From e85a8cde37fbc1568a12d89b3de372bdfb9c8d93 Mon Sep 17 00:00:00 2001 From: Paul Ferrell <51765748+Paul-Ferrell@users.noreply.github.com> Date: Wed, 24 Feb 2021 11:57:50 -0700 Subject: Config prefer upstream (#21487) This allows for quickly configuring a spack install/env to use upstream packages by default. This is particularly important when upstreaming from a set of officially supported spack installs on a production cluster. By configuring such that package preferences match the upstream, you ensure maximal reuse of existing package installations. --- lib/spack/spack/cmd/config.py | 88 +++++++++++++++++++++++++++++++++++++- lib/spack/spack/config.py | 2 +- lib/spack/spack/test/cmd/config.py | 50 ++++++++++++++++++++++ 3 files changed, 138 insertions(+), 2 deletions(-) (limited to 'lib') diff --git a/lib/spack/spack/cmd/config.py b/lib/spack/spack/cmd/config.py index 81136d7859..cc7923d450 100644 --- a/lib/spack/spack/cmd/config.py +++ b/lib/spack/spack/cmd/config.py @@ -17,6 +17,8 @@ import spack.environment as ev import spack.schema.packages import spack.util.spack_yaml as syaml from spack.util.editor import editor +import spack.store +import spack.repo description = "get and set configuration options" section = "config" @@ -73,6 +75,16 @@ def setup_parser(subparser): help="file from which to set all config values" ) + prefer_upstream_parser = sp.add_parser( + 'prefer-upstream', + help='set package preferences from upstream') + + prefer_upstream_parser.add_argument( + '--local', action='store_true', default=False, + help="Set packages preferences based on local installs, rather " + "than upstream." + ) + remove_parser = sp.add_parser('remove', aliases=['rm'], help='remove configuration parameters') remove_parser.add_argument( @@ -431,6 +443,79 @@ def config_revert(args): tty.msg(msg.format(cfg_file)) +def config_prefer_upstream(args): + """Generate a packages config based on the configuration of all upstream + installs.""" + + scope = args.scope + if scope is None: + scope = spack.config.default_modify_scope('packages') + + all_specs = set(spack.store.db.query(installed=True)) + local_specs = set(spack.store.db.query_local(installed=True)) + pref_specs = local_specs if args.local else all_specs - local_specs + + conflicting_variants = set() + + pkgs = {} + for spec in pref_specs: + # Collect all the upstream compilers and versions for this package. + pkg = pkgs.get(spec.name, { + 'version': [], + 'compiler': [], + }) + pkgs[spec.name] = pkg + + # We have no existing variant if this is our first added version. + existing_variants = pkg.get('variants', + None if not pkg['version'] else '') + + version = spec.version.string + if version not in pkg['version']: + pkg['version'].append(version) + + compiler = str(spec.compiler) + if compiler not in pkg['compiler']: + pkg['compiler'].append(compiler) + + # Get and list all the variants that differ from the default. + variants = [] + for var_name, variant in spec.variants.items(): + if (var_name in ['patches'] + or var_name not in spec.package.variants): + continue + + if variant.value != spec.package.variants[var_name].default: + variants.append(str(variant)) + variants.sort() + variants = ' '.join(variants) + + if spec.name not in conflicting_variants: + # Only specify the variants if there's a single variant + # set across all versions/compilers. + if existing_variants is not None and existing_variants != variants: + conflicting_variants.add(spec.name) + pkg.pop('variants', None) + elif variants: + pkg['variants'] = variants + + if conflicting_variants: + tty.warn( + "The following packages have multiple conflicting upstream " + "specs.
