Includes :
- treatment of a generic hierarchy (i.e. lapack + mpi + compiler)
- possibility to specify which compilers are to be considered Core
- correct treatment of the 'family' directive
- unit tests for most new features
- Spack will check if the index needs updating, and will only parse
all package files if it does.
- Spack tries to parse as few package files as necessary.
- Default scope is versioned with spack and can be overridden by site
or user config.
- Default scope provides sensible default concretization preferences
for all of Spack.
- per-platform concretization scope can be added later (to force a
particular MPI on, e.g., Cray systems)
- User and site config are now kept separately in memory.
- Merging is done on demand when client code requests the configuration.
- Allows user/site config to be updated independently of each other by commands.
- simplifies config logic (no more tracking merged files)
- New spack.hooks package
- contains modules with pre and post install hooks
- New dotkit hook module
- generates/removes dotkits on install/uninstall
- New spack use, spack unuse commands
- use same syntax as install/uninstall
- New setup-env.bash script
- Sets up path, dotkit support
- new spack dotkit command
- used by script to parse specs, generate
specs of installed pckages for dotkit file names
- Allow version wildcards to match [_-.] instead of the exact separators
the version was constructed with.
- Handles the fact that boost versions are written both 1.55.0 and 1_55_0.
- Update spidering to handle parse errors and warn that Python < 2.7.3 has
less robust HTML parsing abilities.
