From python-url at phaseit.net Mon Jul 2 16:11:52 2007 From: python-url at phaseit.net (Cameron Laird) Date: Mon, 2 Jul 2007 14:11:52 +0000 (UTC) Subject: Python-URL! - weekly Python news and links (Jul 2) Message-ID: QOTW: "Modules are objects too - they're a good example of singletons. If you want to create a class containing only static methods: use a module instead. If you want to create a class having a single instance (a singleton), most of the time you can use a module instead. Functions don't *have* to be methods in a class, and the resulting design may still be a good design from an OO point of view." - Gabriel Genellina "I recommend gmane.org's NNTP server for all your mailing list needs." - Grant Edwards A "new mailing list has been started to discuss and get help with ... the Python/C api." http://groups.google.com/group/comp.lang.python/msg/aaa4787b320aea0a Ben Finney and others advertise the virtues of SQLAlchemy: http://groups.google.com/group/comp.lang.python/browse_thread/thread/31374383f59e321f/ IronPython Exception-handling involves a few new techniques: http://groups.google.com/group/comp.lang.python/msg/a2b697f8e4628dca Relative imports present a challenge for which there's no canonical solution.

Lemburg) Date: Mon, 02 Jul 2007 15:38:38 +0200 Subject: Interest in a one-day business conference for Python, Zope and Plone companies ? Message-ID: <4688FFDE.2020607@egenix.com> Hello, eGenix is looking into organizing a one day conference specifically for companies doing business with Python, Zope and Plone. The conference will likely be held in or close to D?sseldorf, Germany, which is lively medium-sized city, with good airport connections world-wide and specifically to all major European cities, so it's easy getting there and ideal for a one day event. The focus of the conference is on networking, meeting people, exchanging experience and exploring ways of working together. We are aiming at having a small conference program with just a few talks. The main intent of the presentations should be to initiate discussions among the attendees. Since this will be a business-only event, we will likely get professional help from a conference organizer and also try to sign up with a hotel to do all the catering, conference room maintenance, etc. My questions to you: * Would there be interest in such a conference event ? * How many people from your company would likely attend ? * Would a weekday or weekend conference date be more attractive ? * Does the focus suit your needs ? We will be giving a short presentation of what we have in mind at EuroPython 2007 in Vilnius in the context of the Open Space sessions: http://wiki.python.org/moin/EuroPython2007OpenSpace If you're interested, please contact us.

I believe it is fully functional, but I need help testing it so I can make it suitable for an enterprise environment. In this early phase, you can get Sprinkle as a development snapshot: sprinkle-2007-07-01. Asynchronous messaging is receiving renewed interest from developers. Let's give Python a simple, effective, and trusted messaging solution. The code is distributed under version 3 of the GPL, and runs on Unix- like platforms. Python 2.3.4 or later is required.

The new release is available from ftp.gnome.org and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.10/ Blurb: GTK+ is a toolkit for developing graphical applications that run on systems such as Linux, Windows and MacOS X. It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full features applications. What's new since 2.10.4 ? - Do access private GtkTooltip member tips_data_list, fixes build against Gtk+ 2.11.x (Johan) - Allow None to gtk_rc_get_style_by_paths (Mariano Suarez-Alvarez) - Fix defs file inconsistencies (Andrew Cowie) - Documentation build fixes (Richard Hult) - Code generator improvements (Tim Evans, Gustavo) - Include atk-types.defs when building using distutils, so gtk.Accessible is available on win32 PyGTK requires GTK+ >= 2.8.0 and Python >= 2.3.5 to build. Bug reports, as always, should go to Bugzilla; check out http://pygtk.org/developer.html and http://pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK. -- Johan Dahlin jdahlin at async.com.br From mmueller at python-academy.de Wed Jul 4 23:48:58 2007 From: mmueller at python-academy.de (Mike =?iso-8859-1?Q?M=FCller?=) Date: Wed, 04 Jul 2007 23:48:58 +0200 Subject: [ANN] Leipzig Python User Group - Meeting, July 10, 2007, 08:00pm Message-ID: <20070704214906.A4ABE72AE9D0@vs147134.vserver.de> === Leipzig Python User Group === We will meet on Tuesday, July 10 at 08:00pm at the training center of Python Academy in Leipzig, Germany ( http://www.python-academy.com/center/find.html ).

But most changes are in the itools.cms package: - The Quick Start is updated now, the "icms-make-package -t quickstart" command works again. - The new method "get_object" has been added to the itools.cms API. - An important bug has been fixed in the itools.cms database, where the incorrect usage of "mkstemp" made sometimes a transaction to fail because all files descriptors were used. - Now we correctly unindex the content of a folder when it is removed. - There are various fixes and improvements to the Calendar and Wiki objects. - The script "icms-update" has been improved in different ways. Most important, now it is possible to upgrade an itools.cms instance directly from 0.14 to 0.16 (no need to go through 0.15). Credits: - Herv? Cauwelier updated the Quick Start and fixed bugs; - Nicolas Deram worked on the Calendar object; - J.

It was preceeded by an alpha release in April. Since the beta we finished repackaging of eggs, added three new features and fixed more than 12 bugs, please see the change log for details. Zope 3.4 introduces support for binary large objects in the ZODB, provides a new postprocessing hook for publishing results and makes all Zope packages available as Python eggs. Development release and feedback -------------------------------- This is a development release with beta quality. It is intended for developers to check their applications for compatibility with the new features. This release *is not intended to be used in production environments*. We would love to hear about any bugs you encounter. Please use our bug tracker, the mailing lists, and the IRC channel to contact us in case you encounter any problems. This beta release will be succeeded by a release candidate which is expected to be available by August 5, 2007. For status updates on our roadmap check: https://launchpad.net/zope3/3.4/+milestones What is Zope 3? --------------- Zope 3 is a web application server that continues to build on the heritage of Zope. It was rewritten from scratch based on the latest software design patterns and the experiences of Zope 2. The component architecture is the very core of Zope 3 that allows developers to create flexible and powerful web applications. Compatibility with Zope 2 -------------------------- We continue to work on the transition from Zope 2 to Zope 3 by making Zope 2 use more and more of the Zope 3 packages. But we're not there yet. **You can't run Zope 2 applications in Zope 3.** Downloads --------- Zope 3 can be downloaded from: http://zope.org/Products/Zope3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt file of the distribution. The binary installer is recommended for Windows. Zope 3.4 requires Python 2.4.3 to run. You must also have zlib installed on your system.

Message-ID: pypar 2.0alpha released on sourceforge. Pypar is a simple and efficient MPI binding for Python Copyright (C) 2001-2007 Ole M. Nielsen ------------------------------------------------------- This is to announce an upgrade of pypar, ver 2.0 alpha - a simple and efficient Python binding to MPI for parallel programming using Python. Version 1.0 was announced on this mailing list on 7th of February 2002 http://mail.python.org/pipermail/python-announce-list/2002-February/001228.html. Pypar has been used in many projects over the years but it became clear that relying on the Numeric was becoming a liability and many developers requested an upgrade to numpy. The update to version 2.0alpha signifies 1: Porting pypar to numpy instead of the discontinued Numeric module 2: Moving pypar to sourceforge: http://sourceforge.net/projects/pypar/ 3: Numerous improvements and optimisations added over the past years Version 2.0alpha has been tested on a few platforms, but I haven't been able to verify that it installs everywhere. The purpose of this post is to encourage existing and new users of pypar to try the new release and to get back to me with questions, feedback and patches that will allow pypar to run on as many platforms as possible. I am looking forward to hear from you Ole M. Nielsen Canberra, Australia Ole.Moller.Nielsen at gmail.com Background: ----------- The use of multi processor computers is becoming increasingly common and they appear in many forms: Desktop computers with more than one processor sharing memory, clusters of PC's connected with fast networks known as Beowulf clusters, and high-end super computers all make use of parallelism. Even playstations have been connected to form computational networks (http://arrakis.ncsa.uiuc.edu/ps2/cluster.php). To efficiently use these machines in a portable way one must be able to control communication among programs running in parallel. One such standard is the Message Passing Interface (MPI) for inter-processor communication. Python and MPI: --------------- There are a number of other Python bindings to MPI that are more comprehensive than pypar (PyMPI, Scientific Python). However, pypar stands out by not requiring the Python interpreter to be modified, by being very easy to install and by by shielding the user from many details involving data types and MPI parameters without sacrificing the full bandwidth provided by the underlying MPI implementation. Download: --------- Pypar can be downloaded from http://sourceforge.net/projects/pypar Credentials: ------------ Pypar was developed by Ole Nielsen at the Australian National University in 2001 for use in the APAC Data Mining Expertise Program and has been published under the GNU Public License (http://www.gnu.org/licenses/gpl.txt) Contact: Ole.Moller.Nielsen at gmail.com

