Recursive constructors?
by roy＠popmail.med.nyu.edu July 30, 1999

July 30, 1999

Is it legal for a constructor function to call itself recursively? I.e.: class foo: def __init__(self, x): if (whatever): self.bar = foo(y) -- Roy Smith <roy(a)popmail.med.nyu.edu> New York University School of Medicine

Is "shelve" thread-safe on Windows?
by Andrew Dolan July 30, 1999

July 30, 1999

Hi All, I hope to use the shelve module to store data which may be accessed from several Python CGI scripts at once. I have studied the source-code and it seems that the anydbm code (that shelve relies on) falls-back to using the dumbdbm module on Windows which is not safe for concurrent access (according to comments in its source code). Can anyone suggest a simple way to gain the functionality of "shelve" on a Windows platform, but which is safe for handling concurrent accesses (like from CGI scripts)? Cheers, Ian. -- Any views expressed in this email are my own and not those of Logica UK.

Python/PostgreSQL interface module
by jonathan＠onegoodidea.com July 30, 1999

July 30, 1999

well after much lurking and occasional commenting on these groups, here is my first contribution to the community. it's a module for accessing PostgreSQL databases from Python. yes, i know there already is one, but i wanted to play with some different features and to get the hang of writing extension modules. you are free to not use this module. please don't email me to tell me i've wasted my time - all learning is worthwhile and maybe someone else will get something useful from this. i'm afraid it doesn't have a proper name yet because i can't think of one - a free copy of the source for the best idea ;-) i welcome feedback, :-j (extracted from the README:) Python/PostgreSQL Interface Module (Version: 1.0) ---------------------------------- Summary: -------- PostgreSQL is a neat, free, relational database system which can be found at: <http://www.postgresql.org/> This is a module that provides the PostgreSQL programmers' API to Python programmers. It is written in C and compiles down to a shared-object file that can be dynamically loaded into the Python interpreter. It is basically a wrapper around the 'libpq' library that comes with PostgreSQL. Limitations: ------------ This interface has not been used in anger yet. It's been written as part of a one good idea project and I'm releasing it more widely because it may be of use to other people and might result in some useful feedback. License: -------- There should be a LICENSE file accompanying this distribution (and at the top of each source file). I've used the Berkeley license because I've always liked it. This code is not copylefted, feel free to stick it into a commercial product and sell it, become rich, buy a small island in the pacific, retire young and happy. However, you have to retain the copyright on the code, and it would be polite to send me a note of thanks ;-) Obtaining The Latest Distribution: ---------------------------------- You should be able to find it by following the obvious links on the one good idea webpages for 'Projects': <http://www.onegoodidea.com/> As of this distribution, the appropriate URL was: <http://www.onegoodidea.com/downloads/python-postgresql-1.0.tgz> PyGreSQL -------- This module is not PyGreSQL. PyGreSQL is written by D'Arcy J.M. Cain, <darcy(a)druid.net>. It is another Python/PostgreSQL interface which has been around longer than this one. I wrote this module because I wanted a different mechanism for accessing named fields in query results (and partly as an exercise in extending Python). == jonathan hogg, one good idea limited, 25 clouston street, glasgow g20 8qr, uk jonathan(a)onegoodidea.com www.onegoodidea.com t:(0)976-614338 f:(0)7970-537451 <P><A HREF="http://www.onegoodidea.com/projects.html">Python/PostgreSQL API</A> - access PostgreSQL programmers' API from Python.

RTSP streaming media proxy
by jonathan＠onegoodidea.com July 30, 1999

July 30, 1999

hot on the heels of my last post, here is my next contribution. again, it can be found on the projects page of our company web-site: <http://www.onegoodidea.com/projectscore.html> RTSP_Proxy is a proxy server for the RTSP/RTP streaming media protocols. this is a quick-and-dirty hack i threw together a couple of weekends ago in order to be able to watch the MacWorld keynote address which was netcast using QuickTime 4 video/audio streaming. for information on QuickTime 4, take a look at: <http://www.apple.com/quicktime/> unfortunately, whilst apple chose a non-proprietry standard protocol for implementing their streaming architecture, they also chose one which is not particularly established and is not IP masquerading friendly. apple provide a proxy server for running on a firewall/NAT machine, but it's pretty flaky so i had a stab at writing my own. i've only run it on an i386 linux box, but i've been told it works on freebsd too. it requires threads and sockets, but should work on anything that provides them. it's not a pretty program, but it worked enough for me to watch the new iBook being launched :-) i'm in the process of writing a new version, but thought this might be of interest/amusement. again, all comments welcome, :-j == jonathan hogg, one good idea limited, 25 clouston street, glasgow g20 8qr, uk jonathan(a)onegoodidea.com www.onegoodidea.com t:(0)976-614338 f:(0)7970-537451 <P><A HREF="http://www.onegoodidea.com/projectscore.html">RTSP proxy</A> - quick-and-dirty proxy server for the RTSP/RTP streaming media protocols, written in Python.

NT select.select?
by Markus Stenberg July 30, 1999

July 30, 1999

Is there some low limit on maximum number of sockets you can have in the Python-NT's select call? A program that happens to work perfectly on Linux seems to die on NT around 64(?) sockets to the 'too many file descriptors in call' error. Any portable ways to bypass it? -Markus -- "He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." - Friedrich Nietzsche, _Beyond Good and Evil_

How to set text color using pyKDE 0.8?
by Peter Torstenson July 30, 1999

July 30, 1999

I'm using pyKDE 0.8 binding for python. I made a QLabel on the main widget. Now I'd like to change the color of the text inside this QLabel. I managed to change the backgroundcolor and the font. But I can't find any info on how to change the color of the text, or the foregroundcolor. /Peter Torstenson Rio de Janeiro
