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.
* Core change: logic for extracting RPATHs from modules may return
`None`: filter this out of the set of RPATHs that is auto-generated
* Core change: `CachedCMakePackage` no longer adds ldflags to
`CMAKE_STATIC_LINKER_FLAGS`: generally these flags are not appropriate
for static linking (e.g. invocation of `ar`)
* [mfem] Add version 4.7
* [mfem] Add variant for precision (single/double). Enforce consistency
for precision amongst mfem and hypre/petsc/mumps dependencies

old cxxstd values for newer versions of some dependencies)
* [hypre] In line with prior point, added support for specifying
precision

`superlu-dist+rocm`
* [hiop] add proper `raja`/`umpire`/`camp` version constraints for
`hiop` versions 0.3.99-0.4.x; require `+raja` for `+rocm`, and
add dependency on `hiprand` for `+rocm`
* [butterflypack, mfem, strumpack, suite-sparse] Require
`CRAYLIBS_{target-family}` env var to be defined
* [suite-sparse] versions `@7.4:` changed install location of headers:
add symlink from old location to new location
* [zlib-ng] Fix error where shared libs were not successfully built for
`%cce@17` (the build did not fail, but the finished `zlib-ng%cce@17`
install did not have shared libs)
* 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.
* python: simplify logic for avoiding pyvenv.cfg in copy views

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] `spack.environment.display_specs()` now uses `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`.
Users who still need platform=cray have to stick to Spack 0.22
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

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

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

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 ...`.

* Remove reliance on ONEAPI_ROOT env variable when determining Fortran

* 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`.
Rules injected into the solver looks like:
```prolog

```
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] Use `runpy` module to launch non-interactive `spack python` invocations
- [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.
Currently (outside of this PR) when you `spack develop` a path, this path is treated as the staging
directory (this means that for example all build artifacts are placed in the develop path).
This PR creates a separate staging directory for all `spack develop`ed builds. It looks like
```
# the stage root
/the-stage-root-for-all-spack-builds/
spack-stage-<hash>
# Spack packages inheriting CMakePackage put their build artifacts here
spack-build-<hash>/
```
Unlike non-develop builds, there is no `spack-src` directory, `source_path` is the provided `dev_path`.
Instead, separately, in the `dev_path`, we have:
```
/dev/path/for/foo/
build-{arch}-<hash> -> /the-stage-root-for-all-spack-builds/spack-stage-<hash>/
```
The main benefit of this is that build artifacts for out-of-source builds that are relative to
`Stage.path` are easily identified (and you can delete them with `spack clean`).
Other behavior added here:
- [x] A symlink is made from the `dev_path` to the stage directory. This symlink name incorporates
spec details, so that multiple Spack environments that develop the same path will not conflict
with one another
- [x] `spack cd` and `spack location` have added a `-c` shorthand for `--source-dir`
Spack builds can still change the develop path (in particular to keep track of applied patches),
and for in-source builds, this doesn't change much (although logs would not be written into
the develop path). Packages inheriting from `CMakePackage` should get this benefit
automatically though.
The `patch()` directive can now be invoked with `reverse=True` to apply a patch in reverse.
This is useful for reverting commits that caused errors in projects, even if only the forward
patch is available, e.g. via a GitHub commit patch URL.
`patch(..., reverse=True)` runs `patch -R` behind the scenes. This is a POSIX option so we
can expect it to be available on the `patch` command.

fixes#43097
Before this PR the behavior of mixins used together with
builders was to mask completely the callbacks defined from
the class coming later in the MRO.
Here we fix the behavior by accumulating all callbacks,
and de-duplicating them later.
Remove dependency on `importlib_metadata` and `pkg_resources`, which can be problematic if the version in PYTHONPATH is incompatible with the interpreter Spack is running under.

* ASP-based solver: improve reusing nodes with gcc-runtime
This PR skips emitting dependency constraints on "gcc-runtime",
for concrete specs that are considered for reuse.
Instead, an appropriate version of gcc-runtime is recomputed
considering also the concrete nodes from reused specs.
This ensures that root nodes in a DAG have always a runtime
that is at a version greater or equal than their dependencies.

Spack merges ranges and concrete versions if they have non-empty
intersection. That is not enough for adjacent version ranges.
This commit ensures that disjoint ranges in version lists are simplified
if their union is not disjoint:
```python
"@1.0:2.0,2.1,2.2:3,4:6" # simplifies to "@1.0:6"
```
Refactoring `SpackSolverSetup` is a bit easier with type annotations, so I started
adding some. This adds annotations for the (many) instance variables on
`SpackSolverSetup` as well as a few other places.
This also refactors `condition()` to reduce redundancy and to allow
`_get_condition_id()` to be called independently of the larger condition
function.

