* Add missing MultiMethodMeta metaclass in builders
and remove the Python 2 fallback option in favor of hard errors to catch
similar issues going forward.
The fallback option can cause about 10K stat calls due to use of
`realpath` in the inspect module, depending on how deep Spack itself is
nested in the file system, which is ... undesirable.
* code shuffling to avoid circular import
* more reshuffling
* move reserved variant names into variants module
* Adds an MSBuild system + Builder to the icu4c package
* Adds custom install method as MSBuild system does not vendor an
install target
* The cxxstd variant is not supported on Windows (there are no config
options you use to tell the build system what cxx standard to
build against), so the variant definition was updated to occur
everywhere except Windows
Also, this commit defines the c/cxx..._flag properties of the MSVC
compiler (although they are not used by `icu4c` and not strictly
necessary to bundle with this PR).
Paths over 260 characters in length are not handled by `shutil.rmtree`
unless they use the extended-length path syntax (using a prefix of
"\\?\").
This fixes an issue where stage cleaning fails when paths in a stage
exceed the normal 260-character limit.
This indicates that other parts of the codebase should be examined/
refactored to handle long paths.
Previously `spack buildcache push --only=package` errored in the OCI
case, but it's been requested that OCI can be used as pure storage w/o
the need for runnable container images.
This commit makes it so that
1. manifests refer only to runtime dependencies that were selected to be
pushed
2. failure to upload a blob among the selected specs does not prevent a
manifest/tag to be created for dependents: they just don't refer to
the missing blob as a layer/dependency
This fixes the following issues:
1. dependents of non-redistributable specs can now be pushed to oci
build caches without error
2. failure to upload one tarball does not cause cascading failures for
dependents whose tarballs do upload succesfully -- so it's better
best-effort behavior
3. for some people uploading with deps caused a massive amount of
fetches of their manifests (which certain registries count as a
download of an image, even though their layers are not fetched) --
being able to specify --only=package reduces the number of fetches.
Stage objects create mirrors ad-hoc from current config.
- There is no way to prevent mirrors from being used
- There is no way to restrict mirrors to source/binary, which is of
course context dependent.
- Stage is also used in build caches, where iterating over mirrors is
already implemented differently, and wouldn't work anyways cause it's
source only, and in particular it makes no sense for OCI build caches.
This commit:
1. Injects the sensible mirrors into the stage object from contexts
where it is relevant
2. Separates mirrors from cache, so that w/o mirrors download cache can
still be used
The test_foreground_background unit test has been marked
xfail for a while, meaning:
- Nobody looks at the results of the test
- It still runs every time
That test happens to hang frequently on some Apple M1 I have access to,
so here I mark it as skip.
Also went through other xfailing and skipped tests, and applied minor changes.

* Add options for sparse checkout in GitFetcher
Newer versions of git have a beta feature called sparse checkout
that allow users to check out a portion of a large repo.
This feature will be ideal for monolithic repo projects that want to
model their infrastructure via spack. This PR implements an addition
to the GitFetcher that allows users to add a `git_sparse_paths`
attribute to package classes or versions which will then use sparse
checkout on those directories/files for the package.

When sending Repo and RepoPath over to a child process,
we go through a marshaling procedure with pickle. The
default behavior for these classes is highly inefficient,
as it serializes a lot of specs that can just be
reconstructed on the other end of the pipe.
Here we write optimized procedures to __reduce__ both
classes.
Extracted from #45638
When adding the "detectable" tag to a package class that has the
"tag" attribute inherited from a base class, we need to copy it to
avoid modifying the base class.
"spack buildcache push" for partially installed environments pushes all it
can by default, and only dumps errors towards the end.
If --fail-fast is provided, error out before pushing anything if any
of the packages is uninstalled
oci build caches using parallel push now use futures to ensure pushing
goes in best-effort style.
The old concretizer is still used to bootstrap clingo from source. If we switch to a DAG model
where compilers are treated as nodes, we need to either:
1. fix the old concretizer to support this (which is a lot of work and possibly research), or
2. bootstrap `clingo` without the old concretizer.
This PR takes the second approach and gets rid of the old concretizer code. To bootstrap
`clingo`, we store some concrete spec prototypes as JSON, select one according to the
coarse-grained system architecture, and tweak them according to the current host.
The old concretizer and related dead code are removed. In particular, this removes
`Spec.normalize()` and related methods, which were used in many unit-tests to set
up the test context. The tests have been updated not to use `normalize()`.

Fixes#43494
Add a set of environment variables SPACK_ALWAYS_CFLAGS (etc.) that
are always applied by the compiler wrapper.
Unlike SPACK_CFLAGS, for example, these will also be applied to
version checks (both SPACK_CFLAGS and SPACK_ALWAYS_CFLAGS will be
applied to the other invocation modes like ccld etc.).
Using this new functionality, the classic Intel and oneAPI compilers
are updated to pass compiler flags that disable warning messages
when newer versions are invoked via their older binary names
(these warnings were also generated for version checks, hence the
need for a new wrapper variable).

