ANN: MV3D-0.60 Released!
by Michael Handverger 08 Aug '11

08 Aug '11

I am pleased to announce the release of MV3D version 0.60! This release focused on scalability of worlds and includes support for splitting a single area across multiple server processes with automatic load balancing and redundancy. Areas can now be connected together using gateways to build worlds limited in size only by the amount of available hardware. The Overseer Cluster Management tool was upgraded in order to better handle many processes across multiple physical servers. Camera controls across all content tools have been unified. Better support for Panda3D clients was added as well. MV3D is an open source virtual world and multiplayer game framework written in Python which uses Twisted for networking. It was designed with scalability in mind and is able to distribute a world across as many servers as needed while dynamically balancing the load. The simulation framework is not specifically slanted towards any one genre of online game, and can just as easily be used for a space game as a fantasy setting. Objects on an MV3D server are simulated using the ODE physics engine. A single server can host thousands of simulated objects. MV3D supports either Python-Ogre or Panda3D on the client. For more information on MV3D and this or future releases, please visit the website at http://www.mv3d.com . The full release notes for version 0.6 are available online at this URL: http://www.mv3d.com/trac/browser/tags/mv3d-0.60/release-notes.txt . For further inquiries, feel free to stop by our IRC channel on irc.freenode.net #MV3D. Here's a short video of the new demo world: http://www.youtube.com/watch?v=iZiKr0t1TqU Enjoy, Mike

Cython 0.15 released
by robertwb 06 Aug '11

06 Aug '11

We are excited to announce the release of Cython 0.15, which is a huge step forward in achieving full Python language coverage as well as many new features, optimizations, and bugfixes. Download: http://cython.org/ or http://pypi.python.org/pypi/Cython == Major Features == * Generators (yield) - Cython has full support for generators, generator expressions and coroutines. http://www.python.org/dev/peps/pep-0342/ * The nonlocal keyword is supported. * Re-acquiring the gil: with gil - works as expected within a nogil context. * OpenMP support: http://docs.cython.org/0.15/src/userguide/parallelism.html * Control flow analysis prunes dead code and emits warnings and errors about uninitialised variables. * Debugger command cy set to assign values of expressions to Cython variables and cy exec counterpart cy_eval(). * Exception chaining http://www.python.org/dev/peps/pep-3134/ * Relative imports http://www.python.org/dev/peps/pep-0328/ * The with statement has its own dedicated and faster C implementation. * Improved pure syntax including cython.cclass, cython.cfunc, and cython.ccall. http://docs.cython.org/0.15/src/tutorial/pure.html * Support for del. * Boundschecking directives implemented for builtin Python sequence types. * Several updates and additions to the shipped standard library pxd files https://github.com/cython/cython/tree/master/Cython/Includes * Forward declaration of types is no longer required for circular references. Note: this will be the last release to support Python 2.3; Python 2.4 will be supported for at least one more release. == General improvements and bug fixes == This release contains over a thousand commits including hundreds of bugfixes and optimizations. The bug tracker has not been as heavily used this release cycle, but is still useful http://trac.cython.org/cython_trac/query?status=closed&group=component&orde… == Incompatible changes == * Uninitialized variables are no longer initialized to None and accessing them has the same semantics as standard Python. * globals() now returns a read-only dict of the Cython module's globals, rather than the globals of the first non-Cython module in the stack * Many C++ exceptions are now special cases to give closer Python counterparts. This means that except+ functions that formally raised generic RuntimeErrors may raise something else such as ArithmaticError. == Known regressions == * The inlined generator expressions (introduced in Cython 0.13) were disabled in favour of full generator expression support. This induces a performance regression for cases that were previously inlined. == Contributors == Many thanks to: Francesc Alted, Haoyu Bai, Stefan Behnel, Robert Bradshaw, Lars Buitinck, Lisandro Dalcin, John Ehresman, Mark Florisson, Christoph Gohlke, Jason Grout, Chris Lasher, Vitja Makarov, Brent Pedersen, Dag Sverre Seljebotn, Nathaniel Smith, and Pauli Virtanen

