Albatross 0.05 released
by Dave Cole 12 Jan '02

12 Jan '02

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 there is no real reason why you should not use Albatross for deploying publicly accessed web applications. In slightly more than 2600 lines of Python you get the following: - An extensible HTML templating system similar to DTML including tags for: - Tree browsing. - Macro definition and expansion. - Automatic sequence pagination. - Lookup tables to translate internal program value 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 either as CGI or via mod_python by changing less than 10 lines of code. The toolkit application functionality is defined by a collection of fine grained mixin classes. Six different application types and four 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 Request class. It should be possible to develop a Request class for FastCGI or Medusa to allow applications to be deployed on those platforms with minimal changes. Albatross comes with around 120 pages of documentation. HTML, PDF and PostScript formatted documentation is available from the toolkit homepage. The toolkit homepage: http://www.object-craft.com.au/projects/albatross/ Important changes since last release: * Huge number of documentation fixes. * Documentation for macro tags has been completed. * New calendar example extension tag. * Fixed infinite recursion bug in nested macro expansion. * All interactive examples in documentation are now validated via 'make test' in the doc directory. * Lots of new unit tests. - Dave -- http://www.object-craft.com.au

ANNOUNCE: SCons 0.03 now available
by Steven Knight 11 Jan '02

11 Jan '02

Version 0.03 of SCons has been released and is available for download from the SCons web site: http://www.scons.org/ Or through the download link at the SCons project page at SourceForge: http://sourceforge.net/projects/scons/ RPM and Debian packages and a Win32 installer are all available, in addition to the traditional .tar.gz files. This release contains significant performance improvements, support for command-line redirection, building from lex (.l) and yacc (.y) files, the InstallAs method, and more than a few bug fixes. SCons is a software construction tool (build tool, make tool) written in Python. Its design is based on the design which won the Software Carpentry build tool competition in August 2000 (in turn derived from the Perl-based Cons build tool). Distinctive features of SCons include: - configuration files are Python scripts, allowing the full use of a real scripting language to solve build problems - a modular architecture allows the SCons Build Engine to be embedded in other Python software - a global view of all dependencies; no multiple passes to get everything built - the ability to scan files for implicit dependencies (#include files); - improved parallel build (-j) support - use of MD5 signatures to decide if a file has changed - easily extensible through user-defined Builder and Scanner objects An scons-users mailing list has been created for those interested in getting started using SCons. You can subscribe at: http://lists.sourceforge.net/lists/listinfo/scons-users Alternatively, we invite you to subscribe to the low-volume scons-announce mailing list to receive notification when new versions of SCons become available: http://lists.sourceforge.net/lists/listinfo/scons-announce Special thanks to Charles Crain, Steve Leblanc, and Anthony Roach for their contributions to this release. On behalf of the SCons team, --SK

RELEASED - Python 2.1.2c1
by Guido van Rossum 11 Jan '02

11 Jan '02

We've issued a release candidate of Python 2.1.2: http://www.python.org/2.1.2/ Our thanks go out to Anthony Baxter, who almost singlehandedly produced this release. We're planning a final release of 2.1.2 early next week, probably Tuesday night (Wednesday morning for Anthony :-). Please report any bugs you find to the bug tracker: http://sourceforge.net/bugs/?group_id=5470 This being a bugfix release, there are no exciting new features -- we just fixed a lot of bugs; a few are outlined below. For a complete list, please see: http://sourceforge.net/project/shownotes.php?release_id=69287 - The socket object gained a new method, 'sendall()'. This method is guaranteed to send all data - this is not guaranteed by the 'send()' method. See also SF patch #474307. The standard library has been updated to use this method where appropriate. - Fix for incorrectly swapped arguments to PyFrame_BlockSetup in ceval.c. This bug could cause python to crash. It was related to using a 'continue' inside a 'try' block. - The Python compiler package was updated to correctly calculate stack depth in some cases. This was affecting Zope Python Scripts rather badly. - Largefile support was added (but not on by default, you'll need to follow the instructions in the documentation of the posix module). --Guido van Rossum (home page: http://www.python.org/~guido/)

Pymacs 0.15
by pinard＠iro.umontreal.ca 10 Jan '02

10 Jan '02

Hi! A new release of Pymacs is available as: http://www.iro.umontreal.ca/~pinard/pymacs/pymacs.tar.gz Pymacs allows Emacs users to extend Emacs using Python, where they might have traditionally used Emacs LISP. Pymacs runs on systems having sub-processes. One bug in the `rebox.py' example was reported the day 0.14 was published. I waited a few days in case other bugs would be reported, but none shown up. So, if you have 0.14, there is no need to switch to 0.15, unless you have interest in the Pymacs example for itself. I know some users do :-). -- François Pinard http://www.iro.umontreal.ca/~pinard

pyOpenSSL 0.4.1
by Martin Sjögren 10 Jan '02

10 Jan '02

I just released version 0.4.1 of pyOpenSSL. It contains some portability fixes and windows compatability patches. Mostly, I've worked on creating decent Debian packages. I tried the bdist_rpm command for distutils so there are RPMs too, but don't blame me if they don't work, I don't know anything about RPM at all :-) Standard sourceforge download URL: http://sourceforge.net/project/showfiles.php?group_id=31249&release_id=69237 As of this writing, the links aren't there yet, but sf.net has a tendency to lag on that a bit.

mimedecode.py version 1.1.2
by Oleg Broytmann 09 Jan '02

09 Jan '02

Hello! mimedecode.py WHAT IS IT Mail users, especially in non-English countries, often find that mail messages arrived in different formats, with different content types, in different encodings and charsets. Usually this is very good because it allows us to use apropriate formats/encodings/whatever. Sometimes, though, some unification is desireable. For example, one may want to put mail messages into an archive, make HTML indicies, run search indexer, etc. In such situations converting messages to text in one character set and skipping some binary atachmetnts will be much desireable. Here is the solution - mimedecode.py. This is a program to decode MIME messages. The program expects one input file (either on command line or on stdin) which treated as an RFC822 mesage, and decoded to stdout. If the file is not an RFC822 message the file just piped to stdout one-to-one. If it is a simple RFC822 message it is just decoded as one part. If it is a MIME message with multiple parts ("attachments") all parts decoded. Decoding can be controlled by command-line options. WHAT'S NEW in version 1.1.2 Fixed a major bug in binary attachments handling. Fixed a minor wart that was found by PyChecker. WHERE TO GET Master site: http://phd.pp.ru/Software/Python/#mimedecode Faster mirror: http://phd.by.ru/Software/Python/#mimedecode Requires: Python 2.0+ (actually tested with 2.1.1), configured mailcap database.
