PyCA cryptography 0.9 released
by Paul Kehrer May 14, 2015

May 14, 2015

On behalf of all the contributors I am pleased to announce the release of PyCA/cryptography (https://github.com/pyca/cryptography) 0.9! Changelog: * Removed support for Python 3.2. This version of Python is rarely used and caused support headaches. Users affected by this should upgrade to 3.3+. * Deprecated support for Python 2.6. At the time there is no time table for actually dropping support, however we strongly encourage all users to upgrade their Python, as Python 2.6 no longer receives support from the Python core team. * Add support for the SECP256K1 elliptic curve. * Fixed compilation when using an OpenSSL which was compiled with the no-comp (OPENSSL_NO_COMP) option. * Support DER serialization of public keys using the public_bytes method of RSAPublicKeyWithSerialization, DSAPublicKeyWithSerialization, and EllipticCurvePublicKeyWithSerialization. * Support DER serialization of private keys using the private_bytes method of RSAPrivateKeyWithSerialization, DSAPrivateKeyWithSerialization, and EllipticCurvePrivateKeyWithSerialization. * Add support for parsing X.509 certificate signing requests (CSRs) with load_pem_x509_csr() and load_der_x509_csr(). * Moved cryptography.exceptions.InvalidToken to cryptography.hazmat.primitives.twofactor.InvalidToken and deprecated the old location. This was moved to minimize confusion between this exception and cryptography.fernet.InvalidToken. * Added support for X.509 extensions in Certificate objects. The following extensions are supported as of this release: - BasicConstraints - AuthorityKeyIdentifier - SubjectKeyIdentifier - KeyUsage - SubjectAlternativeName - ExtendedKeyUsage - CRLDistributionPoints - AuthorityInformationAccess - CertificatePolicies Note that unsupported extensions with the critical flag raise UnsupportedExtension while unsupported extensions set to non-critical are silently ignored. Read the X.509 documentation for more information. You can also view a more attractive version of the changelog here: https://cryptography.io/en/latest/changelog/ Master will be reopening for development of the tenth release shortly. -Paul Kehrer (reaperhulk)

new devpi-server/web/client/common: wheel testing, SHA256, ...
by holger krekel May 13, 2015

May 13, 2015

devpi-{server-2.2,web-2.3,client-2.2}: plugins, wheel support, pypi compat ============================================================================ With devpi-server-2.2, devpi-web-2.3, devpi-client-2.2 you'll get a host of fixes and improvements as well as some major new features for the private pypi system: - refined devpi-server plugin architecture based on "pluggy", the plugin and hook mechanism factored out from pytest. - devpi-client "test" now support testing of universal wheels IFF you have have an sdist alongside your wheel. python-specific wheels are not supported at this point. - devpi client "refresh NAME" allows to force a refresh of a pypi package from the command line. - internal refactorings to allow future pypi compatibility (for when it changes to SHA256 checksums). Also we use SHA256 checksumming ourselves now. For many more changes and fixes, please see the respective CHANGELOG of the respective packages. UPGRADE note: devpi-server-2.2 requires to ``--export`` your 2.1 server state and then using ``--import`` with the new version before you can serve your private packages through devpi-server-2.2. UPGRADE note: if you use ``updatetrigger_jenkins``, you have to install the devpi-jenkins plugin. You will get an error during import if you forget it. For docs and quickstart tutorials see http://doc.devpi.net many thanks to Florian Schulze who co-implemented many of the new features. And special thanks go to the two companies who funded major parts of the above work. have fun, holger krekel, merlinux GmbH

ANN: eGenix mxODBC Connect 2.1.3 - Remote Python Database Interface
by eGenix Team: M.-A. Lemburg May 13, 2015

