Suggestion of dh_purepython

[Bastian Kleineidam]

Hi Python folks,

I have put together a dh_purepython debhelper script to help
the installation of pure Python packages.

Still missing:

1) All Python X.Y versions need to be preinstalled. What happens
   when you install an new Python version? Hmm, we have to 
   register those pure python packages somehow and byte-compile
   them if we install a new pythonX.Y package.
   
2) in prerm, cope with empty directories being left in
   /usr/lib/pythonX.Y/site-packages

3) sanity check for rm -rf in prerm

4) fix permissions of generated .py[co] files and directories, do not 
   rely on umask

5) see BUGS of dh_purepython, for the compileall.py patch see
http://sourceforge.net/tracker/index.php?func=detailaid=501713group_id=5470atid=305470
 


All needed scripts as well as an example debian package can be
found at http://www.debian.org/~calvin/purepython/.

To install, copy dh_purepython into /usr/bin/ and copy
{postinst,prerm}-purepython to /usr/share/debhelper/autoscripts/.

ATTENTION: to install the example, you need to patch all your 
/usr/lib/pythonX.Y/compileall.py files:
(patch is for 1.5.2, but easy adoptable)

math.exp bug on alpha?

[Luigi Ballabio]

Greetings,
on alpha debian, python 2.1.1-8:
 import math
 math.exp(-720)
aborts the interpreter with a floating point exception. The strange thing 
is, exp(-700) and exp(-750) both work.

Any insight?
Thanks in advance,
Luigi

read all python* binaries from /usr/bin, loop through every one that has a
version on the end, strip the version out and use it.

for i in /usr/bin/python*
do
# if $i ends in a number
# pyver = $i's version number
# call /usr/lib/python$pyver/compileall.py
done

Works for me, no aborts. (i386, python 2.1.1-8)

Just compare the platform... :)

Pyvorbis and ogg comments

[Aquarius]

Does anyone know how to set comments in ogg files using the libvorbis
bindings? I can set a comment non-permanently (the VorbisComment object
works like a dictionary), but I can't work out how to actually *save*
those comments that I've set...

I asked Chris Cheney, the maintainer, and he didn't know; upstream seem
to not be answering mails, so I'm a bit baffled.
