Problem: when calling `static_to_shared_library` on the `cray` arch, it
produces a non-sensical compiler command with no input files. For
example, when installing lua@5.2.4, it produced:
'gcc -lm -ldl -o /big-long-spack-path/liblua.so.5.2.4'
Solution: do the same thing on `cray` that is done for `linux`
* account for schema validation errors where the associated instance doesn't have a line number
* fix unrelated flake error (but it must be fixed because this PR touches this file and the flake rules have been updated since the last edit to this file)
Allows `all` to be configured non-buildable in packages.yaml.
The following config would only allow zlib to be built by Spack, all other packages would have to be found as externals.
```
packages:
all:
buildable: False
zlib:
buildable: True
```
This change also adds a code path through the spack ci pipelines
infrastructure which supports PR testing on the Spack repository.
Gitlab pipelines run as a result of a PR (either creation or pushing
to a PR branch) will only verify that the packages in the environment
build without error. When the PR branch is merged to develop,
another pipeline will run which results in the generated binaries
getting pushed to the binary mirror.
Providing only $padding or ${padding} results in an attempt to
substitute a padding of maximum system path length, while leaving
room for the parts of the install path spack generates. Providing
$padding-<len> or ${padding-<len>} simply substitutes padding of
the specified length.
Packages built with lmod core_compiler are placed in `Core`.
Other packages may belong in `Core`. For example, python may be built with a proprietary compiler for performance, but belong on the `Core` directory.
With this PR, lmod config can include a `core_specs` list. Any package that satisfies a spec in that list is placed in `Core`, regardless of its compiler or dependencies.
This improves the documentation for `spack external find` in several ways:
* Provide a code example of implementing `determine_spec_details` for a package
* Explain how to define executables to look for (and also e.g. that they are treated as regular expressions and so can pull in unexpected files).
* Add the "why" for a couple of constraints (i.e. explain that this logic only works for build/run deps because it examines `PATH` for executables)
* Spread the docs between build customization and packaging sections
* Add cross-references
* Add a label so that `spack external find` is linked from the command reference.
* Add pmi support (required by ucx, ofi, and gni backends)
* Add support for ucx backend
* Add dependency on MPI for pmi=simplepmi, slurmpmi, or slurmpmi2
* Remove charmpp as an MPI provider since the changes in this PR can
add MPI as a dependency (mentioned previously)
* Install into transport_protocol-OS-arch subdirectory to match
default charmpp installation behavior (which helps dependents find it)
- add docstrings and make parameter names consistent in `relocate.py`
- Make `replace_prefix_*` and other functions private (as they are implementation details)
- remove unused function _replace_prefix_nullterm()
- Add unit tests for `relocate.py` functions
- add patchelf to Travis and use it during tests
- add hello_world fixture with a compiled binary, so we can test relocation
After migrating to `travis-ci.com`, we saw I/O issues in our tests --
tests that relied on `capfd` and `capsys` were failing. We've also seen
this in GitHub actions, and it's kept us from switching to them so far.
Turns out that the issue is that using streams like `sys.stdout` as
default arguments doesn't play well with `pytest` and output redirection,
as `pytest` changes the values of `sys.stdout` and `sys.stderr`. if these
values are evaluated before output redirection (as they are when used as
default arg values), output won't be captured properly later.
- [x] replace all stream default arg values with `None`, and only assign stream
values inside functions.
- [x] fix tests we didn't notice were relying on this erroneous behavior
This adds the `url` alternative `urls` to `package.all_urls`. With
this addition, one can find again new versions with
`spack versions <package>` for packages that are populated with
from mixin mirror `urls`.
Example: `util-macros` from x.org mixin.

This fixes some errors with setting up test configuration. These
errors do not cause current Spack tests to fail but do create
red herring issues elsewhere (see #15666). Fixing these errors
leads to more errors in tests that depended on the original
misconfigured state, so those are also addressed here.
This is an update to #16003 which accounts for some unit tests with
conflicting config/mutable_config fixtures. These conflicts were
not exposed until the mutable_config fixture was fixed. Details are
included below. The change which builds on #16003 is prefixed with
"(new)".
