cargo.eclass: add cargo_live_src_unpack() This function will allow using 'cargo fetch' during src_unpack Since only new cargo supports vendoring, all live packages will have to depend on >=rust-1.37.0 This enables us to ship live rust packages, cargo fetch will download all crates and vendor them for offline phases. here's an example of src_unpack() src_unpack() { if [[ "${PV}" == *9999* ]]; then git-r3_src_unpack cargo_live_src_unpack else cargo_src_unpack fi } Signed-off-by: Georgy Yakovlev <gyakovlev <AT> gentoo.org> eclass/cargo.eclass | 27 ++++++++++++++++++++++++++- 1 file changed, 26 insertions(+), 1 deletion(-) diff --git a/eclass/cargo.eclass b/eclass/cargo.eclass index b16e0e9d633..44d11cdb838 100644 --- a/eclass/cargo.eclass +++ b/eclass/cargo.eclass @@ -12,7 +12,12 @@ if [[ -z ${_CARGO_ECLASS} ]]; then _CARGO_ECLASS=1 -CARGO_DEPEND="virtual/cargo" +if [[ ${PV} == *9999* ]]; then + # we need at least this for cargo vendor subommand + CARGO_DEPEND=">=virtual/cargo-1.37.0" +else + CARGO_DEPEND="virtual/cargo" +fi case ${EAPI} in 6) DEPEND="${CARGO_DEPEND}";; @@ -97,6 +102,26 @@ cargo_src_unpack() { cargo_gen_config } +# @FUNCTION: cargo_live_src_unpack +# @DESCRIPTION: +# Runs 'cargo fetch' and vendors downloaded crates for offline use, used in live ebuilds + +cargo_live_src_unpack() { + debug-print-function ${FUNCNAME} "$@" + + [[ "${PV}" == *9999* ]] || die "${FUNCNAME} only allowed in live/9999 ebuilds" + [[ "${EBUILD_PHASE}" == unpack ]] || die "${FUNCNAME} only allowed in src_unpack" + + mkdir -p "${S}" || die + + pushd "${S}" > /dev/null || die + CARGO_HOME="${ECARGO_HOME}" cargo fetch || die + CARGO_HOME="${ECARGO_HOME}" cargo vendor "${ECARGO_VENDOR}" || die + popd > /dev/null || die + + cargo_gen_config +} + # @FUNCTION: cargo_gen_config # @DESCRIPTION: # Generate the $CARGO_HOME/config necessary to use our local registry
