In the old times, eutils.eclass used to be inherited by almost all
ebuilds, mainly for the epatch function. Today, this is often no
longer needed since the package manager provides eapply() in EAPI 6
and later.
So, with introduction of EAPI 7, we had already moved most of the
functions in eutils.eclass to more specific eclasses. The hope back
then was that usage of eutils would further dwindle, and that the
eclass might be kept as a collection of small tools that don't fit
anywhere else.
Looking at the numbers today, I find these numbers of ebuilds
inheriting eutils.eclass:
37.6 % (3765 of 10013) in EAPI 6
38.3 % (6334 of 16546) in EAPI 7
Which means that there is no visible reduction. Even worse, of the
6334 ebuilds inheriting eutils in EAPI 7, only 140 actually call any
of its remaining functions.
Presumably many of the above inherits are caused by eutils being
indirectly inherited from other eclasses. Which means that ebuild
maintainers don't have any incentive to act (after all, their ebuilds
_don't_ inherit eutils). OTOH, eclass maintainers don't dare to remove
the eutils inherit, because it could potentially break ebuilds that
rely on indirect inheritance.
I think the only way to get out of this is to phase out eutils.eclass
entirely, by moving its remaining functions to other eclasses, or
deprecate them, as follows:
edos2unix: split out to new edos2unix.eclass
make_wrapper: split out to new wrapper.eclass
strip-linguas: move to l10n.eclass
emktemp: deprecate (create file in ${T} instead)
use_in_iuse: deprecate (only used in eclasses, where it can be inlined)
Please review the following series of patches.