Some builds on Windows break when encountering paths with spaces. This
reencodes some paths in Windows 8.3 filename format (when on Windows):
this serves as an equivalent identifier for the file, but in a form that
does not have spaces.
8.3 filenames are also truncated in length, which could be helpful, but
that is not the primary intended purpose of using this format.
Overall
* nmake/msbuild packages do this generally for the install prefix
* curl/perl require additional modifications (as written now, each package
may require calls to `windows_sfn` to work when the Spack
root/install/staging prefixes contain spaces)
Some items for follow-up:
* Spack itself does not create paths with spaces "on top" of whatever
the user configures or where it is placed (e.g. the Spack root, the
staging directory, etc.), so it might be possible to edit some of these
paths once and avoid a proliferation of individual `windows_sfn`
calls in individual packages.
* This approach may result in the insertion of 8.3-style paths into
build artifacts (on Windows), handling this may require additional
bookkeeping (e.g. when relocating).
* Move spec_list into its own file, instead of __init__.py
* Remove spack.schema.spack
This module was introduced in #33960 It's almost an exact duplicate of
spack.schema.env, and is not used anywhere.

* cmake: Enable CMAKE_EXPORT_COMPILE_COMMANDS
Enabling this option causes CMake to generate a compile_commands.json file
containing a compilation database that can be used to drive third-party tools.
CMAKE_EXPORT_COMPILE_COMMANDS only exists for CMake >= 3.5
Exporting compilation databases is only supported for Makefile and Ninja
generators, so check these conditions as well.
CMAKE_EXPORT_COMPILE_COMMANDS is only enabled in supported configurations
This fixes bugs, performance issues, and removes no longer necessary code.
Short version:
1. Creating views from Python extensions would error if the Spack `opt` dir itself was in some symlinked directory. Use of `realpath` would expand those, and keying into `merge_map` would fail.
2. Creating views from Python extensions (and Python itself, potentially) could fail if the `bin/` dir contains symlinks pointing outside the package prefix -- Spack keyed into `merge_map[target_of_symlink]` incorrectly.
3. In the `python` package the `remove_files_from_view` function was broken after a breaking API change two years ago (#24355). However, the entire function body was redundant anyways, so solved it by removing it.
4. Notions of "global view" (i.e. python extensions being linked into Python's own prefix instead of into a view) are completely outdated, and removed. It used to be supported but was removed years ago.
5. Views for Python extension would _always_ copy non-symlinks in `./bin/*`, which is a big mistake, since all we care about is rewriting shebangs of scripts; we don't want to copy binaries. Now we first check if the file is executable, and then read two bytes to check if it has a shebang, and only if so, copy the entire file and patch up shebangs.
The bug fixes for (1) and (2) basically consist of getting rid of `realpath` entirely, and instead simply keep track of file identifiers of files that are copied/modified in the view. Only after patching up regular files do we iterate over symlinks and check if they target one of those. If so, retarget it to the modified file in the view.
These 7 hooks were not used.
- Six of them related to install phases were unused after `spack`
`monitor` was removed, and the code seems to have bit rotten as there
were reports they were not (always?) triggered when they should.
- The post environment one was made redundant after spack install for
environment started following the common code path for generating
module files in #42147.
It should not be a breaking change to remove, since users cannot define
hooks in extensions, they would have to fork Spack.
If we ever _were_ to make those hooks extendable outside of core Spack,
it would also be better to start with fewer rather than more, cause
everything you expose gets relied upon...
Removing those also allows us to rethink what hooks we really need, and
in particular it seems like we need a hook that runs post install also when
the spec is inserted into the database.
The lack of a rule to avoid enforcing requirements on multi-valued variants, when the condition activating the environment was not met, resulted in multiple optimal solutions. The fix is to prevent imposing a requirement if the when= rule activating it is not met.
The section was highly outdated as it referred to old defaults, and
failed to mention `hide_implicits: true`.
This commit restructures it, moves some deeply nested sections a level
up, and promotes `hide_implicits: true` + `autoload: direct` before
talking about `exclude`.
* Registry queries can fail due to simultaneous access from other
processes. Wrap some of these accesses and retry when this may
be the cause (the generated exceptions don't allow pinpointing
this as the reason, but we add logic to identify cases which
are definitely unrecoverable, and retry if it is not one of
these).
* Add make recursion optioal for most registry search functions;
disable recursive search in case where it was originally always
recursive.
Fix two separate problems:
1. We want to always visit parents before children while creating views
(when it comes to ignoring conflicts, the first instance generated in
the view is chosen, and we want the parent instance to have precedence).
Our preorder traversal does not guarantee that, but our topological-
order traversal does.
2. For copy style views with packages x depending on y, where
<x-prefix>/foo is a symlink to <y-prefix>/foo, we want to guarantee
that:
* A conflict is not registered
* <y-prefix>/foo is chosen (otherwise, the "foo" symlink would become
self-referential if relocated relative to the view root)
Note that
* This is an exception to [1] (in this case the dependency instance
overrides the dependent)
* Prior to this change, if "foo" was ignored as a conflict, it was
possible to create this self-referential symlink
Add tests for each of these cases
Sometimes the logs are too long and the copy & paste command is not
shown. In that case I'd like to just copy the failing GitLab job URL in
my browser to `spack reproduce-build <url>`.
Currently, the `SpackSolverSetup` and the `PyclingoDriver` are more coupled than necessary:
1. The driver object needs a setup object to be injected during a solve,
2. And the setup object will get a reference back to the driver
This design is necessary because we use the low-level `clingo.backend` interface to setup our problem. This interface though is meant to bypass the grounder and add symbols directly in the grounded table, which is a feature we don't currently use.
The PR simplifies the encoding by having the setup object returning the problem-specific facts / rules as a list of strings, and the driver ingesting them using the [clingo.Control.add](https://potassco.org/clingo/python-api/5.6/clingo/control.html#clingo.control.Control.add) method. This removes any use of the low level interface.
Using this encoding makes it easy to hash the output of the setup phase, since it is returned as a string.
This "breaks" the deprecated schema by allowing unknown attributes
to the attributes section of the job types. The breaking change here is
that deprecated stacks will no longer ignore attributes that are unknown
but rather assume the new CI schema behavior of injecting them into the
generated CI configuration. This change is required to secure
authentication in Spack CI.
Improve naming, so it's clear file "extensions" are not taken in the
`PurePath(path).suffix` sense as the original function name suggests,
but rather that the files are opened and their magic bytes are

