Description Dave Jones 2008-07-10 17:10:28 UTC

during a yum update, I saw..

 Updating       : nfs-utils                                     [ 66/212] 
Error unpacking rpm package 1:nfs-utils-1.1.2-12.fc10.i386

and then later..
Stopping RPC idmapd: [  OK  ]
Starting RPC idmapd: [  OK  ]
Stopping NFS locking: [  OK  ]
Stopping NFS statd: [  OK  ]
Starting NFS statd: [  OK  ]
  Cleanup        : nfs-utils                                     [171/212] 

and the result is..

$ rpm -q nfs-utils
package nfs-utils is not installed


if the install stage breaks for whatever reason, we really shouldn't be running
the cleanup stage.  I'm just really thankful this happened to a bunch of
non-critical packages. if it was glibc, I'd be completely hosed.

The problem is harder to fix than what is implemented in rpm-4.4.2.3.4.5.6.7...

In general, package side effects, like Obsoletes: and/or upgrade,
are dependent on the success of the install. In your case, the
nfs-install package, which has a single dependent action, removing
the old nfs-utils package.

The general form of relations with the side effects of Obsoletes: and upgrades is many <-> many.
Consider what should happen if the nfs-utils package carried several Obsoletes: as
well as the implicit upgrade. Should the Obsoletes: be performed if the install fails?
I think not.

The many-to-many side effects dependent on the success (or failure) of
the initial install (in yr case nfs-utils) is correctly handled in the @rpm5.org
code base for several years now.

Have fun!

Fixed in rawhide now.
