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
- 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
- Spack doesn't need eggs -- it manages its own directories
- Simplify install layout and reduce sys.path searches by installing all
packages flat (eggs are deprecated for wheels, and this is also what
wheels do).
- We now supply the --single-version-externally-managed argument to
`setup.py install` for setuptools packages and setuptools.
- modify packages to only use setuptools args if setuptools is an
immediate dependency
- Remove setuptools from packages that do not need it.
- Some packages use setuptools *only* when certain args (likeb
'develop' or 'bdist') are supplied to setup.py, and they specifically
do not use setuptools for installation.
- Spack never calls setup.py this way, so just removing the setuptools
dependency works for these packages.
- Add a PythonPackage class with build system support.
- Support build phases in PythonPackage
- Add a custom sanity check for PythonPackages
- Get rid of nolink dependencies in python packages
- Update spack create to use new PythonPackage class
- Port most of Python packages to new PythonPackage class
- Conducted a massive install and activate of Python packages.
- Fixed bugs introduced by install and activate.
- Update API docs on PythonPackage
