 1.95.4. * pyexpat is now always built. * pyexpat now reports skipped entities. * pyexpat now can combine subsequent character data events into a single callback invocation; set the parser's buffer_text attribute to true to enable this feature. * pyexpat can now report namespace prefixes. Set the parser's namespace_prefixes attribute to true to enable this feature. * Various bugs in sgmlop have been fixed. * Various DOM Level 3 symbolic constants have been added; DOMStringSizeErr can now be spelled as DomstringSizeErr again, and ValidationErr has been defined. * Various DOM L1, L2 and L3 features have been added to minidom: userdata, isSupported, getInterface, wholeText, replaceWholeText, Entity, Notation * minidom's .toxml now allows the caller to specify an encoding. * The new module xml.dom.xmlbuilder implements the load part of the DOM L3 Load/Store spec. * The new module xml.dom.expatbuilder allows to create minidom trees more efficiently, by using expat directly (rather than using SAX). This is normally used via xml.dom.xmlbuilder. * Bugs in c14n namespace processing have been fixed. * Minor bugs in xmlproc have been fixed. * xml.sax.expatreader now invokes resolveEntity properly. * The sgmlop SAX driver now invokes skippedEntity. * The xml-howto has been updated. * Bugs in the MSIE, ADR, and NS XBEL parsers have been fixed. The Python/XML distribution contains the basic tools required for processing XML data using the Python programming language, assembled into one easy-to-install package. The distribution includes parsers and standard interfaces such as SAX and DOM, along with various other useful modules. The package currently contains: * XML parsers: Pyexpat (Jack Jansen), xmlproc (Lars Marius Garshol), sgmlop (Fredrik Lundh). * SAX interface (Lars Marius Garshol) * minidom DOM implementation (Paul Prescod, others) * 4DOM and 4XPath from Fourthought (Uche Ogbuji, Mike Olson) * Schema implementations: TREX (James Tauber) * Various utility modules and functions (various people) * Documentation and example programs (various people) The code is being developed bazaar-style by contributors from the Python XML Special Interest Group, so please send comments and questions to <xml-sig(a)python.org>. Bug reports may be filed on SourceForge: http://sourceforge.net/tracker/index.php?group_id=6473&atid=106473 For more information about Python and XML, see: http://www.python.org/topics/xml/ -- Martin v.

ANNOUNCE: scgi 0.4 released
by Neil Schemenauer July 31, 2002

July 31, 2002

Version 0.4 of the scgi package is now available from: http://www.mems-exchange.org/software/scgi/ The SCGI protocol is a replacement for the Common Gateway Interface (CGI) protocol. It is a standard for applications to interface with HTTP servers. It is similar to FastCGI but is designed to be easier to implement. Included in this package is mod_scgi, an Apache module that implements the client side of the protocol. There is also a a Python package called scgi which implements the server side of the protocol. Changes in scgi 0.4 ------------------- quixote_handler.py * Make debug() message a little more useful when we catch IOError on closing connection. scgi_server.py * Fix a bug that caused the manager process to hang. The hang was trigged when the maximum number of child processes were running and one died while the manager was trying to find an idle child to process a request. -- Neil Schemenauer <nas(a)mems-exchange.org> | MEMS Exchange Software Engineer | http://www.mems-exchange.org/

ANN: Python Spread Module 1.3 Released
by Guido van Rossum July 31, 2002

July 31, 2002

I've released version 1.3 of the Spread Module for Python: http://www.python.org/other/spread/ About the Spread Module ----------------------- This package contains a simple Python wrapper module for the Spread toolkit (see below). The wrapper is compatible with Python 2.1 and 2.2. It wraps Spread mailboxes and messages in Python objects with appropriate methods and attributes, and turns Spread errors into Python exceptions. Virtually all Spread features are accessible from Python. About Spread ------------ >From the Spread website (http://www.spread.org): Spread is a toolkit that provides a high performance messaging service that is resilient to faults across external or internal networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast and group communication support. Spread services range from reliable message passing to fully ordered messages with delivery guarantees, even in case of computer failures and network partitions. Spread is designed to encapsulate the challenging aspects of asynchronous networks and enable the construction of scalable distributed applications, allowing application builders to focus on the differentiating components of their application. Changes since release 1.2 ------------------------- - Critical bugfix: We didn't realize that the service_type argument to Spread's SP_receive() is an input parameter as well as an output parameter, and consequently didn't initialize it. Depending on what trash happened to be sitting on the stack, this could cause Spread to deliberately drop data (a backward compatibility feature in Spread triggered by passing the DROP_RECV flag in service_type on input). Enjoy! --Guido van Rossum (home page: http://www.python.org/~guido/)

CherryPy-0.4 released
by remi＠cherrypy.org July 30, 2002

July 30, 2002

We're pleased to announce the release of CherryPy-0.4. This release adds a new major feature that is very important for high-traffic web sites: caching capability. It also includes some compiler optimization. ------------------------------------------ About CherryPy: CherryPy is a Python-based tool for developing dynamic websites. It uses many powerful concepts together, which makes it unique in its approach to website development. CherryPy sits between an application server and a compiler. You write source files, compile them with CherryPy and CherryPy generates an executable containing everything to run the website (including an HTTP server). Key properties/features of CherryPy are: - Based exclusively on Python (runs everywhere Python runs) - Delivers fast, robust, and scalable websites - Developers can use OOP as well as AOP (Aspect Oriented Programming) concepts to develop websites - True separation of content and presentation - Simple but powerful templating language - "HTML editor safe" templating language (templates can go back and forth between designers and developers) - Powerful standard libraries to make your life easy Other properties/features are: - Can be linked to many databases (Oracle, Sybase, MySql, PostgreSql, ...) - Can run behind another webserver (Apache, ...) - Easy clustering and load-balancing set up for high-traffic websites - Built-in caching capability Remi. http://www.cherrypy.org
