From 31d12d380fdbd5c71a02645515d062cfbcc12017 Mon Sep 17 00:00:00 2001 From: Peter Scheibel Date: Fri, 1 May 2020 10:47:46 -0700 Subject: Testing: fix unintended interactions between tests (#16003) * For tests that use the real Spack package repository, the config needs to avoid using MPI providers that are not intended to be installed by Spack. Without this, it is possible that Spack tests which concretize the MPI virtual will end up trying to use an implementation that it shouldn't (e.g. one that is always provided externally). See #15666 for an example. * The mutable_config test fixture was not initializing the scope roots to the right directories (so the resulting config was empty). * The current_host fixture in the concretize.py tests was using the config fixture rather than mutable_config, and was polluting the config cache for other tests. * One test in concretize.py was clearing a nonexistent cache (PackagePrefs._packages_config_cache). This reference has been removed. * The test 'test_preferred_compilers' was was depending on cross test config pollution to succeed. The initial spec before concretization has been updated to updated to be explicit about the desired result. --- lib/spack/spack/cmd/compiler.py | 14 +++++++++++++- lib/spack/spack/test/concretize.py | 8 ++++---- lib/spack/spack/test/concretize_preferences.py | 2 +- lib/spack/spack/test/conftest.py | 4 ++-- lib/spack/spack/test/data/config/packages.yaml | 3 +++ 5 files changed, 23 insertions(+), 8 deletions(-) (limited to 'lib') diff --git a/lib/spack/spack/cmd/compiler.py b/lib/spack/spack/cmd/compiler.py index 625466f8c7..c8f52af04d 100644 --- a/lib/spack/spack/cmd/compiler.py +++ b/lib/spack/spack/cmd/compiler.py @@ -159,7 +159,19 @@ def compiler_list(args): tty.msg("Available compilers") index = index_by(spack.compilers.all_compilers(scope=args.scope), lambda c: (c.spec.name, c.operating_system, c.target)) - ordered_sections = sorted(index.items(), key=lambda item: item[0]) + + # For a container, take each element which does not evaluate to false and + # convert it to a string.
