EuroPython news update april 27
by Martijn Faassen 27 Apr '04

27 Apr '04

Hi there, Back again with news about EuroPython. The talk submission deadline has now passed, which means we can give you a little preview of our program: http://www.europython.org/conferences/epc2004/info/talks/acceptedTalksOverv… Note that this is not by far the complete program, just a preview. The Zope track for instance hasn't any accepted talks yet at the time of this writing, while in reality it's shaping up to be as big as last year (i.e. 3 days of Zope related talks). If this overview suddenly prompted you to register with the conference, please note: the early bird deadline closes may 1st, which is next saturday! If you wait until later, you'll pay more. More about EuroPython, including how to register, can be found here: http://www.europython.org Hope to see you at EuroPython! Martijn

Middleware'04 Call for Tutorials
by Middleware 04 26 Apr '04

26 Apr '04

Call for Tutorials to be held in conjunction with Middleware 2004 ACM/IFIP/USENIX 5th International Middleware Conference Toronto, Ontario, Canada October 18th - 22nd, 2004 http://www.eecg.utoronto.ca/middleware2004/ Overview Requirements for faster development cycles, decreased development efforts, greater software reuse, and better end-to-end control over system resources are motivating the creation and use of middleware systems and middleware-based architectures. Middleware is systems software that resides between the applications and the underlying operating systems, network protocol stacks, and hardware. Its primary role is to functionally bridge the gap between application programs and the lower-level hardware and software infrastructure in order to coordinate how application components are connected and how they interoperate. Furthermore, middleware enables and simplifies the integration of components developed by multiple technology suppliers. In this sense middleware systems are sets of services and abstractions that facilitate the development and deployment of distributed applications in heterogeneous, distributed, computing environments. Next-generation distributed applications and systems will increasingly be developed using middleware. This dependency poses hard challenges, including latency hiding, masking partial failures, information assurance and security, legacy integration, dynamic service partitioning and load balancing, and end-to-end quality of service specification and enforcement. To address these challenges, researchers and practitioners need to discover and validate techniques, patterns, and optimizations for middleware frameworks, multi-level distributed resource management, and adaptive and reflective middleware architectures. Following the success of past conferences in this series, the 5th International Middleware Conference will be the premier event for middleware research and technology in 2004. The scope of the conference is the design, implementation, deployment, and evaluation of distributed system platforms and architectures for future computing and communication environments. Highlights of the conference will include a high quality technical program, tutorials, invited speakers, poster presentations, and workshops. The proceedings of Middleware 2004 will be published as a Springer-Verlag volume in the Lecture Notes in Computer Science Series. For paper formatting instructions see the Springer-Verlag guidelines for authors. All papers should be no more than 20 pages in length. For more detailed submission instructions, please visit the Middleware 2004 web site. Topics of Interest The topics of this conference include, but are not limited to: Distributed real-time and embedded middleware platforms Reliable and fault-tolerant middleware platforms Support for multimedia in middleware platforms Middleware for Grid computing Novel quality of service architectures and evaluation techniques Event-based, publish/subscribe and messaging-oriented middleware platforms Open architectures for reconfigurable middleware Adaptive and reflective middleware Aspect-oriented middleware Generative programming techniques for middleware development Middleware protocols and services for information assurance and security Formal methods and tools for reasoning about middleware systems and services Management and use of component-based systems in distributed environments Applications of middleware technologies, including telematics, command and control, avionics, and e-commerce Novel paradigms, APIs, and languages for distributed systems Integration of middleware with model-integrated computing architectures, such as the OMG's Model Driven Architecture (MDA) Extensions and refinements to RM-ODP, CORBA, J2EE, .NET, etc. Impact of emerging Internet technologies and standards on middleware platforms Integration of middleware platforms with Web services and Java technologies Distributed systems management and interactive configuration and development tools Issues of scalability in existing and new distributed systems platforms Engineering distributed systems in heterogeneous and mobile networks Middleware for ubiquitous and mobile computing Organization General Chair: Steve Vinoski (IONA Technologies, Inc.)

[ANN]PyCrash-0.4pre2 released
by Carmine Noviello 25 Apr '04

25 Apr '04

Hi, a new version of PyCrash is released with new features and improvement.You can download it at: http://sourceforge.net/project/showfiles.php?group_id=98026&package_id=1110… What's new in this release: * Added a new method to PyCrash class, forceDump(), that forces the creation of the crash dump, if an exception is raised. forceDump() can be very useful when an exception hasn't reached the top-level, but the user wants the same to make a dump of the application context. * Starting from this release, by default, PyCrash doesn't start exception tracing automatically. User must invoke the enable() method to start tracing, and can use the disable() method to stop tracing in every moment. * Now the getEncryptedCrashDump() method of utils.Encrypt.EncryptedPyCrash class is deprecated, and it will be no longer supported starting from PyCrash-0.4 release.Use instead the getCrashDump() method. * Added a new class HTMLPyCrash, in the pycrash.util module, which converts the crash dump in HTML format rather than XML. The generated HTML dump is based on CSS, so the developer can define custom CSS to arrange the output. There is also a new script in the util subdir, named pucrash2html.py, which converts PyCrash file in HTML format. You can see an example of the output generated by the HTML dumper here: http://pycrash.sourceforge.net/test-pycrash.html Enjoy! _______________________________________________________________________ About PyCrash Project: PyCrash is a Run-Time Exception Dumper which handles uncaught exceptions during the execution of Python programs and collects information about the program context. PyCrash can be very useful in report bug information, because the programmer can easily analyse the program execution context of the crashed application. Major information collected by PyCrash in the crash dump is: - Information about operating system, Python and Python Standard Library version and general information about the program that is crashed (e.g., program name and version, time at witch program started and ended, and so on) - Information about the uncaught exceptions, like the exception type, the context (namely method name) in which the exception occurred and the exception value - General information about variables state - Information about the stack of each thread, like the list of stack frames, the variables value in each stack frame, and so on - General information about source code, like variable and function position in source file that can be useful for the programmer to find quickly bugs in source tree The format of the crash dump file generated by PyCrash is XML, so the programmer can easily read this file to understand why the program is crashed. Now, is also available a GUI browser, named PyCrash Viewer, which allows developers to analyze quickly and easily PyCrash crash dump files in a graphical manner. * Starting from next version, we'll try to document all the PyCrash API More information can be found at: http://www.pycrash.org Thanks! <P><A HREF="http://www.pycrash.org";>PyCrash 0.4pre2</A> - a crash handler for Python written applications.

