Subject: spawnebuild: skip previously executed phases
X-Git-Tag: v2.2.0_alpha52~44
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5bc6b9c8767c9a9bea511d7ece98f54e8a873b47;p=portage.git

spawnebuild: skip previously executed phases

This simply checks of $PORTAGE_BUILDDIR/.${EBUILD_PHASE%e}ed and skips
the phase like ebuild.sh would. It preserves a special case for the
install phase with FEATURES=noauto, so that dyn_install in ebuild.sh
continues to work the same for this case.. Also, note that commit
ae9b6cb513c7b29376caecf3b4e52aac452e2b93 preserves the automatic
"recreating WORKDIR" behavior that used to be implemented in
dyn_unpack.
