Bug 379749 – profile update is not applied to ROOT=... prefix resulting in file collision

• Product: Portage Development
• Status: CONFIRMED ---

[Description Dennis Schridde 2011-08-18 16:05:17 UTC]

Facts:
* profiles/updates/3Q-2011 contains:
move app-editors/gentoo-editor app-misc/editor-wrapper

* packages/app-misc/editor-wrapper-2.tbz2 exists, but I do not know whether it was created by the move mentioned above or whether it was actually build freshly. (If that is important, please hint me how to figure that out.)

* packages/app-editors/gentoo-editor-2.tbz2 does not exist.

Problem:
The move from profile/updates was apparently never executed for my ROOT=... prefixes. This results in portage trying to emerge the binary package of app-misc/editor-wrapper for this prefix, which in turn results in a file collision with the already installed app-editors/gentoo-editor-2.

Reproducible: Always

Another fact:
# ROOT=... emerge --search gentoo-editor
Searching...    
[ Results for search key : gentoo-editor ]
[ Applications found : 1 ]

*  app-editors/gentoo-editor
      Latest version installed: 2

You should be able to apply the moves with emaint like this:

    ROOT=... emaint --fix moveinst

Would that destroy information you would need me to provide to debug this? Or can I safely run that operation without making it impossible to get at the root cause?

[Comment 5 Zac Medico 2011-08-18 16:48:36 UTC]

We don't need any debugging info, since emerge just doesn't support updates for ROOT!=/ at this time. The reason is that information about applied updates is stored in $ROOT/var/cache/edb/mtimedb, and we need to fix emerge to handle it correctly for multiple ROOTs.

Thanks for the explanation and the workaround!
