[gentoo-user] What does emerge status R mean?

[n952162]

Why does portage want to build this:

[ebuild   R    ] x11-apps/xmodmap-1.0.10::gentoo 0 KiB

given this, already installed:

/var/db/pkg/x11-apps/xmodmap-1.0.10/xmodmap-1.0.10.ebuild

and these on my binary server (which is apparently not working properly
for reasons I'm trying to track down):

      binpkgs/x11-apps/xmodmap-1.0.10.tbz2
      distfiles/xmodmap-1.0.10.tar.bz2

When I remove these options, it doesn't want to anymore:

     #  --changed-use \
     #  --changed-deps \
     #  --newuse \
     #  --backtrack=100 \
     #  --deep \

Which option was it, I wonder, which triggered the build, and would it
bring me anything?

The options still used are:

emerge \
   --getbinpkg y \
   -v \
   --tree \
   --update \
   --noreplace \
   --verbose-conflicts \
   --keep-going \
   --with-bdeps=y \
   @world

My guess is that one of the USE flags changed.  Compare which USE flags 
is it currently installed with and which it wants for the reinstall.  It 
might even be that a USE flag changed in the ebuild, even if it won't 
actually change what gets installed. (--changed-use vs --new-use)

--changed-use would show the changed USE flag in the output, so it is
probably --changed-deps. The emerge man page explains just what the flag
does.

Incidentally, there is no point in using --newuse and --changed-use, the
former is a superset of the latter. I'd use only --changed-use to avoid
unnecessary rebuilds.

The R status means REBUILD. Usually, if it's an @world it's pulling that 
in because something about that package changed and so it needs to 
rebuild it. The --noreplace option would block that if portage didn't 
think it was needed. Based on your options, I'd say that it's probably a 
USE flag was changed. I don't use binpkgs myself, preferring to compile 
except in certain circumstances (can we say RUST!?) that I need to use a 
-bin variant. You can try without it, but I recommend leaving your 
change-use and newuse flags in place and letting the system rebuild xmodmap.

There are no use flags defined for any of the packages I did a random
check for, either on the server or the client.  I am worried that it is
as you say: that the ebuild has a change of USE flags, which, of course,
has nothing to do with me, the user.
I wish dearly that I could find a print out of the reasons why a package
is rejected, listing new and old USE flags, for example.

I haven't been able to find that display yet.  I have found this:

  * Messages for package virtual/dev-manager-0-r2:
  * emerge --keep-going: virtual/dev-manager-0-r2 dropped because it
requires
  * sys-apps/busybox[mdev]

Is this what you're referring to?  In one build, I have tons of these,
but in a way that's confusing me now, they refer to packages that seem
to have been inexplicably dropped.

Yes, thank you, but neither the server nor the client have any USE flags
for that package defined.  And the package has to be pretty stable by
now  ;-)

As already stated, any USE flag changes would appear in the emerge
output, this is most likely caused by --changed-deps. Try with
--changed-use but without --changed-deps to see.

I have introduced that into my build script.  But, if it's as you say,
the one is a subset of the other, it should have no effect on the
output, right?

--changed-use is a subset of --newuse. --changed-deps is separate.

All packages have USE flags defined somewhere even if you haven't
defined any yourself.  Some are defined in profiles, some are defined
elsewhere.  When I do updates, I see changes to USE flags all the time
that were changed by the profile, the maintainer in the ebuild or
somewhere else.  After all, if a package doesn't have the USE flags
defined somewhere, emerge won't know what USE flags to include or
exclude support for.

Ah, I oversaw that.

Ah. why would I want to have --changed-deps anyway?  That suddenly seems
silly.

It's unfortunate, if there's no explanatory display if a package got
disqualified for that reason.

But if I don't specify that I want something specific, why should
portage say, this package has internal differences to the old package, I
better not install it?

If you want to have a binhost, then --changed-deps will become
"necessary" at some point. Let me draw you a picture, where a binhost
would fail to provide the correct package:
 - Binhost builds on day 1 package XYZ
 - computer that would merge with packages from binhost is NOT updated
 - the dependencies are changed on day 2
 - Binhost does NOT rebuild, because you do not have --changed-deps
   enabled on day 2
 - Computer that merges from the binhost is updated on day 2 but will
   NOT use the binary package from binhost, because the dependencies do
   not match
There are flags to ignore dependency mismatches, but the default would
just not use the binary package.

Okay, the point is, there's some package on my system that doesn't match
what the new version of the depending package requires?  Or, just that
there's a dependency change at all?

If the former, but there's a old version of the needed packet, will
portage link with the old version?

I t hink you are confusing enabled USE flags, with package USE flags. A
package can have 0 USE flags (e.g. x11-apps/xmodmap, and many more).
Enabled USE flags on the other hand are defined by user config files and
profiles and by the package itself (i.e. they could be enabled by
default).
So there can very well be packages that have 0 USE flags, and xmodmap
is one of them.
The "problem" here is most probably a changed dependency. The
dependencies (as defined in the ebuild) under which the package was
built on the binhost have changed in the meantime in the ebuild file
(without a revbump/version bump), and if the binhost has not enabled
the flag "--changed-deps", it did not update the package to the new
dependencies.
If you really want to debug this, you could do a diff of the files
/var/db/pkg/x11-apps/xmodmap-1.0.10/xmodmap-1.0.10.ebuild
/usr/portage/x11-apps/xmodmap/xmodmap-1.0.10.ebuild
(or whatever your portage root directory is, I'm still using
/usr/portage). That diff should be on the binhost!

What does changed-deps mean, actually?

        --changed-deps [ y | n ]
               Tells  emerge  to  replace  installed  packages for which
the corresponding
               ebuild dependencies have changed since the packages were
built. ...

I presume it means that a package needed XYZ before, but now needs
XYZZ.  If I don't specify --changed-deps, that I might get a run-time
resolution problem.

Or, does it mean that the package specified XYZ.1 in an excess of
precision and the new version specifies XYZ.3?

I just ran into this:

--binpkg-changed-deps [ y | n ]
               Tells  emerge  to  ignore binary packages for which the
corresponding ebuild
               dependencies have changed since the packages were built. 
In order  to  help
               avoid  issues with resolving inconsistent dependencies,
this option is auto-
               matically enabled unless the --usepkgonly option is
enabled.  Behavior  with
               respect to changed build-time dependencies is controlled
by the --with-bdeps
               option.

But I haven't figured out what it means yet.  In particular, what all
the stated implications mean.

Changed dependencies means any change in the *.ebuild file with respect
to the variables DEPEND/BDEPEND/RDEPEND/PDEPEND, e.g. version of a
dependent package has changed, new package was added as dependency, a
package was removed as dependency. All are dependency changes. If the
changed *.ebuild file is commited to the portage tree WITHOUT a
version-bump/revision-bump, then emerge would NOT rebuild the package,
unless --changed-deps is given as an argument.

This would be the option to ignore dependency mismatches of what the
binary package claims its dependencies are (which you could see  in
$PKGDIR/Packages), and what the resolved dependencies are according to
the *.ebuild file as portage is seeing it right now.
