spyce v1.3.11 released
by Rimon Barr 07 Jul '03

07 Jul '03

Spyce v1.3.11 released on 7 July 2003 SPYCE is a server-side language that supports simple and efficient Python-based dynamic HTML generation. Those who are familiar with JSP, PHP, or ASP and like Python, should have a look at Spyce. Its modular design makes it very flexible and extensible. It can also be used as a command-line utility for static text pre-processing. Get it at: http://spyce.sourceforge.net Important changes since v1.3.10: - parser rewritten; compile times are now 2-6x times faster! (i.e. if you use CGI, the command-line interface, or frequently modify files during development, you'll greatly benefit from this release) - daemon mode for spyce webserver - exposed functionality for integration with Coil MVC framework - miscellaneous user-requested fixes Enjoy, Rimon. Change log: v1.3.11 user request: daemon webserver mode fix: mod_python flush problem performance: rewrote tokenizer/parser - no longer using clusmy parser generator package - still pure python, compilation times between 2-6x faster user request: expose functionality to define spyceProcess function with arbitrary parameters, and pass in parameters... helps Coil framework with Spyce integration fix: spyce webserver not performing path manipulations correctly on Windows fix: spyce.mime file not copied for .rpm and Windows installers v1.3.10 Default development configuration changed to: Apache 2.0.40 and Python 2.2.x Release testing will be performed: both on Linux and Windows under CGI, FastCGI and mod_python Other versions of Apache and Python should continue to work, but will not be tested. I am depending on user feedback to catch any errant bugs under these older configurations. fix: spyceWWW properly deals with directory URLs that don't end in '/' fix: request.getpost1/postget1() now accept default values fix: memory cache checks file permission as well as modification time fix: makefile was including .pyc/.pyo files in tarball fix: spyce.vim syntax highlighting for spyce lambdas fix: error module should be loaded last to avoid stdout module being unloaded on error, thereby causing print statements to no longer go to the browser during error handling fix: error module setHandler used incorrect variable name, causing setHandler to fail updated spyce.vim syntax file for JSP/ASP like delimeters spyce.vim now included in vim distribution rpm generates spyceParserTable.py (allowing for different versions of python) added 'no-store' and 'must-revalidate' to response.uncacheable() added pageerror configuration option to modify default page-level handler rpm now requires http >2.0 and python >2.2 installed For prior release information, refer to the CHANGES file.

Announcing PyQwt-3.7
by Gerard Vermeulen 07 Jul '03

07 Jul '03

PyQwt-3.7 = FAST and EASY data plotting for Python and Qt. PyQwt is a set of Python bindings for the Qwt C++ class library. Qwt extends the Qt framework with widgets for scientific and engineering applications. PyQwt really shines with Numeric and/or numarray. Numeric and numarray extend Python with new data types that make Python an ideal language for numerical computing and experimentation. PyQwt requires and extends PyQt, a set of Python bindings for Qt. PyQwt runs on Windows and Unix/Linux. The home page of PyQwt has moved to http://pyqwt.sourceforge.net. New features in PyQwt-3.7: 1. PyQwt will work with either Numeric, or numarray or both (depending on the presence of Numeric and numarray during PyQwt's build). 2. PyQwt will work without Numeric and numarray (is not recommended). 3. PyQwt is compatible with the Python Command Line Interpreter or IPython, provided that the readline module is installed: Qt's event processing is scheduled by the readline library through (int)(*PyOS_InputHook)(void). 4. PyQwt is always rlcompleter-friendly, even though PyQt-3.6 and earlier are not (the dir() function has been enhanced in PyQt-3.7). 5. The module qwt.qplt is enhanced: qwt.qplt is sugar coating for the QwtPlot widget to facilitate plotting from an interpreter. 6. QwtImagePlot maps a 2-dimensional array of z-values on a QImage using a color scale. 7. New Qwt widgets: QwtDial and QwtCompass. 8. Works with PyQt-3.7, PyQt-3.6, PyQt-3.5 and PyQt-3.4. 9. Works with Qt-2.3.x, Qt-3.0.x and Qt-3.1.x. Gerard Vermeulen

ANN: PyObjC 1.0b1
by Ronald Oussoren 07 Jul '03

07 Jul '03

PyObjC 1.0b1 is now available for download at http://pyobjc.sourceforge.net/ PyObjC is a bridge between Python and Objective-C. It allows full featured Cocoa applications to be written in pure Python. It is also easy to use other frameworks containing Objective-C class libraries from Python and to mix in Objective-C, C and C++ source. Python is a highly dynamic programming language with a shallow learning curve. It combines remarkable power with very clear syntax. The installer package includes a number of Project Builder templates for easily creating new Cocoa-Python projects, as well as support for syntax-coloring Python files in Project Builder. PyObjC also supports full introspection of Objective-C classes and direct invocation of Objective-C APIs from the interactive interpreter. PyObjC requires MacOS X 10.2 or later. PyObjC works both with the Apple provided Python installation in MacOS X 10.2 (and later) and with MacPython 2.3b1. Users of MacPython 2.3b1 can install PyObjC though the PackageManager application. PyObjC 1.0b1 includes numerous improvements over earlier versions, including: * Improved performance and stability * Better tutorials and examples * Initial support for MacOS X 10.1 * Support for the WebKit framework * Write plugin bundles in Python (requires Python 2.3b1) PyObjC is released with an open source license.

