Description of problem:

Given installed 'package-1.0.0' requiring '1.0.0 <= dependency < 2.0.0' (also
installed)

Attempting to install 'dependency-2.0.0' will not detect that the the installed
package 'package' requires disposition

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

3.2.7 - 3.2.16

How reproducible:

Consistently with new install and no plugins

Steps to Reproduce:

Given installed 'package-1.0.0' requiring 'dependency >= 1.0.0' and 'dependency < 2.0.0' (also 
installed)

Attempting to install 'dependency-2.0.0' will not detect that the the installed package 'package' 
requires disposition.

[root@aa0-001-3-v1 ~]# rpm -qR package
dependency >= 1.0.0
dependency < 2.0.0
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1

[root@aa0-001-3-v1 ~]# rpm -q dependency
dependency-1.0.0-0

[root@aa0-001-3-v1 ~]# yum install -d0 dependency-2.0.0-0.noarch-linux.rpm -y
ERROR with rpm_check_debug vs depsolve:
dependency is needed by (installed) package
dependency is needed by (installed) package


Actual results:

Yum fails to notice that replacing dependency will require removing or updating the installed dependent "package"


Expected results:

Either remove or attempt to find an update for dependents

Additional info:

depsolve.py::_checkRemove() -> transactioninfo.py::getRequires(*prov) to find list of packages 
requiring *prov
                            -> transactioninfo.py::getOldRequires(*prov) 
                            -> rpmsack.py::getRequires(*prov)
                            -> packages.py::matchingPrcos('requires', *prov) for po in requiring packages
                            -> rpmUtils::miscUtils::rangeCompare(*prov, tup) for tup in requirements(self)

Since rangeCompare expects arguments of (reqtup, provtup), and is logically implemented in terms of 
these concepts, the above 
usage is conceptually reversed and invalid.
