Comment 2 Eric Grüttefien 2009-08-06 04:16:20 UTC
Just a smal testcase:

moved veryold emerge.log somewhere and starteded a new merge:

Comment 3 Roger 2009-08-09 22:56:24 UTC

And genlop works here still using my old /var/log/emerge.log

I did notice you installed python-3.1.  Python-3.* will break python-2.* code.

# eselect python list

if python 3.1 is selected, then

# eselect python 2  
Comment 4 Eric Grüttefien 2009-08-10 07:55:15 UTC
doesn't seems to make a differencce :-(

Comment 5 Alex Buell 2010-11-09 22:36:57 UTC
I'm seeing the same problem under two different architecures, x86 and sparc. It is a problem with python :-(
Comment 6 Roger 2010-11-09 22:58:10 UTC
I'm haven't used/installed genlop for the longest time.  After a reinstall, found genlop pulling in 20+ unique dependencies not needed elsewhere on minimalist system.  (Probably quite a few more deps a few months ago.)  They seem to be all perl related packages.
Comment 7 Alex Buell 2010-11-09 23:44:39 UTC
I just discovered that qlop (portage-utils-0.3.1) exhibits the same problem, no merge found when there _is_ one running. It's now clear these two depends on something that no longer exists. 

Hope this helps track down the culprit!
Comment 8 Roger 2010-11-10 00:12:21 UTC

qlop seems to work just fine here.

roger # qlop -cv
 * app-shells/bash-4.1_p9
     started: Tue Nov  9 15:05:44 2010
     elapsed: 7 seconds
     chroot:  /

# qlop -t bash
bash: 313 seconds average for 8 merges

(One thing I did just notice, qlop --current could easily be coded to call the --time function to provide estimated package emerge time.)

As far as this bug, would double check your python install and folder permissions?  Also, just noticed on my last emerge world, /etc/portage/package.mask /etc/portage/package.unmask seem to be being totally ignored now by portage -- files are now merged into /etc/portage/package.keywords -- causing an unwanted temporary downgrade of portage for me.
