Ensure that all USE_EXPAND variables are always exported with filtered USE flags inside, even if none of those flags are declared in IUSE. This is the behavior required for EAPI 5+ by the PMS.
Since the behavior for earlier EAPIs is left undefined and having different behavior would be confusing to users, apply it in earlier EAPIs as well. --- bin/ebuild.sh | 6 ---- pym/portage/package/ebuild/config.py | 55 ++---------------------------------- 2 files changed, 3 insertions(+), 58 deletions(-) diff --git a/bin/ebuild.sh b/bin/ebuild.sh index 5b3146d..edf885f 100755 --- a/bin/ebuild.sh +++ b/bin/ebuild.sh @@ -690,12 +690,6 @@ if ! has "$EBUILD_PHASE" clean cleanrm ; then fi fi -# unset USE_EXPAND variables that contain only the special "*" token -for x in ${USE_EXPAND} ; do - [ "${!x}" == "*" ] && unset ${x} -done -unset x - if has nostrip ${FEATURES} ${RESTRICT} || has strip ${RESTRICT} then export DEBUGBUILD=1 diff --git a/pym/portage/package/ebuild/config.py b/pym/portage/package/ebuild/config.py index 5f19996..d92f5f6 100644 --- a/pym/portage/package/ebuild/config.py +++ b/pym/portage/package/ebuild/config.py @@ -1330,47 +1330,7 @@ class config(object): filtered_var_split.append(x) var_split = filtered_var_split - if var_split: - value = ' '.join(var_split) - else: - # Don't export empty USE_EXPAND vars unless the user config - # exports them as empty.
