* initial work to make use of an 'upstream' spack installation: this uses the DB of the upstream installation to check if a package is installed
* need to query upstream dbs when adding new record to local db
* prevent reindexing upstream DBs
* set prefix on specs read from DB based on path stored in install record
* check that Spack does not install packages that are recorded as installed in an upstream db
* externals do not add their path to install records - need to use 'external_path' to get path of upstream externals
* views need to check for upstream installations when linking metadata
* package and spec now calculate upstream installation properties on-demand themselves rather than depending on concretization to set these properties up-front. The added tests for upstream installations don't work with this new strategy so they need to be updated
* only refresh modules for local specs (not those in upstream packages); optionally generate local module files for packages installed upstream
* when a user tries to locate a module file for a package installed upstream, tell them to use the upstream spack instance to locate it
* support recursive upstream databases (allow upstream databases to use their own upstream databases)
* separate upstream config into separate file with its own schema; each entry now also includes a name
* metadata_dir is no longer customizable on a per-instance basis for YamlDirectoryLayout
* treat metadata_dir as an instance variable but dont set it from kwargs; this follows several other hardcoded variables which must be consistent between upstream and downstream DBs. Also update DirectoryLayout.metadata_path to work entirely with Spec.prefix, since Spec.prefix is set from the DB when available (so metadata_path was duplicating that logic)
* Add latest libyogrt versions
* Add url_for_version to handle differing url formats for different
versions
* Add 'scheduler' variant to configure scheduler. Currently only
slurm can be installed with Spack. A value of 'system' indicates
to use the scheduler installed on the system
* py-prompt-toolkit: Add newer version for required for newer
py-ipython versions
* py-ipykernel:
* Add newer py-ipykernel version
* Depend on py-setuptools so a python egg isn't attempted to be
built
* Update dependency for newer py-ipykernel versions
* py-jupyter-console: Remove py-prompt-toolkit dependency since it is
picked up in py-ipython
* py-ipython:
* Add missing py-backcall dependency
* Adjust py-prompt-toolkit dependencies for newer versions of
ipython
* py-jupyter-notebook: Require newer version of py-ipykernel since
jupyter is broken with previous versions
* add cxxstd variant
* add CMake constraints based on platform/version
* add older versions
* update boost dependency version constraints (which are closely
tied to mysql version) and update boost cxxstd choice to be
the same as the cxxstd chosen for mysql
* add client-only support (including a patch for 5.5.x)
* record the mysql package as a provider of the mysql-client virtual
Improve management of the Fiber library and C++ standard support:
* Remove Fiber from list of libraries to build
* Improve variant management for Fiber; add variants for Context and
Coroutine libraries.
* Add known conflict with C++17 for boost < 1.63.0
* Remove C++ standard "default" option, which left the choice of
C++ standard to the compiler used to build boost
* record conflicts with compiler versions which don't provide
required c++ standard support
* add doxygen (build) dependency
* add note that range-v3 is header-only as of 0.3.6 and update
package description
We add new variants to handle readline vs libedit, a client-only
build and install, and bindings to TCL, Python and Perl. We also add
new versions and the ability to detect remote versions not otherwise
dealt with.
This avoids using a system-installed CUDA package. In the future a
variant can be added to allow using Spack-installed CUDA, but for
now CUDA support is always disabled.
