Bug 689786

Description of problem:

yum history is obviously using UID to identify the user in the  transaction. It would be better if also the login would be stored. In case the user is deleted and a new one receives the same UID, transtactions performed by the old user are assigned to the new one in the history.
If yum would store also the login, it could compare the login if the current user and inform that the transaction has been done by an already removed user.

I think it is not necessary to store more details about the user, the login is usualy enough to identify the user using other evidence.

Actual results:

1. I have several transactions made by user IlikeMyLongName...

# yum history list
Loaded plugins: refresh-packagekit, rhnplugin
ID     | Login user               | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
   189 | <IlikeMyLongNameSoMuchEv | 2011-03-22 08:37 | Erase          |    1   
   188 | <IlikeMyLongNameSoMuchEv | 2011-03-22 08:36 | Install        |    1   
   187 | <IlikeMyLongNameSoMuchEv | 2011-03-22 08:35 | Erase          |    1   
   186 | <IlikeMyLongNameSoMuchEv | 2011-03-22 08:31 | Install        |    1   

2. Now I delete this user account and add a new acount "myuser" which receives the same uid. I let "myuser" do a new transaction.

# yum history list
Loaded plugins: refresh-packagekit, rhnplugin
ID     | Login user               | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
   190 | Me <myuser>              | 2011-03-22 08:42 | Install        |    1   
   189 | Me <myuser>              | 2011-03-22 08:37 | Erase          |    1   
   188 | Me <myuser>              | 2011-03-22 08:36 | Install        |    1   
   187 | Me <myuser>              | 2011-03-22 08:35 | Erase          |    1   
   186 | Me <myuser>              | 2011-03-22 08:31 | Install        |    1   

old transactions are assigned to the new user


Expected results:

something like

# yum history list
Loaded plugins: refresh-packagekit, rhnplugin
ID     | Login user               | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
   190 | Me <myuser>              | 2011-03-22 08:42 | Install        |    1   
   189 | REMOVED: <IlikeMyLongNam | 2011-03-22 08:37 | Erase          |    1   
   188 | REMOVED: <IlikeMyLongNam | 2011-03-22 08:36 | Install        |    1   
   187 | REMOVED: <IlikeMyLongNam | 2011-03-22 08:35 | Erase          |    1   
   186 | REMOVED: <IlikeMyLongNam | 2011-03-22 08:31 | Install        |    1
