From 23e85f4086e0fe4d885cf765d7d7684e2016f036 Mon Sep 17 00:00:00 2001 From: Massimiliano Culpo Date: Fri, 8 Apr 2022 23:26:17 +0200 Subject: Environments: unify the spec objects on first concretization (#29948) Currently environments are indexed by build hashes. When looking into this bug I noticed there is a disconnect between environments that are concretized in memory for the first time and environments that are read from a `spack.lock`. The issue is that specs read from a `spack.lock` don't have a full hash, since they are indexed by a build hash which is strictly coarser. They are also marked "final" as they are read from a file, so we can't compute additional hashes. This bugfix PR makes "first concretization" equivalent to re-reading the specs from a corresponding `spack.lock`, and doing so unveiled a few tests were we were making wrong assumptions and relying on the fact that a `spack.lock` file was not there already. * Add unit test * Modify mpich to trigger jobs in pipelines * Fix two failing unit tests * Fix another full_hash vs. build_hash mismatch in tests --- lib/spack/spack/environment/environment.py | 26 ++++++++++++++++++++++++-- lib/spack/spack/test/ci.py | 12 ++++++++++++ lib/spack/spack/test/cmd/ci.py | 4 ++-- lib/spack/spack/test/cmd/install.py | 2 +- 4 files changed, 39 insertions(+), 5 deletions(-) (limited to 'lib') diff --git a/lib/spack/spack/environment/environment.py b/lib/spack/spack/environment/environment.py index 72df9cbfe3..b6875653df 100644 --- a/lib/spack/spack/environment/environment.py +++ b/lib/spack/spack/environment/environment.py @@ -1271,11 +1271,33 @@ class Environment(object): finish = time.time() tty.msg('Environment concretized in %.2f seconds.' % (finish - start)) - results = [] + by_hash = {} for abstract, concrete in zip(root_specs, concretized_root_specs): self._add_concrete_spec(abstract, concrete) - results.append((abstract, concrete)) + by_hash[concrete.build_hash()] = concrete + + # Unify the specs objects, so we get correct references to all parents + self._read_lockfile_dict(self._to_lockfile_dict()) + + # Re-attach information on test dependencies + if tests: + # This is slow, but the information on test dependency is lost + # after unification or when reading from a lockfile. + for h in self.specs_by_hash: + current_spec, computed_spec = self.specs_by_hash[h], by_hash[h] + for node in computed_spec.traverse(): + test_deps = node.dependencies(deptype='test') + for test_dependency in test_deps: + if test_dependency in current_spec[node.name]: + continue + current_spec[node.name].add_dependency_edge( + test_dependency.copy(), deptype='test' + ) + results = [ + (abstract, self.specs_by_hash[h]) for abstract, h in + zip(self.concretized_user_specs, self.concretized_order) + ] return results def concretize_and_add(self, user_spec, concrete_spec=None, tests=False): diff --git a/lib/spack/spack/test/ci.py b/lib/spack/spack/test/ci.py index 9d653be35c..c8b91ced23 100644 --- a/lib/spack/spack/test/ci.py +++ b/lib/spack/spack/test/ci.py @@ -579,3 +579,15 @@ def test_get_spec_filter_list(mutable_mock_env_path, config, mutable_mock_repo): 'libelf']) assert affected_pkg_names == expected_affected_pkg_names + + +@pytest.mark.regression('29947') +def test_affected_specs_on_first_concretization(mutable_mock_env_path, config): + e = ev.create('first_concretization') + e.add('hdf5~mpi~szip') + e.add('hdf5~mpi+szip') + e.concretize() + + affected_specs = spack.ci.get_spec_filter_list(e, ['zlib']) + hdf5_specs = [s for s in affected_specs if s.name == 'hdf5'] + assert len(hdf5_specs) == 2 diff --git a/lib/spack/spack/test/cmd/ci.py b/lib/spack/spack/test/cmd/ci.py index ce6359fcf8..22e72973ec 100644 --- a/lib/spack/spack/test/cmd/ci.py +++ b/lib/spack/spack/test/cmd/ci.py @@ -1731,12 +1731,12 @@ spack: job_spec_yaml_path = os.path.join( working_dir.strpath, 'archivefiles.yaml') with open(job_spec_yaml_path, 'w') as fd: - fd.write(job_spec.to_yaml(hash=ht.full_hash)) + fd.write(job_spec.to_yaml(hash=ht.build_hash)) root_spec_yaml_path = os.path.join( working_dir.strpath, 'root.yaml') with open(root_spec_yaml_path, 'w') as fd: - fd.write(root_spec.to_yaml(hash=ht.full_hash)) + fd.write(root_spec.to_yaml(hash=ht.build_hash)) artifacts_root = os.path.join(working_dir.strpath, 'scratch_dir') pipeline_path = os.path.join(artifacts_root, 'pipeline.yml') diff --git a/lib/spack/spack/test/cmd/install.py b/lib/spack/spack/test/cmd/install.py index cc99c7d6a3..3fdfe24aa4 100644 --- a/lib/spack/spack/test/cmd/install.py +++ b/lib/spack/spack/test/cmd/install.py @@ -851,7 +851,7 @@ def test_install_no_add_in_env(tmpdir, mock_fetch, install_mockery, # but not added as a root mpi_spec_yaml_path = tmpdir.join('{0}.yaml'.format(mpi_spec.name)) with open(mpi_spec_yaml_path.strpath, 'w') as fd: - fd.write(mpi_spec.to_yaml(hash=ht.full_hash)) + fd.write(mpi_spec.to_yaml(hash=ht.build_hash)) install('--no-add', '-f', mpi_spec_yaml_path.strpath) assert(mpi_spec not in e.roots()) -- cgit v1.2.3-60-g2f50
