[gentoo-dev] [PATCH 05/10] xdg.eclass: make EAPI 7 ready

[Marty E. Plummer]

Add dev-util/desktop-file-utils and x11-misc/shared-mime-info to BDEPEND
as a number of executables which will need to be executed on the build
host are included in them.

[gentoo-dev] [PATCH 00/10] {gnome2,xdg}{,-utils}.eclass: EAPI 7 work

[Marty E. Plummer]

Round four. I think I've finally got everything covered properly.
Flipped a lot of has ${EAPI} 6 stuff to [[ ${EAPI:-0} == [012345] ]]
negations as the former version would require adding new EAPI versions
until the end of time. This way you have a finite list of unsupported
EAPIs

Use ${EROOT%/} whereever possible, as most of the directories and files
used in conjunction with it have a leading /; add missing leading /
where apropriate.

Drop EAPI 0-2 support as no in-tree ebuilds use it to simplify the
ROOT/EROOT/BROOT logic.

Use BROOT to specify path to executable files, setting that to EROOT
when not EAPI 7

[Marty E. Plummer]

Add dev-util/desktop-file-utils and x11-misc/shared-mime-info to BDEPEND
as a number of executables which will need to be executed on the build
host are included in them.

Are these also needed in DEPEND? If not, you should set DEPEND="" in
EAPI 7.

Technically, they don't belong in either because they're run
in pkg_post* phases only.

Huh. well, should there not be some way to specify that they are needed

gnome2.eclass would also need to fix this regression in eapi6 (https://bugs.gent

Good to know, I could probably look into that after this gets fully
approved, since I don't want to juggle too many patches with that many
different goals.

According to this, if I read it right, pkg_{pre,post}{inst,rm} deps
should go into PDEPEND; is that still correct in terms of EAPI7 and
such?

This would be a good candidate for an eqawarn message. Not sure how
many people will catch this deprecation in the documentation.

Later patch in the series causes this function to error out on EAPI 7+,
along with a message. I had previously had the same idea, but the ml
thought it would be a bad idea for n amount of currently working ebuilds
to just start yelling out of nowhere. Just force the migration when
updating to EAPI 7 and we're good :)
