I think that this is the last change from Parabola that would be welcome in devtools. It shoves the initial variable setup inside of a `init_variables()` function, and the loose code at the end into a `main()` function, which it calls as the very last line. My motivation for this is that in Parabola, makechrootpkg is used as a library, not as an executable, and so this makes adjusting it to be a library as simple as removing the `main "$@"` line from the end. However, I do think that the change stands on its own for 2 reasons; using a `main()` function is good because - deferring execution until the entire script has been parsed avoids weird things happening if the user upgrades the program while an instance of it is running - generally good for code quality Naturally, this re-indents a a decent size block of code, which means that rebasing or merging with it is a pain. -- Happy hacking, ~ Luke Shumaker

By using declare here, you're scoping the variables to the function.

You are, of course, correct. I'm submitting a revised patch that adds the `-g` flag to `declare`. Also, as I mention in the revised commit message, you may wish to get rid of the init_variables() function, and move that bit into the main() function; which would make the concern go away. -- Happy hacking, ~ Luke Shumaker

From: Luke Shumaker This means wrapping variable initialization in init_variables(), and the main program routine in main(). I did NOT put `shopt -s nullglob` in to a function. It make make sense to move init_variables() down into the main() function, instead of having it as a separate function up top (if this done, then the `-g` flag passed to `declare` in init_variables() can be dropped). However, in interest of keeping the `diff -w` small, and merges/rebases simpler, this isn't done here. --- makechrootpkg.in | 252 ++++++++++++++++++++++++++++--------------------------- 1 file changed, 130 insertions(+), 122 deletions(-) diff --git a/makechrootpkg.in b/makechrootpkg.in index f6764cb..a221f7c 100644 --- a/makechrootpkg.in +++ b/makechrootpkg.in @@ -15,26 +15,28 @@ m4_include(lib/archroot.sh) shopt -s nullglob -default_makepkg_args=(-s --noconfirm -L --holdver) -makepkg_args=("${default_makepkg_args[@]}") -repack=false -update_first=false -clean_first=false -run_namcap=false -temp_chroot=false -chrootdir= -passeddir= -makepkg_user= -declare -a install_pkgs -declare -i ret=0 - -bindmounts_ro=() -bindmounts_rw=() - -copy=$USER -[[ -n ${SUDO_USER:-} ]] && copy=$SUDO_USER -[[ -z "$copy" || $copy = root ]] && copy=copy -src_owner=${SUDO_USER:-$USER} +init_variables() { + default_makepkg_args=(-s --noconfirm -L --holdver) + makepkg_args=("${default_makepkg_args[@]}") + repack=false + update_first=false + clean_first=false + run_namcap=false + temp_chroot=false + chrootdir= + passeddir= + makepkg_user= + declare -ga install_pkgs + declare -gi ret=0 + + bindmounts_ro=() + bindmounts_rw=() + + copy=$USER + [[ -n ${SUDO_USER:-} ]] && copy=$SUDO_USER + [[ -z "$copy" || $copy = root ]] && copy=copy + src_owner=${SUDO_USER:-$USER} +} usage() { echo "Usage: ${0##*/} [options] -r <chrootdir> [--] [makepkg args]" @@ -308,109 +310,115 @@ move_products() { } # }}} -while getopts 'hcur:I:l:nTD:d:U:' arg; do - case "$arg" in - c) clean_first=true ;; - D) bindmounts_ro+=(--bind-ro="$OPTARG") ;; - d) bindmounts_rw+=(--bind="$OPTARG") ;; - u) update_first=true ;; - r) passeddir="$OPTARG" ;; - I) install_pkgs+=("$OPTARG") ;; - l) copy="$OPTARG" ;; - n) run_namcap=true; makepkg_args+=(-i) ;; - T) temp_chroot=true; copy+="-$$" ;; - U) makepkg_user="$OPTARG" ;; - h|*) usage ;; - esac -done - -[[ ! -f PKGBUILD && -z "${install_pkgs[*]}" ]] && die 'This must be run in a directory containing a PKGBUILD.' -[[ -n $makepkg_user && -z $(id -u "$makepkg_user") ]] && die 'Invalid makepkg user.' - -check_root - -# Canonicalize chrootdir, getting rid of trailing / -chrootdir=$(readlink -e "$passeddir") -[[ ! -d $chrootdir ]] && die "No chroot dir defined, or invalid path '%s'" "$passeddir" -[[ ! -d $chrootdir/root ]] && die "Missing chroot dir root directory.
