NEWS

The 2.2.3 release of our mxODBC Zope/Plone Database Adapter product is
a patch level release of the popular ODBC database interface for Plone
and Zope. It includes these enhancements and fixes:

Feature Updates
---

 * We have integrated a new option to force serialized connects on a
   per Zope connection object basis. This can be used to work around
   bugs in ODBC drivers which are not fully thread-safe in the connect
   phase. The option is disabled per default.

Driver Compatibility Enhancements
-

 * ODBC driver compatibility updated. Upgraded to the latest mxODBC
   3.3.5 release, adding compatibility enhancements for MS SQL
   Server. See the mxODBC 3.3.5 release announcements for full
   details.

Installation Enhancements
-

 * Added pip install compatibility to mxODBC Zope DA by creating
   prebuilt archives and uploading a web installer to PyPI. This can
   be useful if you are installing Zope or Plone using a
   requirements.txt type approach, e.g. using

   pip install ThreadLock Products.ZSQLMethods egenix-mxodbc-zopeda

 * Enabled creating wheels from the prebuilt archives, which helps
   when running pip with the wheels package installed. pip then tries
   to build wheels during installation and caches them for future
   reuse.

The complete list of changes is available on the mxODBC Zope DA
changelog page.

The 2.2.2 release of our mxODBC Zope/Plone Database Adapter product is
a patch level release of the popular ODBC database interface for Plone
and Zope. It includes these enhancements and fixes:

Driver Compatibility Enhancements
-

 * Reenabled returning cursor.rowcount for FreeTDS >= 0.91. In
   previous versions, FreeTDS could return wrong data for .rowcount
   when using SELECTs.

Fixes
-

 * Removed exists() built-in from mxODBC Zope DA's implicit addition
   of new built-ins via mxTools.

   This resolves a hard to track bug where the new built-in could
   potentially override the TAL python:exists function (in
   e.g. tal:condition="exists:something"). See this
   Products.CMFEditions fix for an example where the problem
   surfaced. This is a bug in TAL (it shouldn't give preference to
   built-ins over its own helpers), but we're providing the fix as
   easy work-around.

[Zope] ANN: eGenix ThreadLock Distribution 2.13.0.1

[eGenix Team: M.-A. Lemburg]

ANNOUNCING

   eGenix.com ThreadLock Distribution

 Version 2.13.0.1


 eGenix is making a ThreadLock binary distribution
  available to simplify the setup for users of our mxODBC
  Plone/Zope database adapter.


This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-ThreadLock-Distribution-2.13.0.1.html



INTRODUCTION

Several people have approached us about a problem they are facing
with installing our mxODBC database adapter for Plone and Zope:

http://www.egenix.com/products/zope/mxODBCZopeDA/

The adapter product has dependencies on
 * ThreadLock
 * Products.ZSQLMethods

The Products.ZSQLMethods package is a pure Python package, so it
installs fine on all platforms.

ThreadLock comes with a Python C extension, so buildout needs
to either find egg files for the platforms or have a compiler
installed to build the C extensions.

On Unix platforms, installing a compiler is fairly straight forward,
but on Windows setting up compilers for Python is difficult and
the ThreadLock entry on PyPI only comes with egg files for Python
2.6 on Windows.



SOLUTION

To overcome this problem, we have taken the ThreadLock package
and created an internal setup to have it compiled by our
build farm.

You can now use these buildout configuration settings to pull
the egg files from our indexes.

For UCS2 Python builds (16-bit Unicode on Unix, Python for Windows):


[buildout]
...
find-links =
...
https://downloads.egenix.com/python/index/ucs2/
eggs =
...
ThreadLock

[versions]
...
ThreadLock = 2.13.0.1


For UCS4 Python builds (32-bit Unicode on Unix):


[buildout]
...
find-links =
...
https://downloads.egenix.com/python/index/ucs4/
eggs =
...
ThreadLock

[versions]
...
ThreadLock = 2.13.0.1


Available binaries
--

We provide egg files for Linux x86 and x64, Windows x86 and x64 as
well as the source package as fallback solution. The binaries were
compiled with Python 2.4, 2.5, 2.6 and 2.7.

Version number
--

Note that we have added a build number to the package version. This
allows us to issue updates to the package builds should these be
necessary and also makes sure that your buildout will use the packages
from our indexes instead of PyPI or other indexes.

NEWS

We are pleased to announce the new version 2.1.1 of our mxODBC
Zope/Plone Database Adapter product.

Feature Enhancements


 * Added a new connection property "ODBC cursor type" which allows
   easily adjusting the ODBC cursor type to be used for mxODBC Zope DA
   connection objects.

   This new property allows enhancing the performance of the adapter
   significantly, when using it with MS SQL Server or IBM DB2 database
   backends. Please see below for details.

Driver Compatibility


 * MS SQL Server performance can now be much enhanced, and increased
   to levels beyond that of previous mxODBC Zope DA releases, by
   adjusting the connection ODBC cursor type to "Forward only
   cursors".

   The performance increase compared to mxODBC Zope DA 2.1.0 is
   enormous: from 2-3x faster executes/fetches for average queries, up
   to 300x faster for simple cases.

   In mxODBC Zope DA 2.2, we will switch to using "Forward only
   cursors" per default for all database backends.

 * IBM DB2 can benefit from the same performance enhancements using
   "Forward only cursors".

   The effect is a lot smaller, but still noticeable: up to 2x faster
   executes/fetches with forward-only cursors, compared to mxODBC Zope
   DA 2.1.0.