* For tests that use the real Spack package repository, the config
needs to avoid using MPI providers that are not intended to be
installed by Spack. Without this, it is possible that Spack tests
which concretize the MPI virtual will end up trying to use an
implementation that it shouldn't (e.g. one that is always
provided externally). See #15666 for an example.
* The mutable_config test fixture was not initializing the scope
roots to the right directories (so the resulting config was empty).
* The current_host fixture in the concretize.py tests was using the
config fixture rather than mutable_config, and was polluting the
config cache for other tests.
* One test in concretize.py was clearing a nonexistent cache
(PackagePrefs._packages_config_cache). This reference has been
removed.
* The test 'test_preferred_compilers' was was depending on cross
test config pollution to succeed. The initial spec before
concretization has been updated to updated to be explicit about
the desired result.
* (new) For tests that use install_mockery and mutable_config,
replace install_mockery with a separate install_mockery_mutable_config
fixture that is exactly the same as install_mockery but uses the
mutable_config fixture to avoid conflicts.
Fixed#15884.
Spack asks every package linked into an environment to tell us how
environment variables should be modified when a spack environment is
activated. As part of this, specs in an environment are symlinked into
the environment's view (see #13249), and the package calculates
environment modifications with *the default view as the prefix*.
All of this works nicely for pointing the user's environment at the view
*if* every package is successfully linked. Unfortunately, right now we
only track what specs "should" be in a view, not which specs actually
are. So we end up calculating environment modifications on things that
aren't linked into thee view, and the exception isn't caught, so lots of
spack commands end up failing.
This fixes the issue by ignoring and warning about specs where
calculating environment modifications fails. So we can still keep using
Spack even if the current environment is incomplete.
We should probably also just avoid computing env modifications *entirely*
for unlinked packages, but right now that is a slow operation (requires a
lot of YAML parsing). We should revisit that when we have some better
state management for views, but the fix adopted here will still be
necessary, as we want spack commands to be resilient to other types of
bugs in `setup_run_environment()` and friends. That code is in packages
and we have to assume it could be buggy when we call it outside of builds
(as it might fail more than just the build).
Add a `spack external find` command that tries to populate
`packages.yaml` with external packages from the user's `$PATH`. This
focuses on finding build dependencies. Currently, support has only been
added for `cmake`.
For a package to be discoverable with `spack external find`, it must define:
* an `executables` class attribute containing a list of
regular expressions that match executable names.
* a `determine_spec_details(prefix, specs_in_prefix)` method
Spack will call `determine_spec_details()` once for each prefix where
executables are found, passing in the path to the prefix and the path to
all found executables. The package is responsible for invoking the
executables and figuring out what type of installation(s) are in the
prefix, and returning one or more specs (each with version, variants or
whatever else the user decides to include in the spec).
The found specs and prefixes will be added to the user's `packages.yaml`
file. Providing the `--not-buildable` option will mark all generated
entries in `packages.yaml` as `buildable: False`
Cray has two machine types. "XC" machines are the larger
machines more common in HPC, but "Cluster" machines are
also cropping up at some HPC sites. Cluster machines run
a slightly different form of the CrayPE programming environment,
and often come without default modules loaded. Cluster
machines also run different versions of some software, and run
a linux distro on the backend nodes instead of running Compute
Node Linux (CNL).
Below are the changes made to support "Cluster" machines in
Spack. Some of these changes are semi-related general upkeep
of the cray platform.
* cray platform: detect properly after module purge
* cray platform: support machines running OSs other than CNL
Make Cray backend OS delegate to LinuxDistro when no cle_release file
favor backend over frontend OS when name clashes
* cray platform: target detection uses multiple strategies
This commit improves the robustness of target
detection on Cray by trying multiple strategies.
The first one that produces results wins. If
nothing is found only the generic family of the
frontend host is used as a target.
* cray-libsci: add package from NERSC
* build_env: unload cray-libsci module when not explicitly needed
cray-libsci is a package in Spack. The cray PrgEnv
modules load it implicitly when we set up the compiler.
We now unload it after setting up the compiler and
only reload it when requested via external package.