Add type hints.
Fix a bug where `stream.read(num_bytes)` was run on the compressed
stream instead of the uncompressed stream, which can potentially break
detection of tar.bz2 files.
Ensure that when peeking into streams for magic bytes, they are reset to
their original position upon return.
Use new API in `spack logs`.
Relocation of `PT_INTERP` in ELF files already happens to work from long to short path, thanks to generic binary relocation (i.e. find and replace). This PR improves it:
1. Adds logic to grow `PT_INTERP` strings through patchelf (which is only useful if the interpreter and rpath paths are the _only_ paths in the binary that need to be relocated)
2. Makes shrinking `PT_INTERP` cleaner. Before this PR when you would use Spack-built glibc as link dep, and relocate
executables using its dynamic linker, you'd end up with
```
$ file exe
exe: ELF 64-bit LSD pie executable, ..., interpreter /////////////////////////////////////////////////path/to/glibc/lib/ld-linux.so
```
With this PR you get something sensible:
```
$ file exe
exe: ELF 64-bit LSD pie executable, ..., interpreter /path/to/glibc/lib/ld-linux.so
```
When Spack cannot modify the interpreter or rpath strings in-place, it errors out without modifying the file, and leaves both tasks to patchelf instead.
Also add type hints to `elf.py`.
Certain versions of ifx (the majority of those available) have an issue
where they are not compatible with TMP directories with dot chars
This precludes their use with CMake.
Remap TMP to point to the stage directory rather than whatever the TMP
default is
Add the empty deptype `spack.deptypes.NONE`.
Test the case `traverse_nodes(deptype=spack.deptypes.NONE)` to not
traverse dependencies, only de-duplicate.
Use the construct in environment views that otherwise would branch on
whether deps are enabled or not.
Previously, for abstract specs like:
```
foo ^[virtuals=a] bar ^[virtuals=b] bar
```
the second requirement was silently discarded on concretization. Now they're merged, and the abstract spec is equivalent to:
```
foo ^[virtuals=a,b] bar
```
CMake may write and read from `~/.cmake` through `export(...)` and read `find_package(...)` respectively. We don't want this as it may influence the build in a non-deterministic way, so disable it for all versions of `cmake`.
Fixes a bug where Spack did not generate module files of non-roots during
spack install with an active environment.
The reason being that Environment.new_installs only contained roots.
This PR:
Drops special casing of automatic module generation in post-install hooks
When `use_view`, compute environment variable modifications like always, and
applies a view projection to them afterwards, like we do for spack env activate.
This ensures we don't have to delay module generation until after the view is
created.
Fixes another bug in use_view where prefixes of dependencies would not be
projected -- previously Spack would only temporarily set the current spec's prefix.
Removes the one and only use of the post_env_write hook (but doesn't drop it to
make this backportable w/o changes)
Previously `std_args` was called on non-roots in a build context, which is redundant, and also leads to issues when `std_args` expects build deps of the `pkg` to be installed.
* Environments: fix environment config
* Don't change the lockfile manifest path
* Update activate's comments to tie the manifest to the configuration
* Add spec_list override method
* Remove type checking from 'activate' since already have built-in check
* Refactor global methods tied to the manifest to be in its class
* Restore Environment's 'env_subdir_path' and pass its config_stage_dir to EnvironmentManifestFile
* Restore global env_subdir_path for use by Environment and EnvironmentManifestFile
Currently requirements allow to express "strong preferences" and "conflicts" from
configuration using a convoluted syntax:
```yaml
packages:
zlib-ng:
require:
# conflict on %clang
- one_of: ["%clang", "@:"]
# Strong preference for +shared
- any_of: ["+shared", "@:"]
```
This PR adds syntactic sugar so that the same can be written as:
```yaml
packages:
zlib-ng:
conflict:
- "%clang"
prefer:
- "+shared"
```
Preferences written in this way are "stronger" that the ones documented at:
- https://spack.readthedocs.io/en/latest/packages_yaml.html#package-preferences
`spack install` early exit behavior was sometimes convenient, except
that it had and has bugs:
1. prior bug: we didn't mark env roots of already installed specs as
explicit in the db
2. current bug: `spack install --overwrite` is ignored
So this PR simplifies by letting the installer do its thing even if
everything is supposedly installed.
This commit ensures that CMake packages that also have Python as a build/link dep get a couple defines for the Python path so that CMake's builtin `FindPython3`, `FindPython`, `FindPythonInterp` modules can locate Python correctly.
The main problem with those CMake modules is that they first search for Python versions known at the time of release, meaning that old CMake maybe find older system Python 3.8 even though Python 3.11 comes first in `CMAKE_PREFIX_PATH` and `PATH`.
