Bug 515584 – sys-apps/portage: doesn't suggest autounmasking further of || () deps if the first one is USE-masked

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Michał Górny 2014-06-28 10:24:21 UTC]

Consider an ~amd64 ebuild that does:

RDEPEND="
    || (
        sys-libs/zlib[abi_ppc_32(-)]
        sys-libs/zlib[abi_x86_32(-)]
    )
"

If abi_x86_32 dep goes first, --autounmask suggest enabling abi_x86_32 on zlib. If it goes second, portage stops at:

emerge: there are no ebuilds to satisfy "sys-libs/zlib[abi_ppc_32(-)]".
(dependency required by "dev-libs/libblah-0::mgorny" [ebuild])
(dependency required by "libblah" [argument])

If abi_x86_32 is already in package.use (or global USE), portage correctly adds zlib rebuild to depgraph.

So, we need depzapdeps to prefer choices that require enabling of unmasked flags over choices that require enabling of masked flags.
