ANN: eGenix pyOpenSSL Distribution 0.10.0-1.0.0a
by eGenix Team: M.-A. Lemburg June 10, 2010

June 10, 2010

________________________________________________________________________ ANNOUNCING eGenix.com pyOpenSSL Distribution Version 0.10.0-1.0.0a 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-0.10.0-1.0… ________________________________________________________________________ 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: https://launchpad.net/pyopenssl/ 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 pyOpenSSL version to 0.10.0 and the included OpenSSL version to 1.0.0a. Main new features in pyOpenSSL 0.10.0 (from the announcement) ------------------------------------------------------------- * pyOpenSSL 0.10 exposes several more OpenSSL APIs, including support for running TLS connections over in-memory BIOs, access to the OpenSSL random number generator, the ability to pass subject and issuer parameters when creating an X509Extension instance, more control over PKCS12 creation and an API for exporting PKCS12 objects, and APIs for controlling the client CA list servers send to clients. * Several bugs have also been fixed, including a crash when certain X509Extension instances are deallocated, a mis-handling of the OpenSSL error queue in the X509Name implementation, Windows build issues, and a possible double free when using a debug build. See Jean-Paul Calderone's full announcement for all details: https://launchpad.net/pyopenssl/+announcement/4318 New features in OpenSSL 1.0.0a since our last release ----------------------------------------------------- The main new features in OpenSSL 0.9.8m is the new support for RFC 5746, which addresses the SSL renegotiation problem found in earlier OpenSSL versions. * RFC 5746 - Transport Layer Security (TLS) Renegotiation Indication Extension: http://tools.ietf.org/html/rfc5746 * For a complete list of changes see: http://www.openssl.org/news/news.html Version 0.9.8n fixes this vulnerability (see http://www.openssl.org/news/secadv_20100324.txt): * "Record of death" vulnerability in OpenSSL 0.9.8f through 0.9.8m Version 1.0.0 adds many new features, including (see http://www.openssl.org/news/news.html): * Support for Whirlpool hash algorithm * Support for GOST cipher Version 1.0.0a fixes two security issues (see http://www.openssl.org/news/secadv_20100601.txt): * Invalid ASN1 module definition for CMS. * Invalid Return value check in pkey_rsa_verifyrecover New features in the eGenix pyOpenSSL Distribution ------------------------------------------------- * The embedded OpenSSL libs will now look for certificates in /etc/ssl on Unix platforms and /System/Library/OpenSSL on Mac OS X Note that it's usually better to explicitly tell OpenSSL where to look for trusted certificates via .load_verify_locations(None, certs_dir) than to rely on the above defaults using context.set_default_verify_paths() * Added support for Win64 and precompiled Python 2.6 compatible binaries for that platform (you can find the OpenSSL libs in openssl-win64/vc9) * Added support for Mac OS X 10.6 on Intel x64. * Added .egg Distributions for Python 2.4 as well (in order to support Plone 3). As always, we provide binaries that include both pyOpenSSL and the necessary OpenSSL libraries for all supported platforms: Windows x86 and x64, Linux x86 and x64, Mac OS X PPC, x86 and x64. Due to popular demand, we've also added .egg-file format versions of our eGenix.com pyOpenSSL Distribution for Windows, Linux and Mac OS X 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.

Hello All, This is the first release of Selenium 2 Python bindings. It contains the Selenium 1 Python bindings and a working Selenium 2 remote client. The plan in the future is to add Firefox, IE and Chrome "direct" bindings as well. Please note this is ALPHA quality code, so expect bugs (and report them at http://code.google.com/p/selenium/issues) Installing ========== pip install -U selenium Using ===== Server ------ You'll need the Selenium 2 server (Java). Download it from http://selenium.googlecode.com/files/selenium-server-standalone-2.0a4.jar The run the server with "java -jar selenium-server- standalone-2.0a4.jar" Example ------- from selenium.remote import connect from selenium import FIREFOX from selenium.common.exceptions import NoSuchElementException from time import sleep browser = connect(FIREFOX) # Get local session of firefox browser.get("http://www.yahoo.com") # Load page assert browser.get_title() == "Yahoo!" elem = browser.find_element_by_name("p") # Find the query box elem.send_keys("selenium\n") sleep(0.2) # Let the page load, will be added to the API try: browser.find_element_by_xpath("//a[contains(@href,'http:// seleniumhq.org')]") except NoSuchElementException: assert 0, "can't find seleniumhq" browser.close() Happy testing, -- Miki

ANN: unittest 0.4.2 released
by Michael Foord June 8, 2010

June 8, 2010

unittest2 0.4.2 is now released: http://pypi.python.org/pypi/unittest2/ unittest2 is a backport of the new features in the Python 2.7 version of the standard library testing framework unittest. The major improvements over unittest in Python 2.6 include: * A standard test runner with automatic test discovery * Improved command line options - fail fast, control-c catching and buffering standard out * Many new assert methods * Improvements to assertRaises (as context manager) and assertAlmostEqual (delta keyword argument) * Class and module level setup and teardown * Cleanup functions for better resource handling * Test skipping and expected failures * Lots of other minor changes and improvements For more details see: http://www.voidspace.org.uk/python/articles/unittest2.shtml Version 0.4.2 has feature parity with the version of unittest in Python 2.7 RC 1. There are a few bug fixes since version 0.4.1. 2010/06/06 - 0.4.2 ------------------ Improved help message for ``unit2 discover -h``. SkipTest in unittest.TestCase.setUpClass or setUpModule is now reported as a skip rather than an error. Excessively large diffs due to ``TestCase.assertSequenceEqual`` are no longer included in failure reports. (Controlled by ``TestCase.maxDiff``.) Matching files during test discovery is done in ``TestLoader._match_path``. This method can be overriden in subclasses to, for example, match on the full file path instead of the name only or use regular expressions for matching. Addition of a setuptools compatible entrypoint for the unit2 test runner script. Contributed by Chris Withers. Tests fixed to be compatible with Python 2.7, where deprecation warnings are silenced by default. Feature parity with unittest in Python 2.7 RC 1. All the best, Michael Foord -- http://www.ironpythoninaction.com/ http://www.voidspace.org.uk/blog
