Description Petteri Räty (RETIRED) gentoo-dev 2007-03-19 21:16:07 UTC
pena xo # emerge -pvt gst-plugins-dvdread

These are the packages that would be merged, in reverse order:

Calculating dependencies... done!
[nomerge      ] media-plugins/gst-plugins-dvdread-0.10.4
[nomerge      ]  media-libs/gst-plugins-base-0.10.12  USE="alsa esd xv -X -debug -oss"
[ebuild  N    ]   media-plugins/gst-plugins-esd-0.10.5  0 kB
[ebuild  N    ]   media-plugins/gst-plugins-xvideo-0.10.11  0 kB
[ebuild  N    ]   media-plugins/gst-plugins-alsa-0.10.12  0 kB
[ebuild  N    ] media-plugins/gst-plugins-dvdread-0.10.4  0 kB
[ebuild  N    ]  media-libs/gst-plugins-base-0.10.12  USE="alsa esd xv -X -debug -oss" 0 kB

As we see in this case it would be correct to just replace nomerge with the two last ones.

Then merge list wouldn't be telling you the exact merge order, though (bug 158100).

Well then I have one bug for you:

These are the packages that would be merged, in reverse order:

They are in order aren't they?

Hmm?  Given the output shown in comment #0, the merge order would be the order show for "[ebuild  N    ]" packages, read from bottom to top (it's reversed because without --tree the order reads from top to bottom).
Comment 4 Zac Medico gentoo-dev 2007-03-19 23:53:20 UTC
If you're saying that the "[nomerge      ]" nodes shouldn't be shown, then I'm not sure how we can do that and still meet the main goal of --tree which is to show dependency relationships.  I'm open to suggestions if you can think of a better way to display a PDEPEND relationship while still displaying the actual merge order.  It's unfortunate that packages are displayed more than once in cases like this, but given the way that the --tree display works, how else can dependency relationships and merge order be displayed simultaneously?

The current behavior is just fine.
