Description Karel Srot 2012-06-05 08:20:29 UTC

same bug seems to be present also in rhel5.8

+++ This bug was initially created as a clone of Bug #804120 +++

Description of problem:

Running certain code paths of: yum --security --sec-severity=Critical upgrade result in the plugin running:

'severity' not in notice

...but their was no explicit support for that in the class, and the default way python implements it works like:

1. Can I have element 1.
2. Can I have element 2.
2. Can I have element 3.
2. Can I have element 4.
[...]

...and this will go on forever.

 Quick test, from ipython:

In [2]: import yum.update_md

In [3]: x = yum.update_md.UpdateNotice()

In [4]: 'foo' in x

...fix is a one liner in yum.

Comment 1 RHEL Program Management 2012-06-12 01:22:33 UTC

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

Comment 2 James Antill 2013-04-05 13:50:57 UTC

 The fix is really simple, so I'll ACK this one, but I'm not sure how useful it is given the lateness of RHEL-5 (and that it was discovered internally, and has no customers behind it).

 Might as well close this, given no customer desire to get it fixed and how we are very late in RHEL-5.
 At least the early versions of RHEL-6 yum could be rebuilt on RHEL-5, so if any customer really needs this then the fixed version in rhel-6 is a viable path.
