Arch Linux - yay and pacman

Pacman Throttle Bandwidth

If you are on a slow internet connection and you do not want to break internet access for anyone else on the network (or yourself for that matter) you need to throttle pacman and yay.
This is why I wrap both commands. They are throttled or unthrottled based on the file /tmp/pacman-bandwidth-limit.

• pacman
• yay

This is implemented via trickle.

yay-all

find here

• downloads new official packages (runs pacman -Syu)
• then executes yay -G <pkg-name (updates PKGBUILD)
• generates a checksum for the updated PKGBUILD to check if it matches the manually generated checksum
• if it matches it starts an automated update (root privileges required, single time sudo approval)
• it does this ^ for a list of packages defined in pkgs_with_saved_checksums=()
• afterwards it runs a normal yay upgrade and asks the user if he/she want to upgrade the remaining packages

yay-generate-PKGBUILD-checksum

find here

This supplements yay-all. It generates checksums for AUR PKGBUILDs.

Why?

A PKGBUILD contains a checksum and pkg version section. These alter the checksum generated for a PKGBUILD anytime there is a version update. The point of this function/script is to ignore changes unless instructions in a given PKGBUILD change.
