by Emile Anclin 23 Mar '10

23 Mar '10

Hi, We are happy to announce astng 0.20.0 and pylint 0.20.0 releases. Pylint http://www.logilab.org/project/pylint is a static code checker based on Astng, both depending on logilab-common 0.49. Astng http://www.logilab.org/project/logilab-astng builds an enhanced Abstract Syntax Tree for Pylint. Astng 0.20.0 is a major refactoring and speed improvement, all along fixing a lot of important bugs: http://www.logilab.org/project/logilab-astng/0.20.0 Pylint 0.20.0 uses the new Astng, and fixes a lot of bugs too, adding some new functionalities: #5564: Parameters with leading "_" shouldn't count as "local" variables #18860: warn on assert( a, b ?) #9776: warning if return or break inside a finally #9982: specific message for NotImplemented exception For a full list, check http://www.logilab.org/project/pylint/0.20.0 We would like to thank all people who contributed to this release, especially PYLINT : * Colin Moris' patch closed #9263: no W0613 for __init__ (method does not use all of its arguments) * Johnson Fletcher implemented #18860, new W0199 message on assert (a, b) * Daniel Harding, Jonathan Hartley and Pierre Rouleau solved the windows batch files problems. * Chmouel Boudjnah solved #19339: pylint.el : non existing py-mod-map ASTNG : * Edward K. Ream / Tom Fleck patch closes #19641 (maximum recursion depth exceeded) . * Winfried Plapper pointed out and fixed bugs in astng.nodes_as_string . Also, we would thank all people who found new bugs, added interesting tickets and helped with their suggestions to improve pylint and keep the project alive. -- Emile Anclin <emile.anclin(a)logilab.fr> http://www.logilab.fr/ http://www.logilab.org/ Informatique scientifique & et gestion de connaissances

[ANN] PyInstaller 1.4
by Giovanni Bajo 22 Mar '10

22 Mar '10

Hello, I'm happy to announce PyInstaller 1.4, the first formal release after several years of quiet development. http://www.pyinstaller.org === What it is === PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, and Mac OS X. It's similar to py2exe/py2app, but it is multiplatform and with many advanced features. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. === Features === * Packaging of Python programs into standard executables, that work on computers without Python installed. * Multiplatform: works under Windows, Linux and Irix. Experimental Mac OS X support available. * Multiversion: works under any version of Python from 1.5 up to 2.6. NOTE: Support for Python 2.6+ on Windows is not included in this release yet. Please see this page for a working patch: http://www.pyinstaller.org/wiki/Python26Win * Flexible packaging mode: * Single directory: build a directory containing an executable plus all the external binary modules (.dll, .pyd, .so) used by the program. * Single file: build a single executable file, totally self-contained, which runs without any external dependency. * Custom: you can automate PyInstaller to do whatever packaging mode you want through a simple script file in Python. * Explicit intelligent support for many 3rd-packages (for hidden imports, external data files, etc.), to make them work with PyInstaller out-of-the-box. * Full single-file EGG support: .egg files are automatically packaged by PyInstaller as-is, so that all features are supported at runtime as well (entry points, etc.). * Automatic support for binary libraries used through ctypes (see http://www.pyinstaller.org/wiki/CtypesDependencySupport for details). * Support for automatic binary packing through the well-known UPX compressor. * Support for code-signing executables on Windows. * Optional console mode (see standard output and standard error at runtime). * Selectable executable icon (Windows only). * Fully configurable version resource section in executable (Windows only). * Support for building COM servers (Windows only). === ChangeLog === For those already using older versions of PyInstaller, the full changelog for this release can be found here: http://www.pyinstaller.org/browser/tags/1.4/doc/CHANGES.txt === Feedback === We're eager to listent to your feedback on using PyInstaller: Ticketing system: http://www.pyinstaller.org/newticket Mailing list: http://groups-beta.google.com/group/PyInstaller -- Giovanni Bajo :: Develer S.r.l. rasky(a)develer.com :: http://www.develer.com Blog: http://giovanni.bajo.it Last post: ctypes support in PyInstaller

onlinepayment v1.0.0 released
by Sam Tregar 22 Mar '10

22 Mar '10

onlinepayment v1.0.0 - a generic Python API for making online payments This module provides an API wrapper around a variety of payment providers. Using this module you can write code that will work the same regardless of the payment provider in use. Examples:: from onlinepayment import OnlinePayment # connect to authorize.net, setup auth with login and key auth= { 'login': 'YOUR LOGIN HERE', 'key': 'YOUR KEY HERE' } op = OnlinePayment('authnet', test_mode=True, auth=auth) # or for paypal, setup auth with user, pass, vendor and product: auth= { 'username': 'YOUR USERNAME HERE', 'password': 'YOUR PASSWORD HERE', 'vendor': 'YOUR VENDOR HERE', 'product': 'YOUR PRODUCT HERE' } # connect to PayPal op = OnlinePayment('paypal', test_mode=True, auth=auth) # charge a card try: result = op.sale(first_name = 'Joe', last_name = 'Example', address = '100 Example Ln.', city = 'Exampleville', state = 'NY', zip = '10001', amount = '2.00', card_num = '4007000000027', exp_date = '0530', card_code = '1234') except conn.TransactionDeclined: # do something when the transaction fails except conn.CardExpired: # tell the user their card is expired except conn.ProcessorException: # handle all other possible processor-generated exceptions generically # examine result, the values returned here are processor-specific success = result.success code = result.code message = result.message trans_id = result.trans_id # you can get the raw data returned by the underlying processor too orig = result.orig Installation ============ Before you can use this module you must install one or more payment processors. To install the PayPal payflowpro package:: # easy_install pytz # easy_install python-payflowpro To install the zc.authorizedotnet package and the authorize package (for recurring support):: # easy_install zc.authorizedotnet # easy_install authorize If you want authorize.net support you'll need to install a patched version of zc.ssl. Hopefully someday this will be released by the Zope devs, but so far I haven't heard anything back. Download the zc.ssl source package from http://pypi.python.org/pypi/zc.ssl/, then unpack:: # tar zxvf zc.ssl-1.1.tar.gz # cd zc.ssl-1.1 Now download and apply my zc-ssl-timeout.patch:: # wget http://python-onlinepayment.googlecode.com/svn/trunk/zc-ssl-timeout.patch # patch -p1 < /zc-ssl-timeout.patch And install the patched module:: # python setup.py install (You may also need to edit setup.py and remove the 'ssl-for-setuptools' dependecy. I did, although it may be a quirk of my Python install rather than a general problem.) Once you have a payment processor you can install this module:: # easy_install onlinepayment For more information see: http://pypi.python.org/pypi/onlinepayment/1.0.0