 * Added documentation to explain the different cursor types,
   compatibility with different database backends and effects on
   performance.

Fixes
-

 * Fixed the installation instructions to be more generic and easily
   adaptable to Plone and Zope installations on both Windows and Unix
   platforms.

[Zope] ANN: eGenix pyOpenSSL Distribution 0.10.0-1.0.0a

[eGenix Team: M.-A. Lemburg]

ANNOUNCING

   eGenix.com pyOpenSSL Distribution

  Version 0.10.0-1.0.0a


 An easy-to-install and easy-to-use distribution
 of the pyOpenSSL Python interface for OpenSSL -
available for Windows, Mac OS X and Unix platforms


This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-pyOpenSSL-Distribution-0.10.0-1.0.0a-1.html



INTRODUCTION

The eGenix.com pyOpenSSL Distribution includes everything you need to
get started with SSL in Python.

It comes with an easy-to-use installer that includes the most recent
OpenSSL library versions in pre-compiled form, making your application
independent of OS provided OpenSSL libraries:

http://www.egenix.com/products/python/pyOpenSSL/

pyOpenSSL is an open-source Python add-on that allows writing SSL/TLS-
aware network applications as well as certificate management tools:

https://launchpad.net/pyopenssl/

OpenSSL is an open-source implementation of the SSL/TLS protocol:

http://www.openssl.org/



NEWS

This new release of the eGenix.com pyOpenSSL Distribution updates the
included pyOpenSSL version to 0.10.0 and the included OpenSSL version
to 1.0.0a.


Main new features in pyOpenSSL 0.10.0 (from the announcement)
-

* pyOpenSSL 0.10 exposes several more OpenSSL APIs, including
  support for running TLS connections over in-memory BIOs, access
  to the OpenSSL random number generator, the ability to pass
  subject and issuer parameters when creating an X509Extension
  instance, more control over PKCS12 creation and an API for
  exporting PKCS12 objects, and APIs for controlling the client CA
  list servers send to clients.

* Several bugs have also been fixed, including a crash when
  certain X509Extension instances are deallocated, a mis-handling
  of the OpenSSL error queue in the X509Name implementation,
  Windows build issues, and a possible double free when using a
  debug build.

See Jean-Paul Calderone's full announcement for all details:

https://launchpad.net/pyopenssl/+announcement/4318


New features in OpenSSL 1.0.0a since our last release
-

The main new features in OpenSSL 0.9.8m is the new support for RFC
5746, which addresses the SSL renegotiation problem found in earlier
OpenSSL versions.

* RFC 5746 - Transport Layer Security (TLS) Renegotiation
  Indication Extension: http://tools.ietf.org/html/rfc5746

* For a complete list of changes see:
  http://www.openssl.org/news/news.html

Version 0.9.8n fixes this vulnerability (see
http://www.openssl.org/news/secadv_20100324.txt):

* "Record of death" vulnerability in OpenSSL 0.9.8f through
  0.9.8m

Version 1.0.0 adds many new features, including (see
http://www.openssl.org/news/news.html):

* Support for Whirlpool hash algorithm
* Support for GOST cipher

Version 1.0.0a fixes two security issues (see
http://www.openssl.org/news/secadv_20100601.txt):

* Invalid ASN1 module definition for CMS.
* Invalid Return value check in pkey_rsa_verifyrecover


New features in the eGenix pyOpenSSL Distribution
-

* The embedded OpenSSL libs will now look for certificates in
  /etc/ssl on Unix platforms and /System/Library/OpenSSL on
  Mac OS X

  Note that it's usually better to explicitly tell OpenSSL where
  to look for trusted certificates via
  .load_verify_locations(None, certs_dir) than to rely on the
  above defaults using context.set_default_verify_paths()

* Added support for Win64 and precompiled Python 2.6 compatible
  binaries for that platform (you can find the OpenSSL libs in
  openssl-win64/vc9)

* Added support for Mac OS X 10.6 on Intel x64.

* Added .egg Distributions for Python 2.4 as well (in order to
  support Plone 3).


As always, we provide binaries that include both pyOpenSSL and the
necessary OpenSSL libraries for all supported platforms: Windows x86
and x64, Linux x86 and x64, Mac OS X PPC, x86 and x64.

Due to popular demand, we've also added .egg-file format versions of
our eGenix.com pyOpenSSL Distribution for Windows, Linux and Mac OS X
to the available download options.

These makes setups using e.g. zc.buildout and other egg-file based
installers a lot easier.

All of these methods have issues and there's always the possibility
of them returning NULL or, even worse, wrong values (e.g. due to
a trigger or stored procedure inserting rows as result of the initial
insert).

I'd suggest to consider a somewhat different approach:

Method 1:

When inserting a row into a table, you typically know that a
certain combination of column values has to be unique (perhaps
even protected by an additional constraint like a unique index).

After the insert query the identity column value by using this
column value combination.

That will work in all cases and is more robust than any of the
above helper functions.

Method 2:

Another strategy that we often use is based on probability:
instead of letting the database determine an identity value,
we chose one using a random number generator (RNG).

Chances are high that the identity value hasn't been used if
you use a good RNG, so it's very likely to be able to insert new
rows without problems.

In the event of a collision, the database will raise an error
and you can then choose a different identity value, again
based on an RNG.

Method 2 has the advantage of knowing the identity value
before the insert actually happens. That's often useful
and it (usually) avoids the extra query needed by method 1.

