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
Seamless translation from 'target=<generic>' to either
- target.family == <generic> (in methods)
- 'target=<generic>:' (in directives)
Also updated docs to show ranges in directives.
- 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
* Change path to CMakeLists.txt to be relative to root, not pwd
* Changes requested during code review
* Revert back to old naming of root_cmakelists_dir
* Make relative directory more clear in docs
* Revert change causing build_type AttributeError
* Fix forgotten abs_path var
* Update CLHEP with new relative path
* Update more packages with new root_cmakelists_dir syntax
* libwebsockets: new versions
both new versions fix a nasty bug leading to a hanging
connection on connect.
* ISAAC Server: Fix libwebsockets
ISAAC server did hang in docker containers due to a bug
in libwebsockets.
Somehow the path to `CMakeLists.txt` via the class property
`root_cmakelists_dir` was relative but is now actually relative
to `spack-build/`.
Close 4324 by providing a path relative to the source repo
of the stage via a method instead of a member variable
