eGenix.com mx Extension Series for Python
Full Source Python extensions providing important and useful
services for Python programmers.
WHAT IS IT ?
The eGenix.com mx Extensions for Python are a collection of
professional quality software tools which enhance Python's usability
in many important areas such as ODBC database connectivity, fast text
processing, date/time processing and web site programming.
Python is an open-oriented Open Source programming language which runs
on all modern platforms. By integrating ease-of-use, clarity in
coding, enterprise application connectivity and rapid application
design, Python establishes an ideal programming platform for todays IT
The tools have a proven record of being portable across many Unix and
Windows platforms, e.g. you can write applications which use an ODBC
database on Windows which then run on Unix platforms without change
due to the consistent platforms independent interfaces.
All available packages have proven their stability and usefulness in
many mission critical applications and various commercial settings all
around the world.
The two most well-known subpackages from the eGenix.com mx Extension
Series are mxDateTime and mxODBC providing date/time services and
professional ODBC database connectivity on practically all supported
Python platforms. These two packages enable database software which is
portable not only across platforms, but also across database backends.
WHAT'S NEW ?
mxODBC, mxDateTime and all other mx packages are now maintained by my
new company eGenix.com Software GmbH, Langenfeld in Germany
(http://www.egenix.com/). This move will provide a better base for
future development and also assures the availability of commercial
support, which is important for companies building applications based
on the eGenix.com mx Extensions.
The new versions of the eGenix.com mx Extensions use the Python 2.0
distutils packaging technology to simplify installation and use of the
many different subpackages. This is expected to greatly enhance the
installation and usage experience of the software.
In additions to many subpackage enhancements, this new release
repackages all mx Extensions under a new top-level package named
'mx'. This will allow you to use the subpackages side-by-side with
other Python tools using similar names.
The software is now delivered in two download archives: the eGenix.com
mx BASE package which holds all the Open Source tools from the series
and provides the basis for the other add-ons and the eGenix.com mx
COMMERCIAL package which currently only contains the mxODBC package.
The two packages are covered by the eGenix.com Public License and the
eGenix.com Commercial License respectively. Details about the licenses
can be found at:
theKompany.com has licensed the COMMERCIAL package (which includes
mxODBC) for inclusion in their brand new Qt-based Python IDE
BackAdder. It allows developing portable GUI-based database
applications which run on Windows and Linux platforms without any
change to the source code.
BlackAdder includes a 1 CPU license for this package at no extra cost,
so you may want to check out their great new product. See
EGENIX.COM MX BASE PACKAGE OVERVIEW:
mxDateTime - Generic Date/Time Types
mxDateTime is an extension package that provides three new object
types, DateTime, DateTimeDelta and RelativeDateTime, which let
you store and handle date/time values in a much more natural way
than by using ticks (seconds since 1.1.70 0:00 UTC; the encoding
used by the time module).
You can add, subtract and even multiply instances, pickle and
copy them and convert the results to strings, COM dates, ticks
and some other more esoteric values. In addition, there are
several convenient constructors and formatters at hand to greatly
simplify dealing with dates and times in real-world applications.
In addition to providing an easy-to-use Python interface the
package also exports a comfortable C API interface for other
extensions to build upon. This is especially interesting for
database applications which often have to deal with date/time
values (the mxODBC package is one example of an extension using
mxTextTools - Fast Text Processing Tools
mxTextTools is an extension package for Python that provides
several useful functions and types that implement
high-performance text manipulation and searching algorithms in
addition to a very flexible and extendable state machine, the
Tagging Engine, that allows scanning and processing text based on
low-level byte-code "programs" written using Python tuples. It
gives you access to the speed of C without the need to do any
compile and link steps every time you change the parsing
Applications include parsing structured text, finding and
extracting text (either exact or using translation tables) and
recombining strings to form new text.
mxStack - Fast and Memory-Efficient Stack Type
mxStack is an extension package that provides a new object type
called Stack. It works much like what you would expect from such
a type, having .push() and .pop() methods and focusses on
obtaining maximum speed at low memory costs.
mxTools - Collection of Additional Builtins
mxTools is an extension package that includes a collection of
handy functions and objects giving additional functionality in
form of new builtins to the Python programmer.
The package auto-installs the new functions and objects as
builtins upon first import. This means that they become
instantely available to all other modules without any further
action on your part. Add the line import NewBuiltins to your
site.py script and they will be available to all users at your
site as if they were installed in the Python interpreter itself.
mxProxy - Generic Proxy Wrapper Type
mxProxy is an extension package that provides a new type that is
suitable to implement Bastion like features without the need to
use restricted execution environments.
The type's main features are secure data encapsulation (the
hidden objects are not accessible from Python since they are
stored in internal C structures), customizable attribute lookup
methods and a cleanup protocol that helps in breaking circular
references prior to object deletion.
The latest version adds a very interesting new feature: weak
references which help you work with circular references in a way
that doesn't cause memory leakage in a Python system.
mxBeeBase - On-disk B+Tree Based Database Kit
mxBeeBase is a high performance construction kit for disk based
indexed databases. It offers components which you can plug
together to easily build your own custom mid-sized databases (the
current size limit is <CODE>sizeof(long)</CODE> which gives you
an address range of around 2GB on 32-bit platforms).
The two basic building blocks in mxBeeBase are storage and
index. Storage is implemented as variable record length data
storage with integrated data protection features, automatic data
recovery and locking for multi process access. Indexes use a high
performance optimized B+Tree implementation built on top of
Thomas Niemann's Cookbook B+Tree implementation
Note: mxBeeBase is new in this release and still in beta.
EGENIX.COM MX COMMERCIAL PACKAGE OVERVIEW:
mxODBC - Generic ODBC 2.0 interface
mxODBC is an extension package that provides a Python Database
API compliant interface to ODBC 2.0 capable database drivers and
In addition to the capabilities provided through the standard DB
API it also gives access to a rich set of catalog methods which
allow you to scan the database for tables, procedures,
etc. Furthermore, it uses the mxDateTime package for date/time
value interfacing eliminating most of the problems these types
normally introduce (other in/output formats are available too).
The latest version of the interface allows you to interface to
more than one database from one process. It includes a varity of
preconfigured setups for many commonly used databases such as
MySQL, Oracle, Informix, Solid and many more. A precompiled
version of the extension for use with the Windows ODBC manager is

WHAT DOES IT COST ?
The BASE packages come with a Python 2.0 style license, which means
that you can use them in both commercial and non-commercial settings
without fee or charge. All packages come with full source code.
mxODBC comes with a new licenses which allows non-commercial use
at no charge, but costs a moderate fee for commercial use. Please see
WHERE CAN I GET SUPPORT ?
Commercial quality support for these packages is available from
eGenix.com Software GmbH. Please see