[ANN]: 'tconfpy' 1.181 Released
by Tim Daneliuk 24 Apr '04

24 Apr '04

'tconfpy' 1.181 is released and available at: http://www.tundraware.com/Software/tconfpy/ This is the first public release of the program. A FreeBSD port is also being submitted. 'tconfpy' is an advanced configuration file parser and validator for Python programs. By using 'tconfpy', Python programmers can provide their users with an external configuration file for setting program options, defining defaults, and so on. 'tconfpy' offloads the responsibility for parsing and validating a configuration file from the main application. The Python programmer need only deal with the results and any errors or warnings generated during the parsing process. 'tconfpy' recognizes a rich configuration language and provides a number of sophisticated programming features including: - The ability to breakup large configurations into smaller pieces via the '.include' directive. - Support for string substitution and concatenation throughout the configuration file via string variables. Variables may be locally declared, a reference to a symbol already in the symbol table, or a reference to an environment variable. - A complete set of conditional directives for selective processing of configuration options. Both existential ("If variable exists ...") and comparison ("if string equals/does not equal string ...") forms are provided, as is an '.else' directive. - The ability to instantiate program options prior to reading a configuration file and make them mandatory by declaring those options as Read-Only. - Optional type validation to ensure that a user enters a value appropriate for boolean, integer, floating point, string, or complex data. - Optional value validation to ensure that a configuration option is either within a specified range or one of an enumerated set of possible values. For configuration options which are string types, 'tconfpy', can optionally specify min/max string lengths and enumerate a set of legitimate regular expressions that the string must match. - The ability to define an arbitrary number of lexical namespaces. - The ability to use the various features of 'tconfpy' as a pre- processor for any other text (including source code for other programming languages and Python itself) via the '.literal' directive. - An optional debug capability which returns detailed information about each line parsed. - Includes a test driver program for learning how to program with 'tconfpy' and for debugging and testing your own configuration files. - Comes with over 30 pages of documentation including a Programmer's API Reference and a User's Guide to the 'tconfpy' configuration language. Documentation is provided in several formats including Unix 'man', Plain Text, html, pdf, and Postscript. 'tconfpy' is a Pure Python module and is platform-independent. It should work identically on any platform on which Python runs. ---------------------------------------------------------------------------- Tim Daneliuk tundra(a)tundraware.com PGP Key: http://www.tundraware.com/PGP/

ANN: Atox 0.5 released
by mlh＠furu.idi.ntnu.no 23 Apr '04

23 Apr '04

What is it? =========== Atox is a framework for automated markup. With it one can quite easily write custom scripts for converting plain text into XML in any way one wishes. Atox is normally used as a command-line script, using a simple XML language to specify the desired transformation from text to markup, but it is also possible to build custom parsers using the Atox library. The name (short for ASCII-to-XML) is inspired by such UNIX tools and system functions as atops and atoi. What can it do? =============== With Atox you can write quite general parser that create XML from plain text files, using a special-purpose format language somewhat reminiscent of XSLT. You can also include XSLT fragments in your format description, to use transformations in concert with the Atox markup process. The examples in the distribution demonstrate how you can use Atox to: - Mark up a (relatively simple) technical document (the Atox manual); - Mark up code blocks only through indentation; - Nest lists through indentation - Discern between different indentation "shapes" (e.g. a block quote versus a description list item); - Transform simple LaTeX into XML; - Add XML "syntax highlighting" to Python code; - Mark up screenplays or stageplays, largely based on indentation; - Mark up simple fictional prose; - Mark up simple tables. What's new in 0.5? ================== These are the changes I've made: - Fixed some bugs. - Added support for XSLT fragments in Atox format files. - Added support for non-greedy repetition. - Added several new options to the configuration system. Split input and output encoding and made UTF-8 the default output encoding. Where can I get it? =================== Atox is hosted at SourceForge (http://atox.sf.net) and the current release (0.5) is available for download via its project page (http://sf.net/projects/atox). The Small Print =============== Atox is released under the MIT license. It comes with no warranty of any kind. Also, even though the current version works well, and the project is currently (as per early 2004) being actively developed, there is no guarantee of continued support. What you see is what you get. -- Magnus Lie Hetland "Wake up!" - Rage Against The Machine http://hetland.org "Shut up!" - Linkin Park
