Bug 302005 – sys-apps/portage-2.2_rc61: /usr/lib/portage/pym/portage/sets/__init__.py: ValueError: too many values to unpack

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Jacob Godserv 2010-01-24 04:10:45 UTC]

Latest trunk seems to have this issue as well. I am afraid to install trunk, since I don't know how to recover portage, or what kind of changes have been made since rc61, so I haven't been able to test this in trunk.

This is the error:
Traceback (most recent call last):
  File "/usr/lib/portage/pym/portage/sets/__init__.py", line 187, in <module>
    l, e = sc.getSets()
ValueError: too many values to unpack

The patch will follow shortly.

Reproducible: Always

Steps to Reproduce:
1. emerge -1 '=sys-apps/portage-2.2_rc61' # may or may not be necessary; see above
2. python /usr/lib/portage/pym/portage/sets/__init__.py

Created attachment 217292 [details, diff]
pym/portage/sets/__init__.py patch

Here's the suggested patch. I may be mis-reading something, but it seems to me that the developer made a simple (copy-paste?) goof here, especially since the unneeded variable is never used in the rest of the file.

[Comment 2 Zac Medico 2010-01-24 05:10:13 UTC]

Thanks. In svn r15208 I've removed the whole hunk of code since it's not really needed.

[Comment 3 Jacob Godserv 2010-01-24 05:43:33 UTC]

I was just commenting in #gentoo-portage how nice it is to have some solid information on how portage sees sets. It'd be nice if either the error messages for sets could be improved (for example, dump the set object information like name and description).

I should file another bug report for this, but since this fix directly affects my ability to debug sets, I thought I'd mention it.

[Comment 4 Zac Medico 2010-01-24 06:24:02 UTC]

I guess we can add support to portageq for querying set atoms.

[Comment 5 Jacob Godserv 2010-01-25 01:42:18 UTC]

I've reported a new bug for portage set error messages @ bug #302121.

Is this bug fixed?

[Comment 6 Zac Medico 2010-01-29 21:36:09 UTC]

This is fixed in 2.1.7.17 and 2.2_rc62.

[Comment 7 Jacob Godserv 2010-01-29 21:37:26 UTC]

Awesome, thanks. :)