Ophelia creates XHTML pages from templates written in TAL, the Zope Tag Attribute Language. It is designed to reduce code repetition to zero. The package contains both a WSGI application running Ophelia as well as a request handler for mod_python, the Python module for the Apache2 web server. Additionally, a script is included that renders a page and dumps it to stdout, and another one that runs a wsgiref based HTTP server hosting Ophelia's WSGI application. Ophelia is released under the Zope Public License, version 2.1. To use Ophelia 0.3, you need Python 2.4. The mod_python request handler requires mod_python 3.3 or better. The package is available from the Python package index as a source distribution and a Python 2.4 egg: The source code contains a zc.buildout configuration for an environment including Apache and mod_python. You can access the source code repository at , browse it using ViewCVS at , or visit Ophelia's web page, containing a commented live usage example, at . >From the documentation: What kind of sites is Ophelia good for? ======================================= Static content -------------- Consider Ophelia as SSI on drugs. It's not fundamentally different, just a lot friendlier and more capable. Use Ophelia for sites where you basically write your HTML yourself, except that you need write the recurring stuff only once. Reducing repetition to zero comes at a price: your site must follow a pattern for Ophelia to combine your templates the right way. Consider your site's layout to be hierarchical: there's a common look to all your pages, sections have certain characteristics, and each page has unique content. It's crucial to Ophelia that this hierarchy reflect in the file system organization of your documents; how templates combine is deduced from their places in the hierarchy of directories. Dynamic content --------------- Ophelia makes the Python language available for including dynamic content. Each template file may include a Python script. Python scripts and templates contributing to a page share a common set of variables to modify and use. Ophelia's content model is very simple and works best if each content object you publish is its own view: the page it is represented on. If you get content from external resources anyway (e.g. a database or a version control repository), it's still OK to use Ophelia even with multiple views per content object as long as an object's views don't depend on the object's type or even the object itself. Trying to use Ophelia on a more complex site will lead to an ugly entanglement of logic and presentation. Don't use Ophelia for sites that are actually web interfaces to applications, content management systems and the like. -- Viele Gr??e, Thomas From cito at online.de Sat Jul 7 23:13:22 2007 From: cito at online.de (Christoph Zwerschke) Date: Sat, 07 Jul 2007 23:13:22 +0200 Subject: ANN: Webware and DBUtils 0.9.4 released Message-ID: <469001F2.3050603@online.de> Webware 0.9.4 and DBUtils 0.9.4 have been released.

It is available at http://code.google.com/p/crunchy What is Crunchy? Crunchy is a an application that transforms html Python tutorials into interactive session viewed within a browser. We are not aware of any other application (in any language) similar to Crunchy. Currently Crunchy has only been fully tested with Firefox; we know that some browsers simply don't work with it. Crunchy should work with all operating systems - it has been tested fairly extensively on Linux, Windows and Mac OS. What is new in this release? Crunchy has been rewritten from scratch from the previous version (0.8.2), to use a custom plugin architecture. This makes easier to extend and add new functionality. Rather than list the differences with the old release, it is easier to list the essential features of this new version. 1. Crunchy can work best with specially marked-up html tutorials. However, it can now work with any html tutorials - including the official Python tutorial on the python.org site. Html pages can be loaded locally or remotely from anywhere on the Internet. Crunchy uses a combination of Elementtree and BeautifulSoup to process html pages. Non W3C-compliant pages can be handled, but the visual appearance is not guaranteed to reproduce that normally seen using a browser. 2. Crunchy can insert a number of Python interpreters inside a web page. In the default mode, it does that whenever it encounters an html 

 element which is assumed to contain some Python code.
These interpreters can either share a common environment (e.g. modules
imported in one of them are known in the other) or be isolated one
from another.

3. Crunchy adds automatic css styling to the Python code -  you can
look at the official Python tutorial using your browser (all Python
code in blue) and compare with what Crunchy displays to give you a
good idea.

4. Instead of inserting an interpreter, Crunchy can insert a code
editor that can be used to modify the Python code on the page and
execute it.  The editor can be toggled to become a fairly decent
syntax aware editor that can save and load files.

5. Crunchy has a "doctest" feature where the code inside the 
 is
taken to be the result
of an interpreter session and the user has to write the code so as to
make the interpreter session valid; this is useful in a teaching
environment. Messages from the Crunchy's doctest are "friendlier" for
Python beginners than the usual tracebacks.

6. Crunchy has a small graphics library that can be imported, either
inside an editor or an interpreter, to produce simple graphics (even
animations!) inside the browser.

7. For the user that needs better quality graphics, Crunchy supports
programs (such as matplotlib) that can create image files; by
executing the code, the image produced is loaded inside the browser
window.  In this capacity, Crunchy could be used as a front end for
libraries such as matplotlib.

8. Crunchy supports code execution of files as separate processes,
making it suitable to launch gui based application from the browser
window.

9. Crunchy's interpreter has an interactive "help" feature like many
python-aware IDEs.

10. Crunchy includes a fairly comprehensive tutorial on its own use,
as well as a reference for tutorial writers that want to make their
tutorials "crunchy-friendlier".

11. As a security feature, crunchy strips all pre-existing javascript
code from an html page before displaying it inside the browser window.

Bug reports, comments and suggestions are always welcome.

Andr? Roberge, for the Crunchy team.

Subject: PyGTK Introduction @ Toronto Area Python User's Group Meeting next
	Tuesday
Message-ID: <4693D53C.7090807@vrplumber.com>

Our topic for the next PyGTA meeting is the PyGTK binding to the Open 
Source GTK+ GUI library.  Myles Braithwaite, a local developer and 
consultant will be presenting an introduction to the library including 
how to get started programming with it.  Myles has used GTK, among other 
things, to develop a pair of games for the OLPC laptop.  GTK is 
reasonably portable Free software that has a number of GUI-layout tools, 
with the Glade system being the most well-known among them.

We'll be meeting at our regular venue, Linux Caffe, which is open until 
11pm for the summer, affording us a much more relaxed pace for our 
meetings.  We'll plan to start the presentation for 7:15pm, with people 
encouraged to gather at 7:00 to chat and socialise.  Linux Caffe is at 
the corner of Grace and Harbord streets, 1 block South of Christie 
station.  Free WiFi is available, as are snacks and sandwiches, ice 
cream, smoothies, coffee, tea and the like.

Details on how to get to Linux Caffe are available on the PyGTA 
next-meeting page:

Message-ID: <1184129696.072448.266240@z28g2000prd.googlegroups.com>

This one does not need you to set any breakpoints. It records the
entire run. Handy, if you don't know where to start.

Run the program once and after that all the runtime data is available
to you. Which means you can jump to any point in the run and verify
the code against runtime data.

The user interface is the python code itself viewed inside a Firefox
browser.
Scroll to a line you're interested in and click the variable.

It requires Firefox and Python 2.5.

Subject: bbfreeze 0.95.1
Message-ID: <932f8baf0707110222s5b16f0d9ifbe4ff8fbbcc93fd@mail.gmail.com>

Hi all,

I've just uploaded bbfreeze 0.95.1 to python's cheeseshop.
bbfreeze creates standalone executables from python scripts. It's similar
in functionality to py2exe or cx_Freeze.

This release fixes some problems with egg files and with some of the
recipes.

*NEW* support for egg files: bbfreeze scans zipped egg files and now
  includes whole egg files/directories in the distribution. Programs
  using setuptools' pkg_resources module will now work.

It offers the following features:

easy installation
  bbfreeze can be installed with setuptools' easy_install command.

zip/egg file import tracking
  bbfreeze tracks imports from zip files.

multiple script freezing
  bbfreeze can freeze multiple scripts at once.

python interpreter included
   bbfreeze will create an extra executable named 'py', which might be
  used like the python executable itself.

bbfreeze works on windows and UNIX-like operating systems. It
currently does not work on OS X. bbfreeze has been tested with python
2.4 and 2.5. bbfreeze will not work with python versions prior to 2.3
as it uses the zipimport feature introduced with python 2.3.

Subject: itools 0.16.2 released
Message-ID: <4695F5D2.3000006@itaapy.com>

itools is a Python library, it groups a number of packages into a single
meta-package for easier development and deployment:

   itools.catalog        itools.i18n             itools.tmx
   itools.cms            itools.ical             itools.uri
   itools.csv            itools.odf              itools.vfs
   itools.datatypes      itools.pdf              itools.web
   itools.gettext        itools.rest             itools.workflow
   itools.handlers       itools.rss              itools.xhtml
   itools.html           itools.schemas          itools.xliff
   itools.http           itools.stl              itools.xml

The big news in this release is the License upgrade; now itools is
available under the terms and conditions of the GPL version 3.  Check
the LICENSE.txt file.

