lxml 2.2 released
by Stefan Behnel March 21, 2009

March 21, 2009

Hi all, I'm proud to announce the release of lxml 2.2 final. http://codespeak.net/lxml/ http://pypi.python.org/pypi/lxml/2.2 This is a major new, stable and mature release that takes over the stable 2.x release series. All previous 2.x releases are now officially out of maintenance. It includes a large number of bug fixes and improvements (see below for a complete changelog) that make lxml 2.2 a lot more robust than the previous 2.1 and older releases. It is therefore generally worth upgrading (and it should not be too hard to do that). This release was built with Cython 0.11 final. Have fun, Stefan What is lxml? ============== lxml is the most feature-rich and easy-to-use library for working with XML and HTML in the Python language. It's also amongst the fastest and most memory friendly XML tree libraries for Python. lxml is a pythonic, mature binding for the libxml2 and libxslt libraries that provides safe and convenient access to these libraries using the ElementTree API. It extends the ElementTree API significantly to offer support for XPath, RelaxNG, XML Schema, XSLT, C14N and much more. Changelog since lxml 2.1 ========================= 2.2 (2009-03-21) Features added * Support for standalone flag in XML declaration through tree.docinfo.standalone and by passing standalone=True/False on serialisation. Bugs fixed * Crash when parsing an XML Schema with external imports from a filename. 2.2beta4 (2009-02-27) Features added * Support strings and instantiable Element classes as child arguments to the constructor of custom Element classes. * GZip compression support for serialisation to files and file-like objects. Bugs fixed * Deep-copying an ElementTree copied neither its sibling PIs and comments nor its internal/external DTD subsets. * Soupparser failed on broken attributes without values. * Crash in XSLT when overwriting an already defined attribute using xsl:attribute. * Crash bug in exception handling code under Python 3. This was due to a problem in Cython, not lxml itself. * lxml.html.FormElement._name() failed for non top-level forms. * TAG special attribute in constructor of custom Element classes was evaluated incorrectly. Other changes * Official support for Python 3.0.1. * Element.findtext() now returns an empty string instead of None for Elements without text content. 2.2beta3 (2009-02-17) Features added * XSLT.strparam() class method to wrap quoted string parameters that require escaping. Bugs fixed * Memory leak in XPath evaluators. * Crash when parsing indented XML in one thread and merging it with other documents parsed in another thread. * Setting the base attribute in lxml.objectify from a unicode string failed. * Fixes following changes in Python 3.0.1. * Minor fixes for Python 3. Other changes * The global error log (which is copied into the exception log) is now local to a thread, which fixes some race conditions. * More robust error handling on serialisation. 2.2beta2 (2009-01-25) Bugs fixed * Potential memory leak on exception handling. This was due to a problem in Cython, not lxml itself. * iter_links (and related link-rewriting functions) in lxml.html would interpret CSS like url("link") incorrectly (treating the quotation marks as part of the link). * Failing import on systems that have an io module. 2.2beta1 (2008-12-12) Features added * Allow lxml.html.diff.htmldiff to accept Element objects, not just HTML strings. Bugs fixed * Crash when using an XPath evaluator in multiple threads. * Fixed missing whitespace before Link:... in lxml.html.diff. Other changes * Export lxml.html.parse. 2.2alpha1 (2008-11-23) Features added * Support for XSLT result tree fragments in XPath/XSLT extension functions. * QName objects have new properties namespace and localname. * New options for exclusive C14N and C14N without comments. * Instantiating a custom Element classes creates a new Element. Bugs fixed * XSLT didn't inherit the parse options of the input document. * 0-bytes could slip through the API when used inside of Unicode strings. * With lxml.html.clean.autolink, links with balanced parenthesis, that end in a parenthesis, will be linked in their entirety (typical with Wikipedia links).