For example: spack install py-pyqt5 or py-pyqt6 would install pylupdate5 pyrcc5 and
pyuic5 into in python-venv's install prefix.
Fix https://github.com/spack/spack/issues/45359
* Allow spec queries by `namespace`
Spack specs have "namespaces" that indicate what package repository they come from, but
there has not been a way to use the spec syntax to match one.
You can say things like this:
```console
spack find builtin.zlib
spack find myrepo.zlib
```
But, because namespaces are written as a dot-separated prefix on the name, you can't say
"find me all specs in namespace myrepo". The syntax doesn't allow it.
This PR allows you to specify anonymous specs with namespaces on the CLI. Specifically
you can do queries like this:
```console
spack find namespace=builtin
spack find namespace=myrepo
```
You can use this anywhere else you use spec syntax, e.g. in a config file to separate
installations based on what repo they came from:
```yaml
spack:
config:
install_tree:
root: $spack/opt/spack
projections:
namespace=myrepo: "myrepo_special_path/{name}-{hash}"
namespace=builtin: "builtin/{name}-{hash}"
```
This PR adds a special `namespace_if_anonymous` attribute to specs, which returns the
`namespace` if the spec has no name, otherwise it returns `None`. This allows us to
print the namespace for anonymous specs but to continue hiding it for most views, as
we've done so far.
This is implemented as a special case, but it's one that already exists, along with
`platform`, `os`, `target`, etc. This also reserves existing special case names for
variants so that users cannot define them in their package files. This change is
potentially breaking, but I do not think it will be common. There are no builtin
packages with a variant called `namespace`, and defining `os`, `target`, or `platform`
as a variant would've likely caused other problems if they were already being used.

* format: allow spaces in format specifiers
Key-value pair format specifiers can now contain spaces in the key. This allows us to
add spaces to format strings that are *only* present when the attribute formatted is not
``None``. Instead of writing:
```
{arch=architecture}
```
and special casing `arch=` like a sigil in `Spec.format()`, we can now write:
```
{ arch=architecture}
```
And the space is *only* printed when `architecture` is not `None`. This allows us to
remove the special case in `Spec.format()` for `arch=`.
Previously the only `key=` prefix allowed in format specifiers was `arch=`, but this PR
removes that requirement, and the `key=` part of a key-value specifier can be any name.
It does *not* have to correspond to the formatted attribute.
- [x] modify `SPEC_FORMAT_RE` to allow arbitrary keys in key-value pairs.
- [x] remove special case for `arch=` from `Spec.format()`.
- [x] modify format strings using `{arch=architecture}` to use `{ arch=architecture}`
- [x] add more tests for formatting
This PR saves other more complex attributes like compiler flags and their spacing for later.

The `Executable` class emits a warning when you pass quoted arguments to it:
```

The following arguments may cause problems when executed:
"namespace"
Quotes aren't needed because spack doesn't use a shell. Consider removing them.

This is to warn new package authors who aren't used to calling build commands in python.
It's not useful for `spack pkg grep`, where we really are passing args on the command

The "use_store" context manager is used to swap the value
of a global variable (spack.store.STORE), while keeping
another global variable consistent (spack.config.CONFIG).
When doing that it tries to evaluate the previous value
of the store, if that was not done already. This is wrong,
since the configuration might be in an "intermediate" state
that was never meant to trigger side effects.
Remove that operation, and add a unit test to
prevent regressions.
Since the the MetaPathFinder now owns a lazily constructed RepoPath object, we need to deserialize environments before the package that needs to be restored. Before we were relying on globals to be inconsistent in a way that let the entire process go.

If an external happens to be a provider of anything, the solver would
set its weight to 0, meaning that it is most preferred, even if
packages.yaml config disagrees.
That was done so that `spack external find mpich` would be sufficent to
pick it up as mpi provider.
That may have made sense for mpi specifically, but doesn't make sense
for other virtuals. For example `glibc` provides iconv, and is an
external by design, but it's better to use libiconv as a separate
package as a provider.
Therefore, drop this rule, and instead let users add config:
```
mpi:
require: [mpich]
```
or
```
mpi:
buildable: false
```
which is well-documented.
This change makes `spack external find --not-buildable` mark virtuals
provided by detected packages as non-buildable, so that it's sufficient
for users to let spack detect say mpich and have the concretizer pick it
up as mpi provider even when openmpi is "more preferred".
in case of inheritance the static tags prop may be updated multiple
times, and it turns out builder classes magically inherit from
traditional package classes
While trying to build packages with the OneAPI compiler version 2024.1 I
ran into the following error, indicating that the compiler is unable to
find some necessary libraries:
```
/storage/Software/oneapi/2024.1/compiler/2024.1/bin/sycl-post-link: error
while loading shared libraries: libonnxruntime.1.12.22.721.so: cannot open
shared object file: No such file or directory
icpx: error: unable to execute command: No such file or directory
icpx: error: sycl-post-link command failed due to signal (use -v to see
invocation)
```
Indeed, `libonnxruntime.1.12.22.721.so` does come bundled with the
OneAPI compiler, but it is not available in the build environment by
default. In this commit, I update the custom environment created by
OneAPI to include the `lib/` directory in which these libraries reside
in the `LD_LIBRARY_PATH` environment variable.
Originally if you had `x -> y -> z`, and an env with `x` in its speclist that is concretized but not installed, then `spack find -c y` would not show anything. This was intended: `spack find` has up-until-now only ever listed out installed specs (and `-c` was for adding a preamble section about roots).
This changes `spack find` so:
* `-c` makes it search through all concretized specs in the env (in a sense it is anticipated that a concretized environment would serve as a "speculative" DB and users may want to query it like they query the DB outside of envs)
* Adds a `-i/--install-status` option, equivalent to `-I` from `spack spec`
* Shows install status for either `-c` or `-i`
* As a side effect to prior point, `spack find -i` can now distinguish different installation states (upstream/external)

