* Introduce FFTW2 and FFT3 providers for Intel-MKL and FFTW Spack packages.
* make fftw default package for fftw-api virtual package
* virtual package test assertion now provides location of default virtual packages.
* Change name of virtual package to fftw-api and used versioned interface.
- all commands (except `spack find`, through `ConstraintAction`) now go
through get_env() to get the active environment
- ev.active was hard to read -- and the name wasn't descriptive.
- rename it to _active_environment to be more descriptive and to strongly
indicate that spack.environment manages it
- to aovid changing spec hashes drastically, only add this attribute to
differentiated abstract specs.
- othherwise assume that read-in specs are concrete
- spack.yaml files in the current directory were picked up inconsistently
-- make this a sure thing by moving that logic into find_environment()
and moving find_environment() to main()
- simplify arguments to Spack command:
- remove short args for infrequently used commands (--pdb/-D, -P, -s)
- `spack -D` now forces an env with a directory
- The `Spec` class maintains a special `_patches_in_order_of_appearance`
attribute on patch variants, but it is was preserved when specs are
copied.
- This caused issues for some builds
- Add special logic to `Spec` to preserve this variant on copy
- TODO: in the long term we should get rid of the special variant and
make it the responsibility of one of the variant classes.
- split 'environment' section into 'environments' and 'modules'
- move location to 'query packages' section
- move cd to developer section
- --env-dir no longer has a short optino (was -E)
- -E now means "run without an environment" (no longer same as --env-dir)
- -D now means "run with this directory environment"
- remove short options for may infrequently used top-level commands
- `spack env status` used to show install status; consolidate that into
`spack find`.
- `spack env status` will still print out whether there is an active
environment
- uninstall now:
- restricts its spec search to the current environment
- removes uninstalled specs from the current environment
- reports envs that still need specs you're trying to uninstall
- removed spack env uninstall command
- updated tests
- moved get_env from cmd/env.py to environment.py
- spack install will now install into the active environment when no
arguments are provided. It looks:
1. at the command line
2. for a local spack.yaml file
3. for any currently activated environment
- `spack env create <name>` works as before
- `spack env create <path>` now works as well -- environments can be
created in their own directories outside of Spack.
- `spack install` will look for a `spack.yaml` file in the current
directory, and will install the entire project from the environment
- The Environment class has been refactored so that it does not depend on
the internal Spack environment root; it just takes a path and operates
on an environment in that path (so internal and external envs are
handled the same)
- The named environment interface has been hoisted to the
spack.environment module level.
- env.yaml is now spack.yaml in all places. It was easier to go with one
name for these files than to try to handle logic for both env.yaml and
spack.yaml.
- `spack env activate foo`: sets SPACK_ENV to the current active env name
- `spack env deactivate`: unsets SPACK_ENV, deactivates the environment
- added support to setup_env.sh and setup_env.csh
- other env commands work properly with SPACK_ENV, as with an environment
arguments.
- command-line --env arguments take precedence over the active
environment, if given.
- env.yaml is now meaningful; it contains authoritative user specs
- concretize diffs user specs in env.yaml and env.json to allow user to
add/remove by simply updating env.yaml
- comments are preserved when env.yaml is updated by add/unadd
- env.yaml can contain configuration and include external configuration
either from merged files or from config scopes
- there is only one file format to remember (env.yaml, no separate init
format)
- env.json is now env.lock, and it stores the *last* user specs to be
concretized, along with full provenance.
- internal structure was modified slightly for readability
- env.lock contains a _meta section with metadata, in case needed
- added more tests for environments
- env commands follow Spack conventions; no more `spack env foo install`
- add `SingleFileScope` to configuration, which allows us to pull config
sections from a single file.
- update `env.yaml` and tests to ensure that the env.yaml schema works
when pulling configurtion from the env file.
- Each schema now has a top-level `properties` and `schema` attribute.
- The `properties` is a fragment that can be included in other
jsonschemas, via Python, not via '$ref'
- Th `schema` is a complete `jsonschema` with `title` and `$schema`
properties.
- add a common argument for `-e/--env`
- modify the database to support queries on subsets of hashes
- allow `spack find` to be filtered by hashes in an environment
- logic used in `spack find` was hiding duplicate installations if their
hashes were different
- short hash doesn't work in this scenario, since specs are structurally
identical
- ConstraintAction always works on a DB query, so use the DAG hash to
ensure uniqueness
- `spack.environment` is now the home for most of the infrastructure
around Spack environments
- refactor `cmd/env.py` to use everything from spack.environment
- refactor the cmd/env test to use pytest and fixtures
- `spack.util.environment` is the new home for routines that modify
environment variables.
- This is to make room for `spack.environment` to contain new routines
for dealing with spack environments
- Instead of one method with all parsers, each subcommand gets two
functions: `setup_<cmd>_parser()` and `environment_<cmd>()`
- the `setup_parser()` and `env()` functions now generate the parser
based on these and a list of subcommands.
- it is now easier to associate the arguments with the subcommand.