May 13, 2015

________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Connect Remote Python Database Interface Version 2.1.3 mxODBC Connect is our commercially supported client-server product for connecting Python applications to relational databases in a truly platform independent way. This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-2.1.3-GA.html ________________________________________________________________________ INTRODUCTION The mxODBC Connect Database Interface for Python allows users to easily connect Python applications to all major databases on the market today in a highly portable, convenient and secure way. Python Database Connectivity the Easy Way ----------------------------------------- Unlike our mxODBC Python extension, mxODBC Connect is designed as client-server application, so you no longer need to find production quality database drivers for all the platforms you target with your Python application. Instead, you use an easy to install royalty-free Python client library which connects directly to the mxODBC Connect database server over the network. This makes mxODBC Connect a great basis for writing cross-platform multi-tier database applications and utilities in Python, especially if you run applications that need to communicate with databases such as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more, that run on Windows or Linux machines. Ideal for Database Driven Client Applications --------------------------------------------- By removing the need to install and configure ODBC drivers on the client side and dealing with complicated network setups for each set of drivers, mxODBC Connect greatly simplifies deployment of database driven client applications, while at the same time making the network communication between client and database server more efficient and more secure. For more information, please have a look at the mxODBC Connect product page, in particular, the full list of available features. For more information, please see the product page: http://www.egenix.com/products/python/mxODBCConnect/ ________________________________________________________________________ NEWS mxODBC Connect 2.1.3 is a patch level release of our successful mxODBC Connect database product. It includes these enhancements and fixes: Security Enhancements --------------------- * Updated included OpenSSL libraries to 1.0.1m. See https://www.openssl.org/news/secadv_20150319.txt for a complete list of changes. Among other security fixes, this addresses the FREAK Attack (CVE-2015-0204). * Upgraded default RSA key length for demo certificates to 2048 bits. mxODBC Connect Enhancements --------------------------- * Upgraded eGenix PyRun used for mxODBC Connect Server on Linux to 2.1.0. * Upgraded the Python version used for mxODBC Connect Server to 2.7.9. * Fixed a bug causing pip uninstall not to remove .pyc/.pyo files * Resolved an intermittent error related to hash seeds which sometimes caused prebuilt archives to not install correctly. Thanks to Albert-Jan Roskam for reporting this. mxODBC API Enhancements ----------------------- * Upgraded the mxODBC Connect Server to mxODBC 3.3.2: https://cms.egenix.com/company/news/eGenix-mxODBC-3.3.2-GA.html MS SQL Server ------------- * Fixed an "ODBC driver sent negative string size" error when using empty strings or None with output parameters for SQL Server ODBC drivers. * Clarified that due to the way the SQL Server ODBC driver sends data, mixing output parameters and output result sets is not possible. A work-around for this is to send back output parameters as additional result set. SAP Sybase ASE -------------- * Added a work-around for the Sybase ASE ODBC driver which has problems with BIGINT columns. These are now supported. * Fixed a possible "ODBC driver sent negative string size" error when using empty strings or None with output parameters for Sybase ASE ODBC drivers. Fixes ----- * Fixed the handling of None as default value for output parameters in e.g. stored procedures to use VARCHAR binding rather than CHAR binding. The latter caused padding with some database backends. * Changed cursor.colcount to be determined on-demand rather than right after the prepare step of statement execution. For the full set of changes, including those of the 2.1 series of mxODBC Connect, please check the mxODBC Connect change log: http://www.egenix.com/products/python/mxODBCConnect/changelog.html ________________________________________________________________________ UPGRADING You are encouraged to upgrade to this latest mxODBC Connect release. When upgrading, please always upgrade both the server and the client installations to the same version - even for patch level releases. We will give out 20% discount coupons for upgrade purchases going from mxODBC Connect Server 1.x to 2.1 and 50% coupons for upgrades from mxODBC Connect Server 2.x to 2.1.

tox-2.0.0: plugin support, platforms, env isolation
by holger krekel May 12, 2015

