On behalf of the Python development team and the Python community, I'm happy to announce the release candidate 1 of Python 2.5.6. This is a source-only release that only includes security fixes.

The histogram package (http://docs.danse.us/histogram) provides a simple yet fundamental data structure for scientific data reduction/analysis. Features: • Carries both data and error bars and has a default implementation for error propagation • Flexible slicing to get sub-histograms • Easy access to data as numpy arrays • Dump/load histograms in hdf format • Quick plot using matplotlib Links: • Homepage: http://docs.danse.us/histogram • Installation: http://docs.danse.us/histogram/0.2/install.html • Python API tutorial: http://docs.danse.us/histogram/0.2/python-interface.html Bug reports and any comments are very much appreciated!

RSFile 1.1 released
by Pascal Chambon 14 Apr '11

14 Apr '11

I'm pleased to announce the first bugfix release of the "RSFile" package. Issues addressed: - rejection of unicode keys in kwargs arguments, in some versions of py2.6 - indentation bug swallowing some errors on file opening ---- RSFile aims at providing python with a cross-platform, reliable, and comprehensive file I/O API. It's actually a partial reimplementation of the io module, as compatible possible (it passes latest stdlib io tests), which offers a set of new - and possibly very useful - features: shared/exclusive file record locking, cache synchronization, advanced opening flags, handy stat getters (size, inode...), shortcut I/O functions etc. Unix users might particularly be interested by the workaround that this library provides, concerning the catastrophic fcntl() lock semantic (when any descriptor to a file is closed, your process loses ALL locks acquired on it through other streams). RSFile has been tested with py2.6, py2.7, and py3.2, on win32, linux and freebsd systems, and should theoretically work with IronPython/Jython/PyPy (on Mac OS X too). The technical documentation of RSFile includes a comprehensive description of concepts and gotchas encountered while setting up this library, which could prove useful to anyone interested in getting aware about gory file I/O details. The implementation is currently pure-python, as integration with the C implementation of io module raises lots of issues. So if you need heavy performances, standard python streams will remain necessary. But for most programs and scripts, which just care about data integrity, RSFile should be a proper choice. Downloads: http://pypi.python.org/pypi/RSFile/1.1 Documentation: http://bytebucket.org/pchambon/python-rock-solid-tools/wiki/index.html Regards, Pascal Chambon PS : Due to miscellaneous bugs of python core and stdlib io modules which have been fixed relatively recently, it's advised to have an up-to-date minor version of python (be it 2.6, 2.7 or 3.2) to benefit from RSFile.

ANN: bbfreeze 0.97.3
by schmir＠gmail.com 12 Apr '11

12 Apr '11

Hi all, I uploaded bbfreeze 0.97.3 to the python package index. bbfreeze creates standalone executables from python scripts (similar to py2exe). bbfreeze works on windows and unix-like operating systems, but does not support OS X. bbfreeze is able to freeze multiple scripts, handles egg files, namespace packages and tracks binary dependencies. Changes in this release include: - exclude ms-win-api-* and query.dll. - make py parse minimal set of options required to run py.test on the frozen executable. - link with /LARGEADDRESSAWARE on win32 - ensure RPATH of application loader has the right value. try to fix it with patchelf if not. - set dont_write_bytecode and no_user_site flags if they are available. - handle pip installed namespace packages More information can be found at the python package index: http://pypi.python.org/pypi/bbfreeze/ Cheers, - Ralf
