Flux package reworked to include all new dependencies, fixed issues with a
clean-build of hwloc, lua and czmq as well that prevented flux from building
cold on a minimal system.
- _cross_provider_maps() had suffered some bit rot (map returned was
ill-formed but still worked for cases with one vdep)
- ProviderIndex.satisfies() was only checking whether the result map
was non-empty. It should check whether all common vdeps are *in*
the result map, as that indicates there is *some* way to satisfy
*all* of them. We were checking whether there was some way to
satisfy *any one* of them, which is wrong.
- Above would cause a problem when there is more than one vdep provider.
- Added test that covers this case.
- Added `constrained()` method to Spec. Analogous to `normalized()`:
`constrain():constrained() :: normalize():normalized()`
Added test for, e.g.:
import spack.pkg.builtin.mock.mpich
import spack.pkg.builtin.mock.mpich as mpich
from spack.pkg.builtin.mock.mpich import Mpich
Among others. These ensure that direct package imports work so that
packages can be extended.
Package repositories now look like this:
top-level-dir/
repo.yaml
packages/
libelf/
package.py
mpich/
package.py
...
This leaves room at the top level for additional metadata, source,
per-repo configs, indexes, etc., and it makes it easy to see that
something is a spack repo (just look for repo.yaml and packages).
importing nose (which is also in Spack's external/ directory) outputs a warning
(since there is more than one nose package). This avoids printing the warning
to the user.
The setup-env.sh script now saves off the argument array before shifting off
all the arguments so that the final command invocation doesn't arbitrarily
requote the arguments. All external quoting is preserved now. This has been
thoroughly tested with zsh, but should probably be tested with bash etc.
before acceptance.
unit tests, so tracking tests with sets wouldn't work unless I extracted the
details relevant to the particular test. For now a simple count will work so
using a set was unnecessary anyways.