Package maintainers can opt out of this by overriding the `find_python_hints = False` attribute in the package class.
The piece of code that is removed in this PR predates environment views.
Spack would symlink build logs in `<env>/.spack-env/logs/*`, but this is
redundant because:
1. Views already add `<prefix>/.spack` (and there's logic there to avoid
clashes)
2. The code was broken anyways: it would only symlink the logs of
environment roots, not their deps, even if they were just built.
If users disable views, I'm pretty sure they're not waiting for
`.spack-env/logs` either. So, imo we can delete this code, and it was
probably overlooked in the past.
For a requirement like
```
packages:
foo:
require:
- "+debug"
```
(not `one_of:`, `any_of:`, or `spec:`)
`spack config change` would ignore the string. This was particularly evident if toggling a variant for a previously unmentioned package:
```
$ spack config change packages:foo:require:+debug
$ spack config change packages:foo:require:~debug
```
This fixes that and adds a test for it.
* Reduce the size on disk for logs
This PR does two things:
1. Store a compressed `spack-build-out.txt.gz`
2. Get rid of phase logs, as they are duplicates of
`spack-build-out.txt`
The logs are not compressed in the stage dir, so on build failure the
workflow for users is no different.
It's just that on install the logs are rarely used, and if needed, users
can easily `gzip -d` or `zgrep` them.
In the case of GCC installs, the compressed logs are <5% of the original
size, which is typically dozens of MBs.
* get rid of "backwards compat" of file names in stage dirs
Sbangs don't exist on Native Windows, and the hook is causing errors
due to the file comparison + behavior of os.rename on Windows. Skip
the hook on Windows.
Like `spack change` for specs in environments, this can e.g. replace `examplespec+debug` with `examplespec~debug` in a `require:` section.
Example behavior for a config like:
```
packages:
foo:
require:
- spec: +debug
```
* `spack config change packages:foo:require:~debug` replaces `+debug` with `~debug`
* `spack config change packages:foo:require:@1.1` adds a requirement to the list
* `spack config change packages:bar:require:~debug` adds a requirement
As observed in #40944, when using `spack config add <path>`, the `path` might
contain keys that are enclosed in quotes.
This was broken in https://github.com/spack/spack/pull/39831, which assumed that
only the value (if present, the final element of the path) would use quotes.
This preserves the primary intended behavior of #39931 (allowing ":" in values when
using `spack config add`) while also allowing quotes on keys.
This has complicated the function `process_config_path`, but:
* It is not used outside of `config.py`
* The docstring has been updated to account for this
* Created an object to formalize the DSL, added a test for that, and
refactored parsing to make use of regular expressions as well.
* Updated the parsing and also updated the `config_path_dsl` test with an explicit check.
At a higher level, split the parsing to check if something is either a key or not:
* in the first case, it is covered by a regex
* in the second, it may be a YAML value, but in that case it would have to be the last
entry of x:y:z, so in that case I attempt to use the YAML handling logic to parse it as such
Spack packages may not have a public download option, and can implement
`download_instr` to inform users how to obtain the artifacts needed to
build. `spack checksum` however did not account for this and would print
out a confusing error message when invoked on such packages ("Could not
find any remote versions").
This PR updates the error message to output the manual download instructions
if `spack checksum` is invoked on a package with `manual_download = True`.
Currently when you repeatedly create a bootstrap mirror that includes
`clingo-bootstrap@spack` you get different tarballs every time.
This is a general problem with mirroring checkouts from version control
as tarballs. I think it's best to create tarballs ourselves, since that way we
have more control over its contents.
This PR ensures normalized tarballs like we do for build caches:
- normalize file permissions (in fact that was already inspired by git, so
should be good)
- normalized file creation/modification time (timestamp 0)
- uid / guid = 0, no usernames
- normalized gzip header
- dir entries are ordered by `(is_dir, name)` where strings are not locale aware ;)
- POSIX says st_mode of symlinks is unspecified, so work around it and
force mode to `0o755`
Explicitly requested namespaces are annotated during
the setup phase, and used to retrieve the correct package
class.
An attribute for the namespace has been added for each node.
Currently, a single namespace per package is allowed
during concretization.
Add `--create` option to `env activate` to allow users to create and activate in one command.

