iconv codec
by M.-A. Lemburg March 31, 2003

March 31, 2003

Since the introduction of the iconv codec there have been numerous bug reports related to the codec and the lack of cross platform support for it (ranging from: the codec doesn't compile and the codec doesn't support standard names for common encodings to core dumps in the linking phase). I'd like to question whether the codec is really ready for prime time yet. Right now it causes people more trouble than it does any good. Some examples: https://sourceforge.net/tracker/?group_id=5470&… [View More]

Compiler treats None both as a constant and variable
by Raymond Hettinger March 30, 2003

March 30, 2003

>>> def f(): None >>> dis(f) 2 0 LOAD_GLOBAL 0 (None) 3 POP_TOP 4 LOAD_CONST 0 (None) 7 RETURN_VALUE >>> None = 1 <stdin>:1: SyntaxWarning: assignment to None >>> f() == None False Is this a bug? Should the compiler use the GLOBAL in both places? Or, is it reasonable to use CONST in both places? Raymond Hettinger

ossaudiodev tweak needs testing
by Greg Ward March 25, 2003

March 25, 2003

Hi all -- I have another tweak to the ossaudiodev module that might make it work a little better. Background: some time ago, Jeremy and Guido had problems with test_ossaudiodev hanging due to a blocking open() call. So I made the open() non-blocking in rev 1.25 on 2003/03/11. But that screwed things up for David Hammerton, who emailed me privately the other day that a write() call later on was dying with EAGAIN -- not entirely surprising, since that's how write() is supposed to behave on a … [View More]

funny leak
by Christian Tismer March 24, 2003

March 24, 2003

Hi Tim et al, I just tested generators and found a memory leak. (Has nothing to do with generators). The following code adds one to the overall refcount and gc cannot reclaim it. def conjoin(gs): def gen(): gs # unbreakable cycle gen # unless one is commented out Should I send a bug report, or is this known? The above holds for Python 2.2.2 upto the current CVS version. ciao - chris -- Christian Tismer :^) <mailto:tismer@tismer.com> … [View More]

How to suppress instance __dict__?
by David Abrahams March 24, 2003

March 24, 2003

I am generating extension types derived from a type which is derived from int 'int' by calling the metaclass; in order to prevent instances of the most-derived type from getting an instance __dict__ I am putting an empty tuple in the class __dict__ as '__slots__'. The problem with this hack is that it disables pickling of these babies: "a class that defines __slots__ without defining __getstate__ cannot be pickled" Yes, I can define __getstate__, __setstate__, and __getinitargs__ (the … [View More]