Also, a bunch of bugs have been fixed.  Some of them have triggered
small backwards incompatible changes; check the UPGRADE-0.16.2 file for
the details.

The package that has changed the most is "itools.stl":

  - Now STL returns by default the stream of events, not the serialized
    byte string. The new parameter "mode" replaces the boolean parameter
    "html", it has four modes: 'events' (default), 'xml', 'xhtml' and
    'html'.

  - Now it is possible to insert a sequence of XML events into "${...}"
    expressions.

  - New public function "set_prefix" that rewrites the relative URLs of
    the given XML events.  Its prototype is "stl(events, prefix)".

  - The main function "stl" accepts a generator or a "Parser" instance
    for the "events" parameter (not only a list).  It also accepts a byte
    string for the "prefix" parameter (not only a "Path" instance).

  - Fix when "stl:repeat" and "stl:if" expressions are together in the
    same element.

Other changes worth to mention are:

  - Reorganize the RELEASE and UPDATE files.  The old ones are kept on
    the "doc" folder.

  - [itools.catalog] Fix "catalog.search()", without parameters it
    returns all indexed documents.

  - [itools.cms] Various minor fixes for the user interface (Wiki, web
    pages view, search form, folder's browse view, login form, user's
    edit account form and CSS).

  - [itools.handlers] Fix "has_handler(path)" for special paths, like
    "has_handler('.')".

  - [itools.i18n] Rewrite the accept module.  Much simpler, now language
    negotiation behaves as defined by RFC2616.  And "accept" objects are
    correctly serialized.

  - [itools.pdf] Various RML fixes.

  - [itools.web] The new method "context.get_accept_language" replaces
    "context.request.accept_language"

  - [itools.xhtml] Escape the text nodes when serializing to HTML.

Hi all,

I've just uploaded bbfreeze 0.95.2 to python's cheeseshop.
bbfreeze creates standalone executables from python scripts. It's similar
in functionality to py2exe or cx_Freeze.

This release fixes issues with python installation, where the zlib module is

called zlibmodule.so (e.g. fedora core 7). If you previously got
"zipimport.ZipImportError: can't decompress data; zlib not available" when
trying to run the frozen executables, try version 0.95.2.


*NEW* support for egg files: bbfreeze scans zipped egg files and now
  includes whole egg files/directories in the distribution. Programs
  using setuptools' pkg_resources module will now work.

It offers the following features:

easy installation
  bbfreeze can be installed with setuptools' easy_install command.

zip/egg file import tracking
  bbfreeze tracks imports from zip files.

multiple script freezing
  bbfreeze can freeze multiple scripts at once.

python interpreter included
   bbfreeze will create an extra executable named 'py', which might be
  used like the python executable itself.

bbfreeze works on windows and UNIX-like operating systems. It
currently does not work on OS X. bbfreeze has been tested with python
2.4 and 2.5. bbfreeze will not work with python versions prior to 2.3
as it uses the zipimport feature introduced with python 2.3.

Message-ID: <200707131337.15680.faltet@carabos.com>

===========================
 Announcing PyTables Pro 2.0
===========================

PyTables Pro is a library for managing hierarchical datasets and
designed to efficiently cope with extremely large amounts of data with
support for full 64-bit file addressing.  PyTables Pro runs on top of
the HDF5 library and NumPy package for achieving maximum throughput and
convenient use.  The main difference between PyTables Pro and regular
PyTables is that the Pro version includes OPSI, a new indexing
technology, allowing to perform data lookups in tables exceeding 10
gigarows (10**10 rows) in less than 1 tenth of a second.

After more than two years of continuous development and about five
months of exhaustive testing and benchmarking, we are very happy to
announce that PyTables Pro 2.0 (final) is here.  Wearing more than 15000
tests and having passed the complete test suite in the most common
platforms (Windows, Mac OS X, Linux 32-bit and Linux 64-bit), we are
pretty confident that PyTables Pro 2.0 is ready to be used in production
scenarios, bringing maximum stability and top performance to those users
who need it.  For more info about PyTables Pro, see:
http://www.carabos.com/products/pytables-pro

As already said, PyTables Pro includes, as its most distinguishing
feature, the powerful OPSI technology that allows to index very large
amounts of data very rapidly while allowing first-class query response
times.  Its operational details as well as exhaustive benchmarks are
explained with full detail in the OPSI white paper:
http://www.carabos.com/docs/OPSI-indexes.pdf

You can buy PyTables Pro at the Carabos shop:
http://www.carabos.com/buy

Coinciding with the publication of PyTables Pro we are introducing an
innovative liberation process that will allow to ultimate release the
PyTables Pro 2.x series as open source.  You may want to know that, by
buying a PyTables Pro license, you are contributing to this process. For
details, see: http://www.carabos.com/liberation


Migration Notes
===============

If you are a user of PyTables 1.x, probably it is worth for you to look
at ``MIGRATING_TO_2.x.txt`` file where you will find directions on how
to migrate your existing PyTables 1.x apps to the 2.x versions.  You can

Keep reading for an overview of the most prominent improvements in
PyTables 2.0 series.


New features of PyTables 2.0
============================

- A complete refactoring of many, many modules in PyTables.  With this,
  the different parts of the code are much better integrated and code
  redundancy is kept under a minimum.  A lot of new optimizations have
  been included as well, making working with it a smoother experience
  than ever before.

- NumPy is finally at the core!  That means that PyTables no longer
  needs numarray in order to operate, although it continues to be
  supported (as well as Numeric).  This also means that you should be
  able to run PyTables in scenarios combining Python 2.5 and 64-bit
  platforms (these are a source of problems with numarray/Numeric
  because they don't support this combination as of this writing).

- Most of the operations in PyTables have experimented noticeable
  speed-ups (sometimes up to 2x, like in regular Python table
  selections).  This is a consequence of both using NumPy internally and
  a considerable effort in terms of refactorization and optimization of
  the new code.

- Combined conditions are finally supported for in-kernel selections.
  So, now it is possible to perform complex selections like::

      result = [ row['var3'] for row in
                 table.where('(var2 < 20) | (var1 == "sas")') ]

  or::

      complex_cond = '((%s <= col5) & (col2 <= %s)) ' \
                     '| (sqrt(col1 + 3.1*col2 + col3*col4) > 3)'
      result = [ row['var3'] for row in
                 table.where(complex_cond % (inf, sup)) ]

  and run them at full C-speed (or perhaps more, due to the cache-tuned
  computing kernel of Numexpr, which has been integrated into PyTables).

- Now, it is possible to get fields of the ``Row`` iterator by
  specifying their position, or even ranges of positions (extended
  slicing is supported).  For example, you can do::

      result = [ row[4] for row in table    # fetch field #4
                 if row[1] < 20 ]
      result = [ row[:] for row in table    # fetch all fields
                 if row['var2'] < 20 ]
      result = [ row[1::2] for row in       # fetch odd fields
                 table.iterrows(2, 3000, 3) ]

  in addition to the classical::

      result = [row['var3'] for row in table.where('var2 < 20')]

- ``Row`` has received a new method called ``fetch_all_fields()`` in
  order to easily retrieve all the fields of a row in situations like::

      [row.fetch_all_fields() for row in table.where('column1 < 0.3')]

  The difference between ``row[:]`` and ``row.fetch_all_fields()`` is
  that the former will return all the fields as a tuple, while the
  latter will return the fields in a NumPy void type and should be
  faster.  Choose whatever fits better to your needs.

- Now, all data that is read from disk is converted, if necessary, to
  the native byteorder of the hosting machine (before, this only
  happened with ``Table`` objects).  This should help to accelerate
  applications that have to do computations with data generated in
  platforms with a byteorder different than the user machine.

- The modification of values in ``*Array`` objects (through __setitem__)
  now doesn't make a copy of the value in the case that the shape of the
  value passed is the same as the slice to be overwritten. This results
  in considerable memory savings when you are modifying disk objects
  with big array values.

- All leaf constructors (except for ``Array``) have received a new
  ``chunkshape`` argument that lets the user explicitly select the
  chunksizes for the underlying HDF5 datasets (only for advanced users).

- All leaf constructors have received a new parameter called
  ``byteorder`` that lets the user specify the byteorder of their data
  *on disk*.  This effectively allows to create datasets in other
  byteorders than the native platform.

- Native HDF5 datasets with ``H5T_ARRAY`` datatypes are fully supported
  for reading now.

