- Spack core has long used llnl.util.filesystem.join_path, but
os.path.join is pretty much the same thing, and is more efficient.
- Use os.path.join in the core Spack code from now on.
- simplify the singleton pattern across the codebase
- reduce lines of code needed for crufty initialization
- reduce functions that need to mess with a global
- Singletons whose semantics changed:
- spack.store.store() -> spack.store
- spack.repo.path() -> spack.repo.path
- spack.config.config() -> spack.config.config
- spack.caches.fetch_cache() -> spack.caches.fetch_cache
- spack.caches.misc_cache() -> spack.caches.misc_cache
- `spack.cmd.all_commands` does a directory listing on
`lib/spack/spack/cmd`, regardless of whether it is needed
- make this lazy so that the directory listing won't happen unless it's
necessary.
- It turns out that jsonschema is one of the more expensive imports.
- move imports of jsonschema into functions to avoid the performance hits
for calls that don't need config.
- spack.store was previously initialized at the spack.store module level,
but this means the store has to be initialized on every spack call.
- this moves the state in spack.store to a singleton so that the store is
only initialized when needed.
- spack.repository module is now spack.repo
- `spack.repo` is now `spack.repo.path()` and loaded lazily
- Added `spack.repo.get()` and `spack.repo.all_package_names()` as
convenience functions to simplify the new lazy interface.
- updated tests and code
- no longer require `spack_version` to be a Version (it isn't used that
way anyway)
- use a simple tuple `spack_version_info` with major, minor, patch
versions
- generate `spack_version` from the tuple
- replace `spack.config.get_configuration()` with `spack.config.config()`
- replace `get_config`/`update_config` with `get`, `set`
- add a path syntax that can be used to refer to specific config options
without firt getting the entire configuration dict
- update usages of `get_config` and `update_config` to use `get` and `set`
- Current configuration code forces the config system to be initialized
at module scope, so configs are parsed on every Spack run, essentially
before anything else.
- We need more control over configuration init order, so move the config
scopes into a class and reduce global state in config.py
Fixes#8152
Flex 2.6.4 doesn't build with gcc@7:. This sets Flex 2.6.3 as the
preferred version. The flex package had a conflict directive for
this but originally the recorded conflict was specific to ubuntu;
this appears to be an issue on multiple operating systems so this
also updates the conflict to be more general and adds a comment
which links to the relevant issues.
Fixes#7946
Creates an openspeedshop-utils package that does not depend on qt3
and can be used to resolve the needs of cbtf-argonavis-gui.
Changes for creating a release versus develop build are also
included. There are package versions which are no longer relevant
(e.g. 1.3.0 for cbtf-argonavis-gui has been replaced with 1.3.0.0)
but these versions need to be kept to allow uninstalling them;
issue #8173 has been created to investigate this.
- After spack install, these test cases are built in a seperate step, outside of spack, but they need to patched after staging so users don't have to do it in a seperate step.
- The test cases are installed under `<petsc install directory>/share/petsc/examples` and can be built and executed by invoking `gmake -f gmakefile.test` in that directory.