This fixes an issue where pkg.stage throws because a patch cannot be found,
but the patch is redundant because the spec is reused from a build cache and
will be installed from existing binaries.
Part 4 of reworking all package metadata to key by `when` conditions.
Changes conflict dictionary structure from this:
{ provided_spec: {when_spec, ...} }
to this:
{ when_spec: {provided_spec, ...} }
`make_when_spec()` was being used in the solver, but it has semantics that are specific
to parsing when specs from `package.py`. In particular, it returns `None` when the
`when` spec is `False`, and directives are responsible for ignoring that case and not
adding requirements, deps, etc. when there's an actual `False` passed in from
`package.py`.
In `asp.py`, we know that there won't ever be a raw boolean when spec or constraint, so
we know we can parse them without any of the special boolean handling. However, we
should report where in the file the error happened on error, so this adds some parsing
logic to extract the `mark` from YAML and alert the user where the bad parse is.
- [x] refactor `config.py` so that basic `spack_yaml` mark info is in its own method
- [x] refactor `asp.py` so that it uses the smarter YAML parsing routine
- [x] refactor `asp.py` so that YAML input validation for requirements is done up front
Part 3 of reworking all package metadata to key by `when` conditions.
Changes conflict dictionary structure from this:
{ (requirement_spec, ...): [(when_spec, policy, msg)] }
to this:
{ when_spec: [((requirement_spec, ...), policy, msg), ...] }
Part 2 of reworking all package metadata to key by `when` conditions.
Changes conflict dictionary structure from this:
{ conflict_spec: [(when_spec, msg), ...] }
to this:
{ when_spec: [(conflict_spec, msg), ...] }
Also attempts to consistently name the variables used to iterate over conflict
dictionaries.
Part 1 of making all package metadata indexed by `when` condition. This
will allow us to handle all the dictionaries on `PackageBase` consistently.
Convert the current dependency dictionary structure from this:
{ name: { when_spec: [Dependency ...] } }
to this:
{ when_spec: { name: [Dependency ...] } }
On an M1 mac, this actually shaves 5% off the time it takes to load all
packages, I think because we're able to trade off lookups by spec key
for more lookups by name.
Needed for #40326, which can changes the iteration order over package dependencies during concretization.
While clingo doesn't have this problem, the original concretizer (which we still use for bootstrapping) can be sensitive to iteration order when evaluating dependency constraints in `when` conditions. This can cause it to ignore conditional dependencies unless the dependencies in the condition are listed first in the package.
The issue was in the way the original concretizer would disconnect specs *every* time `normalize()` ran. When specs were disconnected, `^dependency` constraints wouldn't see the dependency in the dependency condition loop.
We now only only disconnect *all* dependencies at the start of `concretize()` and `normalize()`, and we disconnect any leftover dependents from replaced externals at the *end* of `normalize()`. This trims stale connections while keeping the ones that are needed to trigger dependency conditions.
- [x] refactor `flat_dependencies()` to not disconnect the spec by default.
- [x] `flat_dependencies()` is never called with `copy=True` -- remove the `copy` kwarg.
- [x] disconnect only once at the beginning of `normalize()` or `concretize()`.
- [x] add a test that perturbs dependency iteration order to ensure this doesn't regress.
- [x] disconnect unused dependents at end of `normalize()`
This adds options to `spack list` that allow you to list only packages from specific
repositories/namespaces, e.g.:
```console
spack list -r builtin
```
only lists packages from the `builtin` repo, while:
```console
spack list -r myrepo -r myrepo2
```
would list packages from `myrepo` and `myrepo2`, but not from `builtin`. Note that you
can use the same argument multiple times.
You can use either `-r` / `--repo` or `-N` / `--namespace`. `-N` is there to match the
corresponding option on `spack find`.
- [x] add `-r` / `--repo` / `-N` / `--namespace` argument
- [x] add test
This method is vestigial; the only arg we ever used was `ignore=`, and that was
eliminated in #29317 and #35588.
The `kwargs` field of the extensions dictionary is actually completely unused now. Add a
note for future removal.
Literal compiler config in `test_requires_directive` specifically lists `target:
x86_64`, but it doesn't need to, and the unnecessary target makes the test fail on
non-`x86_64` machines.
- [x] Remove target from config yaml in `test_requires_directive`
* shell: fix zsh color formatting for PS1 in environments
The `colorize` function in `llnl.util.tty.color` only applies proper formatting for Bash
ANSI and for console output, but this is not what zsh expects for environment variables.
In particular, when using `zsh`, `spack env activate -p` produces a `PS1` prompt that
looks like this:
```
\[\033[0;92m\][ENVIRONMENT]\[\033[0m\]
```
For zsh the formatting should be:
```
\e[0;92m[ENVIRONMENT]\e0;m
```
- [x] Add a `zsh` option to `colorize()` to enable zsh color formatting
- [x] Add conditional to choose the right `PS1` for `zsh`, `bash`, and `sh`
- [x] Don't use color escapes for `sh`, as they don't print properly
* convert lots of += lines to triple quotes
Add a "checked_by" field to the `license()` directive so that we can track who verified
the license for a project. also check the license of 18 or so projects and mark them
checked.
This adds a few options to `spack gc`.
One to give you a little more control over dependencies:
* `-b` / `--keep-build-dependencies`: By default, `spack gc` considers build dependencies to be "no longer needed" once their dependents are installed. With this option, we'll keep build dependencies of needed installations as well.
And two more to make working with environments easier:
* `-E` / `--except-any-environment`: Garbage collect anything NOT needed by an environment. `spack gc -E` and `spack gc -bE` are now easy ways to get rid of everytihng not used by some environment.
* `-e` / `--except-environment` `ENV`: Instead of considering all environments, garbage collect everything not needed by a *specific* environment. Note that you can use this with `-E` to add directory environments to the list of considered envs, e.g.:
spack gc -E -e /path/to/direnv1 -e /path/to/direnv2 #...
- [x] rework `unused_specs()` method on DB to add options for roots and deptypes
- [x] add `all_hashes()` method on DB
- [x] rework `spack gc` command to add 3 more options
- [x] tests
To work properly, Spack requires a few directories from its repository to be added to
`sys.path`. Previously these were buried in `spack_installable.main.main()`, but it's
sometimes useful to get the paths separately, e.g., if you want to set up your own
functioning spack environment.
With this change, adding the paths is much simpler:
```python
import spack_installable
sys.path[:0] = get_spack_sys_paths(spack_prefix)
```
- [x] Add `get_spack_sys_paths()` method with extra paths in order.
- [x] Refactor `spack_installable.main.main()` to use it.
With an improper/incomplete/broken installation of Clingo, it can be
importable but not have any of the expected attributes
Improve error reporting in this case
* Restore PackageBase class, and modify only ASP
This prevents a noticeable slowdown in concretization
due to the number of directives involved.
* Fix issue with 'clang' being preferred to 'gcc',
due to runtime version weights
* Constraints on runtimes are declared by compilers
The declaration of available runtime versions, and of
their compatibility constraints are in the associated
compiler class.

