示例1: CreateSlaveFlags

// This test verifies the case where we don't need a bind mount for
// slave's working directory because the mount containing it is
// already a shared mount in its own peer group.
TEST_F(LinuxFilesystemIsolatorTest, ROOT_WorkDirMountNotNeeded)
{
  Try<string> directory = environment->mkdtemp();
  ASSERT_SOME(directory);

  // Make 'sandbox' a shared mount in its own peer group.
  ASSERT_SOME(os::shell(
      "mount --bind %s %s && "
      "mount --make-private %s &&"
      "mount --make-shared %s",
      directory->c_str(),
      directory->c_str(),
      directory->c_str(),
      directory->c_str()));

  // Slave's working directory is under 'sandbox'.
  slave::Flags flags = CreateSlaveFlags();
  flags.work_dir = path::join(directory.get(), "slave");

  ASSERT_SOME(os::mkdir(flags.work_dir));

  Try<Isolator*> isolator = LinuxFilesystemIsolatorProcess::create(flags);
  ASSERT_SOME(isolator);

  Try<fs::MountInfoTable> table = fs::MountInfoTable::read();
  ASSERT_SOME(table);

  // Verifies that there's no mount for slave's working directory.
  bool mountFound = false;
  foreach (const fs::MountInfoTable::Entry& entry, table->entries) {
    if (entry.target == flags.work_dir) {
      mountFound = true;
    }
  }

  EXPECT_FALSE(mountFound);

  delete isolator.get();
}