NEWS

We are pleased to announce a new version 2.0.1 of our mxODBC Zope DA
product.

With the patch level 2.0.1 release we have backported the mxODBC Zope DA
product to also run on Zope 2.10, 2.11 as well as Python 2.4. This was
done to meet popular demand, since Plone 3 still uses these Zope and
Python versions.

The mxODBC Zope DA is now fully compatible with all recent Plone
versions, including the upcoming Plone 4.0 release. Please see the
mxODBC Zope DA documentation for details on how to install the
product for use in Plone.

Compared to the previous 1.0 version of the mxODBC Zope DA, the 2.0
version includes these enhancements:

 * Includes mxODBC 3.1 with updated support for many current ODBC
   drivers, giving you more portability and features for a wider
   range of database backends.

 * Mac OS X 10.6 (Snow Leopard) support.

 * Python 2.4, 2.5 and 2.6 support.

 * Zope 2.10, 2.11 and 2.12 support.

 * Zero maintenance support to automatically reconnect the
   Zope connection after a network or database problem.

 * More flexible Unicode support with options to work with
   pure Unicode, plain strings or mixed setups - even for
   databases that don't support Unicode

 * Automatic and transparent text encoding and decoding

 * More flexible date/time support including options to work
   with Python datetime objects, mxDateTime, strings or tuples

 * New decimal support to have the Zope DA return decimal
   column values using Python's decimal objects.

 * Fully eggified to simplify easy_install and zc.buildout based
   installation

INTRODUCTION

The eGenix mxODBC Zope Database Adapter allows you to easily connect
your Zope or Plone installation to just about any database backend on
the market today, giving you the reliability of the commercially
supported eGenix product mxODBC and the flexibility of the ODBC
standard as middle-tier architecture.

The mxODBC Zope Database Adapter is highly portable, just like Zope
itself and provides a high performance interface to all your ODBC data
sources, using a single well-supported interface on Windows, Linux,
Mac OS X, FreeBSD and other platforms.

This makes it ideal for deployment in ZEO Clusters and Zope hosting
environments where stability and high performance are a top priority,
establishing an excellent basis and scalable solution for your Plone
CMS.


NEWS

We are pleased to announce a new version 2.0 of our mxODBC Zope DA
product.

The new version was changes to conform with the new Zope 2.12 layout
and installation system and includes many enhancements over our
previous 1.0 version:

 * Includes mxODBC 3.1 with updated support for many current ODBC
   drivers, giving you more portability and features for a wider
   range of database backends.

 * Mac OS X 10.6 (Snow Leopard) support.

 * Python 2.5 and 2.6 support.

 * Zero maintenance support to automatically reconnect the
   Zope connection after a network or database problem.

   pure Unicode, plain strings or mixed setups - even for
   databases that don't support Unicode

 * Automatic and transparent text encoding and decoding

 * More flexible date/time support including options to work
   with Python datetime objects, mxDateTime, strings or tuples

 * New decimal support to have the Zope DA return decimal
   column values using Python's decimal objects.

 * Fully eggified to simplify easy_install and buildout based
   installation

Here is a free (as in freedom) software created by Andreas Jung:

  http://pypi.python.org/pypi/z3c.sqlalchemy

You will be required to install:

1. "SQLAlchemy" (Object Relational Mapper)
http://www.sqlalchemy.org

More details about using M$ SQL Server with SQLAlchemy:
  http://www.sqlalchemy.org/docs/05/reference/dialects/mssql.html

2. "pyodbc" (Python DB API 2.0 compatible module)
http://pyodbc.sourceforge.net/

3. "FreeTDS" (ODBC Driver for M$ SQL Server)
http://www.freetds.org/

4. "unixODBC" (ODBC Manager)
http://www.unixodbc.org/

Well, it's all very easy to setup.  More detailed steps:

1. Install Python

2. Install unixODBC

   While configuring unixODBC use "--disable-gui" option::

 $ ./configure --prefix=/path/to/usr --disable-gui

3. Install FreeTDS

 While installing FreeTDS use these options::

   $ ./configure --prefix=/path/to/usr --with-tdsver=8.0
--with-unixodbc=/path/to/usr/

4. Configure "odbc.ini"

   In the "/path/to/usr/etc/odbc.ini" file, add something like
   this::

 [db_connections]
 first_db = MS SQL Server

 [first_db]
 Driver = FreeTDS
 Description = My First Database
 Trace = No
 Server = 192.168.1.18
 Port = 1433
 Database = test_database

5. Configure "odbcinst.ini"

 [FreeTDS]
 Description = v0.68 with protocol v8.0
 Driver = /path/to/usr/lib/libtdsodbc.so
 UsageCount = 1

5. Set environment variables

 ODBCINI="/path/to/usr/etc/odbc.ini"
 ODBCINSTINI="/path/to/usr/etc/odbcinst.ini"
 LD_LIBRARY_PATH="/path/to/usr/lib"
 export ODBCINI ODBCINSTINI LD_LIBRARY_PATH

   To test your connection:

 /path/to/usr/bin/isql first_db username password

6. Isstall "pyodbc"

   (Refer: http://www.easysoft.com/developer/languages/python/pyodbc.html)

   Here is some relevant text:

