Bonsoir Frédéric & Mike,
Je fais partie des personnes qui ont assisté à la reunion sur Python et
je vous félicite pour votre exposé sur python.
Je voulais juste vous signaler que le projet jython ne devrait plus
rester en standby car Brian Zimmer a reçu une bourse de la PSF pour
poursuivre le développement de jython. Son projet s'appelle
"MovingJythonForward" et on peut le trouver ici:

Bonsoir Frédéric & Mike,

Zimmer
Moving Jython Forward
Proposal Submitted to Python Software Foundation
Fall 2004 BrianZimmer
Abstract
Jython is a popular implementation of the Python programming
language targeted for the Java Virtual Machine. It has a very active
user community evident from the number of books published, technical
articles submitted and constant references to it in articles and blogs.
However, it continues to suffer a stagnant growth that can be
attributed to a limited and often quiet development team. While other
languages such as Groovy are making headlines with their increased
release cycles and features Jython has not kept pace. The current
release, 2.2b, is unacceptable given the growth of the C
implementation. This proposal is interested developing many of the
missing features from the C implementation of Python and documenting
the current architecture to enable growing the current development team
and moving Jython forward.
Proposal
This proposal will put an end to the constant Jython-Users question,
“Is Jython development dead?” It will address many areas of Jython
development but the schedule may require refactoring to better suit the
needs and requirements of the Jython user community.
New-Style Classes February 2005 (40 hours)
One of the primary missing features in the current version of Jython
is the implementation of new style classes. Samuele Pedroni has done a
significant amount of work to implement this crucial feature but it is
incomplete. This proposal aims to complete the development through
collaboration with Samuele and provide this critical new addition to
Jython.
Close bugs & apply patches March 2005 (20 hours) This proposal
will close out critical bugs reported on the sourceforge tracker as
well as apply community provided patches.
Jython 2.[3-4] Alpha April 2005 (10 hours)
The completion of the new-style class integration and the fixing of
critical bugs will culminate in the release of the first alpha for the
improved code base. This will also include the creation of repeatable
build, deployment and installation scripts to facilitate future
releases.
Improved Java Integration May 2005 (80 hours)
Perhaps Jython’s strongest feature is its tight integration with
Java and the JVM. While the Python language garners a tremendous
following numerous Jython users come from Java, turning to Jython to
ease some of the complexities of Java and increase developer
productivity. This proposal will address the following issues:
Support for boolean type
JythonC integration into standard interpreter compiler
PEP 302 (New Import Hooks)
Logging (PEP 282, there exists a patch proposal for integration
with Log4J)
Flexible DataType
marshalling from the Jython runtime to Java runtime
sets module java.util.Set
datetime module java.util.[Date|Calendar]
User-defined types
A common issue going forward will be the continued need to enable
the Jython source to run on numerous versions of the JDK. Jython cannot
run on the 1.5 version of the JVM because of changes to both bytecode
and the core language (assert). This limitation will be fixed.
Jython 2.[3-4] Beta June 2005 (10 hours)
Fix any outstanding issues found in the Alpha and incorporate the
tighter Java integration features. The resulting work will be released
as a Beta candidate.
Jython 2.[3-4] Final July 2005 (10 hours)
Release a Jython Final.
Missing Modules August 2005 (40 hours)
The C implementation of Python has introduced a number of useful
modules and their absence complicates running the same Python source on
the C and JVM implementations. It is proposed the following modules be
written:
sets
select
datetime
Community prioritization will dictate the remainder, if any, of the
modules to be implemented. The submission of completed modules will be
greatly encouraged.
Missing Built-ins October 2005 (80 hours)
A number of built-ins are missing as well methods core classes have
grown since 2.1. Some of the missing features have been documented in
the whatsnew lists available with each new release.
http://www.python.org/doc/2.2.1/whatsnew/whatsnew22.html
http://python.org/2.3/highlights.html
http://python.org/2.4/highlights.html
The omissions capable of being implemented in 100% Java will be
completed and the unit tests provided for the C implementation
confirmed to pass.
Jython 2.[3-4]+ Beta October 2005 (10 hours)
Jython 2.[3-4]+ Final November 2005 (10 hours)
Documentation Ongoing
While the Python programming language is well documented the
internal workings of the Jython code base remains relatively poorly
documented. This proposal includes creating a developer document that
includes an overview of the Jython runtime and how it works as well
providing a style guide and coding standard. The current code does not
have a consistent style, which has created issues for a distributed
development team working with different IDEs and platforms. These
inconsistencies will be addressed.
Recruitment of
New Developers
In addition, and perhaps most importantly, is facilitating the
growth of the development team. This can be accomplished by actively
pursuing through the mailing lists and bug reports individuals who have
already expressed interest in developing Jython. The successful
addition to the Jython code base of a significant patch or new feature
will enable the submitter to be added to the development team and have
CVS commit privileges if so desired. This should ensure the growth of
the Jython development team and perhaps revitalize its activity. Budget
The funding will be compensation for time spent as well as the
resources to purchase an additional machine to allow for more
productive development. The breakdown of the hours required and rate
proposed for each task is available in the following table:
New-Style Classes Feb-05
Close bugs & apply patches Mar-05
Jython 2.[3-4] Alpha Apr-05 ?
Improved Java Integration May-05 ?
Jython 2.[3-4] Beta Jun-05 ?
Jython 2.[3-4] Final Jul-05 ?
Missing Modules Aug-05
Missing Built-ins Oct-05 ?
Jython 2.[3-4]+ Beta Oct-05 ?
Jython 2.[3-4]+ Final Nov-05 ?
The payments for this grant will be made on the successful
completion of each delivery of three releases: April 2005, July 2005
and November 2005.
Summary
Jython has long held the torch for being the most complete and
featurerich language other than Java to run on the JVM. It would be a
loss for so much work to have gone into the Jython project only to let
it atrophy.
Qualifications
I am currently a Jython developer with commit status at sourceforge
as well as the author of the popular DB API implementation, zxJDBC. I
have been the technical reviewer on two Jython texts, Jython Essentials
and Jython for Java Programmer, as well as have answered numerous
questions both privately and publicly on developing with Jython. I have
been using the Python programming language since 1996 on various
platforms, such as NeXTSTEP, OS X, Linux and Windows. I am also a
fulltime Java developer and have a long history with releasing quality
Open Source software that others and I have used in development and
production environments. I believe I have excellent qualifications to
continue the development of Jython and further promote the use of the
Python language.
