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.
`relocate_links` warns when the target is absolute and not matched by
any prefix from the prefix to prefix map.
This can lead to false positives, cause the prefix to prefix map does
not contain trivial/identity entries whenever a package is installed to
its original location.
Since relocate_links is the odd one out there (we don't warn about
similar issues with rpaths, etc), just remove the warning.
* Remove variable from cmake.py
#48775 left a dangling variable that was not caught in CI but by the eyes of @haampie. Restructure variable to local method.

Add ruff configuration to `pyproject.toml`.
This allows `ruff format` in the Spack repository to format all the files we care about,
with our line length of 99, the exceptions we already put in place, and excluding things
we don't auto-format, like vendored dependencies.
Right now it'll reformat 175 or so files, but only slightly, in places where `ruff` differs from
`black`. For the most part I like the ruff format decisions better than `black`, but none of
the changes seem too severe.
This does not change `spack style` -- I figure that can come later but this at least will
let people start playing with `ruff`.

These are some changes that `ruff check --fix` would make that the current
`spack style` also agrees with. Make the changes now so that the `ruff`
change is less disruptive.

Currently, environments created from manifest files with relative includes result in broken
references to config files.
This PR modifies `spack env create` to create local copies in the new environment of any local
config files from relative paths in the environment manifest passed as an init file.
This PR does not change the behavior if the include is an absolute path or if the include is from
a relative path outside the environment directory, but it does warn about missing relative includes if
they are inside the environment directory.
Includes regression test and short blurb in docs.
* package api: drop wildcard re-export
To ensure package repos are forward/backward compatibility with Spack,
we should explicitly export all symbols we want to expose in the public
package API, and drop `from spack.something import *` because
removal/addition to the public API will go unnoticed.
Also `llnl.util.filesystem` has some methods that shouldn't be exposed
in the package API, so better to enumerate a subset explicitly.
* remove flatten_dependencies / install_dependency_symlinks
Regressed in #47126
Spack was not interpreting mirrors using relative path with respect to the
metadata directory.

* test_no_matching_compiler_specs: does not need mock_low_high_config,
since mutable_config is already used at class level
* bindist.py: setup a configuration that doesn't super-impose builtin.mock
over builtin
* builder.py: use a mock configuration for the tests
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`.
* Reduce the size of outputted go built binaries
* Remove unused import from go package
* go: remove comment from setup dependents build env
* Add back missing imports after rebase
* Backward compat with Python 3.9 for socket.timeout
* Forward compat with Python [unknown] as HTTPResponse.geturl is deprecated
* Catch timeout etc from .read()
* Some minor simplifications: json.load(...) takes file object in binary mode.
* Fix CDash code which does error handling wrong: non-2XX responses raise.
Should be sufficient to set CONFIG_SITE to /dev/null before running configure to
prevent any config site file to be loaded, which currently causes non-determinism in builds.
Setting the variable CONFIG_SITE prevents configure files to check $prefix/share/config.site,
$prefix/etc/config.site, $ac_default_prefix/share/config.site, $ac_default_prefix/etc/config.site
so we don't have to patch a block of code.
* Address quoting issue that casuses dev_paths containing @ symbols to parse as versions
* Fix additional location were dev_path was imporperly constructed
The dev_path must be quoted to avoid parsing issues when
paths contain '@' symbols. Also add tests to catch
regression of this behavior
* Format to fix line length
* fix failing tests
* Fix whitespace error
* Add binary_compatibility fixture to test
* Change string formatting to avoid multiline f string
* Update lib/spack/spack/test/concretization/core.py
* Add tmate debug session
* Revert "Add tmate debug session"
This reverts commit 24e2f77e3c.
* Move test and refactor to use env methods
* Update lib/spack/spack/test/cmd/develop.py
