Arch Linux Pacman hooks

Pacman hooks

Some useful Arch Linux Pacman hooks.

Hooks

check-broken-packages

This checks for packages with broken (non satisfied) dynamic library dependencies. This can happen if you have installled package A from the AUR, which depends on B from the official repositories, and B gets updated, but the packager of A does not bump its pkgrel. In most case you simply need to rebuild A.

This is roughly equivalent to the following Bash code:

IFS='
'
for aur_package in $(pacman -Qmm | cut -d ' ' -f 1); do
  for package_file in $(pacman -Ql ${aur_package} | cut -d ' ' -f 2); do
    if [ -f ${package_file} -a -x ${package_file} ]; then
      ldd_output=$(ldd ${package_file} 2> /dev/null)
      if [ $? -eq 0 ]; then
        for line in $(echo ${ldd_output} | grep -F '=> not found'); do
          echo "Missing depency for file ${package_file} from package ${aur_package}: ${line}"
        done
      fi
    fi
  done
done

However it is written in Rust and uses a thread pool for much faster processing (runs in ~1.3s on my machine with ~90 AUR packages, compared to ~14s for the above Bash code).

The hook also detects:

• broken Python packages that were build for an older Python major version
• broken Systemd links for enabled services in /etc/systemd/{user,system}/*.target.*.

pacdiff

Automatically run pacdiff after an upgrade to review pacnew files.

reflector

Selects fastest package mirror, when the pacman-mirrorlist package is upgraded. See https://wiki.archlinux.org/index.php/Reflector#Pacman_hook

sync

Syncs / and /boot partitions when packages are installed, upgraded or removed.

xmonad-recompile

Automatically run xmonad --recompile for each user in the system after xmonad or any of its dependencies is updated.

Installation

Install via the AUR packages:

• check-broken-packages-pacman-hook-git
• pacdiff-pacman-hook-git
• reflector-pacman-hook-git
• sync-pacman-hook-git
• xmonad-recompile-pacman-hook-git

This was previously contained in a single package pacman-hooks-desbma-git, however this is against the AUR guidelines so each hook is now available in a separate package.
