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.
