Add option "--pacnew" to include unmodified .pacnew BACKUP files in package archive when available (instead of locally modified version). Add warning when modified BACKUP files are included. Fix bug in fakeroot invocation. During argument parsing, option flags are shifted off of the argument array. This shifted array was previously passed to fakeroot resulting in the omission of options such as "--nocolor". Avoid this by passing an unshifted copy of the argument array. Replace unnecessary "cat ... |" with "< ..." Update "version" function to match copyright data at top of file. --- contrib/bacman.sh.in | 85 ++++++++++++++++++++++++++++++++++++++-------------- 1 file changed, 63 insertions(+), 22 deletions(-) diff --git a/contrib/bacman.sh.in b/contrib/bacman.sh.in index 5435e40..bcc0e73 100644 --- a/contrib/bacman.sh.in +++ b/contrib/bacman.sh.in @@ -27,6 +27,9 @@ shopt -s nullglob declare -r myname='bacman' declare -r myver='@PACKAGE_VERSION@' USE_COLOR='y' +INCLUDE_PACNEW='n' +# Required for fakeroot because options are shifted off the array. +ARGS=("$@") m4_include(../scripts/library/output_format.sh) @@ -35,19 +38,27 @@ m4_include(../scripts/library/output_format.sh) # usage() { echo "This program recreates a package using pacman's db and system files" - echo "Usage: $myname [--nocolor] <installed package name>" + echo "Usage: $myname [--nocolor] [--pacnew] <installed package name>" echo "Example: $myname kernel26" } version() { printf "%s %s\n" "$myname" "$myver" echo 'Copyright (C) 2008 locci <carlocci_at_gmail_dot_com>' + echo 'Copyright (C) 2008-2013 Pacman Development Team <pacman-dev@archlinux.org>' } -if [[ $1 == "--nocolor" ]]; then - USE_COLOR='n' - shift -fi +while [[ ! -z $1 ]]; do + if [[ $1 == "--nocolor" ]]; then + USE_COLOR='n' + shift + elif [[ $1 == "--pacnew" ]]; then + INCLUDE_PACNEW='y' + shift + else + break + fi +done m4_include(../scripts/library/term_colors.sh) @@ -71,7 +82,7 @@ if (( EUID )); then if [[ -f /usr/bin/fakeroot ]]; then msg "Entering fakeroot environment" export INFAKEROOT="1" - /usr/bin/fakeroot -u -- "$0" "$@" + /usr/bin/fakeroot -u -- "$0" "${ARGS[@]}" exit $? else warning "installing fakeroot or running $myname as root is required to" @@ -140,7 +151,6 @@ cd "$work_dir" || exit 1 # msg2 "Copying package files..." -cat "$pkg_dir"/files | while read i; do if [[ -z $i ]]; then continue @@ -153,24 +163,55 @@ while read i; do case "$current" in %FILES%) - ret=0 - if [[ -e /$i ]]; then - bsdtar -cnf - "/$i" 2> /dev/null | bsdtar -xpf - - - # Workaround to bsdtar not reporting a missing file as an error - if !
