[gentoo-dev] CONTENTS file

[gentoo-dev] CONTENTS file

[Andrew Gaffney]

I'm writing a Perl script that verifies file MD5SUMs against what portage recorded in 
/var/db/pkg/category/package/CONTENTS at install. I'm wondering what would happen in that 
file if some package were to install a file that had a space in the name. Currently, a 
line looks like:

obj /usr/libexec/webmin/acl/defaultacl a6897506f8609645d3a215988d1a937c 1063945574

This can easily be pulled apart with a regex, but what if it looked like this:

obj /usr/libexec/webmin/acl/default acl a6897506f8609645d3a215988d1a937c 1063945574

Can this happen?

Maybe s/ /\ /g?

yes, and it still can be 'easily' pulled apart ... the type is the first 
param, the mtime is the last param, the md5 is the 2nd to last, and the 
filename is everything in between the type and the md5 ;)

So, something like:

/^(\w+) (.+) (\w+) (\d+)$/

probably.



I'd suggest starting the regexp from the back.  Since the last fields
are always the same, that makes everything before the two last fields
the filename.

i've been doing the same thing some time ago. so maybe you want to take 
a look, improve, throw away or let it inspire you. you can find an 
ebuild for my program here: http://frozenfire/NEMESiS/dl/augur-0.1.ebuild
the url for the perl-script is included

one can be wrong. it's
http://frozenfire.dnsalias.net/NEMESiS/dl/augur-0.1.ebuild

(damn!, sorry luke, next time i'll think of adressing the mail to

Andrew,

I'm catching up on old mail.  See epm for this.  Epm is written in perl
and does exactly the checking you're describing.
