To work properly, Spack requires a few directories from its repository to be added to
`sys.path`. Previously these were buried in `spack_installable.main.main()`, but it's
sometimes useful to get the paths separately, e.g., if you want to set up your own
functioning spack environment.
With this change, adding the paths is much simpler:
```python
import spack_installable
sys.path[:0] = get_spack_sys_paths(spack_prefix)
```
- [x] Add `get_spack_sys_paths()` method with extra paths in order.
- [x] Refactor `spack_installable.main.main()` to use it.
With an improper/incomplete/broken installation of Clingo, it can be
importable but not have any of the expected attributes
Improve error reporting in this case
* Restore PackageBase class, and modify only ASP
This prevents a noticeable slowdown in concretization
due to the number of directives involved.
* Fix issue with 'clang' being preferred to 'gcc',
due to runtime version weights
* Constraints on runtimes are declared by compilers
The declaration of available runtime versions, and of
their compatibility constraints are in the associated
compiler class.

The gcc-runtime package adds a separate node for gcc's dynamic runtime
libraries.
This should help with:
1. binary caches where rpaths for compiler support libs cannot be
relocated because the compiler is missing on the target system
2. creating "minimal" container images
The package is versioned like `gcc` (in principle it could be
unversioned, but Spack doesn't always guarantee not mixing compilers)
If you are calling Spack from the python API, you might have written something like this
before #41529:
```
find = SpackCommand("find")
find('--format={name}', 'saxpy@1.0.0', '+rocm', 'amdgpu_target="gfx90a"')
```
But with the breaking change in #41529, you should write:
```
find = SpackCommand("find")
find('--format={name}', 'gromacs', '+rocm', 'amdgpu_target=gfx90a')
```
Note that we don't need quotes in Python strings, and that this is what would come in
via argv if you typed a quoted variant on the CLI.
The error messages for strings like this are not great -- you get something like this:
```
==> No package matches the query: gromacs+rocm amdgpu_target="gfx90a"
```
Which doesn't indicate that the issue might be your quoting. This is because we were
simply outputting the argv we got, instead of using spec.format() to output the error
message. This PR fixes such errors to use `spec.format()` and to look like this:
```
==> No package matches the query: gromacs+rocm amdgpu_target='"gfx90a"'
```
So users should have an easier time understanding that Spack considers the variant value
to contain quotes here.
- [x] update ConstraintAction to store parsed Specs
- [x] refactor commands to display formatted parsed Specs instead of raw input
Users expect that changes to the externals sections in packages.yaml config apply immediately, but reuse concretization caused this not to be the case. With this commit, the concretizer is only allowed to reuse externals previously imported from config if identical config exists.
This PR adds a flag `--tag/-t` to `buildcache push`, which you can use like
```
$ spack mirror add my-oci-registry oci://example.com/hello/world
$ spack -e my_env buildcache push --base-image ubuntu:22.04 --tag my_custom_tag my-oci-registry
```
and lets users ship a full, installed environment as a minimal container image where each image layer is one Spack package, on top of a base image of choice. The image can then be used as
```
$ docker run -it --rm example.com/hello/world:my_custom_tag
```
Apart from environments, users can also pick arbitrary installed spec from their database, for instance:
```
$ spack buildcache push --base-image ubuntu:22.04 --tag some_specs my-oci-registry gcc@12 cmake
$ docker run -it --rm example.com/hello/world:some_specs
```
It has many advantages over `spack containerize`:
1. No external tools required (`docker`, `buildah`, ...)
2. Creates images from locally installed Spack packages (No need to rebuild inside `docker build`, where troubleshooting build failures is notoriously hard)
3. No need for multistage builds (Spack just tarballs existing installations of runtime deps)
4. Reduced storage size / composability: when pushing multiple environments with common specs, container image layers are shared.
5. Automatic build cache: later `spack install` of the env elsewhere speeds up since the containerized environment is a build cache
These packages were written before the "requires" directive,
and so they are conflicting with all compilers but Fujitsu
to express they _require_ `%fj`
* Ensure a spack libproj is used instead of a system libproj when libproj < 8.

* add trim function to `Spec` and `--ignore` option to 'spack diff'
Allows user to compare two specs while ignoring the sub-DAG of a particular dependency, e.g.
spack diff --ignore=mpi --ignore=zlib trilinos/abcdef trilinos/fedcba
to focus on differences closer to the root of the software stack
Sometimes env variables computed in `setup_run_environment` depend on tests
w.r.t. files in `spec.prefix`, but Spack temporarily projects `spec.prefix` to
the view.
This is problematic for two reasons:
1. Some packages iterate over `<prefix>/bin`: they expect only the current
package's executables, but find all linked in the view, leading to false
positives.
2. Some packages test for `os.path.islink(...)`, which is always true in a view
`gcc` is an example that does both.
This PR lets Spack compute the environment modifications using the original
prefix, and projects to the view afterwards
Currently, a virtual spec is composed of just a name and a version. When a virtual spec contains other components, such as variants, Spack won't emit warnings or errors but will silently drop them - which is unexpected by users.
This adds three new versions in the 31.* series. Release notes of 31.0.0 at https://github.com/acts-project/acts/releases/tag/v31.0.0. No changes to the CMakeLists.txt files that need addressing in the package recipe.
The only new feature I'm a bit concerned about is https://github.com/acts-project/acts/pull/2626, which replaces testing for C++20 concepts support by the feature-testing macro `__cpp_concepts`, which is also a C++20 feature. So technically we now should require `cxxstd=20` even though Acts itself still allows (and defaults to) 17. Judging by https://en.cppreference.com/w/cpp/compiler_support/20, the support for feature-testing macros was added very early by most compilers.
