Example 18 with StringValue

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

the class MemoizingEvaluatorTest method dirtyAndChangedValueIsChanged.

/**
   * Test whether a value that was already marked changed will be incorrectly marked dirty, not
   * changed, if another thread tries to mark it just dirty. To exercise this, we need to have a
   * race condition where both threads see that the value is not dirty yet, then the "changed"
   * thread marks the value changed before the "dirty" thread marks the value dirty. To accomplish
   * this, we use a countdown latch to make the "dirty" thread wait until the "changed" thread is
   * done, and another countdown latch to make both of them wait until they have both checked if the
   * value is currently clean.