- The test suites for the different packages are installed now, so you
  don't need a copy of the PyTables sources to run the tests.  Besides,
  you can run the test suite from the Python console by using::

  >>> tables.tests()

SkipoleMonitor is available at http://code.google.com/p/skipole-monitor/

Version 0.4 now released.
What is SkipoleMonitor?
=================

SkipoleMonitor is a free network monitor for Windows and Linux. On running
the program, a GUI window appears, and hosts can be added, which Skipole
Monitor will regularly ping, showing the results via a built-in Web server.
Hosts can be grouped, so the Web server will show group symbols that the
viewer can open to inspect the hosts, or further sub-groups, within.As hosts
(and groups of hosts) change status, SkipoleMonitor can be set to send email
and syslog alerts.

Written in Python, and uses the wxPython library, it has been tested on
Windows and Linux.

http://tools.assembla.com/yolk

July 16, 2007 - 0.3.0 Release


Changes:
--------

Added -L and -C options for Cheese Shop's new XML-RPC methods
'changelog' and 'release_updates'
Added -F option to fetch source, egg or do a subversion checkout
Added 'svn' option for -T
Better package name list cache handling


What is yolk?
-------------

Yolk is a command-line tool for querying The Cheese Shop and your
installed Python packages.
Yolk is in the early stages of development but you may find it useful.


Some Features
-------------

 * Show which installed packages have newer versions available by querying PyPI
 * List Python packages installed by distutils, setuptools, or easy_install
 * Determine which packages are activated or not (--multi-version)
 * Determine which packages are deployed in development mode
 * Examine package metadata
 * Show dependencies of packages installed by setuptools, if available
 * Query PyPI for various package information using XML-RPC interface
 * Examine entry maps and entry points for setuptools deployed Python packages
 * Determine download URL or subversion checkout URL of a package
 * Easily download source, egg or do a subversion checkout by simply
giving the package name
 * Check latest releases on The Cheese Shop or detailed Cheese Shop ChangeLog
 * Determine which pkgs were installed by distutils/setuptools or your
package manager (Gentoo only so far)
 * And if none of that interests you, a little Red Leicester then, perhaps?

Note:
-----

With Python<=2.3 yolk only lists installed packages if the setup.py
uses setuptools or if the package was installed via easy_install.
Users of Python>=2.5 get the whole enchillada.


Where can I get it?
-------------------

'easy_install -U yolk'

http://cheeseshop.python.org/packages/source/y/yolk/yolk-0.3.0.tar.gz
http://cheeseshop.python.org/packages/2.5/y/yolk/yolk-0.3.0-py2.5.egg

yolk is available in Gentoo's portage system as 'dev-python/yolk'

Message-ID: <2564182.FvFa657ivK@snoopy.mio>

IMDbPY 3.1 is available (tgz, deb, rpm, exe) from:
  http://imdbpy.sourceforge.net/

IMDbPY is a Python package useful to retrieve and manage the data of
the IMDb movie database about both movies and people.

In this release there are many fixes to stay up-to-date with the new
IMDb's layout. Moreover there is support for the new 'synopsis' and
'parents guide' pages.

Platform-independent and written in pure Python (and few C lines), it
can retrieve data from both the IMDb's web server and a local copy of
the whole database.

IMDbPY package can be very easily used by programmers and developers
to provide access to the IMDb's data to their programs.
Some simple example scripts are included in the package; other
IMDbPY-based programs are available from the home page.

Subject: Publication of Hachoir project version 1.0
Message-ID: <1184807465.743228.278690@i38g2000prf.googlegroups.com>

Hachoir is a framework for binary file manipulation: file format
recognition, metadata extraction, search files in any binary stream
(forensics), view file content with human representation, etc. It's
composed of many component:

 Programs:
 * hachoir-metadata: fault tolerant metadata extraction;
 * hachoir-subfile: search subfiles in a disk image or any other
binary
   stream;
 * hachoir-urwid, hachoir-wx, hachoir-gtk, hachoir-gtk: user interface
to
   view file content (curses, wxPython, pygtk, web+ajax);

 Modules:
 * hachoir-core: library to split binary data into a field tree;
 * hachoir-parser: collection of 70 file format parsers;
 * hachoir-regex: regular expression optimization/manipulation and
pattern
   matching (used by hachoir-subfile).


Project website:
  http://hachoir.org/

List of supported file formats:
  http://hachoir.org/wiki/hachoir-parser#Listofparsers
  (jpeg, ttf, exe, rar, ogg, ntfs, ole2, torrent, ...)

Examples of metadata extraction:
  http://hachoir.org/wiki/hachoir-metadata/examples

hachoir-wx screenshots:
  http://hachoir.org/wiki/hachoir-wx#Screenshots


Hachoir works any operating system and only depends on Python (2.4+).
Packages are available for Debian, Mandriva, Gentoo, Arch and FreeBSD.

hachoir-core goal is to ease binary parser writing. It takes care of
endian
problem, has bit resolution (for addresses and sizes), and only use
Unicode
charset for text. It gives a nice API to the programmer (see parsers
source
code): each field is an object. A parser is lazy: its value, display
string,
description, etc. is computed on demand (when the program ask it). So
it's
possible to parse very complex structures and huge files (60 GB or
more is
not a problem).

hachoir-core and hachoir-metadata are "fault tolerant": on parser/
extractor
error or file error (truncated or damaged file), the program doesn't
stop
but continue to next valid state. It allows to extract informations on
very
damaged files.

hachoir-metadata create a dictionary with typed values: track number
is an
integer, creation date is datetime.datetime object, etc. and all text
are
stored as Unicode string. The API allows easy reuse of extracted data.

Source code has good code coverage with automatic tests (lot of
testcases).
Fuzzing is sometimes used to find more bugs.

Some experimental programs exist like hachoir-strip: program to remove
personal information (author name, timestamp, copyright, etc.) from a
picture, movie, sound, archive, etc. Another example: swf_extract.py
allows
to extract pictures and sounds from a SWF (Flash) document.

I've been getting ready for OSCon 2007 next week, and theres quite a bit
of Python related activity there.

Based on a suggestion from Jeff Rush, (who can't be there), I've
proposed a Python Advocacy BoF on Monday, from 6:30pm - 7:30pm. For
anyone arriving early, this will be a great opportunity to coordinate
Python advocacy activites at OSCon.

Theres also a regular Python BoF on Wednesday from 8:30pm - 9:30pm.

Apart from those, I've tagged [1] a bunch of sessions I felt were Python
related. This list includes sessions outside the main Python track.

Subject: dbcook 0.1
Message-ID: <200707191212.59114.sqlalchemy@googlegroups.com>

g'day.

This is dbcook, a framework to cook databases from recipes, written 
as python declarations. Eventually the result may be edible (;-)

If u're interested, have a look, dbcook/usage/example1.py might be a 
start. The directory-structure is still in flux - u need to get the 
internal dbcook/ accessible somehow (PYTHONPATH or else). Licensed as 
MIT-license.

svn co https://dbcook.svn.sf.net/svnroot/dbcook/trunk

http://dbcook.sf.net


Here a short description what it probably is, and can do:

A framework for declarative mapping of object hierarchies/relations 
into a (relational or not) database.

The "language" itself is made with independence in mind, although 
currently all available builder stuff is over SQLAlchemy as backend 
(so it looks like wrapping declarative translator).

It completely hides/automates the table/key/column/mapper/whatever 
creation. The user can only control certain characteristics of the 
way the mapping happens, mostly related to hierarchy and relations 
between objects (subclasses, instances, leafs, uniqueness etc).

it's about 10 months old now. It can handle: 
 - data column types
 - reference columns -> foreign keys
 - class inheritance, and class inclusion (inheritance without 
    database mapping of the base), and virtual classes (those never
    have instances). More in mapcontext._Base
 - polymorphism, giving 3 kinds of queries for each mapped class: ALL, 
    base-only, subclasses only
 - any combination of table-inheritance-types within the tree 
    (concrete/joined/no-single-yet; beware that sql-polymorphism only 
    works with joined-table for now)
 - automatic solving of cyclical references/dependencies (and putting 
    proper alter_table / post_update)
 - associations (many2many) - implicit and explicit
 - more? maybe


Example declarations:

import dbcook.usage.plainwrap as o2r
class Text( o2r.Type): pass

class Address( Base):
	place = Text()

class Person( o2r.Base):
	name = Text()
	address = o2r.Type4SubStruct( Address)
	friend  = o2r.Type4SubStruct( 'Person')

class Employee( Person):
	job = Text()

..... and no mentioning of tables, columns etc whatsoever .....