The gcc-runtime package adds a separate node for gcc's dynamic runtime
libraries.
This should help with:
1. binary caches where rpaths for compiler support libs cannot be
relocated because the compiler is missing on the target system
2. creating "minimal" container images
The package is versioned like `gcc` (in principle it could be
unversioned, but Spack doesn't always guarantee not mixing compilers)
If you are calling Spack from the python API, you might have written something like this
before #41529:
```
find = SpackCommand("find")
find('--format={name}', 'saxpy@1.0.0', '+rocm', 'amdgpu_target="gfx90a"')
```
But with the breaking change in #41529, you should write:
```
find = SpackCommand("find")
find('--format={name}', 'gromacs', '+rocm', 'amdgpu_target=gfx90a')
```
Note that we don't need quotes in Python strings, and that this is what would come in
via argv if you typed a quoted variant on the CLI.
The error messages for strings like this are not great -- you get something like this:
```
==> No package matches the query: gromacs+rocm amdgpu_target="gfx90a"
```
Which doesn't indicate that the issue might be your quoting. This is because we were
simply outputting the argv we got, instead of using spec.format() to output the error
message. This PR fixes such errors to use `spec.format()` and to look like this:
```
==> No package matches the query: gromacs+rocm amdgpu_target='"gfx90a"'
```
So users should have an easier time understanding that Spack considers the variant value
to contain quotes here.
- [x] update ConstraintAction to store parsed Specs
- [x] refactor commands to display formatted parsed Specs instead of raw input
Users expect that changes to the externals sections in packages.yaml config apply immediately, but reuse concretization caused this not to be the case. With this commit, the concretizer is only allowed to reuse externals previously imported from config if identical config exists.
This PR adds a flag `--tag/-t` to `buildcache push`, which you can use like
```
$ spack mirror add my-oci-registry oci://example.com/hello/world
$ spack -e my_env buildcache push --base-image ubuntu:22.04 --tag my_custom_tag my-oci-registry
```
and lets users ship a full, installed environment as a minimal container image where each image layer is one Spack package, on top of a base image of choice. The image can then be used as
```
$ docker run -it --rm example.com/hello/world:my_custom_tag
```
Apart from environments, users can also pick arbitrary installed spec from their database, for instance:
```
$ spack buildcache push --base-image ubuntu:22.04 --tag some_specs my-oci-registry gcc@12 cmake
$ docker run -it --rm example.com/hello/world:some_specs
```
It has many advantages over `spack containerize`:
1. No external tools required (`docker`, `buildah`, ...)
2. Creates images from locally installed Spack packages (No need to rebuild inside `docker build`, where troubleshooting build failures is notoriously hard)
3. No need for multistage builds (Spack just tarballs existing installations of runtime deps)
4. Reduced storage size / composability: when pushing multiple environments with common specs, container image layers are shared.
5. Automatic build cache: later `spack install` of the env elsewhere speeds up since the containerized environment is a build cache
* add trim function to `Spec` and `--ignore` option to 'spack diff'
Allows user to compare two specs while ignoring the sub-DAG of a particular dependency, e.g.
spack diff --ignore=mpi --ignore=zlib trilinos/abcdef trilinos/fedcba
to focus on differences closer to the root of the software stack
Sometimes env variables computed in `setup_run_environment` depend on tests
w.r.t. files in `spec.prefix`, but Spack temporarily projects `spec.prefix` to
the view.
This is problematic for two reasons:
1. Some packages iterate over `<prefix>/bin`: they expect only the current
package's executables, but find all linked in the view, leading to false
positives.
2. Some packages test for `os.path.islink(...)`, which is always true in a view
`gcc` is an example that does both.
This PR lets Spack compute the environment modifications using the original
prefix, and projects to the view afterwards
Currently, a virtual spec is composed of just a name and a version. When a virtual spec contains other components, such as variants, Spack won't emit warnings or errors but will silently drop them - which is unexpected by users.
This PR changes the default behavior of `spack config get` and `spack config blame`
to print a flattened version of the entire spack configuration, including any active
environment, if the commands are invoked with no section arguments.
The new behavior is used in Gitlab CI to help debug CI configuration, but it can also
be useful when asking for more information in issues, or when simply debugging Spack.
Convert the 'develop' section of an environment to a dedicated configuration section.
This means for example that instead of having to define `develop` specs in the
`spack.yaml`, the environment can `include:` another `develop.yaml` configuration
which specifies which specs should be developed in the environment.
This change is not expected to be disruptive given that existing environment `spack.yaml`
files will conform to the new schema.
(Update 11/28/2023) I have implemented the `develop`/`undevelop` commands in terms
of more-generic modification functions added to the `config` module: `change_or_add`
and `update_all`. It is assumed that the semantics added here (described in 11/18 update)
would be desirable to extend to other config update actions (e.g. adding compilers,
changing package requirements, adding mirrors).
(Update 11/18/2023) I have updated this such that `spack develop`, and
`spack undevelop` to potentially modify all writable scopes, like
https://github.com/spack/spack/pull/41147. https://github.com/spack/spack/pull/35307
will be useful for modifying included scopes, but generally speaking specifying a
`--scope` will not be required for `spack develop`: `spack develop` will add new
develop specs to whatever scope already has develop specs defined, or to the
highest-priority writable scope (which should be the env scope).
TODOs:
- [x] If you `spack undevelop` a package which is mentioned at multiple layers of
configuration, then currently this would only modify one of them. That's not
technically a new issue (has always existed for configuration modification), but
may be confusing to users when presented via an interface other than `spack config set`
- [x] Need to add (or confirm) the ability to modify individual config files by providing
a path (rather than using a scope identifier as a key to retrieve associated config).
- [x] `spack develop` adds new develop specs to the scope that defines them
(potentially skipping higher priority scopes to e.g. augment included scope files)

