Dear Maintainer, please add a --cache-size-limit option or some such. from #debian-reproducible today: < h01ger> josch: i just committed this crime: bin/debrebuild_cache_limiter.sh * r.d.n: add script to work around/implement a missing feature of debrebuild * https://salsa.debian.org/qa/jenkins.debian.net/-/commit/2db5e98 < h01ger> josch: for the upcoming debrebuild bug report, i'm not sure whether you can rely on atime being a sensible source of information and how to implement host specific limits. i guess with --cache-size, and then its up to the user how to call that < h01ger> for the time being i intend to call bin/debrebuild_cache_limiter.sh manually, as i've been doing the last weeks anyway. (only 2-3 hosts really need it and there's i just ran one long command daily manually. this is a bit better and probably even safe to run in cron or some such...) For easier reference, the script is as follows: $ cat bin/debrebuild_cache_limiter.sh #!/bin/bash # # Copyright 2025 Holger Levsen (hol...@layer-acht.org) # released under the GPLv2 CACHE=~rebuilderd/cache if [ ! -d $CACHE ] ; then echo "$CACHE does not exist." exit 1 fi case $HOSTNAME in ionos17*) LIMIT=50 ;; codethink*) LIMIT=20 ;; osuosl*) LIMIT=333 ;; infom07*) LIMIT=200 ;; # FIXME: drop extra partition again? infom08*) LIMIT=100 ;; riscv64*) LIMIT=180 ;; *) echo "Limit for $HOSTNAME not defined." exit 1 ;; esac # delete 1000 oldest files # FIXME: use atime, but then, this script should not exist in the first place... :) find $CACHE -type f -printf '%T+ %p\n' | sort | head -n 1000|cut -d ' ' -f2-|xargs sudo rm set -e set -o pipefail SIZE=$(du -sh $CACHE | grep G | cut -d 'G' -f 1) if [ $SIZE -gt $LIMIT ] ; then echo "$CACHE is still ${SIZE}G, reducing further." $0 else echo "$CACHE is ${SIZE}G, voila." fi exit 0 & thanks a lot for debrebuild, it's extremely useful and very much works very well! -- cheers, Holger ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ holger@(debian|reproducible-builds|layer-acht).org ⢿⡄⠘⠷⠚⠋⠀ OpenPGP: B8BF54137B09D35CF026FE9D 091AB856069AAA1C ⠈⠳⣄ Another end of the world is possible.
