Currently, environments can end up with higher priority than `-C` custom
config scopes and `-c` command line arguments sometimes. This shouldn't
happen -- those explicit CLI scopes should override active environments.
Up to now configuration behaved like a stack, where scopes could be only be
pushed at the top. This PR allows to assign priorities to scopes, and ensures
that scopes of lower priorities are always "below" scopes of higher priorities.
When scopes have the same priority, what matters is the insertion order.
Modifications:
- [x] Add a mapping that iterates over keys according to priorities set when
adding the key/value pair
- [x] Use that mapping to allow assigning priorities to configuration scopes
- [x] Assign different priorities for different kind of scopes, to fix a bug, and
add a regression test
- [x] Simplify `Configuration` constructor
- [x] Remove `Configuration.pop_scope`
- [x] Remove `unify:false` from custom `-C` scope in pipelines
On the last modification: on `develop`, pipelines are relying on the environment
being able to override `-C` scopes, which is a bug. After this fix, we need to be
explicit about the unification strategy in each stack, and remove the blanket
`unify:false` from the highest priority scope

Currently, we have `config:shared_linking:missing_library_policy` to error
or warn when shared libraries cannot be resolved upon install.
The new `spack verify libraries` command allows users to run this post
install hook at any point in time to check whether their current
installations can resolve shared libs in rpaths.
* Reproducer should decude artifact root from concrete environment
* Add documentation on the layout of the artifacts directory
* Use dag hash in the container name
* Add reproducer options to improve local testing
* --use-local-head allows running reproducer with
the current Spack HEAD commit rather than computing
a commit for the reproducer
* Add test to verify commits and recreating reproduction environment
* Add test for non-merge commit case
* ci reproduce-build: Drop overwrite option
in favor of throwing an error if the working dir is non-empty
Currently, when we setup the ASP problem for `clingo`, we don't take into account the configuration. This results in setting up ASP problems that are larger than necessary, with possibly redundant information, and higher concretization times.
This PR tries to improve things by adding an opt-in feature that computes the _possible dependencies_ of a solve taking also into account the current configuration, and avoids adding possible dependencies that we are certain can't be in the final solution.
The feature can be activated with:
```yaml
concretizer:
static_analysis: true
```
Examples of simple rules to discard dependencies are:
- Dependencies that are not buildable, and for which no binary is present (e.g. `cray-mpich` etc. on non Cray systems)
- Dependencies that are not for the current platform (e.g. `msmpi` on non Windows platforms)
- Conditional dependencies that cannot be activated, because of some user requirement (e.g. `cuda` etc. if the user requires `~cuda` in configuration)
- Virtual providers that cannot be used, because of a requirement on a virtual
The speed-up these rules seem to give depends on the use case at hand, but if the configuration is updated properly, they are noticeable.
Since in cases where there is no rule to exclude packages upfront, reuse is active, and this option is activated, it's possible to see some minor slow down, the feature has been added as opt-in, so it's turned off by default.
This adds a new configuration section called `env_vars:` that can be set in an environment.
It looks very similar to the existing `environment:` section that can be added to `modules.yaml`,
but it is global for an entire spack environment. It's called `env_vars:` to deconflate it with spack
environments (the term was too overloaded).
The syntax looks like this:
```yaml
spack:
specs:
- cmake%gcc
env_vars:
set:
ENVAR_SET_IN_ENV_LOAD: "True"
```
Any of our standard environment modifications can be added to the `env_vars` section, e.g.
`prepend_path:`, `unset:`, `append_path:`, etc. Operations in `env_vars:` are performed
on `spack env activate` and undone on `spack env deactivate`.
* e4s cray rhel ci stack: re-enable and update for new cpe, should fix cray libsci issue
* only run e4s-cray-rhel stack
* Mkae Autotools build_system point at correct build_directory
* remove selective enable of cray-rhel stacks
* restore SPACK_CI_DISABLE_STACKS
* use dot prefix to hide cray-sles jobs instead of comment-out

A few changes to tarball creation (for build caches):
- do not run file to distinguish binary from text
- file is slow, even when running it in a batched fashion -- it usually reads all bytes and has slow logic to categorize specific types
- we don't need a highly detailed file categorization; a crude categorization of elf, mach-o, text suffices.
detecting elf and mach-o is straightforward and cheap
- detecting utf-8 (and with that ascii) is highly accurate: false positive rate decays exponentially as file size increases. Further it's not only the most common encoding, but the most common file type in package prefixes.
iso-8859-1 is cheaply (but heuristically) detected too, and sufficiently accurate after binaries and utf-8 files are classified earlier
- remove file as a dependency of Spack in general, which makes Spack itself easier to install
- detect file type and need to relocate as part of creating the tarball, which is more cache friendly and thus faster
`kcov` was removed in Ubuntu 24.04, and it is no longer
installable via `apt` in our CI images. Instal it via
Linuxbrew instead, at least until it comes back to Ubuntu.
`subversion` is also not installed on ubuntu 24 by default,
so we have to install it manually.
- [x] Add linuxbrew to linux tests
- [x] Install `kcov` with brew
- [x] Install subversion with `apt`

There are still more fix ups required for the missing libs to work as
expected in CI. Dropping the error requirement in favor of moving to a
log scraping method until we can verify all package issues have been
addressed correctly.
* Set the "build_jobs" on concretization/generate for CI
build_jobs also controls the concretization pool size. Set this
in the config section for CI generate.
This config is overwritten by build_job CI using the SPACK_BUILD_JOBS
environment variable. This implicitly will drop the default build
CPU request on all "default" grouped build jobs from (max) 16 to 8.
* Add default allocations for build jobs
* Add common jobs and concretize args to ci generate and rebuild
* CI: Specify parallel concretize and build jobs via argument
* Increase power and cray concretization limits
Lowering limits for these stacks creates timeout
* Increase default pool size to 8
intermittent timeouts with 4 CPU
* Add reduced requests for windows for now
This commit adds a config option `config:shared_linking:missing_library_policy:error/warn/ignore` which will cause installation errors or warnings when ELF executables or libraries need shared libraries which cannot be resolved from RPATH search paths. The default is to ignore.
This is a safeguard against accidentally linking to system libraries instead of Spack libraries. It makes it more likely that build cache installs work on different machines. It works only at the level of libraries, not at the level of symbols. Some system dependencies are allowed (e.g. kernel and libc).
Packages can (but are discouraged to) set `unresolved_libraries` to a list of patterns of sonames/library names that are know to be unresolvable in RPATHs. In the future this could be made more fine-grained in a non-breaking way by allowing a dictionary of patterns `lib => [deps]`.
