Bug 455344 – sub-slot atom not calculated properly after "emerge --keep-going resumes"

• Status: RESOLVED DUPLICATE of bug 456340
• Product: Portage Development

[Description Alan McKinnon 2013-02-03 21:01:03 UTC]

Not sure if this really is a bug or not. I have read the subslot specs here:

http://devmanual.gentoo.org/ebuild-writing/eapi/index.html

Portage version here is portage-2.2.0_alpha161 on ~amd64

While attempting "emerge -e --keep-going @world" I twice encountered packages failing. Both times when the depgraph was recalculated I got vast amounts of error text like this, and the sub-slot error was both times with icu:

 *   (u'ebuild', u'/', u'x11-themes/tango-icon-theme-extras-0.1.0-r1', u'merge')
 *   (u'ebuild', u'/', u'x11-themes/nou-icon-theme-09.02.08', u'merge')
 *   (u'ebuild', u'/', u'www-plugins/kaffeine-mozilla-plugin-0.2', u'merge')
 *   (u'ebuild', u'/', u'media-video/lxdvdrip-1.76', u'merge')
 * 
 * One or more packages are either masked or have missing dependencies:
 * 
 *   >=dev-libs/icu-49:0/50= pulled in by:
 *     (x11-libs/qt-core-4.8.4-r1::gentoo, installed)

There were many more than 4 packages in the first part - basically everything that --keep-going picked up.

qt-core has this DEPEND:

        icu? ( >=dev-libs/icu-49:= )

My Qt is linked to this icu version:

        libicuuc.so.50 => /usr/lib64/libicuuc.so.50 (0x00007fa3a952c000)

But no version of icu in the tree provides that soname, as shown by eix:

     Available versions:  49.1.2 (~)50.1-r1(0/50.1) (~)50.1-r2(0/50.1) (~)50.1.1(0/50.1.1) {debug doc examples static-libs}
     Installed versions:  50.1.1(09:40:50 15/01/2013)(-debug -doc -examples -static-libs)

My understanding of sub-slots is that portage should have included icu in the depgraph to be rebuilt after --keep-going kicked in, somehow it did not do this.

qt-core at this stage had been built and merged, icu had not.

Reproducible: Always

Steps to Reproduce:
1. have installed qt-core-4.8.4-r1 and icu-50.1.1
2. emerge -e --keep-going @world
3. wait for qt-core to be emerged successfully then cause any old arbitrary ebuild to fail requiring --keep-going to work
Actual Results:  
Calculating dependencies failed

Expected Results:  
Calculating dependencies should have succeeded and remainder of @world should have been emerged

This may have something in common with bug #456340, since these unresolved "built" slot-operator atoms tend to show up when dependency resolution fails due to other unresolved conflicts.

I really couldn't say either way and I'm not really willing to jump into the code to have an opinion on it :-)

I'll go with your judgement on this.