```

Fix a bug where Spec.tree with cover=nodes reduces deptypes from all
in-edges, including from nodes not reachable from the root, which almost
always happens for concrete specs
`Spec.__getitem__` queries dependent edges, which almost always point to
nodes outside the sub-dag considered. It should only ever look at edges
being traversed.
This modifies heuristic to decay to clingo default
over time. The hope is that this helps with specs
that have an optimal solution with a high penalty.
Let target and compiler heuristic decay too, do not

This adds spack.util.spack_yaml.anchorify, which takes a non-cyclic
dict/list structure, and replaces identical values with (back)
references to the first instance, so that yaml serialization will use
anchors.
`repr` is used to identify sub-dags, which in principle is quadratic
complexity in depth of the graph, but in practice the depth is O(1) so
this should not matter.
Then this is used in CI to reduce the size of generated YAML files to
30% of their original size.
In practice people don't care about having their build dependencies reinstalled with say cflags=-O3 if that is what is set at the input spec, so restrict propagation to link/run deps only.
Also simplify the encoding in asp.
Fix the following on Windows:
* `spack load --list` (this printed 0 packages even if packages were
loaded)
* `spack unload <package>` (this said that the package is not loaded
even if it was)
Update unit tests for `spack load` to also run on Windows (specifically
for ".bat"). This involved refactoring a few tests to parameterize
based on whether the unit tests are being run on a Windows system
(and to account for batch syntax).
When we changed how to deal with errors in November,
we didn't realize that for an unconstrained choice
rule it is more important in the heuristic to guess
what is NOT in the answer set, since it will be the
majority of options.
Previously this was following automatically from what
was in the answer set, via `1 { ... } 1` cardinality
constraints.
Here we improve the heuristic and the solve time for specs.

* Preserve higher weight for CLI git ref versions
Currently the concretizer fails if you reuse a git ref version
that has already been installed but modify the spec at all.
See #38484 for futher diagnosis
The issue here is that since there is no established provenance for
these versions the highest weight they are currently assigned is
that of prior install. Re-use checks then fail because the weight of
the version is identical to the solver.
Ironically, these versions are given the highest weights possible when
specified on the CLI for the first time. They should only appear in a
DAG if they are an exact match or if the user specifies them at the CLI.
Therefore it makes sense to preserve their higher ordering.
Getting this right is critical to moving all branch based versions to a pinned
git-ref in the future.

#40773 introduced python-venv, which improved build isolation and avoids issues with,
e.g., `ubuntu`'s system python modifying `sysconfig` to include a (very unwanted)
`local` directory within the default install layout.
This addresses a few cases where #40773 removed functionality, without harming the
default cases where we use `python-venv`.
Traditionally, *every* view with `python` in it was essentially a virtual environment,
because we would copy the `python` interpreter and `os.py` into every view when linking.
We now rely on `python-venv` to do that, but only when it's used (i.e. new builds) and
only for packages that have an `extends("python")` directive.
This again makes every view with `python` in it a virtual environment, but only
if we're not already using a package like `python-venv`. This uses a different
mechanism from before -- instead of using the `virtualenv` trick of copying `python`
into the prefix, we instead create a `pyvenv.cfg` like `venv` (the more modern way
to do it).
This fixes two things:
1. If you already had an environment before Spack `v0.22` that worked, it would
stop working without a reconcretize and rebuild in `v0.22`, because we no longer
copy the python interpreter on link. Adding `pyvenv.cfg` fixes this in a more
modern way, so old views will keep working.
2. If you have an env that only includes python packages that use `depends_on("python")`
instead of `extends("python")`, those packages will now be importable as before,
though they won't have the same level of build isolation you'd get with `extends`
and `python-venv`.
* views: avoid making client code deal with link functions
Users of views and ViewDescriptors shouldn't have to deal with link functions -- they
should just say what type of linking they want.
- [x] views take a link_type, not a link function
- [x] views work out the link function from the link type
- [x] view descriptors and commands now just tell the view what they want.

In #30882, we made Spack ignore `-Werror` calls so that it could more easily build
projects that inject `-Werror` into their builds. We did this by translating them to
`-Wno-error` in the compiler wrapper. However, some compilers (like `nvhpc`) do not
support `-Wno-error`. We need to exclude them from this feature until they do.
- [x] make a property on `PackageBase` for `keep_werror` that knows not to use it for
`nvhpc`.
- [x] update property so that it keeps only the specific `-Werror=...` args for newer nvhpc's,
which support `-Wno-error` but not `-Wno-error=...`

When Spack concretizes environments, it prints every (newly concretized) root spec
individually with all of its dependencies. For most reasonably sized environments, this
is too much output. This is true for three commands:
* `spack concretize` when concretizing an environment with newly added specs
* `spack install` when installing an environment with newly added specs
* `spack spec` with no arguments in an environment
The output dates back to before we had unified environments or nicer spec traversal
routines, and we can improve it.
This PR makes environment concretization output analogous to what we do for regular
specs. Just like `spack spec` for a single spec, we show all root specs with no
indentation, so you can easily see the specs you explicitly requested. Dependencies are
shown:
1. With indentation according to their depth in a breadth-first traversal starting at
the roots;
2. Only once if they appear on paths from multiple roots
So, the default is now consistent with `spack spec` for one spec--it's `--cover=nodes`.
i.e., if there are 100 specs in your environment, you'll get 100 lines of output.
If you want to see more details, you can do that with `spack spec` using the arguments
you're already familiar with. For example, if you wanted to see dependency types and
*all* dependencies, you could use `spack spec -l --cover=edges`. Or you could add
deptypes and namespaces with, e.g. `spack spec -ltN`.
With no arguments in an environment, `spack spec` concretizes (if necessary) and shows
the concretized environment. If you run `spack concretize` *first*, inspecting the
environment repeatedly with `spack spec` will be fast, as everything is already in the
`spack.lock` file.
- [x] factor most logic of `Spec.tree()` out of `Spec` class into `spack.spec.tree()`,
which can take multiple specs as roots.
- [x] make `Spec.tree()` call `spack.spec.tree()`

