[gentoo-user] emerge BUG?

Hi Gentoo users,

Looks like I've encountered a bug in emerge.
I do a sync, some updated packages are displayed, but emerge -avDu 
@world doesn't see some of them, though I don't have them masked.

A today's example:

=======

# eix-sync
[ ... ]
[U]   == net-misc/youtube-dl (2013.11.25.1@26.11.2013; (~)2013.12.11.2 
-> (~)2013.12.17.2): Download videos from YouTube.com (and mores sites...)
[U]   == sys-libs/timezone-data (2013h@20.11.2013; (~)2013h -> 
(~)2013i): Timezone data (/usr/share/zoneinfo) and utilities 
(tzselect/zic/zdump)
[ ... ]
# emerge -avDu @world

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

Calculating dependencies... done!
[ebuild     U  ] sys-libs/timezone-data-2013i [2013h] USE="-nls" 383 kB
[ebuild     U  ] dev-libs/libmemcached-1.0.17 [1.0.14] USE="libevent 
-debug -hsieh -static-libs" 0 kB

Total: 2 packages (2 upgrades), Size of downloads: 383 kB

Would you like to merge these packages? [Yes/No]
#

=====

There are I think over 100 packages to be updated in total, including 
the whole KDE.

When I specify a package instead of @world, it seems to work correctly:

=====
# emerge -avDu kdm

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

Calculating dependencies... done!
[ebuild     U  ] sys-libs/timezone-data-2013i [2013h] USE="-nls" 383 kB
[ebuild     U  ] kde-base/kcheckpass-4.11.4:4 [4.10.5:4] USE="pam

[ebuild     U  ] kde-base/libkonq-4.12.0:4 [4.10.5:4] USE="(-aqua)

(-aqua) -debug -handbook -kerberos -systemd%" 0 kB

Total: 7 packages (7 upgrades), Size of downloads: 24,067 kB

Would you like to merge these packages? [Yes/No]
=====

I rebuilt portage to no avail.
What can it be or should I file a bug?

The output of `emerge --info` is attached.

Hm, really, it's almost empty except for the last packages I have added 
yesterday... So that's clearly not an emerge bug, but ... Could anything 
mess it up?
I have copied the system to a new HDD recently and done an `emerge 
@world`, too, and everything went OK.

Plenty, with the favourite being user error. If the packages aren't in
world nor depended on by something n world, portage will not upgrade them.

OK as in everything you expected to build built? Or OK as in no error
messages appeared? Your first step would be to restore the world file
from the old drive, adding the entries from the current version.

Including /var?

If the correct version of the world file is lost, you may want to try
to regenerate it with `regenworld'. This utility will search old
emerge log files (did you copy it from old HDD?) If old emerge log
files are lost too, then the script from [1] could help to recover
some (major) part of the world file entries.

The former. When I do an eix-sync, I expect that emerge -Du @world 
updates every package listed with the U-mark.
There are no error messages anyway.

I'll do this, but now I'm just wondering how I ended up with an empty 
world file.

Yes, I have /var on root fs and just rsync'ed.

Thanks, I think a pretty easy way to regenerate @world is to edit the 
output of `emerge -pv --deplean`. At least I'm going to try this.

That shows nothing, except that the packages it did update had no errors.
You haven't said whether it emerged everything it should have, which it
probably did not.

Did you copy the original over in the first place? Did you try adding

That will add dependencies to world, which is a bad thing. You can use
depclean to produce a list and then remove everything but the software
you actually use. Then pass that list to emerge -n.

No, I never had to touch the world file directly (until today), feeling 
that emerge {-n|-1} is enough. I've even forgotten that it exists :)

Thank you, Neil. That's what I did. (Though I actually thought before 
that emerge --depclean shows only top-level packages i.e. those without 
any directly dependent packages. And in fact it shows the whole subtrees.)

I'll be more careful now.
