Source mirrors store entries by digest and add a human readable alias of the
form 'name-version'. If no digest is available, the alias is used as the primary
storage location.
Spack erroneously fetches by alias when the digest path does not exist. This is
problematic if `version(..., sha256=...)` changes in package.py, and the mirror
is populated with the old shasum. That would result in an error when a digest
is available, but in case of git versions with a modified commit sha, the wrong
sources would be fetched without error. With this PR, only the digest path is
used, not the alias, in case a digest is available. This is also a small performance
optimization, as the number of request is halved for mirrors that don't contain
the sources.
Further, for git sources the tag was used as a digest, but this is a moving
target. Only commit sha is used now.
Also whenever the alias already existed, Spack used to keep it in place when
updating the mirror cache, which means that aliases would always point to
outdated mirror entries whenever digests are modified. With this PR the alias
is moved in place.
Lastly, fix a recent regression where `Stage.disable_mirrors` disabled mirrors
but not the local download cache, which was the intention.
* Add missing MultiMethodMeta metaclass in builders
and remove the Python 2 fallback option in favor of hard errors to catch
similar issues going forward.
The fallback option can cause about 10K stat calls due to use of
`realpath` in the inspect module, depending on how deep Spack itself is
nested in the file system, which is ... undesirable.
* code shuffling to avoid circular import
* more reshuffling
* move reserved variant names into variants module
* Adds an MSBuild system + Builder to the icu4c package
* Adds custom install method as MSBuild system does not vendor an
install target
* The cxxstd variant is not supported on Windows (there are no config
options you use to tell the build system what cxx standard to
build against), so the variant definition was updated to occur
everywhere except Windows
Also, this commit defines the c/cxx..._flag properties of the MSVC
compiler (although they are not used by `icu4c` and not strictly
necessary to bundle with this PR).
Paths over 260 characters in length are not handled by `shutil.rmtree`
unless they use the extended-length path syntax (using a prefix of
"\\?\").
This fixes an issue where stage cleaning fails when paths in a stage
exceed the normal 260-character limit.
This indicates that other parts of the codebase should be examined/
refactored to handle long paths.
Previously `spack buildcache push --only=package` errored in the OCI
case, but it's been requested that OCI can be used as pure storage w/o
the need for runnable container images.
This commit makes it so that
1. manifests refer only to runtime dependencies that were selected to be
pushed
2. failure to upload a blob among the selected specs does not prevent a
manifest/tag to be created for dependents: they just don't refer to
the missing blob as a layer/dependency
This fixes the following issues:
1. dependents of non-redistributable specs can now be pushed to oci
build caches without error
2. failure to upload one tarball does not cause cascading failures for
dependents whose tarballs do upload succesfully -- so it's better
best-effort behavior
3. for some people uploading with deps caused a massive amount of
fetches of their manifests (which certain registries count as a
download of an image, even though their layers are not fetched) --
being able to specify --only=package reduces the number of fetches.
Stage objects create mirrors ad-hoc from current config.
- There is no way to prevent mirrors from being used
- There is no way to restrict mirrors to source/binary, which is of
course context dependent.
- Stage is also used in build caches, where iterating over mirrors is
already implemented differently, and wouldn't work anyways cause it's
source only, and in particular it makes no sense for OCI build caches.
This commit:
1. Injects the sensible mirrors into the stage object from contexts
where it is relevant
2. Separates mirrors from cache, so that w/o mirrors download cache can
still be used
The test_foreground_background unit test has been marked
xfail for a while, meaning:
- Nobody looks at the results of the test
- It still runs every time
That test happens to hang frequently on some Apple M1 I have access to,
so here I mark it as skip.
Also went through other xfailing and skipped tests, and applied minor changes.
* Use absolute paths instead of https:// fake mirrors (this speed-up tests by avoiding requests)
* Add a fixture to gather in a single place code that is copy/pasted in a lot of tests
* General clean-up of tests and repeated code

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

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

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

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

For example: spack install py-pyqt5 or py-pyqt6 would install pylupdate5 pyrcc5 and
pyuic5 into in python-venv's install prefix.