Once the mapping is built, any of these can be done:
 - use it as plain SA - session.query( class).. and similar
 - query-clause expressions can be automatically created from plain 
    python functions over objects' attributes, e.g.: 
 lambda self: (self.friend.manager.age < 40) & self.name.endswith('a')
 - generate a source of the equivalent plain SA-calls to build it

So far it is just a library. There is no single way to use it. The 
directory usage/ has 2 possible reflectors (things that walk the 
declared classes and gather info from them), one is just plain python 
(plainwrap.py), another is for my static_type/ framework. You can 
make your own for your own taste.

The usage/samanager thing tries to (correctly - context like) keep all 
related things in one place - mappings, dbs, engines, sessions, etc. 
If destroy() is requested, it'll try hard to clear all side-effects 
of its existence.

Certain pieces are (almost) independent and are usable as is without 
all the rest: expression.py, usage/hack*py, sa_generator.py - all 
SQLAlchemy related.

The tests/ directory contains 2 types of tests - sa/ which proves that 
the way SA is used in dbcook is correct/working, and mapper/other 
which check whether the cooker does right thing as result. It still 
uses makefile to run all stuff.

external dependencies: 
 - needs kjbuckets (from gadfly) for graph-arithmetics
 - needs sqlalchemy, 0.3.6+?
 - optional static_type/ framework - makes staticly-declared structs 
    (a-la java/C semantics) in python - do mail if interested.

Some todo's, long- or short- term:
 - nicer/some way of declaring collections 
     (SA: relation(.. use_list=True))
 - some documentation, translate all in both languages.
 - tests for all the stuff, in most of combinations, 
    instead of just trying this/that
 - generate sql-server-side functions, triggers etc
 - autoload / reverse-engineering
 - single-table inheritance
 - other reflectors/"syntaxes" - e.g. elixir-like 
 - concrete-polymorphism: polymunion of (type,id) key

have fun

Subject: itools 0.16.3 released
Message-ID: <469F4C4C.9020806@itaapy.com>

itools is a Python library, it groups a number of packages into a single
meta-package for easier development and deployment:

   itools.catalog        itools.i18n             itools.tmx
   itools.cms            itools.ical             itools.uri
   itools.csv            itools.odf              itools.vfs
   itools.datatypes      itools.pdf              itools.web
   itools.gettext        itools.rest             itools.workflow
   itools.handlers       itools.rss              itools.xhtml
   itools.html           itools.schemas          itools.xliff
   itools.http           itools.stl              itools.xml

Version 0.16.3 of itools does not use anymore the package uTidylib [1]
(it was required by itools.cms), now the itools API for (X)HTML is used
instead.

But the big news this Thursday is the new file handler (named "Table")
to manage structured data.  This feature is still in an experimental
state, the API will probably change in the next releases.

Another important change, the Virtual File System (itools.vfs) now can
open files in "append" mode.  This is supported by the local file system
layer, and by the itools.cms database.  So far only the handler Table
takes advantage of this feature to improve scalability.

All handlers have a new method, "abort_changes", which will reset the
changes made to a handler and not yet saved.  Folders have an specific
implementation that improves memory usage when a transaction is aborted,
or fails.

The itools.xhtml package has two new functions, "sanitize_stream" and
"sanitize_str"; they will clean an (X)HTML fragment of potentially
dangerous elements and attributes, like JavaScript code.

The (X)HTML document handlers have two new methods: "to_xhtml" and
"to_html".  They return a byte string that represents the state of the
handler, as XHTML and HTML respectively.

The HTML parser is now compatible with the XML parser, the events it
returns have the same structure.  And the state of the HTML document
handler is now identical to the state of the XHTML document handler.
(This way the itools.xhtml and itools.html packages are getting closer,
in preparation for a future merge.)

There is a fix in the XML parser (itools.xml), it did not correctly
parse attribute values when there was more than one entity reference.

And another small fix in the "set_prefix" function from itools.stl, now
the "" tags are also processed.

The reST support (itools.rest) has seen some changes to the API.  First
the function "to_html_events" will return an stream of (X)HTML events
from a reST text.  Second the new function "to_str(text, format)" is
recommended over "to_xml", "to_html" and "to_latex", which become
deprecated.  Last, the "Document" class has been removed, as it was
redundant (use the functions instead).

And the usual bunch of fixes for itools.cms; most notably the new
procedure for when the user forgets her password: now instead of
sending a new password by email we send a link to a form that allows
the user to choose her new password.  Also, a number of methods
have been deprecated, check the UPDATE-0.16.3 file for the details.

Subject: ANN: amplee 0.5.1
Message-ID: <46A0ACA9.90004@defuze.org>

All,

I am really pleased to announce version 0.5.1 of amplee, a Python
implementation of the Atom Publishing protocol as per draft-17 [1].

This version is a major release for amplee and will (unfortunately) break
existing applications using it due to some changes in its API, although
those modifications are minor and the design stays pretty much the same
allowing for an easier upgrade.


== What's new? ==

* Changed the member resource API to make it more robust and useful,
handling many common tasks for the application developer.

* Added support for a distinction of collection and public feed providing
a very simple mechanism to create and handle both types of feeds.

* Extended the collection API and fixed numerous bugs within.

* Added a tarfile storage that permits to store data in a tarball in a
transparent fashion (handy for multipart/form-data storage for instance).

* Added a memcache storage that can as a proxy  storage  to cache
resources in memcached server using either cmemcache or python-memcache.

* Made the storage API more robust and resilient to unicode vs byte string.

* Improved and enhanced the indexer module which can now also use
memcached to store indexes.

* Added a working (finally) example of amplee demonstrating its main
features [2].

* Made the unit tests more useful

* Added support for Etag in the HTTP handlers

* Added a contrib directory containing a schematron schema for Atom
related documents as well as a crawler.py module that can browse or test
your AtomPub service and reports a set of details about it (simple but
useful).

* Support for entry points has been extended and allows to support any
number of collections via the loader module.

* Gazillions of bugs have been fixed and hopefully carefully tested to
perish as they deserved.

* Fixed memcached indexer defect.

* Documentation added.

== Download ==

* easy_install -U amplee
* Tarballs http://www.defuze.org/oss/amplee/
* svn co https://svn.defuze.org/oss/amplee/

== Documentation ==

Subject: [ANN] Python documentation team looking for members!
Message-ID: 

Dear fellow Pythonistas,

as you may have heard, Python is going to get a new documentation system
soon [1].  As part of that effort, and in order to maintain the excellent
quality of the docs, we are looking for members of the maintainers team.
This is your chance to get involved with Python development!

There will be two main objectives of the group, or maybe two subgroups can
be formed:

* Maintaining the documentation contents:
    - processing user submitted comments, bugs and patches
    - helping out developers with docs-related matters, keeping an eye
      on commits to ensure quality
    - keeping the docs up-to-date, e.g. write new sections for new
      Python 3000 features

    The docs source will be in reStructuredText, which is already known to a
    relatively high percentage of Python developers.

    The new online version of the docs will contain features to add comments
    and suggest changes, so it is expected that there will be some amount
    of user involvement.


* Development of the toolset:
    - fixing bugs in the package
    - adding new output formats, e.g. info or pdf
    - adding new features to the web application
    - adapting it to new docutils features

    The software is written in pure Python. It is currently located in the
    docutils Subversion repository, at

Subject: ANN: setuptoolsbzr 0.2 - a setuptools plugin for Bazaar
Message-ID: 

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Bazaar[1] is a distributed version control system that provides many  
useful features over second generation vcs's like Subversion, and  
it's written in Python.

setuptoolsbzr is a plugin enabling Bazaar support for the also  
awesome setuptools[2] enhancements to Python's distutils.  With this  
plugin, you can manage your projects under Bazaar and setuptools will  
be able to find version controlled files when it creates packages of  
your project.

To use, all you need to do is add the following to your setup()  
function:

setup(
     # ...
     entry_points = {
         'setuptools.file_finders': [
             'bzr = setuptoolsbzr:find_files_for_bzr',
             ],
         },
     setup_requires = [
         'setuptoolsbzr',
         ],
     )

setuptools will do the rest.  You can of course grab the  
setuptoolsbzr package separately from the Python Cheeseshop[3].

One caveat: setuptoolsbzr requires that either the command line  
program bzr(1) be available on your $PATH or that the bzrlib package  
be installed in your Python's site-packages.  setuptoolsbzr has a  
dependency on the 'bzr' package but this dependency is disabled due  
to a minor bug in the bzr Cheeseshop tarball[4].  This may not affect  
you because why would you want to use setuptoolsbzr if you didn't  
already have bzr installed?  For now though, just install Bazaar  
manually via the tarball available on the bazaar-vcs.org site, or  
your OS's package manager and you should be good to go.  When the bug  
is fixed, I'll update setuptoolsbzr accordingly.

