Pacget: Super fast pacman downloads

Question

I spent all day (yes I'm a slow horrible programmer) writing this scrip. It takes the download url from pacman, then looks up the mirror list in /etc/pacman.d/<repo> and adds them all as mirrors to aria2.
What ends up happening is aria2c connects to 10-20 servers downloading from all of them at the same time, which should give anyone on broadband a huge boost in download speed. This boosted my download speeds from 100-300KB/s to 2,000KB/s (my connections limit).

Hope you guys like it.
ps: would making a package out of this be overkill?, like one that auto installs everything?

Answer 1

noriko, I liked your idea with changing the testing repo. I made it so the script now tests if the /etc/pacman.d/repo file exists, if it does it'll just use it, otherwise it'll just do one mirror. So if you have an /etc/pacman.d/testing, it should now use it.
I mad a few revisions that I want to post up on here first to get some feedback on it before I change the wiki.
Whats changed is the repo check, and I made it so:
less then 5mb = 3 mirrors
less then 10mb = 7 mirrors
greater then 10mb = 30 mirrors
Also to clearify:
Any repo database file will only use one mirror (they are usually very small and not worth being split up).
Sorry for the messy script, I'll clean it up soon and add comments/allow easy modifications to it.
/usr/bin/pacget
#!/bin/bash
#pacget script
rm -f *.aria2
cachedir=/var/cache/pacman/pkg
file=$(awk -F '/' '{ print $NF }' <<<$1)
echo Downloading: $file|sed 's,/,,'
#exit 0
repo=$(awk -F '/' '{x=NF-3 } { print $x }' <<<$1)
echo repo: $repo
#exit 0
function numir {
size=$(sed -n '/^%CSIZE%$/{n;p}' /var/lib/pacman/$repo/$(sed 's/.pkg.tar.gz//'<<< $file)/desc)
if [[ $size -lt 5000000 ]]; then
m=3
elif [[ $size -lt 10000000 ]]; then
m=7
else
m=30
fi
if [[ $2 = *.db.tar.gz.part || ! -f /etc/pacman.d/$repo ]]; then
echo "(using one mirror)"
mirrors=$1
else
if [ -f /etc/pacman.d/$repo ]; then
numir
mirrors=$(sed -n 's/^Server = //; s,$,/'"$file"', ; /^ftp/p; /^http/p' /etc/pacman.d/$repo|head -$m)
fi
fi
aria2c -t20 -m2 -l /root/log $mirrors -o $file.pacget
if [ -f $cachedir/$file.pacget.aria2 ]; then
rm $cachedir/$file.pacget $cachedir/$file.pacget.aria2
exit 0
fi
mv $file.pacget $2
exit 0
PS: Tell me if I should post this version up on the wiki.

i used it, works perfectly btw Wink but it's not enhancing anything lol.. my download is still still stuck at 240-5 kb/s ..
hmm.. might me an isp limit of some sorts....
