The CMake builder in Spack actually adds incorrect rpaths. They are
unfiltered and incorrectly ordered compared to what the compiler wrapper
adds.
There is no need to specify paths to dependencies in `CMAKE_INSTALL_RPATH`
because of two reasons:
1. CMake preserves "toolchain" rpaths, which includes the rpaths injected
by our compiler wrapper.
2. We use `CMAKE_INSTALL_RPATH_USE_LINK_PATH=ON`, so libraries we link
to are rpath'ed automatically.
However, CMake does not create install rpaths to directories in the package's
own install prefix, so we set `CMAKE_INSTALL_RPATH` to the educated guess
`<prefix>/{lib,lib64}`, but omit dependencies.
Some assertion are not testing DAG invariants, and they are passing only
because of the simple structure of the builtin.mock repository on develop.

This PR allows users to configure explicit splicing replacement of an abstract spec in the concretizer.
concretizer:
splice:
explicit:
- target: mpi
replacement: mpich/abcdef
transitive: true
This config block would mean "for any spec that concretizes to use mpi, splice in mpich/abcdef in place of the mpi it would naturally concretize to use. See #20262, #26873, #27919, and #46382 for PRs enabling splicing in the Spec object. This PR will be the first place the splice method is used in a user-facing manner. See https://spack.readthedocs.io/en/latest/spack.html#spack.spec.Spec.splice for more information on splicing.
This will allow users to reuse generic public binaries while splicing in the performant local mpi implementation on their system.
In the config file, the target may be any abstract spec. The replacement must be a spec that includes an abstract hash `/abcdef`. The transitive key is optional, defaulting to true if left out.
Two important items to note:
1. When writing explicit splice config, the user is in charge of ensuring that the replacement specs they use are binary compatible with whatever targets they replace. In practice, this will likely require either specific knowledge of what packages will be installed by the user's workflow, or somewhat more specific abstract "target" specs for splicing, to ensure binary compatibility.
2. Explicit splices can cause the output of the concretizer not to satisfy the input. For example, using the config above and consider a package in a binary cache `hdf5/xyzabc` that depends on mvapich2. Then the command `spack install hdf5/xyzabc` will instead install the result of splicing `mpich/abcdef` into `hdf5/xyzabc` in place of whatever mvapich2 spec it previously depended on. When this occurs, a warning message is printed `Warning: explicit splice configuration has caused the the concretized spec {concrete_spec} not to satisfy the input spec {input_spec}".
Highlighted technical details of implementation:
1. This PR required modifying the installer to have two separate types of Tasks, `RewireTask` and `BuildTask`. Spliced specs are queued as `RewireTask` and standard specs are queued as `BuildTask`. Each spliced spec retains a pointer to its build_spec for provenance. If a RewireTask is dequeued and the associated `build_spec` is neither available in the install_tree nor from a binary cache, the RewireTask is requeued with a new dependency on a BuildTask for the build_spec, and BuildTasks are queued for the build spec and its dependencies.
2. Relocation is modified so that a spack binary can be simultaneously installed and rewired. This ensures that installing the build_spec is not necessary when splicing from a binary cache.
3. The splicing model is modified to more accurately represent build dependencies -- that is, spliced specs do not have build dependencies, as spliced specs are never built. Their build_specs retain the build dependencies, as they may be built as part of installing the spliced spec.
4. There were vestiges of the compiler bootstrapping logic that were not removed in #46237 because I asked alalazo to leave them in to avoid making the rebase for this PR harder than it needed to be. Those last remains are removed in this PR.

