Ann: rom 0.20 - Redis object mapper for Python
by Josiah Carlson 13 Sep '13

13 Sep '13

Hey everyone, As time progresses, so does my Redis object mapper. The "rom" package is a Redis object mapper for Python. It sports an interface similar to Django's ORM, SQLAlchemy + Elixir, or Appengine's datastore. The changelog for recent releases can be seen below my signature. You can find the package at: https://www.github.com/josiahcarlson/rom https://pypi.python.org/pypi/rom And docs can be found at: http://pythonhosted.org/rom/ Please CC me on any replies if you have any questions or comments. Thank you, - Josiah #----------------------------------- 0.20 ------------------------------------ [changed] Added exception when performing .all(), .execute(), or .count() on query objects that have had no filters or attribute ordering provided. This addresses issue #12. [changed] Moved column definitions to their own module, shouldn't affect any normal uses of rom. [added] For users of Redis 2.6 and later, there is a beta Lua-enabled writing option that allows for multiple unique columns on models. In some cases, this may improve performance when writing many entities very quickly. [added] The ability to reload an entity from Redis, optionally discarding any modifications to the object itself. Check out the documentation for Model.refresh(), Session.refresh(), and Session.refresh_all() [added] Tests for the newly changed/added features. [changed] Tests no longer use flushdb() - all test models/indexes/etc. are prefixed with RomTest, and we find/delete such keys before and after any tests are run. Now anyone can reasonably run the test suite. #----------------------------------- 0.19 ------------------------------------ [fixed] Thanks to a bug report by https://github.com/MickeyKim , was notified of a bug when using unique indexes, which is now fixed and has a testcase. #----------------------------------- 0.18 ------------------------------------ [fixed] Thanks to a bug report by https://github.com/MickeyKim , was notified and received an interim patch for a bug that could cause deleted entities to be resurrected on session.commit() or session.flush() . This has now been fixed and a testcase has been added. #----------------------------------- 0.17 ------------------------------------ [added] LGPL 3 licensing option.

ANN: eGenix PyRun - One file Python Runtime 1.3.0
by eGenix Team: M.-A. Lemburg 11 Sep '13

11 Sep '13

________________________________________________________________________ ANNOUNCING eGenix PyRun - One file Python Runtime Version 1.3.0 An easy-to-use single file relocatable Python run-time - available for Linux, Mac OS X and Unix platforms, with support for Python 2.5, 2.6 and 2.7 This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-PyRun-1.3.0-GA.html ________________________________________________________________________ INTRODUCTION Our new eGenix PyRun combines a Python interpreter with an almost complete Python standard library into a single easy-to-use executable, that does not require a system wide installation and is fully relocatable. eGenix PyRun's executable only needs 11MB, but still supports most Python application and scripts - and it can be further compressed to just 3-4MB using upx. Compared to a regular Python installation of typically 100MB on disk, this makes eGenix PyRun ideal for applications and scripts that need to be distributed to many target machines, client installations or customers. It makes "installing" Python on a Unix based system as simple as copying a single file. We have been using the product internally in our mxODBC Connect Server since 2008 with great success and have now extracted it into a stand-alone open-source product. We provide both the source archive to build your own eGenix PyRun, as well as pre-compiled binaries for Linux, FreeBSD and Mac OS X, as 32- and 64-bit versions. The binaries can be downloaded manually, or you can let our automatic install script install-pyrun take care of the installation: ./install-pyrun dir and you're done. Please see the product page for more details: http://www.egenix.com/products/python/PyRun/ ________________________________________________________________________ NEWS This is a new minor release of eGenix PyRun, which comes with updates to the latest Python releases and includes a number of compatibility enhancements. New Features ------------ * Upgraded eGenix PyRun to work with and use Python 2.7.5 per default. * Upgraded eGenix PyRun to use Python 2.6.8 as default Python 2.6 version. * PyRun will now create a symlink from "pyrunX.X" to "pythonX.X" and "pyrunX.X" to "python" in the bin/ dir to enhance compatibility with scripts and applications that hardwire the name of the Python interpreter to "python". Other Changes ------------- * Removed the compiler package from being compiled into PyRun. If needed, it can be installed separately. Note that the compiler package needs the parser module which is not compiled into PyRun either, but is still available as extension module. * Removed the Tkinter Python module from being compiled into PyRun. If needed, it can be installed separately. Note that the Tkinter module needs the _tkinter C module, which is not compiled into PyRun either, but is still available as extension module. * Fixed sys.argv when using interactive mode to default to ['']. * All eGenix PyRun distribution packages are now GPG signed with our release key and come with MD5 and SHA1 hashes to check for download corruption. install-pyrun Quick Installation Enhancements --------------------------------------------- Since version 1.1.0, eGenix PyRun includes a shell script called install-pyrun, which greatly simplifies installation of eGenix PyRun. It works much like the virtualenv shell script used for creating new virtual environments (except that there's nothing virtual about PyRun environments). https://downloads.egenix.com/python/install-pyrun With the script, an eGenix PyRun installation is as simple as running: ./install-pyrun targetdir We have enhanced this script somewhat since the last release: * install-pyrun now defaults to always installing the most recent setuptools and pip versions from PyPI. * install-pyrun now installs setuptools instead of distribute, after the two projects got merged and continued under the older name. * Added new option --pyrun-executable to define an alternative name for the executable, which is then also used when installing setuptools and pip, e.g. "python" for even better compatibility with standard Python. * install-run will now prefer curl over wget when downloading packages from PyPI. * install-pyrun local distribution options will now also work with relative paths. * install-pyrun now defaults to installing setuptools 1.1.1 and pip 1.4.1 when looking for local downloads of these tools. * The short options in install-pyrun now also have corresponding long option names. Other Changes ------------- * Fixed SyntaxWarning in pyrunX.X: name 'pyrun_script' is assigned to before global declaration global pyrun_script Presentation at EuroPython 2012 ------------------------------- Marc-André Lemburg, CEO of eGenix, gave a presentation about eGenix PyRun at EuroPython 2012 last year. The talk video as well as the slides are available on our website: http://www.egenix.com/library/presentations/EuroPython2012-eGenix-PyRun/ ________________________________________________________________________ LICENSE eGenix PyRun is distributed under the eGenix.com Public License 1.1.0 which is an Open Source license similar to the Python license. You can use eGenix PyRun in both commercial and non-commercial settings without fee or charge. Please see our license page for more details: http://www.egenix.com/products/python/PyRun/license.html The package comes with full source code. ________________________________________________________________________ DOWNLOADS The download archives and instructions for installing eGenix PyRun can be found at: http://www.egenix.com/products/python/PyRun/ As always, we are providing pre-built binaries for all common platforms: Windows 32/64-bit, Linux 32/64-bit, FreeBSD 32/64-bit, Mac OS X 32/64-bit.

