It does not gzip the # output tar again but directly extracts to ${WORKDIR} # # It will autodetect for rpm2cpio (included in app-arch/rpm) and if it exists # it will use that instead of the less reliable rpmoffset. This means if a # particular rpm cannot be read using rpmoffset, you just need to put : # # DEPEND="app-arch/rpm" # # in your ebuild and it will install and use rpm2cpio instead. If you wish # to force your ebuild to use rpmoffset in the presence of rpm2cpio, define: # # USE_RPMOFFSET_ONLY="1" USE_RPMOFFSET_ONLY=${USE_RPMOFFSET_ONLY-""} DEPEND=">=app-arch/rpm2targz-9.0-r1" # extracts the contents of the RPM in ${WORKDIR} rpm_unpack() { local rpmfile rpmoff decompcmd rpmfile=$1 if [ -z "${rpmfile}" ]; then return 1 fi if [ -x /usr/bin/rpm2cpio -a -z "${USE_RPMOFFSET_ONLY}" ]; then rpm2cpio ${rpmfile} | cpio -idmu --no-preserve-owner --quiet || return 1 else rpmoff=`rpmoffset < ${rpmfile}` [ -z "${rpmoff}" ] && return 1 decompcmd="gzip -dc" if [ -n "`dd if=${rpmfile} skip=${rpmoff} bs=1 count=3 2>/dev/null | file - | grep bzip2`" ]; then decompcmd="bzip2 -dc" fi dd ibs=${rpmoff} skip=1 if=${rpmfile} 2> /dev/null \ | ${decompcmd} \ | cpio -idmu --no-preserve-owner --quiet || return 1 fi return 0 } rpm_src_unpack() { local x prefix ext myfail OLD_DISTDIR for x in ${A}; do myfail="failure unpacking ${x}" ext=${x##*.} case "$ext" in rpm) echo ">>> Unpacking ${x} to ${WORKDIR}" prefix=${x%.rpm} cd ${WORKDIR} rpm_unpack ${DISTDIR}/${x} || die "${myfail}" # find all tar.gz files and extract for srpms if [ "${prefix##*.}" = "src" ]; then OLD_DISTDIR=${DISTDIR} DISTDIR=${WORKDIR} findopts="* -maxdepth 0 -name *.tar" for t in *.tar.gz *.tgz *.tbz2 *.tar.bz2 *.zip *.ZIP; do findopts="${findopts} -o -name ${t}" done for t in $(find ${findopts} | xargs); do unpack ${t} rm -f ${t} done DISTDIR=${OLD_DISTDIR} fi ;; *) unpack ${x} ;; esac done } EXPORT_FUNCTIONS src_unpack