On sysroot systems like gentoo prefix, as well as nix/guix, our "is
system path" logic is broken cause it's static.
Talking about "the system paths" is not helpful, we have to talk
about default search paths of the dynamic linker instead.
If glibc is recent enough, we can query the dynamic loader's default
search paths, which is a much more robust way to avoid registering
rpaths to system dirs, which can shadow Spack dirs.
This PR adds an **additional** filter on rpaths the compiler wrapper
adds, dropping rpaths that are default search paths. The PR **does
not** remove any of the original `is_system_path` code yet.
This fixes issues where build systems run just-built executables
linked against their *not-yet-installed libraries*, typically:
```
LD_LIBRARY_PATH=. ./exe
```
which happens in `perl`, `python`, and other non-cmake packages.
If a default path is rpath'ed, it takes precedence over
`LD_LIBRARY_PATH`, and a system library gets loaded instead
of the just-built library in the stage dir, breaking the build. If
default paths are not rpath'ed, then LD_LIBRARY_PATH takes
precedence, as is desired.
This PR additionally fixes an inconsistency in rpaths between
cmake and non-cmake packages. The cmake build system
computed rpaths by itself, but used a different order than
computed for the compiler wrapper. In fact it's not necessary
to compute rpaths at all, since we let cmake do that thanks to
`CMAKE_INSTALL_RPATH_USE_LINK_PATH`. This covers rpaths
for all dependencies. The only install rpaths we need to set are
`<install prefix>/{lib,lib64}`, which cmake unfortunately omits,
although it could also know these. Also, cmake does *not*
delete rpaths added by the toolchain (i.e. Spack's compiler
wrapper), so I don't think it should be controversial to simplify
things.
The current `Spec.splice` model is very limited by the inability to splice specs that
contain multiple nodes with the same name. This is an artifact of the original
algorithm design predating the separate concretization of build dependencies,
which was the first feature to allow multiple specs in a DAG to share a name.
This PR provides a complete reimplementation of `Spec.splice` to avoid that
limitation. At the same time, the new algorithm ensures that build dependencies
for spliced specs are not changed, since the splice by definition cannot change
the build-time information of the spec. This is handled by splitting the dependency
edges and link/run edges into separate dependencies as needed.

macOS Sequoia's linker will complain if RPATHs on the CLI are specified more than once.
To avoid errors due to this, make `cc` only append unique RPATHs to the final args list.
This required a few improvements to the logic in `cc`:
1. List functions in `cc` didn't have any way to append unique elements to a list. Add a
`contains()` shell function that works like our other list functions. Use it to implement
an optional `"unique"` argument to `append()` and an `extend_unique()`. Use that to add
RPATHs to the `args_list`.
2. In the pure `ld` case, we weren't actually parsing `RPATH` arguments separately as we
do for `ccld`. Fix this by adding *another* nested case statement for raw `RPATH`
parsing. There are now 3 places where we deal with `-rpath` and friends, but I don't
see a great way to unify them, as `-Wl,`, `-Xlinker`, and raw `-rpath` arguments are
all ever so slightly different.
3. Fix ordering of assertions to make `pytest` diffs more intelligible. The meaning of
`+` and `-` in diffs changed in `pytest` 6.0 and the "preferred" order for assertions
became `assert actual == expected` instead of the other way around.

If `add_padding()` is allowed to return a path with a trailing path
separator, it will get collapsed elsewhere in Spack. This can lead to

This PR introduces a new heuristic for the solver, which behaves better when
compilers are treated as nodes. Apparently, it performs better also on `develop`,
where compilers are still node attributes.
The new heuristic:
- Sets an initial priority for guessing a few attributes. The order is "nodes" (300),
"dependencies" (150), "virtual dependencies" (60), "version" and "variants" (30), and
"targets" and "compilers" (1). This initial priority decays over time during the solve, and
falls back to the defaults.
- By default, it considers most guessed facts as "false". For instance, by default a node
doesn't exist in the optimal answer set, or a version is not picked as a node version etc.
- There are certain conditions that override the default heuristic using the _priority_ of
a rule, which previously we didn't use. For instance, by default we guess that a
`attr("variant", Node, Variant, Value)` is false, but if we know that the node is already
in the answer set, and the value is the default one, then we guess it is true.

