Description Matej Kollar 2013-01-18 16:08:36 UTC

Sinscription-manager-s yum plugin prints warning to stdout instead of stderr.

Description of problem:

When invoking yum with subscription-manager, it prints message about not being registered
to stdout instead of stderr. This is confusing mainly for scripts processing output
of yum.

Version-Release number of selected component (if applicable):

# rpm -q subscription-manager 
subscription-manager-1.1.22-1.el6.x86_64

How reproducible: always/deterministic

Steps to Reproduce:

  1. Make sure you are unregistered.
  2. # yum repolist > stdout.log 2> stderr.log
  
Actual results:

  > # cat stdout.log
  > Loaded plugins: product-id, rhnplugin, security, subscription-manager
  > This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
  ...
  > #cat stderr.log
  > This system is not registered with RHN Classic or RHN Satellite.
  > You can use rhn_register to register.
  > RHN Satellite or RHN Classic support will be disabled.

Expected results:

Message about not being registered should be issued on stderr.

Comment 2 RHEL Program Management 2013-01-22 06:48:18 UTC

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

    901612: Yum plugin warnings should go to stderr, not stdout

Comment 6 Bryan Kearney 2013-02-08 17:18:47 UTC

Fixed in the 1.8.2 version of subscription-manager or python-rhsm

Comment 11 Devan Goodwin 2014-01-30 14:04:31 UTC

Apologies but we have to revert this fix due to https://bugzilla.redhat.com/show_bug.cgi?id=1017354 (and others)

This caused more problems than the original behaviour and after discussion, we feel the original behaviour was correct, these are not error messages, they are informational only, and belong on stdout. (not stderr)

Any script parsing yum output would need to be able to handle this and only extract the information it needs, but this is the nature of parsing command output, particularly when the command has a plugin architecture like yum.

Sorry for any complications but we need to revert the fix in the next subscription-manager release.