IronPython 2.7.4 Released
by Jeff Hardy 08 Sep '13

08 Sep '13

On behalf of the IronPython team, I'm happy to announce the final release of IronPython 2.7.4[1]. This release includes everything from IronPython 2.7.3 and earlier. Like all IronPython 2.7-series releases, .NET 4 is required to install it. Installing this release will replace any existing IronPython 2.7-series installation. Assemblies for embedding are provided for .NET 3.5, .NET 4, .NET 4.5, and Silverlight 5. IronPython is an implementation of Python that targets Microsoft's .NET Framework and the open-source Mono framework. It aims to be as compatible as possible with Python 2.7 while taking advantage of the .NET Framework's capabilities. It is also easily embedded in .NET applications to provide scripting capabilities. Improvements in IronPython 2.7.4 are mainly a collection of bug fixes, many of which are directed at getting IPython working. Specific improvements include: * Many fixes to the ast module (thanks to Pawel Jasinski) * A bunch of fixes to locale and tty handling (also courtesy of Pawel) designed to get IPython working. * .NET 4.5 builds, courtesy of Aleksander Heintz * Other fixes from Michael van der Kolff, Fraser Tweedale, and Igor (WildOgr) * A bunch of small fixes backported from the master branch Android and Silverlight 4 assemblies have been dropped from this version. The Android assemblies need some more work to be usable with Xamarin.Android, and Silverlight 4 is just plain dead. For Visual Studio integration, check out Python Tools for Visual Studio which has support for IronPython as well as CPython, and many other fantastic features. IronPython 2.7.4 is also available for embedding via NuGet. The main package is IronPython, and the standard library is in IronPython.StdLib. - Jeff [1] https://ironpython.codeplex.com/releases/view/90087

PyDev 2.8.2 released
by Fabio Zadrozny 05 Sep '13

05 Sep '13

Hi All, PyDev 2.8.2 has been released Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com Become a supporter and help to keep it going forward: https://sw-brainwy.rhcloud.com/ Release Highlights: ------------------------------- * The type inference engine now accepts comments in the format **#@type a: str** to get the type. * Interpreter configuration properly deals with characters with ampersand. * Interactive console can now work with PySide and wxPython to create widgets without blocking. * Debugger now working properly with Jython 2.1. * Markups in sphinx or epydoc format can now have a different color in docstrings. * Code-completion for the sphinx markup is provided in docstrings. * Fixed issue when resolving module names (which could make PyDev find modules as Lib.math instead of math if the interpreter folder was added to the PYTHONPATH and not only the Lib folder). * When configuring project source folders (PYTHONPATH), it's possible to make use of the PROJECT_DIR_NAME variable. * **Patches by Trey Greer**: * PyLint 1.0 is now properly supported. * **Patches by Jonah Graham:** * Fixed issue in interactive console interaction with XML-RPC. * Interactive console history is saved to persistent location. * It's possible to filter variables in the variables view menu (can be activated with Ctrl+F10 focusing the variables view > PyDev, select/deselect filters). * Eclipse variables are expanded in the initial interpreter commands for the interactive console. * An evaluate button (same as Ctrl+Alt+Enter) is now available in the toolbar. * **Patches by by Anselm Kruis:** * Fixed issues related to having the interpreter or workspace in locations with non-ascii characters. * **Patches by Jeremy Carroll:** * It's now possible to use PEP-8 style imports (default now, can be unconfigured at window > preferencs > pydev > editor > code style > imports). * It's possible to configure the organize imports to remove unused imports (must be enabled in window > preferencs > pydev > editor > code style > imports). * **Patches by Andrew Ferrazzutti:** * Better heuristics to discover file in workspace related to open files when debugging. * Improvements in the PyDev project configuration and wizard. * It's possible to mark/unmark folders as source folders with a right-click context menu. * Auto-Configuration of interpreter streamlined. * **Patches by Andre Berg:** * It's possible to have a change action which will keep a variable updated when file is changed (i.e.: __date__ = '2013-01-01' would be updated when file is saved to a new date). What is PyDev? --------------------------- PyDev is a plugin that enables users to use Eclipse for Python, Jython and IronPython development -- making Eclipse a first class Python IDE -- It comes with many goodies such as code completion, syntax highlighting, syntax analysis, refactor, debug and many others. Cheers, -- Fabio Zadrozny ------------------------------------------------------ Software Developer PyDev - Python Development Environment for Eclipse http://pydev.org http://pydev.blogspot.com
