[ANN] Komodo 7 release (Python development tools)
by Todd Whiteman Feb. 8, 2012

Feb. 8, 2012

Hello, My name is Todd. I'm the lead developer for Komodo IDE (Interactive Development Environment) and Komodo Edit (a free, open-source editor) at ActiveState. I wanted to announce that the newest version, Komodo 7, has been released: http://www.activestate.com/komodo-ide Python has long been one of the main languages supported by Komodo, so we're always getting useful feedback and suggestions. For Komodo 7, we've incorporated a lot of this feedback into enhancing our Python features. * Python Code Profiling (IDE only) Users have asked if there is a way to find out why their programs are taking so long to run. Komodo IDE 7 can show a graph of the methods and calls made by your program, so that you can detect where your CPU is being taken up. * Sophisticated Syntax Checking Choose between multiple syntax checkers like PyLint, PyFlakes and PyChecker. Provides language-specific syntax checking for CSS/JavaScript/Django inside HTML template languages like Django. * Code Collaboration (IDE only) We wanted to make pair programming easier. With the collaboration feature, multiple users can edit a document at the same time. It's kind of like Google Docs, but for code editing! * Speed With Komodo 7 you'll notice a lot snappier Komodo start-up time, lower CPU utilization - particularly when idle, and lower memory usage for large projects. * Even more... There are way more features in Komodo 7 than I can outline in a single post, so check out the online web pages for more Komodo 7 enhancements: http://www.activestate.com/komodo-ide/python-editor Again, note that Komodo comes in two different flavours: 1) Komodo Edit - completely free and fully open-source editor, offering smart code completions, syntax checking, code colorizing, sophisticated editing and more. 2) Komodo IDE - a full featured IDE, offering advanced debugging, interactive shells, code browsing, source code control, database integration, unit testing, regular expression tools and more. Try out Komodo 7 and let me know what you think. We really appreciate the support and feedback! Cheers, Todd

ANN: gcc-python-plugin 0.9
by David Malcolm Feb. 6, 2012

Feb. 6, 2012

gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the CPython interpreter within GCC, allowing you to write new compiler warnings in Python, generate code visualizations, etc. It ships with "gcc-with-cpychecker", which implements static analysis passes for GCC aimed at finding bugs in CPython extensions. In particular, it can automatically detect reference-counting errors: http://gcc-python-plugin.readthedocs.org/en/latest/cpychecker.html This release (0.9) is mostly about internal fixes: * support for gcc 4.7 prereleases * the plugin is now properly integrated with GCC's garbage collector, fixing segfaults that could happen when compiling large files (the Python wrapper objects no longer have their underlying GCC objects swept away from under them) * gcc-with-cpychecker's analysis logic has been reworked, fixing numerous bugs, and extending the scope of the checker enough to find 8 previously-missed memory-leak bugs when run upon itself. There are many other improvements. Detailed release notes can be seen at: http://gcc-python-plugin.readthedocs.org/en/latest/0.9.html Tarball releases are available at: https://fedorahosted.org/releases/g/c/gcc-python-plugin/ Prebuilt-documentation can be seen at: http://gcc-python-plugin.readthedocs.org/en/latest/index.html The project's homepage is: https://fedorahosted.org/gcc-python-plugin/ The plugin and checker are Free Software, licensed under the GPLv3 or later. Enjoy! Dave Malcolm

os.stat last accessed attribute
by Python_Junkie Feb. 3, 2012

Feb. 3, 2012

I am using the os.stat module to determine a number of file properties. I am finding that a significant number of files are having their last accessed date dynamically modified to the time that the script determines its attributes. I am not opening the files, and the script is not applying this property for all of the files. Any suggestions as to why this might be occurring. Thanks

