Bug 748456 – sys-apps/portage-3.0.44-r1: wrong dependency written in comment by autounmask

• Product: Portage Development
• Status: UNCONFIRMED ---

[Description Nikita Zlobin 2020-10-13 12:23:45 UTC]

I'm in start of standard periodical world rebuild. For now is simple upgrade. I have autounmask on to save time with keywords, and use flag editing.

I got problem with some python packages. Just one example:

# required by dev-python/cffi-1.14.0-r3::gentoo
# required by virtual/python-cffi-1::gentoo[-python_targets_python3_8,python_targets_python3_7,python_targets_python3_6]
# required by dev-python/pycryptodome-3.9.8-r1::gentoo
# required by net-im/gajim-1.2.1::gentoo[python_single_target_python3_7,crypt]
# required by @selected
# required by @world (argument)
# /etc/portage/package.mask/custom.cldx:
#virtual/blas::gentoo
#virtual/cblas::gentoo
#virtual/lapack::gentoo
#sci-libs/lapack-reference::gentoo
#sci-libs/gsl::gentoo
#sci-libs/blas-reference::gentoo
#sci-libs/cblas-reference::gentoo
#app-admin/eselect
#dev-java/icedtea-bin:7
#=media-libs/opencolorio-1.0.9-r4
=dev-python/pycparser-2.20-r2

As you look into ebuilds, dev-python/cffi-1.14.0-r3 doesn't specify minimal version for pycparser, yet it has no python3 support (so no reason to want pycparser-2.20-r2 from overlay).

I'm certain that comment itself doesn't lie, because dev-python/cffi is only installed pycparser dependent.

Reproducible: Always




It happened earlier, though I don't see anything about it among my reports.

I was wrong about exact reason, it's indeed wrong comment.
I did not notice =dev-python/cffi-1.14.3 below.

Here is true reason:
dev-python/cffi:0

[Comment 4 Nikita Zlobin 2021-05-09 13:08:13 UTC]

More exact case, now with linux-headers.
Installed version 5.4-r1, version 5.10 is masked (same as for toolchain, to prevent unexpected toolchain upgrades).

From upgrades still to be done, only pax-utils requires higher version than current (linux-headers-5.8), others are satisfied by version. But report reasoning from autounmask still has misleading requesters:

The following mask changes are necessary to proceed:
 (see "package.unmask" in the portage(5) man page for more details)
# required by virtual/os-headers-0-r2::gentoo
# required by media-libs/zvbi-0.2.35-r1::gentoo
# required by media-video/ffmpeg-4.3.2::gentoo[zvbi]
# required by media-libs/aubio-0.4.9::gentoo[ffmpeg]
# required by media-sound/ardour-6.6-r1::gentoo
# required by @selected
# required by @world (argument)
# /etc/portage/package.mask/00_toolchain:
=sys-kernel/linux-headers-5.10

virtual/os-headers only specified zero slot for headers.

There's even more ridiculous error case:

# emerge -tav1 gimp

These are the packages that would be merged, in reverse order:
