Description Toralf Förster gentoo-dev

It would be nice if the fetch would be done in this case:


mr-fox ~ # emerge -f dev-libs/libressl net-misc/openssh net-misc/wget

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

Calculating dependencies  .... done!

 * Error: circular dependencies:

(dev-db/sqlite-3.30.1:3/3::gentoo, ebuild scheduled for merge) depends on
 (dev-libs/icu-65.1:0/65.1::gentoo, ebuild scheduled for merge) (buildtime_slot_op)
  (dev-lang/python-3.7.6:3.7/3.7m::gentoo, ebuild scheduled for merge) (buildtime)
   (dev-db/sqlite-3.30.1:3/3::gentoo, ebuild scheduled for merge) (buildtime_slot_op)

It might be possible to break this cycle
by applying any of the following changes:
- dev-lang/python-3.7.6 (Change USE: -sqlite)
- dev-db/sqlite-3.30.1 (Change USE: -icu)

Note that this change can be reverted, once the package has been installed.




emerge might spew the warning but should continue.

The problem is that the solution for the circular deps may affect the files downloaded (like bug 429926).

Unless we greedily downloaded as much as possible, I don't think we can fix this.
