Description Michal Domonkos 2018-02-28 13:08:06 UTC

Description of problem:
Setting "update_messages=no" has no effect.  The messages will be emitted regardless.

The reason is that we only respect the update_messages value in a few places before emit*() calls but not in others.

We should fix this behavior according to the update_messages description that says:
# Whether a message should be emitted when updates are available,
# were downloaded, or applied.

One way would be to check for the value in the respective emit*() methods themselves (probably not all, just those related to downloading/updating) to make sure we catch all such occurrences.

Version-Release number of selected component (if applicable):
yum-3.4.3-154.el7.noarch

How reproducible:
100%

Steps to Reproduce:
1. Make sure /etc/yum/yum-cron.conf contains the following:
  update_messages=no
  emit_via=stdio
  random_wait=0
3. Make sure there are updates available in the enabled repos
4. Run "yum-cron /etc/yum/yum-cron.conf"

Actual results:
The transaction is dumped to stdout, along with some informational messages.

Expected results:
No non-error messages should be printed.