ANN: ADEPT (A Declarative, Eval()-based Program Tester)
by phil＠etsu.edu 07 Jul '03

07 Jul '03

ADEPT--"A Declarative, Eval-based Program Tester"--is an open source unit testing tool that allows users to define test cases as tuples-- e.g., # reworking of unittest example from Python unittest doc, # minus initializers and finalizers getTest =\ ( "check default size", eqValue((50,50)), Widget("The Widget").size ) testWidget = Widget("The widget") setTest =\ ( "check resize", eqValue((100,150)), "testWidget.size()", testWidget.resize, (100,150) ) testSuite =\ (("get actions", (getTest,)), ("set actions", (setTest,))) --and then execute, label, log, and check the tests' results: # widgetLogger labels tests, and stores labels and test results # >>> suite =\ [("get actions",(getTest,)), ("set actions",(setTest,))] >>> widgetLogger = TestLogger() >>> doTestSuite(suite, widgetLogger) # # assumption here: all tests succeeded, hence, no advisories # >>> widgetLogger.failureCount() 0 >>> widgetLogger.successCount() 2 >>> widgetLogger.failures() () # # cases could be stored to a list and sorted, if required # >>> widgetLogger.successes() ((2, 1), (1, 1)) >>> map(widgetLogger.getBanner, widgetLogger.successes) ('2.1. set actions: check Widget.resize(100,150)', '1.1. get actions: check Widget default size') The getTest and setTest tuples shown here typify what ADEPT calls "get actions" and "set actions" tests: checks for a callable object's returned results and effects, respectively. *. The getTest tuple, when evaluated as a "get actions" test, directs ADEPT to evaluate eqValue((50,50))(Widget("The widget").size()), and record success iff this expression evaluates to 1 (true). *. The setTest tuple, when evaluated as a "set actions" test, directs ADEPT to execute testWidget.resize(100,150), then record success iff the expression eqValue((100,150))(testWidget.size()) evaluates to 1. I wrote ADEPT as a tool for creating succinct, self-documenting test cases for a large utility that I've been working on since March--3,000+ test cases, with about 3/4 of the way to go. I'm releasing ADEPT because I've appreciated having it, and would like to get people's impressions of ADEPT--along with suggestions for improvement. ADEPT is at http://csciwww.etsu.edu/phil/samples/adept.zip. This first release includes the following: -. a 5 pp. HTML overview of ADEPT's functionality, features, and limitations (http://csciwww.etsu.edu/phil/samples/adept.htm). -. adept.py, ADEPT's source code: about 950 lines of Python, with about 1,000 lines of banners, comments and whitespace (http://csciwww.etsu.edu/phil/samples/adept.py). -. adept.txt, the ADEPT user manual: about 40 pp. of text (60 lines x 80 columns), organized as -. an introduction, plus sections that describe -. ADEPT's nine types of tests: get actions, set actions, get+set actions, null actions, error actions, get prop actions, set prop actions, get prop error actions, set prop error actions --with comments on strategies for using each kind of test, and a special section on repr string testing. -. ADEPT test indexing. -. additional ADEPT features, including nested test suite execution and the use of AND/OR-tree-like objects to apply multiple predicates to a single test. -. ADEPT's design--including notes on how to add test types, and comments on the tool's limitations. (http://csciwww.etsu.edu/phil/samples/adept.txt). -. adeptExamples.py, a program that illustrates the operation of the examples in the ADEPT manual. (http://csciwww.etsu.edu/phil/samples/adeptExamples.py). -. adeptTestSuite.py, a 782-test-case-long validation suite for ADEPT, written in ADEPT. (http://csciwww.etsu.edu/phil/samples/adeptTestSuite.py). =================== Phil Pfeiffer/East TN State U. |Kindness in thought leads to wisdom. Dept. of CIS /P.O.

SpamBayes-1.0a4 Released
by Meyer, Tony 07 Jul '03

07 Jul '03

Hot on the heels of the 1.0a3 release comes Spambayes 1.0a4. This release fixes a couple of potentially serious bugs that were introduced in a3, as well as including various other improvements. Upgrading is recommended for all users. SpamBayes ========= The SpamBayes project (http://spambayes.org) is working on developing a Bayesian anti-spam filter, initially based on the work of Paul Graham. The major difference between this and other, similar projects is the emphasis on testing newer approaches to scoring messages. While most anti-spam projects are still working with the original graham algorithm, we found that a number of alternate methods yielded a more useful response. SpamBayes is implemented purely in Python. New in Alpha Release 4 ====================== Outlook Plug-in --------------- o Display a message for "Delete as Spam" or "Recover from Spam" when SpamBayes is not enabled. o The toolbar is now initialized when "Outlook Today" is the default view. POP3 Proxy ---------- o Fix a bug where long attachments would be broken. o If an exception occurs parsing a message, recover and append a new 'exception' header. (This will be added to other SpamBayes applications by the next release). o Stop including the trailing dot in messages. IMAP Filter ----------- o In imapfilter, try to append without flags if appending fails. o Fix the -i switch in imapfilter and an import error. o Don't try and get password from options if -p is specified in imapfilter. Developer --------- o Various changes/improvements to storage.py. Note that this includes a fix for a potentially serious bug introduced in a3 which could result in incorrect token counts. General ------- o The web interface (used by pop3proxy and imapfilter) now shows the correct date and time in the footer. o A new stripper to squash yet another way of hiding content in HTML spam, like Erections to hide Erections. Transition ========== Transition between release a3 and a4 should be seamless. Refer to the a3 release for information about transitioning between a2 and a4. Reported Bugs Fixed =================== The following bugs tracked via the Sourceforge system were fixed: 761677, 761670 A url containing the details of these bugs can be made by appending the bug number to this url: http://sourceforge.net/tracker/index.php?func=detail&group_id=61702&atid =498103&aid= Feature Requests Added ====================== The following feature request tracked via the Sourceforge system was added: 755098 A url containing the details of these feature requests can be made by appending the request number to this url: http://sourceforge.net/tracker/index.php?func=detail&group_id=61702&atid =498104&aid=
