Description Florian Festi 2007-06-26 09:20:15 UTC

yum happily installs packages that are conflicting with each other as long as
they are not installed at once.

Version-Release number of selected component (if applicable):
yum-3.2.0-1.fc7

How reproducible:
always

Steps to Reproduce:
yum -y install leafnode
yum -y install suck

or

yum -y install suck
yum -y install leafnode

Actual results:
both packages get installed

Expected results:
Same as when running
yum install suck leafnode

--> Running transaction check
---> Package leafnode.i386 0:1.11.5-4.fc7 set to be updated
---> Package suck.i386 0:4.3.2-14.fc7 set to be updated
--> Processing Conflict: suck conflicts leafnode
--> Finished Dependency Resolution
Error: suck conflicts with leafnode

Comment 1 Seth Vidal 2007-06-26 13:29:01 UTC

I'm pretty sure this was fixed in 3.2.1 which is in updates-testing and rawhide.
please try it and reopen if it is not fixed

Comment 2 Florian Festi 2007-06-26 13:46:03 UTC

Tested CVS HEAD (Tue Jun 26 2007):

yum -y install leafnode
yum -y install suck

now correctly issues an error

yum -y install suck
yum -y install leafnode

still ignores the conflict.

Fixes the conflicts case though we should probably also make leafnode and suck
both have a mutual conflict to each other, not just one of them.

Comment 4 Florian Festi 2007-06-28 13:18:34 UTC

Patch seams to search for the packages name only. AFAIK conflicts match against
provides.

Ther also is another problem with the already existing conflict code that checks
the package's conflicts against the other new packages: This check is only done
once per package. But the conflicts need to be checked against every packages
that is added to the transaction. As their might (and normally will) be added
packages after a resolving loop the conflicts checked in that loop won't be
checked against these packages.

Scenario

Install: A, libA conflicts: libB, B requires: libB
resolveDeps: no conflicts, requires libB
add libB
resolveDeps: everything ok