[ANN] cdecimal-2.3 released
by Stefan Krah Feb. 2, 2012

Feb. 2, 2012

Hi, I'm pleased to announce the release of cdecimal-2.3. cdecimal is a fast drop-in replacement for the decimal module in Python's standard library. Blurb ===== cdecimal is a complete implementation of IBM's General Decimal Arithmetic Specification. With the appropriate context parameters, cdecimal will also conform to the IEEE 754-2008 Standard for Floating-Point Arithmetic. Typical performance gains over decimal.py are between 30x for I/O heavy benchmarks and 80x for numerical programs. In a PostgreSQL database benchmark, the speedup is 12x. +---------+-------------+--------------+-------------+ | | decimal | cdecimal | speedup | +=========+=============+==============+=============+ | pi | 42.75s | 0.58s | 74x | +---------+-------------+--------------+-------------+ | telco | 172.19s | 5.68s | 30x | +---------+-------------+--------------+-------------+ | psycopg | 3.57s | 0.29s | 12x | +---------+-------------+--------------+-------------+ In the pi benchmark, cdecimal often performs better than Java's BigDecimal running on Java HotSpot(TM) 64-Bit Server VM. What's New ========== o The underlying library - libmpdec - now has a very comprehensive test suite against decNumber. o libmpdec now has full support for compilers without uint64_t. o Code coverage of cdecimal has been increased to 100%. Now both libmpdec and cdecimal have 100% coverage. o Improved code for conversion of small Python integers to Decimals leads to a performance gain of around 15%. o Added real(), imag(), conjugate(), __complex__() methods. o Add Fraction and complex comparisons (enabled for Python 3.2). o Support for DecimalTuple output. Stability ========= Both cdecimal and libmpdec have an extremely conservative release policy. When new features are added, the complete test suite is run both with and without Valgrind on many different platforms. With the added tests against decNumber, this takes around 8 months on four cores. Install ======= Since cdecimal is listed on PyPI, it can be installed using pip: pip install cdecimal Windows installers are available at: http://www.bytereef.org/mpdecimal/download.html Links ===== http://www.bytereef.org/mpdecimal/index.html http://www.bytereef.org/mpdecimal/changelog.html http://www.bytereef.org/mpdecimal/download.html Checksums of the released packages ================================== 03f76f4acbb6e7f648c6efc6e424bbc1b4afb5632dac5196f840e71f603a2b4a mpdecimal-2.3.tar.gz b0fd5bec2cc6a6035bc406339d020d2f4200a7dce8e8136a2850612a06508ed1 mpdecimal-2.3.zip d737cbe43ed1f6ad9874fb86c3db1e9bbe20c0c750868fde5be3f379ade83d8b cdecimal-2.3.tar.gz 84afd94126549a3c67c3bab7437d085347f9d05c cdecimal-2.3.win-amd64-py2.6.msi ba0fbb1f9314dcef29481414a5c3496ec159df2e cdecimal-2.3.win-amd64-py2.7.msi d11bbd560e9cb9d34b0e7a068ac1c1eac5371428 cdecimal-2.3.win-amd64-py3.1.msi d024148ea603dc8e82f8371ebdfaa0e65f5a9945 cdecimal-2.3.win-amd64-py3.2.msi d196a9e0b44dcb75bbf4eda44078b766e6113f72 cdecimal-2.3.win32-py2.6.msi e2b044da6c241df0911059216821c9865cb9e4f0 cdecimal-2.3.win32-py2.7.msi 7e8b47eb3a2f50191e76f981fbe55050f13495e8 cdecimal-2.3.win32-py3.1.msi 61be767b91aab0ba0d602fb2b23f6d882cafec05 cdecimal-2.3.win32-py3.2.msi a2278910a5b447af963e1d427dbeb48f49e377be cdecimal-2.3-no-thread.win-amd64-py2.6.msi 8da96d2f1ab1a98062cd43cb4f381b47309d8c22 cdecimal-2.3-no-thread.win-amd64-py2.7.msi 85cd3ff4496aa7e0d0979d1695eef27cc7735c28 cdecimal-2.3-no-thread.win-amd64-py3.1.msi 6c179a1284aceb3a7bfc481daae1d7d60359d487 cdecimal-2.3-no-thread.win-amd64-py3.2.msi 40f245e907512c5d3602ba5993755a0b4b67ca80 cdecimal-2.3-no-thread.win32-py2.6.msi 960eb9bfd9fcf0faee6493506c1917d46536193a cdecimal-2.3-no-thread.win32-py2.7.msi 42b651ee1bf4c94611c43522d69f1965515949b8 cdecimal-2.3-no-thread.win32-py3.1.msi ec26f14c35502d1d5488d440d7bc22ad41e9ac65 cdecimal-2.3-no-thread.win32-py3.2.msi