[ANN] TurboGears 1.1.1 released
by Christoph Zwerschke 22 Mar '10

22 Mar '10

On behalf of the TurboGears Team, I am pleased to announce that TurboGears 1.1.1 is available for download at http://turbogears.org and the Python package index http://pypi.python.org/pypi/TurboGears TurboGears 1.1.1 is the first bugfix release of the TurboGears 1.1 branch, which is the evolution of the TurboGears 1 codebase. The 1.1 branch uses SQLAlchemy as the default database layer and Genshi as the standard templating engine, just like TurboGears 2.0, while keeping full backward compatibility with TurboGears 1.0. What is TurboGears? ------------------- TurboGears is a rapid development, "front-to-back", open source web meta-framework. Its aim is to simplify and speed up the development of modern web applications written in the Python programming language. TurboGears is designed around the model-view-controller architecture, much like Struts or Ruby on Rails, and takes the best Python web components available (hence "meta-framework") and combines them into one easy-to-install, documented whole. What's new? ----------- For a comprehensive list of changes, as always, see the changelog in our Trac at http://trac.turbogears.org/wiki/ChangeLog How to install? --------------- The easiest way to install TurboGears 1.1.1 is via setuptools: [sudo] easy_install -f http://turbogears.org/download/ TurboGears We recommend that you install TurboGears into its own virtual environment using the virtualenv tool: [sudo] easy_install virtualenv virtualenv --no-site-packages /path/to/tgenv source /path/to/tgenv/bin/activate easy_install -f http://turbogears.org/download/ TurboGears How is it related to TurboGears 2? ---------------------------------- TurboGears 1.1.1 is based on the original TG 1.0 codebase and still uses CherryPy 2 as the underlying web application server. It is fully backward compatible with TG 1.0; porting an application using SQLObject and Kid to use SQLAlchemy and Genshi is easiliy achieved. TurboGears 2 has almost the same API as TurboGears 1, but builds on Pylons as the underlying web engine. Most new development for TurboGears now happens in version 2, but we will continue to provide bugfix releases for the TG 1.1 branch as well, and we are also working on a TG 1.5 branch which will be based on CherryPy 3 instead of CherryPy 2. Our current roadmap for the TG 1.5 branch is here: http://docs.turbogears.org/1.5/DevPlans Share & enjoy! -- Christoph Zwerschke

RSON 0.06 released
by Patrick Maupin 21 Mar '10

21 Mar '10

I am pleased to announce the release of RSON 0.06. The goal of the RSON project is to create a file format that is easy to edit, diff, and version control, that is a superset of JSON and smaller than YAML. I consider this release to be feature complete on the file format, and I believe the pure Python 2.x decoder (parser) to be production worthy (for users who do not need the speed of a C based decoder). The project is at: http://rson.googlecode.com/ The manual with syntax examples is at: http://rson.googlecode.com/files/rson_0_06_manual.pdf Discussions at: http://groups.google.com/group/rson-discuss

[RELEASED] Python 3.1.2
by Benjamin Peterson 21 Mar '10

21 Mar '10

On behalf of the Python development team, I'm joyful to announce the second bugfix release of the Python 3.1 series, Python 3.1.2. This bug fix release fixes numerous issues found in 3.1.1, and is considered a production release. The Python 3.1 version series focuses on the stabilization and optimization of the features and changes that Python 3.0 introduced. For example, the new I/O system has been rewritten in C for speed. File system APIs that use unicode strings now handle paths with undecodable bytes in them. Other features include an ordered dictionary implementation, a condensed syntax for nested with statements, and support for ttk Tile in Tkinter. For a more extensive list of changes in 3.1, see http://doc.python.org/3.1/whatsnew/3.1.html or Misc/NEWS in the Python distribution. To download Python 3.1.2 visit: http://www.python.org/download/releases/3.1.2/ A list of changes in 3.1.2 can be found here: http://svn.python.org/projects/python/tags/r312/Misc/NEWS The 3.1 documentation can be found at: http://docs.python.org/3.1 Bugs can always be reported to: http://bugs.python.org Enjoy! -- Benjamin Peterson Release Manager benjamin at python.org (on behalf of the entire python-dev team and 3.1.2's contributors)