- [x] Update `spack concretize`
- [x] Update `spack install`
- [x] Update `spack spec` to call `spack.spec.tree()` for environments.
- [x] Continue to output specs individually for `spack spec` when using
`--yaml` or `--json`
`BuildcacheBootstrapper` uses `Spec.intersects` to match specs needed
for bootstrapping against the binary cache. The specs were not
sufficiently-detailed to prevent matching e.g. cached binaries for
Mac OS on Windows; this commit adds the platform to each requested
bootstrap spec to prevent that.
Remove support for `cray` as a separate platform.
Any platform previously detected as `cray` is now detected as `linux`.

Fixes a bug in the concretizer where specs depending on a host
incompatible libc would be used. This bug triggers when nothing is
built.
In the case where everything is reused, there is no libc provider from
the perspective of the solver, there is only compatible_libc. This
commit ensures that we require a host compatible libc on any reused
spec, additionally to requiring compat with the chosen libc provider.

Change the installer to take `([pkg], args)` in the constructor instead
of `[(pkg, args)]`. The reason is that certain arguments are global
settings, and the new API ensures that those arguments cannot be
different across different "build requests".
The `explicit` install arg is now a list of hashes, and the installer is
no longer responsible for determining what package is installed
explicitly. This way environment installs can simply pass the list of
environment roots, without them necessarily being explicit build
requests. For example an env with two roots [a, b], where b depends on
a, would not always cause spack install to mark b as explicit.
Notice that `overwrite` already took a list of hashes, this makes
`explicit` consistent.
`package.do_install(explicit=True)` continues to take a boolean.
The windows wrappers for basic functions like `os.symlink`,
`os.readlink` and `os.path.islink` in the `llnl.util.symlink` module
have bugs, and trigger more file system operations on non-windows than
they should.
This commit just binds `llnl.util.symlink.symlink = os.symlink` etc so
built-in functions are used on non-windows
`spack clean <spec>` will now resolve specs based on the active environment if one is active.
If an env is active but no matching spec is found, this will fall back on fully concretizing.
Before this PR, if Spack could see a possibility to reuse a spec that
doesn't match a strong preference, it would do so. After the PR, a
strong preference would take precedence.
avoid calling `spec.target` when None.
When an external compiler package has an `os` set but no `target` set, Spack
currently falls into a codepath that calls `spec.target` (which itself calls
`spec.architecture.target.Microarchitecture`) when `spec.architecture.target`
is None, throwing an error.
e.g.
```
packages:
gcc:
externals:
- spec: gcc@12.3.1 os=rhel7

This fixes a bug occurring when two root specs need to select
old versions, and these versions have the same penalty in the
optimization. This sometimes caused an older version to be
preferred to a more recent one.
The issue was the omission of `PackageNode` in the optimization
tuple.
Use correct path separator in get_all_package_diffs for all platforms.
Ensures correct package change computation on Windows when pruning unchanged specs in Gitlab CI
This fixes an issue where ghcr, gitlab and possibly other container registries paginate tags by default, which violates the OCI spec v1.0, but is common practice (the spec was broken itself). After this commit, you can create build cache indices of > 100 specs on ghcr.

Symlinks on Windows can use longpath prefixes (\\?\); these are fine
in the context of win32 API interactions but break numerous facets of
Spack behavior that rely on string parsing/matching (archiving,
binary distributions, tarball extraction, view regen, etc).
Spack's internal readlink method (llnl.util.symlink.readlink)
gracefully handles this by removing the prefix and otherwise behaving
exactly as os.readlink does, so we should prefer that in all cases.
Apparently urllib can throw a range of different exceptions:
1. HTTPError
2. URLError with e.reason set to the actual exception
3. TimeoutError from getresponse, which is not wrapped
* archive: relative links only
Ensure all links written into tarfiles generated from Spack prefixes do not contain symlinks pointing outside the prefix
* binary_distribution: limit extraction to prefix
Ensure files extracted from spackballs are not links pointing outside of the prefix
* Ensure rpaths are properly set on Windows
* hard error on extraction of absolute links
* refactor for non link-modifying approach
* Restore tarball extraction to original impl
* use custom readlink
* cleanup symlink module
* make lstrip
Add the ability to include any number of (potentially nested) concrete environments, e.g.:
```yaml
spack:
specs: []
concretizer:
unify: true
include_concrete:
- /path/to/environment1
- /path/to/environment2
```
or, from the CLI:
```console
$ spack env create myenv
$ spack -e myenv add python
$ spack -e myenv concretize
$ spack env create --include-concrete myenv included_env
```
The contents of included concrete environments' spack.lock files are
included in the environment's lock file at creation time. Any changes
to included concrete environments are only reflected after the environment
is re-concretized from the re-concretized included environments.

Currently SPACK_COLOR=always is not respected in the build process on
macOS, because the global `_force_color` is re-evaluated in global scope
during module setup, where it is always `None`.
So, move global init bits from main.py to the module itself.
Some specs which were excluded from reuse,
are currently added back to the solve when
we traverse dependencies of other reusable
specs.
This fixes the issue by keeping track of what
we can explicitly reuse.
This commit adds a layer of indirection to improve build isolation with
and without external Python, as well as usability of environment views.
It adds `python-venv` as a dependency to all packages that `extends("python")`,
which has the following advantages:
1. Build isolation: only `PYTHONPATH` is considered in builds, not
user / system packages
2. Stable install layout: fixes the problem on Debian, RHEL and Fedora where
external / system python produces `bin/local` subdirs in Spack install prefixes.
3. Environment views are Python virtual environments (and if you add
`py-pip` things like `pip list` work)
Views work whether they're symlink, hardlink or copy type.
This commit additionally makes `spec["python"].command` return
`spec["python-venv"].command`. The rationale is that packages in repos we do
not own do not pass the underlying python to the build system, which could still
result in incorrectly computed install layouts.
Other attributes like `libs`, `headers` should be on `python` anyways and need no change.
Currently bootstrapping from source fails because clingo requires gnupg
requires clingo.
This commit stops eager bootstrapping. We don't need `patchelf` nor `gnupg`
generally. They're bootstrapped when needed.
This creates shared infrastructure for compiler packages to implement the
detailed search capabilities from the `spack compiler find` command for the
`spack external find` command.
After this commit, `spack compiler find` can be replaced with
`spack external find --tag compiler`, with the exception of mixed toolchains.
A named env cannot contain `.` and `/`.
So when a user runs `spack env create ./here` do not error but treat it
as `spack env create -d ./here`.
Also fix help string of `spack env create`, which seems to have been
copied from `activate` incorrectly.
Since reuse is the default now, `--reuse-deps` can be confusing, as it
technically does not imply roots are fresh.
So add `--fresh-roots`, which is also easier to discover when running
`spack concretize --fre<tab>`
We recently switched to using the new ReadTheDocs with "addons". That includes its own
analytics, which is nice, but we also want to continue using our GA4 analytics.
Adding GA4 is no longer supported by RTD, so we have to add it manually.

Adds a pre-concretization check for the Windows SDK and WGL (Windows
GL) packages as non-buildable externals.
This is a redo of https://github.com/spack/spack/pull/43459, but makes