Enjoy,
- -Barry

I've just put it on my web page:

Release Announcement: PARLEY version 0.3

PARLEY is a library for writing Python programs that implement the Actor
model of distributed systems, in which lightweight concurrent processes
communicate through asynchronous message-passing. Actor systems typically
are easier to write and debug than traditional concurrent programs that
use locks and shared memory.

With version 0.3, PARLEY now supports the Greenlet execution model
(http://codespeak.net/py/dist/greenlet.html). Greenlets are lightweight
threads, similar to the tasklets supported by Stackless Python; unlike
tasklets, they do not require a special version of Python. PARLEY also
supports tasklets and traditional native threads, and it provides the
ability to switch between these modes of execution without substantial
code changes.

Version 0.3 also includes various bug fixes, additional features, and
documentation improvements.

Code samples, documentation, and source code can be found at the PARLEY
home page: http://osl.cs.uiuc.edu/parley/

PARLEY is licensed under the LGPL.

Subject: ANN: pyparsing1.4.7
Message-ID: <1185116799.263876.289200@n2g2000hse.googlegroups.com>

I just uploaded the latest release (v1.4.7) of pyparsing, and I'm
happy to say, it is not a very big release - this module is getting
to be quite stable.  A few bug-fixes, and one significant notation
enhancement: setResultsNames gains a big shortcut in this release
(see below).  No new examples in this release, sorry.

Here are the notes:

- NEW NOTATION SHORTCUT: ParserElement now accepts results names
  using a notational shortcut, following the expression with the
  results name in parentheses.  So this:

    stats = "AVE:" + realNum.setResultsName("average") + \
            "MIN:" + realNum.setResultsName("min") + \
            "MAX:" + realNum.setResultsName("max")

  can now be written as this:

    stats = "AVE:" + realNum("average") + \
            "MIN:" + realNum("min") + \
            "MAX:" + realNum("max")

  The intent behind this change is to make it simpler to define
  results names for significant fields within the expression, while
  keeping the grammar syntax clean and uncluttered.

- Fixed bug when packrat parsing is enabled, with cached ParseResults
  being updated by subsequent parsing.  Reported on the pyparsing
  wiki by Kambiz, thanks!

- Fixed bug in operatorPrecedence for unary operators with left
  associativity, if multiple operators were given for the same term.

- Fixed bug in example simpleBool.py, corrected precedence of "and"
  vs. "or" operations.

- Fixed bug in Dict class, in which keys were converted to strings
  whether they needed to be or not.  Have narrowed this logic to
  convert keys to strings only if the keys are ints (which would
  confuse __getitem__ behavior for list indexing vs. key lookup).

- Added ParserElement method setBreak(), which will invoke the pdb
  module's set_trace() function when this expression is about to be
  parsed.

- Fixed bug in StringEnd in which reading off the end of the input
  string raises an exception - should match.  Resolved while
  answering a question for Shawn on the pyparsing wiki.

========================================
Pyparsing is a pure-Python class library for quickly developing
recursive-descent parsers.  Parser grammars are assembled directly in
the calling Python code, using classes such as Literal, Word,
OneOrMore, Optional, etc., combined with operators '+', '|', and '^'
for And, MatchFirst, and Or.  No separate code-generation or external
files are required.  Pyparsing can be used in many cases in place of
regular expressions, with shorter learning curve and greater
readability and maintainability.  Pyparsing comes with a number of
parsing examples, including:
- "Hello, World!" (English, Korean, Greek, and Spanish(new))
- chemical formulas
- configuration file parser
- web page URL extractor
- 5-function arithmetic expression parser
- subset of CORBA IDL
- chess portable game notation
- simple SQL parser
- Mozilla calendar file parser
- EBNF parser/compiler
- Python value string parser (lists, dicts, tuples, with nesting)
  (safe alternative to eval)
- HTML tag stripper
- S-expression parser
- macro substitution preprocessor

What is ftputil?
----------------

ftputil is a high-level FTP client library for the Python programming
language. ftputil implements a virtual file system for accessing FTP
servers, that is, it can generate file-like objects for remote files.
The library supports many functions similar to those in the os,
os.path and shutil modules. ftputil has convenience functions for
conditional uploads and downloads, and handles FTP clients and servers
in different timezones.

= Other Groups =

There are 34 states with Python usergroups, leaving 16 without any Python
organizations at all -- and this is just in the United States.  We would like
to encourage the formation of more groups worldwide.  If you've been wishing
there were meetings near you, step forward and help initiate or revitalize
one.  There are experienced organizers waiting to mentor you on the mailing list:

Subject: Python Trainers, Promote Thyself!
Message-ID: <46A59DCE.2080004@taupro.com>

With the recent establishment of the wiki page on python.org for those who
offer training services for the Python language, we now have 23 listed, worldwide.

    http://wiki.python.org/moin/PythonTraining

Many of the trainers are individuals or small companies, and it can be hard to
get the attention of the big IT houses.  While skill credentials and a
portfolio of past training gigs are important, perhaps one of the best
promoters is when someone has actually experienced one of your classes.  They
gain insight into your speaking style, how you relate to the students and your
ability to explain complex technical subjects in an approachable way.  No
class syllabus can convey that.  The Python community has a valuable resource
that can give you the next best thing.  Screencasting!

Screencasting is a multimedia creation that focuses on the instructor's
desktop, with voiceover guidance.  It can be in the format of an online
slideshow, a guided sourcecode walkthrough or a follow-along interactive
session.  They can be as long or short as you wish and they have opportunities
for branding, by using custom wallpaper behind your talks desktop and musical
lead-in/fade-out.

Screencasts can be hosted on www.showmedo.com or, if done with a large font,
video.google.com.  They can also be embedded in your website while hosted
elsewhere, as shown at:

    http://www.python.org/doc/av/5minutes/

You can learn more about the details with a talk series I put together:

    Casting Your Knowledge, With Style
    http://www.showmedo.com/videos/series?name=bETR23HwS

But perhaps you're really busy on current projects and short on time. Consider
 arranging an audio interview about an upcoming seminar you're offering and
making it available as a podcast.  Ron Stephens of Python 411 makes available
an excellent collection of podcasts and may be interested in hosting yours.

Unlike face-to-face presentation opportunities, screencasts/podcasts have the
additional benefit that they promote your training offerings while you're busy
on other gigs.  It's almost like cloning yourself and having more time for
promotion.  It's all about leverage.

to meetup after the talks, we can disperse there. (Just look for area
reserved for Python Ireland).

More details on the wiki.

See you all there!

Subject: ANN: PyQwt-5.0.1 released
Message-ID: <20070726080606.27a86b8c@zombie.grenoble.cnrs.fr>

What is PyQwt ( http://pyqwt.sourceforge.net ) ?

- it is a set of Python bindings for the Qwt C++ class library which
  extends the Qt framework with widgets for scientific and engineering
  applications.   It provides a widget to plot 2-dimensional data and
  various widgets to display and control bounded or unbounded floating
  point values.

- it requires and extends PyQt, a set of Python bindings for Qt.

- it supports the use of PyQt, Qt, Qwt, and optionally NumPy or SciPy
  in a GUI Python application or in an interactive Python session.

- it runs on POSIX, Mac OS X and Windows platforms (practically any
  platform supported by Qt and Python).

- it plots fast: displaying data with 100,000 points takes about 0.1 s
  (PyQwt with Qt-3 is faster than with Qt-4).

- it is licensed under the GPL with an exception to allow dynamic linking
  with non-free releases of Qt and PyQt. 


The most important new features of PyQwt-5.0.1 are:
- support for Qt-4.3, SIP-4.7, and PyQt-4.3
- support for the N-D array interface specification
  ( http://numpy.scipy.org/array_interface.shtml ).
- the iqt module also supports an interactive Python session without the
  help of the GNU readline module.
- PyQwt is now part of the PyQt-Py2.5-gpl-4.3 binary installer for Windows
  ( http://www.riverbankcomputing.com/Downloads/PyQt4/GPL/ )

The most important bug fix in PyQwt-5.0.1 is:
- removal of a huge memory leak in the conversion from an array to a QImage.

PyQwt-5.0.1 supports:
1. Python-2.5, or -2.4. 
2. PyQt-3.17.
3. PyQt-4.3, or PyQt-4.2.
3  SIP-4.7, or SIP-4.6.
4. Qt-3.3, or Qt-3.2.
5. Qt-4.3, or Qt-4.2.
6. Recent versions of NumPy, numarray, and/or Numeric.


Enjoy -- Gerard Vermeulen

Subject: ANN: PyMTP 0.0.1
Message-ID: <46A8040B.5060108@nick125.com>

Hello!