   To build pyodbc against unixODBC, you need to tell the compiler
   and linker where to find the unixODBC include files and
   libraries. To do this, open setup.py in a text editor and find
   these lines:

 extra_compile_args = None
 extra_link_args= None

   Edit the second line so that it looks likes this:

 extra_compile_args = None
 extra_link_args= ['-L/path/to/usr/lib']

   Find this line:

 extra_compile_args = ['-Wno-write-strings']

   Edit the line so that it looks like this:

 extra_compile_args = ['-Wno-write-strings', '-I/path/to/usr/include']

7. Install SQLAlchemy
8. Install z3c.sqlalchemy


If you succeed with this, can you create a tutorial about how to do
it ? :)

Baiju M

[Zope] ANN: eGenix mxODBC Connect 1.0.1 - Python Database Interface

[eGenix Team: M.-A. Lemburg]

ANNOUNCING
  eGenix.com mxODBC Connect

  Python Database Interface

Version 1.0.1


   Our new client-server product for connecting Python applications
  to relational databases - from all major platforms


This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-mxODBC-Connect-1.0.1-GA.html



INTRODUCTION

The mxODBC Connect Database Interface for Python allows users to
easily connect Python applications to all major databases on the
market today in a highly portable and convenient way.

Unlike our mxODBC Python extension, mxODBC Connect is designed
as client-server application, so you no longer need to find production
quality ODBC drivers for all the platforms you target with your Python
application.

Instead you use an easy to install Python client library which
connects directly to the mxODBC Connect database server over the
network.

This makes mxODBC Connect the ideal basis for writing cross-platform
database programs and utilities in Python, especially if you run
applications that need to communicate with databases such as MS SQL
Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase
ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more,
that run on Windows or Linux machines.

By removing the need to install and configure ODBC drivers on the
client side, mxODBC Connect greatly simplifies setup and
configuration of database driven client applications, while at
the same time making the network communication between client and
database server more efficient and more secure.

For more information, please see the product page:

http://www.egenix.com/products/python/mxODBCConnect/



NEWS

mxODBC Connect 1.0.1 is a patch-level release of our new mxODBC Connect
product.

* More Robust

We have made the client and server more robust in case of communication
failures. Even if the client applications fail to shutdown the server
connection before exiting, the server will free up resources used by the
client on the server side and rollback transactions as necessary.

* More Platform Support

With the 1.0.1 release we are also providing much better platform
support for the mxODBC Connect Client: we have fixed a problem in 1.0.0
that prevented the installation of the pre-built clients on non-Linux
systems.

The mxODBC Connect Client can now be installed on most platforms
supported by Python, since it is written in a platform independent,
portable way.

The pre-built archives also make it possible to integrate the clients
into build system such as buildout (used in Zope and Plone) or other
distutils-based deployment systems.

* Ideal for Building Bridges

As a result, connecting from e.g. Mac OS X to an SQL Server database
has never been easier. You can even keep the data sources you already
have configured on your Windows machine and connect to them as if your
application were running on the database server itself.



UPGRADING

You are encouraged to upgrade to this latest mxODBC Connect release.
When upgrading, please always upgrade both the server and the client
installations to the same version - even for patch level releases.

Customers who have purchased mxODBC Connect 1.0 licenses can download
and upgrade their existing installations without having to purchase
new licenses or upgrades. The licenses will continue to work with
version 1.0.1.

Users of our stand-alone mxODBC product will have to purchase new
licenses from our online shop in order to use mxODBC Connect.

You can request 30-day evaluation licenses by visiting our web-site
or writing to sa...@egenix.com, stating your name (or the name of the
company) and the number of eval licenses that you need.

http://www.egenix.com/products/python/mxODBCConnect/#Evaluation



DOWNLOADS

The download archives as well as instructions for installation and
configuration of the product can be found on the product page:

http://www.egenix.com/products/python/mxODBCConnect/

Evaluation licenses for the server part are available free of
charge:

http://www.egenix.com/products/python/mxODBCConnect/#Evaluation

The client part of mxODBC Connect is always free of charge.

Which database adapter have you been using for the Zope database
connection ?

We've never had reports of missing data or anything the like from our
mxODBC Zope DA customers in all the years it has been in production
on Windows.

Perhaps you are facing database problems with the database that
originate in the way the database does row level locking ?

Or are you talking about ZODB conflict errors ?

I guess you're better off with storing your data in the ZODB if
you're looking for file copy based consistent backups.

I don't know of any RDBMS that would allow file copy based backups
from a running system while still maintaining consistency. At the very
least, the database system has to flush its buffers to the database
files, so you need special tools for the backup one way or another.

OTOH, nearly all database systems provide live backup tools
which create consistent backups of a running system.

It used to be fairly safe at one point (I think around Python 1.4),
but maintenance was then dropped and so it was deprecated later
on. The main module was called Bastion.py.

Right.

While some of them are fairly good at restricting
access to e.g. the file system or object system, they usually
lack protection against unlimited CPU and memory use.

A multi-threaded approach makes hard as well, since killing of
a thread often doesn't release the associated resources.

In a multi-process environment things are easier, since the OS
will take care of most of the monitoring and apply this at a
much lower level.

It was a lightning talk. I'm not sure whether those are online

... and that's good :-)

I think the only problem with PythonScripts is that they advertise
themselves as providing a secure way to run Python code (see the
help documentation) and that can potentially cause serious security
problems.

In my experience, attempts to create a sandbox that protects
sufficiently against unwanted resource usage are either too
restrictive and slow to make them useful or have problems
preventing DOS attacks.

It's usually a lot better (and more efficient) to use trusted
code only.

