- 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.
* PackageMeta: `run_before` is an alias of `precondition`, `run_after` an alias of `sanity_check`
* PackageMeta: removed `precondition` and `sanity_check`
* PackageMeta: decorators are now free-standing
* package: modified/added docstrings. Fixed the semantics of `on_package_attributes`.
* package: added unit test assertion as side effects of install
* build_systems: factored build-time test running into base class
* r: updated decorators in package.py
* docs: updated decorator names
- 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
* Removing the nobuild, nolink, and alldeps dependency types in favor of being explicit.
* This will help with maintenance going forward, as adding more dependency types won't affect existing declared dependencies in weird ways.
* default deptype is still `('build', 'link')`
Package repositories now look like this:
top-level-dir/
repo.yaml
packages/
libelf/
package.py
mpich/
package.py
...
This leaves room at the top level for additional metadata, source,
per-repo configs, indexes, etc., and it makes it easy to see that
something is a spack repo (just look for repo.yaml and packages).