While the existing getting started guide does in fact reference the

explicit, upfront mentions of the powershell support. Additionally
this PR adds notes about some of the issues with certain components
of the spec syntax when using CMD.
Removes `spack.package_base.PackageBase.do_{install,deprecate}` in favor of
`spack.installer.PackageInstaller.install` and `spack.installer.deprecate` resp.
That drops a dependency of `spack.package_base` on `spack.installer`, which is
necessary to get rid of circular dependencies in Spack.
Also change the signature of `PackageInstaller.__init__` from taking a dict as
positional argument, to an explicit list of keyword arguments.
Continuing the work started in #40326, his changes the structure
of Variant metadata on Packages from a single variant definition
per name with a list of `when` specs:
```
name: (Variant, [when_spec, ...])
```
to a Variant definition per `when_spec` per name:
```
when_spec: { name: Variant }
```
With this change, everything on a package *except* versions is
keyed by `when` spec. This:
1. makes things consistent, in that conditional things are (nearly)
all modeled in the same way; and
2. fixes an issue where we would lose information about multiple
variant definitions in a package (see #38302). We can now have,
e.g., different defaults for the same variant in different
versions of a package.
Some notes:
1. This required some pretty deep changes to the solver. Previously,
the solver's job was to select value(s) for a single variant definition
per name per package. Now, the solver needs to:
a. Determine which variant definition should be used for a given node,
which can depend on the node's version, compiler, target, other variants, etc.
b. Select valid value(s) for variants for each node based on the selected
variant definition.
When multiple variant definitions are enabled via their `when=` clause, we will
always prefer the *last* matching definition, by declaration order in packages. This
is implemented by adding a `precedence` to each variant at definition time, and we
ensure they are added to the solver in order of precedence.
This has the effect that variant definitions from derived classes are preferred over
definitions from superclasses, and the last definition within the same class sticks.
This matches python semantics. Some examples:
```python
class ROCmPackage(PackageBase):
variant("amdgpu_target", ..., when="+rocm")
class Hipblas(ROCmPackage):
variant("amdgpu_target", ...)
```
The global variant in `hipblas` will always supersede the `when="+rocm"` variant in
`ROCmPackage`. If `hipblas`'s variant was also conditional on `+rocm` (as it probably
should be), we would again filter out the definition from `ROCmPackage` because it
could never be activated. If you instead have:
```python
class ROCmPackage(PackageBase):
variant("amdgpu_target", ..., when="+rocm")
class Hipblas(ROCmPackage):
variant("amdgpu_target", ..., when="+rocm+foo")
```
The variant on `hipblas` will win for `+rocm+foo` but the one on `ROCmPackage` will
win with `rocm~foo`.
So, *if* we can statically determine if a variant is overridden, we filter it out.
This isn't strictly necessary, as the solver can handle many definitions fine, but
this reduces the complexity of the problem instance presented to `clingo`, and
simplifies output in `spack info` for derived packages. e.g., `spack info hipblas`
now shows only one definition of `amdgpu_target` where before it showed two, one of
which would never be used.
2. Nearly all access to the `variants` dictionary on packages has been refactored to
use the following class methods on `PackageBase`:
* `variant_names(cls) -> List[str]`: get all variant names for a package
* `has_variant(cls, name) -> bool`: whether a package has a variant with a given name
* `variant_definitions(cls, name: str) -> List[Tuple[Spec, Variant]]`: all definitions
of variant `name` that are possible, along with their `when` specs.
* `variant_items() -> `: iterate over `pkg.variants.items()`, with impossible variants
filtered out.
Consolidating to these methods seems to simplify the code a lot.
3. The solver does a lot more validation on variant values at setup time now. In
particular, it checks whether a variant value on a spec is valid given the other
constraints on that spec. This allowed us to remove the crufty logic in
`update_variant_validate`, which was needed because we previously didn't *know* after
a solve which variant definition had been used. Now, variant values from solves are
constructed strictly based on which variant definition was selected -- no more
heuristics.
4. The same prevalidation can now be done in package audits, and you can run:
```
spack audit packages --strict-variants
```
This turns up around 18 different places where a variant specification isn't valid
given the conditions on variant definitions in packages. I haven't fixed those here
but will open a separate PR to iterate on them. I plan to make strict checking the
defaults once all existing package issues are resolved. It's not clear to me that
strict checking should be the default for the prevalidation done at solve time.
There are a few other changes here that might be of interest:
1. The `generator` variant in `CMakePackage` is now only defined when `build_system=cmake`.
2. `spack info` has been updated to support the new metadata layout.
3. split out variant propagation into its own `.lp` file in the `solver` code.
4. Add better typing and clean up code for variant types in `variant.py`.
5. Add tests for new variant behavior.
Openmpi provider statements were changed in #46102. The package change
was fine in and of itself, but apparently one of our tests depends on
the precise constraints used in those statements. I updated the test
to remove the checks for constraints that were removed.

Allow flags from different sources (compilers, `require:`, command-line
specs, and `depends_on`) to be merged together, and enforce a consistent
order among them.
The order is based on the sources, e.g. flags on specs from the command
line always come last. Some flag order consistency issues are fixed:
1. Flags from `compilers.yaml` and the command line were always intra- and
inter-source order consistent.
2. Flags from dependents and packages.yaml (introduced via `require:`)
were not: for `-a -b` from one source and `-c` from another, the final
result might rearrange `-a -b`, and would also be inconsistent in terms
of whether `-c` came before or after.
(1) is/was handled by going back to the original source, i.e., flags are
retrieved directly from the command line spec rather than the solver.
(2) is addressed by:
* Keeping track of grouped flags in the solver
* Keeping track of flag sources in the solver on a per-flag basis
The latter info is used in this PR to enforce DAG ordering on flags
applied from multiple dependents to the same package, e.g., for this
graph:
```
a
/|\
b | c
\|/
d
```
If `a`, `b`, and `c` impose flags on `d`, the combined flags on `d` will
contain the flags of `a`, `b`, and `c` -- in that order.
Conflicting flags are allowed (e.g. -O2 and -O3). `Spec.satisifes()` has
been updated such that X satisfies Y as long as X has *at least* all of
the flags that Y has. This is also true in the solver constraints.
`.satisfies` does not account for how order can change behavior (so
`-O2 -O3` can satisfy `-O3 -O2`); it is expected that this can be
addressed later (e.g. by prohibiting flag conflicts).
`Spec.constrain` and `.intersects` have been updated to be consistent
with this new definition of `.satisfies`.
Spack can now bootstrap two new dependencies on Windows: GnuPG, and file.
These dependencies are modeled as a separate package, and they install a cross-compiled binary.

