Which should be running before the 'Running transaction'



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

yum-plugin-downloadonly-1.1.30-14.el6.noarch
yum-3.2.29-43.el6_5.noarch
yum-plugin-security-1.1.30-14.el6.noarch
rpm-4.8.0-37.el6.x86_64
rpm-python-4.8.0-37.el6.x86_64
yum-utils-1.1.30-14.el6.noarch
yum-metadata-parser-1.1.2-16.el6.x86_64
rpm-libs-4.8.0-37.el6.x86_64
yum-rhn-plugin-0.9.1-49.el6.noarch
[root@iranzo ~]# 


How reproducible:
- Create a spec file with a %pretrans section doing 'echo'
- Install it using yum


Actual results:
- 'Text' will be displayed after running transaction 

Expected results:
- 'Text' should be displayed before running transaction

Fedora 20 still has this issue, but shows messages at a different point during yum installation (but still not prior to Running transaction)

Comment 3 Panu Matilainen 2013-12-17 11:04:07 UTC 
When %pretrans gets run is not in yum's control, %pretrans is executed by rpm it always occurs in the same spot. The *output* can (and often does) come later because of how yum wraps the logging from rpm.
