Arch Linux/Arch Haskell Group Maintainership
The Arch Haskell group maintains AUR packages for Haskell. The Arch Haskell packages make up around 10% of total AUR packages (~2000 packages).
To make the task of implementing the Arch Haskell policy of tracking AUR feasible, we take two approaches:
- massive automation of Hackage to AUR regular conversion, via cabal2arch
- group participation in updating packages.
The first step ensures a consistent user experience:
- cabal2arch should be used to generate all Haskell AUR packages,
- which ensures all naming conventions and other policies are followed,
The second point ensures the Arch Haskell project isn't vulernable to "bus errors" where a user burns out.
The job of an Arch Haskell group maintainer
The concern of an Arch Haskell maintainer is as follows.
- Ensure AUR tracks Hackage versions of packages.
To do this, the following work is done:
- Watch the Hackage RSS feed
- When new packages appear, attempt to build and upload them, with the "build" script (below).
The "build" script
The "build" script is a shell program that wraps cabal2arch. You should always have the latest version of cabal2arch installed. The set of tools you need to run this script are:
- The haskell-archlinux package.
- cabal2arch
- aurploader
- feed-cli
#!/bin/sh
cd /tmp/ set -e
project=`cabal2arch $* 2>&1 | tail -1 | sed 's/Created *//' | xargs basename | sed 's/\..*$//'` echo $project cd $project build || exit 1 cd .. echo "Uploading $project.tar.gz" aurploader -k $project.tar.gz
# create meta files: update the package list and build success list tail -1 ~/.cabal2arch.log | update-aur-log
cp /home/dons/aur.xml /tmp/ url=`/home/dons/bin/get-arch-url $project || cat /tmp/link` echo $url feed-cli new-item -t`cat /tmp/title` --description-file=/tmp/desc -u/tmp/aur.xml -l"$url" rm /tmp/link rm /tmp/title rm /tmp/desc echo scp /tmp/aur.xml code.haskell.org:/srv/code/arch/ cp /tmp/aur.xml $HOME
And additional script does the work of building the package:
set -e
pkg=`sed -n '/pkgname/{s/pkgname=//;p;q}' PKGBUILD`
if makepkg -f ; then echo "$pkg True" >> $HOME/.build-all.log else exit 1 fi
Package Quality Assurance
One script generates this table from build success logs:
Package Publication and Notification
Another updates the RSS feed, so that packages are publicized:
Mapping to Hackage
Yet another updates the distro mapping, so that AUR links are displayed on Hackage
