[gentoo-user] Portage: Show list of required files without downloading anything?

[gentoo-user] Portage: Show list of required files without downloading anything?

[-- Attachment #1: Type: text/plain, Size: 1139 bytes --]

My mother has a computer which still accesses the internet via a dialup
connection. When I do upgrades on her system, I typically grab a portage
snapshot from my system, drive up to her house 12 miles away, install
it, check to see which packages need upgrading, then somehow figure out
(never exactly) which files she actually needs so I can get them, again,
from my system, drive those files back up to her house and compile stuff
hoping I didn't miss anything too sizable.

Question: Is there a way that I can get Portage to run through the
packages/ebuilds and, instead of downloading anything from the net, just
have it show me which files were not in /usr/portage/distfiles which
will be needed?

So if I had 8 packages which needed upgrading, which would result in (an
estimated) 6,382K of downloads, is there some way for me to have it go
through each one of those all at once, similar to --fetchonly, and have
it spit out a list of everything which it did not find on the local
system?

It seems to be simple enough and a useful feature on some level but I
haven't found the answer.

Thoughts?

Dunno about any script, but first step would be:
	
	emerge -uD -fp world

Then just filter it, e.g. in every line cut everything after the first
white space and throw the meat to wget.

Something like:

# export DISTDIR=$(emerge --info | sed -n 's/^DISTDIR="\(.*\)"$/\1/p')
# emerge --fetchonly --pretend --quiet -u world | \
        grep -v "^$" | \
        while read SRC_URI; do \
                filename=`basename "${SRC_URI}"`; \
                [ ! -f "${DISTDIR}/${filename}" ] && \
                        echo "${SRC_URI}"; \
        done

You might also consider creating a binhost on your network and bringing binary 
packages instead of sources to her computer...

Hi,

I would do something like this :

- "emerge aria2" on your box (nice wget replacement which can download
from more hosts/protocols at the same time).

- run this command on your mother's box :

for url in $(emerge -fpuvDN world|grep -v "These are the packages that
would be fetched, in order:"|grep -v "Calculating") ; do echo ; echo
aria2c $url ;done > packages.sh

- copy the packages.sh on your box

-  run  ". packages.sh" on your box. This will download all the
required pakages in the current directory.

regards,

Boris.

DISTDIR=$(portageq distdir)

looks less like line noise and it harder to mis-type :)

I do not like this dumb machine
I really ought to sell it.
It never does just what I want
But only what I tell it.
