* Allow branching out of the "generic build" unification set
For cases like the one in https://github.com/spack/spack/pull/39661
we need to relax rules on unification sets.
The issue is that, right now, nodes in the "generic build" unification
set are unified together with their build dependencies. This was done
out of caution to avoid the risk of circular dependencies, which would
ultimately cause a very slow solve.
For build-tools like Cython, however, the build dependencies is masked
by a long chain of "build, run" dependencies that belong in the
"generic build" unification space.
To allow splitting on cases like this, we relax the rule disallowing
branching out of the "generic build" unification set.
* Fix issue with pure build virtual dependencies
Pure build virtual dependencies were not accounted properly in the
list of possible virtuals. This caused some facts connecting virtuals
to the corresponding providers to not be emitted, and in the end
lead to unsat problems.
* Fixed a few issues in packages
py-gevent: restore dependency on py-cython@3
jsoncpp: fix typo in build dependency
ecp-data-vis-sdk: update spack.yaml and cmake recipe
py-statsmodels: add v0.13.5
* Make dependency on "blt" of type "build"
The "concretizer" section has been extended with a "duplicates:strategy"
attribute, that can take three values:
- "none": only 1 node per package
- "minimal": allow multiple nodes opf specific packages
- "full": allow full duplication for a build tool
This adds a new mode for `concretizer:reuse` called `dependencies`,
which only reuses dependencies. Currently, `spack install foo` will
reuse older versions of `foo`, which might be surprising to users.
`spack env create` enables a view by default (in a weird hidden
directory, but well...). This is asking for trouble with the other
default of `concretizer:unify:false`, since having different flavors of
the same spec in an environment, leads to collision errors when
generating the view.
A change of defaults would improve user experience:
However, `unify:true` makes most sense, since any time the issue is
brought up in Slack, the user changes the concretization config, since
it wasn't the intention to have different flavors of the same spec, and
install times are decreased.
Further we improve the docs and drop the duplicate root spec limitation
* Introduce concretizer:unify option to replace spack:concretization
* Deprecate concretization
* Make spack:concretization overrule concretize:unify for now
* Add environment update logic to move from spack:concretization to spack:concretizer:reuse
* Migrate spack:concretization to spack:concretize:unify in all locations
* For new environments make concretizer:unify explicit, so that defaults can be changed in 0.19
* ASP-based solver: allow configuring target selection
This commit adds a new "concretizer:targets" configuration
section, and two options under it.
- "concretizer:targets:granularity" allows switching from
considering only generic targets to consider all possible
microarchitectures.
- "concretizer:targets:host_compatible" instead controls
whether we can concretize for microarchitectures that
are incompatible with the current host.
* Add documentation
* Add unit-tests
The concretizer is going to grow to have many more configuration,
and we really need some structured config for that.
* We have the `config:concretizer` option that chooses the solver,
but extending that is awkward (we'd need to replace a string with
a `dict`) and the solver choice will be deprecated eventually.
* We have the `concretization` option in environments, but it's
not a top-level config section -- it's just for environments,
and it also only admits a string right now.
To avoid overlapping with either of these and to allow the most
extensibility in the future, this adds a new `concretizer` config
section that can be used in and outside of environments. There
is only one option right now: `reuse`. This can expand to include
other options later.
Likely, we will soon deprecate `config:concretizer` and warn when
the user doesn't use `clingo`, and we will eventually (sometime later)
move the `together` / `separately` options from `concretization` into
the top-level `concretizer` section.
This commit just adds the new section and schema. Fully wiring it
up is TBD.
