(even though I answered 'n' to emerge question, ie. like --pretend) I can confirm that after chaning like 10 ebuilds 's PYTHON_COMPAT from 3_7 to 3_8 , emerge now no longer wants to pull in python 3.7.6 # time emerge --verbose --tree --deep --with-bdeps=y --changed-use --newuse --ask --complete-graph=y --update @world --jobs=1 --pretend These are the packages that would be merged, in reverse order: Calculating dependencies... done! Total: 0 packages, Size of downloads: 0 KiB and depclean has nothing to clean. thus, Comment 8 is correct. PYTHON_COMPAT pythons(well only 3_7 is missing for me) are being pulled by `emerge --deep --with-bdeps=y --update @world` and then cleaned by `emerge --depclean -av`, then again pulled if I redo. the issue doesn't happen with =sys-apps/portage-2.3.69 =sys-apps/portage-2.3.84-r1 happens with: =sys-apps/portage-2.3.86 =sys-apps/portage-9999 (which is at 2.3.86 currently) also doesn't happen with: =sys-apps/portage-2.3.85 (which is a copied ebuild of 2.3.86, without any changes, named /var/db/repos/gentoo/sys-apps/portage/portage-2.3.85.ebuild) # emerge --version Portage 2.3.85 (python 3.6.10-final-0, default/linux/amd64/17.1, gcc-9.2.0, glibc-2.30-r3, 5.4.15-gentoo-x86_64 x86_64) so the issue was introduced in portage 2.3.86 my tests indicate this is the commit that introduced this issue: https://github.com/gentoo/portage/commit/f7d83d75c6b05a16ef07473917082dbd0cd9955c the issue being(ie. to summarize) that: `# emerge --deep --update --with-bdeps=y @world` pulls in python 3.7.6 unnecessarily, which is then removed by `emerge -av --depclean`, only to be pulled again on next update attempt. --with-bdeps=n it doesn't pull it without --deep also doesn't pull it I've got an idea for a fix which I've posted here: https://github.com/gentoo/portage/pull/501#discussion_r373132507 We should be able to correct the problem by using the all_installed_slots attribute, for symmetry with the action that installs the new python slot.

This solves the test case for bug 707108, where depclean eliminated a new slot of python that had been pulled in by a world update. This should also prevent non-deterministic elimination of the latest vala slot that was reported in bug 693790. NOTE: There's a common perception (expressed in bug 705700) that emerge is pulling in an "unecessary" python slot in cases when that python slot is not enabled in PYTHON_TARGETS. However, the so-called "unnecessary" slot is practically indistinguishable from a desirable upgrade such as the missed llvm slot upgrade that was reported in bug 706278. Therefore, be advised that emerge must pull in the highest visible slot (regardless of PYTHON_TARGETS) in order to ensure that a desirable upgrade is not missed.