May 12, 2015

tox-2.0: plugins, platform, env isolation ========================================== tox-2.0 was released to pypi, a major new release with *mostly* backward-compatible enhancements and fixes: - experimental support for plugins, see https://testrun.org/tox/dev/plugins.html which includes also a refined internal registration mechanism for new testenv ini options. You can now ask tox which testenv ini parameters exist with ``tox --help-ini``. - ENV isolation: only pass through very few environment variables from the tox invocation to the test environments. This may break test runs that previously worked with tox-1.9 -- you need to either use the ``setenv`` or ``passenv`` ini variables to set appropriate environment variables. - PLATFORM support: you can set ``platform=REGEX`` in your testenv sections which lets tox skip the environment if the REGEX does not match ``sys.platform``. - tox now stops execution of test commands if the first of them fails unless you set ``ignore_errors=True``. Thanks to Volodymyr Vitvitski, Daniel Hahler, Marc Abramowitz, Anthon van der Neuth and others for contributions. More documentation about tox in general: http://tox.testrun.org/ Installation: pip install -U tox code hosting and issue tracking on bitbucket: https://bitbucket.org/hpk42/tox What is tox? ---------------- tox standardizes and automates tedious test activities driven from a simple ``tox.ini`` file, including: * creation and management of different virtualenv environments with different Python interpreters * packaging and installing your package into each of them * running your test tool of choice, be it nose, py.test or unittest2 or other tools such as "sphinx" doc checks * testing dev packages against each other without needing to upload to PyPI best, Holger Krekel, merlinux GmbH -- about me: http://holgerkrekel.net/about-me/ contracting: http://merlinux.eu 2.0.0 ----------- - (new) introduce environment variable isolation: tox now only passes the PATH and PIP_INDEX_URL variable from the tox invocation environment to the test environment and on Windows also ``SYSTEMROOT``, ``PATHEXT``, ``TEMP`` and ``TMP`` whereas on unix additionally ``TMPDIR`` is passed. If you need to pass through further environment variables you can use the new ``passenv`` setting, a space-separated list of environment variable names. Each name can make use of fnmatch-style glob patterns. All environment variables which exist in the tox-invocation environment will be copied to the test environment. - a new ``--help-ini`` option shows all possible testenv settings and their defaults. - (new) introduce a way to specify on which platform a testenvironment is to execute: the new per-venv "platform" setting allows to specify a regular expression which is matched against sys.platform. If platform is set and doesn't match the platform spec in the test environment the test environment is ignored, no setup or tests are attempted. - (new) add per-venv "ignore_errors" setting, which defaults to False. If ``True``, a non-zero exit code from one command will be ignored and further commands will be executed (which was the default behavior in tox < 2.0). If ``False`` (the default), then a non-zero exit code from one command will abort execution of commands for that environment. - show and store in json the version dependency information for each venv - remove the long-deprecated "distribute" option as it has no effect these days. - fix issue233: avoid hanging with tox-setuptools integration example. Thanks simonb. - fix issue120: allow substitution for the commands section. Thanks Volodymyr Vitvitski. - fix issue235: fix AttributeError with --installpkg. Thanks Volodymyr Vitvitski. - tox has now somewhat pep8 clean code, thanks to Volodymyr Vitvitski. - fix issue240: allow to specify empty argument list without it being rewritten to ".". Thanks Daniel Hahler. - introduce experimental (not much documented yet) plugin system based on pytest's externalized "pluggy" system. See tox/hookspecs.py for the current hooks. - introduce parser.add_testenv_attribute() to register an ini-variable for testenv sections. Can be used from plugins through the tox_add_option hook. - rename internal files -- tox offers no external API except for the experimental plugin hooks, use tox internals at your own risk. - DEPRECATE distshare in documentation

ANN: eGenix PyRun - One file Python Runtime 2.1.0
by eGenix Team: M.-A. Lemburg May 11, 2015