BTW: The reason why I had a look at these was that Chris Withers
mentioned at EuroPython that they are currently causing delays
in the Python 2.5 adoption (or at least are one of the reasons
for them).

The .encode() example will only trigger if the Python test suite is
installed in your Python version. Some distros move this into a
separate package, so if this is not installed, that particular
example won't work.

Please add a warning to be extra careful when enabling edit/create/modify
access to PythonScripts in the ZMI.

I really didn't have any intention of making your work harder than
it already is - I must admit that I wouldn't have thought of the
issue being that important.

OTOH, I do think that the PythonScript product will need some
more security audit, esp. since the restricted environment
safety belt checks are no longer being maintained in the Python
interpreter code and will likely go away completely for
Python 3.x.

It may be better to remove the PythonScript product altogether and
instead use ExternalMethods.

[Zope] Script (Python) insecure ?

[M.-A. Lemburg]

Hello,

after Chris Withers lightning talk at EPC 2008 I had a closer look
at the implementation of Python Scripts in Zope 2.11.

While I have not yet been able to break out of the restricted
environment without help from installed products, there are a few
denial-of-service attacks which can easily be deployed on sites
allowing adding Python Scripts to a user folder:

1. Attack:

Put this into a "Script (Python)" object and run it:

return 'kaboom'.encode('test.testall')

This results in a denial-of-service, since Zope will hang
running the Python test suite.

The reason for this is a problem in the way the encoding search
function works in Python 2.4. This was changed in 2.5 to no longer
allow searching for codecs outside the encodings package.


2. Attack:

Put this into a "Script (Python)" object and run it:

raise SystemExit

This shuts down Zope.

The Python Script environment should obviously catch such exceptions
and not let them propagate up the call stack.


I found the second attack rather surprising, as it doesn't require
deep knowledge about Python's interna.

 Ok, thanks. How do I deploy such a thing? I guess virtualenv then has
 to run by the one setting up his development sandbox? What files
 can/need to be in subversion? (I never used virtualenv before, only
 buildout).

 So my main question is probably: Is there a way to automate the
 process of installing and running virtualenv similar to what
 bootstrap.py does for buildout so that people do not need to care
 about the virtualenv part?


Use a clean custom built Python.

[Zope] ANN: eGenix mx Base Distribution 3.1.0

[eGenix Team: M.-A. Lemburg]

ANNOUNCING

eGenix.com mx Base Distribution

Version 3.1.0

  Open Source Python extensions providing important and useful
  services for Python programmers.


This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-mx-Base-Distribution-3.1.0-GA.html



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 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 - 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

All available packages have proven their stability and usefulness in
many mission critical applications and various commercial settings all
around the world.

* About Python:
Python is an object-oriented Open Source programming language which
runs on all modern platforms (http://www.python.org/). By integrating
ease-of-use, clarity in coding, enterprise application connectivity
and rapid application design, Python establishes an ideal programming
platform for todays IT challenges.

* About eGenix:
eGenix is a consulting and software product company focused on
providing professional quality services and products to Python
users and developers (http://www.egenix.com/).



NEWS

The 3.1.0 release of the eGenix mx Base Distribution has a number
of enhancements over the previous version 3.0.0. Apart from a few
minor bug fixes, it provides a few new features:

Some highlights:

* mxTools now has a new mx.Tools.dlopen() function which allow
  loading shared libraries explicitly and from a specific
  path. This allows working around problems with not being able to
  dynamically set LD_LIBRARY_PATH on Unix platforms.

* mxTools can be configured to expose a new API called
  mx.Tools.setproctitle() which allows setting the process title
  on Unix platforms.

* mxBeeBase comes with a new on-disk dictionary version called
  BeeFixedLengthStringDict, which allows using keys with embedded
  \0 characters.

* mxSetup, our Python distutils extension, can now build prebuilt
  archives that no longer require the "... build --skip ..."
  command to skip the build process.  The uninstall command now
  also works for prebuilt archives and the bdist_prebuilt command
  has been enhanced to be able to build pure Python distributions
  as well.

* mxSetup now also works together with setuptools to e.g. build
  and install the packages as eggs. Run setup.py with
  --use-setuptools to enable this support.

For a more detailed description of changes, please see the respective
package documentation on our web-site.

As always, we are providing pre-compiled versions of the package for
the most popular Python platforms. For all others, you can compile the
package from source using "python setup.py install".

Have you tried to just generate 25K users in an empty site and see what 
happens? It should take 15 about minutes to set up and write the code.


Members are stored in a dict, and the ZODB. They should be plenty fast.

Last week I wrote a tool that imported 10K lines of data from a csv file 
as dicts. It took about 2 seconds to read them from disk and save them 
in the ZODB. That is comparable.


Perhaps you don't have a problem?

 Hi everyone,

 I am happy to announce that the second Foliage sprint task is
 completed. Julian Bonilla, Graham Stratton and I worked on the
 outstanding issues on creating a functional version of the APIDOC,
 which comes with Zope.

 Thanks to Jens Vagelpohl, the static APIDOC is now available at:

 http://apidoc.zope.org

 I have also uploaded a TGZ archive to:

 http://download.zope.org/distribution/static-apidoc.tgz

 I hope that this development will spark renewed interest in the tool.
 In the future I plan to make more packages available in APIDOC and
 make it work with eggs. If you are interested, please let me know!


Great news !
Congratulations to you all !!

