New PostgreSQL Database Adapters: psycopg and ZpsycopgDA
by Federico Di Gregorio 28 Feb '01

28 Feb '01

Hi *, the guys here at initd (http://initd.org/) arre happy to announce the release of psycopg, a Python/PostgreSQL driver module and ZPsycopgDA, a Zope Database Adapter based on the psycopg driver. Now, I'll answer the questions you asked... (_what_ questions? well... follow me...) Q. Why another postgresql dba? we already have pygres and popy! A. That's true. We had some ideas about a performant, thread-safe driver and we wanted to hack a little bit. the resulting driver is slim, fast, with clean code and some nice features (see below.) Writing a Zope DBA was a logical consequence only because we use it. Q. Should I switch to psycopg and zpsycopgda? A. Not if you are happy with your current driver [and i hope it is popy ;-)] The only real reason is if you want the advanced features you can find only in psycopg: 1/ level-2 thread safety 2/ advanced type-casting system 3/ automatic management of multiple phisical connections to the DB (one per thread) to speed up queries 4/ extremely clean and maintainable code also, in a future release (0.5) zpsycopgda will support db and table management from zope management screens. Q. Hey! you're from MIXAD LIVE, is psycopg a popy fork? A. No, psycopg is 100% clean code. we had some ideas on how a db driver should workin a heavily multithreaded environment and we wanted to test them. that's all. Q. Where can I download it? A. http://initd.org/Software/psycopg (tarball and precompiled debian packages) ciao and good hacking, federico -- Federico Di Gregorio MIXAD LIVE Chief of Research & Technology fog(a)mixadlive.com Debian GNU/Linux Developer & Italian Press Contact fog(a)debian.org Qu'est ce que la folie? Juste un sentiment de liberté si fort qu'on en oublie ce qui nous rattache au monde... -- J. de Loctra

Python 1.6.1 released towards GPL incompatibility
by Guido van Rossum 27 Feb '01

27 Feb '01

The Corporation for National Research Initiatives has released Python 1.6.1. This is a "bugfix" release for Python 1.6, fixing a GPL incompatibility in the license. The new 1.6.1 release can be found here: http://www.python.org/1.6.1/ There is great subtlety to GPL compatibility. I refer to the webpages of the Free Software Foundation for an explanation, in particular http://www.gnu.org/philosophy/license-list.html. This change does not imply that Python 2.0 or later versions are now compatible with the GPL. Similar changes to their licenses need to be made there; these are still under negotiation. I'll keep you posted. --Guido van Rossum (home page: http://www.python.org/~guido/)

ANN: Win32 Installer - new release for Python 2
by Gordon McMillan 24 Feb '01

24 Feb '01

With many, many thanks to Barry Scott, a new release of the Win32 Installer package is here: http://www.mcmillan-inc.com/install1.html Barry found my major boo-boo in the code that resolves a C extension inside a package. He also greatly improved the messages that come out of the runtime when something goes wrong at the top level. And if you're a user of Mark Hammond's stuff, he also made it so, for example, "import pywintypes" automatically finds PyWinTypes20.dll. Also in this release: the fix for builtin modules, and a fix to the analysis of C extensions and dlls. The documentation now has a page of how-tos for common extensions / packages (e.g., Pmw, PIL among others). Background: The Win32 Installer is a sort of compilerless Freeze - a way of distributing Python apps with all the required support built in. It also understands binary resources (.dlls and .pyds) and can package up arbitrary files that your app might require. Old-Python-style license. Contact: gmcm(a)hypernet.com <P><A HREF="http://www.mcmillan-inc.com/install1.html"> Win32 Installer release 3j</A> A compiler-less way of distributing Python 2.0 apps on Windows.