May 11, 2015

________________________________________________________________________ ANNOUNCING eGenix PyRun - One file Python Runtime Version 2.1.0 An easy-to-use single file relocatable Python run-time - available for Linux, Mac OS X and Unix platforms, with support for Python 2.6, 2.7 and **also for Python 3.4**. This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-PyRun-2.1.0-GA.html ________________________________________________________________________ INTRODUCTION eGenix PyRun is our open source, one file, no installation version of Python, making the distribution of a Python interpreter to run based scripts and applications to Unix based systems as simple as copying a single file. eGenix PyRun's executable only needs 11MB for Python 2 and 13MB for Python 3, but still supports most Python application and scripts - and it can be compressed to just 3-4MB using upx, if needed. Compared to a regular Python installation of typically 100MB on disk, eGenix PyRun is ideal for applications and scripts that need to be distributed to several target machines, client installations or customers. It makes "installing" Python on a Unix based system as simple as copying a single file. eGenix has been using eGenix PyRun internally in the mxODBC Connect Server product since 2008 with great success and decided to make it available as 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 major new release of eGenix PyRun 2.1 comes with the following new features and changes: New Features ------------ * Upgraded eGenix PyRun to work with and use Python 2.7.9 per default. * Upgraded eGenix PyRun to work with and use Python 3.4.3 for Python 3 support. * Added support for setting rpath on the PyRun binary to make it easy to ship external libraries together with PyRun, without having to set the LD_LIBRARY_PATH variable. * Added special support for egenix-pyopenssl to load its OpenSSL libs during startup. * PyRun allows to disable the new default HTTPS certificate verification (PEP 476) by setting the env var PYRUN_HTTPSVERIFY to 0. Default is to apply certificate verification. * Add support for more Python command line options: -s and -3 are ignored, -R raises an error explaining to use the PYTHONHASHSEED env var instead, -B prevents writing of byte code files.This should increase compatibility of PyRun with the standard Python command line interface. Enhancements / Changes ---------------------- * Added patch for Python 2.7.9 and 3.4.3 to make ctypes work again after changes to those versions of Python. See https://bugs.python.org/issue23042 for details. * The PyRun -v command line switch will now be passed to Python and supports setting the level using e.g. -vv for a verbose 2 level. * Disabled user site configurations in PyRun, since these are not needed or wanted for typical PyRun uses and cost startup time. * Optimized sys.path setup a bit. PyRun won't check for a Python build run and will not check lib/site-python on startup anymore. * PyRun for Python 3.4 is no longer compiled to always run in optimized mode. This allows using asserts in tests again. Fixes ----- * Entering "license" in the interactive shell now returns the correct URL for all supported Python versions. * Tilde expansion now works for most arguments of install-pyrun. This wasn't working before due to a bug. install-pyrun Quick Install Enhancements --------------------------------------------- eGenix PyRun includes a shell script called install-pyrun, which greatly simplifies installation of 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 This will automatically detect the platform, download and install the right pyrun version into targetdir. We have updated this script since the last release: * Updated install-pyrun to default to eGenix PyRun 2.1.0 and its feature set. * Added -r/--requirements option which allows automatically installing a set of required packages using a requirements file, so you can easily set up a complete Python environment using a single ./install-pyrun -r requirements.txt targetdir * Updated install-pyrun to install pyrun 2.1.0, setuptools 15.2 and pip 1.5.6 per default. For a complete list of changes, please see the eGenix PyRun Changelog: http://www.egenix.com/products/python/PyRun/changelog.html ________________________________________________________________________ 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. Source code archives are available for installation on other platforms, such as Solaris, AIX, HP-UX, etc. _______________________________________________________________________ SUPPORT Commercial support for this product is available from eGenix.com.

poliastro 0.3, Astrodynamics in Python
by Juan Luis Cano May 9, 2015

May 9, 2015

Hello all, I am very pleased to announce poliastro 0.3.0, a MIT licensed, pure Python library for studying Orbital Mechanics and Astrodynamics problems! https://poliastro.github.io/ This release features one major change and several new features: * Pure Python codebase: forget about Fortran thanks to numba! * Lambert problem solving * Planetary ephemerides computation thanks to jplephem You can install it using either pip or conda: $ pip install poliastro $ conda install poliastro --channel poliastro If you want to see an overview of poliastro capabilities, check out this IPython notebook describing how to plot the trajectory of rover Curiosity to Mars: http://nbviewer.ipython.org/github/poliastro/poliastro/blob/0.3.x/examples/… poliastro is an open source collection of Python subroutines for solving problems in Astrodynamics and Orbital Mechanics. It combines cutting edge technologies like Python JIT compiling (using numba) with young, well developed astronomy packages (like astropy and jplephem) to provide a user friendly API for solving Astrodynamics problems. It is therefore a experiment to mix the best Python open source practices with my love for Orbital Mechanics. The User Guide explains the basic use of the library and examples are provided in the form of IPython notebooks. See the "What's new" document and the GitHub log for a complete list of changes. https://poliastro.github.io/changelog.html#new-in-poliastro-0-3-0 The project is still a work in progress and the codebase is subject to change. Contributions, bug reports, suggestions and advice are more than welcome! https://github.com/poliastro/poliastro/issues Best regards, Juan Luis Cano