Basically everything is true. The time of www.zope.org as a software 
repository has gone. In earlier times zope.org has been the only Zope 
related site. Nowadays with the growth and Zope and a lot of new 
projects, projects moved out into different sites. zope.org is an 
official project of the Zope Foundation and there were some talks on 
relaunching zope.org - however I don't know about details and the 
current state. The new site is likely to become a small site 
representing the Zope platform  in the first place.



I used to be pretty active on the original Zope site. Then we got what 
we asked for, and it was migrated to Plone.


Then it got too cumbersome to work with, and I put all the new stuff out 
on my own site.


These days I use a mix of plone.org and my own site.

zope.org is pretty irrelevant to what I do these days. I believe it is 
so for many zope people.

 I assume you're generating long_description from a README.txt file or
 so. If you have docutils installed, you can render this file yourself
 using the rst2html script. It will show warnings and errors during
 the rendering. Fix those, and PyPI will happily render your reST as
 well.


You can do it like this :

 $ python setup.py --long_description > ld.txt

Now remove first line of ld.txt , it's a junk info, then :

 $ rst2html ld.txt > ld.html

Hi,
Would you know any genealogy product for Zope?
Is zope a tool for managing a big (20 members) of genealogy oriented 
group, which has over 150,000,000 entries in the genealogy tree?


It is now managed with about 20 servers and SQL databases but Zope might 
be a solution, isn't it?



It depends a bit on what kind of data is in the genealogy product.

If it is 150,000,000 of very similar data objects, it might be better 
stored in a relational database.


It would probably be relatively simple to create a small working 
product, to import some of the data and see how it pans out.

[Zope] ANN: eGenix EuroPython 2007 Presentations & Videos

[eGenix Team: M.-A. Lemburg]

  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.

[Zope] Interest in a one-day business conference for Python, Zope and Plone companies ?

[eGenix Team: M.-A. Lemburg]

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
Düsseldorf, 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.

[Zope] eGenix Partner Network (Pre-Announcement)

[eGenix Team: M.-A. Lemburg]

Hello,

we are currently looking into setting up a partner network of
companies interested and able to sell and support our products with a
more regional focus than we can deliver.

The idea is to provide customers with a closer and more direct contact
for first level support. Network partners should be able to do projects
using or based on eGenix products and maintain a proper customer
relationship in their native language.

If you are interested in joining the network, please contact us
or, even better, arrange a meeting at EuroPython or PyCon UK
with us to discuss the details.

We will be making an official announcement of the eGenix Partner
Network sometime after EuroPython:

The upshot of the dev team moving their time and efforts to zope 3 is

ABOUT

The mxODBC Database Interface allows users to easily connect
Python applications to just about any database on the market
today - on both Windows and Unix platforms in a highly portable
and convenient way.  This makes mxODBC the ideal basis for writing
cross-platform database programs and utilities in Python.

mxODBC is included in the eGenix.com mxODBC Distribution
for Python, a commercial part of the eGenix.com mx Extension Series,
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.

The package has proven its stability and usefulness in many mission
critical applications and various commercial settings all around
the world.

* About Python:
Python is an object-oriented Open Source programming language which
runs on all modern platforms (http://www.python.org/). By integrating
ease-of-use, clarity in coding, enterprise application connectivity
and rapid application design, Python establishes an ideal programming
platform for todays IT challenges.

NEWS

mxODBC 3.0 has received a large number of enhancements and supports
more ODBC drivers than ever.

Some highlights:

* mxODBC has been ported to Python 2.5.

* We've worked a lot on the Unicode support and made it more
  robust, especially on Unix platforms where the ODBC Unicode
  support has stabilized over the last few years. You can now issue
  commands using Unicode and exchange Unicode data with the database
  in various configurable ways.

* We've also added a methods to give you more control of the
  connections and cursors as well as the .callproc() method for
  calling stored procedures that mxODBC 2.0 was missing.

* Multiple result sets via the .nextset() are also supported, so
  working with stored procedures should be a lot easier now.

* Another highlight is the added support for Python's datetime
  module types and the option to use strings for date/time
  processing (e.g. to be able to use timezones in timestamps if
  that's supported by the database).

* Python's decimal module is now supported as well and it's possible
  to configure mxODBC to return Decimal types for numeric values.

* mxODBC 3.0 received full 64-bit support, so that you can run
  mxODBC (and all other mx Extensions) on e.g. AMD64 platforms.

* We've switched from the old distutils wininst installer to the
  new MSI installer for the Windows Python 2.5 build. This gives
  you a lot more options for automatic installs, including
  unattended installs.
  See http://www.python.org/download/releases/2.5/msi/ for details.

Note that in order to avoid confusion, we've decided to rename the
eGenix.com mx Commercial Distribution to eGenix.com mxODBC Distribution
with this release. The commercial distribution has always only contained
the mxODBC package, so this was an obvious step to clarify things for
our users.

As always we are providing pre-compiled versions of the package for
Windows, Linux, Mac OS X, FreeBSD and Solaris as well as sources
which allow you to install the package on all other supported
platforms.



DOWNLOADS

The download archives and instructions for installing the package can
be found at:

http://www.egenix.com/products/python/mxODBC/

IMPORTANT:
In order to use the eGenix mx Commercial package you will first
need to install the eGenix mx Base package which can be downloaded
from here:

http://www.egenix.com/products/python/mxBase/



UPGRADING

Please note that mxODBC 2.0 does not support Python 2.5 on 64-bit
platforms due to the Py_ssize_t changes in the Python C API.