This PR does several things:
- [x] Allow any character to appear in the quoted values of variants and flags.
- [x] Allow easier passing of quoted flags on the command line, e.g. `cflags="-O2 -g"`.
- [x] Handle quoting better in spec output, using single quotes around double
quotes and vice versa.
- [x] Disallow spaces around `=` and `==` when parsing variants and flags.
## Motivation
This PR is motivated by the issues above and by ORNL's
[tips for launching at scale on Frontier](https://docs.olcf.ornl.gov/systems/frontier_user_guide.html#tips-for-launching-at-scale).
ORNL recommends using `sbcast --send-libs` to broadcast executables and their
libraries to compute nodes when running large jobs (e.g., 80k ranks). For an
executable named `exe`, `sbcast --send-libs` stores the needed libraries in a
directory alongside the executable called `exe_libs`. ORNL recommends pointing
`LD_LIBRARY_PATH` at that directory so that `exe` will find the local libraries and
not overwhelm the filesystem.
There are other ways to mitigate this problem:
* You could build with `RUNPATH` using `spack config add config:shared_linking:type:runpath`,
which would make `LD_LIBRARY_PATH` take precedence over Spack's `RUNPATHs`.
I don't recommend this one because `RUNPATH` can cause many other things to go wrong.
* You could use `spack config add config:shared_linking:bind:true`, added in #31948, which
will greatly reduce the filesystem load for large jobs by pointing `DT_NEEDED` entries in
ELF *directly* at the needed `.so` files instead of relying on `RPATH` search via soname.
I have not experimented with this at 80,000 ranks, but it should help quite a bit.
* You could use [Spindle](https://github.com/hpc/Spindle) (as LLNL does on its machines)
which should transparently fix this without any changes to your executable and without
any need to use `sbcast` or other tools.
But we want to support the `sbcast` use case as well.
## `sbcast` and Spack
Spack's `RPATHs` break the `sbcast` fix because they're considered with higher precedence
than `LD_LIBRARY_PATH`. So Spack applications will still end up hitting the shared filesystem
when searching for libraries. We can avoid this by injecting some `ldflags` in to the build, e.g.,
if were were going to launch, say, `LAMMPS` at scale, we could add another `RPATH`
specifically for use with `sbcast`:
spack install lammps ldflags='-Wl,-rpath=$ORIGIN/lmp_libs'
This will put the `lmp_libs` directory alongside `LAMMPS`'s `lmp` executable first in the
`RPATH`, so it will be searched before any directories on the shared filesystem.
## Issues with quoting
Before this PR, the command above would've errored out for two reasons:
1. `$` wasn't an allowed character in our spec parser.
2. You would've had to double quote the flags to get them to pass through correctly:
spack install lammps ldflags='"-Wl,-rpath=$ORIGIN/lmp_libs"'
This is ugly and I don't think many users will easily figure it out. The behavior was added in
#29282, and it improved parsing of specs passed as a single string, e.g.:
spack install 'lammps ldflags="-Wl,-rpath=$ORIGIN/lmp_libs"'
but a lot of users are naturally going to try to quote arguments *directly* on the command
line, without quoting their entire spec. #29282 used a heuristic to detect unquoted flags
and warn the user, but the warning could be confusing. In particular, if you wrote
`cflags="-O2 -g"` on the command line, it would break the flags up, warn, and tell you
that you could fix the issue by writing `cflags="-O2 -g"` even though you just wrote
that. It's telling you to *quote* that value, but the user has to know to double quote.
## New heuristic for quoted arguments from the CLI
There are only two places where we allow arbitrary quoted strings in specs: flags and
variant values, so this PR adds a simpler heuristic to the CLI parser: if an argument in
`sys.argv` starts with `name=...`, then we assume the whole argument is quoted.
This means you can write:
spack install bzip2 cflags="-O2 -g"
directly on the command line, without multiple levels of quoting. This also works:
spack install 'bzip2 cflags="-O2 -g"'
The only place where this heuristic runs into ambiguity is if you attempt to pass
anonymous specs that start with `name=...` as one large string. e.g., this will be
interpreted as one large flag value:
spack find 'cflags="-O2 -g" ~bar +baz'
This sets `cflags` to `"-O2 -g" ~bar +baz`, which is likely not what you wanted. You
can fix this easily by either removing the quotes:
spack find cflags="-O2 -g" ~bar +baz
Or by adding a space at the start, which has the same effect:
spack find ' cflags="-O2 -g" ~bar +baz'
You may wonder why we don't just look for quotes inside of flag arguments, and the
reason is that you *might* want them there. If you are passing arguments like:
spack install zlib cppflags="-D DEBUG_MSG1='quick fox' -D DEBUG_MSG2='lazy dog'"
You *need* the quotes there. So we've opted for one potentially confusing, but easily
fixed outcome vs. limiting what you can put in your quoted strings.
## Quotes in formatted spec output
In addition to being more lenient about characters accepted in quoted strings, this PR fixes
up spec formatting a bit. We now format quoted strings in specs with single quotes, unless
the string has a single quote in it, in which case we JSON-escape the string (i.e., we add
`\` before `"` and `\`).
zlib cflags='-D FOO="bar"'
zlib cflags="-D FOO='bar'"
zlib cflags="-D FOO='bar' BAR=\"baz\""
MySQL was performing a core API call to `Spec.flat_dependencies`
when setting up the build environment. This function is an
implementation detail of the old concretizer, where multiple nodes
from the same package are not allowed.
This PR uses a more idiomatic way to check if "python" is
in the DAG.
For reference, see #11356 to check why the call was introduced.

