Change the signature of Spec.from_detection to set the
external prefix, and the external modules, if they are
present.
Delete "spack.package_prefs.spec_externals" since it
is unused.
This context manager was used to prevent detecting a platform
as "cray". Since now Cray machines are detected as linux, we can
remove the context manager.
Right now if you run `spack ci generate` you get a warning about CDash credentials even
if there's no CDash configuration specified. We should only warn if there was actually a
CDash config.

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outdated mirror entries whenever digests are modified.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
* Adding sparse clone test
* Add test for partial clone
* [@spackbot] updating style on behalf of psakievich
* Small fixes
* Restore default branch status
* Fix attributes for package
* Update lib/spack/docs/packaging_guide.rst

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.
