Example 16 with WalkableGraph

use of com.google.devtools.build.skyframe.WalkableGraph in project bazel by bazelbuild.

the class PrepareDepsOfTargetsUnderDirectoryFunctionTest method testTransitiveLoading.

@Test
public void testTransitiveLoading() throws Exception {
    // Given a package "a" with a genrule "a" that depends on a target in package "b",
    createPackages();
    // When package "a" is evaluated,
    SkyKey key = createPrepDepsKey(rootDirectory, new PathFragment("a"));
    EvaluationResult<?> evaluationResult = getEvaluationResult(key);
    WalkableGraph graph = Preconditions.checkNotNull(evaluationResult.getWalkableGraph());
    // Then the TransitiveTraversalValue for "@//a:a" is evaluated,
    SkyKey aaKey = TransitiveTraversalValue.key(Label.create("@//a", "a"));
    assertThat(exists(aaKey, graph)).isTrue();
    // And that TransitiveTraversalValue depends on "@//b:b.txt".
    Iterable<SkyKey> depsOfAa = Iterables.getOnlyElement(graph.getDirectDeps(ImmutableList.of(aaKey)).values());
    SkyKey bTxtKey = TransitiveTraversalValue.key(Label.create("@//b", "b.txt"));
    assertThat(depsOfAa).contains(bTxtKey);
    // And the TransitiveTraversalValue for "b:b.txt" is evaluated.
    assertThat(exists(bTxtKey, graph)).isTrue();
}

Example 17 with WalkableGraph

use of com.google.devtools.build.skyframe.WalkableGraph in project bazel by bazelbuild.

the class PrepareDepsOfPatternsFunctionSmartNegationTest method assertSkipsFoo.

private void assertSkipsFoo(ImmutableList<String> patternSequence) throws Exception {
    // When PrepareDepsOfPatternsFunction completes evaluation (successfully),
    WalkableGraph walkableGraph = getGraphFromPatternsEvaluation(patternSequence, /*successExpected=*/
    true, /*keepGoing=*/
    true);
    // Then the graph contains a package value for "@//foo",
    assertTrue(exists(PackageValue.key(PackageIdentifier.parse("@//foo")), walkableGraph));
    // But no package value for "@//foo/foo",
    assertFalse(exists(PackageValue.key(PackageIdentifier.parse("@//foo/foo")), walkableGraph));

    Label label = Label.create("@//foo/foo", "foofoo");
    assertFalse(exists(getKeyForLabel(label), walkableGraph));
}

Example 18 with WalkableGraph

use of com.google.devtools.build.skyframe.WalkableGraph in project bazel by bazelbuild.

the class PrepareDepsOfPatternsFunctionSmartNegationTest method testRecursiveEvaluationFailsOnBadBuildFile.

    // recovered from),
    WalkableGraph walkableGraph = getGraphFromPatternsEvaluation(patternSequence, /*successExpected=*/
    true, /*keepGoing=*/

    // Then the graph contains package values for "@//foo" and "@//foo/foo",
    assertTrue(exists(PackageValue.key(PackageIdentifier.parse("@//foo")), walkableGraph));
