Ensures all tags are ready before checkout, using `--branch` if possible and
an extra pull if that is not available. Also adds `--depth 1` to create
shallow clones if the git version is sufficient.
Fixes#64.
It is currently less painful to pull the source from github, compile it into a
gem, then install the gem, than it is to download a gem and install it. This
still lacks an activation mechanism, but `spack use tmuxinator` is functional.
- This can result in the user being prompted to download an unsafe
version.
- Avoids overly strict errors when something *could* be satisfiable
but we don't know about hte version.
- The following now work differently:
spec['mpi']
spec['blas']
This can return a spec for openmpi, mpich, mvapich, etc., EVEN if
the spec is already concretized. This means that in a package that
`depends_on('mpi')`, you can do `spec['mpi']` to see what it was
concretized to. This should simplify MPI and BLAS packages.
'mpi' in spec
'blas' in spec
Previously, if the spec had been concretized, these would be `False`
because there was not a dependency in the DAG with either of these
names. These will now be `True` even if the spec has been
concretized. So, e.g., this will print "YES"
s = Spec('callpath ^mpich')
if 'mpi' in spec:
print "YES"
- Similarly, this will be True:
Spec('mpich').satisfies('mpi')
- Because of the way virtual dependencies are currently implemented,
the above required some fiddling around with `package.py` so that it
would never call `Spec.__contains__` (and result in endless
recursion).
- This should be fixed by allowing virutal dependnecies to have their
own package class.
- This would allow a quicker check for vdeps, without a call to
`all_packages`.
- For the time being, `package.py` shouldn't call `__contains__`
