Description Nikos Chantziaras 2019-09-08 14:12:40 UTC
For about a month now, portage will emerge dev-lang/vala-0.44.7 when doing 'emerge -uDN @world' only to unmerge it again when doing 'emerge --depclean'. The depclean step only sometimes wants to unmerge it though. These are two consecutive runs of 'emerge --depclean'. There are no other commands in between:

======================================

$ emerge -p --depclean

 * Always study the list of packages to be cleaned for any obvious
 * mistakes. Packages that are part of the world set will always
 * be kept.  They can be manually added to this set with
 * `emerge --noreplace <atom>`.  Packages that are listed in
 * package.provided (see portage(5)) will be removed by
 * depclean, even if they are part of the world set.
 * 
 * As a safety measure, depclean will not remove any packages
 * unless *all* required dependencies have been resolved.  As a
 * consequence of this, it often becomes necessary to run 
 * `emerge --update --newuse --deep @world` prior to depclean.

Calculating dependencies... done!
>>> No packages selected for removal by depclean
>>> To see reverse dependencies, use --verbose

>>> These are the packages that would be unmerged:

 dev-lang/vala
    selected: 0.44.7 
   protected: none 
     omitted: 0.42.7 

All selected packages: =dev-lang/vala-0.44.7

>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.

Packages installed:   1312
Packages in world:    157
Packages in system:   43
Required packages:    1311
Number to remove:     1

======================================

Nothing changed between these two invocations. 'emerge --depclean' is erratic on whether to unmerge this package or not.

emerge -pv --depclean (doesn't unmerge)

This is the verbose log of 'emerge -pv --depclean' when it comes up empty and doesn't want to remove vala.

emerge -pv --depclean (wants to unmerge)

And this is the verbose log of when it does want to unmerge vala.
Comment 4 Zac Medico gentoo-dev 2019-09-08 21:56:54 UTC
The dev-lang/vala-0.44.7 instance is optional, pulled in by dependencies like this from vala.eclass $(vala_depend):

> || ( dev-lang/vala:0.46[vapigen(+)] dev-lang/vala:0.44[vapigen(+)] dev-lang/vala:0.42[vapigen(+)] dev-lang/vala:0.40[vapigen(+)] dev-lang/vala:0.36[vapigen(+)] )

Meanwhile the dev-lang/vala-0.42.7 instance is required by gnome-base/dconf-editor-3.30.2 since it constrains $(vala_depend) like this:

> VALA_MIN_API_VERSION="0.40"
> VALA_MAX_API_VERSION="0.42"
> || ( dev-lang/vala:0.42 dev-lang/vala:0.40 )
Comment 5 Zac Medico gentoo-dev 2020-01-19 07:30:18 UTC
The changes for bug 701996 may have influenced the behavior for vala dependencies, given reports like bug 702806 and bug 705700.