After several days of work, I'm glad to announce the release of PyMTP 
0.0.1! PyMTP provides a Python API for access MTP devices, such as 
Creative MP3 players, some iRiver MP3 players, and so on.

Get it
-------

PyMTP 0.1 is available at http://nick125.com/smedia/pymtp/pymtp-0.0.1.tar.gz

Installing PyMTP
-----------------------

PyMTP requires for installation:

* Python 2.5 -or- ctypes manually installed
* Libmtp (PyMTP was developed around 0.1.5, but, some previous versions 
may work)

To install PyMTP, run python setup.py install as root.

Note: I haven't tested PyMTP on Win32, due to the lack of having a Win32 
machine available. Theoretically, it should work, providing that libusb, 
libmtp, ctypes, and Python is installed.

Feedback
------------

Please send any feedback about PyMTP, include bug reports, feature 
requests, and so on to me at nick at nick125.com

Regards,
Nick

Subject: ANN: sortmail - module to sort incoming mail for delivery to multiple
	destinations
Message-ID: <87bqdzzr08.fsf@unicorn.ahiker.homeip.net>


http://primate.net/~itz/sortmail/sortmail-20070718.tar.gz

This is a python module to help in delivery of mail to multiple
mailboxes, similar to procmail and the Perl module Mail::Sort. There is
necessarily some overlap with the email package bundled with Python but
this one is optimized for fast matching on headers and fast delivery,
and treats the body of the mail as just a string, i. e. there is no
specific MIME support. This is a free package, please see the file
LICENSE in this directory for the terms of use. Documentation is
available via pydoc.

New in release 20070718: documentation really is available :)
A realistic example of a delivery script using the module is included.

Subject: itools 0.16.4 released
Message-ID: <46A86756.3020203@itaapy.com>


itools is a Python library, it groups a number of packages into a single
meta-package for easier development and deployment:

   itools.catalog        itools.i18n             itools.tmx
   itools.cms            itools.ical             itools.uri
   itools.csv            itools.odf              itools.vfs
   itools.datatypes      itools.pdf              itools.web
   itools.gettext        itools.rest             itools.workflow
   itools.handlers       itools.rss              itools.xhtml
   itools.html           itools.schemas          itools.xliff
   itools.http           itools.stl              itools.xml

For the first time in a looong time we have tested itools on Windows.
Now itools installs and the unit tests pass.

As a side effect the "vfs.move" method (from "itools.vfs") now is
cross-platform (and faster).

There is a new, and simple, handler for Gzip files (in "itools.handlers").

The document type declaration (DOCTYPE) is correctly parsed now, by
both "itools.xml" and "itools.html".  And an small bug has been fixed
in the (X)HTML sanitizer.

The CMS ("itools.cms") has a couple of enhancements.  Now emails are
sent asynchronously; if sending an email fails, it will be tried again
later.

The forum posts are now HTML instead of plain text.  The HTML editor
is used to edit the posts, and the HTML is sanitized to avoid security
problems.

There are also several fixes: in the tracker, the calendar, and when
cut&paste a document in the same folder.


Credits:

  - Nicolas Deram worked on the tracker;
  - David Hughes helped testing itools on Windows;
  - J. David Ib??ez worked on itools.cms, itools.xml and the unit tests;
  - Sylvain Taverne worked on the forum and fixed several bugs;

Subject: ceODBC 1.0
Message-ID: <703ae56b0707260724y654f1fefw8409a9e75d639e81@mail.gmail.com>

What is ceODBC?

ceODBC is a Python extension module that enables access to databases using the
ODBC API and conforms to the Python database API 2.0 specifications with a few
exceptions. I have tested this on Windows against SQL Server, Access
and Oracle. On Linux I have tested this against PostgreSQL.


Where do I get it?

http://ceodbc.sourceforge.net


Background

I recently had the need for accessing SQL Server and Access databases
and checked out the available options. The odbc module that comes with
the win32 extensions worked reasonably well but it had a number of
deficiencies and it was clear from the documentation that no further
work was intended. I then checked out mxODBC. It is a great module but
for my purposes the cost was too great to warrant purchasing it. I
decided to see how much effort writing my own module would take and
discovered that, with a copy of cx_Oracle as a starting point, the
effort was minimal. With the hope that this module might prove useful
to others as it already has to me, I am making this release. Any and
all feedback welcome.

Message-ID: <20070726143035.GF30176@phd.pp.ru>

Hello!

I'm pleased to announce the 0.8.5 release of SQLObject.


What is SQLObject
=================

SQLObject is an object-relational mapper.  Your database tables are described
as classes, and rows are instances of those classes.  SQLObject is meant to be
easy to use and quick to get started with.

SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and
Firebird.  It also has newly added support for Sybase, MSSQL and MaxDB (also
known as SAPDB).

News since 0.8.4
----------------

Bug Fixes

* Replaced calls to style.dbColumnToPythonAttr() in joins.py by name/dbName
  lookup in case the user named columns differently using dbName.

* Minor correction in the tests: we fully support EnumCol in Postgres.

* MySQLConnection now recognizes Enum, Double and Time columns when drawing the
  database scheme from DB.

* Minor fix in FirebirdConnection.fromDatabase.

* Fixed a bug with default field values for columns for firebird connection.

* Prevent a deadlock in declarative.threadSafeMethod() by not reacquiring
  the class lock.

* Run post_funcs after sending RowCreatedSignal.

* Suppress the second RowUpdateSignal in .set() called from ._SO_setValue().

* Fixed a bug in col.createSQL().

* Fixed a bug in converting date/time for years < 1000 (time.strptime()
  requires exactly 4 digits for %Y, hence a year < 1000 must be 0-padded).