* util/module_cmd: more robust module parsing
Cray modules have documentation inside the module
that is visible to the `module show` command.
Spack module parsing is now robust to documentation
inside modules.
* cce compiler: uses clang flags for versions >= 9.0
* build_env: push CRAY_LD_LIBRARY_PATH into everything
Some Cray modules add paths to CRAY_LD_LIBRARY_PATH
instead of LD_LIBRARY_PATH. This has performance benefits
at load time, but leads to Spack builds not finding their
dependencies from external modules.
Spack now prepends CRAY_LD_LIBRARY_PATH to
LD_LIBRARY_PATH before beginning the build.
* mvapich2: setup cray compilers when on cray
previously, mpich was the only mpi implementation to support
cray systems (because it is the MPI on Cray XC systems).
Cray cluster systems use mvapich2, which now supports cray
compiler wrappers.
* build_env: clean pkgconf from environment
Cray modules silently add pkgconf to the user environment
This can break builds that do not user pkgconf.
Now we remove it frmo the environment and add it again if it
is in the spec.
* cray platform: cheat modules for rome/zen2 module on naples/zen node
Cray modules for naples/zen architecture currently specify
rome/zen2. For now, we detect this and return zen for modules
named `craype-x86-rome`.
* compiler: compiler default versions
When detecting compiler default versions for target/compiler
compatibility checks, Spack previously ran the compiler without
setting up its environment. Now we setup a temporary environment
to run the compiler with its modules to detect its version.
* compilers/cce: improve logic to determine C/C++ std flags
* tests: fix existing tests to play nicely with new cray support
* tests: test new functionality
Some new functionality can only be tested on a cray system.
Add tests for what can be tested on a linux system.

Add the same fix for the amgx and lammps packages
If spack is checked out in a git worktree (see [1]), all git-related
commands fail because the `spack_is_git_repo()`-check is not thorough
enough.
When developing in a feature-branch in a seperate worktree, this is
annoying as all unittests regarding git-related spack commands fail,
cluttering the test results with false-positives.

* dev-build: --drop-in <shell>
Add a `--drop-in <shell>` option to `spack dev-build`.
This option will automatically run a
`spack build-env <spec> -- <shell>` at the end of a `dev-build`, e.g.
to quickly drop-and-devel into a build phase of a package.
Example usage:
```
spack dev-build --before cmake --drop-in bash openpmd-api@develop
```
* build_env: drop in unit test

Generally speaking, errors that are encountered when attempting to load
command extensions now terminate the running Spack instance.
* Added new exceptions `spack.cmd.PythonNameError` and
`spack.cmd.CommandNameError`.
* New functions `spack.cmd.require_python_name(pname)` and
`spack.cmd.require_cmd_name(cname)` check that `pname` and `cname`
respectively meet requirements, throwing the appropriate error if not.
* `spack.cmd.get_module()` uses `require_cmd_name()` and passes through
exceptions from module load attempts.
* `spack.cmd.get_command()` uses `require_cmd_name()` and invokes
`get_module()` with the correct command-name form rather than the
previous (incorrect) Python name.
* Added New exceptions `spack.extensions.CommandNotFoundError` and
`spack.extensions.ExtensionNamingError`.
* `_extension_regexp` has a new leading underscore to indicate expected
privacy.
* `spack.extensions.extension_name()` raises an `ExtensionNamingError`
rather than using `tty.warn()`.
* `spack.extensions.load_command_extension()` checks command source
existence early and bails out if missing. Also, exceptions raised by
`load_module_from_file()` are passed through.
* `spack.extensions.get_module()` raises `CommandNotFoundError` as
appropriate.
* Spack `main()` allows `parser.add_command()` exceptions to cause
program end.
Tests:
* More common boilerplate has been pulled out into fixtures including
`sys.modules` dictionary cleanup and resource-managed creation of a
simple command extension with specified contents in the source file
for a single named command.
* "Hello, World!" test now uses a command named `hello-world` instead of
`hello` in order to verify correct handling of commands with hyphens.
* New tests for:
* Missing (or misnamed) command.
* Badly-named extension.
* Verification that errors encountered during import of a command are
propagated upward.
