version constraints are somewhat not respected and break concretizer #5753
Description
with #5752 slepc will correctly have
depends_on('[email protected]:3.7.7', when='@3.7.1:3.7.4')
so I expected the current stable release of [email protected] to result in [email protected], yet this does not happen:
$ spack spec -I dealii

slepc requires petsc version 3.7:3.7.7, but spec asked for 3.8.0
So it looks like petsc got settled with 3.8.0 before trying to concretize slepc.
Not sure if it's a bug or limitation of the current concretizer.
@tgamblin @scheibelp ping
p.s. a workaround is to add to ~/.spack/packages.yaml:
petsc:
version: [3.7.7]
For completeness, here are my settings:
packages:
all:
compiler: [clang, gcc]
providers:
mpi: [openmpi]
blas: [openblas]
lapack: [openblas]
scalapack: [netlib-scalapack]
cmake:
version: [3.9.0]
suite-sparse:
