If package A has a := dependency on package B, then when B is scheduled for upgrade, is it valid for Portage to rebuild A before upgrading B? I'm hitting this case on a couple of my machines, with the perl 5.30.3 to 5.32.1 upgrade. When I run 'emerge -puvDU @world', Portage wants to rebuild several dev-perl/* and virtual/perl-* packages [rR] before building dev-lang/perl [rU]. At best, the initial rebuilds look redundant, but this disagrees with how I understand subslot rebuilds to work. A section of the emerge pretend output is as follows, the full log is attached: > ... (53 other packages, mostly perl things) ... > [ebuild rR ] dev-perl/TimeDate-2.330.0::gentoo 0 KiB > [ebuild rR ] perl-core/File-Temp-0.230.900::gentoo 74 KiB > [ebuild U ] dev-perl/Digest-HMAC-1.30.0-r2::gentoo [1.30.0-r1::gentoo] 0 KiB > [ebuild U ] sys-devel/automake-1.16.3-r1:1.16::gentoo [1.16.2-r1:1.16::gentoo] USE="-test" 1,554 KiB > [ebuild rR ] dev-perl/Module-Build-0.422.400::gentoo USE="-test" 298 KiB > [ebuild rR ] dev-perl/Locale-gettext-1.70.0::gentoo 9 KiB > [ebuild r U ] dev-lang/perl-5.32.1:0/5.32::gentoo [5.30.3:0/5.30::gentoo] USE="berkdb gdbm -debug -doc -ithreads -minimal%" 12,442 KiB > [ebuild U ] dev-vcs/git-2.31.1::gentoo [2.26.3::gentoo] USE="blksha1 curl emacs gpg iconv nls pcre perl threads tk webdav -cgi -cvs -doc -gnome-keyring -highlight -mediawiki -mediawiki-experimental -perforce (-ppcsha1) -subversion -test -xinetd (-pcre-jit%*)" PYTHON_SINGLE_TARGET="python3_8 -python3_7 -python3_9%" 6,740 KiB > [ebuild rR ] dev-perl/IPC-System-Simple-1.250.0::gentoo USE="-test" 0 KiB > ... > The following packages are causing rebuilds: > > (dev-lang/perl-5.32.1:0/5.32::gentoo, ebuild scheduled for merge) causes rebuilds for: > ... > (dev-perl/Locale-gettext-1.70.0:0/0::gentoo, ebuild scheduled for merge) > ... dev-lang/perl-5.32.1 has PDEPEND on some virtual/perl-* packages, but at least I don't see why Locale-gettext couldn't be built after perl. Portage wanted to do this on two of three of my machines. On one where I went ahead with the world upgrade, the upgrade went smoothly, though a subsequent 'emerge -puvDU @world' now wants to rebuild those too-early packages again. On the remaining machine, disabling dynamic deps and adding --changed-deps=y doesn't change the build plan. Portage reports that libxml2 can't be updated due to dependency constraints, not sure if that's related. I'm happy to post the compressed 'emerge --debug' log if that'll help, it's 1.7M. Or maybe this is just a corner case that Portage is handling correctly? Thanks!

The "priority" of perl, when seen by perl modules, may have "satisfied" set to an installed perl of a wrong slot. Compounding this factor with bug #756199 where find_smallest_cycle would select a single node, in this case because the dependency of perl is satisfied and the priority then gets ignored, the "cycle" becomes a perl module alone and gets rebuilt early. I also updated the test from the previous patch to account for this change. No other tests seems affected. For a larger scale test, I reproduced this initially with a stage3 chroot from a Jan 1 2022 stage3 snapshot, and testing in an equivalent dockerfile would work too: FROM gentoo/stage3:amd64-openrc-20220101 RUN emerge-webrsync COPY . /portage Before this patch (USE flags omitted): # cd /portage && bin/emerge -puDN @world 2>&1 | grep -i perl [ebuild U ] app-admin/perl-cleaner-2.30-r1 [2.30] [ebuild rR ] virtual/perl-File-Temp-0.231.100 [ebuild rR ] dev-perl/Locale-gettext-1.70.0-r1 [ebuild rR ] dev-perl/MIME-Charset-1.12.2-r1 [ebuild rR ] dev-perl/Module-Build-0.423.100 [ebuild rR ] dev-perl/Text-CharWidth-0.40.0-r2 [ebuild U ] dev-lang/perl-5.36.0-r2 [5.34.0-r3] [ebuild N ] virtual/perl-CPAN-2.330.0 [ebuild U ] virtual/perl-ExtUtils-MakeMaker-7.640.0 [7.620.0] [ebuild U ] virtual/perl-File-Spec-3.840.0 [3.800.0] [...] After this patch: # cd /portage && bin/emerge -puDN @world 2>&1 | grep -i perl [ebuild U ] app-admin/perl-cleaner-2.30-r1 [2.30] [ebuild U ] dev-lang/perl-5.36.0-r2:0/5.36 [5.34.0-r3:0/5.34] [ebuild N ] virtual/perl-CPAN-2.330.0 [ebuild U ] virtual/perl-ExtUtils-MakeMaker-7.640.0 [7.620.0] [ebuild U ] virtual/perl-Data-Dumper-2.184.0 [2.179.0] [ebuild U ] virtual/perl-File-Spec-3.840.0 [3.800.0] [ebuild U ] virtual/perl-Test-Harness-3.440.0-r1 [3.430.0] [ebuild rR ] dev-perl/Pod-Parser-1.630.0-r1 [ebuild rR ] dev-perl/Text-CharWidth-0.40.0-r2 [ebuild rR ] dev-perl/Text-WrapI18N-0.60.0-r2 [...] Bug: https://bugs.gentoo.org/463976 Bug: https://bugs.gentoo.org/592880 Bug: https://bugs.gentoo.org/596664 Bug: https://bugs.gentoo.org/631490 Bug: https://bugs.gentoo.org/764365 Bug: https://bugs.gentoo.org/793992 Signed-off-by: YiFei Zhu <zhuyifei1999@gmail.com> Closes: https://github.com/gentoo/portage/pull/1055 Signed-off-by: Sam James <sam@gentoo.org> lib/_emerge/depgraph.py | 18 ++++++++++++++++++ lib/portage/tests/resolver/test_perl_rebuild_bug.py | 4 ++-- 2 files changed, 20 insertions(+), 2 deletions(-) https://gitweb.gentoo.org/proj/portage.git/commit/?id=ff457f742b513a65e6609054e5310f8beee488ec commit ff457f742b513a65e6609054e5310f8beee488ec Author: YiFei Zhu <zhuyifei1999@gmail.com> AuthorDate: 2023-06-13 08:08:51 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2023-06-16 03:34:46 +0000 tests: resolver: Test the broken behavior of Perl rebuild bug Bug: https://bugs.gentoo.org/463976 Bug: https://bugs.gentoo.org/592880 Bug: https://bugs.gentoo.org/596664 Bug: https://bugs.gentoo.org/631490 Bug: https://bugs.gentoo.org/764365 Bug: https://bugs.gentoo.org/793992 Signed-off-by: YiFei Zhu <zhuyifei1999@gmail.com> Signed-off-by: Sam James <sam@gentoo.org> .../tests/resolver/test_perl_rebuild_bug.py | 121 +++++++++++++++++++++ 1 file changed, 121 insertions(+)
