From bgg at object-craft.com.au Thu Mar 25 15:33:50 2010 From: bgg at object-craft.com.au (Ben Golding) Date: Thu, 25 Mar 2010 15:33:50 +1100 Subject: [albatross-users] Albatross 1.40 release Message-ID: OVERVIEW Albatross is a small toolkit for developing highly stateful web applications. The toolkit has been designed to take a lot of the pain out of constructing intranet applications although you can also use Albatross for deploying publicly accessed web applications. In slightly more than 5300 lines of Python (according to pycount) you get the following: * An extensible HTML templating system similar to DTML including tags for: - Conditional processing. - Macro definition and expansion. - Sequence iteration and pagination. - Tree browsing. - Lookup tables to translate Python values to arbitrary template text. * Application classes which offer the following features: - Optional server side or browser side sessions. - The ability to place Python code for each page in a dynamically loaded module, or to place all page processing code in a single mainline. * The ability to deploy applications as CGI, FastCGI, mod_python or a pure python HTTP server by changing less than 10 lines of code. The toolkit application functionality is defined by a collection of fine grained mixin classes. Nine different application types and six different execution contexts are prepackaged, you are able to define your own drop in replacements for any of the mixins to alter any aspect of the toolkit semantics. Application deployment is controlled by your choice of either cgi, FastCGI, mod_python, or BaseHTTPServer Request class. It should be possible to develop a Request class for Medusa or Twisted to allow applications to be deployed on those platforms with minimal changes. Albatross comes with over 180 pages of documentation. HTML and PDF formatted documentation is available from the toolkit homepage.

The Albatross documentation has been converted to ReST, and uses Sphinx to render this to HTML and PDF formats. * Albatross Forms A simple HTML form generation and validation framework has been added to Albatross (as an optional extension under the module name albatross.ext.form). Bug Fixes --------- * Redirects were not calling req.return_code() - for FastCGI deployment, this meant the request would hang [11164]. * The python built-in __import__() gained extra arguments with python 2.6 - the decode session import hook has been changed to pass all arguments (positional and keyword) [14823]. * When rendering tags to HTML, the handling of the noescape attribute was not consistently honoured. Attribute rendering has been moved to the common Tag base class as the write_attrib() method [15398]. * Relaxed tag recognition regular expressions, so that malformed tag attributes with no value, such as , are still recognised as valid Albatross tags, albeit with a null name attribute (which subsequently generates an error) [15398]. Miscellaneous Changes --------------------- * Miscellaneous changes to RedHat, Ubuntu, Solaris and OS X packaging rules. * Reorganised the unit tests to eliminate the use of explicitly assembled test suites, relying instead on the unittestmodule to collect methods of TestCase subclasses. The documentation example tests were also reimplemented as TestCase subclasses, allowing them to be run via common test driver. -------------- next part -------------- A non-text attachment was scrubbed...
