The test introduced herein illustrates a behavior that may be unexpected
to package writers.
It creates a package "pkg3" that is configured to depend on a
"dependency" which version is between 3 and 4, inclusive. Two other
packages are already present, providing "dependency" in version 2 and 5,
respectively. So, the situation looks roughly like this:
pkg1 pkg3 pkg2
provides depends on provides
| <------------> |
version __________2____________3____________4____________5___________...
This seems to be enough to satisfy pacman when installing "pkg3". From
an iterative standpoint, this is completely logical: First, the
requirement "dependency>=3" is checked. There is a package that
satisfies this restriction, it is called "pkg2". Afterwards,
"dependency<=4" is covered in the same way by "pkg1".
Nonetheless, what a package writer intends when specifying
depends=('dependency>=3' 'dependency<=4')
is most probably that pacman should only allow this package to be
installed when there indeed is a package present that provides a version
of "dependency" that lies _between_ 3 and 5.
