# Phase function: src_unpack
python-distutils-ng_src_unpack() {
[[ "${PYTHON_OPTIONAL}" =3D "yes" ]] && { use python || return; }
if type python_unpack &> /dev/null; then
# This should not run anything specific to any single Python
# implementation, keep it generic:
python_unpack_all
else
[[ -n ${A} ]] && unpack ${A}
fi
}
I think you meant to write "if type python_unpack_all".
More to the point, I don't actually understand why this function
exists. It doesn't actually do anything that default_src_unpack does
not do already. Exporting it will clobber any vcs eclasses if the
inherit order is wrong.
