Examples with MetadataHandler com.google.devtools.build.lib.actions.cache.MetadataHandler used on opensource projects

Example 1 with MetadataHandler

use of com.google.devtools.build.lib.actions.cache.MetadataHandler in project bazel by bazelbuild.

the class TreeArtifactBuildTest method testDigestInjection.

// This is more a smoke test than anything, because it turns out that:
// 1) there is no easy way to turn fast digests on/off for these test cases, and
// 2) injectDigest() doesn't really complain if you inject bad digests or digests
// for nonexistent files. Instead some weird error shows up down the line.
// In fact, there are no tests for injectDigest anywhere in the codebase.
// So all we're really testing here is that injectDigest() doesn't throw a weird exception.
// TODO(bazel-team): write real tests for injectDigest, here and elsewhere.
