From 38d47c48d657ac09f1809f6c85b2ef09b5531fb7 Mon Sep 17 00:00:00 2001 From: Luke Shumaker Date: Wed, 15 Feb 2017 14:40:06 -0500 Subject: makechrootpkg, arch-nspawn: Force-enable local '/repo/' repository. The change in arch-nspawn is subtle: This was the source of "infamous" "it fails every other time" bug that took me over a year to solve. By having a repository of local packages (rather than simply running `pacman -U`), we are inviting pacman to cache them in `/var/cache/pacman/pkg`. Besides being needless disk writes, this actually causes a real issue. If the package gets rebuilt, pacman will balk, as the file no longer matches the cached signature. So, how do we prevent pacman from caching these local packages? Simple: include the directory they are already in in the pacman.conf:CacheDir list. This will prevent pacman from copying the files to one of the other cache directories. --- arch-nspawn.in | 1 + makechrootpkg.in | 12 ++++++++++++ 2 files changed, 13 insertions(+) diff --git a/arch-nspawn.in b/arch-nspawn.in index 30100f7..adee72e 100644 --- a/arch-nspawn.in +++ b/arch-nspawn.in @@ -106,6 +106,7 @@ elif [[ $(cat "$working_dir/.arch-chroot") != $CHROOT_VERSION ]]; then fi build_mount_args +cache_dirs+=('/repo/') copy_hostconf eval $(grep '^CARCH=' "$working_dir/etc/makepkg.conf") diff --git a/makechrootpkg.in b/makechrootpkg.in index 416d598..52c2c10 100644 --- a/makechrootpkg.in +++ b/makechrootpkg.in @@ -309,6 +309,18 @@ builduser ALL = NOPASSWD: /usr/bin/pacman EOF chmod 440 "$copydir/etc/sudoers.d/builduser-pacman" + if ! grep -q '^\[repo\]' "$copydir/etc/pacman.conf"; then + local line=$(grep -n '^\[' "$copydir/etc/pacman.conf" |grep -Fv ':[options]'|sed 's/:.*//;1q') + local ins='[repo] +SigLevel = Optional TrustAll +Server = file:///repo +' + sed -i "${line}i${ins//$'\n'/\\n}" "$copydir/etc/pacman.conf" + fi + # Avoid having to use `pacman -Sy` to update [repo], as + # networking might be disabled inside of the chroot. + cp "$copydir/repo/repo.db" "$copydir/var/lib/pacman/sync/repo.db" + # This is a little gross, but this way the script is recreated every time in the # working copy { -- cgit v1.2.3-70-g09d2
