Description Maciej Mrozowski gentoo-dev

Steps to reproduce:
- install multiple slotted packages - KDE 4.1 is good example (SLOT=4.1 with -kdeprefix so that inter-SLOT upgrade will be applied)
- issue upgrade to KDE 4.2 (SLOT=4.2) - this will applu some blocks and will explicitly cause some packages to be uninstalled (as they are no longer present in 4.2 and wouldn't be uninstalled otherwise)
- terminate process at some point

This will leave (as of now) some duplicated package atoms installed - like (arbitrary example):
kde-base/solid-4.1.4
kde-base/solid-4.2.0
kde-base/libplasmaclock-4.1.4
kde-base/libplasmaclock-4.2.0
as uninstall process for those -4.1.4 has been delayed and upgrade process has been terminated before it got there thus leaving system in a bit inconsistent state. Of course one can fix this by --depclean as 4.1.4 are no longer referenced.

This may not be only inter-SLOT related issue, but just issue related to explicit blocks, are they cause some packages to be explicitly uninistalled.

I haven't seen this problem in a while. Maybe close it as worksforme, I'll reopen if it appears again.

Well, unless you'd like to provide 'atomic installation' feature...

There's this fix for executing uninstalls as soon as possible:

This is a lot less likely to be an issue now that kdeprefix is gone (and all kde-4 packages have moved to SLOT=4).

Haven't seen this in ages. I'll reopen if I ever spot it again.