ANN: eGenix mxODBC Connect 1.0.1 - Python Database Interface
by eGenix Team: M.-A. Lemburg March 19, 2009

March 19, 2009

________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Connect Python Database Interface Version 1.0.1 Our new client-server product for connecting Python applications to relational databases - from all major platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-1.0.1-GA.html ________________________________________________________________________ INTRODUCTION The mxODBC Connect Database Interface for Python allows users to easily connect Python applications to all major databases on the market today in a highly portable and convenient way. Unlike our mxODBC Python extension, mxODBC Connect is designed as client-server application, so you no longer need to find production quality ODBC drivers for all the platforms you target with your Python application. Instead you use an easy to install Python client library which connects directly to the mxODBC Connect database server over the network. This makes mxODBC Connect the ideal basis for writing cross-platform database programs and utilities in Python, especially if you run applications that need to communicate with databases such as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more, that run on Windows or Linux machines. By removing the need to install and configure ODBC drivers on the client side, mxODBC Connect greatly simplifies setup and configuration of database driven client applications, while at the same time making the network communication between client and database server more efficient and more secure. For more information, please see the product page: http://www.egenix.com/products/python/mxODBCConnect/ ________________________________________________________________________ NEWS mxODBC Connect 1.0.1 is a patch-level release of our new mxODBC Connect product. * More Robust We have made the client and server more robust in case of communication failures. Even if the client applications fail to shutdown the server connection before exiting, the server will free up resources used by the client on the server side and rollback transactions as necessary. * More Platform Support With the 1.0.1 release we are also providing much better platform support for the mxODBC Connect Client: we have fixed a problem in 1.0.0 that prevented the installation of the pre-built clients on non-Linux systems. The mxODBC Connect Client can now be installed on most platforms supported by Python, since it is written in a platform independent, portable way. The pre-built archives also make it possible to integrate the clients into build system such as buildout (used in Zope and Plone) or other distutils-based deployment systems. * Ideal for Building Bridges As a result, connecting from e.g. Mac OS X to an SQL Server database has never been easier. You can even keep the data sources you already have configured on your Windows machine and connect to them as if your application were running on the database server itself. ________________________________________________________________________ UPGRADING You are encouraged to upgrade to this latest mxODBC Connect release. When upgrading, please always upgrade both the server and the client installations to the same version - even for patch level releases. Customers who have purchased mxODBC Connect 1.0 licenses can download and upgrade their existing installations without having to purchase new licenses or upgrades. The licenses will continue to work with version 1.0.1. Users of our stand-alone mxODBC product will have to purchase new licenses from our online shop in order to use mxODBC Connect. You can request 30-day evaluation licenses by visiting our web-site or writing to sales(a)egenix.com, stating your name (or the name of the company) and the number of eval licenses that you need. http://www.egenix.com/products/python/mxODBCConnect/#Evaluation ________________________________________________________________________ DOWNLOADS The download archives as well as instructions for installation and configuration of the product can be found on the product page: http://www.egenix.com/products/python/mxODBCConnect/ Evaluation licenses for the server part are available free of charge: http://www.egenix.com/products/python/mxODBCConnect/#Evaluation The client part of mxODBC Connect is always free of charge. _______________________________________________________________________ SUPPORT Commercial support for this product is available from eGenix.com.

Roundup Issue Tracker release 1.4.8
by Richard Jones March 18, 2009

March 18, 2009

I'm proud to release version 1.4.8 of Roundup. This release fixes some regressions: - bug introduced into hyperdb filter (issue 2550505) - bug introduced into CVS export and view (issue 2550529) - bugs introduced in the migration to the email package (issue 2550531) And adds a couple of other fixes: - handle bogus pagination values (issue 2550530) - fix TLS handling with some SMTP servers (issues 2484879 and 1912923) Though some new features made it in also: - Provide a "no selection" option in web interface selection widgets - Debug logging now uses the logging module rather than print - Allow CGI frontend to serve XMLRPC requests. - Added XMLRPC actions, as well as bridging CGI actions to XMLRPC actions. - Optimized large file serving via mod_python / sendfile(). - Support resuming downloads for (large) files. If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: roundup-demo Release info and download page: http://cheeseshop.python.org/pypi/roundup Source and documentation is available at the website: http://roundup.sourceforge.net/ Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.3+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and four database back-ends (anydbm, sqlite, mysql and postgresql).
