A summary of new features features and improvements in this release: - Implemented Local Shared Object (LSO) - ByteArray now implements DataInput and DataOutput instead of StringIOProxy - remoting.client mostly fully supports the predefined headers - Fixed argument positioning for RemoteObject processing - Remoting client now supports authentication - Proper encoding for aliased subclassed builtin types, specifically flex.ArrayCollection - Added support for easy encoding of Django object queries (Foo.objects.all()) - Added 'expose_request' argument to DjangoGateway to expose the underlying HTTP Request object as the first arg in the called services Check out the download page [1] and installation instructions [2]. Got questions? First stop is the mailing list [3], but we also hang out on [4].

ANN: cssutils 0.9.5a1
by Christof Hoeke 13 Jan '08

13 Jan '08

what is it ---------- A Python package to parse and build CSS Cascading Style Sheets. main changes since 0.9.4b1 -------------------------- for full details for 0.9.5a1 see the relevant CHANGELOG: http://cssutils.googlecode.com/svn/tags/TAG_0.9.5a1/CHANGELOG.txt A few (minor) non-backwards compatible changes have been made, please see http://cssutils.googlecode.com/svn/tags/TAG_0.9.5a1/documentation/migrate.t… for migration help. 0.9.5a1 + **API CHANGE**: ``Property.name`` is now the same as ``Property.normalname`` which is DEPRECATED now. To access the literal name (the value which was available in ``name`` until now) use ``Property.literalname``. For most cases where a property name is used the new behaviour makes more sense, therefor the change. **Do not use ``normalname`` anymore, it will probably be removed for release 1.0.** + **API CHANGE**: iterating over ``css.CSSStyleDelcaration`` yields now *effective* properties only and not *all* properties set in the declaration. E.g. from ``color: red; c\olor: green`` only one Property is returned which has the value ``green``. To retrieve *all* properties use ``CSSStyleDeclaration.getProperties(all=True)``. Reason for this change is that for most cases the new default makes more sense. - **FEATURE**: ``css.CSSStyleDelcaration`` supports ``in`` now. Expected is a Property or a name of a property which is checked if already in the style declaration - **FEATURE**: ``css.Selector`` has a **readonly** property ``specificity`` now which is calculated as described at http://www.w3.org/TR/css3-selectors/#specificity - **FEATURE**: Added ``css.CSSStyleDeclaration.getProperty(name, normalize=True)`` which returns the effective Property object for ``name``. - FEATURE: Implemented http://csswg.inkedblade.net/spec/css2.1#issue-23, URI may be ``URL(...)`` or ``u\r\6c(...)`` now + **BUGFIX**: Priority of Properties is acknowledged by all methods of ``css.CSSStylesDeclaration`` now. license ------- cssutils is published under the LGPL. download -------- for download options for see http://cthedot.de/cssutils/ cssutils needs Python 2.4 or higher (tested with Python 2.5 on Vista only) bug reports, comments, etc are very much appreciated! thanks, Christof

SQLObject 0.10.0b1
by Oleg Broytmann 11 Jan '08

11 Jan '08

Hello! I'm pleased to announce the 0.10.0b1, the first beta release of a new SQLObject branch, 0.10. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.10.0b1 News and changes: http://sqlobject.org/News.html What's New ========== Features & Interface -------------------- * Dropped support for Python 2.2. The minimal version of Python for SQLObject is 2.3 now. * Removed actively deprecated attributes; lowered deprecation level for other attributes to be removed after 0.10. * SQLBuilder Select supports the rest of SelectResults options (reversed, distinct, joins, etc.) * SQLObject.select() (i.e., SelectResults) and DBConnection.queryForSelect() use SQLBuilder Select queries; this make all SELECTs implemented internally via a single mechanism. * SQLBuilder Joins handle SQLExpression tables (not just str/SQLObject/Alias) and properly sqlrepr. * SQLBuilder tablesUsedDict handles sqlrepr'able objects. * Added SQLBuilder ImportProxy. It allows one to ignore the circular import issues with referring to SQLObject classes in other files - it uses the classregistry as the string class names for FK/Joins do, but specifically intended for SQLBuilder expressions. See tests/test_sqlbuilder_importproxy.py. * Added SelectResults.throughTo. It allows one to traverse relationships (FK/Join) via SQL, avoiding the intermediate objects. Additionally, it's a simple mechanism for pre-caching/eager-loading of later FK relationships (i.e., going to loop over a select of somePeople and ask for aPerson.group, first call list(somePeople.throughTo.group) to preload those related groups and use 2 db queries instead of N+1). See tests/test_select_through.py. * Added ViewSQLObject. * Added sqlmeta.getColumns() to get all the columns for a class (including parent classes), excluding the column 'childName' and including the column 'id'. sqlmeta.asDict() now uses getColumns(), so there is no need to override it in the inheritable sqlmeta class; this makes asDict() to work properly on inheritable sqlobjects. * Changed the implementation type in BoolCol under SQLite from TINYINT to BOOLEAN and made fromDatabase machinery to recognize it. * Added rich comparison methods; SQLObjects of the same class are considered equal is they have the same id; other methods return NotImplemented. * MySQLConnection (and DB URI) accept a number of SSL-related parameters: ssl_key, ssl_cert, ssl_ca, ssl_capath. For a more complete list, please see the news: http://sqlobject.org/News.html Oleg. -- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.