You are encouraged to upgrade to the new mxODBC 3.0 release, if you plan
to deploy on 64-bit platforms and use Python 2.5 as basis for your
applications.

[Zope] Re: a question about aq_base

here: http://docs.neuroinf.de/programming-plone/ate we can read:

Usually, it is a bad idea to use "aq_base" in Zope applications

You should carefully examine the context of the code fragment above.
Maybe, the context is one of the rare situations where "aq_base"
is called for...


Why is it rare?

I often need to check if an object has a certain attribute. Getting 
aquisition into the mix is a bad idea there.::


name = getattr(obj, 'name')

Is a lot different than

name = getattr(obj.aq_base, 'name')

In the first example you don't know if the name attribute is an aquired 
object or an attribute on the actual object. Which can make for 
uncontrollable results.

Yes so please stop arguing as if we are arguing anything but opinions.


read the corresponding posting on Zope 2+3 by Jim Fulton 
published after the last PyCon. There is no word of phasing out Zope 2.


I believe it will happen a lot faster than you think. New versions of 
Plone will use it exensively, so there will be a lot of new developers 
from that comunity. Which is pretty big. That will drive the shift forward.


I know plenty of Plone developers, and I don't recall that any of them 
yearn to stay in Z2 after having tried Z3. Quite the opposite.



Btw. I don't see any reason to use words like 'drivel' and 'bullshit'.

It is rude and counterproductive. And I don't recall that I have been 
rude on this list in general or to you specifically.


I am not trolling I just gave a new developer what I believe is good advice.

This is the first I have heard about Zope 2 being phased out...


Well .. get used to it then ;-)

Z2 will keep on being maintained until it is replaced by Z3. The goal of 
the zope developers is not about keeping Z2 and Z3 running for as long 
as possible. Only for as long as necessary.


Z2 is still being maintained, and will be for a long time. But the 
development is all moving in the direction of Z3.


Read the changelog of the latest Z2 releases. They are practially only 
about bugfixes and Z3 integration. Core Zope 2 development has 
practically grinded to a halt. New developments are taking place in Zope 3.



How is that not an outphasing?

That's questionable. Answers like this only add to a certain FUD factor 
out there about Zope2 being thrown out shortly.


You don't have to throw out Zope 2 to start using Zope 3. Just ignore 
Zope 2 and get on with it.



If you need features that are in Zope 2 but not in Zope 3, you are 
better of using a framework like Plone.


Hell no. Trying to throw a complete newbie not just into developing with 
Zope, but developing with Plone on top of Zope is, IMHO, insane. Not 
only do you need to learn Zope, you also need to learn the various Plone 
programming paradigms.


That is why I recommended Zope 3 as the first choice. Zope 3 is clearly 
ready for production. In many areas it is allready far better than Zope 2.


I don't understand why it is better for a newbie to learn Zope 2 than 
Zope 3? Zope 2 has so many warts, and is a dead end.



That's just bad advice, unless someone truly 
wants those portal-like functionalities in Plone.


And if they don't, they should use Zope 3.


I did not say that Zope 2 was useless. I still spend most of my time 
working on Plone based projects.


This is a case of professional "blinders". You've been working with a 
specific combination for years so these things come easy to you. The 
problem is you don't seem to see that there is healthy life outside of 
Plone. Or outside of Zope 3, for that matter.



Well the problem is that Zope 2 was never easy for beginners either. And 
by now it is starting to get phased out for Zope 3.


This is not something I make up. It is the stated goal for all the Zope 
2 based projects I have heard about. They call it slowly migrating to 
Zope 3, but it really is the same goal!


This will take years. But it is happening. Eg. any new development in 
Plone will be in Zope 3. At least afaik.

[Zope] Using property() function in Zope 2.8

[Max M]

I needed to dynamically generate local roles for an Archetypes based 
content object today.


Different layers in my Plone stack breaks all rules and reads the 
__ac_local_roles__ variable directly, instead of calling get_local_roles()


So to maximize the compatibility between Zopes zmi and Plones local 
roles management I wanted to make '__ac_local_roles__' a property with 
setters and getters.


My AT class was based via a few hops on:

'from ExtensionClass import Base'.

And as far as I understand from the release notes Zope 2.8.x should use 
extension classes based on new style classes. So the property function 
should work.



This code below works in plain Python. But when I add them to my zope 
class, and run the tester() method I get an "Attributer Error: 
__ac_local_roles__"


Any ideas/comments?



# -*- coding: latin-1 -*-

class PropTest:

def get__ac_local_roles__(self):
return self.__mxm__ac_local_roles__

def set__ac_local_roles__(self, value):
self.__mxm__ac_local_roles__ = value

def del__ac_local_roles__(self):
del self.__mxm__ac_local_roles__

__ac_local_roles__ = property(get__ac_local_roles__,
  set__ac_local_roles__,
  del__ac_local_roles__,
  "Local roles on object")

def tester(self):
return self.__ac_local_roles__


if __name__ == '__main__':

p = PropTest()
p.__ac_local_roles__ = 'working'
print p.tester()

Hey David,

Cool, thanks so much for volunteering to provide all the resources,

problems that entails.


Oh? What's that? You weren't volunteering?



Personally I have not visited zope.org for a few years for anything 
other than releases. And I am a long time pro developer.


It seems pretty obvious these days that having a one-shop zope.org site 
is too ambitious. Perhaps even wrong guided.



