From egenix-announcements at egenix.com Mon May 11 14:59:08 2015 From: egenix-announcements at egenix.com (egenix-announcements@egenix.com) Date: Mon May 11 13:59:15 2015 Subject: [eGenix.com] ANN: eGenix PyRun - One file Python Runtime 2.1.0 Message-ID: <5550998C.4070206@egenix.com> ________________________________________________________________________ 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.

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.
