ANN: PyJudy 1.0
by Andrew Dalke 06 Nov '05

06 Nov '05

Over the last three weeks of on-and-off work I've developed and have just released PyJudy 1.0, a wrapper to the Judy sparse dynamic array library. It is available for download at http://dalkescientific.com/Python/PyJudy.html Judy, from http://judy.sourceforge.net/ , is ... a C library that provides a state-of-the-art core technology that implements a sparse dynamic array. Judy arrays are declared simply with a null pointer. A Judy array consumes memory only when it is populated, yet can grow to take advantage of all available memory if desired. Judy's key benefits are scalability, high performance, and memory efficiency. A Judy array is extensible and can scale up to a very large number of elements, bounded only by machine memory. Since Judy is designed as an unbounded array, the size of a Judy array is not pre-allocated but grows and shrinks dynamically with the array population. Continuing from the PyJudy page at http://dalkescientific.com/Python/PyJudy.html PyJudy arrays are similar to Python dictionaries and sets. The primary difference is that PyJudy keys are sorted; by unsigned value if an integer, byte ordering if a string and object id if a Python object. In addition to wrapping the underlying Judy functions, PyJudy implements a subset of the Python dictionary interface for the JudyL and JudySL API and a subset of the set interface for the Judy1 API, along with some extensions for iterating a subrange of the sorted keys, values and items. In my performance tests I found that overall JudyL arrays were a bit slower than Python dictionaries. Part of that might be my inexperience with the details of writing Python extensions. Part might be that JudyL arrays are sorted. I found that the Judy1 arrays were faster than the set class in Python 2.4. It'll be interesting to see how Raymond's new set implementation affects that. I did not do any memory comparisons. PyJudy is distributed under the MIT license because that has few upper-case letters than the BSD one.

05 Nov '05

================ atomixlib 0.3.0 ================ Available at : http://www.defuze.org/oss/atomixlib/ What's new? ================ * It breaks the compatibility with previous version. Mainly you do not need to pass the current atom element being constructed to the Atomix methods. Instead the Atomix class keeps an handle to that element internally. * It adds a lot more documentation via docstrings and an epydoc version of the API. * It fixes some issues with XHTML content * It is more flexible for creating the atom document (feed or entry based). * It improves performances of atomixlib since 0.2.0 Get atomixlib ================ http://www.defuze.org/oss/atomixlib/download/atomixlib-0.3.0.tgz What's atomixlib? ================ A Python module to facilitate Atom 1.0 documents generation. License ================ BSD Credits ================ I would like to thank Uche Ogbuji for discussing atomixlib so much and giving me some very neat ideas. Enjoy! - Sylvain Hellegouarch sh defuze.org ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

pypy 0.8.0 released
by holger krekel 03 Nov '05

03 Nov '05

pypy-0.8.0: Translatable compiler/parser and some more speed ============================================================== The PyPy development team has been busy working and we've now packaged our latest improvements, completed work and new experiments as version 0.8.0, our third public release. The highlights of this third release of PyPy are: - Translatable parser and AST compiler. PyPy now integrates its own compiler based on Python own 'compiler' package but with a number of fixes and code simplifications in order to get it translated with the rest of PyPy. This makes using the translated pypy interactively much more pleasant, as compilation is considerably faster than in 0.7.0. - Some Speed enhancements. Translated PyPy is now about 10 times faster than 0.7 but still 10-20 times slower than CPython on pystones and other benchmarks. At the same time, language compliancy has been slightly increased compared to 0.7 which had already reached major CPython compliancy goals. - Some experimental features are now translateable. Since 0.6.0, PyPy shipped with an experimental Object Space (the part of PyPy implementing Python object operations and manipulation) implementing lazily computed objects, the "Thunk" object space. With 0.8.0 this object space can also be translated preserving its feature additions. What is PyPy (about)? ------------------------------------------------ PyPy is a MIT-licensed research-oriented reimplementation of Python written in Python itself, flexible and easy to experiment with. It translates itself to lower level languages. Our goals are to target a large variety of platforms, small and large, by providing a compilation toolsuite that can produce custom Python versions. Platform, Memory and Threading models are to become aspects of the translation process - as opposed to encoding low level details into a language implementation itself. Eventually, dynamic optimization techniques - implemented as another translation aspect - should become robust against language changes. Note that PyPy is mainly a research and development project and does not by itself focus on getting a production-ready Python implementation although we do hope and expect it to become a viable contender in that area sometime next year. PyPy is partially funded as a research project under the European Union's IST programme. Where to start? ----------------------------- Getting started: http://codespeak.net/pypy/dist/pypy/doc/getting-started.html PyPy Documentation: http://codespeak.net/pypy/dist/pypy/doc/ PyPy Homepage: http://codespeak.net/pypy/ The interpreter and object model implementations shipped with the 0.8 version can run on their own and implement the core language features of Python as of CPython 2.4. However, we still do not recommend using PyPy for anything else than for education, playing or research purposes. Ongoing work and near term goals --------------------------------- At the last sprint in Paris we started exploring the new directions of our work, in terms of extending and optimising PyPy further. We started to scratch the surface of Just-In-Time compiler related work, which we still expect will be the major source of our future speed improvements and some successful amount of work has been done on the support needed for stackless-like features. This release also includes the snapshots in preliminary or embryonic form of the following interesting but yet not completed sub projects: - The OOtyper, a RTyper variation for higher-level backends (Squeak, ...) - A JavaScript backend - A limited (PPC) assembler backend (this related to the JIT) - some bits for a socket module PyPy has been developed during approximately 16 coding sprints across Europe and the US. It continues to be a very dynamically and incrementally evolving project with many of these one-week workshops to follow. PyPy has been a community effort from the start and it would not have got that far without the coding and feedback support from numerous people. Please feel free to give feedback and raise questions. contact points: http://codespeak.net/pypy/dist/pypy/doc/contact.html have fun, the pypy team, (Armin Rigo, Samuele Pedroni, Holger Krekel, Christian Tismer, Carl Friedrich Bolz, Michael Hudson, and many others: http://codespeak.net/pypy/dist/pypy/doc/contributor.html) PyPy development and activities happen as an open source project and with the support of a consortium partially funded by a two year European Union IST research grant. The full partners of that consortium are: Heinrich-Heine University (Germany), AB Strakt (Sweden) merlinux GmbH (Germany), tismerysoft GmbH (Germany) Logilab Paris (France), DFKI GmbH (Germany) ChangeMaker (Sweden), Impara (Germany)
