Poll on PyPI rating system
by "Martin v. Löwis" 13 Nov '09

13 Nov '09

PyPI (pypi.python.org) recently got a rating system which includes the option of posting comments about a package release also. Several people have expressed a strong dislike of that system and want to see it changed or removed. In order to find out what the community thinks, we are now performing a poll, at http://pypi.python.org/pypi If you have an opinion on that matter, please participate in the poll. Regards, Martin v.

[ANN] ftputil 2.4.2 released
by Stefan Schwarzer 12 Nov '09

12 Nov '09

ftputil 2.4.2 is now available from http://ftputil.sschwarzer.net/download . Changes since version 2.4.1 --------------------------- - Some FTP servers seem to have problems using *any* directory argument which contains slashes. The new default for FTP commands now is to change into the directory before actually invoking the command on a relative path (report and fix suggestion by Nicola Murino). - Calling the method ``FTPHost.stat_cache.resize`` with an argument 0 caused an exception. This has been fixed; a zero cache size now of course doesn't cache anything but doesn't lead to a traceback either. - The installation script ``setup.py`` didn't work with the ``--home`` option because it still tried to install the documentation in a system directory (report by Albrecht Mühlenschulte). As a side effect, when using the *global* installation, the documentation is no longer installed in the ftputil package directory but in a subdirectory ``doc`` of a directory determined by Distutils. For example, on my system (Ubuntu 9.04) the documentation files are put into ``/usr/local/doc``. Upgrading is recommended. What is ftputil? ---------------- ftputil is a high-level FTP client library for the Python programming language. ftputil implements a virtual file system for accessing FTP servers, that is, it can generate file-like objects for remote files. The library supports many functions similar to those in the os, os.path and shutil modules. ftputil has convenience functions for conditional uploads and downloads, and handles FTP clients and servers in different timezones. Read the documentation at http://ftputil.sschwarzer.net/documentation . License ------- ftputil is Open Source software, released under the revised BSD license (see http://www.opensource.org/licenses/bsd-license.php ). Stefan

ANN: eGenix pyOpenSSL Distribution 0.9.0-0.9.8l
by eGenix Team: M.-A. Lemburg 10 Nov '09

10 Nov '09

________________________________________________________________________ ANNOUNCING eGenix.com pyOpenSSL Distribution Version 0.9.0-0.9.8l An easy-to-install and easy-to-use distribution of the pyOpenSSL Python interface for OpenSSL - available for Windows, Mac OS X and Unix platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-pyOpenSSL-Distribution-0.9.0-0.9.… ________________________________________________________________________ INTRODUCTION The eGenix.com pyOpenSSL Distribution includes everything you need to get started with SSL in Python. It comes with an easy-to-use installer that includes the most recent OpenSSL library versions in pre-compiled form, making your application independent of OS provided OpenSSL libraries: http://www.egenix.com/products/python/pyOpenSSL/ pyOpenSSL is an open-source Python add-on that allows writing SSL/TLS- aware network applications as well as certificate management tools: http://pyopenssl.sourceforge.net/ OpenSSL is an open-source implementation of the SSL/TLS protocol: http://www.openssl.org/ ________________________________________________________________________ NEWS This new release of the eGenix.com pyOpenSSL Distribution updates the included OpenSSL version to 0.9.8l. The new OpenSSL version includes an important work-around for a serious problem in TLS, the protocol implemented and used by OpenSSL. The Man-in-the-Middle TLS protocol attack was disclosed on 2009-11-05 and is being tracked as CVE-2009-3555: http://isc.sans.org/diary.html?storyid=7534 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3555 IMPORTANT: The work-around chosen by the OpenSSL team is to disable SSL session renegotiations altogether. This can cause applications relying on this feature on the client or server side to fail. You can still download the previous version of our pyOpenSSL distribution if you run into such problems: http://www.egenix.com/products/python/pyOpenSSL/0.9.0-0.9.8k_1/ As always, we provide binaries that include both pyOpenSSL and the necessary OpenSSL libraries for all supported platforms: Windows x86, Linux x86 and x64, Mac OS X PPC and x86. Due to popular demand, we've also added .egg-file format versions of our eGenix.com pyOpenSSL Distribution for Windows and Linux to the available download options. These makes setups using e.g. zc.buildout and other egg-file based installers a lot easier. ________________________________________________________________________ DOWNLOADS The download archives and instructions for installing the package can be found at: http://www.egenix.com/products/python/pyOpenSSL/ ________________________________________________________________________ UPGRADING Before installing this version of pyOpenSSL, please make sure that you uninstall any previously installed pyOpenSSL version. Otherwise, you could end up not using the included OpenSSL libs. _______________________________________________________________________ SUPPORT Commercial support for these packages is available from eGenix.com. Please see http://www.egenix.com/services/support/ for details about our support offerings. _______________________________________________________________________ INFORMATION About Python (http://www.python.org/): Python is an object-oriented Open Source programming language which runs on all modern platforms.

Fabric 0.9 released
by Jeff Forcier 08 Nov '09

08 Nov '09

Hi all, I'd like to announce the release of Fabric 0.9! Quoting the README: Fabric is a Python library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks. It provides a basic suite of operations for executing local or remote shell commands (normally or via ``sudo``) and uploading/downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution. Fabric 0.9.0 is available on PyPI: http://pypi.python.org/pypi/Fabric/0.9.0 This 0.9 release marks a near-total rewrite from the previous Fabric release, version 0.1.x, with significant internal and external differences. It's more Pythonic, offers extra "contrib" functionality on top of the basic operations, and more besides. A list of major differences from the 0.1.x line can be found here: http://docs.fabfile.org/0.9.0/changes/0.9.html#major-changes The official webpage, including documentation and links to our ticket tracker, wiki, etc is now fabfile.org: http://fabfile.org/ http://docs.fabfile.org/ (currently, fabfile.org brings you here) http://code.fabfile.org/ http://wiki.fabfile.org/ Thanks, Jeff -- Jeff Forcier | http://bitprophet.org

ANN: PySiteCreator v0.1 released
by vasudevram 08 Nov '09

08 Nov '09

Hi, I've released a tool for creating HTML pages or Web sites by writing them in Python - PySiteCreator v0.1. Description of PySiteCreator: PySiteCreator is a tool that allows the user to create Web (HTML) sites by writing them entirely in Python. A user creates one or more Python source files in each of which they import a PySiteCreator helper module, and then call helper functions defined in that module, in order to emit HTML elements and associated content. They can then run the PySiteCreator program to process all those Python files; processing each Python file will result in the creation of a corresponding HTML file with the desired HTML elements and content. Some more details and the download link are available here on my blog: http://jugad2.blogspot.com/2009/11/early-release-of-pysitecreator-v01... I appreciate any feedback on PySiteCreator. Thanks, Vasudev Ram Biz: www.dancingbison.com Products: www.dancingbison.com/products.html Blog on software innovation: jugad2.blogspot.com xtopdf: fast and easy PDF creation from text PDFXMLRPC: client-server PDF creation from text over the Internet