Other Changes
~~~~~~~~~~~~~

* Changed string quoting style for PostgreSQL and MySQL from \' to ''.

          eGenix EuroPython 2007 Presentations & Videos

________________________________________________________________________

eGenix is pleased to announce the immediate availability of PDF and
Flash video versions of the presentations we gave at this years
EuroPython 2007 conference in Vilnius.

This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/EuroPython-2007-Presentations.html
________________________________________________________________________

INTRODUCTION

The EuroPython Conference is the one of the premier conferences for
Python & Zope users and developers. This year it was being held from
the 9th to 11th July in Vilnius, Lithuania.

eGenix was one of the founding members of the EuroPython conference
team and played a major role in organizing the first EuroPython
conference in the year 2002.

Since then we have attended every EuroPython conference to meet up
face-to-face with the people from the Python & Zope communities and
have given regular talks at these conferences.

________________________________________________________________________

TALKS AT EUROPYTHON 2007

We gave the following two talks at the conference. The presentations
are available for viewing and download from our Presentations and
Talks section:

        http://www.egenix.com/library/presentations/

As special feature, we have added talk videos in addition to providing
the slide PDFs. You can view the talks online if you have the Adobe
Flash Player 8 or later installed.

* Parsing Languages with mxTextTools

mxTextTools comes with a high performance Tagging Engine for text and
Unicode
data which can be used to tokenize and parse languages. The resulting
abstract
syntax tree can then be hooked up to a generator to build a complete and
fast
compiler in pure Python. The talk gives a short introduction to the way the
mxTextTools Tagging Engine works and how it can be used to build compilers.
mxTextTools is an eGenix Open Source product available as part of the
eGenix mx
Base Distribution.

* An introduction to working with relational databases from Zope

Although Zope has been around for quite a while, it continues to find
new users
particularly amongst non-programmers who are looking for a way to work with
existing data which is usually in some relational database (PostgreSQL,
MySQL,
MS SQL, Oracle, DB2, etc.). One of the reasons for this is that Zope
provides an
extremely powerful, yet secure, through-the-web programming environment.

The presentation is directed towards new users and will provide a brief
introduction by example into the Zope way of doing things. At the same
time it
highlights how working within Zope is automatic training in good programming
methodology: data management is delegated to ZSQL methods, PythonScripts
act as
controllers and Zope Page Templates provide the views. Together they
encourage
modularity and reusability. The sample application and database are
available
for download.

Enjoy,

Subject: ANN: mod_wsgi 1.0c1 now available
Message-ID: <1185499165.002764.234240@o61g2000hsh.googlegroups.com>

The initial release candidate for version 1.0 of mod_wsgi is now
available
for final testing. The software and documentation are both available
from:

  http://www.modwsgi.org

The mod_wsgi package consists of an Apache web server module designed
and
implemented specifically for hosting Python based web applications
that
support the WSGI interface specification.

Examples of major Python web frameworks and applications which are
known to
work in conjunction with mod_wsgi include CherryPy, Django, MoinMoin,
Pylons, Trac and TurboGears.

Hosted WSGI applications may be run in 'embedded' mode, in the style
of
mod_python, or 'daemon' mode, in a style somewhat similar to that of
mod_fastcgi.

Embedded mode would generally be used where dedicated servers are
available. The mode would allow the scalability and process management
features of Apache to be fully utilised to achieve maximum performance
for
your application.

Daemon mode would instead be used where applications need to be
separated
from each other. This mode would thus be suitable for shared hosting
environments where applications need to be run in distinct processes
running as the user which owns the application and not the user which
Apache runs as.

The Apache module can be compiled for and used with either Apache 1.3,
2.0
or 2.2, although daemon mode is only available on Apache 2.X running
on
UNIX. When running on UNIX systems, either the single threaded
'prefork' or
multithreaded 'worker' Apache MPMs can be safely used.

If you have any questions about mod_wsgi or wish to provide feedback,
use
the Google group for mod_wsgi found at:

  http://groups.google.com/group/modwsgi

Enjoy

Subject: ANN: PyQwt-4.2.3 released
Message-ID: <20070727072418.1a13679e@zombie.grenoble.cnrs.fr>

What is PyQwt ( http://pyqwt.sourceforge.net ) ?

- it is a set of Python bindings for the Qwt C++ class library which
  extends the Qt framework with widgets for scientific and engineering
  applications.   It provides a widget to plot 2-dimensional data and
  various widgets to display and control bounded or unbounded floating
  point values.

- it requires and extends PyQt, a set of Python bindings for Qt.

- it supports the use of PyQt-3, Qt-3, Qwt-4.2, the Numerical Python
  extensions (any combination of NumPy, numarray, and Numeric) and optionally
  SciPy in a GUI Python application or in an interactive Python session.

- it runs on POSIX, Mac OS X and Windows platforms (practically any
  platform supported by Qt and Python).

- PyQwt-4.2.3 can coexist with PyQwt-5.0.x (for Qt-3 and Qt-4)
 
This is a maintenance release with backports of the newest features in
PyQwt-5.0.1 to PyQwt-4.2.3.  PyQwt-4.2.3 should not be used for new code.

New features and bug fixes in PyQwt-4.2.3 are:
- support for SIP-4.7, and PyQt-3.17.3.
- support for the N-D array interface specification
  ( http://numpy.scipy.org/array_interface.shtml ) allows to copy data out
  of NumPy arrays without enabling support for NumPy during the compilation
  of PyQwt.
- the iqt module also supports an interactive Python session without the
  help of the GNU readline module.
- removal of a huge memory leak in the conversion from an array to a QImage.


PyQwt-4.2.3 supports:
1. Python-2.5.x, or -2.4.x.
2. PyQt-3.17.x.
3  SIP-4.7.x, or -4.6.x.
4. Qt-3.3.x, or -3.2.x.

Subject: ANN: M2Crypto 0.18
Message-ID: 

M2Crypto is the most complete Python wrapper for OpenSSL featuring RSA,
DSA, DH, HMACs, message digests, symmetric ciphers (including AES); SSL
functionality to implement clients and servers; HTTPS extensions to
Python's httplib, urllib, and xmlrpclib; unforgeable HMAC'ing
AuthCookies for web session management; FTP/TLS client and server;
S/MIME; ZServerSSL: A HTTPS server for Zope and ZSmime: An S/MIME
messenger for Zope.

Download links on the homepage at
http://chandlerproject.org/Projects/MeTooCrypto.

Changelog:

- Added EVP.pbkdf2 to derive key from password
- X509_Store_Context.get1_chain added
- Added X509_Name.__iter__, __getitem__, get_entries_by_nid which allow
  iterating over all X509_Name_Entries or getting just all commonName
  entries, for example
- Added X509_Name_Entry.get_object, get_data, set_data
- Added back PKCS7.get0_signers (was removed in 0.16)
- X509_Extension.get_value accepts flag and indent parameters.
- support multiple dNSName fields in subjectAltName
- support multiple commonName fields for SSL peer hostname checking
- Checking for erroneous returns from more OpenSSL EVP_* functions,
  which means that certain things that used to fail silently will now
  raise an EVP.EVPError; affected m2 functions are: digest_final,
  cipher_init, cipher_update, cipher_final and sign_update. sign_final
  will now raise EVP.EVPError instead of SystemError as well.
- Fixed Pkey.verify_final to take a sign parameter
- If a subjectAltName extension of type dNSName is present in peer
  certificate, use only the dNSNames when checking peer certificate
  hostname, as specified by RFC 2818. If no dNSNames are present, use
  subject commonName.
- Fixed memory leaks in m2 functions ec_key_new_by_curve_name,
  pkey_get_modulus, ecdsa_verify, threading_init and
  X509.X509.verify, X509.X509_Stack (which manifested for example when
  calling X509.new_stack_from_der), SSL.Connection (which manifested
  with some connection errors or when connect was never called), twisted
  wrapper, SSL.Connection.makefile (in BIO.IOBuffer really)
- Fixed threading regressions introduced in 0.16,
  by Aaron Reizes and Keith Jackson
- Added SSL session caching support to HTTPSConnection, by Keith Jackson
- Added the ability to save and load DER formatted X509 certificates and
  certificate requests, by Keith Jackson
- m2xmlrpclib.py fixed to work with Python 2.5, by Miloslav Trmac
- 64-bit correctness fixes, by Miloslav Trmac
- Added X509_Name.as_hash, by Thomas Uram
- Moved --openssl option from general setup.py option to build_ext
  option, meaning you need to do: python setup.py build build_ext
  --openssl=/path, by Philip Kershaw
- Fixed build problem affecting certain systems where OpenSSL was built
  without EC support
- M2CRYPTO_TEST_SSL_SLEEP environment variable controls how long to
  sleep after starting the test SSL server. Default is 0.5, but 0.1 or
  even 0.05 might work with modern computers. Makes tests finish
  significantly faster.

Subject: The Cython project
Message-ID: <46ab2ba6$0$5698$9b4e6d93@newsspool2.arcor-online.net>

Hi all,

I just wanted to announce the availability of the first official Cython
release (0.9) by the SAGE maintainers William Stein and Robert Bradshaw (and a
bit by myself).

http://www.cython.org/

Cython is based on the well-known Pyrex translator by Greg Ewing, but supports
more cutting edge functionality and optimizations. It was formerly known as
the SageX fork of Pyrex.

Some of the highlights compared to the latest Pyrex version:

   1. Conditional expressions (a if blah else b)
   2. List comprehensions
   3. Optimized looping (for whatever in blah: is much faster in Cython)
   4. Better support for module imports: import a.b.cython_module
   5. 64-bit Python 2.5 support

and there's a lot more in the queue ...

Cython has a site up on launchpad, so if you have any questions or
suggestions, found any bugs or want to contribute patches, please visit the
project there:

https://launchpad.net/cython/

Have fun,
Stefan

    * read everything the PyPy guys have ever written (particularly

no social life, they get treated like crap by everyone.  They can get paid
pretty well but then they spend all the money on useless electronic junk so
they still live like bums.  There is only one reason to be a programmer,
which is that the drive to program burns in you like a fire.  But in that
case don't ask how to become a programmer, because you are already one, so

Subject: MailingLogger 3.2.0 Released!
Message-ID: <46AF91EE.6020700@simplistix.co.uk>

With help from Jens Vagelpohl, I'm pleased to announce a new release of 
Mailinglogger that now supports filtering of log entries...

Mailinglogger enables log entries to be emailed either as the entries
are logged or as a summary at the end of the running process.

This pair of enhanced emailing handlers for the python logging framework
is now available as a standard python package and as an egg.

The handlers have the following features:

- customisable and dynamic subject lines for emails sent

- emails sent with an X-Mailer header for easy filtering

- flood protection to ensure the number of emails sent is not excessive

- support for SMTP servers that require authentication

- fully documented and tested

In addition, extra support is provided for configuring the handlers when
using ZConfig, Zope 2 or Zope 3.

Installation is as easy as:

easy_install mailinglogger

For more information, please see:

cheers,

Chris

Subject: Python Package Index hostname change
Message-ID: <46AFA27A.4090700@v.loewis.de>

The Python Packaging Index (the software formerly known
as Cheeseshop) is now available at

http://pypi.python.org/pypi

The old addresses (www.python.org/pypi, and
cheeseshop.python.org/pypi) will continue to work,
either as aliases or using HTTP redirections.

The software was renamed to its old name
(PyPI - Python Package Index), as the Cheeseshop
name was ever confusing people unfamiliar with
British television comedy sketch (and puzzling
even to people familiar with the sketch, as
you *can* get packages from the package index).

If you would like to discuss PyPI and its future,
please join catalog-sig at python.org.

Regards,
Martin
