ABOUT
The eGenix.com mx Base Distribution for Python is a collection of
professional quality software tools which enhance Python's usability
in many important areas such as fast text searching, date/time
processing and high speed data types.
The tools have a proven track record of being portable across many
Unix and Windows platforms. You can write applications which use the
tools on Windows and then run them on Unix platforms without change
due to the consistent platform independent interfaces.
Contents of the distribution:
* mxDateTime - Easy to use Date/Time Library for Python
* mxTextTools - Fast Text Parsing and Processing Tools for Python
* mxProxy - Object Access Control for Python
* mxBeeBase - On-disk B+Tree Based Database Kit for Python
* mxURL - Flexible URL Data-Type for Python
* mxUID - Fast Universal Identifiers for Python
* mxStack - Fast and Memory-Efficient Stack Type for Python
* mxQueue - Fast and Memory-Efficient Queue Type for Python
* mxTools - Fast Everyday Helpers for Python
The package also includes the mxSetup module, which implements our
distutils based package tool chain (including the tooling for our
Python web installer technology), as well as a number of helpful
smaller modules in the mx.Misc subpackage, such as mx.Misc.ConfigFile
for config file parsing or mx.Misc.CommandLine to quickly write
command line applications in Python.
All available packages have proven their stability and usefulness in
many mission critical applications and various commercial settings all
around the world.

NEWS
The 3.2.9 release of the eGenix mx Base Distribution is the latest
release of our open-source Python extensions. It includes these fixes
and enhancements:
Fixes for all Python Builds
---------------------------
* Fixed the DateTime value range to only cover dates which can be
represented as broken down values. On 32-bit systems, the valid
range now is from -5879608-01-01 to 5879609-12-31, on 64-bit
systems from -25252734927766552-01-01 to
25252734927766553-12-31.Should be enough for most needs :-)
* Fixed the DateTimeDelta value range to only cover deltas which can
be represented as broken down values. On 32-bit systems, the valid
range now is from -2147483647:00:00:00.00 to
2147483647:00:00:00.00, on 64-bit systems from
-104249991374:07:36:32.00 to 104249991374:07:36:32.00.
* Fixed a segfault on Windows when using .strftime() on a DateTime
object with leap seconds. mxDateTime will now raise a ValueError
instead, since the Windows C runtime strftime() doesn't handle leap
seconds and segfaults.
* Fixed a segfault on Windows when using .strftime() with an
unsupported formatting code (e.g. %f). mxDateTime will now raise a
ValueError instead, since the Windows C runtime strftime() doesn't
like unsupported formatting codes or lone % at the end of the
format string and causes a segfault. Thanks to Barry B for
reporting this.
Fixes for Python Debug Builds
-----------------------------
* In this patch level release, we have significantly improved the
compatibility of eGenix mx Base with Python debug builds, which we
previously did not support. Regular Python builds are usually not
affected.
* Fixed crashes of several mx Base packages when using Python debug
builds, which were due to the use of free lists. Free lists are
disabled for Python debug builds now.
* Several mx Base packages crashed during interpreter shutdown when
using Python debug builds.
* mxBeeBase: Fixed a memory allocation error when using Python debug
builds.
* mxDateTime crashed when using Python debug builds due to the use of
free lists and a non-standard way of dealing with errors inside
object constructors, bypassing the logic used by debug builds to
trace object allocation. Thanks to Edson Tadeu M. Manoel for
bringing this to our attention.
* mxTools: Fix a segfault in napply() when using Python debug builds.
Installation Enhancements and Fixes (via included mxSetup)
----------------------------------------------------------
Most of these enhancements and fixes are part of the Python web
installer support we added to mxSetup a while ago. If you want to
learn more about this web installer technology, please see this talk
on the topic:
http://www.egenix.com/library/presentations/PyCon-UK-2014-Python-Web-Installer/
* Fixed traceback when building pure Python packages with mxSetup's
bdist_prebuilt.
* mxSetup's web installer now searches for "purepython" and "anyos"
tags as fallback when looking for OS dependent packages. It also
adds the "anyos" tag to all pure Python packages.
* Refactored the web installer in mxSetup into a class for easier
customization.
* Added --unicode-aware parameter support to bdist_egg when used with
setuptools.
* mxSetup now always produces PEP 440 compatible version numbers
(using mx_version()).
* Prebuilt archives created on Linux2 will now load fine on Linux3
machines. Same for FreeBSD and other systems which retain backwards
compatibility.
* Prebuilt archives will now also be usable on compatible platforms,
e.g. ones compiled on linux2 with linux3 systems and ones for
freebsd8 with freebsd9 or freebsd10.
* Fixed a bug in mxSetup which caused .pyc/.pyo not to get removed
when using 'pip uninstall'.
* 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.
* Added Raspberry Pi Ver. 2 support to mxSetup.
* Added support for bdist_wheels to allow building wheels from source
or from prebuilt packages using mxSetup.
* Removed a spurious AttributeError warning showing up when
installing egenix-mx-base prebuilt packages on Windows systems
without C compiler.
