Description Pavel Roskin 2004-05-21 16:33:06 UTC

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6)

Description of problem:
When I run "yum upgrade" on a clean default workstation install of
Fedora Core 2, it wants to download compat-db-4.1.25-2.1.i386 (and
also compat-libstdc++-7.3-2.96.126.i386 as dependency).
Running "yum -d 10 upgrade" shows following lines:

versioned obsolete
db4, 2, 0, 4.2, None
None, None, None vs 0, 4.2, None = -1
compat-db obsoleting db4
versioned obsolete
db4-devel, 2, 0, 4.2, None
None, None, None vs 0, 4.2, None = -1
compat-db obsoleting db4-devel
versioned obsolete
db4-utils, 2, 0, 4.2, None
None, None, None vs 0, 4.2, None = -1
compat-db obsoleting db4-utils
[snip]
nulist = 904
uplist = 0
newlist = 904
obsoleting = 1
obsoleted = 3
userlist entry *
db4-utils matched in oulist
db4-utils obsoleted by compat-db
db4 matched in oulist
db4 obsoleted by compat-db
db4-devel matched in oulist
db4-devel obsoleted by compat-db

compat-db only obsoletes versions of db4 prior to 4.2.  From the spec
file of compat-db:

Obsoletes: db2, db2-devel, db2-utils
Obsoletes: db3, db3-devel, db3-utils
Obsoletes: db31, db32, db3x
Obsoletes: db4 < 4.2, db4-devel < 4.2, db4-utils < 4.2

I have db4-4.2.52-3.1 installed.  It should not be obsoleted by
compat-db.  In fact, running "rpm -U compat-db-4.1.25-2.1.i386.rpm"
(provived that compat-libstdc++-7.3-2.96.126 is installed) succeeds
without an attempt to uninstall db4.


Version-Release number of selected component (if applicable):
yum-2.0.7-1.1

How reproducible:
Always

Steps to Reproduce:
1. Run "yum upgrade"


Actual Results:  yum suggests installing compat-db


Expected Results:  yum should not suggest installing compat-db

Additional info:

Clean Fedora Core 2 install as Workstation, all defaults.

This patch fixes the problem

yum requests the version for the package being installed, but it should be
using the name of the candidate for obsoleting.  In my case, compat-db
obsoletes db4 4.2 and older.  4.2 is compared to the version of compad-db
rather than db4.  Also, rpmNevral.evr() doesn't work for packages that are not
installed yet.

Patch looks plausible, handed off to skvidal.

Please reopen if the bug is not fixed in next release of yum
into fc3.

nice catch. I've applied it to cvs. It'll come out in yum 2.0.8

Thanks