sure to modify the configuration scope outside of the bootstrap scope:
whichever is highest-precedence in the user's environment at the time
the concretization runs, which should either be an env scope or the
~ scope.
Adds pytest fixture mocking the check for WGL and WSDK as if they were
present.
This PR gives users finer control over which specs are reused during concretization.
The value of the `concretizer:reuse` config option now can take an object with the following properties:
- `roots`: true if reusing roots, false if reusing just dependencies
- `exclude`: list of constraints used to select reusable specs
- `include`: list of constraints used to select reusable specs
- `from`: allows to select the sources of reused specs
### Examples
#### Reuse only specs compiled with GCC
```yaml
concretizer:
reuse:
roots: true
include:
- "%gcc"
```
#### `openmpi` must be used from externals, and it must be the only external used
```yaml
concretizer:
reuse:
roots: true
from:
- type: local
exclude:
- "openmpi"
- type: buildcache
exclude:
- "openmpi"
- type: external
include:
- "openmpi"
```
* PackageStillNeededError: add pkg that needs spec to exception msg
* PackageStillNeededError: f-string with short fmt and hash
* PackageStillNeededError: split long string
The old concretizer creates a cyclic graph when expanding virtuals for
`iconv`, which is a bug. This hack drops glibc and musl as possible
providers for `iconv` in the old concretizer to work around it.
Add debug log for external detection tests. The debug log
is used to print which test is being executed.
Skip version audit on Windows where appropriate
We run `extend spack_flags_list SPACK_LDFLAGS` for `$mode in ld|ccld`.
That's problematic, cause `ccld` needs `-Wl,--flag` whereas `ld` needs
`--flag` directly. Only `-L` and `-l` are common to compiler & linker.
In all build systems `LDFLAGS` is for the compiler not the linker, cause
any linker flag `-x` can be passed as a compiler flag `-Wl,-x`, and there
are many compiler flags that affect the linker invocation, like `-fopenmp`,
`-fuse-ld=`, `-fsanitize=` etc.
So don't pass `LDFLAGS` to the linker directly.
This way users can set `ldflags: -Wl,--allow-shlib-undefined` in compilers.yaml
to work around an issue where the linker tries to resolve the `libcuda.so.1`
stub lib which cannot be located by design in `cuda`.
Some packages can't be redistributed in source or binary form. We need an explicit way to say that in a package.
This adds a `redistribute()` directive so that package authors can write, e.g.:
```python
redistribute(source=False, binary=False)
```
You can also do this conditionally with `when=`, as with other directives, e.g.:
```python
# 12.0 and higher are proprietary
redistribute(source=False, binary=False, when="@12.0:")
# can't redistribute when we depend on some proprietary dependency
redistribute(source=False, binary=False, when="^proprietary-dependency")
```
To prevent Spack from adding either their sources or binaries to public mirrors and build caches. You can still unconditionally add things *if* you run either:
* `spack mirror create --private`
* `spack buildcache push --private`
But the default behavior for build caches is not to include non-redistributable packages in either mirrors or build caches. We have previously done this manually for our public buildcache, but with this we can start maintaining redistributability directly in packages.
Caveats: currently the default for `redistribute()` is `True` for both `source` and `binary`, and you can only set either of them to `False` via this directive.
- [x] add `redistribute()` directive
- [x] add `redistribute_source` and `redistribute_binary` class methods to `PackageBase`
- [x] add `--private` option to `spack mirror`
- [x] add `--private` option to `spack buildcache push`
- [x] test exclusion of packages from source mirror (both as a root and as a dependency)
- [x] test exclusion of packages from binary mirror (both as a root and as a dependency)
If there's no compiler we currently don't have any external libc for the solver.
This commit adds a fallback on libc from the current Python process, which works if it is dynamically linked.

When looking at where we spend our time in solver setup, I noticed a fair bit of time is spent
in `Spec.format()`, and `Spec.format()` is a pretty old, slow, convoluted method.
This PR does a number of things:
- [x] Consolidate most of what was being done manually with a character loop and several
regexes into a single regex.
- [x] Precompile regexes where we keep them
- [x] Remove the `transform=` argument to `Spec.format()` which was only used in one
place in the code (modules) to uppercase env var names, but added a lot of complexity
- [x] Avoid escaping and colorizing specs unless necessary
- [x] Refactor a lot of the colorization logic to avoid unnecessary object construction
- [x] Add type hints and remove some spots in the code where we were using nonexistent
arguments to `format()`.
- [x] Add trivial cases to `__str__` in `VariantMap` and `VersionList` to avoid sorting
- [x] Avoid calling `isinstance()` in the main loop of `Spec.format()`
- [x] Don't bother constructing a `string` representation for the result of `_prev_version`
as it is only used for comparisons.
In my timings (on all the specs formatted in a solve of `hdf5`), this is over 2.67x faster than the
original `format()`, and it seems to reduce setup time by around a second (for `hdf5`).
The reverse provider lookup may have stale entries for deleted packages, which used to cause errors. It's hard to invalidate those cache entries, so this commit simply drops entries w/o invalidating the cache.

This commit differentiate linux from other platforms by
using libc compatibility as a criterion for deciding
which buildcaches / binaries can be reused. Other
platforms still use OS compatibility.
On linux a libc is injected by all compilers as an implicit
external, and the compatibility criterion is that a libc is
compatible with all other libcs with the same name and a
version that is lesser or equal.
Some concretization unit tests use libc when run on linux.
Some logic to detect what libc the c / cxx compilers use by default,
based on `-dynamic-linker`.
The function `compiler.default_libc()` returns a `Spec` of the form
`glibc@x.y` or `musl@x.y` with the `external_path` property set.
The idea is this can be injected as a dependency.
If we can't run the dynamic linker directly, fall back to `ldd` relative
to the prefix computed from `ld.so.`
In the future we may transform the database from a single JSON object to
a stream of JSON objects.
This paves the way for constant time writes and constant time rereads
when only O(1) changes are made. Currently both are linear time.
This commit gives just enough forward compat for Spack to produce a
friendly error when we would move to a stream of json objects, and a db
would look like this:
```json
{"database": {"version": "<something newer>"}}
```
* compiler wrapper: prioritize spack managed paths in search order
This commit partitions search paths of -L, -I (and -rpath) into three
groups, from highest priority to lowest:
1. Spack managed directories: these include absolute paths such as
stores and the stage dir, as well as all relative paths since they
are relative to a Spack owned dir
2. Non-system dirs: these are for externals that live in non-system
locations
3. System dirs: your typical `/usr/lib` etc.
It's very easy for Spack to known the prefixes it owns, it's much more
difficult to tell system dirs from non-system dirs. Before this commit
Spack tried to distinguish only system and non-system dirs, and failed
for very trivial cases like `/usr/lib/x/..` which comes up often, since
build systems sometimes copy search paths from `gcc -print-search-dirs`.
Potentially this implementation is even faster than the current state of
things, since a loop over paths is replaced with an eval'ed `case ...`.
* Trigger a pipeline
* Revert "Trigger a pipeline"
This reverts commit 5d7fa863de.
* remove redudant return statement
* Later versions of oneAPI have moved, so update detection to find it
in both old and new location
* Remove reliance on ONEAPI_ROOT env variable when determining Fortran
compiler version for %msvc
* When finding a Fortran compiler for MSVC, there was logic enforcing
a maximum MSVC version for a given oneAPI Fortran version. This
