[gentoo-portage-dev] [PATCH 1/2] portage.package.ebuild.config: Rename iuse_implicit -> iuse_effective

[gentoo-portage-dev] [PATCH 1/2] portage.package.ebuild.config: Rename iuse_implicit -> iuse_effective

[Michał Górny]

Rename the iuse_implicit variable used in USE_EXPAND handling to
iuse_effective, since that is what is actually passed there. Correct
naming makes figuring out what the function does much easier.

[gentoo-portage-dev] [PATCH 2/2] ebuild.config: Fix filtering all USE_EXPAND variables in EAPI 5+

[Michał Górny]

Ensure that all USE_EXPAND variables are properly filtered and exported
in EAPI 5 and newer, as required by the PMS. This includes exporting
an empty value if no matching flag is provided in IUSE.

After some thinking, I'll prepare another patch that applies the change
to all EAPIs. The behavior for earlier EAPIs is implementation-defined
by PMS and having it inconsistent will only confuse users.
