Use the correct database format Use xdelta3 to get the source and destination files from the delta itself
Allow delta files to be added with repo-add just like package files. delta files can also be removed with repo-remove. This is simply done by looking for a .delta extension in the arguments, and calling the appropriate db_write_delta or db_remove_delta functions. Example usage: repo-add repo/test.db.tar.gz repo/libx11-1.1.99.2-2-x86_64.pkg.tar.gz repo-add repo/test.db.tar.gz repo/libx11-1.1.5-2_to_1.1.99.2-2-x86_64.delta repo-remove repo/test.db.tar.gz libx11-1.1.5-2_to_1.1.99.2-2-x86_64.delta Signed-off-by: Xavier Chantry <[email protected]> --- scripts/repo-add.sh.in | 102 +++++++++++++++++++++++++++++++++++++++++++++-- 1 files changed, 97 insertions(+), 5 deletions(-) diff --git a/scripts/repo-add.sh.in b/scripts/repo-add.sh.in index 9cf66e5..504adfd 100644 --- a/scripts/repo-add.sh.in +++ b/scripts/repo-add.sh.in @@ -57,8 +57,8 @@ error() { # print usage instructions usage() { printf "repo-add, repo-remove (pacman) %s\n\n" "$myver" - printf "$(gettext "Usage: repo-add [-q] <path-to-db> <package> ...\n")" - printf "$(gettext "Usage: repo-remove [-q] <path-to-db> <packagename> ...\n\n")" + printf "$(gettext "Usage: repo-add [-q] <path-to-db> <package|delta> ...\n")" + printf "$(gettext "Usage: repo-remove [-q] <path-to-db> <packagename|delta> ...\n\n")" printf "$(gettext "\ repo-add will update a package database by reading a package file.\n\ Multiple packages to add can be specified on the command line.\n\n")" @@ -107,6 +107,73 @@ find_pkgentry() return 1 } +# Get the package name from the delta filename +get_delta_pkgname() { + local tmp + + tmp=${1##*/} + echo ${tmp%-*-*_to*} +} + +# write a delta entry +# arg1 - path to delta file +db_write_delta() +{ + deltafile="$1" + pkgname="$(get_delta_pkgname $deltafile)" + + pkgentry=$(find_pkgentry $pkgname) + if [ -z "$pkgentry" ]; then + return 1 + fi + deltas="$pkgentry/deltas" + # create deltas file if it does not already exist + if [ ! -f "$deltas" ]; then + msg2 "$(gettext "Creating 'deltas' db entry...")" + echo -e "%DELTAS%" >>$deltas + fi + # get md5sum and compressed size of package + md5sum="$(openssl dgst -md5 "$deltafile" | awk '{print $NF}')" + csize=$(@SIZECMD@ "$deltafile") + + oldfile=$(xdelta3 printhdr $deltafile | grep "XDELTA filename (source)" | sed 's/.*: *//') + newfile=$(xdelta3 printhdr $deltafile | grep "XDELTA filename (output)" | sed 's/.*: *//') + + if grep -q "$oldfile.*$newfile" $deltas; then + warning "$(gettext "An entry for '%s' already existed")" "$deltafile" + sed -i.backup "/$oldfile.*$newfile/d" $deltas && rm -f $deltas.backup + msg2 "$(gettext "Removing existing entry '%s'...")"
