[gentoo-user] depclean screw up

[gentoo-user] depclean screw up

[Mike Williams]

Hi,

Check out this wackiness from depclean.
This has had me stumped all day, no matter how many merges, depcleans, 
revdep-rebuilds I try.

It's long...

But, basically, depclean wants to remove packages that equery says have direct 
dependencies.
If I merge all the packages that directly depend on the packages depclean 
wants to unmerge, depclean still wants to remove them!
If I let depclean remove the packages, then run revdep-rebuild, the packages 
it finds broken pull in all the packages depclean removed!

Help, anyone?

equery depends is unfortunately broken.  It does not consider use flag
dependancies.

Examples from your list:
- kdegraphics only depends on imlib if you have the imlib USE flag
set, which you do not.
- cups only depends on gnutls if you have the gnutls USE flag set,
which you do not.

If "emerge -DNuvp" does not want to merge anything, then the depclean
list is the list of packages that are not listed in
/var/lib/portage/world or system, and are also not a dependancy of
something in world or system.

Ahh, now that I didn't know.

gnome-libs does directly depend on imlib though.

That one I saw, and it did add to the confusion.
libsoup does depend on gnutls, and gtkhtml depends on libsoup, and dvdrip 
depends on a version of gtkhtml that depends on libsoup, and dvdrip is in my 
world file.

Been there so many times.
I've worked my own way over the dependencies of these packages, and they 
aren't in world or system, but *are* dependencies of installed world listed 
packages.

But depclean wants to remove gnome-libs also, so this doesn't count...

Well, yes, this would be a problem.  Try an "emerge --metadata" to
regenerate the portage cache.  This may help.  Otherwise, please post
your emerge --info.

Yep, bad example. I've got rid of both gnome-libs and imlib.

Already tried removing the entire cache, and re-syncing (from a different 
mirror than I normally use).

gtkhtml-3.10.2 needs >=gnome-base/gail-1.1, and >=net-libs/libsoup-2.1.6 to 
run and compile (RDEPEND and DEPEND). libsoup-2.2.94 with USE=ssl needs 
>=net-libs/gnutls-1 to run and compile. Finally gnutls-1.2.10 needs those 3 
to run and compile.
After merging gtkhtml-3.10.2, and it's dependencies, and it's dependencies 
dependencies (as above), depclean wants to remove them again!

Well I don't see anything obviously wrong.  I would probably take a
look at the output of
"emerge --debug --depclean --pretend world", and look for
net-libs/libsoup or gnome-base/gail.  Both of them should appear as
dependancies of something.  At the very least, they should appear
under gtkhtml.  You might save that output (it will be large!), to
attach to the bug report if requested.

Just some quick notes on reading the debug output:

Depstring: lines are the combined dependancy string from the ebuild.
These should show libsoup and gail for gtkhtml.

Candidates: lines are for dependancies that need to be added as a
result of evaluating depstring.  Once a package is added to the
dependancy tree, it will not be a candidate again for any other
package.  So libsoup and gail should show up in exactly one Candidates
line, but not necessarily for gtkhml.  In fact, gtkhtml will not show
a Candidates line if all dependancies are already part of the tree.

HTH,
-Richard

Ha! Got it!
Searching over that output, that I had never really thought about before, I 
found the answer.
gimp depends on gtkhtml-2*, which at it's highest stable release (2.6.3) 
depends on gail if USE=accessibility.
dvdrip depends on gtkhtml, which at it's highest stable release (3.10.2) 
unconditionally depends on gail.
I had both gtkhtml (3.10.2) and gtkhtml-2* (2.6.3) installed.

media-gfx/gimp-2.2.12 comes before media-video/dvdrip-0.97.10, gimps gtkhtml 
depstring became a candidate, so dvdrips dependency was being ignored!
Removing both versions of gtkhtml, and merging gimp then dvdrip separately has 
apparently sorted it.
depclean has removed gail, libsoup, and their dependencies, and my dynamic 
linking remains consistant.

Thanks

This is equivalent to fixing low oil pressure in your car by
