I wrote a quick python hack to look for any current packages that obsolete any
other current package. I've included it at the end of this email.
Unfortunately, I think it would take just about forever for me to run it
(~5000 urpmf calls). Anyone who can run it faster, I'll be your best friend
and love you forever and ever and all that stuff....
You'll probably have to change line 6 (where I set urpmflags to select the
right media), but that's about it. Oh, and ignore the tmpnam warnings;
there's no other good alternative without python-expect or -pexpect. Just
don't run two copies at once.
Also, I have a few questions:
1. Is there a faster way to do this than running urpmf ~5000 times?
2. Does running urpmf ~5000 times go out to the internet ~5000 times?
3. Would it help if I did this in perl (because we have a perl-URPM but not a
python-URPM)?
4. Would anyone besides me want a python-URPM? (This would obviously take some
time, but I'd be happy to look into it.)
5. Is there actually no python-expect or python-pexpect? Would anyone besides
me want it? (This would take a few minutes.)
6. While I'm at it, does anyone want any other python packages? For my own
use, I've packaged up
python-{rational,cRat,fpconst,indices,xoltar,xzip,Itpl,logging} and would be
happy to share them (or, for that matter, describe them) if there's any
potential interest. I'd be happy to similarly package up any common python
modules....