Currently stacks behave differently if used in unify:false

This PR removes the best effort expansion, so that user specs

This PR simplifies the code doing external spec detection by removing

Source mirrors store entries by digest and add a human readable alias of the
form 'name-version'. If no digest is available, the alias is used as the primary
storage location.
Spack erroneously fetches by alias when the digest path does not exist. This is
problematic if `version(..., sha256=...)` changes in package.py, and the mirror
is populated with the old shasum. That would result in an error when a digest
is available, but in case of git versions with a modified commit sha, the wrong
sources would be fetched without error. With this PR, only the digest path is
used, not the alias, in case a digest is available. This is also a small performance
optimization, as the number of request is halved for mirrors that don't contain
the sources.
Further, for git sources the tag was used as a digest, but this is a moving
target. Only commit sha is used now.
Also whenever the alias already existed, Spack used to keep it in place when
updating the mirror cache, which means that aliases would always point to
outdated mirror entries whenever digests are modified. With this PR the alias
is moved in place.
Lastly, fix a recent regression where `Stage.disable_mirrors` disabled mirrors
but not the local download cache, which was the intention.

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

This commit makes it so that

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.
* Use absolute paths instead of https:// fake mirrors (this speed-up tests by avoiding requests)
* Add a fixture to gather in a single place code that is copy/pasted in a lot of tests
* General clean-up of tests and repeated code

* 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()`.
- [x] Bootstrap clingo concretization based on a JSON file
- [x] Bootstrap clingo *before* patchelf
- [x] Remove any use of the old concretizer, including:
* Remove only_clingo and only_original fixtures
* Remove _old_concretize and _new_concretize
* Remove _concretize_together_old
* Remove _concretize_together_new
* Remove any use of `SPACK_TEST_SOLVER`
* Simplify CI jobs
- [x] ensure bootstrapping `clingo` works on on Darwin and Windows
- [x] Raise an intelligible error when a compiler is missing
- [x] Ensure bootstrapping works on FreeBSD
- [x] remove normalize and related methods

`setup-env.sh` is meant to be sourced, not executed directly.
By revoking execution permissions, users who accidentally execute
the script will receive an error instead of seeing no effect.
* Remove execution permission from `setup-env.sh` and friends
* Don't make output file executable in `spack commands --update-completion`

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.

VC toolset versions 144 and 143 are both associated with the platform
toolset 143; this deviates from prior version choices made by the
MSVC devs; add a special case to report platform toolset version
as 143 when VC toolset version is >= 143 (this will need revisiting
for later releases).
This was missed in #45394 because we don't run unit tests for package PRs, and
`test_all_virtual_packages_have_default_providers`, which would've caught it, is a unit
test, not an audit.
- [x] add a default provider for `wasi-sdk` in `etc/spack/defaults/packages.yaml` (which
we require for all virtuals)
- [x] rework `test_all_virtual_packages_have_default_providers` as an audit called
`_ensure_all_virtual_packages_have_default_providers`

The `Executable` class emits a warning when you pass quoted arguments to it:
```
> spack pkg grep '"namespace"'
==> Warning: Quotes in command arguments can confuse scripts like configure.
The following arguments may cause problems when executed:
"namespace"
Quotes aren't needed because spack doesn't use a shell. Consider removing them.
If multiple levels of quotation are required, use `ignore_quotes=True`.
```
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
line, and if we pass a quoted string, we probably meant to.
- [x] make `ignore_quotes` an instance variable, not just an argument to ``__call__`
- [x] set `ignore_quotes` to `True` in `spack pkg grep`

* Several tests can be enabled on Windows with no changes to logic
(either the test logic or logic being tested)
* Test for `spack location` requires modification of the test logic,
but with a minor change can be enabled on Windows
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.
