ANN: SimPy 1.6 released
by kgmuller 11 Jun '05

11 Jun '05

We are happy to announce the release of SimPy 1.6. Background: ----------- SimPy is a process-based discrete-event simulation language based on standard Python and released under the GNU LGPL. It provides the modeller with components of a simulation model. These include processes, for active components like customers, messages, and vehicles, and resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics. A GUI framework for simulations is included, as is plotting of results. SimPy can be downloaded from the SimPy web-site: http://simpy.sourceforge.net. The new version: ---------------- Release 1.6 is a new production version of SimPy. It adds two new commands for modelling reneging (processes leaving a queue for a resource before acquiring the resource) to the SimPy API: - 'yield (request,self,resource),(hold,self,timeout)' for timeout-based reneging - 'yield (request,self,resource),(waitevent,self,list_of_events)' for reneging triggered by one out of a list of events Two models showing the use of these statement forms are included in the distribution. The SimPy Manual and the Cheatsheet have been restructured and edited significantly for greater clarity. SimPy 1.6 runs SimPy 1.5.x. scripts unchanged. Download, experiment and enjoy! Any feedback is welcome! Klaus G. Muller Tony Vignaux --------------------------------- PS: Want to know more about SimPy?

ANNOUNCE: twill v0.7.1, scriptable Web testing.
by C. Titus Brown 09 Jun '05

09 Jun '05

ANNOUNCING twill v0.7.1. twill is a simple Web scripting language built on top of Python and John J. Lee's 'mechanize'. It's designed for automated testing of Web sites, but it should prove useful for anybody who needs to interact with Web sites (especially those using logins and cookies) on the command line or via a script. twill is a reimplementation of Cory Dodt's PBP. A twill script looks like this: # go to the /. login page go http://slashdot.org/login.pl # fill in the form fv 1 unickname test fv 1 upasswd test submit # ok, there's no such account ;). show error HTML. show --- This is the second public release of twill, version 0.7.1. (Tagline: "Most of the obvious bugs have been fixed.") I'm still looking for general feedback on usability, as well as suggestions on additional use cases. Download directly here: http://darcs.idyll.org/~t/projects/twill-0.7.1.tar.gz Documentation is online at http://www.idyll.org/~t/www-tools/twill.html --- Miscellaneous details: twill is implemented in Python and uses pyparsing and mechanize. In addition to the existing simple command language, twill can easily be extended with Python. twill also provides a fairly simple and well-documented wrapper around mechanize. twill scripts can be recorded with maxq, although scripts may require some hand tweaking at the moment. See the twill documentation for more information. twill does not understand JavaScript, I'm sorry to say. --- Notable bug fixes and features: * file upload & HTTP basic authentication; * submit w/o submit buttons now works; * better error reporting; * 'quiet', 'interact after scripts', and 'fail-immediately' command-line options. * '-' <== stdin on command line.

ANN: PyDO-2.0a3 released
by Jacob Smullyan 09 Jun '05

09 Jun '05

I'm pleased to announce the release of PyDO-2.0a3, the fourth and probably last alpha in this series. What's New ---------- * By popular demand, the package name has been changed (for the last time!) to "pydo". * PyDO now supports optional introspection of table columns and unique constraints at runtime, and can optionally cache the data found to disk. * drivers for mssql and oracle have been added. * a new function, ``fetch``, for performing joins -- or more generally, obtaining potentially multiple PyDO objects and other data at once in a single query -- has been added, and facilities with a similar purpose in the previous alphas have been removed. * a number of bugs have been squashed. Acknowledgements ---------------- This release contains substantial contributions from Jonathan Ellis, Tim Golden, and Hamish Lawson. Thanks all! What it is ---------- PyDO is Drew Csillag's ORM (Object-Relational Mapper) database access library for Python that facilitates writing a Python database access layer. PyDO attempts to be simple, flexible, extensible, and unconstraining. PyDO 2 is a rewrite of the 1.x series distributed with SkunkWeb. It has several enhancements: * PyDO can now be used in multi-threaded or twisted-style asynchronous sitations, with or without a customizable connection pool. * PyDO objects are now dict subclasses, but also support attribute access to fields. * Projections -- subsets of the field list of a super-class -- are now supported by the PyDO.project() method. * Table attributes are now declared in a more concise way. * PyDO2 supports runtime table introspection. * Overall, the API has been tightened and the code restructured. It also has several limitations: * PyDO 2 is still alpha code. Bugs should be expected, and the API is not guaranteed to be stable. * PyDO 2 requires Python 2.4 or later. PyDO 2 currently supports PostgreSQL, MySQL, Sqlite, MSSQL, and Oracle, and support for other databases is planned. PyDO is dual GPL/BSD licensed. The source tarball is available at SkunkWeb's berlios site: https://developer.berlios.de/projects/skunkweb/ or, more directly: http://download.berlios.de/skunkweb/PyDO-2.0a3.tar.gz Questions pertaining to PyDO can be addressed to the SkunkWeb mailing list at sourceforge: http://lists.sourceforge.net/lists/listinfo/skunkweb-list Cheers, js -- Jacob Smullyan

[ANN] SMC - State Machine Compiler v. 4.0.0 for Python
by rapp＠acm.org 08 Jun '05

08 Jun '05

SMC - The State Machine Compiler v. 4.0.0 Requires: Java 1.4.1 SE (Standard Edition) or better. Download: http://sourceforge.net/projects/smc Home Page: http://smc.sourceforge.net Why use Python? You know why - powerful, flexible, simple and very capable. Why use finite state machines (FSMs)? For the exact same reasons. Computing has long since moved beyond a single process, a single processor and single computer programming. Your application lives in a distributed world with asynchronous events, I/O and timers. Objects together with FSMs can handle this difficult world in a robust and efficient manner. An object's encapsulated FSM tracks the object's current state. The current state defines how the object should respond to an event. ================================================================= What is SMC? ================================================================= SMC takes a state machine description (stored in a .sm file) and generates State pattern classes in a target language (C++, Java, Tcl, VB.Net, C# and Python are currently supported). SMC is a console-based app written in Java which means SMC can run anywhere Java (1.4.1 or better) can run. The download package includes an example directory showing how SMC can used with C++, Java, Tcl (requires [incr Tcl] package), VB.Net, C# and Python. The examples range from trivial to GUI apps. SMC generated code is trivial to hook into existing Python applications: + SMC does not change your code or require you to change your code's logic. + SMC does not require that your class inherit or implement any SMC class. + SMC does not use state transition arrays or switch statements. An object simply instantiates the FSM and passing in its "self" to the FSM constructor. SMC is a mature software tool: 5 years old, in use around the world and used in production software for the telecommunications and financial exchanges. SMC generates code for C++, C#, Java, Tcl, VB.Net and now Python. It is an active open source project with new languages and features regularly added. ================================================================= How can I learn more? ================================================================= At http://smc.sourceforge.net. You can access the SMC Programmer's Manual there as well. While you're there, check out the SMC demo applet at http://smc.sourceforge.net/SmcDemo.htm. ================================================================= Where can I get it? ================================================================= SMC and the Programmer's Manual can be downloaded from http://sourceforge.net/projects/smc. You can also use this website to: + Ask questions (via the Public Forum's Help discussion) + Submit a bug. + Join a mailing list. + Access SMC documentation. + Access SMC's source code in the CVS repository.