mapping was out of date and excluding valid combinations, so has
been removed (the logic now just picks the latest available
oneAPI Fortran compiler for any given MSVC version).
On Windows, bootstrapping logic now searches for and adds the win-sdk
and wgl packages to the user's top scope as externals if they are not
present.
These packages are generally required to install most packages with
Spack on Windows, and are only available as externals, so it is
assumed that doing this automatically would be useful and avoid
a mandatory manual step for each new Spack instance.
Note this is the first case of bootstrapping logic modifying
configuration other than the bootstrap configuration.
This adds some improvements to `spack find` output when in environments based
around some thoughts about what users want to know when they're in an env.
If you're working in an enviroment, you mostly care about:
* What are the roots
* Which ones are installed / not installed
* What's been added that still needs to be concretized
So, this PR adds a couple tweaks to display that information more clearly:
- [x] We now display install status next to every root. You can easily see
which are installed and which aren't.
- [x] When you run `spack find -l` in an env, the roots now show their concrete
hash (if they've been concretized). They previously would show `-------`
(b/c the root spec itself is abstract), but showing the concretized root's
hash is a lot more useful.
- [x] Newly added/unconcretized specs still show `-------`, which now makes more
sense, b/c they are not concretized.
- [x] There is a new option, `-r` / `--only-roots` to *only* show env roots if
you don't want to look at all the installed specs.
- [x] Roots in the installed spec list are now highlighted as bold. This is
actually an old feature from the first env implementation , but various
refactors had disabled it inadvertently.
Reduce incidence of spurious errors by:
* Ensuring we're passing the buffer by reference
* Get the correct short string size from Windows API instead of computing ourselves
* Ensure sufficient space for null terminator character
Add test for `windows_sfn`
Currently if you request pkg +example where example is a conditional
variant, and you have a pkg in the database for which the condition
did not hold (so no +example nor ~example), the solver would reuse it
regardless, not imposing +example.
The change rules out exactly one thing: variant_set without variant_value,
which in practice could only happen when not node_has_variant (i.e. when
under the current package.py rules the variant's when condition did not
trigger).
Currently, some of the tests in `spec_format` and `spec_semantics` fetch
the actual zlib repository when run, because they call `str()` on specs
like `zlib@foo/bar`, which at least currently requires a remote git clone
to resolve.
This doesn't change the behavior of git versions, but it uses our mock git
repo infrastructure and clones the `git-test` package instead of the *real*
URL from the mock `zlib` package.
This should speed up tests. We could probably refactor more so that the git
tests *all* use such a fixture, but the `checks` field that unfortunately
tightly couples the mock git repository and the `git_fetch` tests complicates
this. We could also consider *not* making `str()` resolve git versions, but
I did not dig into that here.
- [x] add a mock_git_test_package fixture that sets up a mock git repo *and*
monkeypatches the `git-test` package (like our git test packages do)
- [x] use fixture in `test_spec_format_path`
- [x] use fixture in `test_spec_format_path_posix`
- [x] use fixture in `test_spec_format_path_windows`
- [x] use fixture in `test_parse_single_spec`
Upon close inspection of clingo answer sets, in some cases we have "equivalent" (i.e. same hash for the concrete spec) duplicates that differ only because of virtual nodes that are added to the answer set, without any edge using them.
This commit adds a property `autopush` to mirrors. When true, every source build is immediately followed by a push to the build cache. This is useful in ephemeral environments such as CI / containers.
To enable autopush on existing build caches, use `spack mirror set --autopush <name>`. The same flag can be used in `spack mirror add`.
Allow reuse of specs that were built with compilers not in the current configuration. This means that specs from build caches don't need to have a matching compiler locally to be reused. Similarly when updating a distro. If a node needs to be built, only available compilers will be considered as candidates.
* Generally use os.replace on Windows and Linux
* Windows behavior for os.replace differs when the destination exists
and is a symlink to a directory: on Linux the dst is replaced and
on Windows this fails - this PR makes Windows behave like Linux
(by deleting the dst before doing the rename unless src and dst
are the same)
* Relax compiler and target mismatches
The mismatch occurs on an edge. Previously it was assigned
the parent priority, now it is assigned the child priority.
This should make reuse from buildcaches or store more likely,
since most mismatches will be counted with "reused" priority.
* Optimize version badness for runtimes at very low priority
We don't want to e.g. switch other attributes because we
cannot reuse an old installed runtime.
* Optimize runtime attributes at very low priority
This is such that the version of the runtime would
not influence whether we should reuse a spec.
Compiler mismatches are considered for runtimes,
to avoid situations where compiling foo%gcc@9
brings in gcc-runtime%gcc@13 if gcc@13 is among
the available compilers
* Exclude specs without runtimes from reuse
This should ensure that we do not reuse specs that
could be broken, as they expect the compiler to be
installed in a specific place.
The installer runs `get_dependent_ids`, which follows edges outside the
subdag that's being installed, so it returns a superset of the actual
dependents.
That's generally fine, except that it calls `s.package` on every
dependent, which triggers a package class to be instantiated, which is a
lot of work.
Instead, compute the package id from the spec, since that's all that's
used anyways and does not trigger *lots* of slow and redundant
instantiations of package objects.
If ONEAPI_ROOT is not set as an environment variable, the current approach will raise an error.
Instead we can compute the OneAPI_ROOT from the compiler paths like we do with vcvarsall.
`dpcpp` is deprecated by intel and has been superseded by `oneapi` compilers for a very long time.

This PR allows the user to specify a path to a custom cert file (or directory) in
Spack's config:
```yaml
# This is where custom certs for proxy/firewall are stored.
# It can be a path or environment variable. To match ssl env configuration
# the default is the environment variable SSL_CERT_FILE
ssl_certs: $SSL_CERT_FILE
```
`config:ssl_certs` can be a path to a file or a directory, or it can be and environment
variable that resolves to one of those. When it posts to something valid, Spack will
update the ssl context to include custom certs, and fetching via `urllib` and `curl`
will trust the provided certs.
This should resolve many issues with fetching behind corporate firewalls.

After #41373, where we stopped considering the source directory to be the stage for develop builds,
we resumed *deleting* the stage even after a successful build.
We don't want this for develop builds because developers need to iterate; we should keep the artifacts
unless they explicitly run `spack clean`.
Now:
- [x] Build artifacts for develop packages are not removed after a successful install
- [x] They are also not removed before an install starts, i.e. develop packages always
reuse prior artifacts, if available.
- [x] They can be deleted in any other context, e.g. by running `spack clean --stage`
Users requested an option to filter between local/upstream results in `spack find` output.
```
# default behavior, same as without --install-tree argument
$ spack find --install-tree all
# show only local results
$ spack find --install-tree local
# show results from all upstreams
$ spack find --install-tree upstream
# show results from a particular upstream or the local install_tree
$ spack find --install-tree /path/to/install/tree/root