ANN: Webware for Python 1.1 released
by Christoph Zwerschke 04 Aug '11

04 Aug '11

A new version 1.1 of the venerable Webware for Python web framework is now available for download at http://downloads.sourceforge.net/webware/Webware-1.1.tar.gz. This release offers some major new features, e.g. a WSGI adapter, sessions based on shelve or Memcached, MiddleKit supporting SQLite. Webware requires Python 2.4 now. The code base has been cleaned up and modernized very much; all the old cruft that was only there to support older Python versions has been removed. The older Python versions are still supported via the latest bugfix version 1.0.3 of the 1.0 branch which has been released along with the current version 1.1. You can find more info on the Webware for Python homepage at http://www.webwareforpython.org/ Support is available via the Webware for Python mailing lists at https://sourceforge.net/mail/?group_id=4866 -- Christoph Zwerschke

pyPEG 1.4 released
by Volker Birk 03 Aug '11

03 Aug '11

New: This release fixes some bugs with packrat parsing. Homepage: http://fdik.org/pyPEG Download: http://fdik.org/pyPEG/pyPEG.py Python is a nice scripting language. It even gives you access to it's own parser and compiler. It also gives you access to different other parsers for special purposes like XML and string templates. But sometimes you may want to have your own parser. This is what's pyPEG for. And pyPEG supports Unicode. What is PEG? PEG means Parsing Expression Grammar. It's something like the idea of Regular Expressions for context free languages; a very clear explanation you'll find in the Wikipedia article about PEG. With PEGs you can describe the same languages like with BNF (and they're even similar). What is a Parser-Interpreter? Common parsers are not using PEGs and top-down parsing, but LR(n) or LL(n) and bottom-up parsing. This results in the idea of implementing parser generators. Because with LR(n) or LL(n) parsers you need to calculate out a DFA first, usually you let the parser generator do this for you. The result is a parser implementation for your BNF grammar, which was the input. One could call a parser generator a compiler from BNF to a parser implementation. A Parser-Interpreter does work as an interpreter instead of being such a compiler. Just give your grammar as input, and it parses the described language out of text. There will be no program generated.

[ANN]: 'tren' Cross-Platform Batch Renaming Tool, Version 1.242 Released
by Tim Daneliuk 03 Aug '11

03 Aug '11

'tren' Version 1.242 is now released and available for download at: http://www.tundraware.com/Software/tren The last public release was 1.239. --------------------------------------------------------------------- What's New In This Release? --------------------------- Updated code for backward compatibility with versions of Python prior to 2.6.x. NEW: None OTHER: Documentation updates (minor). What Is 'tren'? ------------------ 'tren' is a general purpose file and directory renaming tool. Unlike commands like 'mv', 'tren' is particularly well suited for renaming *batches* of files and/or directories with a single command line invocation. 'tren' eliminates the tedium of having to script simpler tools to provide higher-level renaming capabilities. 'tren' is also adept at renaming only *part of an existing file or directory name* either based on a literal string or a regular expression pattern. You can replace any single, group, or all instances of a given string in a file or directory name. 'tren' implements the idea of a *renaming token*. These are special names you can embed in your renaming requests that represent things like the file's original name, its length, date of creation, and so on. There are even renaming tokens that will substitute the content of any environment variable or the results of running a program from a shell back into the new file name. 'tren' can automatically generate *sequences* of file names based on their dates, lengths, times within a given date, and so on. In fact, sequences can be generated on the basis of any of the file's 'stat' information. Sequence "numbers" can be ascending or descending and the count can start at any initial value. Counting can take place in one of several internally defined counting "alphabets" (decimal, hex, octal, alpha, etc.) OR you can define your own counting alphabet. This allows you to create sequences in any base (2 or higher please using any symbol set for the count. 'tren' is written in pure Python and requires Python version 2.4.x or later. (It *may* run with Python 2.3.x, but has not been tested with this older release.) 'tren' is known to run on various Unix-like variants (FreeBSD, Linux, MacOS X, cygwin) as well as Windows. It will also take advantage of 'win32all' Python extensions on a Windows system, if they are present. --------------------------------------------------------------------- Complete details of all fixes, changes, and new features can be found in the WHATSNEW.txt and documentation files included in the distribution. A FreeBSD port has been submitted as well.