I wouldn't even know what should be on it. Zope 2 development mostly 
means Plone these days. Plone has a great site already, so no reason to 
do to much about that.



Pure Zope 3 is in even less use than pure Zope 2.

The exciting stuff is going on in Five and 2-3 integration. But why the 
heck make a site about that?


You could say that zope has been beaten by its own success.


The only sensible approach I can see is to make a new zope.org with 
releases, installation guides etc. It should also showcases the great 
cms/applications that are build on top of it. With links to those sites.


On those individual sites there are lots of documentation, product 
releases programming tricks etc.



Eg. I develop in Plone, and practically all I knew about programming in 
pure Zope 2 is useless now that I am using UML/AT/AGX in Plone. It's 
like assembly language to a python programmer. I assume that it is the 
same for other frameworks.


Having a 'Products' section on zope.org probably doesn't even make sense 
anymore. It is simply to low level.



Drop all the old documentation and move it to old.zope.org. Just in 
cases there is a nugget somewhere.

Greetings to all,

my company is searching for a tool capable of producing good quality pdf's from 
page templates or documents on the fly.
This tool should somehow integrate with Zope. It could be Zope/Plone product, 
python script or even shell script invoked by Zope. It can be commercial (and 
probably will be).
I've searched the net, but found nothing that would met this requirements:
* professional css conversion: pdf should look almost exactly like source 
document, all css properties should be handled
* it should omit silently html elements, that are not supported (e.g. flash 
objects, applets) without crash or error
* links should be active (clickable) in pdf
* conversion of html forms to pdf forms would be nice to see
* conversion from flash objects or java applets to static images (somehow) 
would be nice to see too
* even putting flash objects into pdf was considered (i'm suspecting latest pdf 
format handles build-in flash, since adobe bought macromedia some time ago)

Every help that i can get would be appreciated.



With all those requirements I believe that every help you can get will 
be expensive ;-)



Many of your wishes are huge tasks. A project like that could easily run 
into hundreds of hours.


Building a custom tool using reportlab is probably the most feasible 
approach.



But most likely you should forget about Zope Plone compatibility and 
just find a tool that can convert all html to pdf, and find one that can 
be automated. Then make sure that your Plone output can be converted via 
that tool.


This turned up many interesting tools:

OK, thanks. I hope you'll agree though that the three excerpts below from

With a 4 GB machine that is probably not a problem. You can usually run

I think these questions are very ZOPE RELATED since I asked them in a

Eh ... it doesn't become zope related because you ask it in a Zope 
group. Do you also ask how to write books on a Microsoft Word list?




I'm asking about Zope user/administrator experience related to Zope
use on a quad machine!!!

Of course if some1 tells me how to do it using OS related stuff this
is STILL Zope related!


Assigning a process to a cpu is a general os problem, and not really 
related to zope. Zope is just another process.


eg: http://www.google.com/search?q=cpu+affinity

plone.org is running on a dual cpu box, with one zeo and a zeo client, 
so clearly it can be done.




Hey... but thank you Jens for spending all that time writing an email

You can set up zope with zeo and then assign 3 zeo clients on different 
processors that shares the zeo server.


That should get you a lot of the way.

[Zope] Method cache (Memoize) for Zope

[Max M]

Has anybody written a Memoize-like decorator for Zope?

I imagine that it could be a nice feature to have a standard decorator 
for Zope that would cache results in a _v_ volatile variable.


I usually do it a bit like this::

def _cache_it(self, meth, *args, **kwargs):
cache_name = '_v_%s' % meth.__name__
if not hasattr(self, cache_name):
result = meth(*args, **kwargs)
setattr(self, cache_name, result)
return getattr(self, cache_name)


def _some_function(self):
# do expensive calculations and return result
return 42


def some_function(self, *args, **kwargs):
"Returns cached values"
return self._cache_it(self._some_function, *args, **kwargs)

But I guess that there must be someone who has allready written a more 
generic way to do it via generators?

If you only need to read from some native python objects, you can make a 
simple wrapper. You can wrap a set() in this class and return it from 
python.


_marker = []

class Zello:

If you try to view attributes on simple Python objects you get a

error. This is pretty simple to fix in your own objects by setting:

__allow_access_to_unprotected_subobjects__ = 1

For some built in objects you cannot do this. This class just puts a
transparent wrapper around such objects::

wrapped = Zello(datetime(2005, 10, 12))

So you can write this zpt code:



If you wrap a Zope object with it, you basically remove all security
checkcs. So don't do that.

__allow_access_to_unprotected_subobjects__ = 1

def __init__(self, obj):

[Zope] JSON for Ajax applications

[Max M]

I don't know how many has seen this, but it's pretty cool.

JSON (JavaScript Object Notation) is a lightweight data-interchange format.

http://www.crockford.com/JSON/index.html

It is used for Ajax applications to transfer data instead of xml. It 
uses repr() versions of standard python objects like dicts, lists, 
string, numbers etc. to transfer data.


It is really simple to generate for Python programmers, so it is very 
simple to use in Zope too.

You must write a script that converts any property on any object in your 
site that is latin-1 to utf-8.


So first find all objects you use. See what types they are.

Find all text and string attributes on those opjects.

Write a function that converts from latin to utf and run that on every 
object.


The hard part will be finding all the attributes, but perhaps you can 
write a method that can help find those properties for you using 
introspection.

It's better coded, easier to understand, more futureproof and probably 
better documented.
