Bug 150585 – packages masked by nothing

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Marijn Schouten (RETIRED) 2006-10-09 08:24:36 UTC]

I noticed today that an "emerge -uDp world" wanted to emerge gentoo-sources, but I do not have gentoo-sources installed. -t shows that alsa-lib wanted it. It wants a kernel and emerge thinks my vanilla-sources are all masked. This is because I have:

<sys-kernel/vanilla-sources-2.6.18
<sys-kernel/gentoo-sources-2.6.18

in package.mask, and in package.keywords

sys-kernel/vanilla-sources -~amd64
=sys-kernel/vanilla-sources-2.6.18

Output of "emerge -puDt alsa-lib"

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

Calculating dependencies... done!
[nomerge      ] media-libs/alsa-lib-1.0.13
[ebuild  N    ]  sys-kernel/gentoo-sources-2.6.18  USE="-build -symlink (-ultra1)"

when disabling the mask on vanilla:
#<sys-kernel/vanilla-sources-2.6.18
it gives:

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

Calculating dependencies... done!
[nomerge      ] media-libs/alsa-lib-1.0.13
[ebuild  NS   ]  sys-kernel/vanilla-sources-2.6.16.19  USE="-build -symlink"

when I mask vanilla-sources again and try to emerge it
emerge -p vanilla-sources

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

[Comment 1 Jakub Moc (RETIRED) 2006-10-09 11:57:26 UTC]

This is not a bug...

sys-kernel/vanilla-sources -~amd64 in package.keywords + ~amd64 in ebuild keywords produces masked by "nothing", since you've "nullified" the keywords. All other versions are package.masked, so there's nothing available.

[Comment 2 Marijn Schouten (RETIRED) 2006-10-09 12:13:36 UTC]

#only accept stable vanilla-sources:
sys-kernel/vanilla-sources -~amd64

#accept unstable vanilla-sources-2.6.18:
=sys-kernel/vanilla-sources-2.6.18

Combined with ~amd64 keyword in vanilla-sources-2.6.18 ebuild should result in an acceptable vanilla-sources-2.6.18, or at least in an unacceptable vanilla-sources-2.6.18 which is masked by ~amd64. But masked by nothing? No.

[Comment 3 Simon Stelling (RETIRED) 2006-10-10 00:35:03 UTC]

-~amd64 is a strange kind of syntax to say at least. What exactly do you want to express with that?

man portage

<snip>
Example:
# only use stable mplayer
media-video/mplayer -~x86
</snip>

Well, it overrides all ~arch keywords, so subsequently accepting ~arch for a particular version has no effect. 

<sys-kernel/vanilla-sources-2.6.18 -~amd64
~sys-kernel/vanilla-sources-2.6.18
>sys-kernel/vanilla-sources-2.6.18 -~amd64

in package.keywords does what the reporter expects.

[Comment 5 Zac Medico 2006-11-22 19:17:18 UTC]

In svn r5121, I've stacked package.keywords incrementally so that -keyword works as expected for any incremental variable.  This brings the gvisible and getmaskingstatus logic into sync so that the confusing (masked by: ) message will not be generated in cases where package.keywords contains -keyword followed by keyword.

You do realize that the only way to match -arch (which is stupid in keywords, but there) is via -* now, right?

Now I know. Thanks. :)

In svn r5123 it's fixed to allow those to be matched.

This has been released in 2.1.2_rc2-r2.
