BayPIGgies: Silicon Valley-San Francisco Bay Area Python Users Group When: March 12, 2002 @ 7:30pm Where: Stanford University, Palo Alto, CA Agenda: PyChecker and Friends Speaker: Phil Lindsay "PyChecker and friends: Easing the transition from ad hoc scripts to stable, maintainable Python applications" PyChecker can be thought of as "Lint" for Python, and is a tool for finding bugs in Python source code. This talk will introduce PyChecker, show some of its functionality and discuss some of the lessons learned from its use in a commercial software development environment. The presentation will be from the perspective of a happy user & interested hacker. Some of the future goals of the project's authors will also be described. If time permits, the speaker will demonstrate a couple of small tools he has developed to also help in the creation of stable, maintainable applications. # Call For Talks: We are actively seeking speakers for BayPIGgies! If you would like to give a talk at one of our 2003 meetings (any Python related topic), contact us to coordinate! more info including directions: http://www.baypiggies.net hope 2 c u tomorrow nite! -wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall PTR, � 2001 http://starship.python.net/crew/wesc/cpp/ Silicon Valley-San Francisco Bay Area Python Users Group (BayPIGgies) http://baypiggies.net wesley.j.chun :: wesc at deirdre.org or wesc at fuzzyorange.com cyberweb.consulting : henderson, nv : cyberweb at rocketmail.com http://www.roadkill.com/~wesc/cyberweb/

PSF obtains favorable advance ruling from IRS
by Guido van Rossum 11 Mar '03

11 Mar '03

I'm very pleased to announce that the Python Software Foundation has been recognized by the IRS (the US office of taxation) as a tax-exempt non-profit foundation (aka 501(c)(3)), and that the IRS has given the PSF a "favorable advance ruling" on the PSF's application for recognition as a public charity. Read the IRS ruling here: http://www.python.org/psf/records/tax-exempt.txt Recognition as a public charity has many benefits for the PSF and our community, including strong requirements for public disclosure and accountability, strong legal protections, and freedom from Federal taxation on foundation revenue. Contributions to the PSF are also tax-deductible for purposes of US income tax, subject to the same regulations as donations to any public charity. The PSF hasn't solicited contributions so far, waiting for the IRS ruling. Now that we have a favorable advance ruling, as the letter states we need to demonstrate broad public financial support to retain public charity status. A PSF committee is looking into ways to make contributing as easy as possible (like "click here to donate"). If you can't wait, the best way to contribute now is via check: http://www.python.org/psf/donations.html The PSF currently has financial responsibility for PyCon DC 2003: http://www.python.org/pycon/ Provided that doesn't bankrupt us :-), other things the PSF does (and would like to do) are given in the PSF's mission statement: http://www.python.org/psf/mission.html So get those donations coming! (Non-US residents are encouraged to donate, and their donations will be counted as public financial support, but such donations are generally not tax-exempt for the donor. To change this would require setting up PSF subsidiaries in many countries; we don't have the resources to do this. Check your local tax law; there may be exceptions.) --Guido van Rossum (home page: http://www.python.org/~guido/)

cx_Oracle 3.0
by Anthony Tuininga 10 Mar '03

10 Mar '03

What is cx_Oracle? cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a few exceptions. Where do I get it? http://computronix.com/utilities What's new? 1) Removed support for connection to Oracle7 databases; it is entirely possible that it will still work but I no longer have any way of testing and Oracle has dropped any meaningful support for Oracle7 anyway 2) Fetching of strings is now done with predefined memory areas rather than dynamic memory areas; dynamic fetching of strings was causing problems with Oracle 9i in some instances and databases using a different character set other than US ASCII 3) Fixed bug where segfault would occur if the '/' character preceded the '@' character in a connect string 4) Added two new cursor methods var() and arrayvar() in order to eliminate the need for setinputsizes() when defining PL/SQL arrays and as a generic method of acquiring bind variables directly when needed 5) Fixed support for binding cursors and added support for fetching cursors (these are known as ref cursors in PL/SQL) 6) Eliminated discrepancy between the array size used internally and the array size specified by the interface user; this was done earlier to avoid bus errors on 64-bit platforms but another way has been found to get around that issue and a number of people were getting confused because of the discrepancy 7) Added support for the attribute "connection" on cursors, an optional DB API extension 8) Added support for passing a dictionary as the second parameter for the cursor.execute() method in order to comply with the DB API more closely; the method of passing parameters with keyword arguments is still supported and is in fact preferred 9) Added support for the attribute "statement" on cursors which is a reference to the last SQL statement prepared or executed 10) Added support for passing any sequence to callproc() rather than just lists as before 11) Fixed bug where segfault would occur if the array size was changed after the cursor was executed but before it was fetched 12) Ignore array size when performing executemany() and use the length of the list of arguments instead 13) Rollback when connection is closed or destroyed to follow DB API rather than use the Oracle default (which is commit) 14) Added check for array size too large causing an integer overflow 15) Added support for iterators for Python 2.2 and above 16) Added test suite based on PyUnitTest 17) Added documentation in HTML format similar to the documentation for the core Python library -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software.
