Re: [gentoo-dev] Prelinking in Gentoo and interactions with portage

[Stefan Jones <cretin@gentoo.org>]

Hi ppl, I have make a draft version of the portage changes needed.

I am not a python programmer, or want to be! The code can be optimised a
bit but I believe that prelink was well programmed so all checks for
file type etc are best handled by C based prelink, as long as os.system
is fast.

I have created code which adds support for the FEATURE flag prelink.
If it exists it uses prelink to verify the md5sums.
Also it prelinks files as they are installed.

Most importantly it works for me! Happy testing!

code:
download from
http://cvs.gentoo.org/~cretin/portage.py
This is based on the latest CVS portage

TODO: 
* Safety checks for existence of /usr/sbin/prelink
* optimise to minimise number of calls to prelink
* see if a less IO intensive md5sum method exists  (of course it does!)

now to sleep .....
