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 checksum for updated PKGBUILD to check if it matches manually generated checksum.
• if it matches an automatic update is started (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 wants to upgrade the remaining packages

yay-generate-PKGBUILD-checksum

find here

sublements yay-all, used to manually generate checksums for AUR PKGBUILDs

Why?

PKGBUILDS contain checksum and pkg versions sections. These alter the checksum generated for a PKGBUILD anytime there is an update. The point of this function/script is to not see checksum changes unless instructions in a given PKGBUILD change.