Fix filer_compiler_wrapper for cases where the compiler returned in None, this happens on some installed gcc systems that do not have fortran built into them as standard, e.g. gcc@11.4.0 on ubuntu 22.04
Before (hard to read, doesn't fit on small terminals):
:
```console
-I, --install-status show install status of packages
packages can be: installed [+], missing and needed by an installed package [-], installed in an upstream instance [^], or not installed (no annotation)
```
After (fits in 80 columns):
```console
-I, --install-status show install status of packages
[+] installed [^] installed in an upstream
- not installed [-] missing dep of installed package
```
* Fix cdash reporter time stamps (#38818).
The cdash reporter is created before packages are installed so save the
starttime then instead of the endtime.
* Use endtime instead of starttime for the endtime of update

- we don't have a fallback if make is not installed
- we assume file system locking works
- we don't verify that make is gnu make (bootstrapping fails on FreeBSD as a result)
- there are some weird race conditions in writing spack.yaml on concurrent spack install
- the view is updated after every package install instead of post environment install.
Forbid nested dependencies in depends_on declarations, by running an audit in CI.
Fix the packages not passing the new audit:
- amd-aocl
- exago
- palace
- shapemapper
- xsdk-examples
ginkgo: add a commit sha to v1.5.0.glu_experimental
This was missed while backporting the new `spack info` command from #40326.
Variants should be sorted by name when invoking `spack info --variants-by-name`.
