<slyfox> looks like portage is too eager at rebuilding even when subslot does not change: $ emerge -avt1 dev-haskell/network These are the packages that would be merged, in reverse order: Calculating dependencies... done!

We may be able handle this case by simply discarding the rebuild backtrack parameters, and re-calculating the graph while remembering to skip the problematic updates.
This is fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=222dfa56e8fb311f4bea54012bdfd5d1a474d56c
This is fixed in 2.1.11.31 and 2.2.0_alpha142.
It looks like we have some remaining cases where _slot_confict_backtrack can add installed packages to the runtime_pkg_mask and trigger unnecessary rebuilds since the code from commit 222dfa56e8fb311f4bea54012bdfd5d1a474d56c does not remove them from runtime_pkg_mask. This example unnecessary rebuild was posted in #gentoo-portage: > These are the packages that would be merged, in order: > > Calculating dependencies . ... .. ...... done! > [ebuild R ] dev-lang/erlang-22.3.4:0/22.3.4::gentoo USE="hipe kpoll ssl systemd wxwidgets -doc -emacs -java -libressl -odbc -sctp -tk" 0 KiB > > Total: 1 package (1 reinstall), Size of downloads: 0 KiB > > WARNING: One or more updates/rebuilds have been skipped due to a dependency conflict: > > app-i18n/unicode-data:0 > > (app-i18n/unicode-data-13.0.0:0/0::gentoo, ebuild scheduled for merge) USE="" ABI_X86="(64)" conflicts with > =app-i18n/unicode-data-12.1* required by (gnome-extra/gucharmap-12.0.1-r1:2.90/2.90::gentoo, installed) USE="introspection -debug -test -vala" ABI_X86="(64)" > ^ ^^^^^ > > dev-lang/erlang:0 > > (dev-lang/erlang-23.0.2:0/23.0.2::gentoo, ebuild scheduled for merge) USE="hipe kpoll ssl systemd wxwidgets -doc -emacs -java -libressl -odbc -sctp -tk" ABI_X86="(64)" conflicts with > >=dev-lang/erlang-21:0/22.3.4=[ssl] required by (dev-lang/elixir-1.10.4:0/0::gentoo, installed) USE="-test" ABI_X86="(64)" > ^^^^^^^^^^ > <dev-lang/erlang-23.0[ssl] required by (net-misc/rabbitmq-server-3.8.4:0/0::gentoo, installed) USE="" ABI_X86="(64)" > ^ ^^^^ > > dev-python/rsa:0 > > (dev-python/rsa-4.2:0/0::gentoo, ebuild scheduled for merge) USE="-test" ABI_X86="(64)" PYTHON_TARGETS="python3_7 -python3_6 -python3_8 -python3_9" conflicts with > <dev-python/rsa-3.5.0.0[python_targets_python3_7(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-),-python_single_target_python3_8(-)] required by (dev-python/awscli-1.18.70:0/0::gentoo, installed) USE="-test" ABI_X86="(64)" PYTHON_TARGETS="python3_7 -python3_6 -python3_8" > ^ ^^^^^^^ > > dev-util/scons:0 > > (dev-util/scons-4.0.1:0/0::gentoo, ebuild scheduled for merge) USE="-doc -test" ABI_X86="(64)" PYTHON_TARGETS="python3_7 -python3_6 -python3_8" conflicts with > dev-util/scons[python_targets_python2_7] required by (games-puzzle/pingus-0.7.6-r2:0/0::gentoo, installed) USE="opengl -music" ABI_X86="(64)"

(In reply to Stephan Menzel from comment #5) > I have been seeing this for many months now and failed at trying to fix it. > Even though it doesn't seem to cause any harm it still feels like something > is off. In order to fix things like this, it's helpful to first have a unit test that demonstrates the problem. That makes it easy to demonstrate when you have a working fix. > Are there any news about a possible fix? No, and I don't have a unit test to demonstrate the problem either.
Our unit test for the case fixed in commit 222dfa56e8fb311f4bea54012bdfd5d1a474d56c is the testSlotConflictRebuild method in this file: https://gitweb.gentoo.org/proj/portage.git/tree/lib/portage/tests/resolver/test_slot_conflict_rebuild.py

This is needed for correct behavior in cases the highest version cannot be installed because an older version is required by some package. This reverts a change related to bug 531656 from commit a9064d08ef4c92a5d0d1bfb3dc8a01b7850812b0, and that change no longer appears to be necessary, since the unit tests related to bug 531656 now pass without it. Due to this change in slot conflict handling, the --changed-slot test case related to bug 456208 will now fail unless we use an @world update to trigger rebuilds, therefore fix it to do so.

They can cause rebuilds, and these rebuilds may be not possible due to reasons such as keywords or masks. In this case, prior to this patch, portage would cancel the downgrade, but the rebuilds would be requested endlessly, because bug 439688's backtrack code does not trigger. To reproduce, on an ACCEPT_KEYWORDS=~amd64 machine, emerge =dev-libs/openssl=3.0.9, dev-util/rustup, and something else that depends on openssl. Then un-accept ~amd64 for openssl and rustup. Prior to this patch, a @world upgrade would cause: These are the packages that would be merged, in order: Calculating dependencies... done!