This PR adds:
- A new runtime for `%oneapi` compilers, called `intel-oneapi-runtime`
- Information to both `gcc-runtime` and `intel-oneapi-runtime`, to ensure
that we don't mix compilers using different soname for either `libgfortran`
or `libifcore`
To do so, the following internal mechanisms have been implemented:
- Possibility to inject virtual dependencies from the `runtime_constraints`
callback on packages
Information has been added to `gcc-runtime` to provide the correct soname
under different conditions on its `%gcc`.

This adds support for prereleases. Alpha, beta and release candidate
suffixes are ordered in the intuitive way:
```
1.2.0-alpha < 1.2.0-alpha.1 < 1.2.0-beta.2 < 1.2.0-rc.3 < 1.2.0 < 1.2.0-xyz
```
Alpha, beta and rc prereleases are defined as follows: split the version
string into components like before (on delimiters and string boundaries).
If there's a string component `alpha`, `beta` or `rc` followed by an optional
numeric component at the end, then the version is prerelease.
So `1.2.0-alpha.1 == 1.2.0alpha1 == 1.2.0.alpha1` are all the same, as usual.
The strings `alpha`, `beta` and `rc` are chosen because they match semver,
they are sufficiently long to be unambiguous, and and all contain at least
one non-hex character so distinguish them from shasum/digest type suffixes.
The comparison key is now stored as `(release_tuple, prerelease_tuple)`, so in
the above example:
```
((1,2,0),(ALPHA,)) < ((1,2,0),(ALPHA,1)) < ((1,2,0),(BETA,2)) < ((1,2,0),(RC,3)) < ((1,2,0),(FINAL,)) < ((1,2,0,"xyz"), (FINAL,))
```
The version ranges `@1.2.0:` and `@:1.1` do *not* include prereleases of
`1.2.0`.
So for packaging, if the `1.2.0alpha` and `1.2.0` versions have the same constraints on
dependencies, it's best to write
```python
depends_on("x@1:", when="@1.2.0alpha:")
```
However, `@1.2:` does include `1.2.0alpha`. This is because Spack considers
`1.2 < 1.2.0` as distinct versions, with `1.2 < 1.2.0alpha < 1.2.0` as a consequence.
Alternatively, the above `depends_on` statement can thus be written
```python
depends_on("x@1:", when="@1.2:")
```
which can be useful too. A short-hand to include prereleases, but you
can still be explicit to exclude the prerelease by specifying the patch version
number.
### Concretization
Concretization uses a different version order than `<`. Prereleases are ordered
between final releases and develop versions. That way, users should not
have to set `preferred=True` on every final release if they add just one
prerelease to a package. The concretizer is unlikely to pick a prerelease when
final releases are possible.
### Limitations
1. You can't express a range that includes all alpha release but excludes all beta
releases. Only alternative is good old repeated nines: `@:1.2.0alpha99`.
2. The Python ecosystem defaults to `a`, `b`, `rc` strings, so translation of Python versions to
Spack versions requires expansion to `alpha`, `beta`, `rc`. It's mildly annoying, because
this means we may need to compute URLs differently (not done in this commit).
### Hash
Care is taken not to break hashes of versions that do not have a prerelease
suffix.

