We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
This PR implements several refactors requested in #11373, specifically:
- Config scopes are used to handle builtin defaults, command line overrides
and package overrides (`parallel=False`)
- `Package.make_jobs` attribute has been removed; `make_jobs` remains
as a module-scope variable in the build environment.
- The use of the argument `-j` has been rationalized across commands
- move '-j'/'--jobs' argument into `spack.cmd.common.arguments`
- Add unit tests to check that setting parallel jobs works as expected
- add new test to ensure that build job setting is isolated to each build
- Fix packages that used `Package.make_jobs` (i.e. `bazel`)
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
Building bazel yielded errors since commit cd9691d. The first commit
fixes the build for older bazel versions, the second commit adds new
versions and ports the patches to these versions.
Fixes#6521.
Bazel's build system filters environment variables, including those
set by Spack for use by its compiler wrapper. This updates the patch
to include the SPACK_DEBUG_LOG_ID variable added in #5837.
