From egenix-announcements at egenix.com Mon Sep 14 11:24:24 2015 From: egenix-announcements at egenix.com (egenix-announcements@egenix.com) Date: Mon Sep 14 10:24:38 2015 Subject: [eGenix.com] ANN: eGenix mxODBC Plone/Zope Database Adapter 2.2.3 Message-ID: <55F68438.80904@egenix.com> ________________________________________________________________________ ANNOUNCING mxODBC Plone/Zope Database Adapter Version 2.2.3 for the Plone CMS and Zope server platform Available for Plone 4.0-4.3 and Plone 5.0, Zope 2.12 and 2.13, on Windows, Linux, Mac OS X, FreeBSD and other platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Zope-DA-2.2.3-GA.html ________________________________________________________________________ INTRODUCTION The eGenix mxODBC Zope DA allows you to easily connect your Zope or Plone CMS installation to just about any database backend on the market today, giving you the reliability of the commercially supported eGenix product mxODBC and the flexibility of the ODBC standard as middle-tier architecture. The mxODBC Zope Database Adapter is highly portable, just like Zope itself, and provides a high performance interface to all your ODBC data sources, using a single well-supported interface on Windows, Linux, Mac OS X, FreeBSD and other platforms. This makes it ideal for deployment in ZEO Clusters and Zope hosting environments where stability and high performance are a top priority, establishing an excellent basis and scalable solution for your Plone CMS. Product page: http://www.egenix.com/products/zope/mxODBCZopeDA/ ________________________________________________________________________ NEWS The 2.2.3 release of our mxODBC Zope/Plone Database Adapter product is a patch level release of the popular ODBC database interface for Plone and Zope. It includes these enhancements and fixes: Feature Updates --------------- * We have integrated a new option to force serialized connects on a per Zope connection object basis. This can be used to work around bugs in ODBC drivers which are not fully thread-safe in the connect phase. The option is disabled per default. Driver Compatibility Enhancements --------------------------------- * ODBC driver compatibility updated. Upgraded to the latest mxODBC 3.3.5 release, adding compatibility enhancements for MS SQL Server. See the mxODBC 3.3.5 release announcements for full details. Installation Enhancements ------------------------- * Added pip install compatibility to mxODBC Zope DA by creating prebuilt archives and uploading a web installer to PyPI. This can be useful if you are installing Zope or Plone using a requirements.txt type approach, e.g. using pip install ThreadLock Products.ZSQLMethods egenix-mxodbc-zopeda * Enabled creating wheels from the prebuilt archives, which helps when running pip with the wheels package installed. pip then tries to build wheels during installation and caches them for future reuse. The complete list of changes is available on the mxODBC Zope DA changelog page. http://www.egenix.com/products/zope/mxODBCZopeDA/changelog.html mxODBC Zope DA 2.2.0 was released on 2014-12-11.

This announcement is also available on our website for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-2.1.4-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 ----------------------------------------- Building on our mxODBC database interface for Python, mxODBC Connect is designed as client-server application, so you no longer need to find production quality database drivers for all 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 2.1.4 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 1.0.1p. Please see the egenix-pyopenssl change log for a complete list of changes. Among other security fixes, this addresses the Logjam attack. http://www.egenix.com/products/python/pyOpenSSL/changelog.html mxODBC Connect Enhancements --------------------------- * Added support for the BinaryNull work-around added to mxODBC 3.3.5 in order to better support VARBINARY columns in MS SQL Server. Both mxODBC Connect Client and Server will need to upgraded to version 2.1.4 in order to be able to use the new singleton. * The mxODBC Connect Client can now be compiled to a wheel file to simplify deployment. Simply point the pip at the prebuilt archive. mxODBC API Enhancements ----------------------- * Upgraded the mxODBC Connect Server to mxODBC 3.3.5: http://www.egenix.com/company/news/eGenix-mxODBC-3.3.5-GA.html MS SQL Server ------------- * Documented and recommended use of SET NOCOUNT ON for running multiple statements or stored procedures. This can not only resolve issues with error reporting, it also results in better performance. * Added a work-around for MS SQL Server Native Client to be able to support VARCHAR/VARBINARY(MAX) columns when using the Native Client with direct execution mode or Python type binding mode. Thanks to ZeOmega for reporting this. * Added new helper singleton BinaryNull to allow binding a NULL to a VARBINARY column with SQL Server in direct execution mode or Python type binding mode (as used for FreeTDS). Using the usual None doesn't work in those cases, since SQL Server does not accept a VARCHAR data type as input for VARBINARY, except by using an explicit "CAST(? AS VARBINARY)". mxODBC binds None as VARCHAR for best compatibility, when not getting any type hints from the ODBC driver. * Added a fix for the MS SQL Server Native Client error "[Microsoft][ODBC Driver 11 for SQL Server][SQL Server]The data types varchar and text are incompatible in the equal to operator." when trying to bind a string of more than 256 bytes to a VARCHAR column while using cursor.executedirect(). cursor.execute() was unaffected by this. Thanks to Paul Perez for reporting this. * Added a note to avoid using "execute " when calling stored procedures with MS SQL Server. This can result in '[Microsoft][SQL Native Client]Invalid Descriptor Index' errors. Simply dropping the "execute " will have the error go away. * Added a work-around to address the FreeTDS driver error '[FreeTDS][SQL Server]The data types varbinary and image are incompatible in the equal to operator.' when trying to bind binary strings longer than 256 bytes to a VARBINARY column. This problem does not occur with the MS SQL Server Native Client. * Reenabled returning cursor.rowcount for FreeTDS >= 0.91. In previous versions, FreeTDS could return wrong data for .rowcount when using SELECTs.This should make SQLAlchemy users happy again. * Add work-around to have FreeTDS ODBC driver accept binary data in strings as input for VARBINARY columns. A side effect of this is that FreeTDS will now also accept binary data in VARCHAR columns. SAP Sybase ASE -------------- * Added work-arounds and improvements for Sybase ASE ODBC drivers to enable working with BINARY and VARBINARY columns. * Added a work-around for a cursor.rowcount problem with Sybase ASE's ODBC driver on 64-bit platforms. It sometimes returns 4294967295 instead of -1. * Added note about random segfault problems with the Sybase ASE 15.7 ODBC driver on Windows. Unfortunately, there's nothing much we can do about this, other than recommend using the Sybase ASE 15.5 ODBC driver version which does not have these stability problems. Fixes --------------------- * Added improved documentation on the direct execution model available in mxODBC. This can help in more complex parameter binding situations and also provides performance boosts for a few databases, including e.g. MS SQL Server.