Running a `spack-python` script like this:
```python
import spack
import multiprocessing
def echo(args):
print(args)
if __name__ == "__main__":
pool = multiprocessing.Pool(2)
pool.map(echo, range(10))
```
will fail in `develop` with an error like this:
```console
_pickle.PicklingError: Can't pickle <function echo at 0x104865820>: attribute lookup echo on __main__ failed
```
Python expects to be able to look up the method `echo` in `sys.path["__main__"]` in
subprocesses spawned by `multiprocessing`, but because we use `InteractiveConsole` to
run `spack python`, the executed file isn't considered to be the `__main__` module, and
lookups in subprocesses fail. We tried to fake this by setting `__name__` to `__main__`
in the `spack python` command, but that doesn't fix the fact that no `__main__` module
exists.
Another annoyance with `InteractiveConsole` is that `__file__` is not defined in the
main script scope, so you can't use it in your scripts.
We can use the [runpy.run_path()](https://docs.python.org/3/library/runpy.html#runpy.run_path) function,
which has been around since Python 3.2, to fix this.

- [x] Only use `InteractiveConsole` for interactive `spack python`
Often in containers, the files we use to detect whether a cray system supports new features are not available.
Given that the cray containers only support the newer versions, and that these versions have been
around for a while at this point and few sites don't support them, this PR changes the logic for
detecting cray systems so that:
1. Don't even consider whether something is the `cray` platform if `opt/cray` is not in `MODULEPATH`
2. Only use the `cray` platform if we can read files in /opt/cray/pe and positively detect an older version
3. Otherwise, assume we're *not* on a cray (includes newer Cray PE's, which we treat as Linux)
`jinja2` can be a costly import, and right now it happens at startup every time we run
Spack. This slows down `spack --print-shell-vars` a bit, which is needed by `setup-env.*sh`.
Patch allowing Clingo to build with VS22 has landed both in Spack
and Clingo upstream, update Spack's bootstrap constraints to handle
this.
Additionally, properly scope the patch application in the clingo
package to handle upstream patch.
