Bug 268246 – sys-apps/portage-2.1.6.11: emerge -p --depclean exits with 0 even when it fails

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Pacho Ramos 2009-05-02 08:15:15 UTC]

Now, if I run emerge -p --depclean I get:
 # emerge -p --depclean

 * Depclean may break link level dependencies.  Thus, it is
 * recommended to use a tool such as `revdep-rebuild` (from
 * app-portage/gentoolkit) in order to detect such breakage.
 * 
 * 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, it is often necessary to run `emerge --update
 * --newuse --deep world` prior to depclean.

Calculating dependencies... done!
 * Dependencies could not be completely resolved due to
 * the following required packages not being installed:
 * 
 *   >=virtual/perl-IO-Compress-Bzip2-2.012 pulled in by:
 *     perl-core/Archive-Tar-1.40
 * 
 * Have you forgotten to run `emerge --update --newuse --deep world` prior
 * to depclean? It may be necessary to manually uninstall packages that no longer
 * exist in the portage tree since it may not be possible to satisfy their
 * dependencies.  Also, be aware of the --with-bdeps option that is documented
 * in `man emerge`.

If I run:
# echo $?
0

This is a bit annoying for me because I run some commands with "&&" and I would expect get them not run when depclean fails

[Comment 2 Pacho Ramos 2009-05-02 13:17:40 UTC]

I already knew the "perl" problem, but this is simply for exit status when emerge fails, that it "0" when it should be other one

Thanks

[Comment 3 Sebastian Luther (few) 2009-06-09 19:53:24 UTC]

This is fixed in =sys-apps/portage-2.1.6.13.

[Comment 4 Zac Medico 2009-06-09 20:19:48 UTC]

I don't think this is fixed because afaik action_depclean() always returns success.

On line 14357, unresolved_deps() is called. If this fails, action_depclean() returns 1.

Oh, that's right. Thanks.

[Comment 7 Pacho Ramos 2009-06-10 18:59:57 UTC]

Yes, I confirm the fix as I have see it today and now it behaved properly :-)

Thanks
